Ecological Informatics

Wikipedia: Ecological Informatics Ecoinformatics, or ecological informatics, is the science of information (Informatics) in Ecology and Environmental science. It integrates environmental and information sciences to define entities and natural processes with language common to both humans and computers. However, this is a rapidly developing area in ecology and there are alternative perspectives on what constitutes ecoinformatics. A few definitions have been circulating, mostly centered on the creation of tools to access and analyze natural system data. However, the scope and aims of ecoinformatics are certainly broader than the development of metadata standards to be used in documenting datasets. Ecoinformatics aims to facilitate environmental research and management by developing ways to access, integrate databases of environmental information, and develop new algorithms enabling different environmental datasets to be combined to test ecological hypotheses. Ecoinformatics characterize the semantics of natural system knowledge. For this reason, much of today's ecoinformatics research relates to the branch of computer science known as Knowledge representation, and active ecoinformatics projects are developing links to activities such as the Semantic Web. Current initiatives to effectively manage, share, and reuse ecological data are indicative of the increasing importance of fields like Ecoinformatics to develop the foundations for effectively managing ecological information. Examples of these initiatives are the National Science Foundation's Datanet , DataONE and Data Conservancy projects.

Linking spatial metaphors to body size perception: Different roles of top-down associations and multisensory contributions when mapping auditory cues to finger length.

Cortex; a journal devoted to the study of the nervous system and behavior, 190:178-191 pii:S0010-9452(25)00172-8 [Epub ahead of print].

Temporospatial and semantic multisensory aspects contribute to bodily and spatial perception. An informative paradigm to study this is the Auditory Pinocchio Illusion, in which participants perceive an elongation of their finger upon vertically pulling their finger and hearing a concurrent upward pitch glissando. This arguably relies on anchoring (i.e., associating) the ecologically unrelated upward pitch glissando to the finger and allows to separately assess the role of semantic and multisensory contributions. However, what is needed for this anchoring to occur is unknown. In a first Experiment, we manipulated top-down attention to the finger upon which either an ascending or descending sound would be produced. In a second experiment, we compared how different bottom-up multisensory cues (arising from actions performed on the finger) concurrent to the ascending or descending pitch affected finger length perception. Participants either pulled, touched or stretched their finger. Through a perceptual judgment task of finger landmark localization and questionnaire ratings, we measured participants' perceived finger length in both studies and separately assessed their sensory imagery skills. Our results show that attention alters finger length perception according to questionnaire ratings but not perceptual judgements, while concurrent multisensory signals similarly affect both measures. No relationship between these effects and participants' sensory imagery was found. We suggest that while top-down associations between pitch and verticality are necessary and affect questionnaire ratings, they are not sufficient to affect perceptual judgements. Bottom-up somatosensory cues seem to be additionally needed to impact such judgements in this illusion.

Applying multilevel selection to understand cancer evolution and progression.

PLoS biology, 23(7):e3003290 pii:PBIOLOGY-D-25-01107 [Epub ahead of print].

Natural selection occurs at multiple levels of organization in cancer. At an organismal level, natural selection has led to the evolution of diverse tumor suppression mechanisms, while at a cellular level, it favors traits that promote cellular proliferation, survival and cancer. Natural selection also occurs at a subcellular level, among collections of cells and even among collections of organisms; selection at these levels could influence the evolution of cancer and cancer suppression mechanisms, affecting cancer risk and treatment strategies. There may also be cancer-like processes happening at different levels of organization, in which uncontrolled proliferation at lower levels may disrupt a higher level of organization. This Essay examines how selection operates across levels, highlighting how we might leverage this understanding to improve cancer research, prevention and treatment.

If You're Rare, Should I Care? How Imperfect Detection Changes Relationships Between Biodiversity and Global Change Drivers.

Global change biology, 31(7):e70362.

Across ecosystems and biomes, most species in biological communities are rare. Many studies discount rare species when examining biodiversity patterns, assuming that common species are most influential for ecosystem functioning. There is growing evidence, however, that rare species contribute unique functions in many ecosystems; thus, discounting them produces misleading conclusions about how biodiversity is changing in the face of natural and anthropogenic forces. Rare species are more likely to be missed by multi-species sampling designs and are thus particularly vulnerable to detection error. Best practice in biodiversity assessments should include rare species and account for error in the detection process. We outline a general approach that accounts for detection error in sampling designs using multi-species occupancy and abundance models (MSOM/MSAM). We then show how uncertainty in detection can be propagated from MSOM/MSAM results to derive more accurate estimates of alpha and beta diversity metrics. Finally, we show how uncertainty in these diversity metrics can be accounted for in follow-up regression models to evaluate relationships between biodiversity and global change covariates. Using three case studies across diverse taxa (birds, insects, and plants), we demonstrate how accounting for the detection process alters the relationships between biodiversity and global change drivers in ways that are important for understanding and predicting ongoing change in these communities. Our generalizable analysis approach can aid in accounting for rare species in studies of global biodiversity.

Evaluation of DNA barcoding reference databases for marine species in the western and central Pacific Ocean.

PeerJ, 13:e19674.

DNA barcoding is a widely used tool for species identification, with its reliability heavily dependent on reference databases. While the quality of these databases has long been debated, a critical knowledge gap remains in their comprehensive evaluation and comparison at regional scales. Marine metazoan species in the western and central Pacific Ocean (WCPO), a region characterized by high biodiversity and limited sequencing efforts, are an example of this gap. This study developed a systematic workflow to assess mitochondrial cytochrome c oxidase subunit I (COI) barcode coverage and sequence quality in two commonly used reference databases for DNA barcoding: the nucleotide reference database from the National Center for Biotechnology Information (NCBI); and from the Barcode of Life Data System (BOLD). Comparative analyses across marine phyla and WCPO regions identified significant barcode gaps and quality problems, providing insights to guide future barcoding efforts. NCBI exhibited higher barcode coverage, but lower sequence quality compared to BOLD. Quality issues, including over- or under-represented species, short sequences, ambiguous nucleotides, incomplete taxonomic information, conflict records, high intraspecific distances, and low inter-specific distances were identified in both databases, likely resulting from contamination, cryptic species, sequencing errors, or inconsistent taxonomic assignment. The barcode identification number (BIN) system in BOLD demonstrated potential for identifying and addressing problematic records, highlighting the benefits of curated databases. Significant barcode deficiencies and quality issues were observed in the south temperate region of WCPO and phyla such as Porifera, Bryozoa, and Platyhelminthes. Additionally, the COI barcode showed limited species-level resolution for certain taxa, including Scombridae and Lutjanidae. Addressing barcode coverage gaps, improving taxonomic representation, and enhancing sequence quality will be essential for strengthening future barcoding initiatives and advancing biodiversity monitoring and conservation in the WCPO and beyond. This study highlights the need for standardized database curation and sequencing practices to improve the global reliability and applicability of DNA barcoding.

Anti-epidemic pharmaceuticals predominantly contributed to PPCPs flux in the Yangtze River during 2020.

Water research, 286:124228 pii:S0043-1354(25)01135-2 [Epub ahead of print].

The COVID-19 pandemic triggered a surge in pharmaceutical consumption, yet its impact on large-scale riverine systems remains poorly quantified. This study investigated the spatiotemporal distribution, sources and transport flux of 58 pharmaceuticals and personal care products (PPCPs) across the Yangtze River Basin (3400 km mainstream and 8 tributaries) during 2020. The mean concentration of PPCPs was 200.2 ± 205.7 ng/L in 2020, with caffeine (28.2 %), carbamazepine (13.2 %), and metronidazole (9.2 %) as dominant compounds. It was estimated that 449.8 tons of PPCPs were discharged into the sea via the Yangtze River in 2020, of which 48 % (216.0 tons) originated from COVID-19-related pharmaceuticals (e.g., metronidazole, diclofenac). Compared to pre-pandemic levels (2018), the river experienced additional pollution pressure from 209.6 tons of COVID-19 related pharmaceutical emissions. Source apportionment identified post-consumer anthropogenic activities (domestic discharges, clinical effluent outflows, and veterinary applications) as primary contributors (p < 0.05), while industrial sources associated with pharmaceutical production contributed little. Low ecological risks were observed in the study area, likely attributable to high wastewater treatment rates (>90 % in most cities) and the high efficacy of centralized wastewater management. This study provided the first basin-scale quantitative evidence of pandemic-driven PPCP pollution, offering critical insights for balancing public health emergencies with sustainable water resource governance.

Development and extensive sequencing of a broadly-consented Genome in a Bottle matched tumor-normal pair.

Scientific data, 12(1):1195.

The Genome in a Bottle Consortium (GIAB), hosted by the National Institute of Standards and Technology (NIST), is developing new matched tumor-normal samples, the first explicitly consented for public dissemination of genomic data and cell lines. Here, we describe a comprehensive genomic dataset from the first individual, HG008, including DNA from an adherent, epithelial-like pancreatic ductal adenocarcinoma (PDAC) tumor cell line and matched normal cells from duodenal and pancreatic tissues. Data for the tumor-normal matched samples comes from seventeen distinct state-of-the-art whole genome measurement technologies, including high depth short and long-read bulk whole genome sequencing (WGS), single cell WGS, Hi-C, and karyotyping. These data will be used by the GIAB Consortium to develop matched tumor-normal benchmarks for somatic variant detection. We expect these data to facilitate innovation for whole genome measurement technologies, de novo assembly of tumor and normal genomes, and bioinformatic tools to identify small and structural somatic variants. This first-of-its-kind broadly consented open-access resource will facilitate further understanding of sequencing methods used for cancer biology.

Incidence of type 2 diabetes by socioeconomic deprivation in Germany between 2014 and 2019: an ecological study.

BMJ open, 15(7):e094824.

OBJECTIVE: To estimate type 2 diabetes incidence trends by sex and socioeconomic position (SEP) and evaluate trends in SEP-related inequalities in incidence.

DESIGN: Ecological study using ambulatory claims data and regression-based modelling.

SETTING: All 401 counties in Germany, covering the entire country.

PARTICIPANTS: All individuals with statutory health insurance (~85% of the population). Incident cases of type 2 diabetes were identified annually from 2014 to 2019 using the International Statistical Classification of Diseases and Related Health Problems, 10th revision codes.

Incident type 2 diabetes at the county level, adjusted for age and modelled using a mixed negative binomial regression. SEP was measured using the German Index of Socioeconomic Deprivation, and a random intercept accounted for county-level heterogeneity.

RESULTS: The incidence of type 2 diabetes decreased between 2014 and 2017 and plateaued thereafter. Trends were similar between sexes and deprivation levels. The greatest difference was observed between high and low deprivation, with an incidence rate ratio of 1.20 (95% CI: 1.14 to 1.27) among men and 1.21 (95% CI: 1.14 to 1.27) among women in 2014.

CONCLUSIONS: There was a positive trend in the decline in age-adjusted type 2 diabetes incidence between 2014 and 2019. However, social inequality persisted with deprived groups at higher risk of type 2 diabetes. The level of inequality was comparable between men and women. Continued monitoring is essential to assess whether these short-term trends persist over time.

A Vision for VenomsBase: An Integrated Knowledgebase for the Study of Venoms and Their Applications.

Integrative organismal biology (Oxford, England), 7(1):obaf026.

Venoms are complex bioactive mixtures that have independently evolved across diverse animal lineages, including snails, insects, sea anemones, spiders, scorpions, and snakes. Despite the growing interest in venom research, data is fragmented across disparate databases which lack standardization and interoperability. A vision for the proposed VenomsBase platform presented here seeks to address these challenges by using the best practices approach in creating a centralized, open-access platform adhering to FAIR principles (Findable, Accessible, Interoperable, and Reproducible). VenomsBase will unify venom datasets, standardize terminology, and enable comparative analyses across species, facilitating novel toxin discovery and functional annotation. Key features of VenomsBase include user-friendly data submission modules with built-in validation, advanced cross-species analysis tools, and integration of multidisciplinary datasets spanning genomics, transcriptomics, proteomics, functional assays, and ecological metadata. A modular, cloud-based design will ensure scalability, while heuristic scoring systems will guide users toward high-confidence data entries. To promote accessibility, the envisioned VenomsBase will provide tutorials, regular training sessions, case studies, and feedback loops, supporting researchers at all levels. By harmonizing venom research and addressing the limitations of outdated or nonstandardized methods, VenomsBase aims to revolutionize the field, while being continuously improved and refined by venom experts. This initiative will unlock venoms' potential to make groundbreaking discoveries, address global health challenges, and foster collaboration and innovation across the scientific community.

Confrontations of the Pathogenic Fungus Colletotrichum graminicola With a Biocontrol Bacterium or a Ubiquitous Fungus Trigger Synthesis of Secondary Metabolites With Lead Structures of Synthetic Fungicides.

Environmental microbiology, 27(7):e70145.

Microbial biological control agents are increasingly used as an alternative to synthetic pesticides. The application of these microorganisms massively affects all members of plant-colonising microbial communities, including pathogenic fungi. In the majority of cases, the resulting competition for ecological niches is decided by the toxicity of microbial secondary metabolites (SMs) formed. In this study, we devised confrontation experiments employing the fungal maize pathogen Colletotrichum graminicola and antagonistic partners, that is the biocontrol bacterium Bacillus amyloliquefaciens and the ubiquitous ascomycete Aspergillus nidulans. Transcriptome studies uncovered strong de-regulation of the vast majority of the C. graminicola secondary metabolite biosynthetic gene clusters (SMBGCs), with 69% and 86% of these clusters de-regulated at confrontation sites with B. amyloliquefaciens or A. nidulans, respectively. In the biocontrol bacterium and in A. nidulans confronting the maize pathogen, 100% and 74% of the SMBGCs were transcriptionally de-regulated, respectively. Correspondingly, non-targeted high-resolution LC-MS/MS revealed a large repertoire of 1738 and 1466 novel features formed in the fungus-bacterium and fungus-fungus confrontation, respectively. Surprisingly, several of these belong to chemical classes with lead structures of synthetic fungicides.

Microbial genomic database of the Yangtze River, the third-longest river on Earth.

Scientific data, 12(1):1222.

Microbes play an important role in mediating the nutrient cycling in the river ecosystem as a hotspot for biogeochemical processes. Due to scattered sampling efforts, however, there is a lack of a systematic study of the diversity of prokaryotic genomes in the Yangtze River, the third longest river on Earth. Here, we collected 602 metagenomic datasets of water, sediment and riparian soil samples spanning the Upper, Middle, and Lower basins of the Yangtze River over a 6,300 km continuum. We reconstructed 8,110 qualified genomes represented by 927 species-level genomes at the 95% ANI threshold, spanning 31 bacterial and five archaeal phyla. We further showed that more than half of these species (61.3% ~ 82.4%) were novel according to the genomic comparison against the curated databases, greatly expanding the known diversity of river prokaryotes. This dataset depicts an overview of microbial genomic diversity in the Yangtze River and provides a resource for in-depth investigation of metabolic potential, ecology, and evolution of riverine microbiomes.

Trends over time in age-standardised prevalence of cardiometabolic risk factors in Senegal between 1975 and 2021 by sex: an ecological study from the WHO Inequality Data Repository.

BMJ open, 15(7):e101323.

OBJECTIVE: We aimed to analyse the time trends of cardiometabolic risk factors in Senegal from 1975 to 2021.

DESIGN: Ecological study of publicly available data from the WHO Health Inequality Data Repository.

SETTING: Disaggregated datasets from publicly available sources.

PRIMARY OUTCOME: Trends of age-standardised prevalence rates, stratified by sex for tobacco use, obesity, diabetes and hypertension, were analysed for significance.

PARTICIPANTS: Only data from Senegal were included in this study.

RESULTS: Tobacco use decreased in both sexes between 2000 and 2021, from 1.7% to 0.7% (p value 0.04) in females and from 28.1% to 12.8% (p value 0.04) in males. Obesity and overweight increased in both sexes between 1975 and 2016, from 14.2% to 35.9% (p value <0.001) in females and from 7.2% to 19.5% (p value<0.001) in males. Diabetes increased in both sexes between 1980 and 2014, from 4% to 7.3% (p value <0.001) in females and from 3.6% to 7.5% (p value <0.001) in males. Between 1990 and 2019, hypertension increased in females from 39.1% to 42.9% (p value <0.001). The prevalence of hypertension in males first rose from 37.5% to 40.0% (p value <0.001), then decreased to 37.3% (p value 0.013).

CONCLUSION: Our findings highlight changes in cardiometabolic risk factors in Senegal between 1975 and 2020 by sex. While tobacco use declined, rates of obesity, diabetes and hypertension increased. These findings underscore the need for strategies to mitigate this increase in cardiometabolic risk factors and a consequential rise in non-communicable diseases.

A major trade-off between growth and defense in Arabidopsis thaliana can vanish in field conditions.

PLoS biology, 23(7):e3003237.

When wild plants defend themselves from pathogens, this often comes with a trade-off: the same genes that protect a plant from disease can also reduce its growth and fecundity in the absence of pathogens. One protein implicated in a major growth-defense trade-off is ACCELERATED CELL DEATH 6 (ACD6), an ion channel that modulates salicylic acid (SA) synthesis to potentiate a wide range of defenses. Wild Arabidopsis thaliana populations maintain significant functional variation at the ACD6 locus, with some alleles making the protein hyperactive. In the greenhouse, plants with hyperactive ACD6 alleles are resistant to diverse pathogens, yet they are of smaller stature, their leaves senesce earlier, and they set fewer seeds compared to plants with the standard allele. We hypothesized that ACD6 hyperactivity would not only affect the growth of microbial pathogens but also more generally change leaf microbiome assembly. To test this in an ecologically meaningful context, we compared plants with hyperactive, standard, and defective ACD6 alleles in the same field-collected soil, both outdoors and in naturally lit and climate-controlled indoor conditions, taking advantage of near-isogenic lines as well as a natural accession and a CRISPR-edited derivative. We surveyed visual phenotypes, gene expression, hormone levels, seed production, and the microbiome in each environment. The genetic precision of CRISPR-edited plants allowed us to conclude that ACD6 genotype had no effect on mature field plants in our setting, despite reproducibly dramatic effects on greenhouse plants. We conclude that additional abiotic and/or microbial signals present outdoors-but not in the greenhouse-greatly modulate ACD6 activity. This raises the possibility that the fitness costs of other commonly studied immune system genes may be grossly misjudged without field studies.

Combination of spatial and temporal de-noising and artifact reduction techniques in multi-channel dry EEG.

Frontiers in neuroscience, 19:1576954.

INTRODUCTION: Dry electroencephalography (EEG) allows for recording cortical activity in ecological scenarios with a high channel count, but it is often more prone to artifacts as compared to gel-based EEG. Spatial harmonic analysis (SPHARA) and ICA-based methods (Fingerprint and ARCI) have been separately used in previous studies for dry EEG de-noising and physiological artifact reduction. Here, we investigate if the combination of these techniques further improves EEG signal quality. For this purpose, we also introduced an improved version of SPHARA.

METHODS: Dry 64-channel EEG was recorded from 11 healthy volunteers during a motor performance paradigm (left and right hand, feet, and tongue movements). EEG signals were denoised separately using Fingerprint + ARCI, SPHARA, a combination of these two methods, and a combination of these two methods including an improved SPHARA version. The improved version of SPHARA includes an additional zeroing of artifactual jumps in single channels before application of SPHARA. The EEG signal quality after application of each denoising method was calculated by means of standard deviation (SD), signal to noise ratio (SNR), and root mean square deviation (RMSD), and a generalized linear mixed effects (GLME) model was used to identify significant changes of these parameters and quantify the changes in the EEG signal quality.

RESULTS: The grand average values of SD improved from 9.76 (reference preprocessed EEG) to 8.28, 7.91, 6.72, and 6.15 μV for Fingerprint + ARCI, SPHARA, Fingerprint + ARCI + SPHARA, and Fingerprint + ARCI + improved SPHARA, respectively. Similarly, the RMSD values improved from 4.65 to 4.82, 6.32, and 6.90 μV, and the SNR values changed from 2.31 to 1.55, 4.08, and 5.56 dB.

DISCUSSION: Our results demonstrate the different performance aspects of Fingerprint + ARCI and SPHARA, artifact reduction and de-noising techniques that complement each other. We also demonstrated that a combination of these techniques yields superior performance in the reduction of artifacts and noise in dry EEG recordings, which can be extended to infant EEG and adult MEG applications.

An e-Reporting Tool for Facilitating Submission of Veterinary Adverse Drug Reaction Reports.

Journal of veterinary internal medicine, 39(4):e70173.

BACKGROUND: Adverse events (AEs) are under-reported in veterinary medicine. The ability to report AEs directly from the practice management system (PMS) has been suggested to facilitate reporting. The Small Animal Veterinary Surveillance Network (SAVSNET) informatics system provides an opportunity to integrate reporting into the workflow such that reports can be submitted directly to the National Competent Authority, the Veterinary Medicines Directorate (VMD).

OBJECTIVES: Develop an AE reporting form linked to the PMS allowing for pre-population of some fields from the electronic health record (EHR). Analyze the quality of submitted reports.

ANIMALS: Animals attending United Kingdom (UK) first-opinion veterinary practices participating in SAVSNET.

METHODS: An AE "reporting button" was developed and available in the normal clinical workflow for SAVSNET enrolled practices using the Robovet PMS. The button facilitated capture of pertinent information relating to AEs, including the ability to append clinical notes from the associated EHR. After submission, reports were automatically submitted daily to the VMD. Report quality was assessed using an adapted version of the vigiGrade scoring system, which was used to compare the quality of reports submitted to the VMD via standard routes to those submitted via SAVSNET. Assessment of reports submitted via SAVSNET, was conducted twice. First, considering only information contained in the report and second, considering information contained in both the report and associated clinical notes.

RESULTS: Sixty reports were submitted during the first 18 months by 42 different veterinary practices. The quality of SAVSNET reports was significantly improved by information contained within the clinical notes. These reports were more likely to be well-documented than those submitted via standard routes.

Adverse event reports populated using EHR data are well documented and can support efficient reporting of AEs in veterinary medicine.

Towards the Operationalization of Health Technology Sustainability Assessment and the Early Eco Design of the Internet of Medical Things.

Sensors (Basel, Switzerland), 25(13):.

An increasing number of scholars are raising concerns about the sustainability of digital health, calling for action to prevent its harmful effects on the environment. At this point, however, the comprehensive appraisal of emerging technology in the health sector remains theoretically challenging, and highly difficult to implement in practice and in ecological design. Indeed, background factors such as the rapid evolution of technology or effectiveness-efficiency tradeoffs complicate the task of distinguishing the benefits of digital health from its drawbacks, rendering early Health Technology Sustainability Assessment (HTSA) extremely complex. Within this context, the aim of this article is to draw attention to the pragmatism that should be adopted when anticipating the sustainability of technological innovation in the medical field, while simultaneously proposing an assessment framework grounded in a structural and conceptual dissection of the fundamental purpose of smart technologies and the Internet of Medical Things (IoMT). Building on this, we demonstrate how our framework can be strategically applied through a rapid back-of-the-envelope assessment of the economic and ecological balance when introducing IoMT prototypes for treating a specific condition, based on a preliminary simulation of a defined clinical outcome. In this manner, the article presents evidence that challenges two primary hypotheses, and also encourages reflection on the central role of information and its interpretation when addressing key barriers in the HTSA of digital health. Thereby, it contributes to advancing cost-benefit and cost-effectiveness evaluation tools that support eco design strategies and guide informed decision-making regarding the integration of sustainable IoMT systems into healthcare.

Selecting Sites for Strategic Surveillance of Zoonotic Pathogens: A Case Study in Panamá.

EcoHealth [Epub ahead of print].

Surveillance and monitoring of zoonotic pathogens is key to identifying and mitigating emerging public health threats. Surveillance is often designed to be taxonomically targeted or systematically dispersed across geography; however, those approaches may not represent the breadth of environments inhabited by a host, vector, or pathogen, leaving significant gaps in our understanding of pathogen dynamics in their natural reservoirs and environments. As a case study on the design of pathogen surveillance programs, we assess how well 20 years of small mammal surveys in Panamá sampled available environments and propose a multistep approach to selecting survey localities in the future. We use > 8000 georeferenced mammal specimen records, collected as part of a long-term hantavirus surveillance program, to test the completeness of country-wide environmental sampling. Despite 20 years of surveillance, our analyses identify a few key environmental sampling gaps. To refine surveillance strategies, we select a series of "core" historically sampled localities for continued surveillance, supplemented with additional environmentally distinct sites to more completely represent available environments in Panamá. Based on lessons learned through decades of surveillance, we propose a series of recommendations to improve strategic sampling of wildlife for zoonotic pathogen surveillance.

[Validation of satellite estimates for health interventions: use of microcensus data in Bolivia, 2024Validação de estimativas por satélite para intervenções de saúde: o uso de microcensos na Bolívia, 2024].

Revista panamericana de salud publica = Pan American journal of public health, 49:e71.

OBJECTIVE: To provide more accurate population estimates to support the operation of Bolivia's immunization program.

METHODS: This cross-sectional ecological study calculated population estimates using geospatial covariates extracted from Meta Data for Good and WorldPop satellite imagery, and validated them with the results of a microcensus conducted in five Bolivian municipalities.

RESULTS: Of the 6077 buildings identified in satellite images, 4505 residential buildings were found to be occupied. Of these, 3087 (68.52%) agreed to participate in the survey. A total of 17 617 people were expected and 13 397 were enumerated. Field enumeration identified fewer people under 30 years of age and more people over 60 years of age than expected. The Meta images provided excellent matches when analyzing population estimates by sex. Meta matched best with enumeration in rural areas, and WorldPop matched best with enumeration in urban areas.

CONCLUSIONS: This study demonstrates that combining geospatial analysis with microcensus validation can significantly improve health planning, enabling equitable resource distribution and more effective immunization coverage.

The impact of implementing the women's reproductive rights agenda on climate change.

Frontiers in global women's health, 6:1594066.

The 1994 International Conference on Population and Development (ICPD) established sexual and reproductive health and rights (SRHR) as foundational to sustainable development. Thirty years later, advancing women's reproductive rights (WRR), encompassing agency, decision-making autonomy, and universal access to family planning-remains critical not only for health and gender equity but also for mitigating environmental degradation. By reducing unintended pregnancies and empowering women to align childbearing with personal and ecological capacity, WRR alleviates ecological stressors such as deforestation while enhancing health resilience in climate-vulnerable communities. Yet, despite well-documented linkages between population dynamics and environmental change, contemporary climate policies and funding mechanisms persistently exclude WRR. This oversight undermines the potential of reproductive justice to enhance climate resilience. Additionally, claims that integrating WRR into climate agendas covertly promotes population control or represses women in low- and middle-income countries are fundamentally misleading. Crucially, research is needed to quantify the specific environmental impacts of WRR, underscoring the urgent need for robust global models to predict and validate these co-benefits. Strengthening this evidence base is imperative to inform policies that integrate WRR indicators into climate financing frameworks, ensuring gender-responsive programming. Bridging this gap requires interdisciplinary collaboration to develop metrics that capture WRR's role in reducing resource consumption and enhancing adaptive capacity. Embedding WRR within climate agendas would harmonize reproductive justice with environmental action, unlocking synergies between gender equity, health resilience, and sustainability. Fulfilling the ICPD's vision demands centering WRR in global climate strategies, thereby advancing a just and livable future for all.

Healthy at Home for COPD: An Integrated Digital Monitoring, Treatment, and Pulmonary Rehabilitation Intervention.

BMC digital health, 3:.

BACKGROUND: Chronic Obstructive Pulmonary Disease (COPD) is a leading cause of morbidity and mortality in the United States. Frequent exacerbations result in higher use of emergency services and hospitalizations, leading to poor patient outcomes and high costs. The objective of this study is to demonstrate the feasibility of a multimodal, community-based intervention in treating acute COPD exacerbations.

RESULTS: Over 18 months, 1,333 patients were approached and 100 (7.5%) were enrolled (mean age 66, 52% female). Ninety-six participants (96%) remained in the study for the full enrollment period. Fifty-five (55%) participated in tele-pulmonary-rehabilitation. Participants wore the smartwatch for a median of 114 days (IQR 30-210) and 18.9 hours/day (IQR16-20) resulting in a median of 1034 minutes/day (IQR 939-1133). The rate at which participants completed scheduled survey instruments ranged from 78-93%. Nearly all participants (85%) performed COPD ecological momentary assessment at least once with a median of 4.85 recordings during study participation. On average, a 2.48-point improvement (p=0.03) in COPD Assessment Test Score was observed from baseline to study completion. The adherence and symptom improvement metrics were not associated with baseline patient activation measures.

CONCLUSIONS: A multimodal intervention combining preventative care, symptom and biometric monitoring, and MIH services was feasible in adults living with COPD. Participants demonstrated high protocol fidelity and engagement and reported improved quality of life.

A Critical Reexamination of Recovered SARS-CoV-2 Sequencing Data.

Molecular biology and evolution, 42(6):.

In 2021, Jesse Bloom published a study addressing why the earliest SARS-CoV-2 sequences in Wuhan from late December 2019 were not those most similar to viruses sampled in bats. The study concluded that recovered partial sequences from Wuhan and annotation of Wuhan links for other sequences increased support for one genotype as the progenitor of the SARS-CoV-2 pandemic. However, we show that the collection date for the recovered sequences was January 30, 2020, later than that of hundreds of other SARS-CoV-2 sequences. Mutations in these sequences also exhibit diversity consistent with SARS-CoV-2 sequences collected in late January 2020. Furthermore, we found that Wuhan exposure history was common for early samples, so Bloom's annotation for a single familial cluster does not support that an early genotype was undersampled in Wuhan. Both the recovered partial sequences and additional annotation align with contemporaneous data rather than increase support for a progenitor. Our findings clarify the significance of the recovered sequences and are supported by additional data and analysis published since mid-2021.

Unraveling the Implications of Digit Bias in Digital Health - A Literature Review.

Internal medicine (Tokyo, Japan), 64(14):2090-2099.

Digital health, which encompasses digital medicine and therapy, integrates advanced technologies across healthcare. Central to this transformation is 'digitization,' which converts continuous analog data into a discrete digital form. However, this process is challenging. First, digitization inherently has the potential to introduce information loss, thereby diminishing the richness and complexity of data. Second, "digit bias," a cognitive distortion, emerges in the interpretation phase, where individuals' perceptions of and reactions to digital data are intrinsically skewed. There exist two major cognitive biases during digitization process: "digit preferences," where healthcare providers prioritize specific numbers, and "left digit bias" where continuous variables are disproportionately estimated by focusing on the leftmost digit. Although information loss and cognitive biases can cause significant distortions in healthcare, the effects of this "digitization" process have not been adequately quantified, and the accumulation of further evidence in this field is anticipated.

Single-cell mutational burden distributions in birth-death processes.

PLoS computational biology, 21(7):e1013241.

Genetic mutations are footprints of cancer evolution and reveal critical dynamic parameters of tumour growth, which otherwise are hard to measure in vivo. The mutation accumulation in tumour cell populations has been described by various statistics, such as site frequency spectra (SFS), single-cell division distributions (DD) and mutational burden distributions (MBD). While DD and SFS have been intensively studied in phylogenetics especially after the development of whole genome sequencing technology of bulk samples, MBD has drawn attention more recently with the single-cell sequencing data. Although those statistics all arise from the same somatic evolutionary process, an integrated understanding of these distributions is missing and requires novel mathematical tools to better inform the ecological and evolutionary dynamics of tumours. Here we introduce dynamical matrices to analyse and unite the SFS, DD and MBD and derive recurrence relations for the expectations of these three distributions. While we successfully recover classic exact results in pure-birth cases for the SFS and the DD through our new framework, we derive a new expression for the MBD and approximate all three distributions when death is introduced. We demonstrate a natural link between the SFS and the single-cell MBD, and show that the MBD can be regenerated through the DD. Counter-intuitively, the single-cell MBD is mainly driven by the stochasticity arising in the DD, rather than the extra stochasticity in the number of mutations at each cell division.

Single-Cell Transcriptomic Analysis Reveals Hair Cell-Specific Molecular Responses to Polystyrene Nanoplastics in a Zebrafish Embryo Model.

Biotechnology and applied biochemistry [Epub ahead of print].

Polystyrene nanoplastics (PSNPs) have emerged as pervasive environmental pollutants with potential toxicological effects on aquatic ecosystems. Their small size, hydrophobicity, and structural stability enable penetration into biological tissues, inducing diverse toxic responses. This study investigates the physiological and molecular impacts of PSNPs on zebrafish embryos using single-cell RNA sequencing and phenotypic analyses. While PS-NP exposure at environmentally relevant concentrations caused no significant changes in survival or overt phenotypes, it led to alterations in cell type proportions and gene expression. Differentially expressed gene (DEG) analysis revealed the upregulation of genes such as col1a1a, fgfbp2b, cytl1, and fstl1a, which were validated in vivo. These genes are associated with extracellular matrix remodeling, immune regulation, and tissue repair, suggesting that PSNPs activate defensive and reparative mechanisms in response to environmental stress. These findings highlight the molecular and cellular responses to PSNP exposure in zebrafish embryos and underscore the importance of evaluating the ecological risks posed by nanoplastics.

GeoAI-based soil erosion risk assessment in the Brahmaputra River Basin: a synergistic approach using RUSLE and advanced machine learning.

Environmental monitoring and assessment, 197(8):901 pii:10.1007/s10661-025-14314-w.

Soil erosion is a critical environmental issue in the Brahmaputra River Basin, threatening agricultural productivity, water resources, and ecological balance. This study employs the revised universal soil loss equation (RUSLE) alongside remote sensing, geographic information systems (GIS), and advanced machine learning models like random forest (RF) and gradient boosting (GB) to analyze soil erosion patterns from 2005 to 2024. The analysis revealed that average annual soil loss increased from 15.8 tons/ha/year in 2005 to 25.4 tons/ha/year in 2024, marking a 60.76% rise over two decades. Peak erosion rates were observed in 2020, with localized hotspots recording up to 32,130 tons/ha/year. Spatial analysis from 2005 to 2024 indicated substantial variability, with soil loss values ranging from - 7.024 to 9034 tons/ha in 2005. Topographic influence, quantified using the LS factor, revealed that 47.2% of the basin area has slopes steeper than 16°, significantly contributing to elevated erosion risk. The rainfall erosivity (R-factor) fluctuated throughout the period, peaking at 2305.73 MJ mm/ha h year in 2015 but declining to 799.21 MJ mm/ha h year by 2024, indicating a temporal shift in rainfall patterns. Vegetation cover improvements during this time reduced the mean C-factor from 0.52 to 0.34, though 13.8% of the basin (approximately 3.05 million ha) still falls under high to very high erosion risk zones. RF model predictions achieved an R[2] of 0.915 and RMSE of 4.82, while GB attained an R[2] of 0.952 with RMSE of 3.97, indicating superior predictive performance. These findings underscore the urgent need for targeted soil conservation measures, afforestation programs, and sustainable watershed management. The integration of AI-driven modeling with remote sensing and GIS provides a robust framework for long-term soil erosion monitoring, enabling informed decision-making for climate adaptation in the region.

Longitudinal sequencing of cardiometabolic multimorbidity among older adults and association with subsequent dementia onset.

PloS one, 20(7):e0326309.

BACKGROUND: Patterns of development of cardiometabolic multimorbidity (CMM) and the impact of specific cardiometabolic disease combinations on cognitive function are not well understood. This study utilizes sequence analysis to describe the ordering and timing of cardiometabolic disease accumulation over a five-year period and to assess both sociodemographic predictors and cognitive outcomes of typical cardiometabolic disease sequences.

METHODS: We analyzed data from the National Health and Aging Trends Study (2011-2022), including respondents aged ≥65 years without CMM or cognitive impairment at baseline (N = 4956). We used sequence analysis with optimal matching and hierarchical cluster analysis to describe temporal patterns of cardiometabolic disease accumulation and to construct a typology by clustering similar sequences. Sociodemographic predictors of CMM cluster membership were assessed using multinomial logistic regression and discrete time survival analysis was used to examine the association of CMM clusters with subsequent dementia development.

RESULTS: 11.8% of respondents developed CMM within 5-years. From a total of 366 distinct cardiometabolic disease sequences, we identified eight cardiometabolic sequence clusters. The first five clusters, "No Cardiometabolic Disease" (N = 2283, 46.1%); "Diabetes Only" (N=642, 13.0%); Heart Disease Only" (N = 297, 6.0%); "MI Only" (N = 145, 2.9%); "Stroke Only" (N = 132, 2.7%), were composed of persons who did not develop CMM over the observation period. The sixth cluster, "Incident CVD with Multimorbidity" (N = 656, 13.2%), was largely composed of persons with no conditions at baseline who developed incident cardiometabolic disease and/or CMM during the observation period (N = 477, 72.7%) and the seventh cluster, "Diabetes Multimorbidity" (N = 333, 6.7%), primarily consisted of persons with diabetes who developed incident CMM. Finally, the eight cluster (N = 468, 9.4%) was characterized by mortality early in the observation period with minimal CMM development during the observation period. Black and Hispanic race/ethnicity, lower wealth, and obesity were associated with increased likelihood of membership in one or both of the clusters characterized by CMM development. We observed increased dementia risk among persons in the Incident CVD with Multimorbidity cluster (HR = 1.32, 95% CI = 1.04-1.67) and the Diabetes MM cluster (HR = 1.88, 95% CI = 1.44,2.44).

CONCLUSIONS: Development of cardiometabolic multimorbidity is more likely among minoritized and/or low-income older adults and is associated with increased risk of subsequent dementia. Targeted approaches to cardiometabolic disease prevention and risk reduction may be an effective means of slowing or preventing the onset of cognitive decline among these groups.

High-Resolution GPS Tracking of Perch-Hunting Bats, Rhinolophus nippon, during Nightly Foraging Behavior.

Zoological science, 42(3):249-259.

While the echolocation behavior and specialized adaptive auditory system of the greater horseshoe bat (Rhinolophus ferrumequinum) are well documented, comprehensive insights into its wild ecology, especially its detailed nocturnal movements for foraging behavior, remain scarce. Therefore, our objective was to obtain information on the spatiotemporal features of the movements of the Japanese greater horseshoe bat (Rhinolophus nippon), a close relative of R. ferrumequinum, during foraging. Hence, we investigated the nightly flight paths of R. nippon using high-resolution GPS data loggers. Initially, hidden Markov modeling analysis classified bat flight paths into two behavioral patterns: commuting and area-restricted behavior, the latter primarily corresponding to foraging activities. Focusing on foraging behavior along their trajectory, we observed that R. nippon repeatedly foraged with brief stops lasting only a few minutes and an average distance of approximately 300 m between any two foraging sites. Notably, one individual covered a considerable distance (23.6 km) from its roost, possibly because of irregular social behavior during the mating season. Furthermore, for commuting, bats occasionally used forest roads, which were located along the middle of relatively steep slopes. In cases of echolocations with limited detection distances, echoes from the ground and adjacent tree lines offered crucial navigation cues, underscoring the significance of forest roads as nightly movement routes for echolocating bats. Overall, our findings highlight the importance and urgency of ongoing research on bat movement ecology in Japan.

A two-level approach to geospatial identification of optimal pitaya cultivation sites using multi-criteria decision analysis.

Journal of the science of food and agriculture, 105(11):5851-5862.

BACKGROUND: Pitaya, also known as dragon fruit, is one of the most popular and expensive fruits in the world. It has been commercially produced since the early 20th century. This plant requires a specific growing environment and ecological conditions, so it is typically cultivated under greenhouse conditions in Türkiye. However, there is a clear need for a comprehensive assessment of outdoor adaptation and/or outdoor growing areas for sustainable yield at the regional scale.

RESULTS: This study presents a multi-criteria decision-making analysis-based geographical information system (GIS) study to identify and evaluate the suitability of outdoor growing areas for pitaya. In this study, eight crucial factors were identified for outdoor pitaya cultivation: temperature, rainfall, soil pH, soil depth, land use capability, altitude, slope and aspect. An analytical hierarchy process was conducted to determine the weights for each parameter, followed by a weighted overlay analysis using GIS tools. The range of weight values was obtained between 0.2748 and 0.0319. The area of the best places for pitaya cultivation was calculated to be 9245.7 ha (11.7%). It was determined that 32.63%, 37.57% and 18.1% of the locations were moderately suitable, less appropriate and unsuitable, respectively.

CONCLUSION: The selection of comparable production sites will be guided by the study. Such suitable site selection studies are extremely significant since the cultivation of the pitaya plant, which has a high commercial value for economically developing countries, will be crucial to the growth of agricultural employment in these nations. Future research will be guided by this study's methodology and analysis strategies. © 2025 Society of Chemical Industry.

Control of toxicity of fine particulate matter emissions in China.

Nature, 643(8071):404-411.

Fine particulate matter (particulate matter with a diameter of 2.5 μm or less; PM2.5) causes millions of premature deaths globally[1], but not all particles are equally harmful[2-4]. Current air-pollution control strategies, prioritizing PM2.5 mass reduction, have provided considerable health benefits but further refinements based on differences in the toxicity of various emission sources may provide greater benefits[5-7]. Here we integrated field measurements with air-quality modelling to assess the unequal toxicities of PM2.5 from various anthropogenic sources. Our findings revealed that the toxicity per unit of PM2.5 mass differed substantially between major sources, differing by up to two orders of magnitude. PM2.5 from solid fuel combustion in residential stoves had the highest toxicity, followed by those from the metallurgy industry, brake wear, diesel vehicles, petrol vehicles, the cement industry and power plants. We further analysed the source contributions of toxicity-adjusted PM2.5 emissions and population exposures in China. From 2005 to 2021, both the PM2.5 mass and relative-potency-adjusted emissions substantially decreased. Although industrial sources contributed 57.5% to the reduction in PM2.5 mass emissions, the reduction in relative potency-adjusted emissions was driven by residential combustion (approximately 80%). Clean-air policies should consider the differing toxicities of PM2.5 when formulating source-specific emission control regulations. This study proposes a cellular toxicity-based framework for PM2.5 reduction that could address the specific health risks in diverse regions, but further epidemiological studies will be required to confirm their relevance to human health outcomes and their application to public policy.

Evolution of foraging behaviour induces variable complexity-stability relationships in mutualist-exploiter-predator communities.

PLoS computational biology, 21(7):e1013245.

Early ecological theory predicts that complex ecological networks are unstable and are unlikely to persist, despite many empirical studies of such complexity in nature. This inconsistency has fascinated ecologists for decades. To resolve the complexity-stability debate, coupling population dynamics and trait dynamics is considered to be an important way to understand the long-term stability of ecological community assemblages. However, we still do not know how eco-evolutionary feedbacks affect the relationship between complexity and stability in ecologically realistic networks with both antagonistic and mutualistic interactions. Here, we explored an adaptive network model to evaluate how the evolution of foraging preference to determine the relationship between network complexity (i.e., connectance) and stability (i.e., community persistence at steady state) in mutualist-exploiter-predator communities (MEST). Our theoretical results showed: (i) adaptive foraging of the top predator contributes to the stability of mutualism and intermediate intensity of foraging adaptations can lead to chaotic dynamics in a four-species MEST community; (ii) the complexity-stability relationship may show positive monotonic, negative monotonic, peaked and double-peaked patterns in general MEST communities, while the double-peaked pattern is only obtained when both the adaptation intensity and interspecific competition are high. Furthermore, model predictions may be consistent with both the negative monotonic pattern revealed in freshwater communities and the peaked pattern revealed in marine communities. Finally, we infer that foraging adaptations of the top predator may alter positive or/and negative feedback loops (trait-mediated indirect effects) to affect the stability of general MEST communities. Our adaptive network framework may provide an effective way to address the complexity-stability debate in real ecosystems.

Identifying the Climate Conditions Associated With Extreme Growth States in Trees Across the Western United States.

Global change biology, 31(7):e70317.

Climate extremes-e.g., drought, atmospheric rivers, heat waves-are increasing in severity and frequency across the western United States of America (USA). Tree-ring widths reflect the concurrent and legacy effects of such climate extremes, yet our ability to predict extreme tree growth is often poor. Could tree-ring data themselves identify the most important climate variables driving extreme low- and high-growth states? How does the importance of these climate drivers differ across species and time? To address these questions, we explored the spatial synchrony of extreme low- and high-growth years, the symmetry of climate effects on the probability of low- and high-growth years, and how climate drivers of extreme growth vary across tree species. We compiled ring widths for seven species (four gymnosperms and three angiosperms) from 604 sites in the western USA and classified each annual ring as representing extreme low, extreme high, or nominal growth. We used classification random forest (RF) models to evaluate the importance of 30 seasonal climate variables for predicting extreme growth, including precipitation, temperature, and vapor pressure deficit (VPD) during and up to four years prior to ring formation. For four species (three gymnosperms, one angiosperm) for which climate was predictive of growth, the RF models correctly classified 89%-98% and 80%-95% of low- and high-growth years, respectively. For these species, asymmetric climate responses dominated. Current-year winter hydroclimate (precipitation and VPD) was most important for predicting low growth, but prediction of high growth required multiple years of favorable moisture conditions, and the occurrence of low-growth years was more synchronous across space than high-growth years. Summer climate and temperature (regardless of season) were only weakly predictive of growth extremes. Our results motivate ecologically relevant definitions of drought such that current winter moisture stress exerts a dominant role in governing growth reductions in multiple tree species broadly distributed across the western USA.

DNA profile database of Koompassia malaccensis in Malaysia and its application in forensic investigation.

Scientific reports, 15(1):24504.

DNA profiling has been an important tool in human forensic for almost four decades, revolutionising criminal investigations. In recent years, it has also been utilised in timber identification and geographical traceability of stolen logs, with notable increase in forensic DNA analysis related to forest crimes, driven by the growing concerns over illegal logging and forest conservation. In this study, DNA profile database for a tropical timber species, Koompassia malaccensis was established, with a total of 1465 samples from 56 locations across Malaysia genotyped using nine short tandem repeat (STR) markers. Based on the results of cluster analyses, the STR database was partitioned into WM (West Malaysia), EM (East Malaysia) and PS (Peat Swamp) Database. Thereafter, each regional/ecological database was characterised for forensic parameters and allele frequencies. Due to weak population differentiation, the percentage of individuals correctly assigned to the population of origin was low. However, the assignment tests to the region of origin were highly accurate (mean = 99.6%). The STR database is robust and has been used to assist the enforcement agencies in the investigation of forest crimes involving K. malaccensis. A case study is presented to demonstrate its application for individual identification in forensic context.

Impact of Symptoms of Late-Onset Hypogonadism as a Potential Driver of Presenteeism.

American journal of men's health, 19(4):15579883251343972.

Presenteeism, defined as attending work despite physical or mental health issues that impair full productivity, is a prevalent concern with significant implications for workplace efficiency and employee well-being. Testosterone, the primary male sex hormone, plays a vital role in sustaining physical energy, cognitive function, and emotional stability-key factors for optimal work performance. This study explores the association between late-onset hypogonadism (LOH) and presenteeism, emphasizing how LOH-related symptoms such as fatigue, reduced libido, erectile dysfunction, and mood disturbances may contribute to reduced workplace productivity. Data from 96 male patients aged 27 to 76 years, who sought treatment at a university hospital for LOH-related symptoms, were analyzed using blood tests and validated questionnaires, including the Aging Males' Symptoms (AMS) scale, Work Functioning Impairment Scale (WFun), and Sexual Health Inventory for Men. Significant correlations were observed between AMS scores and both work functioning impairment and erectile dysfunction, indicating a strong link between LOH symptoms and presenteeism. In addition, symptoms such as fatigue, diminished motivation, and poor sleep quality were identified as exacerbating factors for work-related impairments. The greatest strength of this study lies in its focus on clinically diagnosed LOH patients, a factor that significantly distinguishes it from prior research on presenteeism in general working populations. This study underscores the potential benefits of testosterone replacement therapy, lifestyle modifications, and workplace wellness programs in addressing presenteeism among employees with LOH. Further research is necessary to assess the efficacy of these interventions in mitigating presenteeism and improving employee well-being.

Multi-omics analyses provide insights into the molecular basis for salt tolerance of Phyla nodiflora.

The Plant journal : for cell and molecular biology, 123(1):e70325.

The perennial herbaceous plant, Phyla nodiflora (Verbenaceae), which possesses natural resistance to multiple abiotic stresses, is widely used as a pioneer species in island ecological restoration. Due to the lack of information about its genome, the mechanism underlying its tolerance to environmental stresses, such as salinity, is almost entirely unknown. Here, we report on the high-quality genome of P. nodiflora that is 403.07 Mb in size, and which was assembled and anchored onto 18 pseudo-chromosomes. Genomic synteny revealed that P. nodiflora underwent two whole genome duplication events, which promoted the expansion of genes related to environmental adaptation and the biosynthesis of secondary metabolites. An integrated genomic and transcriptomic analysis suggested that salt stress tolerance in P. nodiflora is associated with the expansion and activated expression of genes related to abscisic acid (ABA) homeostasis and signaling. The expansion of ZEP family genes may contribute to the consistent increase in ABA levels under salt stress. Lysine acetylomic analysis revealed that exposure to salt led to widespread protein deacetylation, with these proteins primarily involved in signal transduction, carbohydrate transport and metabolism, and transcription regulation. Deacetylation of glutathione S-transferase increased enzymatic activities in response to salt-induced oxidative stress. Collectively, the genomic, transcriptomic, and lysine acetylomic analyses provide profound insight into the molecular basis of the adaptation of P. nodiflora to salt stress, and will be helpful to engineer salt-tolerant plants for ecological restoration.

Microbiome and metabolome association network analysis identifies Clostridium_sensu_stricto_1 as a stronger keystone genus candidate than Bifidobacterium in the gut of common marmosets.

mSystems [Epub ahead of print].

The common marmoset (Callithrix jacchus), a nonhuman primate species, is a model organism of great interest due to its translational value in a variety of research settings, including the field of microbiomics. While the composition of the marmoset's gut microbiome has been somewhat described in captivity, little is known about how gut microbiota interact with each other over time and how they relate to metabolite production. To help answer this, we characterized interactions in the gut microbiome of the common marmoset by calculating the Spearman correlation coefficient between 16S rDNA-derived relative genera abundance data and targeted metabolomics data collected longitudinally from 10 captive marmosets. Association network graphs were used to visualize significant correlations and identify genera and metabolites that have high degree centrality, marking them as more influential within the microbiome. The genus Clostridium_sensu_stricto_1 engaged in the most metabolomic associations, indicating that it potentially plays a gatekeeping role over metabolites involved in microbial growth and signaling. Its associations with downregulated taurine and bile acids further suggest Clostridium_sensu_stricto_1 modifies bile acids to exert its influence. Flavonifractor and several Bacteroidales members had the most bacterial associations and were negatively associated with Bifidobacterium, indicating a potential competitive relationship. To further characterize microbiome interactions, we performed hierarchical clustering on significant within-dataset associations and developed a new "Keystone Candidate Score" metric that identified Clostridium_sensu_stricto_1 and Alloprevotella as the most influential bacteria (so-called candidate keystone genera) in the marmoset gut microbiome.IMPORTANCEPrevious studies have identified significant individuality within the gut microbiome of common marmosets. The reasons for this inter-subject variability and how it relates to health in captivity are poorly understood, owing to a lack of knowledge regarding dynamic interactions between specific microbiota. To that end, this study characterized significant temporal associations between the gut microbiome and metabolome of healthy captive marmosets. Our findings suggest that certain microbial taxa exert a stronger influence within the gut than others. Specifically, Bifidobacterium was the most abundant genus and primary driving force behind subject-specific microbiome differences, while Clostridium_sensu_stricto_1 and bacteria from the order Bacteroidales were the main sources, respectively, for significant bacteria-metabolite and bacteria-bacteria associations. Together, this suggests that Bifidobacterium may compete with the other taxa for resources and a metabolic niche in the marmoset microbiome.

Development of blood-brain barrier-penetrating antibodies for neutralizing tick-borne encephalitis virus in the brain.

mSphere [Epub ahead of print].

UNLABELLED: Tick-borne encephalitis virus (TBEV) belongs to the genus Flavivirus and causes tick-borne encephalitis (TBE), a disease characterized by severe neurological symptoms with a high mortality rate. Currently, no specific antiviral treatments have been developed for TBE. The blood-brain barrier (BBB) restricts drug delivery to the central nervous system, posing a major challenge in developing effective therapies targeting TBEV in the brain. In this study, we developed recombinant anti-TBEV antibodies fused with BBB-penetrating rabies virus glycoprotein (RVG) peptides to facilitate their transport across the BBB. The fusion of RVG peptides to the C-terminus of the heavy chain of whole antibodies or single-chain variable fragment had minimal impact on their neutralizing ability against TBEV. The RVG fusion enhanced antibody binding to the surface of a human brain endothelial cell line and increased permeability in an in vitro BBB model. The RVG-fused antibodies exhibited a higher transport efficiency to the brain than the non-fused antibodies following peripheral injection in mice. Notably, the peripheral administration of the RVG-fused whole antibody after viral invasion into the brain significantly neutralized TBEV in the brains of infected mice. These findings suggest that RVG-fused antibodies represent a promising therapeutic strategy for treating TBE once the virus has entered the brain.

IMPORTANCE: Tick-borne encephalitis virus is a neuroinvasive pathogen that causes severe neurologic disease, significantly affecting patients' quality of life. No specific antiviral treatment is available for tick-borne encephalitis caused by virus multiplication in the brain. The delivery of drugs to the brain via peripheral administration is often obstructed by the blood-brain barrier. To develop targeted antiviral therapies for brain infections, we engineered recombinant antibodies capable of crossing the blood-brain barrier via brain-targeted ligands. These antibodies exhibited permeability across the blood-brain barrier in both in vitro and in vivo models and notably effectively neutralized the virus within the brain following peripheral administration. This study is the first to highlight the therapeutic potential of brain-targeted recombinant antibodies after viral entry into the brain, offering a promising pathway for the development of effective antiviral treatments for tick-borne encephalitis.

Integrating multi-omics analysis unveils the key mechanisms of PQS-enhanced Algicidal activity in Enterobacter hormaechei F2.

Genomics, 117(4):111060.

Quorum sensing, as a pivotal bacterial signaling pathway, exhibits substantial potential for regulating algicidal activity. This study pioneers the integration of multi-omics analyses (transcriptomics, proteomics, metabolomics) with phenotypic profiling to systematically unravel the molecular mechanisms underlying Pseudomonas Quinolone Signal (2-heptyl-3-hydroxy-4(1H)-quinolinone, PQS)-enhanced algicidal activity in Enterobacter hormaechei F2. Co-cultivation with PQS triggered marked reductions in algal biomass and chlorophyll-a levels, outperforming traditional approaches. Fourier-transform infrared spectroscopy (FTIR) revealed PQS-induced metabolic disruption and membrane degradation in algal cells. Transcriptomic profiling identified novel regulatory hubs, including upregulated glycolysis (tktA, transketolase), fatty acid degradation (fadE, acyl-CoA dehydrogenase), and chemotaxis (malE, maltose-binding protein) pathways. Proteomics confirmed PQS-driven enrichment of terpenoid precursors, notably DXS synthase (1-deoxy-D-xylulose-5-phosphate synthase), and quorum sensing effectors. Metabolomics highlighted amino acid derivatives (e.g., L-glutamate) and heterocyclic antibiotics as dominant algicidal metabolites. Crucially, multi-omics integration delineated a core network of 46 key nodes (e.g., ribose transporter rbsB, L-glutamate) coordinating energy metabolism, motility, and algicide synthesis. Fatty acid degradation enzymes (e.g., FadE) and flagellar assembly regulators (e.g., FlgK) emerged as previously unrecognized targets, with PQS significantly enhancing bacterial swarming motility (p < 0.01) and biofilm formation. These findings establish the first mechanistic framework linking PQS signaling to algicidal process, demonstrating its role in synchronizing metabolic flux toward terpenoid synthesis while optimizing bacterial-algal interactions. Key pathways-including chemotaxis (malE) and terpenoid biosynthesis (DXS synthase)-provide actionable targets for engineering bioaugmented consortia or precision algicidal formulations. This work advances quorum sensing-driven strategies for sustainable harmful algal bloom (HAB) mitigation, offering scalable solutions for aquaculture and eutrophic water remediation with minimal ecological disruption. By bridging molecular mechanisms to field applications, the study underscores the translational potential of this approach in global water security initiatives.

Majority illusion drives the spontaneous emergence of alternative states in common-pool resource games with network-based information.

iScience, 28(7):112831.

Common-pool resources (CPRs), including fisheries and the atmosphere, are critical for ecological, social, and economic sustainability but are easily overused. We use an agent-based model to investigate how social networks shape resource extraction outcomes. Networks with highly visible nodes can create a "majority illusion" in which most users believe high-intensity extraction is dominant, even if it is not. This misperception can push the entire population toward one of two possible states: an abundant, high-welfare resource or a depleted, low-welfare one. Aligning users' environmental impact with their visibility can mitigate this effect and steer the system toward a single, predictable outcome. These results suggest that network-based policies, such as reshaping information flows, particularly targeting high-impact hubs, could help stabilize cooperative behaviors and encourage sustainable management of CPRs, reducing the risk of tragedy-of-the-commons scenarios.

Assessment of soil and groundwater pollution risks from coal gangue backfilling: A case study in Inner Mongolia mining areas.

Environmental research, 285(Pt 1):122303 pii:S0013-9351(25)01554-3 [Epub ahead of print].

This study evaluates the environmental risks of coal gangue (CG) filling through leaching experiments and numerical simulation methods. The results show that under acidic conditions, the leaching concentration of heavy metals in CG is relatively high, with copper concentration reaching 0.80 mg/L, exceeding Class I discharge standards. Under neutral conditions, the leachate indicators meet national standards. Although the reclaimed soil meets the agricultural land standards, its fertility level is relatively low (soil quality index 0.416), and cadmium, due to its high toxicity coefficient, becomes the primary ecological risk factor. The use of a layered compaction process can effectively control the migration of leachate. Numerical simulations indicate that the maximum migration depth of pollutants is 17 m, with concentrations stabilizing after 2500 days. The high mineralization of groundwater is primarily influenced by the geological background values, and the fluoride contamination plume has a diffusion range of less than 204 m. The study suggests that engineered CG filling reclamation presents controllable environmental risks and resource utilization potential. However, it is important to note that the study has limitations, such as a short monitoring period and uncertainties in the model predictions. It is recommended to conduct long-term field monitoring to comprehensively assess the environmental impact.

Innovative engineering of red-emissive carbon dots for profoundly sensitive and recyclable determination of malachite green in fish tissue.

Spectrochimica acta. Part A, Molecular and biomolecular spectroscopy, 344(Pt 1):126631 pii:S1386-1425(25)00938-2 [Epub ahead of print].

Accurate measurement of hazardous synthetic dye is highly attractive for environmental and food safety inspection. Herein, red fluorescent carbon dots (R-CDs) are meticulously engineered by employing Azure A as a fluorophore to optimize the optical characteristics, thereby promoting high-efficiency fluorescence emission at 648 nm. The constructed R-CDs demonstrate excitation-independent characteristics remarkable photostability and superior water solubility. It is encouraging that the developed R-CDs demonstrate a specific response to MG, effectively differentiating it from other substances. The engineered R-CDs demonstrate concentration-responsive fluorescence quenching towards MG, exhibiting rapid response time with a well-defined linear detection range of 0.09-8.21 μM and ultralow detection limit of 24.2 nM. Furthermore, the spike recovery analysis of MG in fish tissue demonstrated robust performance with recoveries of 97.63-106.0 % (RSD <6.37 %), highlighting the analytical reliability for MG identification in aquatic products. The aforementioned results underscore the significant potential of the developed R-CDs for MG detection in aquatic products and bolster their application in food safety inspections.

Predicting subjective sleepiness during auditory cognitive testing using voice signaling analysis.

Sleep science and practice, 9(1):19.

BACKGROUND: To determine whether objective markers of sleepiness can be collected passively using voice data to detect sleepiness in individuals undergoing testing in situations where sleepiness is not the focal point of assessment. We assessed verbal reaction time (VRT) as a vocalic marker of subjective sleepiness in middle aged and older adults with history of insomnia and benzodiazepine-receptor-agonist (BZRA) use.

METHODS: Adults aged ≥55 without a diagnosis of dementia were recruited from a BZRA deprescribing clinical trial and enrolled in the present study that tested the feasibility of cognitive testing using out-of-office, self-directed mobile apps. Participants' working/episodic memory were assessed through recorded verbal responses to Verbal Paired Associates (VPA) tests, and ecological momentary assessments (EMA) of self-reported sleepiness (1[not at all] to 4[more prominent]). Using a generalized additive model, we examined the association between VRT during VPA testing and self-reported sleepiness, adjusting for demographic, test parameters, caffeine intake, cognition, mood, and BZRA-use (p≤0.05 was considered significant). A stratified k-fold cross-validation/random forest (SKCV/RF) was performed to classify sleepiness levels, adjusting for other variables.

RESULTS: We analyzed 1,513 observations from 16 patients. VRT was operationalized as the time duration between recording start time and first speech epoch. Longer VRTs were positively associated with greater EMA sleepiness (p≤0.05). The SKCV/RF model yielded a mean F1-score of 0.80 ± 0.08 across folds.

CONCLUSIONS: Longer VRTs correlated with greater self-reported sleepiness, indicating that voice data can be used as a marker of sleepiness in patients undergoing cognitive testing in out-of-office settings.

Herbivore community function shapes resilience and bistability of coral reefs.

PLoS computational biology, 21(7):e1013221.

Ecological communities globally are shifting to degraded states, motivating research into attributes supporting resilience or leading to alternative stable states. Coral reef communities are particularly vulnerable as they are facing myriad anthropogenic impacts that contribute to shifts away from coral dominance, motivating much research on whether these shifts are gradual and reversible transitions versus alternative stable states. Empirical studies demonstrate functionally-diverse herbivorous fish communities support coral reef resilience to anthropogenic impacts. However, few coral reef models incorporate herbivore and algal functional groups and quantify their effects on reef resilience and alternative stable states. We built a coral reef model that includes herbivorous fish functional groups and their algal targets and explored how this expansion affects predictions of resilience and alternative stable states under different scenarios of human impacts. We found evenness across the functional groups of herbivores is increasingly important for reef recovery as fishing pressure increases, and recovery is promoted when algal communities begin with more turf than macroalgae. Our findings also highlight that models omitting functional groups that comprise real communities will miss crucial phenomena, such as loss of alternative stable states for browser-dominated communities, or continued presence of alternative stable states in grazer-dominated communities even when fishing pressure is removed entirely. This work advances our ability to understand and predict coral reef resilience and alternative stable states in the Anthropocene, and provides guidance for conservation policy on fishing practices.

Study on the synergies and trade-offs of sectoral water use and their relationship with economic development.

PloS one, 20(7):e0327626.

Water scarcity is dynamic and complex, beyond geophysical stressors and responses, it is critical to also consider how multi-sector, multiscale economic teleconnections mitigate or exacerbate water shortages. This study analyzes the spatial and temporal characteristics of Water Footprint (WF) in China from 2005 to 2022 and their relationship with economic development. The findings reveal an overall increase in China's WF, with the fastest growth observed in the Northwest and Northeast regions. Notably, Heilongjiang, Inner Mongolia, and Xinjiang experienced significant increases, while Zhejiang, Beijing, and Chongqing saw declines. Agricultural water footprint (WFargi) account for the largest share, while industrial water footprint (WFindu) show a decreasing trend, indicating improved water-use efficiency in industry. However, the rise in contamination water footprint (WFcont) and significant spatial disparities in import water footprint (WFimport) and export water footprint (WFexport) highlight the challenges in water resources management. Across different regions, there is a strong synergy between agricultural and ecological water use, while a notable trade-offs exists between industrial and agricultural water use, particularly in the Northeast. The relationship between WF consumption and economic development in China exhibits a phased pattern. From 2011 to 2016, most regions achieved strong decoupling, but from 2017 to 2022, all regions reverted to weak decoupling. This study provides new insights into the relationship between sectoral water use and economic development at regional and provincial levels, contributing to efforts to alleviate water scarcity, enhance water resources management, and promote sustainable economic development.

Revealing the Coupling Coordination Mechanisms between Carbon Efficiency and Carbon Equity: The Evidence in China's Interprovincial Trade.

Environmental science & technology [Epub ahead of print].

Effectively balancing carbon efficiency and carbon equity is vital for China's carbon peaking and carbon neutrality goals; however, the relationship between them remains unclear. This study first reveals the coupling coordination mechanisms between carbon efficiency and carbon equity based on Chinese provincial data from 2012 to 2017. We demonstrated that the carbon efficiency and carbon equity exhibited a strong coupling coordination relation (CCR). Carbon efficiency significantly promoted carbon equity and was a major driver of the CCR. With every 1 unit increase in carbon efficiency, carbon equity and the CCR increased by 3.766 to 5.694 units and approximately 1-2 units, respectively, and the positive impact of carbon efficiency on the CCR was approximately 6 to 8 times that of carbon equity. Carbon efficiency, carbon equity, and the CCR worsened between 2012 and 2017, and the bottom 50% of them were mainly concentrated in central and western provinces with abundant natural resources and net inflow of embodied carbon emission. Additionally, we demonstrated that resource dependence hindered carbon efficiency, carbon equity, and the CCR, and the potential transmission pathways were the crowding-out effect on the technology innovation, digital informatization, and advancement of industrial structure.

A review of engraftment assessments following fecal microbiota transplant.

Gut microbes, 17(1):2525478.

Fecal Microbiota Transplant (FMT) is a treatment for recurrent Clostridium difficile infections and is being explored for other clinical applications, from alleviating digestive and neurological disorders, to restoring microbiomes impacted by cancer treatment. Quantifying the extent of engraftment following an FMT is important in understanding a recipient's response to treatment. Engraftment and clinical response need to be investigated independently to evaluate an FMT's role (or lack thereof) in achieving a clinical response. Standardized bioinformatics methodologies for quantifying engraftment extent would not only improve assessment and understanding of FMT outcomes, but also facilitate comparison of FMT results and protocols across studies. Here we review FMT studies, integrating three concepts from microbial ecology as framework to discuss how these studies approached assessing engraftment extent: 1) Community Coalescence investigates microbiome shifts following FMT engraftment, 2) Indicator Features tracks specific microbiome features as a signal of engraftment, and 3) Resilience examines how resistant post-FMT recipients' microbiomes are to reverting back to baseline. These concepts explore subtly different questions about the microbiome following FMT. Taken together, they provide holistic insight into how an FMT alters a recipient's microbiome composition and provide a clear framework for quantifying and communicating about microbiome engraftment.

The effect of fear and compassion on human willingness to protect predators and prey.

Scientific reports, 15(1):23278.

Human perception of predators is extremely important because the decline in biodiversity requires greater involvement from the public in species conservation. We conducted an online study in Slovakia with 225 adult participants (151 women; mean age = 24 years), who viewed a series of short videos depicting predator-prey interactions in which the predator either won or lost the encounter. Most of the predators depicted were large mammals (e.g., leopards, lions), one of which was a snake. We examined participants' compassion towards both the predator and prey and their willingness to protect these species. Participants exhibited greater compassion towards predators when they lost, whereas prey received higher compassion scores when they lost than when they won. Prey generally received higher compassion scores than predators. Fear of perceived animals was negatively correlated with compassion for predators and prey. Perceived fear and compassion for both predators and prey were positively correlated with the willingness to protect them (WTP), although these correlations were negative for the majority of predator species. WTP was not significantly influenced by the outcome of the encounter. Snakes, often considered prototypical stimuli for human fear, elicited less compassion and lower WTP compared to mammalian predators. We conclude that human sensitivity to physical interactions between predators and prey does not necessarily translate into a willingness to protect these animals. Conservation strategies need to consider the emotional and cognitive biases people hold toward different species. By acknowledging these biases, especially fear and perceived charisma, conservation campaigns may more effectively foster public support for protecting a broader range of species.

6PPD and 6PPD-Q Inhibit Macrophyte Photosynthesis by Targeting Photosynthetic Antenna: Multiomics and Computational Modeling Insights.

Environmental science & technology, 59(26):13216-13226.

Emerging evidence indicates that N-(1,3-dimethylbutyl)-N'-phenyl-p-phenylenediamine (6PPD) and its derivative 6PPD-quinone (6PPD-Q) exert photosynthetic toxicity on aquatic macrophytes. However, their precise inhibitory mechanisms and toxic targets within the photosynthetic pathways remain poorly understood. Through a combination of physio-biochemical indicators, multiomics analysis, and molecular docking simulation, this study systematically explored the photosynthetic toxic effects of 6PPD and 6PPD-Q on Ceratophyllum demersum L. (C. demersum). Transcriptomic data identified photosynthetic antenna proteins as primary molecular targets, with both contaminants perturbing the transcriptional regulation of genes and impairing the structural plasticity of associated proteins. These molecular perturbations consequently disrupted the photosynthetic electron transport efficiency. Metabolomic evidence revealed subsequent carbohydrate metabolism imbalances, suggesting compromised carbon fixation capacity of C. demersum. Additionally, molecular docking simulations demonstrated superior binding affinities for both compounds with antenna proteins, particularly emphasizing the enhanced interactions mediated by 6PPD-Q's quinone structure. Comparative analysis indicated that 6PPD-Q's structural modifications may confer greater photosynthetic toxicity compared to the parent compound 6PPD. This multiomics investigation reveals the mechanistic basis of 6PPD and 6PPD-Q-driven photosynthetic toxicity and underscores their potential to destabilize aquatic ecosystems by disrupting primary productivity.

Topolow: a mapping algorithm for antigenic cross-reactivity and binding affinity assays.

Bioinformatics (Oxford, England), 41(7):.

MOTIVATION: Understanding antigenic evolution through cross-reactivity assays is crucial for tracking rapidly evolving pathogens requiring regular vaccine updates. However, existing cartography methods, commonly based on multidimensional scaling (MDS), face significant challenges with sparse and complex data, producing incomplete and inconsistent maps. There is an urgent need for robust computational methods that can accurately map antigenic relationships from incomplete experimental data while maintaining biological relevance, especially given that more than 95% of possible measurements could be missing in large-scale studies.

RESULTS: We present Topolow, an algorithm that transforms cross-reactivity and binding affinity measurements into accurate positions in a phenotype space. Using a physics-inspired model, Topolow achieved comparable prediction accuracy to MDS for H3N2 influenza and 56% and 41% improved accuracy for dengue and HIV, while maintaining complete positioning of all antigens. The method effectively reduces experimental noise and bias, determines optimal dimensionality through likelihood-based estimation, avoiding distortions due to insufficient dimensions, and demonstrates orders of magnitude better stability across multiple runs. We also introduce antigenic velocity vectors, which measure the rate of antigenic advancement of each isolate per unit of time against its temporal and evolutionary related background, revealing the underlying antigenic relationships and cluster transitions.

Topolow is implemented in R and freely available at https://doi.org/10.5281/zenodo.15620983 and https://github.com/omid-arhami/topolow.

Extensive data mining uncovers novel diversity among members of the rare biosphere within the Thermoplasmatota.

Microbiome, 13(1):155.

BACKGROUND: Rare species, especially of the marine sedimentary biosphere, have long been overlooked owing to the complexity of sediment microbial communities, their sporadic temporal and patchy spatial abundance, and challenges in cultivating environmental microorganisms. In this study, we combined enrichments, targeted metagenomic sequencing, and extensive data mining to uncover uncultivated members of the archaeal rare biosphere in marine sediments.

RESULTS: In protein-amended enrichments, we detected the ecologically and metabolically uncharacterized class Candidatus Penumbrarchaeia within the phylum Thermoplasmatota. By screening more than 8000 metagenomic runs and 11,479 published genome assemblies, we expanded the phylogeny of Ca. Penumbrarchaeia by 3 novel orders. All six identified families of this class show low abundance in environmental samples characteristic of rare biosphere members. Members of the class Ca. Penumbrarchaeia were predicted to be involved in organic matter degradation in anoxic, carbon-rich habitats. All Ca. Penumbrarchaeia families contain high numbers of taxon-specific orthologous genes, highlighting their environmental adaptations and habitat specificity. Besides, members of this group exhibit the highest proportion of unknown genes within the entire phylum Thermoplasmatota, suggesting a high degree of functional novelty in this class.

CONCLUSIONS: In this study, we emphasize the necessity of targeted, data-integrative approaches to deepen our understanding of the rare biosphere and uncover the functions and metabolic potential hidden within these understudied taxa. Video Abstract.

Transcriptomic profiling to unravel the underlying causes of early gonadal development of hilsa (Tenualosa ilisha) in Bangladesh.

Scientific reports, 15(1):22543.

Hilsa (Tenualosa ilisha) is crucial to Bangladesh's economy and ecology, but recent trends show early maturation in small-sized hilsa, with unclear causes. This study aimed to identify differentially expressed genes (DEGs) between the ovaries of large and small hilsa using RNA-sequencing. Samples from both sizes were collected from the Meghna River in Chandpur District, and four ovary libraries were sequenced via the Illumina platform. A total of 908 DEGs were detected, of which 453 were up-regulated and 455 were down-regulated. Transcriptome analysis revealed significant differences in Gene Ontology terms such as extracellular region (GO:0005576), innate immune response (GO:0045087), and protein ubiquitination (GO:0016567), peptide antigen binding (GO:0042605), KEGG pathways including MAPK signaling pathway (ko04010), endocytosis (ko04144), and spliceosome (ko03040), as well as COG terms like signal transduction, between the ovary of large and small hilsa shad. These findings suggest that differentially expressed genes may play a role in regulating the ovarian development of T. ilisha. However, the entire process, from sampling to final annotation, is described here, along with the workflow. This study will offer a valuable resource for current and upcoming Hilsa transcriptome-based expression profiling studies.

Spatiotemporal evolution and driving forces of landscape ecological risk in the lower reaches of the Yellow River from 2000 to 2020.

Scientific reports, 15(1):21375.

Rapid urban development and human activities have led to drastic changes in land use, resulting to heightened ecological pressures and risks to ecosystems, especially in cities along the lower reaches of the Yellow River (CLRYR), China. However, the landscape pattern and associated ecological risks in the CLRYR in the past twenty years remain unclear. In this study, we employed the land use data to identify the primary landscape types and their transformations, providing an in-depth analysis of the prevailing landscape pattern and the landscape ecological risk (LER) in the CLRYR. Additionally, we explored the spatial distribution of LER and investigated the underlying driving forces behind these changes. The results reveal that: (1) Cropland is the main landscape type in the CLRYR region; however, the area of cropland decreases with the transition to impervious. (2) Due to human activities, landscape fragmentation and diversity have gradually increased in CLRYR, while aggregation has gradually decreased, until there was some improvement between 2015 and 2020. (3) The LER in the CLRYR region exhibits instability, with values of 0.1761, 0.1751, 0.1760, 0.1773, and 0.1751 displaying a fluctuating downward trend. Directional distribution analysis indicates a movement of the LER center of gravity towards the mouth of the Yellow River, accompanied by an increasing dispersion pattern. Analysis of driving forces suggests that natural factors hold greater explanatory power compared to social factors. Moreover, interaction detection results reveal that the combined effect of any two factors surpasses that of a single factor. The findings offer a theoretical foundation for enhancing planning policies aimed at striking a balance between environmental preservation and social advancement within the CLRYR region.

An integrated GIS-pXRF approach assesses ecological and human health risks from heavy metals in county level soils.

Scientific reports, 15(1):22834.

Counties in China are the primary components of small and mid-sized city (SMC), and at the core of China's future urbanization and industrialization development. Land is an essential nature resource providing the basis for urban-rural development, which is directly influenced by anthropogenic processes and in turn has impacts on human health. Clarifying the distribution characteristics and causes of heavy metals (HMs) pollution in soils is key to ensuring human health, as well as promoting land sustainability at county-level. In order to efficiently identify high risk regions of HMs pollution, this study proposed a geographic information system (GIS)-portable X-ray fluorescence (pXRF)-based approach to measure local soil background of HMs and to screen high risk regions in Shangzhou, China. ICP-MS and pXRF results showed a good agreement of Cr, Ni, Cu, Zn, Pb and As with R[2] ranging from 0.757 to 0.966. Soil background of Ni, Cu, Zn, As and Pb had increased by 33.34-129.74% compared to 1990 levels. HMs concentrations in soils of urban-rural fringe were generally larger than those of urban and rural area. Particularly, soil background of Zn and Pb in urban-rural fringe exceeded 28.90% and 19.93% of urban area, 46.33% and 41.91% of rural area, respectively. In high soil background regions, 25% of sampling points were considered as moderate risk or above, with ecological risk index (RI) greater than 150. As, Cr and Ni were identified as major contributors to human health risk, and children were more vulnerable than adults with considerably total non-carcinogenic risk (THI = 1.46) and carcinogenic health risk (TCR = 1.52 × 10[- 4]). Anthropogenic process including industrial manufacturing, agricultural practice, urban expansion and land conversion brought about the HMs accumulation in soils. This study indicated industrial zone in urban-rural fringe should be priority-controlled, and provided scientific basis for urban-rural environmental management and human health risk protection.

Spatially Varying Selection Amplifies Intrapopulation Differentiation Among Phenotypic Traits in the Rocky-Shore Mussel, Mytilus californianus.

Ecology and evolution, 15(7):e71641.

Strong ecological gradients along heterogeneous environments play an important role in shaping population differentiation across species ranges. Thus, the selective pressure of environmental variation on phenotypic variation strongly affects an organism's ability to persist across diverse or new environments. We investigated the spatial variability of biological responses in the intertidal bivalve Mytilus californianus to highlight the costs and trade-offs of local adaptation and phenotypic plasticity across various functional traits in a dynamic environment, the marine intertidal. To test this, we performed a reciprocal transplant experiment with M. californianus individuals originating from the upper and lower intertidal measuring relevant phenotypic traits, followed by whole genome sequencing (WGS). We determined that morphological traits in individuals demonstrated phenotypic plasticity when moved to new environments, whereas physiological traits such as metabolism exhibited constraints in plasticity. Additionally, mussels from high intertidal zones, which experience greater heat and aerial exposure stress, maintained lower metabolic rates and showed increased frequencies of non-synonymous mutations in functionally relevant heat shock proteins when compared to low intertidal mussels. These results suggest that morphological and physiological traits responded differently to spatially varying selection within the marine intertidal.

Identification and characterization of novel CRESS-DNA viruses in the human respiratory tract.

Virology journal, 22(1):211.

CRESS-DNA viruses are small, circular, single-stranded DNA viruses that have been identified in diverse environments and hosts, including vertebrates, invertebrates, and environmental samples. However, their diversity and role in the human respiratory tract remain poorly understood. In this study, we employed viral metagenomics to analyze 140 nasopharyngeal swab samples from asymptomatic individuals. High-throughput sequencing and bioinformatics analyses were used to identify and characterize novel CRESS-DNA viruses. Phylogenetic relationships were inferred based on Rep protein sequences using maximum likelihood analysis. We identified and characterized eight novel CRESS-DNA viruses, which were classified into the families Endolinaviridae and Naryaviridae, with one potentially representing a novel viral family. These viruses exhibited typical circular genomic structures encoding Rep and Cap proteins, with conserved motifs associated with rolling circle replication. Phylogenetic analysis showed that some viruses were closely related to sequences from vertebrate hosts or environmental samples, suggesting a diverse ecological distribution. Our findings expand the known diversity of CRESS-DNA viruses in the human respiratory tract and highlight their potential ecological and evolutionary significance. Further studies are needed to explore their host specificity, replication mechanisms, and potential roles in human health and disease.

Root and foliar uptake, bidirectional translocation, subcellular distribution, and metabolism of tire wear particle-derived p-phenylenediamines and their quinones in Chinese cabbage and bok choy.

Environmental pollution (Barking, Essex : 1987), 382:126737 pii:S0269-7491(25)01110-8 [Epub ahead of print].

Tire wear particles (TWPs) and TWP-derived compounds have caused global concern for their toxicity, but their impacts on vegetables, particularly through foliar absorption, remain largely unknown. We investigated the absorption, translocation, accumulation, and metabolism of TWP-derived p-phenylenediamines (PPDs) and PPD-quinones (PPDQs) in hydroponic and soil-cultured leafy vegetables by exposing them to TWPs through roots and leaves. PPDs and PPDQs can be absorbed by vegetables through both roots and leaves, with subsequent bidirectional translocation within vegetables. TWPs with smaller particle sizes and higher aging degrees can release more PPDs and PPDQs, resulting in increased absorptions by the vegetables. Leaves with higher wax secretion, lipid content, and trichome abundance exhibit greater uptake capabilities. PPDs and PPDQs absorbed by leaves can be released back into the environment through roots. The subcellular distribution and translocation of PPDs and PPDQs in vegetables are mainly controlled by their octanol-water partition coefficients with highly hydrophobic congeners primarily accumulating in cell walls and organelles. We screened the 6PPD and 6PPDQ metabolites in leafy vegetables and found that their metabolic processes are influenced by their exposure medium and tissue specificity. The results highlight the risks posed by vegetables absorbing, accumulating, and metabolizing airborne TWP-derived chemicals through their leaves.

Evaluating the impact of land use and land cover change on soil moisture variability using GIS and remote sensing technology in southwestern Ethiopia.

Environmental monitoring and assessment, 197(7):824.

Soil moisture dynamics are critical for agriculture, water resources, and climate resilience in Ethiopia, influencing crop yields, water availability, and ecosystem health. Assessing soil moisture variability in relation to land use and cover (LULC) changes is essential for effective ecosystem conservation and climate change adaptation, ensuring sustainable development and resilience to environmental challenges. This study examines the impact of LULC changes on soil moisture variability in Southwestern Ethiopia over 30 years (1994-2024). Utilizing Landsat Thematic Mapper (1994), Enhanced Thematic Mapper Plus (2004), and Operational Land Imager/Thermal Infrared Sensor (2024) data, LULC changes were analyzed using supervised classification approach with the Maximum Likelihood Algorithm. The classification process was conducted using ERDAS Imagine 2015 software. In addition, vegetation health and soil moisture dynamics were assessed through the Normalized Difference Vegetation Index (NDVI) and the Normalized Difference Moisture Index (NDMI). Results reveal a significant increase in cultivated land from 3595.2 km[2] (42.0%) to 6183.3 km[2] (72.2%), with a corresponding decrease in forest cover from 3119.2 km[2] (36.4%) to 2030.4 km[2] (23.7%).This significant shift indicates intensive agricultural expansion at the expense of forest cover, highlighting increased land conversion pressures. NDVI values dropped from 0.71 in 1994 to 0.52 in 2024, this decline in NDVI values signifies a substantial reduction in vegetation cover and density over the 30-year period. The NDMI results indicated a decrease in peak moisture levels and average soil moisture, emphasizing a growing trend of intensified dryness. This soil moisture decline is attributed to factors such as reduced precipitation, increased evaporation, and changes in LULC. The conversion of forest land to cultivation led to a significant decrease in NDMI values, reflecting a reduction in soil moisture due to the loss of forest cover and increased evapotranspiration from agricultural activities. A strong correlation (R[2] = 0.98) between NDVI and NDMI highlights that higher vegetation cover is associated with higher soil moisture. Therefore, the study highlights the profound impact of land use and land cover changes on soil moisture, underscoring the urgent need for sustainable land management practices. These practices are critical to combat environmental degradation, improve soil moisture retention, and bolster ecosystem resilience, ensuring a sustainable and climate-resilient future.

Daily mobility, activity and environmental determinants of stress in ecological momentary assessment (EMA) and GPS studies: a scoping review protocol.

BMJ open, 15(6):e091509.

INTRODUCTION: Stress is omnipresent in our everyday lives and a key risk factor for our physical and mental health. Yet little is known about the impact of geographic life environments, linked to our daily activities and mobility patterns, on our momentary and daily stress levels.We propose this review to gather evidence on the spatio-temporal determinants of momentary or daily stress in studies using ecological momentary assessment (EMA) or experience sampling methods (ESM) in addition to global positioning systems (GPS) tracking. We will focus on the spatio-temporal definition and modelling of environmental exposures accounting for participant daily activities and mobility patterns and their association with stress.

METHODS AND ANALYSIS: This scoping review will follow the Preferred Reporting Items for Systematic Reviews and Meta-Analyses framework for scoping reviews (2018). We will search the PubMed/Medline, Web of Science, PsycInfo and Scopus databases. We will include papers using EMA or ESM and GPS measuring chronic, daily or momentary stress as an outcome; these methods are also referred to as geographically-explicit ecological momentary assessment.Articles published from January 2000-June 2025 will be screened. Two independent reviewers will screen titles and abstracts to agree on the inclusion of articles. No geographical or population limitation will be imposed.

ETHICS AND DISSEMINATION: This study is a scoping review based on previously published and publicly available literature. It does not involve the collection of primary data, human participants, or the processing of personal or sensitive information. Therefore, ethical approval is not required in accordance with institutional and international research ethics guidelines. The results will be submitted in peer-reviewed journals and presented at international conferences.

Enzymatic depolymerization of polyethylene using a small laccase and its potential for bio-upcycling.

Journal of hazardous materials, 495:139021 pii:S0304-3894(25)01937-5 [Epub ahead of print].

Polyethylene (PE) plastics present significant environmental challenges due to their recalcitrant nature and widespread usage. This study explores the biological degradation of PE using a novel enzyme, small laccase from Amycolatopsis sp. ATCC 39116 (ASLAC). Among four selected laccases, ASLAC demonstrated the highest biomass production using PE as a carbon source when expressed by Yarrowia lipolytica. Surface analysis of PE films treated with purified ASLAC, using scanning electron microscopy (SEM) and atomic force microscopy (AFM), revealed substantial degradation of the material. The degradation products were successfully utilized by Y. lipolytica, underscoring its potential for converting PE into bioenergy. Structural analysis and molecular docking simulations revealed that the substrate binding site of ASLAC, characterized by a hydrophobic planner configuration, is highly optimized for binding and cleaving PE polymers. This unique structure distinguishes it from other laccases with narrower or obstructed binding sites. Phylogenetic analysis of 311 small laccase sequences classified ASLAC into the Type-Ia subgroup, which exhibited superior potential for PE degradation. This study establishes ASLAC as a promising biocatalyst for sustainable PE management, providing a foundation for future applications in bioremediation and polymer upcycling.

PlantLncBoost: key features for plant lncRNA identification and significant improvement in accuracy and generalization.

The New phytologist, 247(3):1538-1549.

Long noncoding RNAs (lncRNAs) are critical regulators of numerous biological processes in plants. Nevertheless, their identification is challenging due to the low sequence conservation across various species. Existing computational methods for lncRNA identification often face difficulties in generalizing across diverse plant species, highlighting the need for more robust and versatile identification models. Here, we present PlantLncBoost, a novel computational tool designed to improve the generalization in plant lncRNA identification. By integrating advanced gradient boosting algorithms with comprehensive feature selection, our approach achieves both high accuracy and generalizability. We conducted an extensive analysis of 1662 features and identified three key features - ORF coverage, complex Fourier average, and atomic Fourier amplitude - that effectively distinguish lncRNAs from mRNAs. We assessed the performance of PlantLncBoost using comprehensive datasets from 20 plant species. The model exhibited exceptional performance, with an accuracy of 96.63%, a sensitivity of 98.42%, and a specificity of 94.93%, significantly outperforming existing tools. Further analysis revealed that the features we selected effectively capture the differences between lncRNAs and mRNAs across a variety of plant species. PlantLncBoost represents a significant advancement in plant lncRNA identification. It is freely accessible on GitHub (https://github.com/xuechantian/PlantLncBoost) and has been integrated into a comprehensive analysis pipeline, Plant-LncRNA-pipeline v.2 (https://github.com/xuechantian/Plant-LncRNA-pipeline-v2).

Improving Whole Biodiversity Monitoring and Discovery With Environmental DNA Metagenomics.

Molecular ecology resources, 25(6):e14105.

Environmental DNA (eDNA) metagenomics sequences all DNA molecules present in environmental samples and has the potential of identifying virtually any organism from which they are derived. However, due to unacceptable levels of false positives and negatives, this approach is underexplored as a tool for biodiversity monitoring across the tree of life, particularly for non-microscopic eukaryotes. We present SeqIDist, a framework that combines multilocus BLAST matches against several reference databases followed by an analysis of sequence identity distribution patterns to disentangle false positives while revealing new biodiversity and increasing the accuracy of metagenomic approaches. We tested SeqIDist on an eDNA metagenomic dataset from a riverine site and compared the results to those obtained with an eDNA metabarcoding approach for benchmarking purposes. We start by characterising the biological community (~2000 taxa) across the tree of life at low taxonomic levels and show that eDNA metagenomics has a higher sensitivity than eDNA metabarcoding in discovering new diversity. We show that limited representation of whole genome sequences in reference databases can lead to false positives. For non-microscopic eukaryotes, eDNA metagenomic data often consist of a few sparse, anonymous sequences scattered across the genome, making metagenome assembly methods unfeasible. Finally, we infer eDNA source and residency time using read length distributions as a measure of decay status. The higher accuracy of SeqIDist opens the discussion of the potential of eDNA metagenomics for archived samples and its implementation in long-term biodiversity monitoring at a planetary scale.

Correcting for Bias in Estimates of θ w and Tajima's D From Missing Data in Next-Generation Sequencing.

Molecular ecology resources, 25(6):e14104.

Population genetic analyses use information from the site frequency spectrum to infer evolutionary processes. Two summary statistics, Watterson's estimator (θ w) of genetic diversity, and Tajima's D , used for detecting non-neutral evolution, are among the most frequently computed statistics utilising this information. However, missing information in genomic data, particularly as encoded in the Variant Call Format (VCF), can bias these estimates, leading to incorrect evolutionary inferences. We assessed the impact of missing data on the estimation of these statistics using various population genetic software packages (VCFtools, PopGenome, pegas and scikit-allel). By simulating neutral genomic data with varying levels of missing genotypes and sites, we found consistent underestimation of θ w across programs. We found a consequent bias in estimates of Tajima's D , though the direction varied by software. We developed and implemented correction methods as functions in an update of the popular pixy software, significantly reducing these biases. Our findings highlight the need for accurate data handling in population genomics to avoid misinterpretations of evolutionary phenomena.

ParAquaSeq, a Database of Ecologically Annotated rRNA Sequences Covering Zoosporic Parasites Infecting Aquatic Primary Producers in Natural and Industrial Systems.

Molecular ecology resources, 25(6):e14099.

Amplicon sequencing tools such as metabarcoding are commonly used for thorough characterisation of microbial diversity in natural samples. They mostly rely on the amplification of conserved universal markers, mainly ribosomal genes, allowing the taxonomic assignment of barcodes. However, linking taxonomic classification with functional traits is not straightforward and requires knowledge of each taxonomic group to confidently assign taxa to a given functional trait. Zoosporic parasites are highly diverse and yet understudied, with many undescribed species and host associations. However, they can have important impacts on host populations in natural ecosystems (e.g., controlling harmful algal blooms), as well as on industrial-scale algae production, e.g. aquaculture, causing their collapse or economic losses. Here, we present ParAquaSeq, a curated database of available molecular ribosomal sequences belonging to zoosporic parasites infecting aquatic vascular plants, macroalgae and photosynthetic microorganisms, i.e. microalgae and cyanobacteria. These sequences are aligned with ancillary data and other information currently available, including details on their hosts, occurrence, culture availability and associated bibliography. The database includes 1131 curated sequences from marine, freshwater and industrial or artificial environments, and belonging to 13 different taxonomic groups, including Chytridiomycota, Oomycota, Phytomyxea, and Syndiniophyceae. The curated database will allow a comprehensive analysis of zoosporic parasites in molecular datasets to answer questions related to their occurrence and distribution in natural communities. Especially through meta-analysis, the database serves as a valuable tool for developing effective mitigation and sustainable management strategies in the algae biomass industry, but it will also help to identify knowledge gaps for future research.

Short Read Lengths Recover Ecological Patterns in 16S rRNA Gene Amplicon Data.

Molecular ecology resources, 25(6):e14102.

16S rRNA gene metabarcoding, the study of amplicon sequences of the 16S rRNA gene from mixed environmental samples, is an increasingly popular and accessible method for assessing bacterial communities across a wide range of environments. As metabarcoding sequence data archives continue to grow, data reuse will likely become an important source of novel insights into the ecology of microbes. While recent work has demonstrated the benefits of longer read lengths for the study of microbial communities from 16S rRNA gene segments, no studies have explored the use of shorter (< 200 bp) read lengths in the context of data reuse. Nevertheless, this information is essential to improve the reuse and comparability of metabarcoding data across existing datasets. This study reanalyzed nine 16S rRNA datasets targeting aquatic, animal-associated and soil microbiomes, and evaluated how processing the sequence data across a range of read lengths affected the resulting taxonomic assignments, biodiversity metrics and differential (i.e., before-after treatment) analyses. Short read lengths successfully recovered ecological patterns and allowed for the use of more sequences. Limited increases in resolution were observed beyond 150 bp reads across environments. Furthermore, abundance-weighted diversity metrics (e.g., Inverse Simpson index, Morisita-Horn dissimilarities or weighted Unifrac distances) were more robust to variation in read lengths. Read lengths alone contributed to consistent increases in the total number of ASVs detected, highlighting the need to consider metabarcoding-derived diversity estimates within the context of the bioinformatics parameters selected. This study provides evidence-based guidelines for the processing of short reads.

Popfinder: A Highly Effective Artificial Neural Network Package for Genetic Population Assignment.

Molecular ecology resources, 25(6):e14096.

The ability to assign biological samples to source populations with high accuracy and precision based on genetic variation is important for numerous applications from ecological studies through wildlife conservation to epidemiology. However, population assignment when genetic differentiation is low is challenging, and methods to address this problem are lacking. The application of artificial neural networks to population assignment using genomic data is highly promising. Here we present popfinder: a new, easy-to-use Python-based artificial neural network pipeline for genetic population assignment. We tested popfinder both with simulated genetic data from populations connected by varying levels of gene flow and with reduced-representation sequence data for three species of seabirds with weak to no population genetic structure. Popfinder was able to assign individuals to their source populations with high accuracy, precision and recall in most cases, including both simulated and empirical data sets, except in the empirical data set with the weakest population structure, where the comparator programs also performed poorly. Compared to other available software, popfinder was slower on the simulated data sets due to hyperparameter tuning and the fact that it does not reduce the dimensionality of the data set; however, all programs ran in seconds on empirical data sets. Additionally, popfinder provides a perturbation ranking method to help develop optimised SNP panels for genetic population assignment and is designed to be user-friendly. Finally, we caution users of all assignment programs to watch both for leakage of data during model training, which can lead to overfitting and inflation of performance metrics, and for unequal detection probabilities.

Sapflow Database Reveals Density-Dependent Competition Among Woody Plants at Global Scale.

Ecology letters, 28(6):e70167.

Though limiting resources differ among systems, water is limiting in most arid and many mesic systems, potentially allowing for direct measurement of competition by measurement of water uptake. Sapflow measurements provide a direct measure of water movement through plant stems, but, to our knowledge, sapflow has never been used to study density dependence and competition at large (regional or global) scales. Here, we examine a global database of sapflow measurements, the SapFluxNet database, for signs of density-dependent competition for water. We find that plant-level water uptake decreases with increasing competition from neighbours (specifically, neighbourhood basal area). Further analysis demonstrates that global-scale variability in annual sapflow can be largely explained (R[2] = 0.522) by the combination of average vapour pressure and neighbourhood summed basal area. This analysis provides a rare quantification of plant competition for a limiting resource inferred directly via measurements of resource acquisition (i.e., sapflow).

Integrating Traditional Nutritional Wisdom into Digital Nutrition Platforms: Toward Culturally Adaptive and Inclusive Health Technologies.

Nutrients, 17(12):.

Background/Objectives: Traditional nutritional knowledge, shaped by centuries of cultural and ecological adaptation, offers holistic and sustainable dietary frameworks that remain highly relevant to modern health challenges. However, current digital nutrition platforms often fail to reflect this diversity, relying instead on standardized models with limited cultural sensitivity. This paper aims to explore how traditional nutritional wisdom can be integrated into digital health platforms to promote more inclusive and effective approaches to personalized nutrition. Methods: This perspective paper employs a cultural adaptation framework to analyze the integration of traditional food knowledge into digital contexts. Drawing from interdisciplinary research across nutrition science, anthropology, digital health and implementation science, we utilize the Knowledge-to-Action (KTA) Framework and the PEN-3 Cultural Model to structure our analysis. A systematic scoping review of literature published between 2010 and 2025 was conducted to identify integration challenges and opportunities. Additionally, we analyzed case studies of three traditional dietary systems (Argentina, Italy and Japan) and evaluated five leading digital nutrition platforms for their degree of cultural inclusivity, using qualitative comparative methods. Results: The analysis highlights significant challenges in adapting traditional knowledge to digital formats, including standardization barriers, contextual loss and technological limitations. However, successful integration initiatives demonstrate that through participatory design, flexible data architectures and culturally-informed algorithms, traditional food systems can be meaningfully represented. Our proposed four-phase integration framework-documentation, digital adaptation, implementation and evaluation-provides a structured approach for developers and researchers. Conclusions: Bridging traditional nutrition with digital platforms represents a vital opportunity to enhance personalization and preserve food heritage while improving health outcomes for diverse populations. This integration requires interdisciplinary collaboration, user-centered design processes and ethical approaches that respect cultural ownership and context.

A comparative study of fully automatic and semi-automatic methods for oil spill detection using Sentinel-1 data.

Environmental monitoring and assessment, 197(7):808.

The oil spill detection and assessment study conducted in the Banten Province of Indonesia involves the application of Sentinel-1 satellite data and machine learning tools in the year 2024. Synthetic Aperture Radar (SAR) data were used with VV polarization to observe the surface characteristics, using an oil spill threshold of - 25 dB to differentiate clean water from the oil spill based on low backscatter intensity. After desiring image processing and binary masking applications on the data that improve visibility of the oil spill-affected zones, vectorization was conducted for integration into geographic information systems (GIS). A temporal analysis indicated high variability across the spill sizes with an extreme peak on May 16 (79.686 km[2]) and July 3 (41.593 km[2]), which are likely dictated by the weather and oceanographic conditions plus the ship traffic of that time. Wind pattern analysis via ERA5 reanalysis data presented more insight into spill dispersion dynamics. Three machine learning classifiers were applied toward oil spill detection, namely Artificial Neural Networks (ANN), Random Forest (RF), and Extreme Gradient Boosting (XGBoost). Performance metrics indicate the ANN outperformed in discriminative ability (AUC = 0.92), while RF was highly accurate (99.01%) and precise (99.02%). This clearly demonstrates the viability of using an integrated approach of remote sensing, advanced image processing, and supervised learning for environmental monitoring and provides important information for minimizing ecological impacts and optimizing disaster response plans for maritime areas. Such an integrated scheme calls for advanced technology to combat ecological threats in maritime areas and provides crucial evidence toward ongoing interventions to protect and manage marine ecosystems and the associated local communities.

Optimal sampling frequency and site selection for wastewater and environmental surveillance of infectious pathogens: A value of information assessment.

PLoS computational biology, 21(6):e1013190.

Wastewater and environmental surveillance (WES) is a promising method of detecting infectious diseases in human and animal populations and offers significant advantages over traditional surveillance methods in the early detection of outbreaks. However, WES involves financial and human resources, and public policy decisions must determine whether the benefits of WES outweigh the costs, particularly in low-resource areas. The selection of surveillance sites, sampling frequency, and test sensitivity and specificity are crucial determinants of WES effectiveness and cost-efficiency. We created an analytical model and numerical simulations of disease arrival, spread, and WES strategies to determine the optimal sampling frequency for two interacting patches, each represented by a different sampling site. We show that it is optimal to test in one patch more frequently than it is to test in both patches less frequently if the patches are sufficiently interactive, surveillance is of sufficient sensitivity and specificity, and setup costs are substantial. In our value of information (VOI) assessment, the net value of surveillance information for both patches is non-monotonic with respect to the degree of patch interaction. Increased mixing between the patches allows for quicker surveillance detection but is worse for overall infection burden. Overall, optimizing the value of surveillance information for all patches being surveilled requires coordination and deliberate selection of surveillance sites and sampling frequencies. This paper provides a VOI assessment of WES to determine the optimal number of sites and sampling frequency at a high level of abstraction, leaving opportunity to adapt the model to specific pathogens and populations as needed. Our findings can inform the cost-efficient implementation of WES for infectious diseases, particularly in resource-constrained settings.

High-resolution multiomics links nutrients and mixotrophy to toxicity in a harmful bloom of the haptophyte Chrysochromulina leadbeateri.

Science advances, 11(26):eadv3390.

Harmful algal blooms (HABs) of the toxigenic haptophyte Chrysochromulina are known to cause fish mortalities and collateral ecosystem damage. The ichthyotoxic mechanisms are poorly understood but likely dependent on toxigenesis by polyketide synthases (PKSs). We hypothesize that induction of PKS activity facilitates mixotrophic behavior during nutrient-depleted bloom conditions. To identify potential in situ stimuli for growth, toxigenicity, and bloom persistence, we compared environmental factors and biological processes identified by metaomics to Chrysochromulina leadbeateri HABs between two fjords in northern Norway. We identified the polyketide ichthyotoxin leadbeaterin-1 from the C. leadbeateri bloom and found potentially associated candidate PKS genes of which most were higher expressed at bloom stations. A relative depletion of inorganic nitrogen and phosphate during the bloom was correlated with higher expression of genes involved in endocytosis, autophagy, and lysosomal activity. Mixotrophy is evidently a compensatory nutritional strategy coupled to induction of toxigenesis and other metabolomic processes as biotic factors linked to Chrysochromulina bloom dynamics.

Eco-Evolutionary Guided Pathomic Analysis Detects Biomarkers to Predict Ductal Carcinoma In Situ Upstaging.

Cancer research, 85(13):2537-2547.

UNLABELLED: Cancers evolve in a dynamic ecosystem. Thus, characterizing the ecological dynamics of cancer is crucial to understanding cancer evolution, which can lead to the discovery of biomarkers to predict disease progression. Ductal carcinoma in situ (DCIS) is an early-stage breast cancer characterized by abnormal epithelial cell growth confined within the milk ducts, and biomarkers are needed to predict which cases will progress to aggressive disease. In this study, we showed that ecological analysis of hypoxia and acidosis biomarkers can significantly improve prediction of DCIS upstaging. Quantitative analyses were performed on immunohistologic images from a retrospective cohort of DCIS specimens collected from biopsy samples. First, an eco-evolutionary designed approach was developed to define habitats in the tumor intraductal microenvironment based on oxygen diffusion distance. Then, cancer cells with metabolic phenotypes attributed to their habitats were identified, including a hypoxia-responding CA9+ phenotype and an acid-adapted LAMP2b+ phenotype. Whereas these markers have traditionally shown limited, if any, predictive capabilities for DCIS progression when analyzed from an ecological perspective, their power to differentiate between non-upstaged and upstaged DCIS increased significantly. Additionally, the distribution of distinct niches with specific spatial patterns of these biomarkers predicted patient upstaging. The niches were characterized by pattern analysis of both cellular and spatial features. A random forest classifier that was trained and underwent a five-fold validation on the biopsy cohort achieved an AUC of 0.74 for predicting clinical outcome. These results affirm the importance of tumor ecological features in eco-evolutionary-designed approaches for biomarker discovery.

SIGNIFICANCE: Evolutionary dynamics of the various niches composing the tumor ecosystem can be harnessed for predicting cancer progression, demonstrating how eco-evolutionary-designed approaches can guide biomarkers discovery studies in the era of digital pathology. This article is part of a special series: Driving Cancer Discoveries with Computational Research, Data Science, and Machine Learning/AI.

Social jetlag decreases across the lifespan: A prospective big data analysis of objective sleep metrics.

Journal of sleep research, 34(4):e14433.

Changes in social zeitgebers across the lifespan affect the interaction between biological and social clocks, potentially contributing to social jetlag. Extant literature suggests a reduction in social jetlag given declining social obligations occurring after retirement, but is limited to self-reported methods and cross-sectional designs. Leveraging longitudinal and ecologically valid data from consumer sleep technology, we analysed objective sleep data from 2439 users of the polysomnography-validated SleepScore mobile application, encompassing 500,415 total nights recorded. We examined the relationship between age as a continuous variable, age as a proxy for retirement status, and social jetlag. Additional linear models were employed to assess the effect of self-reported chronotype, average reported daily caffeine, alcohol and stress on social jetlag. There was a significant negative association between overall age and social jetlag (β = -0.64, t = -9.90, p < 0.001, effect size = 0.040), such that every 1-year increase in age corresponded with a 0.64-min reduction in social jetlag. The inclusion of self-reported chronotype, stress, caffeine and alcohol increased the explanatory power of our models slightly, but the effect of age remained consistent (β = -0.642, t = -8.91, p < 0.001, effect size = 0.046). Retirement-aged individuals exhibited nearly 50% less reduction in social jetlag than pre-retirement (30.6 ± 48.2 min versus post-retirement: 15.8 ± 41.6 min, p < 0.0001). While social jetlag after retirement was most pronounced for strong evening chronotypes (β = -0.41, t = -2.876, p = 0.004, effect size = -0.4276), pairwise comparisons revealed no statistically significant differences in the slopes between chronotypes (p > 0.05). Thus, social jetlag decreases across the lifespan, and its reduction appears to be amplified post-retirement even after accounting for behavioural factors.

Nanomaterials (Basel, Switzerland), 15(12):.

The rational design of photoanode materials is pivotal for advancing photoelectrochemical (PEC) water splitting toward sustainable hydrogen production. This review highlights recent progress in the machine learning (ML)-assisted development of nanostructured metal oxide photoanodes, focusing on bridging materials discovery and device-level performance optimization. We first delineate the fundamental physicochemical criteria for efficient photoanodes, including suitable band alignment, visible-light absorption, charge carrier mobility, and electrochemical stability. Conventional strategies such as nanostructuring, elemental doping, and surface/interface engineering are critically evaluated. We then discuss the integration of ML techniques-ranging from high-throughput density functional theory (DFT)-based screening to experimental data-driven modeling-for accelerating the identification of promising oxides (e.g., BiVO4, Fe2O3, WO3) and optimizing key parameters such as dopant selection, morphology, and catalyst interfaces. Particular attention is given to surrogate modeling, Bayesian optimization, convolutional neural networks, and explainable AI approaches that enable closed-loop synthesis-experiment-ML frameworks. ML-assisted performance prediction and tandem device design are also addressed. Finally, current challenges in data standardization, model generalizability, and experimental validation are outlined, and future perspectives are proposed for integrating ML with automated platforms and physics-informed modeling to facilitate scalable PEC material development for clean energy applications.

Proportional Stroke Mortality in Espírito Santo, Brazil: A 20-Year Joinpoint Regression Study.

Epidemiologia (Basel, Switzerland), 6(2):.

Introduction: Stroke is one of the leading causes of death and disability worldwide. In Brazil, it remains the primary cause of mortality among adults. Although overall stroke mortality rates have declined, the absolute number of stroke incidents, deaths, and years of life loss continues to rise, particularly in developing and underdeveloped countries. Objective: The aim of this study was to analyze trends in stroke mortality across different age groups and both sexes in Espírito Santo, Brazil, from 2000 to 2021. Methods: This ecological time series study utilized secondary data from Espírito Santo, Brazil, from 2000 to 2021. Mortality data, categorized by sex and age group, were obtained from the Department of Informatics of the Unified Health System (DATASUS) database. Stroke-related mortality included deaths recorded under the International Classification of Diseases, 10th Revision (ICD-10) codes for subarachnoid hemorrhage (I60), intracerebral hemorrhage (I61), cerebral infarction (I63), and stroke not specified as hemorrhagic or ischemic (I64). Temporal trends in stroke mortality were assessed using joinpoint regression analysis. Results: From 2000 to 2021, there was a significant reduction in proportional mortality from stroke, with an overall decrease of -3.7% (p < 0.001). When analyzed by sex, the decline was -3.0% (p < 0.001) for males and -3.9% (p < 0.001) for females. The most significant decrease in proportional mortality was observed in the 50 to 59 age group, with an average annual percentage change of -4.9% (p < 0.001). The 30 to 39 age group exhibited the smallest decline, with an average annual percentage change of -2.4% (p < 0.001). No significant segments were observed in the 40 to 49, 60 to 69, and 70 to 79 age groups during the study period. Conclusions: This study identified a notable decline in stroke-related proportional mortality in the adult population of Espírito Santo between 2000 and 2021. While males had a higher absolute number of deaths, females exhibited a higher proportional mortality rate, underscoring the need for targeted preventive measures and effective acute stroke treatment, particularly among men.

Local variation in musculoskeletal pain consultation rates in primary care: findings from an ecologic study in Staffordshire.

Primary health care research & development, 26:e52.

Variation between general practices in the rate of consultations for musculoskeletal pain conditions may signal important differences in access to primary care, perceived usefulness, or available alternative sources of care; however, it might also just reflect differences in underlying 'need' between practices' registered populations. In a study of 30 general practices in Staffordshire, we calculated the proportion of adults consulting for a musculoskeletal pain condition, then examined this in relation to selected practice and population characteristics, including the estimated prevalence of self-reported musculoskeletal problems and chronic pain in each practices' registered population. Between September 2021 and July 2022, 18,388 adults were consulted for a musculoskeletal pain condition. After controlling for length of recruitment, time of year, and age-sex structure, the proportion consulting varied up to two-fold between practices but was not strongly associated with the prevalence of self-reported long-term musculoskeletal problems, chronic pain, and high-impact chronic pain.

Integrating multi-omics and biomarkers to reveal the stress mechanisms of high fluoride on earthworms.

Journal of hazardous materials, 494:138706.

Excessive fluorine accumulation poses a significant threat to soil ecology and even human health, yet its impact on soil fauna, especially earthworms, remains poorly understood. This study employed multi-omics and biomarkers to investigate high fluorine-induced biochemical changes that cause tissue damages in Eisenia fetida. The results demonstrated that earthworms exhibited obvious damage with fluorine addition exceeding 200 mg kg[-1], with stress levels escalating as fluorine contents increased. Further analysis of the underlying mechanisms revealed that fluorine could upregulate genes encoding mitochondrial respiratory chain complexes I-III and downregulate those for IV-V, leading to reactive oxygen species (ROS) accumulation despite antioxidant system activation. The resulting ROS interfered with deoxyribonucleoside triphosphate synthesis, prompting homologous recombination as the main DNA repair mechanism. Additionally, fluorine-induced ROS also attacked and disrupted protein and lipid related metabolisms ultimately causing oxidative damages. These cumulative oxidative damages from high fluorine contents subsequently triggered autophagy or apoptosis, resulting in tissue ulceration and epithelial exfoliation. Therefore, high fluorine could threaten earthworms by inducing ROS accumulation and subsequent biomolecule damages.

Deciphering the joint intracellular and extracellular regulatory strategies of toxigenic Microcystis to achieve intraspecific competitive advantage: An integrated multi-omics analysis with novel allelochemicals identified.

Water research, 283:123774.

Global increase in Microcystis-dominated cyanobacterial blooms (MCBs) severely threatens ecological and human health. Intraspecific interaction between microcystin (MC)-producing (MC[+]) Microcystis and co-existing MC-free (MC[-]) Microcystis influences the relative abundance of MC[+]Microcystis, ultimately determining the toxicity and hazard of MCBs. However, specific allelochemicals driving this interaction and underlying molecular mechanisms remain unclear. This study confirmed that intraspecific interaction promoted the competitive advantage of MC[+]Microcystis over MC[-]Microcystis and unveiled the joint intracellular and extracellular regulatory strategies of MC[+]Microcystis based on proteomics-metabolomics analyses and biochemical validation. Intracellularly, MC[+]Microcystis enhanced pentose phosphate pathway and lipid and fatty acid biosynthesis to maintain cellular functions and membrane stability, but inhibited glycolysis, tricarboxylic acid cycle, and protein biosynthesis to optimize energy utilization for growth and proliferation. Extracellularly, MC[+]Microcystis released allelochemicals, including cytidine diphosphate-diacylglycerol and N-acyl-homoserine lactones, to inhibit MC[-]Microcystis growth by 13.53% and 16.39%, respectively, thereby achieving its competitive advantage. In contrast, MC[-]Microcystis exhibited the suppressed photosynthesis and oxidative phosphorylation, imbalanced anti-inflammatory responses, nucleic acid degradation, and membrane damage, resulting in its competitive disadvantage in co-culture. These findings provide new insights into the competitive dynamics between MC[+] and MC[-]Microcystis, and their involved implications for aquatic ecosystem health.

Integrated multi-omics and DNA stable-isotope probing approaches to reveal soil-ryegrass response to ionic rare earth mineral ammonium-lead contamination.

Journal of hazardous materials, 494:138658.

The extensive use of ammonium (NH4[+]) sulfate in ionic rare earth mining has resulted in soil contamination with NH4[+] and lead (Pb), posing significant challenges for ecological restoration. Here, multi-omics and DNA stable-isotope probing (DNA-SIP) approaches were utilized to investigate soil nitrogen cycling and the molecular response of ryegrass (Lolium perenne L.) to NH4[+] (180-720 mg kg[-1])-Pb[2+] (207-828 mg kg[-1]) co-contamination. A synergistic interaction between NH4[+] and Pb[2+] was observed, significantly inhibited ryegrass growth, and induced oxidative stress and mitochondrial swelling. The EC50 toxicity thresholds were 383 mg kg[-1] for NH4[+] and 512 mg kg[-1] for Pb. The Integrated Biomarker Response (IBRv2) model elucidated the synergistic toxic effects. Transcriptomic and metabolomic analyses indicated that ryegrass roots enhanced carbon metabolism and antioxidant response pathways related to stress tolerance. Galactose metabolism and lysine degradation were identified as key pathways associated with stress response. Co-contamination with NH4[+] and Pb[2+] reduced ryegrass root [15]N-total nitrogen (TN) by 30 % while increasing soil [15]N-NH4[+] residue by 95 % and decreasing [15]N-microbial biomass nitrogen (MBN) by 59 %, compared to NH4[+] single contamination. DNA-SIP analysis revealed that ryegrass cultivation under NH4[+]- Pb[2+] co-contamination increased the abundance of plant growth-promoting rhizobacteria (Dyella), acid-tolerant nitrogen (Acidibacter), and sulfur-cycling taxa (Desulfosporosinus). The presence of raffinose and chlorogenic acid in ryegrass root metabolites was associated with shifts in the structure and composition of using NH4[+] active microbial taxa. These findings provide valuable insights into plant-soil-microbe interactions under multi-pollutant stress and offer practical strategies for phytoremediation and ecological restoration in areas affected by mining.

PFHxA and PFHxS promote breast cancer progression in 3D culture: MEX3C-associated immune infiltration revealed by bioinformatics and machine learning.

Journal of hazardous materials, 494:138458.

Per- and polyfluoroalkyl substances (PFAS) are persistent environmental contaminants with widespread use and bioaccumulative potential. Short-chain PFAS such as perfluorohexanoic acid (PFHxA) and perfluorohexane sulfonate (PFHxS) have been introduced as safer alternatives to long-chain PFAS, yet their toxicological impacts remain poorly defined. In this study, we employed a 3D Gelatin methacryloyl (GelMA) hydrogel model to mimic the tumor microenvironment and investigated the effects of PFHxA and PFHxS on triple-negative breast cancer (TNBC) progression. At environmentally relevant concentrations (0.1-10 μM), both compounds significantly enhanced proliferation, migration, and invasion of MDA-MB-231 cells. Transcriptomic and machine learning analyses identified MEX3C as a key gene upregulated by PFAS exposure. Gene set enrichment analysis (GSEA) revealed activation of the PI3K-AKT-mTOR signaling pathway, which was further supported by siRNA-mediated knockdown of MEX3C, leading to a marked reduction in the expression levels of phosphorylated PI3K, AKT, and mTOR proteins. Furthermore, immune cell co-culture experiments showed that MDA-MB-231 cells with high MEX3C expression promoted M2 macrophage polarization, suppressed M1 polarization, and enhanced macrophage chemotactic activity, the immunomodulatory effects were significantly attenuated upon MEX3C knockdown. These findings establish MEX3C as a central mediator of PFAS-induced tumor progression and immune remodeling. This study provides mechanistic insight into the carcinogenic potential of emerging short-chain PFAS and underscores the need for stricter regulation to safeguard public health.

Requirements and Considerations for Effective Implementation of Integrated One Health Antimicrobial Resistance Research.

Canadian journal of microbiology [Epub ahead of print].

The One Health (OH) approach recognizes the interconnectedness of the health of people, animals, plants/crops and ecosystems, and is central to addressing antimicrobial resistance (AMR). The 7th Environmental Dimension of Antimicrobial Resistance Conference (EDAR7), held in Montreal in May 2024, exemplified this approach by convening international experts and stakeholders to discuss AMR research and policy progress. EDAR7 workshop #8 focused on 1) barriers to establishing effective OH AMR research programs, 2) gaps in OH AMR research priorities, and 3) potential solutions/approaches or 'tools' to ensure programs develop in accordance with OH principles and generate insightful data that maximizes limited resources. Key workshop outcomes included identifying critical principles for OH AMR research programs and highlighting the pivotal role of sustainable data management strategies. Additionally, the importance of considering AMR policy and risk assessment needs when planning and designing research was emphasized. Discussions explored specific tools and approaches that support the standardized and harmonized collection and analysis of data, and associated challenges of integrating genomics data into current risk assessments and models. Synthesis of the workshop's discussions outlined critical considerations that interdisciplinary OH AMR research programs and networks should prioritize to enhance the impact of their outputs.

Integrative omics analysis of plant-microbe synergies in petroleum pollution remediation.

PeerJ, 13:e19396.

As the petrochemical industry continues to advance, the exacerbation of ecological imbalance and environmental degradation due to petroleum pollution is increasingly pronounced. The synergistic interaction between plants and microorganisms are pivotal in the degradation of petroleum hydrocarbons; however, the underlying degradation mechanisms are not yet fully understood. This study aims to contribute to understanding these mechanisms by employing a multi-omics approach, integrating transcriptomics, 16S rRNA gene sequencing, and metabolomics, to analyze key differential genes, dominant microbial strains, and root-secreted metabolites involved in petroleum hydrocarbon degradation in alfalfa. Our findings revealed that several stress-related genes are upregulated in alfalfa contaminated with petroleum hydrocarbon. Moreover, Pseudomonas, Rhodococcus, and Brevundimonas were identified as dominant species in the rhizosphere microbiome. Metabolomics analysis identified pantothenic acid, malic acid, and ascorbic acid as critical metabolites that enhance hydrocarbon degradation. Application of pantothenic acid in oil-contaminated soil increased the degradation rate by approximately 10% compared to other treatments. These results highlight the potential of alfalfa-based phytoremediation strategies and offer a novel perspective for improving the efficiency of soil decontamination. Further research is needed to validate the scalability of these strategies for practical applications.

Exploring Factors Related to Social Isolation Among Older Adults in the Predementia Stage Using Ecological Momentary Assessments and Actigraphy: Machine Learning Approach.

Journal of medical Internet research, 27:e69379 pii:v27i1e69379.

BACKGROUND: As the global population ages, the economic burden of dementia continues to rise. Social isolation-which includes limited social interaction and feelings of loneliness-negatively affects cognitive function and is a significant risk factor for dementia. Individuals with subjective cognitive decline and mild cognitive impairment represent predementia stages in which functional decline may still be reversible. Therefore, identifying factors related to social isolation in these at-risk groups is crucial, as early detection and intervention can help mitigate the risk of further cognitive decline.

OBJECTIVE: This study aims to develop and validate machine learning models to identify and explore factors related to social interaction frequency and loneliness levels among older adults in the predementia stage.

METHODS: The study included 99 community-dwelling older adults aged 65 years and above in the predementia stage. Social interaction frequency and loneliness levels were assessed 4 times daily using mobile ecological momentary assessment over a 2-week period. Actigraphy data were categorized into 4 domains: sleep quantity, sleep quality, physical movement, and sedentary behavior. Demographic and health-related survey data collected at baseline were also included in the analysis. Machine learning models, including logistic regression, random forest, Gradient Boosting Machine, and Extreme Gradient Boosting, were used to explore factors associated with low social interaction frequency and high levels of loneliness.

RESULTS: Of the 99 participants, 43 were classified into the low social interaction frequency group, and 37 were classified into the high loneliness level group. The random forest model was the most suitable for exploring factors associated with low social interaction frequency (accuracy 0.849; precision 0.837; specificity 0.857; and area under the receiver operating characteristic curve 0.935). The Gradient Boosting Machine model performed best for identifying factors related to high loneliness levels (accuracy 0.838; precision 0.871; specificity 0.784; and area under the receiver operating characteristic curve 0.887).

CONCLUSIONS: This study demonstrated the potential of machine learning-based exploratory models, using data collected from mobile ecological momentary assessment and wearable actigraphy, to detect vulnerable groups in terms of social interaction frequency and loneliness levels among older adults with subjective cognitive decline and mild cognitive impairment. Our findings highlight physical movement as a key factor associated with low social interaction frequency, and sleep quality as a key factor related to loneliness. These results suggest that social interaction frequency and loneliness may operate through distinct mechanisms. Ultimately, this approach may contribute to preventing cognitive and physical decline in older adults at high risk of dementia.

"No rest for me tonight": A social-ecological exploration of insomnia in rural Appalachian women.

Sleep health pii:S2352-7218(25)00085-3 [Epub ahead of print].

OBJECTIVES: Insomnia disproportionally affects women and is prevalent among rural Appalachian adults at higher rates than in the general US population. Given the strong, bi-directional relationship between sleep and health, a better understanding of insomnia in this health-disparate population is critical. The present study focused on the sex (females), gender (women), and age group (45+) at highest insomnia risk and explores the social determinants of sleep that contributed to insomnia.

METHODS: Semistructured telephone interviews were conducted to understand factors associated with insomnia among rural Appalachian women who self-reported insomnia symptoms ≥3 nights per week for ≥3months. Interviews were recorded with permission and transcribed. We used a multistage, inductive and deductive coding process aided by NVIVO 12.0 software.

RESULTS: Participants were 46 cisgender women in rural Appalachia who met the criteria for insomnia. The social-ecological model was our interpretative framework. Findings illuminate individual (e.g., rumination, menopause, pain, depression), social (e.g., family roles, grief, caregiving, financial concerns), and societal (e.g., gender norms, technology use) factors that likely contribute to insomnia among middle-aged rural Appalachian women.

CONCLUSIONS: Across levels of the social-ecological model, factors of female sex (e.g., menopause) and gendered behaviors, roles, and norms (e.g., caregiving close and extended kin) played a central role in the precipitation and perpetuation of insomnia in this population. Attending to the regional cultural norms of heightened self-sufficiency, domestic work, and inter-generational familial care may aid healthcare providers and policy makers aiming to address insomnia among rural Appalachian women as well as other rural populations.

Multi-omics approaches: transforming the landscape of natural product isolation.

Functional & integrative genomics, 25(1):132.

The field of natural product (NPs) discovery has significantly evolved with the advent of multi-omics approaches, encompassing genomics, transcriptomics, proteomics, and metabolomics. This review highlighting targeted isolation strategies and the comprehensive applications of omics in investigating natural products. Omics technologies, including genomics, transcriptomics, proteomics, and metabolomics, have emerged as powerful tools that revolutionize the traditional methods of natural product discovery. This review delves into the integration of multi-omics technology in the isolation and discovery of natural product. Omics applications in natural product investigation have revolutionized the field by enabling high-throughput screening, rapid identification of novel compounds, and understanding the complex interactions within biological systems. For instance, metabolomics gives insights into the metabolic profiles of organisms under different conditions, aiding in the discovery of unique NPs with potential therapeutic applications. Genomics has facilitated the mining of microbial genomes for biosynthetic gene clusters, leading to the discovery of new antibiotics and carcinopreventive agents. Transcriptomics and proteomics provide insights into gene expression and protein synthesis, revealing the dynamics of NPs biosynthesis under various conditions. Despite these limitations, the future prospects of multi-omics in natural product discovery are promising. Advances in omics technologies, coupled with machine learning and artificial intelligence, are expected to enhance data integration and predictive modeling, accelerating the discovery and development of innovative drugs. Furthermore, the continuous improvement in analytical techniques and the establishment of comprehensive databases will facilitate the identification and characterization of NPs, ultimately contributing to the development of new therapeutic agents. Collaborative efforts across disciplines and the integration of environmental and ecological data will further enhance our understanding of NP biosynthesis and lead to more effective and sustainable drug discovery strategies.

Fluctuations in Daily Happiness and Nervousness Based on Depressive and Anxious Symptoms in Adolescents or Young Adults Across 3 Latin American Cities: Experience Sampling Study.

JMIR formative research, 9:e65732.

BACKGROUND: Experience sampling methods (ESMs) have been used in clinical research to collect data on emotional and behavioral states in real-life contexts among different populations. Although the use of ESMs in mental health has increased, it has not been applied to larger samples of young people in disadvantaged urban settings.

OBJECTIVE: This study aimed to determine the extent to which mood status scores (happiness and nervousness) vary during a week, as a function of having or not having symptoms of depression or anxiety, in a sample of adolescents and young adults in the cities of Buenos Aires, Bogotá, and Lima. A secondary objective was to identify factors associated with mood scores, including sociodemographics, quality of life, and daily activities.

METHODS: This study was part of the Building Resilience and Resources to Reduce Mental Distress in Young People in Latin America research program, which focuses on mental health resources for young people. Participants (n=143) aged 15-24 years completed daily ESM assessments over a week using the mobile app, resulting in 5246 reports. Data were analyzed using descriptive analyses with 2-tailed t tests and chi-square tests, and multilevel linear regression was used to examine associations between depressive or anxiety symptoms, mood variability, and factors influencing mean mood. Finally, Spearman correlation assessed the relationship between happiness and nervousness.

RESULTS: The analysis revealed that depressive or anxiety symptoms were not significantly associated with increased variability in mood scores (happiness P=.40 and nervousness P=.84). However, males exhibited greater variability in happiness and nervousness scores (P<.001) than females. Additionally, young people showed higher variability in nervousness than adolescents (P=.02). Regarding average happiness scores, young adults reported higher average happiness than adolescents (β=.604; P=.003). Engaging in structured activities (eg, sports, music lessons, and dance classes) was associated with increased happiness (β=.266; P=.01). In contrast, instrumental activities (eg, cleaning, shopping, meal preparation, or taking medication; β=-.144; P=.02) and work-related tasks (β=-.205; P=.01) were linked to lower happiness and higher nervousness (β=.387; P<.001). Quality of life was positively correlated with happiness (β=.486; P<.001) and negatively correlated with nervousness (β=-.273; P=.005). Finally, as for average scores, a strong negative correlation was found between happiness and nervousness (rs=-0.92; P<.001). The simple multilevel analysis showed that for each point of happiness, nervousness decreased by 0.45 points (95% CI -0.48 to -0.42; t3=-41.7; P<.001; SE 0.01).

CONCLUSIONS: Our study reveals that depressive and anxiety symptoms do not significantly affect the variability in predicted happiness and nervousness scores. However, we observed that demographic factors, such as gender and age, play a role in emotional variability.

Embodied decisions as active inference.

PLoS computational biology, 21(6):e1013180.

Decision-making is often conceptualized as a serial process, during which sensory evidence is accumulated for the choice alternatives until a certain threshold is reached, at which point a decision is made and an action is executed. This decide-then-act perspective has successfully explained various facets of perceptual and economic decisions in the laboratory, in which action dynamics are usually irrelevant to the choice. However, living organisms often face another class of decisions-called embodied decisions-that require selecting between potential courses of actions to be executed timely in a dynamic environment, e.g., for a lion, deciding which gazelle to chase and how fast to do so. Studies of embodied decisions reveal two aspects of goal-directed behavior in stark contrast to the serial view. First, that decision and action processes can unfold in parallel; second, that action-related components, such as the motor costs associated with selecting a particular choice alternative or required to "change mind" between choice alternatives, exert a feedback effect on the decision taken. Here, we show that these signatures of embodied decisions emerge naturally in active inference-a framework that simultaneously optimizes perception and action, according to the same (free energy minimization) imperative. We show that optimizing embodied choices requires a continuous feedback loop between motor planning (where beliefs about choice alternatives guide action dynamics) and motor inference (where action dynamics finesse beliefs about choice alternatives). Furthermore, our active inference simulations reveal the normative character of embodied decisions in ecological settings - namely, achieving an effective balance between a high accuracy and a low risk of missing valid opportunities.

Competing Subclones and Fitness Diversity Shape Tumor Evolution Across Cancer Types.

bioRxiv : the preprint server for biology.

Intratumor heterogeneity arises from ongoing somatic evolution complicating cancer diagnosis, prognosis, and treatment. Here we present TEATIME (estimating evolutionary events through single-timepoint sequencing), a novel computational framework that models tumors as mixtures of two competing cell populations: an ancestral clone with baseline fitness and a derived subclone with elevated fitness. Using cross-sectional bulk sequencing data, TEATIME estimates mutation rates, timing of subclone emergence, relative fitness, and number of generations of growth. To quantify intratumor fitness asymmetries, we introduce a novel metric-fitness diversity-which captures the imbalance between competing cell populations and serves as a measure of functional intratumor heterogeneity. Applying TEATIME to 33 tumor types from The Cancer Genome Atlas, we revealed divergent as well as convergent evolutionary patterns. Notably, we found that immune-hot microenvironments constraint subclonal expansion and limit fitness diversity. Moreover, we detected temporal dependencies in mutation acquisition, where early driver mutations in ancestral clones epistatically shape the fitness landscape, predisposing specific subclones to selective advantages. These findings underscore the importance of intratumor competition and tumor-microenvironment interactions in shaping evolutionary trajectories, driving intratumor heterogeneity. Lastly, we demonstrate that TEATIME-derived evolutionary parameters and fitness diversity offer novel prognostic insights across multiple cancer types.

Mapping nonhuman cultures with the Animal Culture Database.

Scientific data, 12(1):1019.

Socially transmitted behaviors are widespread across the animal kingdom, yet there is a lack of comprehensive datasets documenting their distribution and ecological significance. Knowledge of animal behavioral traditions could be essential for understanding many species' responses to anthropogenic disturbances and further enhancing conservation efforts. Here, we introduce the first open-access database that synthesizes data on animal cultural behaviors and traditions. The Animal Culture Database (ACDB) contains descriptions of 128 behaviors including forms of vocal communication, migration, predator defense, foraging practices, habitat alteration, play, mating displays, and other social behaviors for an initial sample of 61 species. In addition to offering an open-access resource for researchers, educators, and conservationists, the ACDB represents a step toward recognizing the role of social learning in animal populations.

Range expansion during recolonization: what does animal personality have to do with it?.

Behavioral ecology : official journal of the International Society for Behavioral Ecology, 36(4):araf053.

At the edge of an ongoing expansion, pioneer individuals encounter novel ecological and evolutionary pressures that may not be experienced by conspecifics settled in long-colonized areas. Consistent behavioral differences among conspecifics (animal personality) may be important determinants of individuals' successful colonization of novel environments and range expansion. By enhancing an individual's ability to find food and shelter as well as increasing its capacity to navigate novel environments, behavioral traits such as exploration and risk-taking are thus expected to be more highly expressed in populations undergoing expansion than in established populations. We investigated among-individual variation in behaviors associated to risk-taking and exploratory tendencies in populations of small mammals during different stages of the colonization process. Using a standardized behavioral test in the field, we quantified exploration and boldness of striped field mice (Apodemus agrarius, N = 95) from six subpopulations from Germany, where they are established, and in Slovakia, where a recolonization of the area is currently in progress, and in control species bank voles (Myodes glareolus, N = 76) that shared the same habitats but were long-established at all sites. Striped field mice in the expanding populations were significantly slower in exploring the open field arena, while showing comparable levels of risk taking compared to conspecifics from established populations. No difference in behavior was detected between the populations of bank voles. Our results suggest that a slow exploration strategy might play an advantageous role in expansion processes of small mammal populations.

A survey of computational approaches for characterizing microbial interactions in microbial mats.

Genome biology, 26(1):168.

In this review, we use microbial mat communities as a general model system to highlight the strengths and limitations of current computational methods for analyzing interactions between members of microbial ecosystems. We describe the factors that make this environment have such a high degree of interaction, and we explore different categories of both laboratory and computational tools for studying these interactions. For each tool, we describe efforts to apply them to microbial mats in the past and, in the process, argue that genome-scale metabolic models have breakthrough potential for modeling microbial interactions in microbial mats.

Collective cooperative intelligence.

Proceedings of the National Academy of Sciences of the United States of America, 122(25):e2319948121.

Cooperation at scale is critical for achieving a sustainable future for humanity. However, achieving collective, cooperative behavior-in which intelligent actors in complex environments jointly improve their well-being-remains poorly understood. Complex systems science (CSS) provides a rich understanding of collective phenomena, the evolution of cooperation, and the institutions that can sustain both. Yet, much of the theory in this area fails to fully consider individual-level complexity and environmental context-largely for the sake of tractability and because it has not been clear how to do so rigorously. These elements are well captured in multiagent reinforcement learning (MARL), which has recently put focus on cooperative (artificial) intelligence. However, typical MARL simulations can be computationally expensive and challenging to interpret. In this perspective, we propose that bridging CSS and MARL affords new directions forward. Both fields can complement each other in their goals, methods, and scope. MARL offers CSS concrete ways to formalize cognitive processes in dynamic environments. CSS offers MARL improved qualitative insight into emergent collective phenomena. We see this approach as providing the necessary foundations for a proper science of collective, cooperative intelligence. We highlight work that is already heading in this direction and discuss concrete steps for future research.

The chromosomal genome sequence of the sponge Crambe crambe (Schmidt, 1862) and its associated microbial metagenome sequences.

Wellcome open research, 10:275.

We present a genome assembly from an individual Crambe crambe (Porifera; Demospongiae; Poecilosclerida; Crambeidae). The host genome sequence is 143.20 megabases in span. Most of the assembly is scaffolded into 18 chromosomal pseudomolecules. The mitochondrial genome has also been assembled and is 19.53 kilobases in length. Several symbiotic prokaryotic genomes were assembled as MAGs, including two relevant sponge symbionts, the Candidatus Beroebacter blanensis/ AqS2 clade (Tethybacterales, Gammaproteobacteria) of LMA sponges, and the widely distributed archaeal Nitrosopumilus sp. clade.

Smartphone-Supported Cognitive-Behavioral Therapy in Binge-Eating Disorder: An Exploratory Randomized Trial.

The International journal of eating disorders [Epub ahead of print].

OBJECTIVE: To assess the feasibility of a smartphone app delivering just-in-time adaptive interventions as an adjunct to cognitive-behavioral therapy (CBT) adapted to binge-eating disorder (BED), estimate its effects assuming superiority over CBT alone, and document safety and target engagement.

METHOD: A single-center, assessor-blinded, parallel feasibility study randomized adults aged 18-65 years with full-syndrome or subthreshold BED to smartphone-supported CBT (SmartCBT) or standard CBT (DRKS00024597). Both arms received 16 individual 50-min CBT sessions over 4 months. Assessments were conducted at baseline (T0), midtreatment (T1), posttreatment (T2), and 3-month follow-up (T3). Feasibility was determined regarding recruitment, attrition, dropout, adherence, assessment completion, app use, and acceptance. Further, eating disorder symptoms, mental and physical health, weight management behavior, safety, and target engagement (i.e., skill use) were assessed.

RESULTS: Over a 7-month recruitment period, 28 of 50 eligible volunteers were included and randomized 1:1 to SmartCBT or CBT. In the modified intent-to-treat sample (N = 25; SmartCBT: 13, CBT: 12), the feasibility of SmartCBT was further supported regarding attrition, dropout, adherence, treatment completion, app use, and acceptance; however, assessment completion was moderate. Clinical improvements were found in both arms, but differential results were affected by baseline differences and moderate assessment completion in the SmartCBT arm. Safety was documented, and support for target engagement was found.

CONCLUSIONS: This exploratory study provides evidence for the feasibility of app-supported CBT for BED. With few procedural refinements, the protocol can be used in a confirmatory randomized-controlled trial with long-term follow-up to evaluate efficacy and determine treatment mechanisms.

RJR Experience and Expertise

Researcher

Robbins holds BS, MS, and PhD degrees in the life sciences. He served as a tenured faculty member in the Zoology and Biological Science departments at Michigan State University. He is currently exploring the intersection between genomics, microbial ecology, and biodiversity — an area that promises to transform our understanding of the biosphere.

Educator

Robbins has extensive experience in college-level education: At MSU he taught introductory biology, genetics, and population genetics. At JHU, he was an instructor for a special course on biological database design. At FHCRC, he team-taught a graduate-level course on the history of genetics. At Bellevue College he taught medical informatics.

Administrator

Robbins has been involved in science administration at both the federal and the institutional levels. At NSF he was a program officer for database activities in the life sciences, at DOE he was a program officer for information infrastructure in the human genome project. At the Fred Hutchinson Cancer Research Center, he served as a vice president for fifteen years.

Technologist

Robbins has been involved with information technology since writing his first Fortran program as a college student. At NSF he was the first program officer for database activities in the life sciences. At JHU he held an appointment in the CS department and served as director of the informatics core for the Genome Data Base. At the FHCRC he was VP for Information Technology.

Publisher

While still at Michigan State, Robbins started his first publishing venture, founding a small company that addressed the short-run publishing needs of instructors in very large undergraduate classes. For more than 20 years, Robbins has been operating The Electronic Scholarly Publishing Project, a web site dedicated to the digital publishing of critical works in science, especially classical genetics.

Speaker

Robbins is well-known for his speaking abilities and is often called upon to provide keynote or plenary addresses at international meetings. For example, in July, 2012, he gave a well-received keynote address at the Global Biodiversity Informatics Congress, sponsored by GBIF and held in Copenhagen. The slides from that talk can be seen HERE.

Facilitator

Robbins is a skilled meeting facilitator. He prefers a participatory approach, with part of the meeting involving dynamic breakout groups, created by the participants in real time: (1) individuals propose breakout groups; (2) everyone signs up for one (or more) groups; (3) the groups with the most interested parties then meet, with reports from each group presented and discussed in a subsequent plenary session.

Designer

Robbins has been engaged with photography and design since the 1960s, when he worked for a professional photography laboratory. He now prefers digital photography and tools for their precision and reproducibility. He designed his first web site more than 20 years ago and he personally designed and implemented this web site. He engages in graphic design as a hobby.

This book introduces readers to ecological informatics as an emerging discipline that takes into account the data-intensive nature of ecology, the valuable information to be found in ecological data, and the need to communicate results and inform decisions, including those related to research, conservation and resource management. At its core, ecological informatics combines developments in information technology and ecological theory with applications that facilitate ecological research and the dissemination of results to scientists and the public. Its conceptual framework links ecological entities (genomes, organisms, populations, communities, ecosystems, landscapes) with data management, analysis and synthesis, and communicates new findings to inform decisions by following the course of a loop. In comparison to the 2nd edition published in 2006, the 3rd edition of Ecological Informatics reflects the significant advances in data management, analysis and synthesis that have been made over the past 10 years, including new remote and in situ sensing techniques, the emergence of ecological and environmental observatories, novel evolutionary computations for knowledge discovery and forecasting, and new approaches to communicating results and informing decisions.
