Effective emission mitigations are currently hindered by the largely unresolved ecophysiological controls of coexisting N2O-converting metabolisms in complex communities. To address this, we used biological wastewater treatment as a model ecosystem and combined long-term metagenome-resolved metaproteomics with ex situ kinetic and full-scale operational characterization over nearly 2 years. By leveraging the evidence independently obtained at multiple ecophysiological levels, from individual genetic potential to actual metabolism and emergent community phenotype, the cascade of environmental and operational triggers driving seasonal N2O emissions has ultimately been resolved. We identified nitrifier denitrification as the dominant N2O-producing pathway and dissolved O2 as the prime operational parameter, paving the way to the design and fostering of robust emission control strategies. This work exemplifies the untapped potential of multi-meta-omics in the mechanistic understanding and ecological engineering of microbiomes towards reducing anthropogenic impacts and advancing sustainable biotechnological developments. Nitrous oxide is one of the main greenhouse gases emitted during biological wastewater treatment. This long-term multi-meta-omics analysis of a wastewater treatment plant identifies the main causes of nitrous oxide emissions and actionable mitigation strategies.","PeriodicalId":74252,"journal":{"name":"Nature water","volume":"3 5","pages":"590-604"},"PeriodicalIF":24.1,"publicationDate":"2025-05-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12098122/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144144800","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the implementation of catalytic technologies is hindered by the large variety of PFAS compounds requiring treatment, a limited understanding of catalytic PFAS-degradation mechanisms and pathways, poor catalytic process selectivity towards PFAS over other water constituents, and a lack of appropriate methods to compare catalytic treatment options. Here we recommend strategies to overcome these challenges, including pretreating complex PFAS mixtures to simplify the design space of catalytic treatments, engineering catalytic systems and catalyst surfaces for selectivity, and developing holistic figures of merit that consider defluorination efficiencies and life-cycle costs to push forward the research, development and deployment of catalytic technologies for PFAS mineralization. Research needs to realize these designs and include a better understanding of the reaction mechanisms, catalyst surface engineering and treatment process design.

Thermodiffusion, the migration of solutes driven by temperature gradients, has recently emerged as a promising alternative mechanism for desalination. Thermodiffusive desalination is a thermal desalination method that operates entirely in the liquid phase without membranes or other functional materials. We previously proposed the Burgers cascade—a multichannel system designed to amplify modest thermodiffusive concentration differences—and provided theoretical predictions of its performance. Here we present the first experimental demonstration of thermodiffusive desalination using the Burgers cascade, achieving significant improvements in separation. We show that natural seawater and brine can be effectively purified or concentrated using this approach. Our results reveal that nonlinear temperature profiles and developing concentration flows in the channels of the liquid Burgers cascade enhance the yield flow rate approximately 40-fold, while partial thermal insulation of the Burgers cascade greatly improves energy efficiency. Thermodiffusive (de)salination is energetically more favourable for brine concentration than desalination. This work brings us closer to the realization of thermodiffusive water treatment and has wider implications for species separation in liquid systems using the Burgers cascade. Thermodiffusive desalination is a water treatment method that does not rely on membranes. Here a multichannel device called a liquid Burgers cascade is shown to enhance performance for brine concentration and seawater desalination.","PeriodicalId":74252,"journal":{"name":"Nature water","volume":"3 5","pages":"617-631"},"PeriodicalIF":24.1,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.comhttps://www.nature.com/articles/s44221-025-00428-5.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145122804","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

During the pandemic phase of COVID-19, there was widespread awareness of the importance of hygiene for disease control, and demand was high for action to improve access to hygiene materials. However, those efforts have faltered, and, in general, interventions to improve hygiene at scale have shown limited success in delivering sustained behaviour change and health impact. We convened experts in hygiene across sectors (for example, health, education and agriculture) and disciplines (for example, academia, policy and practice) in Dakar, Senegal, to discuss the critical barriers and opportunities for researching, developing and implementing systems-level hygiene interventions and promote learning across sectors, with a focus on systems approaches. We report what is needed to achieve catalytic improvements in hygiene in low-income settings and the Global South, with an emphasis on ‘hygienic systems’ that target all relevant hygiene moments—a set of associated behaviours at a given time and place with high pathogen exposure risk—and their enabling conditions and pre-conditions. This focus beyond individual behaviours will require removing silos across sectors and ministries, the generation of relevant evidence for policymakers and the localization of guidance. Despite considerable attention, hygiene systems and practices remain inadequate where they are most needed. New thinking and innovative approaches are needed to develop, implement and evaluate hygienic systems to reduce pathogen exposure in high-transmission settings.","PeriodicalId":74252,"journal":{"name":"Nature water","volume":"3 5","pages":"518-524"},"PeriodicalIF":24.1,"publicationDate":"2025-04-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145122828","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Improving people’s subjective sanitation experiences is also important but rarely rigorously measured. The Sanitation-related Quality of Life index (SanQoL-5) combines answers to five simple questions (disgust, privacy, disease risk, shame and safety) into an overall score ranging from 0 to 1. Here we evaluated the validity and reliability of SanQoL-5 by interviewing 6,165 people across rural and urban areas of six countries: Ethiopia, India, Kenya, Malawi, Mozambique and Zambia. We found good evidence for construct validity, with support (P < 0.05) for 87% of hypothesized associations between SanQoL-5 and toilet quality characteristics. In 75 intercountry comparisons, only 9% of instances showed evidence of meaningful differential item functioning, suggesting good cross-cultural comparability. SanQoL-5 conformed to expectations in item response theory models, and we found evidence of convergent, discriminant and known groups validity.

However, existing microbial risk assessment frameworks often lack breadth and coherence. Here, to address this constraint, we developed a cellular spike-in (including one Gram-positive bacterium (G+) and one Gram-negative bacterium (G−)) method that enables absolute quantification of microorganisms in multiple environmental compartments (for example, wastewater, river water and marine water). This method was thoroughly evaluated for consistency, accuracy, feasibility and applicability. Furthermore, we investigated potential biases that might arise from DNA extraction to sequencing under different cell lysis conditions and, importantly, demonstrated that this spike-in absolute quantification method could correct such biases. We then applied this method to various samples to determine the absolute abundance (concentration) of microorganisms, pathogens and antibiotic resistance genes. On the basis of the results, we evaluated the removal efficiencies in terms of pathogens and antibiotic resistance genes in five wastewater treatment plants with different operational modes (for example, chemically enhanced primary treatment, secondary treatment, tertiary treatment and membrane bioreactor). Finally, we developed a risk assessment framework that simplifies complex absolute quantification data into accessible scores, enabling a comprehensive microbial risk evaluation and comparison across diverse environments. This analytical workflow could facilitate informed policymaking and decision-making by authorities based on risk assessment levels, advancing efforts to safeguard public health. A cellular spike-in metagenomic method for absolute quantification of microorganisms in the aquatic environment is used to develop a risk assessment framework to support informed water quality management and policy decisions.","PeriodicalId":74252,"journal":{"name":"Nature water","volume":"3 4","pages":"473-485"},"PeriodicalIF":24.1,"publicationDate":"2025-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145122991","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
