Here we performed an integrative study investigating the role of environmental EVs in shaping microbial community assembly in the Xinglinwan Reservoir. By combining genome-scale metabolic models and multi-omics of field EVs, we found that EVs mediated metabolite exchanges mainly through carrying amino acids, disaccharides, carbohydrate-active enzymes (CAZymes) and signals. EVs can facilitate the growth of amino acid auxotrophic strains. Moreover, EVs act as an external reservoir of functional traits, potentially reinforcing stochastic assembly processes and conferring functional redundancy to the ecosystem. Collectively, our integrative data demonstrate that EV-mediated metabolic exchange is an auxiliary mechanism supplementing classical nutrient transport in aquatic environments. EVs emerge here as a significant, distinct vector in biogeochemical cycling, offering a critical layer for resolving complex natural microbial interactions. Microorganisms release extracellular vesicles, but their ecological roles in natural environments remain unclear. A year-long multi-omics study reveals that environmental extracellular vesicles mediate metabolite exchange central to carbon and nitrogen cycling while stabilizing microbial communities.","PeriodicalId":74252,"journal":{"name":"Nature water","volume":"4 4","pages":"466-480"},"PeriodicalIF":24.1,"publicationDate":"2026-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147735099","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}

Here we show the complete mineralization of TFA under ambient conditions via previously undescribed oxidative/reductive tandem reactions. Contrary to the conventional defluorination, the efficacy is attributed to the overlooked nucleophilic oxygen radical anion (O•−, deprotonated form of hydroxyl radical) oxidation with a rate of 5.1 × 107 M−1 s−1, 50-fold higher than that with the hydrated electron (eaq−). Electron pulse radiolysis experiments, combined with molecular simulations, were used to characterize the generation of CF3CO32−• intermediates and their subsequent dissociation. The total transformation to F− and CO32− is further achieved by eaq− reduction. Beyond TFA, this intriguing oxidative/reductive tandem strategy also enables mineralization of perfluorobutanoic acid, perfluorohexanoic acid and perfluorooctanoic acid, demonstrating broad applicability across perfluoroacids and halogenated substrates. Its industrial viability is underscored by the use of commercial electron beam irradiation, which achieves rapid defluorination at rates up to 0.27 mol l−1 h−1. These findings describe a promising role for the O•−/eaq− tandem pathway for the remediation of short-chain per- and polyfluoroalkyl substances and the degradation of organic halides. This study reveals an effective way to achieve mineralization of short-chain per- and polyfluoroalkyl substances by pairing two reactive species that work together under mild conditions, offering a powerful and scalable strategy for remediating persistent pollutants.","PeriodicalId":74252,"journal":{"name":"Nature water","volume":"4 5","pages":"621-629"},"PeriodicalIF":24.1,"publicationDate":"2026-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148003762","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}

Here urea additions at ecologically relevant rates tripled summer phytoplankton abundance in replicate agricultural reservoirs with significant responses by most eukaryotic algae, but not cyanobacteria or their toxins. Mass budgets reveal that fertilized reservoirs did not become limited by phosphorus due to its continuous release from sediments. Further, most added nitrogen did not accumulate in reservoirs but was lost to the atmosphere, probably as NH3. Sub-continental spatial analysis shows that study reservoirs are characteristic of shallow water bodies within Canada’s largest agricultural region, where >40% of surface waters are vulnerable to degradation by urea. Similar degrees of water quality loss by urea are expected in other global agricultural regions (for example, China, India, North America) where elevated urea use interacts with phosphorus-rich surface waters to induce extreme eutrophication. Urea, the most widely used nitrogen fertilizer, has unknown impacts on freshwater ecosystems. This study demonstrates that urea additions in Canadian prairie agricultural reservoirs triple phytoplankton abundance without increasing cyanobacterial toxins, revealing considerable nitrogen loss to the atmosphere and highlighting potential global water quality degradation in phosphorus-rich agricultural regions.","PeriodicalId":74252,"journal":{"name":"Nature water","volume":"4 6","pages":"752-763"},"PeriodicalIF":30.7,"publicationDate":"2026-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148292556","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}

A persistent challenge is separating lithium from the chemically similar sodium and potassium ions. Inspired by sodium–potassium cotransporter proteins, which regulate ion transport through selective pores, we prepared a metal–organic framework (MOF)-based ion-selective glass composite (ISGC) membrane via melt quenching of glassable zeolitic imidazolate framework 62 (ZIF-62) with thermally stable ZIF-8. The resulting confined sub-nanometre channels discriminated monovalent cations and exhibited high selectivity through coupled dehydration–rehydration effects and weak ion–MOF interactions, as confirmed by molecular dynamics simulations. In binary mixtures, the ag[(ZIF-62)0.7(ZIF-8)0.3] membranes achieved K+/Li+ and Na+/Li+ selectivities of 185 and 53.3 at a 1:1 feed ratio. Notably, even at a 10:1 ratio (excess of K+), the K+/Li+ selectivity remained ~10. In multi-ion brines, selectivity was further enhanced, reaching 410 for K⁺/Li⁺ and 80 for Na⁺/Li⁺. Notably, we scaled up laboratory membranes into robust disc–tube modules compatible with crossflow operation, which enriched lithium from synthetic salt-lake brines to 64.6 g l−1 and enabled direct precipitation of battery-grade Li2CO3 at an energy input of only 1.02 kWh kg−1. By bridging molecular-level ion discrimination with scalable engineering, this work positions MOF-ISGC as a transformative platform for sustainable lithium recovery and selective ion separations in water and energy systems. This study introduces a new membrane inspired by natural ion-transport proteins that can selectively pull lithium out of salty, lithium-poor waters with exceptional efficiency, and demonstrates that the technology can be scaled up to produce battery-grade lithium using very little energy.","PeriodicalId":74252,"journal":{"name":"Nature water","volume":"4 5","pages":"643-655"},"PeriodicalIF":24.1,"publicationDate":"2026-04-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148003746","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}

Here we present a global assessment based on in situ observations from ~480,000 coastal monitoring locations. From 1990 to 2024, 21% of gridded coastal areas show statistically detectable rising or falling groundwater-level trends with magnitudes ≥0.1 m yr−1 and with declines becoming more frequent in the last 9 years. More pronounced changes are observed for deeper water tables (ρs = 0.63), in arid settings (ρs = 0.56) and in some rural areas. Seawater intrusion susceptibility is higher where seaward freshwater discharge is weak or where hydraulic gradients reverse landward, leaving limited hydraulic resistance to seawater intrusion. Extrapolating observed trends suggests that these conditions mostly persist (93.4%), while 3.5% newly emerge and 3.1% stabilize (gradients strengthen seaward). The results provide global evidence for prioritizing monitoring and management of coastal groundwater at risk of salinization.

Whereas eutrophication and climate change can enhance cyanobacterial growth rates, MC concentrations do not always increase with biomass. This unpredictability stems from a dynamic equilibrium between MC production and degradation, a process governed by complex interactions among physiological traits, microbial communities and ecological feedbacks that are still poorly understood. This Review synthesizes emerging insights into how MCs may shape cyanobacterial niche space, from predator–prey dynamics to biogeochemical cycling, to favour bloom persistence. We evaluate current removal strategies, highlighting that although advanced treatment technologies exist, most are impractical at ecosystem scales. Constructed wetlands present a more scalable solution, yet the biotic and abiotic processes that govern their effectiveness require further elucidation. Finally, we identify critical knowledge gaps and outline research priorities that are essential for improving MC prediction and mitigation in a rapidly changing world. Microcystins are cyanobacterial toxins that remain a global threat to freshwater health and function despite decades of study.

While the coupling between economic growth and environmental burdens has been widely investigated from the perspective of pollution, greenhouse gas emissions and climate warming, the relationship between economic development and human appropriation and use of water resources remains under-investigated. Here we examine the hydrologic impacts of growth through the lens of the food–energy–water nexus. We analyse major decoupling mechanisms associated with the spatial and temporal displacement of hydrologic impacts and technological efficiency. We highlight the limitations inherent to such mechanisms, as they achieve only local, temporary or relative decoupling, often by redirecting, but not reducing, the burden on water resources. We point out some promising decoupling pathways associated with new emerging trends in consumption habits and other alternative approaches to moderating consumption. Economic growth is associated with an increase in natural resource extraction, energy production and waste accumulation, and a growing demand for commodities and services, enhancing human pressure on global water resources. This Perspective addresses the hydrologic impacts of economic growth and critically analyses decoupling mechanisms associated with spatial and temporal displacement, the adoption of technology and the moderation of consumption.","PeriodicalId":74252,"journal":{"name":"Nature water","volume":"4 4","pages":"423-430"},"PeriodicalIF":24.1,"publicationDate":"2026-04-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147735095","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}
