Here we show that the concentration of the flow within the water year is also changing and that these shifts affect the division of water among water right holders, especially under the prior appropriation doctrine. To measure the spread of a stream’s hydrograph around its centre of timing, we deployed the standard deviation of timing (SDoT). The SDoT exhibits similar patterns to other streamflow variability measures, especially in snowmelt-dominated systems, but is unique because it is more sensitive to when the variable flows occur. It is predominantly decreasing in the Western USA and increasing in the Eastern USA, showing more locally significant trends at reference gauges than streamflow quantity or centre of timing. The relationships between SDoT and both precipitation and temperature vary across the USA. An empirical case study shows that a narrower runoff distribution favours junior water rights holders to receive a greater share of the runoff. Shifting seasonal water availability and variation in societal demands for surface water challenge water resource management. This study reveals that where streamflow timing becomes more narrowly concentrated, junior water right holders could benefit with greater shares of water within a priority system like that applied across much of the Western USA.","PeriodicalId":74252,"journal":{"name":"Nature water","volume":"4 6","pages":"742-751"},"PeriodicalIF":30.7,"publicationDate":"2026-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148292569","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}

However, conventional materials discovery processes remain slow and largely serendipitous, hindered by the ‘dark matter’ within complex purification mechanisms and stringent electronic structure requirements. Here we present ECOMATS, a multi-agent artificial intelligence system for water purification applications, which integrates expert-validated knowledge graphs with seven fine-tuned large language models to autonomously design peroxymonosulfate-activating catalysts for advanced oxidation processes. ECOMATS uses a five-dimensional evaluation framework and a triple-agent blind review system with consistency-based score fusion to improve prediction reliability. Using this integrated approach, we identified several promising catalyst candidates, with theoretical calculations showing that their d-band centres fall within the optimal range for peroxymonosulfate activation. A representative catalyst, (FeTCPP)Co2(MeIm)2, where TCPP is tetrakis(4-carboxyphenyl)porphyrin and MeIm is 2-methylimidazole, was synthesized and showed exceptional performance, achieving 90.5% degradation of perfluorooctanoic acid within 5 min, surpassing most reported analogues. It also maintained robust activity across a broad pH range of 3–11 and consistently removed contaminants in practical wastewater samples from 31 provinces across China, demonstrating practical effectiveness. This work establishes a paradigm of accelerated and application-oriented material discovery, advancing sustainable water purification. This work introduces an AI system that can independently design highly effective water purifying catalysts—validated both in theory and real wastewater samples—showing how AI can dramatically speed up the discovery of materials for cleaner, safer water.","PeriodicalId":74252,"journal":{"name":"Nature water","volume":"4 5","pages":"630-642"},"PeriodicalIF":24.1,"publicationDate":"2026-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148003751","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 introduce recyclable magnetic biohybrid nanonets (LAF-IONPs), engineered through in situ growth of iron oxide nanoparticles (IONPs) on lysozyme amyloid fibrils (LAFs). Stabilized by synergistic interfacial interactions, LAF-IONPs efficiently capture NPs over a wide range of sizes (30–1,000 nm) and chemical compositions across environmentally relevant concentrations and conditions (pH 7–9, high salinity and co-existing pollutants). The superior removal efficiency arises from magnetic active motion and abundant fibril binding sites. Remarkably, LAF-IONPs achieved 98.0–99.9% NPs removal from various real water samples and maintained >95% efficiency over 100 recycling cycles when using a custom alternating magnetic field system. Critically, LAF-IONPs treatment reduced in vivo NPs bioaccumulation by 91.5%. This work establishes a blueprint for designing recyclable biohybrid adsorbents for active, efficient and sustainable removal of NPs and potentially other emerging contaminants. Nanoplastics are persistent water contaminants that evade conventional removal methods.

Here, inspired by termite mound thermoregulation, we present a four-tier water-recovery architecture to bridge this gap. The primary tier utilizes a heterostructured microsphere coating to achieve a capillary-driven nucleation rate of 33.6 g m−2 min−1, while enabling 1.7 °C of radiative sub-dewpoint cooling via gradient-refractive index spines. The secondary tier integrates an inverted-pyramid composite that acts as a mechanical shield to enlarge the heat-transfer area. Subsequently, the tertiary tier establishes a radiative cooling-dominant gas–liquid heat-transfer scheme with a net power of 133.7 W m−2. Finally, the quaternary tier employs biomimetic flow channels to suppress vapour dispersion and sustain a self-sustaining ‘condensation–radiative cooling–recondensation’ cycle. Operating passively, the system achieves a recovery rate of 41.6 kg m−2 day−1 and an 83% retention rate. For a 300-MW plant, this yields 2.7 × 108 tonnes of annual water savings, meeting the domestic needs of 2.2 million households. Industrial cooling towers release large quantities of water vapour that remains largely unutilized, despite its potential as a recoverable resource. This study demonstrates a passive, biomimetic multi-tier system to achieve high-rate water recovery with substantial large-scale savings potential.","PeriodicalId":74252,"journal":{"name":"Nature water","volume":"4 6","pages":"788-801"},"PeriodicalIF":30.7,"publicationDate":"2026-04-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148292554","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}

Our study in Beira, Mozambique, assessed the impact of water infrastructure improvements in neighbourhoods with or without a newly replaced water service line. We collected data from 642 households on microbial contamination in stored and source water, water access and satisfaction with water service. The intervention reduced the presence of any E. coli contamination by 33% in household source water and by 14% in stored water. Regardless of intervention status, having a direct household connection to the piped water network (versus none) was associated with 24% lower prevalence of E. coli in source water but no difference in stored water. Intervention households and households with a direct connection had better water access and higher satisfaction. These findings suggest that urban water supply interventions can improve access to a safe water supply, but improvements may be compromised by water storage practices due to water intermittency. Urban water systems in low-income cities often face contamination risks and unreliable supply, motivating evaluations of infrastructure upgrades. An assessment of the impact of water service line replacements on water quality and access in Beira, Mozambique, reveals reduced source water contamination and improved access.","PeriodicalId":74252,"journal":{"name":"Nature water","volume":"4 5","pages":"599-609"},"PeriodicalIF":24.1,"publicationDate":"2026-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148003753","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, using global hydrological observations from over 4,000 catchments and coupled land–atmosphere simulations, we find that nearly half of greening catchments exhibit simultaneous increases in evapotranspiration and streamflow, particularly in semi-arid regions. Based on the case of the Chinese Loess Plateau where the largest revegetation activity ever occurred on Earth, we show that conventional offline approaches neglect vegetation–atmosphere feedbacks, underestimating greening-induced evapotranspiration by more than 50% and misrepresenting water-availability trends. Greening reduces surface albedo and alters energy partitioning, intensifying net radiation, convection and the atmospheric efficiency of converting moisture into precipitation. This enhanced precipitation supply offsets evaporative losses and sustains or increases streamflow. Consistent results across four other global greening hotspots confirm that albedo-driven energy-mediated feedbacks are a dominant mechanism linking greening to water availability. These findings underscore the need to integrate these feedbacks into restoration and management frameworks for sustainable water and ecosystem outcomes. Vegetation greening is traditionally thought to increase evapotranspiration and reduce streamflow, posing a challenge for balancing ecosystem restoration with water supply. This study reveals that greening can enhance both evapotranspiration and streamflow, particularly in semi-arid regions through albedo-driven, energy-mediated increases in the efficiency with which atmospheric moisture is converted into precipitation.","PeriodicalId":74252,"journal":{"name":"Nature water","volume":"4 5","pages":"559-570"},"PeriodicalIF":24.1,"publicationDate":"2026-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148003758","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}
