Nature Water, Published online: 06 May 2026; doi:10.1038/s44221-026-00641-w Urea is the world’s most widely used nitrogen fertilizer. Elevated urea use can induce detrimental eutrophication of shallow surface waters in agricultural regions, accelerating water quality deterioration globally in these regions.

Nature Water, Published online: 05 May 2026; doi:10.1038/s44221-026-00642-9 Crop models increasingly project that irrigation can offset agricultural losses from climate change, informing major adaptation investments worldwide. Yet these models may systematically overestimate irrigation’s protective capacity because the representation of how irrigation alters crop thermal environments remains inco…

Nature Water, Published online: 05 May 2026; doi:10.1038/s44221-026-00646-5 Endocrine-disrupting progestogens pose risks to ecosystems through their biological activity. A chemoproteomics study shows that many phytoplankton species can transform these chemicals into forms that may be even more biologically active, potentially increasing ecological risk.

Nature Water, Published online: 01 May 2026; doi:10.1038/s44221-026-00640-x Water environments are pivotal in the spread of antimicrobial resistance, acting as conduits for antibiotics and resistance genes. Here, the authors explore the dual role of inactivating antibiotic resistance genes, highlighting their ecological benefits and risks, and propose strategies to enhance ecosystem resilience wh…

Nature Water, Published online: 01 May 2026; doi:10.1038/s44221-026-00638-5 Urbanization is reshaping microbial ecology within wastewater treatment systems. This study reveals that urbanization drives microbial homogenization and that reduced diversity is linked to poorer wastewater treatment performance and stability.

Nature Water, Published online: 30 April 2026; doi:10.1038/s44221-026-00637-6 Catalytic technologies play a pivotal role in wastewater treatment, yet identifying high-performance catalysts through conventional approaches remains challenging. A multi-agent artificial intelligence system has been developed to enable application-oriented catalyst discovery by coordinating tasks typically distributed…

Nature Water, Published online: 30 April 2026; doi:10.1038/s44221-026-00639-4 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 applie…

Nature Water, Published online: 30 April 2026; doi:10.1038/s44221-026-00634-9 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.

Nature Water, Published online: 23 April 2026; doi:10.1038/s44221-026-00643-8 Microcystin risk cannot be inferred from cyanobacterial biomass alone. Understanding toxin production, persistence and degradation across scales is essential if freshwater management is to move from bloom response to anticipatory protection.

Nature Water, Published online: 23 April 2026; doi:10.1038/s44221-026-00620-1 Nanoplastics are persistent water contaminants that evade conventional removal methods. Magnetic biohybrid nanonets are found to capture up to 99.9% of them, remain highly recyclable and greatly reduce in vivo accumulation.
