While blue space has been linked to metabolic health, research has primarily focused on water quantity rather than quality. This study finds that lower water coverage and higher exposure to black-odorous water increase risk of metabolic syndrome.

Antibiotics are increasingly being detected in water systems worldwide. Long-term exposure to low-dose antibiotics causes Escherichia coli to remodel its extracellular matrix, limiting antibiotic access to the bacterial cells.

A fluorochromic metal–organic framework sensor enables real-time visualization of thorium adsorption and exhibits a higher selectivity than other tetravalent cations.

As the next UN Water Conference approaches, the world must look beyond SDG6 and short-term deadlines. A broader, more adaptive vision is essential to address the political, social, and environmental realities of water.

Groundwater, enhanced through managed aquifer recharge, is crucial for alleviating water stress. This study demonstrates that isotopic tracers, including tritium from nuclear power plant effluents, can be used to map groundwater flow in Swiss alluvial systems, revealing insights into groundwater travel time distributions and informing sustainable groundwater management globally.

A multifunctional adsorbent, composed of copper-doped polydopamine-functionalized magnetic silica, enables the simultaneous removal and on-site detection of label-free nano- and microplastics.

Electrochemical nitrate reduction can simultaneously remove pollutants and produce ammonia but is often limited by hydrogen side reactions. This study shows that nanoconfined CuCo catalysts enable a proton-coupled electron transfer pathway that delivers highly selective, efficient and stable ammonia synthesis.

This study presents an electrolyte-free electrochemical system that leverages dual electrocatalytic zones to effectively remove a wide range of recalcitrant pollutants across various water matrices, including low-conductivity organic wastewater.

An electrothermal fluorination methodology has been developed to transform granular activated carbon-sorbed aqueous film-forming foam waste into graphene and a fluorinating reagent, subsequently enabling lithium recovery from brine sources.
