A dryland ecosystem in Northern California shows decreasing soil moisture but little changes in surface water availability. Credit: Columbia Engineering New Columbia Engineering study — first to investigate the long-term effect of soil moisture-atmosphere feedbacks in drylands — finds that soil moisture exerts a negative feedback on surface water availability […]

This 3D model of a polymer desalination membrane shows water flow — the silver channels, moving from top to bottom — avoiding dense spots in the membrane and slowing flow.

Researcher Rachel Slank works with the university’s Mars chamber. Credit: Whit Pruitt, University of Arkansas Researchers considered more variables and took global weather patterns into account to create maps of where water might be found. Water on Mars, in the form of brines, may not be as widespread as previously thought, […]

A solution to the growing clean drinking water availability problem is direct solar steam generation technology, which can remove harmful soluble pollutants from water. Credit: Lei Miao from SIT Scientists review some of the research behind a technology that could cauterize a growing global drinking water crisis. A nascent but […]

Researchers combined data on brine evaporation […]

Odds of exceeding maximum contaminant levels were significantly greater for water systems in the Southwest and serving Hispanic communities. A new national study of public water systems found that arsenic levels were not uniform across the U.S., even after implementation of the latest national regulatory standard. In the first study […]

Here on Earth, geologists seek out deep channels into Earth’s rock, carved over the ages by flowing water. The exposed rock walls are like a visual timeline of a region’s geological history. On Mars, the surface water is long gone. But it flowed long enough to expose layers of rock […]

Mars suffered an early bombardment before settling in to a prolonged calm, a new meteorite record indicates. DETLEV VAN RAVENSWAAY/SCIENCE SOURCE It was a tough fundraising pitch: Martin Bizzarro, a cosmochemist at the University of Copenhagen, needed some $500,000 to buy—and then grind up—material from one of the oldest and […]
