A laser-etched, energy absorbing, water wicking metal surface, continually angled directly at the sun, provides a cheap, efficient way to purify water from sunlight. The technology was developed by the lab of Chunei Guo at the University of Rochester. Credit: H.M. Cao/University of Rochester By etching metal with ultrashort laser […]

Two satellite images show vegetation change from fog in two areas of the Namib desert. The left image shows the areas during periods of lower fog; the right image shows the areas during periods of higher fog. Greener areas inside the squares indicate vegetation greening.

Percentages represent fraction of the global cultivated area in each category. Shading indicates croplands affected by blue water scarcity (BWS) that can be sustainably irrigated with deficit irrigation. These areas are then reclassified as suitable for sustainable irrigation [i.e., with no blue water scarcity (NO BWS)], considering different deficit irrigation […]

A new U.S. Supreme Court ruling puts groundwater science at the center of decisions about how to regulate water pollution. Today, in a closely watched case with extensive implications, the court ruled 6 to 3 that the federal Clean Water Act applies to pollution of underground water that flows into nearby lakes, […]

The research, led by Oregon State University’s Catalina Segura, is an important step toward […]

Water, water, everywhere. (Image: © Shutterstock) What did Earth look like 3.2 billion years ago? New evidence suggests the planet was covered by a vast ocean and had no continents at all. Continents appeared later, as plate tectonics thrust enormous, rocky land masses upward to breach the sea surfaces, scientists recently reported. They found […]
