Study finds potentially dangerous levels of arsenic in California prison drinking water

Credit: CC0 Public Domain Ten years after the state of California recognized the human right to water, hundreds of thousands of residents still rely on drinking water that contains dangerous levels of contaminants, including the highly toxic mineral arsenic. Many of them live in low-income and rural communities that struggle to afford the necessary infrastructure … Read more

Without Water and Life, Geology on Mars is Driven by the Wind

On Earth, we all know what changes our landscapes: water and wind erosion, tectonic activity, and volcanism. Today on Mars, wind-driven erosion is hard at work. Wind is an inexorable sculptor everywhere. And, it might have created places where planetary scientists and astrobiologists hunt for traces of primordial Martian life today. The Work of the … Read more

There Could be as Many Water Worlds as Earths in the Milky Way

On July 12th, 2022, NASA released the first images acquired by the James Webb Space Telescope, which were taken during its first six months of operation. Among its many scientific objectives, Web will search for smaller, rocky planets that orbit closer to their suns – especially dimmer M-type (red dwarf) stars, the most common in … Read more

Climate change is affecting drinking water quality

The Rappbode reservoir in the Harz region is surrounded by forests and is the largest drinking water reservoir in Germany. Credit: André Künzelmann/UFZ Heat waves, drought, floods, forest fires—the consequences of climate change are increasing and are changing our environment. A prime example is the countryside in the catchment area for the Rappbode reservoir in … Read more

Unveiling how water and ions impact chemical reactivities at solid-aqueous interfaces

Getting catalysts to play your tune with the help of water and water-borne species. Credit: Chinese Journal of Catalysis Solid-aqueous interfaces are ubiquitous and essential in a diverse range of natural and man-made systems and processes, from mineral formation, rock weathering and metal corrosion, to the intricate functioning of biological membranes and ion channels.

Researchers quantify the amount of energy that plants use to lift water on a global scale

A stand of quaking aspens pump water up to their canopies in southwestern Colorado. Credit: Leander Anderegg Every day, about one quadrillion gallons of water are silently pumped from the ground to the treetops. Earth’s plant life accomplishes this staggering feat using only sunlight. It takes energy to lift all this liquid, but just how … Read more

Researchers develop new technique to keep drinking water safe using machine learning

Credit: CC0 Public Domain Waterborne illness is one of the leading causes of infectious disease outbreaks in refugee and internally displaced persons (IDP) settlements, but a team led by York University has developed a new technique to keep drinking water safe using machine learning, and it could be a game changer. The research is published … Read more

Keeping bacteria at bay in Hawaiian water bodies

The research team determined levels of the different bacteria in the samples. Credit: Maria Steadmon During heavy rains, Hawaii’s streams, rivers, and nearshore waters change on microscopic levels. Bacteria in these aquatic systems increase, … Read more

New Perseverance Rock Samples Were Altered by Water. They’ll be Coming Back to Earth in the Sample Return Mission

The Perseverance rover is enjoying a bit of a winning streak lately! For the past year and a half, the rover has been exploring the Jezero crater on Mars to learn more about the planet’s past. As part of this mission, Perseverance is obtaining samples of Martian rock and soil that it will set aside … Read more
