This past winter, the Rocky Mountains experienced an historic snow drought, a worrying development for the tens of millions of people in the arid American West who depend on snowmelt for water. Now, a new study in the journal ...

Batteries that use solid metal as their charge-carrying electrolyte could potentially be a safer and far more energy-dense alternative to lithium-ion batteries. Unfortunately, these solid-state batteries have been plagued ...

Chronic inflammation can raise a person's risk of cancer, and a new study reveals key details about how that might happen in the gut and points to better ways to identify and reduce risk. Scientists at the Broad Institute ...
