To gaze at the stars is human. To be able to see them in 3D detail is very nearly divine.
Divine vision is what the James Webb Space Telescope has granted Earthbound scientists in a new near-infrared, detailed image of Cassiopeia A (Cas A), a stellar remnant—the clouds of gas, dust and other material left behind when a star dies. Danny Milisavljevic, assistant professor of physics and astronomy in Purdue University’s College of Science, studies supernova remnants and leads a year one research team on the JWST examining Cas A.

Eating lots of fats increases the risk of metabolic disorders, but the mechanisms behind the problem have not been well understood. Now, University of California, Irvine biologists have made a key finding about how to ward off harmful effects caused by a high-fat diet. Their study appears in Nature Communications.

The UC Irvine research centered on a protein complex called AMPK, which senses the body’s nutrition and takes action to keep it balanced. For example, if AMPK detects that glucose is low, it can boost lipid breakdown to produce energy in its place...

Like batteries, fuel cells produce energy through an electrochemical process. Unlike batteries, they don’t run down or require recharging. However, the potential advantages of fuel cells are offset by challenges that include cost, performance and durability.
