Enzyme shown to regulate inflammation and metabolism in fat tissue

New research in mice and humans suggests that an enzyme called SNRK suppresses inflammation in obesity-related “white fat” while increasing metabolism in heat-producing “brown fat,” making SNRK an intriguing target in the battle against obesity.

Clay minerals on Mars may have formed in primordial steam bath

New research suggests that the bulk of clay minerals on Mars could have been formed as the planet’s crust cooled and solidified, not by later interactions with water on the surface as has long been assumed.

Gravitational waves could shed light on the origin of black holes

The detection of gravitational waves has given astronomers a new way of looking at the universe, and a new study shows how these ripples in the fabric of spacetime might confirm or rule out the existence of a certain type of black hole.

New research suggests Mercury’s poles are icier than scientists thought

A Brown University study identifies three large surface ice deposits near Mercury’s north pole, and suggests there could be many additional small-scale deposits that would dramatically increase the planet’s surface ice inventory.
