The MacArthur Foundation has just announced its latest batch of 20 fellows. Among the recipients of the $800,000 "no-strings-attached" fellowships are researchers who were recognized for their work at the intersection of science and justice.

Stories of science funding being cut, labs shutting down and scientists losing jobs have flooded the media under Trump's administration. These six graphics show how those changes have affected U.S. biomedical research.

Scientists have found a species they've named the fire amoeba, which is capable of reproducing at 145°F and continuing to move up to temperatures of 147°F — a record for complex eukaryotic life.

Neuroscientists have made a major advance in modeling the human brain in mice, offering a new way to study conditions like cerebral palsy. Ethicists ask if it changes how these mice should be treated.

Antarctic krill serve as a crucial food source for penguins, seals, and whales. They recycle nutrients used by algae. Now researchers say they've found krill in a surprising place: hydrothermal vents.

An extremely well preserved fossil feather could reveal why some birds survived the dinosaur-killing asteroid, and others did not.

Research published in the journal Science illuminates a "missing piece" in the biological understanding of profound autism and offers new targets for drug development.

The Ig Nobel Prizes were awarded this week for humorous yet thought-provoking research. This year, the ceremony came with a twist.

Researchers have identified a speed demon at the heart of the Milky Way. This fast-moving star may yield insights into the black hole parked at the center of our galaxy.

Snails are slimy. But there's more to that goo of theirs than meets the eye. It's a fact that may help inspire the creation of new materials.

Marine biologists off of Baja California recorded one orca teeing up another to smash a sunfish into pieces. Scientists say there could be a reason for this behavior — or it could be just for entertainment.

For more than a decade, there's been something fishy going on in a lake that straddles Vermont and the province of Quebec. It involves cancer, a kind of catfish, and — possibly — clues about how tumors metastasize.

Firefighters working on the nation's largest current wildfire, burning in southern Utah, are being challenged by historic weather conditions. Extreme wildfire behavior is expected to continue through the weekend.
