Ancient DNA Study Rewrites Origins of Europe’s First Dogs

Scientists have extracted and analyzed DNA from 216 canid remains, including 181 from Paleolithic and Mesolithic Europe. The oldest data that they recovered are from a 14,200-year-old dog from the Kesslerloch site in Switzerland. Their results suggest that domesticated dogs (Canis lupus familiaris) predate farming and share deep ancestry with wolves (Canis lupus) from Eurasia, challenging ideas about...

In the cold, wave-battered channels off southern Chile, scientists have identified what they say is a new species of the steamer duck genus Tachyeres, a group of notoriously aggressive, often flightless waterfowl found only in South America.

Physicists Create Levitating Form of Time Crystal

Morrell et al. observed a new type of time crystal -- one whose particles levitate on a cushion of sound while interacting with each other by exchanging sound waves. Image credit: David Song / NYU.

A team of scientists at New York University has created a version of the exotic phase of matter in which particles levitate acoustically and interact by exchanging sound waves. Morrell et al. observed a new type of time crystal — one whose particles levitate on a cushion of sound while interacting with each other by exchanging sound waves. Image credit: David Song / NYU. Time crystals —...

Vitamin D Shows Promise in Resetting Immune System in Inflammatory Bowel Disease

Gubatan et al. demonstrate that vitamin D promotes immune tolerance to gut microbiota in patients with inflammatory bowel disease. Image credit: Gubatan et al., doi: 10.1016/j.xcrm.2026.102703.

New research suggests that vitamin D supplements can reshape how the immune system responds to gut bacteria in patients with inflammatory bowel disease, potentially nudging the body toward a more protective, less inflammatory state. The findings offer early clues toward therapies that restore immune tolerance rather than simply suppress symptoms. Gubatan et al. demonstrate that vitamin D promotes...
