Full-fat dairy may be healthier than conventional advice has suggested. In a 12-week study, adults who ate three servings a day showed no meaningful increases in weight, body fat, cholesterol, or insulin resistance. They also experienced improved ...

More than 60,000 years ago, humans in southern Africa were engraving ostrich eggshells with intricate geometric patterns that appear far more organized than previously realized. Researchers found recurring grids, parallel lines, right angles, and ...

Deep underground, bacteria may be capable of doing something remarkable: trapping toxic uranium before it spreads. When researchers fed microbes in uranium-contaminated mine water with glycerol, about 95% of the dissolved uranium disappeared within . ...

Chemists have developed a catalyst that breaks a long-standing rule governing which molecules receive electrons during chemical reactions. By releasing electrons directly into solution, the technique could unlock reactions--and potentially useful new ...

Dinosaurs conquered the land at enormous sizes, but strangely, they almost never evolved into truly tiny animals. New research suggests that physiology alone can't explain this missing miniature end of the dinosaur spectrum--and that early mammals .. ...

A study tracking more than 340,000 adults for over a decade found that heavy drinking increased the risk of death regardless of beverage type. At lower levels, however, the picture became more surprising: beer, cider, and spirits were linked to ...

Atomically thin semiconductors could enable dramatically smaller and more efficient chips, but a stubborn problem at the boundary between materials has limited their performance. Researchers have now engineered that atomic interface to protect ...

An intensive seven-day meditation retreat triggered striking changes across the brain and body, including shifts tied to neuroplasticity, immunity, metabolism, and natural pain relief. Participants also showed brain connectivity patterns resembling . ...

Stress may literally scramble the brain's internal GPS. Researchers found that cortisol, a hormone released during stress, made people significantly worse at navigating a virtual environment and disrupted the precise activity of grid cells, ...

CT scans of the world's rarest dodo skulls suggest the extinct bird may have had a stronger sense of smell, a highly sensitive beak, and a lifestyle that extended into dawn and dusk. The discoveries are helping overturn centuries-old myths and reveal ...
