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 dissolve...

A daily glass of 100% fruit juice or a smoothie may help improve more than just fruit intake. In a small four-week trial, participants who added one to a healthier diet showed significantly lower depression scores, hinti...

Just a couple of hours of strength training each week could have surprisingly powerful effects on longevity. People who lifted weights for around 90 to 120 minutes weekly had a 13% lower risk of dying early, with especia...

From schools of fish and flocks of birds to microscopic synthetic particles, many systems in nature and the laboratory consist of individual units or agents that move by consuming energy. These systems are known as activ...

Science writer Kit Chapman on the weird world of alchemy before chemistry.

A new James Webb telescope study suggests the universe's enigmatic "little red dots" may not have vanished after all - they may simply look different as we observe them across cosmic time.

"Uncontacted" and "isolated" peoples live in roughly 10 countries around the world, including one group that erases their footprints so they cannot easily be found.

Frequent cannabis users may wake up with unusually high levels of the stress hormone cortisol, suggesting their daily stress rhythms could be disrupted. Researchers say the finding raises questions about whether using ca...

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...

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 reactio...

Dinosaurs conquered the land at enormous sizes, but strangely, they almost never evolved into truly tiny animals. New research suggests that physiology alone cant explain this missing miniature end of the dinosaur spectr...

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, an...

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 atom...
