A large laboratory study found that many commonly used sweeteners can directly change the growth of gut bacteria. Researchers identified more than 100 cases in which sweeteners behaved differently when combined with medications, caffeine, or ...
An ancient sea worm may hold the secret to a whole new category of natural materials. Its jaws combine proteins and metal ions in a way that gives them metal-like strength and unusual mechanical behavior, yet they still differ from traditional metals ...
A distant Sun-like star appears to have devoured one of its planets, leaving behind a surprising chemical fingerprint. Researchers found an unusually high concentration of lithium, a strong sign that planetary material was mixed into the star. ...
An existing constipation drug may have an unexpected new use: helping clear the "brain fog" that often lingers after depression. In a small clinical trial, people with a history of depression who took the medication prucalopride for about a week ...

Researchers found that semaglutide, the active ingredient in Ozempic and Wegovy, slowed biological aging markers in adults with HIV, marking the first clinical evidence that the drug may influence human aging. Although the findings are encouraging, . ...
A fossilized Edmontosaurus skull with a Tyrannosaurus tooth still embedded in its face has given scientists rare evidence of a dramatic predator-prey encounter. The discovery suggests the giant carnivore delivered an incredibly powerful face-to-face ...
A newly discovered network of fine hairs and specialized nerve cells appears to form a dedicated system for sensing mechanical itch, offering fresh insight into why chronic itching occurs. Because humans show signs of having the same pathway, the ...
Physicists from Heinrich Heine University Düsseldorf (HHU) have examined a fundamental property of quantum mechanics in collaboration with the German Aerospace Center (DLR). In the scientific journal Physical Review Letters, they show that this ...
