Researchers have uncovered friction without contact--driven entirely by magnetic interactions. As two magnetic layers slide, their internal forces compete, causing constant rearrangements that dramatically increase resistance at certain distances. .. ...

Astronomers have uncovered surprising evidence of a thick atmosphere surrounding TOI-561 b, a scorching, fast-orbiting rocky planet once thought too extreme to hold onto any gas. Using NASA's James Webb Space Telescope, researchers found the planet . ...

A new study reveals that farming in Argentina's Uspallata Valley was adopted by local hunter-gatherers rather than introduced by outside populations. Centuries later, a stressed group of maize-heavy farmers migrated into the region, facing climate .. ...

A hidden freshwater system deep beneath the Great Salt Lake has been revealed using airborne electromagnetic surveys. Scientists found that freshwater extends much farther under the lake than expected, reaching depths of up to 4 kilometers. The ...

Antibiotics are accumulating in a major Brazilian river, especially during the dry season when pollution becomes more concentrated. Scientists even detected a banned drug inside fish sold for food, raising concerns about human exposure. A common ...

A new pill, enlicitide, reduced LDL ("bad") cholesterol by about 60% in a large clinical trial, matching the power of injectable therapies. Because it's taken orally, it could overcome one of the biggest barriers keeping patients from using current . ...

Researchers have discovered that cancer spread isn't random--it follows a kind of biological "program." By studying colon tumor cells, they identified gene patterns that signal whether a cancer is likely to metastasize. Their AI model, MangroveGS, .. ...

Scientists at Harvard have built a miniature device that can twist and tune light in real time. By rotating two stacked photonic crystals and adjusting their spacing with a tiny mechanical system, they can control how light's "handedness" behaves. .. ...

A routine quantum optics technique just revealed an extraordinary secret: entangled light can carry incredibly complex topological structures. Researchers found these hidden patterns reach up to 48 dimensions, offering a vast new "alphabet" for ...

A newly discovered Triassic reptile from the UK looked more like a racing greyhound than a crocodile, built for speed on land. With long legs and a lightweight body, it hunted small animals in a dry, upland environment millions of years ago. ...
