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. ...

Scientists have uncovered the oldest direct evidence yet that Earth's tectonic plates were on the move 3.5 billion years ago. By analyzing magnetic fingerprints in ancient rocks, they reconstructed how parts of the planet slowly drifted and even ...

In an incredibly lucky cosmic accident, NASA's Hubble Space Telescope captured a comet breaking apart in real time--something astronomers have long tried and failed to observe. The comet, C/2025 K1 (ATLAS), wasn't even the original target, but when . ...

Scientists have engineered probiotic bacteria to act as tumor-seeking drug factories. In mice, these bacteria infiltrated tumors and produced a cancer-fighting drug right where it was needed. This targeted approach could make treatments more ...

"Forever chemicals" may be affecting kids in ways that last a lifetime. A new study links early PFAS exposure to lower bone density during the teen years, especially in girls. Researchers also found that when exposure happens may play a key role. ...
