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. ...

Aging men often lose the Y chromosome in a growing number of their cells--and it may be far more dangerous than once believed. This loss has been linked to heart disease, cancer, Alzheimer's, and shorter lifespans. Researchers suspect Y-less cells .. ...

The largest review of medicinal cannabis to date found it doesn't effectively treat anxiety, depression, or PTSD--despite millions using it for those reasons. Researchers warn it could even make mental health worse, raising risks like psychosis and . ...

A shingles vaccine might double as a powerful heart protector. In people already at high risk, it cut major cardiac events by 46% and deaths by an impressive 66% within a year. Scientists think preventing shingles may also stop clot-related ...
