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 ...

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 .. ...

Many people believe closing their eyes sharpens hearing, but that is not always true. In noisy settings, participants struggled more to hear faint sounds with their eyes closed, while matching visuals made it easier. Researchers found that shutting . ...

A mysterious spike of platinum buried deep in Greenland's ice has long fueled theories of a catastrophic comet or asteroid strike 12,800 years ago--possibly triggering a sudden return to icy conditions known as the Younger Dryas. But new research ...

A nearby galaxy is behaving strangely--and now scientists know why. The Small Magellanic Cloud's stars move in chaotic patterns because it slammed into its larger neighbor millions of years ago. That collision disrupted its structure and even created ...

Researchers have created a cutting-edge catalyst that turns CO2 into methanol more efficiently than ever before. Instead of using clumps of metal atoms, they engineered a system where each single indium atom actively drives the reaction. This ...

Stopping popular weight-loss injections like Ozempic or Mounjaro might not trigger the dramatic rebound many fear. A large real-world study of nearly 8,000 patients found that most people who discontinue these drugs manage to keep the weight off--or ...

Ravens have long been thought to follow wolves to find food, but new research shows they're far more strategic. By tracking both animals in Yellowstone, scientists discovered that ravens memorize areas where wolf kills are likely and fly directly to ...

New strength training guidelines emphasize that doing any resistance training is what truly matters. Based on decades of research, experts say even simple routines can increase muscle, strength, and physical function. The key is not perfection but .. ...
