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, ...
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, ...
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 ...
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 ...
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 ...
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 ...
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 ...
