Deep inside a cave, scientists uncovered fossils from 16 species, including a newfound kkp ancestor that may have been able to fly. These remains reveal that New Zealand's ecosystems were constantly disrupted by volcanic eruptions and rapid climate . ...

A new prototype could supercharge mass spectrometry by analyzing thousands of molecules at once instead of one by one. The breakthrough boosts sensitivity enough to reveal rare, hidden molecules--potentially transforming fields like drug discovery .. ...

When temperatures plunge, the risk to your heart rises dramatically. A large U.S. study shows cold weather is linked to far more cardiovascular deaths than heat, accounting for tens of thousands of extra deaths each year. Scientists found the safest ...

Scientists have discovered that losing a key protein in small cell lung cancer triggers inflammation that actually helps tumors grow and spread. Even more surprising, it pushes cancer cells into a more aggressive, neuron-like state linked to relapse.

In a remarkable deep-sea breakthrough, researchers have discovered 24 new species of amphipods in the Pacific's Clarion-Clipperton Zone--including a rare, entirely new superfamily. The findings reveal previously unknown branches of life and push the ...

Flower nectar often contains small amounts of alcohol, meaning pollinators like hummingbirds are drinking it all day long. Despite consuming human-equivalent amounts, they show no signs of intoxication--suggesting a surprising evolutionary tolerance.

A major discovery reveals that metformin works not just in the body, but in the brain. By switching off a key protein and activating specific neurons, the drug lowers blood sugar through a previously hidden pathway, opening new doors for diabetes ...

A star you can see with the naked eye has kept astronomers guessing for decades with its unusually powerful X-rays. Now, thanks to highly precise observations from Japan's XRISM space telescope, scientists have finally uncovered the source: a hidden ...

Astronomers have narrowed down the cosmic search for life, identifying fewer than 50 rocky planets among thousands of known exoplanets that may have the right conditions to support life. Using new data from ESA's Gaia mission and NASA archives, ...

Nearly half of Americans don't know that processed meat increases colorectal cancer risk, according to a new poll. But once they learn the connection, most support warning labels--suggesting people want clearer information. Experts warn that ...
