Vivid dreams might be doing more than just entertaining your mind at night. Researchers found that immersive dreaming can actually make sleep feel deeper and more refreshing, even when brain activity is high. Surprisingly, people reported their ...

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.

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 ...

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 ...

Balance problems in aging and Parkinson's may come from the body working too hard, not too little. Scientists found that the brain and muscles become overactive during even minor disturbances, yet this actually weakens balance recovery. At the same . ...

Researchers have visualized atoms in motion just before a radiation-driven decay process occurs, revealing a surprisingly dynamic scene. Instead of remaining fixed, the atoms roam and rearrange, directly influencing how and when the decay unfolds. .. ...

New fathers appear to have fewer mental health diagnoses during pregnancy and the early months after birth. But that early stability does not last. About a year later, depression and stress-related disorders increase significantly, surprising ...
