Having both excess belly fat and low muscle mass isn't just unhealthy--it's potentially deadly, raising the risk of death by 83%. This condition, called sarcopenic obesity, creates a vicious cycle where fat accelerates muscle breakdown and ...

Researchers have identified a crucial ion channel, TMEM175, that acts like an overflow valve in the cell's recycling system. It regulates acidity inside lysosomes, ensuring they function properly. When TMEM175 is faulty, toxic buildup can occur, ...

By closely monitoring fish throughout their lives, researchers found that simple behaviors in midlife--like movement and sleep--can predict lifespan. Fish that stayed active and slept mostly at night tended to live longer, while those slowing down .. ...

Long COVID remains a frustrating medical mystery, affecting up to 1 in 10 people long after the initial infection fades. Now, scientists have uncovered a crucial clue hidden deep within the immune system. By analyzing individual immune cells, they .. ...

Deepfake X-rays created by AI are now convincing enough to fool both doctors and AI models. In tests, radiologists had limited success identifying fake images, especially when they didn't know they were being shown. This opens the door to risks like ...

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.
