Scientists have uncovered how your body actually tells your brain to stop eating when you're sick. In a new study, researchers found that specialized cells in the gut detect parasites and send signals that ultimately trigger the brain to suppress ...

Scientists have identified a key biological system that helps brown fat burn energy by building the networks it needs to function. A protein called SLIT3 splits into two parts, with each piece guiding the growth of blood vessels and nerves inside ...

A new study reveals that high doses of antioxidants--often seen as harmless or beneficial--may actually impact future generations. Male mice given common supplements like NAC produced offspring with subtle but significant facial and skull changes. .. ...

Scientists have uncovered a hidden reason why cancer treatments don't work equally well for everyone. Certain drugs can become trapped inside lysosomes within tumor cells, forming slow-release reservoirs that create uneven drug distribution. This ...

Gut bacteria aren't just passive passengers--they can actively send proteins straight into our cells. Using microscopic injection systems, even harmless microbes can influence immune responses and metabolic pathways. Researchers found these ...

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 ...
