A cow named Veronika has stunned scientists by using tools in a flexible and purposeful way. She chooses different ends of a brush depending on the part of her body and adjusts her movements accordingly. This level of tool use is incredibly rare 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 ...

Snow flies have an unexpected way of surviving freezing temperatures. They produce antifreeze proteins to block ice formation and can even generate their own heat. Scientists also found that their genes are unusually unique, and they feel less cold . ...

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 ...
