Scientists have discovered a tiny group of neurons in an ancient brain region that acts like a built-in focus filter, helping the brain ignore distractions and zero in on what matters most. When researchers temporarily switched off these neurons in . ...

Scientists have uncovered a surprising new twist in what happens when cells die. As dying cells break apart, they leave behind tiny "footprints of death" packed with newly discovered particles that help guide the immune system to clean up the remains ...

A hidden population of South African leopards has revealed a remarkable evolutionary story. Researchers analyzing entire leopard genomes discovered that the Cape Floristic Region's leopards are not only much smaller than most African leopards, but .. ...

A new study suggests early humans were using fire in South Africa's Wonderwerk Cave as far back as 1.79 million years ago. Researchers found burned bones deep inside the cave, where natural wildfires could not have reached, indicating that fire was . ...

A groundbreaking superconducting X-ray spectrometer has begun operation at BESSY II, giving Europe its first TES-based system and boosting photon detection efficiency by up to 1,000 times. The advance enables scientists to explore atomically thin ...

A study of nearly 300 people across northern Britain found that vitamin D levels often stay low all year in groups most at risk. Surprisingly, summer sunshine did not significantly boost vitamin D levels among older adults or people from minoritized ...

Scientists found that one tiny genetic change can completely alter how a coronavirus behaves in different species. Comparing SARS-CoV-2 with a closely related bat-only virus, they showed that a single amino-acid difference affects whether the immune ...

Scientists discovered that kombucha's flavor, chemistry, and antioxidant activity vary dramatically depending on the tea used to make it. Green and oolong tea kombuchas emerged as the most biologically active, while fermentation transformed each tea ...

SETI scientists searched the interstellar object 3I/ATLAS for radio signals that could indicate extraterrestrial technology but found nothing beyond human-made interference. Even so, the rapid-response observations helped confirm the object's natural ...

Researchers uncovered why H5N1 bird flu attacks cows' udders instead of their lungs: the virus's preferred receptors are concentrated in mammary tissue. The breakthrough could help scientists predict future bird flu jumps and spot unusual infections ...
