Osteopenia is a common but often overlooked condition that causes bones to become less dense and more fragile. Because it develops silently, many people only discover they have it after a fracture or bone scan. Aging, menopause, poor diet, and ...

A Pacific-wide tsunami triggered by a magnitude 8.8 Kamchatka earthquake gave scientists their first detailed satellite view of a major tsunami in motion. The observations revealed unexpected wave behavior and helped uncover a larger earthquake ...

What if consciousness isn't limited to brains like ours? Philosophers Eric Schwitzgebel and Jeremy Pober argue that consciousness could arise in many different forms of life, even in beings built from radically different materials than those found on ...

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 ...
