A new study suggests that dementia may be driven in part by faulty blood flow in the brain. Researchers found that losing a key lipid causes blood vessels to become overactive, disrupting circulation and starving brain tissue. When the missing ...

Scientists are digging into the hidden makeup of carbon-rich asteroids to see whether they could one day fuel space exploration--or even be mined for valuable resources. By analyzing rare meteorites that naturally fall to Earth, researchers have ...

A new eco-friendly technology can capture and destroy PFAS, the dangerous "forever chemicals" found worldwide in water. The material works hundreds to thousands of times faster and more efficiently than current filters, even in river water, tap water ...

Alzheimer's has long been considered irreversible, but new research challenges that assumption. Scientists discovered that severe drops in the brain's energy supply help drive the disease--and restoring that balance can reverse damage, even in ...

What we put on our plates may matter more for the climate than we realize. Researchers found that most people, especially in wealthy countries, are exceeding a "food emissions budget" needed to keep global warming below 2°C. Beef alone accounts for ...

The familiar fight between "mind as software" and "mind as biology" may be a false choice. This work proposes biological computationalism: the idea that brains compute, but not in the abstract, symbol-shuffling way we usually imagine. Instead, ...

AI writing tools are supercharging scientific productivity, with researchers posting up to 50% more papers after adopting them. The biggest beneficiaries are scientists who don't speak English as a first language, potentially shifting global centers ...

The search for life on Earth is speeding up, not slowing down. Scientists are now identifying more than 16,000 new species each year, revealing far more biodiversity than expected across animals, plants, fungi, and beyond. Many species remain ...

A major evolutionary theory says most genetic changes don't really matter, but new evidence suggests that's not true. Researchers found that helpful mutations happen surprisingly often. The twist is that changing environments prevent these mutations ...

Researchers have created a new kind of 3D computer chip that stacks memory and computing elements vertically, dramatically speeding up how data moves inside the chip. Unlike traditional flat designs, this approach avoids the traffic jams that limit . ...
