AI has helped scientists measure the brain's hidden cleaning system, revealing that fluid moves rapidly around its outer spaces but about 50 times more slowly through deep tissue. The discovery could eventually help researchers detect circulation ...

Ozempic-like drugs appear to weaken more than hunger--they may also reduce cravings for alcohol and other addictive substances. Scientists are increasingly tracing this effect to the lateral septum, a brain region that helps connect memories and ...

Researchers have found a clever new way to map a part of Earth's upper atmosphere that is notoriously difficult to observe. Using orbital data from roughly 1,200 Starlink satellites, they reconstructed changes in atmospheric density about 500 ...

Scientists have pinpointed a brain network--and its distinctive electrical rhythm--that appears to drive the benefits of deep brain stimulation for Parkinson's disease. The discovery could lead to more precise, personalized stimulation settings and . ...

Ancient remains from Vietnam suggest diseases like yaws may have been passed from mother to child thousands of years ago, a form of transmission often assumed to indicate syphilis. The discovery could overturn how scientists interpret ancient ...

The adult brain may be far better at repairing itself than scientists once believed. In mice, researchers discovered a special group of support cells called astrocytes that respond to damaged brain tissue by rebuilding lost cellular networks. Rather ...

Keratin extracted from sheep's wool helped damaged bone regenerate in animals, producing tissue that was more organized and structurally similar to healthy bone than tissue grown with conventional collagen scaffolds. The discovery could turn an ...

James Webb has captured a striking new infrared view of NGC 2392, the Lion Nebula, revealing the dramatic aftermath of a dying Sun-like star. At its center, a scorching white dwarf is blasting radiation into surrounding gas and dust, carving out the ...

Physicists have found a new way to peer inside one of matter's most elusive quantum states: the Wigner crystal, where electrons stop behaving like independent particles and organize into a crystal-like pattern. By shining light on an atomically thin ...

Scientists probing life's deepest origins have uncovered evidence that the first free-living cells may have emerged not once, but twice. The findings suggest a striking possibility: life may share one ancient genetic code, yet have undergone two ...
