Ozempic may have revealed the brain’s hidden “craving center”
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 surroun…
Scientists turn Starlink into a giant scanner for Earth’s upper atmosphere
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 kilometer…
Scientists discover a hidden brain rhythm that could improve Parkinson’s treatment
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 bette…
3,500-year-old skeletons challenge what scientists thought they knew about syphilis
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 infection…
The adult brain can repair itself better than scientists thought
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 th…
Scientists turn sheep’s wool into a material that helps regrow bone
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 abundan…
James Webb captures a cosmic lion sculpted by a dying star
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 ne…
A strange crystal made of electrons just revealed its hidden motion
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 ma…
Scientists find evidence for two origins of life on Earth
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 separa…
Ordinary WiFi can now identify you with near-perfect accuracy
Ordinary WiFi networks could quietly become powerful surveillance tools, allowing people to be identified without cameras, special sensors, or even carrying a connected device. Researchers showed that unencrypted signals routinely exchanged between WiF…
