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 ...

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 . ...

Dogs may understand our emotions more deeply than scientists realized. Brain scans show that happy human faces activate regions in dogs linked to higher-level processing and reward, suggesting that smiles carry special emotional significance for them ...

MIT neuroscientists have found striking evidence that language and logical reasoning are powered by separate systems in the brain. Even people with severe language impairments caused by stroke were able to solve challenging logic puzzles as well as . ...

Scientists have created an unusually corrosion-resistant stainless steel that could replace costly titanium components used to produce green hydrogen. The breakthrough could reduce structural material costs by roughly 40 times and make seawater-based ...

Marine heatwaves are emerging as a threat not just to coral reefs and fisheries, but to human health and well-being. Researchers warn that unusually hot oceans can fuel stronger storms, trigger harmful algal blooms, reduce seafood supplies, disrupt . ...
