Scientists detect hidden skin damage before it becomes visible
Scientists have discovered a hidden warning sign of skin damage that appears before collagen fibers visibly thin, break, or lose their connections. Using advanced light-based techniques, the team found that collagen’s carefully organized molecular “handedness” can collapse even while the tissue still appears structural

Some dinosaurs could rise like giants until they grew too big
Two elephant-sized South American sauropods were unusually well built for standing on their hind legs.

Alzheimer’s breakthrough: Scientists restore two hours of sleep without clearing brain plaques
Researchers have uncovered a surprising culprit behind sleep loss in Alzheimer’s disease: the brain’s own immune cells. In mice with amyloid plaques, overactive microglia triggered inflammation that kept the brain from getting enough deep, restorative sleep. Temporarily removing most of these cells restored more than t

Scientists discover a protein that protects the brain from Alzheimer’s damage
A protein called SORLA may act as a powerful defense against the toxic tau tangles involved in Alzheimer’s disease. Mice with extra SORLA had less tau accumulation, less brain atrophy, and healthier connections between neurons, while mice without it experienced more severe damage. The findings also revealed a possible
