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 . ...

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, ...

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 ...

Scientists have redesigned zinc oxide particles to create a mineral sunscreen that protects against ultraviolet radiation without leaving such a noticeable white cast. The SPF 30 formula could make sunscreen easier and more appealing to use across a ...

The mysterious sound known as The Hum has been reported worldwide for decades, yet its source often remains impossible to find. Researchers tested whether people who hear it have exceptional low-frequency hearing or measurable sounds produced inside ...

Scientists may have uncovered one reason coffee is repeatedly associated with healthier aging and lower disease risk. Compounds in coffee appear to activate NR4A1, a receptor that helps protect cells from stress, inflammation, and damage. These ...

A low-cost antidepressant may offer new hope for people struggling with long COVID fatigue. In a randomized clinical trial involving 399 adults, fluvoxamine significantly reduced fatigue and improved quality of life compared with a placebo, making it ...

Several popular sugar substitutes may not be as harmless as they seem. Adults who consumed the most artificial sweeteners showed substantially faster declines in memory and thinking, especially if they were under 60 or had diabetes. The highest ...

A 12-week intermittent fasting program produced weight-loss benefits that were still visible a year later. Participants who ate within an eight-hour window maintained more weight loss than those who followed their usual longer eating schedule. Both . ...

The Mediterranean diet may influence aging through tiny proteins produced inside the cell's mitochondria. Older adults who followed the diet most closely had higher levels of humanin and SHMOOSE, which have been linked to heart and brain protection. ...
