Scientists uncovered how influenza A commandeers human cells, including a surprising strategy that dissolves tiny structures in the nucleus and releases proteins the virus may use to reproduce. The detailed molecular map could reveal new drug targets ...

A naturally occurring compound found in foods such as wheat germ, mushrooms, and aged cheese may help older adults build stronger protection after vaccination. In a small pilot trial, researchers gave spermidine supplements to adults over 65 ...

Scientists have developed a fully human antibody that halted the growth and spread of aggressive prostate cancer in preclinical research. Although more testing is needed, the drug's unusual mechanism could open the door to a safer new treatment for . ...

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 ...
