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 ...

Dying Sun-like stars may not fade away quietly. As blobs of gas erupt unevenly from their swollen surfaces, each burst gives the star a tiny push in the opposite direction. Thousands of these random kicks could eventually break apart distant stellar ...

A new theoretical study offers a possible explanation for how the Universe can grow more complex without violating the second law of thermodynamics. Using a quantum gravity framework called Gravity from Entropy, mathematician Ginestra Bianconi found ...

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 . ...

Two elephant-sized South American sauropods were unusually well built for standing on their hind legs. Digital tests showed that their robust femurs handled the enormous forces better than those of larger species, especially while the dinosaurs were ...

Oxygen is disappearing from oceans, lakes, rivers, and coastal waters at an alarming rate, threatening aquatic life and weakening the natural processes that help regulate Earth's climate. Scientists warn that this widespread deoxygenation is closely ...

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 quantum problem once described as impossible for classical computers has now been solved using relatively modest hardware. Researchers used tensor networks to compress the overwhelming wave function created by hundreds of entangled qubits, allowing ...

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 ...
