Sleep isn’t just about feeling rested—it may be one of the strongest predictors of how long you live. Researchers analyzing nationwide data found that insufficient sleep was more closely tied to short...
New research shows that aging blood can accelerate Alzheimer’s-like changes in the brain, while younger blood may offer protection. In mouse experiments, older blood worsened memory performance and in...
Pancreatic cancer is notoriously hard to treat, often resisting therapies that target its most common mutations. Researchers have now uncovered a hidden three-part loop that fuels tumor growth, involv...
Astronomers have uncovered the long-hidden cause behind Betelgeuse’s strange behavior: a small companion star carving a visible wake through the giant’s vast atmosphere. Using nearly eight years of ob...
Hubble has revealed a strange cosmic object called Cloud-9, a dark matter–dominated cloud with no stars at all. Scientists believe it is a “failed galaxy,” a leftover building block from the early Uni...
Sugar-loving mouth bacteria create acids that damage teeth, but arginine can help fight back. In a clinical trial, arginine-treated dental plaque stayed less acidic, became structurally less harmful, ...
Scientists at USC are launching a new trial to test a tiny stem cell implant that could restore vision in people with advanced dry macular degeneration. The hair-thin patch replaces damaged retinal ce...
A large genetic study shows that many people carry DNA sequences that slowly expand as they get older. Common genetic variants can dramatically alter how fast this expansion happens, sometimes multipl...
Foods that rely heavily on preservatives may be doing more than extending shelf life. In a large study spanning more than a decade, people with the highest intake of preservative additives were far mo...
Researchers have developed a new class of antibodies that amplify the immune system’s ability to fight cancer. By clustering immune receptors that normally receive weak signals from tumors, these four...
Scientists in South Korea have discovered a way to make all-solid-state batteries safer and more powerful using inexpensive materials. Instead of adding costly metals, they redesigned the battery’s in...
Stanford researchers have developed an AI that can predict future disease risk using data from just one night of sleep. The system analyzes detailed physiological signals, looking for hidden patterns ...
