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 cells responsible for sharp, central vision. Earlier ...

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 multiplying the pace by four. Researchers also identified ...

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 more likely to develop type 2 diabetes. The ...

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-pronged antibodies push T cells into full attack ...

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 across the brain, heart, and breathing. It ...

A new study finds that TikTok videos about gout frequently spread confusing or inaccurate advice. Most clips focus on diet changes and supplements, while barely mentioning the long-term treatments doctors say are essential for controlling the disease ...

DNA doesn't just sit still inside our cells -- it folds, loops, and rearranges in ways that shape how genes behave. Researchers have now mapped this hidden architecture in unprecedented detail, showing how genome structure changes from cell to cell . ...

Long COVID affects an estimated 65 million people worldwide and can damage the brain, heart, blood vessels, and immune system long after infection. Researchers now link symptoms to lingering virus, inflammation, micro-clots, and disrupted energy ...

Scientists are uncovering why Brazil may be one of the most important yet underused resources for studying extreme longevity. Its highly diverse population harbors millions of genetic variants missing from standard datasets, including rare changes .. ...

A brief, intense workout may do more than boost fitness--it could help fight cancer. Researchers found that just 10 minutes of hard exercise releases molecules into the bloodstream that switch on DNA repair and shut down cancer growth signals. When . ...
