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 increased toxic protein buildup linked to the ...

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, involving the cancer drivers SRSF1, AURKA, and MYC. By . ...

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, and supported more beneficial bacteria. These ...

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 . ...
