A team of physicists has discovered a surprisingly simple way to build nuclear clocks using tiny amounts of rare thorium. By electroplating thorium onto steel, they achieved the same results as years ...
Using NASA’s IXPE, astronomers captured an unprecedented view of a white dwarf star actively feeding on material from a companion. The data revealed giant columns of ultra-hot gas shaped by the star’s...
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 doc...
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...
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...
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...
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...
Although the gut renews itself constantly, its stem cells accumulate age-related molecular changes that quietly alter how genes are switched on and off. Scientists found that this “epigenetic drift” f...
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...
Crystals hidden in Australia’s oldest rocks have revealed new clues about how Earth and the Moon formed. The study suggests Earth’s continents didn’t begin growing until hundreds of millions of years ...
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 ...
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...
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...
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...
