Scientists have confirmed that Nanotyrannus was a mature species, not a young T. rex. A microscopic look at its hyoid bone provided the key evidence, matching growth signals seen in known T. rex specimens. This discovery suggests a richer, more ...

A remarkably clean gravitational-wave detection has confirmed long-standing predictions about black holes, including Hawking's area theorem and Einstein's ringdown behavior. The findings also provide the strongest support yet that real black holes .. ...

Deep-brain recordings showed that Mounjaro and Zepbound briefly shut down the craving circuits linked to food noise in a patient with severe obesity. Her obsessive thoughts about food disappeared as the medication quieted the nucleus accumbens, the . ...

Researchers revealed that the microbial metabolite TMA can directly block the immune protein IRAK4, reducing inflammation and improving insulin sensitivity. The molecule counteracts damage caused by high-fat diets and even protects mice from sepsis. ...

A large Mayo Clinic study shows that current guidelines fail to detect nearly 90% of people with familial hypercholesterolemia, a common inherited cause of dangerously high cholesterol. Many affected individuals already had early heart disease but .. ...

Scientists found that kale's prized nutrients are hard for the body to absorb unless they're eaten with oil. Cooking doesn't improve absorption, but adding oil-based dressings--or even more advanced nanoemulsion sauces--does. These combinations ...

High-resolution imaging has revealed the internal layout of chromatin condensates, showing how DNA fibers fold and interact within these droplet-like structures. The findings connect molecular architecture to the broader behaviors of these droplets . ...

Researchers have built a fully implantable device that sends light-based messages directly to the brain. Mice learned to interpret these artificial patterns as meaningful signals, even without touch, sight, or sound. The system uses up to 64 micro .. ...

Using less ipilimumab appears to make melanoma immunotherapy both safer and more effective, with dramatically better response and survival outcomes. The findings suggest that reducing side effects may be the key to maximizing the benefits of these .. ...

A newly analyzed set of climate data points to a major volcanic eruption that may have played a key role in the Black Death's arrival. Cooling and crop failures across Europe pushed Italian states to bring in grain from the Black Sea. Those shipments ...
