Researchers uncovered a 2.75-2.44 million-year-old site in Kenya showing that early humans maintained stone tool traditions for nearly 300,000 years despite extreme climate swings. The tools, remarkably consistent across generations, helped our ...

A new compound called CMX410 may change the fight against tuberculosis. It targets a weak point in the bacteria's defenses, even in drug-resistant forms of the disease. Created using a cutting-edge chemistry method, the drug shows promise for being . ...

Walking a few thousand steps daily may help hold off Alzheimer's for years, a Mass General Brigham study found. Even moderate physical activity slowed both cognitive decline and the buildup of harmful tau proteins in the brain. The researchers say .. ...

Beneath the ocean's surface, bacteria have evolved specialized enzymes that can digest PET plastic, the material used in bottles and clothes. Researchers at KAUST discovered that a unique molecular signature distinguishes enzymes capable of ...

Scientists at TU Wien found that electrons need specific "doorway states" to escape solids, not just energy. The insight explains long-standing anomalies in experiments and unlocks new ways to engineer layered materials.

A collaboration between Brazilian and German researchers has led to a sunflower-based meat substitute that's high in protein and minerals. The new ingredient, made from refined sunflower flour, delivers excellent nutritional value and a mild flavor. ...

Researchers at MIT's Picower Institute found that rotating waves of brain activity help restore focus after distractions. In animal tests, these rotations predicted performance: full rotations meant full recovery, while incomplete ones led to errors. ...

Researchers have discovered a specific set of neurons in the amygdala that can trigger anxiety and social deficits when overactive. By restoring the excitability balance in this brain region, they successfully reversed these symptoms in mice. The ...

Using powerful 7-Tesla brain imaging, researchers mapped how the brainstem manages pain differently across the body. They discovered that distinct regions activate for facial versus limb pain, showing the brain's built-in precision pain control ...

Long-term melatonin use for sleep problems may come with unexpected heart dangers. Researchers found that chronic users were almost twice as likely to die and 3.5 times more likely to be hospitalized for heart failure. Though melatonin is widely ...
