A large study involving more than 270,000 people has linked higher blood levels of the amino acid tyrosine to a shorter lifespan in men. Using both observational data and genetic analysis, researchers found that elevated tyrosine could potentially .. ...

Researchers have mapped breast tumors in striking detail and uncovered hidden pockets of dormant cancer cells that may help explain why cancer can return after treatment. Unlike rapidly dividing cells, these quiet cells can essentially hibernate, ...

Older adults at risk of dementia improved their memory and thinking after following lifestyle programs combining exercise, healthy eating, cognitive training, and social engagement. Those who received regular coaching and structured support improved ...

Sorbitol, a sugar alcohol commonly used in sugar-free candy, gum, and other low-calorie foods, may not be as harmless as it seems. Researchers at Washington University in St. Louis found that the body can convert sorbitol into a form of fructose in . ...

Indonesia's dangerous peat fires are surging early in the 2026 fire season as a strengthening El Niño and severe drought dry out wetlands that can burn underground for months. These slow smoldering fires are especially destructive because they ...

Princeton researchers have tested an AI system that can monitor and control fusion plasma in milliseconds, reacting far faster than a human operator. In one experiment, it predicted a damaging instability about 200 milliseconds before it appeared and ...

Researchers may have found a new way to weaken glioblastoma's defenses against treatment. Blocking a protein called SET prevented tumors from forming in preclinical models, while targeting related proteins made cancer cells more vulnerable to ...

Scientists used Earth's magnetic field and atmosphere as a planet-sized detector to search for some of the lightest proposed forms of dark matter. The approach dramatically improved limits on ultralight axions and uncovered several intriguing dark .. ...

Archaeologists have identified tiny 80,000-year-old projectile points in Uzbekistan that may have been used like arrowheads. Their size, design, and impact damage closely resemble weapons found much later at a Homo sapiens site in France. The ...

Heart disease and chronic kidney disease can accelerate one another, but new guidelines say simple screening and early treatment could substantially reduce the risks. Blood and urine tests, combined with proven heart and kidney therapies, may help .. ...
