MIT engineers have developed injectable "mini livers" designed to help support people whose failing livers can no longer perform essential jobs. Instead of replacing the damaged organ, the approach injects liver cells together with tiny hydrogel ...

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 . ...

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 ...

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 .. ...

Scientists have found evidence that vulnerability to rheumatoid arthritis may begin before birth. Finger joints commonly affected by the disease develop with different tissue structures and larger populations of specialized fibroblasts than joints .. ...

Scientists in Japan have identified a natural compound found in blueberries, grapes, and other berries that may help muscle cells burn excess fat instead of storing it. The compound, pterostilbene, reduced abnormal fat buildup in cultured mouse ...

A substance found in edible sea squirts appeared to reverse several signs of aging in older mice. Plasmalogen supplements improved memory and learning, strengthened connections between brain cells, reduced inflammation, and even helped the mice grow ...
