Scientists have uncovered a natural braking system that helps the immune system switch off inflammation and prevent harmful immune cells from building up. Boosting this pathway in people reduced inflammation-related immune changes and sped up pain .. ...

A 10-year study of more than 6,000 adults found that popular coronary calcium scans may add little to standard heart disease risk estimates for many people. But for patients with borderline or intermediate risk, the scans could make a meaningful ...

Semaglutide helped older healthy mice live longer while improving memory, muscle function, blood sugar control, and several biological signs of aging. Its effects went beyond those seen with calorie restriction, raising the possibility that GLP-1 ...

Researchers found that blocking IL1RAP could disrupt a powerful inflammatory network that helps pancreatic cancer survive treatment. In preclinical experiments, the approach reduced tumor-protecting cells and fibrosis while boosting the activity of . ...

Long-lived bats appear to combine powerful immune defenses with unusual strategies for eliminating damaged cells, potentially helping them avoid cancer and disease for decades. Researchers hope these genetic tricks could eventually reveal new ways to ...

Nighttime light exposure was linked to thicker, stiffer heart chambers and early signs of reduced heart function in a study of more than 11,000 people. The findings suggest that keeping bedrooms darker could be an overlooked strategy for protecting . ...

A major Ontario study found 24 common medication chains in which one drug's side effects can be mistaken for a new medical problem, leading to another prescription. Researchers say closer medication reviews, pharmacist involvement, and automated ...

Researchers analyzing data from more than 1.9 million people found that ADHD is associated with substantially higher rates of digestive problems. People with ADHD had nearly double the odds of constipation, 58% higher odds of irritable bowel syndrome ...

A remarkably detailed study of Maria Branyas, who lived past 117, reveals that extreme longevity may involve both intense aging and powerful biological protection at the same time. Researchers found signs of advanced aging, but also low inflammation, ...

Researchers have shown for the first time that human heart muscle cells can regrow after a heart attack. The finding overturns the idea that damaged areas of the heart are completely incapable of regeneration. Scientists now hope to identify ways to ...
