Who really needs a heart calcium scan?↗

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 difference by revealing who is actually more likely to

Study of 1.9 million people finds a striking link between ADHD and gut problems↗

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, and more than four times the odds of encopresis.

Scientists find Ozempic may slow aging itself↗

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 drugs could tap into a separate biological pathway li

Eating only 8 hours a day may help control Type 1 diabetes↗

Eating only between noon and 8 p.m. improved blood sugar control in a small study of adults with Type 1 diabetes and obesity, while avoiding an increase in serious complications. The promising findings offer the first evidence that time restricted eating could become another tool for managing the co

Scientists find a way to break pancreatic cancer’s protective shield↗

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 cancer-fighting T cells. That could make chemothera

One sugary drink a day linked to more than double the risk of stomach cancer↗

People who drank at least one sugar-sweetened beverage a day had roughly 2.45 times the risk of gastric cancer compared with those who rarely consumed them, according to a decades-long study of more than 112,000 U.S. adults. Artificially sweetened drinks showed no similar association, though researc
