“Chemo brain” affects up to 80% of people receiving chemotherapy, making everyday tasks harder. In a new trial, cancer patients who followed a home-based exercise program showed better attention and f...
A study of more than 2,100 adults found that eating more ultra-processed foods was linked to poorer attention and slower mental processing, even among people with otherwise healthy diets. Researchers ...
A surprising gut-heart connection may help explain why sleep apnea increases the risk of cardiovascular disease. In mice, disabling a bile acid receptor called FXR sharply reduced plaque buildup, open...
The mysterious Amaterasu particle may not be a proton at all. New research suggests that some of the most extreme cosmic rays could be ultraheavy atomic nuclei, heavier than iron, which are better abl...
Tea may help protect against heart disease, diabetes, cancer, cognitive decline, and age related muscle loss, according to a major review. But the way you drink it matters, since bottled and bubble te...
