A major analysis of 139 clinical trials involving nearly 10,000 people suggests that some of the simplest treatments may work best for knee osteoarthritis. Knee braces ranked highest overall for reducing pain, stiffness, and mobility problems, while water-based therapy was especially effective for pain and regular exercise consistently improved both pain and physical function. More high-tech approaches, including ultrasound, generally performed worse.
A newly discovered communication system in the microscopic “antennae” of cells may help explain how some congenital heart defects develop. When genetic mutations disrupt this system, the effects may extend beyond the heart to organs including the brain, kidneys, and skeleton.
Ancient DNA reveals that plague was already killing hunter-gatherers in Siberia 5,500 years ago, long before cities and flea-driven epidemics. The prehistoric strains may have been especially dangerous because they carried a genetic factor capable of provoking severe immune reactions.
