By growing and modifying immature immune cells rather than mature ones, researchers developed a system that can continuously produce tumor-fighting cells inside the body. Fri, 16 Oct 2026 08:46:50 EDT https://www.sciencedaily.com/releases/2026/10/261015003803.htm https://www.sciencedaily.com/releases/2026/10/261015003550.htm Scientists have uncovered a hidden biological mechanism that helps explain how exercise can reverse some of the damage caused by muscle aging. The key is a gene called DEAF1, which becomes overactive with age and interferes with the muscles’ ability to clear damaged proteins and repair themselves. Exercise can help restore this balance, allowing older muscles to rebuild and regain strength, although the benefits may diminish when the system becomes too disrupted.

Researchers reexamined all eight major randomized screening trials and accounted for differences in follow-up time, screening frequency, and screening after trials ended. Their results were consistent with an overdiagnosis rate below 5%, rather than estimates approaching 30% to 50%.

By blocking tiny blood vessels associated with inflammation, GAE can significantly reduce pain, with some patients reporting little or no pain afterward. Studies suggest the benefits may last two to four years in people who respond well.
