Scientists have found a surprising way to regrow damaged knee cartilage by blocking a protein that becomes more abundant with age. In old mice, the treatment restored naturally lost cartilage and also helped prevent osteoarthritis after ACL-like knee injuries, while human cartila
Scientists have found a surprising way to regrow damaged knee cartilage by blocking a protein that becomes more abundant with age. In old mice, the treatment restored naturally lost cartilage and also helped prevent osteoarthritis after ACL-like knee injuries, while human cartilage taken from knee replacement patients began producing new, functional joint cartilage after exposure to the same inhibitor.

Scientists may have found a “unifying theory” of chronic fatigue
Scientists found that five seemingly unrelated conditions, including long Covid, ME/CFS, and PTSD, may disrupt many of the same biological networks involved in immunity, metabolism, and cellular energy. The findings could help explain their shared symptoms and may open the door t
