Endocrinologist <a href="https://profiles.stanford.edu/joy-wu">Joy Wu</a> says that osteoporosis can affect more than half of women and a quarter of men over 50 – often without symptoms until a fracture changes everything, leading to a loss of mobility and independence. Wu explains why bones weaken with age and how to strengthen them through exercise and smart medicine. Her lab is exploring innovative drugs and turning skin cells into new bone-forming osteoblasts. We’re delving into the great mystery of building new bone and making old bones stronger, Wu tells host <a href="https://profiles.stanford.edu/russ-altman">Russ Altman</a> on this episode of Stanford Engineering’s The Future of Everything podcast.Have a question for Russ?
