Understanding Sarcopenia and Combatting Age-Related Muscle Wasting

To kick off 2024, we’re bringing you an episode that’s been one of our most popular. The timing is just right as many of us are headed into the new year thinking about how to live better. In this episode, Professor Helen Blau, a stem cell biologist, tells us all about how she’s recruiting stem cells to regenerate youthful muscle in older people. We’re thrilled to bring this episode out of the archives for another listen and renewed hope about possibilities ahead in the world of health.  Happy New Year from Russ and the team here at The Future of Everything.
