Episode notes
From Novice DJ To Fabric Warm-Up
- Tomasz taught himself to DJ in two weeks and warmed up at Fabric for 2,000 people.
- He later toured and used DJing income to support his PhD studies in longevity.
PhD Muscle Biopsy Breakthrough
- For his PhD, Tomasz and team took muscle biopsies and cultured satellite (muscle stem) cells.
- They showed old cells perform well in young blood and vice versa, implicating environment over intrinsic age.
Environment And Senescence Drive Aging
- Aging is driven by many circulating factors and accumulating inflammation, not only cell-intrinsic damage.
- Senescent (zombie) cells fuel inflammation and are promising therapeutic targets to slow decline.
