Kira Labs episode topics: aging, exercise and senescent cells
The description says the episode looks at healthy aging, exercise and mobility, the hallmarks of aging, senescent cells described as “zombie” cells, senolytics, PCC1, partial epigenetic reprogramming, biological-age clocks and early human research. McMurrer frames the central question as more than whether a treatment changes a laboratory measurement: what does it mean for someone’s health, independence and years of life? The description lists a physical-activity trial and a paper on the hallmarks of aging among its sources.
