Longevity & AgingRandom Cellular Noise May Drive Aging More Than Genetics Ever Could
Aging may not be a programmed countdown but rather the slow accumulation of random cellular errors over time. Dr. David Meyer, an aging researcher at the University of Cologne, breaks down how popular aging clocks — tools that estimate biological age using DNA methylation patterns — are actually tracking this buildup of cellular noise rather than a fixed genetic program. He explores the DREAM complex, a master regulator of DNA repair, and explains why its decline accelerates aging. The conversation covers how interventions like caloric restriction and rapamycin may slow this noisy accumulation, and how cellular reprogramming techniques show promise for resetting biological age. This reframes aging as something potentially reversible, not inevitable.
