The Science of Living Longer (and Better)

Human lifespan has stalled—but healthspan is entering a surge era. This episode of The Immortality Update explores the geroscience breakthroughs targeting aging at the molecular level: senescence, metabolism, immunity, mitochondria, and epigenetic drift. This week’s discoveries reveal how scientists are shifting from treating diseases one-by-one to modifying the biology that drives them all. In This Episode We Cover: • The “glass floor” in lifespan and why progress stalled • How geroscience targets the root mechanisms of aging • Human evidence of senolytics improving cognition • Immune-senolytic T cells in supercentenarians • The betaine “exercise mimetic” breakthrough • Microbiome engineering for metabolic health • Mitochondrial DNA editing with tail-guided DDCBEs • Biological age reversal (3.23 years in 8 weeks) • AI accelerating drug discovery and patient stratification • Why healthspan—not lifespan—is the real frontier This is the moment aging science shifts from incremental improvements to systemic transformation.
