INFORMAZIONI SU QUESTO EPISODIO
In this episode of Longevity Roundtable for September 2026, I’m joined by Brian Kennedy and Marcus Ranney to dig into some of the biggest recent stories in longevity science and medicine.We start with Marcus fresh off a high-altitude marathon and discuss intermittent hypoxia, hyperoxia, and hyperbaric oxygen therapy. From there, we take a close look at the new mouse lifespan data on semaglutide and what it does, and doesn’t, tell us about GLP-1 drugs and biological aging. We also discuss concerns about GLP-1s and vision loss, and how to think about potential risks in the context of their demonstrated benefits.Then we turn to new evidence linking statin use with reduced dementia risk, the persistent concern that lowering cholesterol could negatively affect the brain, and what the evidence actually suggests.We also tackle a recent Nature Medicine study asking whether epigenetic aging clocks respond to longevity interventions. Can these clocks really tell us whether an intervention is slowing biological aging? And what should we make of the fact that interventions like exercise and rapamycin don't necessarily move them in the direction we might expect?Finally, we discuss Montana’s new Right to Try framework for experimental therapies, why I agreed to serve on its review board, and whether new regulatory models could generate useful clinical data while giving patients greater access to experimental treatments. And, naturally, we finish with Bryan Johnson—because apparently no Longevity Roundtable is complete without him.Topics include: GLP-1 agonists and lifespan, semaglutide, intermittent hypoxia, hyperbaric oxygen, statins and dementia, cholesterol and brain health, epigenetic aging clocks, rapamycin, Right to Try, experimental medicine, and the future of longevity science.DISCLAIMER: The information provided on this channel is intended solely for general educational purposes and is not meant to be, nor should it be construed as, personalized medical advice.
