Putin's Secret Plan to Live Forever (And 4 More Longevity Stories This Week)

This week in longevity: the Wall Street Journal reported on a state-backed Russian program targeting lab-grown replacement organs by 2030 — bioprinting, organs grown in animal hosts, and anti-aging gene therapy — though Russian scientists say almost none of it has surfaced in peer-reviewed journals (it also resurfaced that earlier hot-mic moment of Putin and Xi discussing organ replacement and immortality). We also cover a major review on why aging medicine may need to work differently in men and women, Cyclarity's first-in-human safety data on a molecule designed to pull plaque-driving 7-ketocholesterol out of arteries, an AI retinal scan that links eye aging to bone density and fracture risk across 46,000 people, and a blood-based "metabolomic clock" from a 220,000-person UK Biobank analysis that may flag dementia risk years before symptoms. Five real stories, what the data actually shows, and where the hype outruns the evidence. Subscribe for a new longevity roundup every week, and drop your questions below — I read them all.
