5 Longevity Breakthroughs That Just Happened This Week!

This week in longevity: a UC Berkeley paper in Aging-US shows a two-drug combo of oxytocin and an ALK5 inhibitor extended lifespan in old male mice by around 70% — but female mice only got short-term gains, raising big questions about sex-specific aging therapies. Plus: why naked mole-rats keep youthful skin at 40 years old (it's how their hyaluronic acid is organized, not how much they have), how Greenland sharks live 300 years with hearts that look damaged on every level (resilience to damage, not avoidance of it), a new npj Aging study from Hainan showing lifestyle outweighs longevity genes three to one in people over 90, and Abu Dhabi inviting the entire longevity industry to test technologies across its national health network — the first country-scale geroscience experiment.
