28% of body weight is the headline number today, and it came with improved blood sugar, blood pressure, sleep apnea, and joint pain.
Eli Lilly hit a record high this week after its triple-hormone shot, retatrutide, posted the largest weight loss ever recorded in a trial — about 28% of body weight — while also improving blood sugar, blood pressure, sleep apnea, and joint pain. The obvious question hanging over it is whether this is a longevity drug, or just a very good weight-loss one.

Senescent cells — worn-out cells that stop dividing but linger and leak inflammation — are a hallmark of aging, and researchers have begun charting their diversity across human tissues using single-cell mapping and AI, building an atlas meant to help target the harmful ones more precisely with senolytic drugs. In other words: the “zombie cell” story is getting less zombie, more taxonomy.
Gobble's Take: Precision beats vibes, especially when the goal is not merely to name the junk, but to pick the right junk.
