David Sinclair's XPRIZE Rejuvenation Plan Has a Proof Problem
The real story is not another anti-aging pill claim. It is whether whole-body rejuvenation can survive XPRIZE's measurement machine.

What Is Longevity Science? How Aging Biology Works, What Human Evidence Shows, and Where Claims Break
Longevity science is real. The hard part is knowing which claims have moved from mechanism to human proof.

ER-100 First Human Dosed: The Rejuvenation Test Has Left the Lab
The first human dosing of ER-100 does not prove age reversal. It starts the evidence clock for one of longevity's boldest ideas.
Semaglutide Failed in Alzheimer's. The Bigger Lesson Is About Evidence.
Two major Alzheimer's trials showed semaglutide did not slow clinical decline. The result is a hard lesson in what evidence can and cannot prove.

Longevity will not become serious medicine until it proves what its numbers actually mean.
Rapamycin Still Needs Human Proof
Rapamycin has real longevity science behind it. That does not make it a proven anti-aging drug for healthy humans.
Partial Epigenetic Reprogramming Human Trial: Longevity’s Reality Check
ER-100 is a narrow eye-disease trial, but it may be the first real test of whether cellular rejuvenation can survive clinical evidence.

Longevity Will Not Break the Planet by Itself. Frailty, Emissions, and Inequality Might.
Longevity does not automatically create planetary collapse. The real burden depends on whether extra years are healthy or dependent, low-carbon or resource-heavy, shared or stratified.
Biological Age Testing: What Epigenetic Clocks Can Tell You—and What They Can’t
Epigenetic clocks can be useful research tools and decent trend signals. They become dangerous when people treat them like destiny.
