Metformin and the 2007 mouse lifespan finding
The Wikipedia aging research timeline marks 2007 as the year of first evidence that metformin, a diabetes drug, could extend mouse lifespan; the source describes metformin as a longevity candidate linked to the proposed TAME trial but provides no human lifespan data.
The Wikipedia article Timeline of aging research marks 2007 as the year of the first reported evidence that metformin could extend lifespan in mice.
The source describes metformin, a diabetes drug, as a longevity candidate studied in geroscience (the study of aging biology) both mechanistically and clinically. One can hypothesize that the 2007 mouse data helped shift interest in metformin from diabetes toward aging, but the source does not establish that causal link directly.
The timeline gives no details of the 2007 experiment: no authors, no mouse strain, no dose, no effect size, no replication data. Metformin is also associated with the proposed TAME trial, a clinical effort designed to test whether aging biology can be targeted in humans. The source provides no evidence on whether metformin extends human lifespan.

The edge captures a historically specific and dateable moment: a long-established diabetes drug entering experimental aging research on the basis of a mouse lifespan study, later developing into the TAME trial concept. The gap between that mouse result and any proven human benefit is itself informative and worth surfacing.
