The Claim

Rapamycin extends lifespan in genetically heterogeneous mice, with statistically significant lifespan extension benefits observed in both male and female mice at each of three independent research institutions (The Jackson Laboratory, University of Michigan, and University of Texas Health Science Center).

What the research says

Supports is higher

Support is ahead, but a single strong opposing study can change this.

Challenges
0score

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

Cause and effect
1 study reviewed
In plain English

A drug called rapamycin helps mice live longer, and scientists have confirmed this works in three different labs - the results show both male and female mice benefit.

See the scientific wording

The lifespan extension effect of rapamycin is consistent across three independent test sites (The Jackson Laboratory, University of Michigan, and University of Texas Health Science Center) in genetically heterogeneous mice, with statistically significant benefits observed in both males and females at each site.

What the research says

1 study
  1. Study: Rapamycin fed late in life extends lifespan in genetically heterogeneous mice

    This study fed rapamycin to mice and found that it extended their lifespan. The researchers tested this at three different labs with genetically diverse mice and found the lifespan extension worked for both male and female mice at all three locations, exactly matching what the claim says.
