I find myself a little sceptical of articles on a website called "extreme longevity", to be honest...

... also, skimming the linked paper, the largest sample I see is "sixty rats randomly divided into 10 groups of 6 rats". I'm not sure if that's really large enough to draw any solid conclusions, and I don't see any P-values for the lifespan data -- but I freely admit I'm neither any kind of biologist nor a stats expert, so I may be talking rubbish.

Well, it was published in a real journal (Biomaterials) with an impact factor of 7.882. So the research is theoretically peer-reviewed and solid, in that the paper itself isn't just making things up.

Actually, that's one of the few reputable casual sites that cover the field of aging and longevity research, along with my own, Fight Aging!
