The popular “life extension” blogs have been lit up recently with exchanges related to a recent publication that reports that a homogenized solution of olive oil and C60 carbon buckyballs fed to middle age rats extends their lifespans by an average of 90%. If this result stands up it is truly amazing. Compared with other longevity interventions such as rapamycin feeding or calorie restriction which at best extend lifespans by 15-20%, the 90% figure is off the scale. So I decided to delve into the research literature to clarify what is known and what is not known about C60 carbon fullerenes as related to biological impacts and health. I report on this expedition here. I also chime in with my own hypotheses about the mechanisms through which the C60-olive oil cocktail extends rats lifespans, assuming it really does.
