Not just any old mouse will do.

Interested in getting in on some big cash prizes but don’t have the sequencing capacity or rocketry experience to compete in the more well known X-prize competitions If you’re good with mice, all you might need is time. In putting together the March feature on aging by S. Jay Olshansky and colleagues we came across the Methuselah Mouse Prize or M-prize. Funded by private donors, the M-prize is brainchild of Aubrey de Grey, the Cambridge geneticist who contends that with proper maintenance (yet undiscovered), humans could live for hundreds or even thousands of years. The prize is awarded in two categories that have been variously named over the years but currently go by longevity and rejuvenation. . .

If you can double the current record of 1,819 days, you can capture half the available funds, currently $3.3 million.
