The first four teams have signed up to compete for the Methuselah Mouse prize for healthy life extension research. (Clicking on the "more" buttons on that page will tell you more about the competitors and their research backgrounds). Seven years ago, the X Prize was a $10,000 fund. Today it is a $10 million prize about to be won by one of more than twenty competing teams, so I see great things in the future of the Methuselah Mouse project. Have you donated yet? This is a great opportunity to help your future health and longevity.
