The Methuselah Mouse Prize is a contest designed to accelerate progress towards real longevity-enhancing medicine and promote public interest in research on healthy life extension. It is one of my favored charitable causes, and so I will be sending Methuselah Mouse goodies to all new donors to the prize fund over the next few weeks. The prize has accumulated more than $400,000 in cash and pledges since the launch in 2003, far outstripping the first year of public fundraising for the Ansari X Prize back in 1996. With your help I expect the Methuselah Mouse Prize to produce the same results for serious anti-aging science that the Ansari X Prize has for private manned space flight. So go ahead and donate!
