Baldrson writes, "Anti-aging researchers, via The Methuselah Mouse Prize or M-Prize, are receiving an additional $3 million incentive to stop and reverse aging. Researchers win M-Prize money in increments by breaking longevity records for mice or reversing their aging. The philanthropic donation comes from Peter Thiel, co-founder and former CEO of PayPal. Mr. Thiel has pledged to match each dollar donated to the M-Prize with his own 50 cent contributions up to $3 million." The M-Prize was created by Aubrey de Grey, a controversial biomedical gerontologist in Cambridge, England.
