The SENS Research Foundation, a charity funding research for treating-age related diseases, has received a $2.4 million Ether donation from Ethereum co-founder Vitalik Buterin, according to a press release on the charity’s website Friday, Feb. 1.

The foundation was co-founded in 2009 by Aubrey de Grey, a gerontologist who is researching rejuvenative therapies to extend people’s biological ages, hoping to permit humans to live much longer than ever before.

Buterin, who is quoted in the press release as a “fan of Aubrey’s work since [he] first read Ending Aging [de Grey’s book] as a teenager”, also said:

“I am happy to have been blessed with the opportunity to personally support SENS's efforts. Their focus on creating solutions to the diseases of aging, one of the greatest problems facing humanity, is very much in line with my goal to positively impact the lives of millions of people around the world.”

The SENS Research Foundation has already received two large donations totaling $2 million in Bitcoin (BTC) from the anonymous Bitcoin-only charity fund, Pineapple Fund — the first million dollars in December 2017 and another $1 million in BTC on Feb. 2.
