Jeff Bezos reportedly invests in Altos Labs, the latest startup trying to extend human life

Amazon ex-CEO Jeff Bezos has been looking to space for humanity's future. But the world's richest man is also trying to extend humanity's lifespan here on Earth, according to a report in MIT Technology Review. 

Bezos, worth an estimated $200 billion, is one of several investors in Altos Labs, a Silicon Valley startup working on technology to rejuvenate cells and potentially prolong life, the Technology Review reported. The startup also counts Yuri Milner, a Russian tech billionaire and founder of the $3 million Breakthrough Prizes, as a backer. Altos Labs is working on what's called reprogramming technology, a method of reverting adult, specialized cells into stem cells, which have the potential to turn into any kind of cell, according to the Technology Review.
