Deep Dive: Curing Age At the Cellular Level

The billionaire bet to reprogram aging itself, and the science behind it.

The top technology entrepreneurs of our generation are investing billions into reversing aging. Each is betting that the best way to reverse aging is with cellular reprogramming: the process of resetting cells without changing their identity. The theory is that aging is partly driven by changes in how cells read and use their DNA, so resetting those instructions could restore function across many tissues at once rather than treating one age-related disease at a time. But there are significant risks with this approach. Most cells in the human body are specialized. They have specific jobs:…
