In 2013, the cofounder of Google, Larry Page, announced that his company would form Calico and fund it lavishly to carry out a long-term project, trying to sort out the causes of aging and do something about them. The company’s mission: to build a Bell Labs of aging research. It hoped to extend the human life span by coming up with a breakthrough as important, and as useful to humanity, as the transistor has been.
There are reasons to think aging can be slowed in fundamental ways. Among Calico’s first hires was Cynthia Kenyon, now its vice president of aging research, who 20 years ago showed that altering a single DNA letter in a laboratory roundworm made it live six weeks instead of three.
