A Scientific American article on the same research with a useful comment here: https://news.ycombinator.com/item?id=13187302 https://news.ycombinator.com/item?id=13187302 Interesting bits: "In living mice they activated the four genes (known as “Yamanaka factors,” for researcher Shinya Yamanaka, the Nobelist who discovered their combined potential in 2006).
