USNews is carrying an interview with Brian Alexander, author of Rapture: How Biotech Became the New Religion, focusing on the science of healthy life extension. There are a lot of ideas and a healthy amount of name dropping in there; the author has some interesting things to say about the backdrop to the current revolution in medicine. A quote: "Life extension already exists. Scientists have made lab animals live far longer than their natural life span, up to six times longer. Translating that to people will take a long time, but it will eventually be done."
