As a reminder to folks who read the Longevity Meme news via RSS, we also publish a newsletter containing site updates, commentary and news. You can receive the newsletter via e-mail or RSS feed. In order to somewhat reduce the size of each newsletter, we recently shifted from our traditional bi-weekly format to a weekly delivery schedule; it seems to be working well. As a further reminder, back issues of the newsletter can be found online: in the July 12th newsletter we let you know that Ray Kurzweil will be speaking about radical life extension tonight on NPR. Don't miss it!
