0:03.7	Rob, everyone loves a deal and a bargain from time to time, don't they? Absolutely, mate. And you know where you can grab a great deal? Talk to me. Where? The eBay app. Yes, you are correct.

0:55.3	Cornell University anthropologist Meredith Small discusses some cross-cultural issues at the other end of the age spectrum in babies,
1:03.4	and Carnegie M. Greenger Morgan tells us about a startling new study of personal electronic devices on airplanes.
1:12.6	Plus, we'll test your knowledge of some recent science in the news.
1:16.6	First up, MIT's Lenny Guarente.
1:19.6	He spent the last 15 years studying the genes that regulate aging,
1:23.6	and he and David Sinclair wrote the cover story in the March issue of Scientific American about genes and aging and the implications of his research.
1:33.3	I called him in his office in Cambridge, Massachusetts.
1:36.3	Dr. Garante, thanks for talking to us today.
1:39.3	It's my pleasure.
1:40.3	You have the cover article in the March issue of Scientific american unlocking the secrets of longevity genes uh... let's talk
1:49.3	about the genetics of longevity conventional wisdom always had it that
1:53.8	aging was uh... function of normal maintenance mechanisms going awry as as you
