Scientific American's podcasts are interesting. I heard an interview with Eric Kandel, recipient of the 2000 Nobel Prize in physiology or medicine (for his work on memory) in the most recent podcast.
Scientific American editor and columnist Steve Mirsky interviewed Dr. Kandel, and the discussion covered Kandel's research, his personal background and their intersection. Kandel spoke "about what kinds of scientific investigation he [found] most interesting and worthwhile and where he would concentrate if he were beginning his research career today."
Synergy abounds, so Dr. Kandel is promoting his new book In Search of Memory / The Emergence of a New Science of Mind (review from J. Clin. Invest) , an excerpt of which you can read in the April/May issue of Scientific American Mind (online = abstract only).
