i HIGHLY recommend every reader to check out WNYC's Radio Lab. it's a radio show on NPR and also Podcasted. it has to be one of the most interesting listens i've ever experienced.
Radio Lab® is an investigation. Each episode is a patchwork of people, sounds, stories and experiences centered around One Big Idea. On RadioLab, science bumps into culture… information sounds like music.
Radio Lab is designed for listeners who demand skepticism but appreciate wonder, who are curious about the world but who also want to be moved and surprised.

you can get info here:
the Podcast is available via iTunes (free, of course), just search for WNYC, or RadioLab, and you should find it.
incredibly fascinating stuff, totally captivating.
