Radiolab is easily some of the best media being produced in any medium these days, so you should all be subscribed to the weekly podcast of the show anyway, but I saw a discussion someplace online about this episode in specific, from July of 2007, that struck my fancy. The first piece is about sifting through ancient Greeks’ trash (and finding, among other things, biblical apocrypha, porn and comedy), the second is on a pile of letters discarded along Route 101 and the third is about tracing the family trees of Asian peoples and finding a common thread (more specifically, a common dude).

Saving this mainly for myself: Radiolab Detective Stories
