Radiolab marathon all day today

Minnesota Public Radio is playing a marathon of the NPR show Radiolab all day today. Hours of good, science-filled, story telling wonderfulness. Right now, at 12:32 central, they're doing a show about epidemiologists tracing the origin of AIDS back to the 1920s. Definitely worth listening to. You can listen to the entire marathon on MPR's live stream from anywhere in the world.
