If you’ve never listened to WNYC’s Radiolab, today is a good day to get on the bandwagon because the new season of this fun, funny, fascinating, innovative, interesting show starts today. You can listen to the streaming episode at 3 p.m.

If you’re still on the fence, listen to my favorite Radiolab segment, the secret history of a box of letters found on the side of the road, and get hooked.
