Ferns on the radio

Ferns will have their day on the radio next Thursday, November 19. If you live in Madison, tune in to WORT 89.9FM for Perpetual Notion Machine from 7-7:30pm, or you can listen live online at WORT's site, or you can download the show as a podcast afterwards. Yours truly will be the guest, talking about ferns, science-blogging, and my favorite passage in the Origin of Species (whose 150th birthday is coming up soon...).
