My talk with John Horgan on bloggingheads.tv is up. I'm sure the fact that the label "weird life" appears directly over my head was an accident (right, John?). Anyway, we had a good talk about parasites, aliens, and how to handle hype in science. I may have made some mistakes--feel free to fact-check in the comment thread. Unfortunately, I can't strike out my spoken errors, but we can make the best of it. (If you hanker for more scienceblog/bloggingheads encounters, see these talks by PZ Myers and Chris Mooney.)
