I was flipping channels last night and caught the last 15 minutes of the Takei interview. Cool new show, I really like deGrasse Tyson. There was another hour show after that with Jimmy Carter and talking about parasites. Carter's project entails exterminating the Round Worm parasite. It is getting quite close to being eradicated, and it is one nasty critter.
