Host: Chris Mooney

Our guest this week is Cara Santa Maria, the senior science correspondent for the Huffington Post and the personage behind its "Talk Nerdy to Me" video series. Recent topics range from cannibalism, to the non-power of positive thinking, to the strange sex lives of animals, to the, well, bizarreness of creationism.

Cara has appeared previously on shows ranging from Larry King Live to Geraldo at Large, and has co-hosted an episode of Star Talk Radio with Neil DeGrasse Tyson. She was also recently seen hosting several episodes of The Young Turks' popular web spinoff series The Point. She tweets at @CaraSantaMaria, and you can find her videos at the Huffington Post's Talk Nerdy To Me.
