Animals That Eat Poop

Thanksgiving is a time during which many Americans eat things they shouldn’t -- so it’s a perfect time to discuss coprophagia in the animal kingdom. But, unlike many holiday dinners, these examples of poop-eating organisms are not exercises in dysfunction. In this episode of Stuff to Blow Your Mind, Robert Lamb and Joe McCormick invite you to join yet another feast of knowledge.

Cognitive Sewage: All Water Has Been Pooped In

You know how it goes. NASA creates an amazing new water filtration system and the headline winds up reading "Astronauts Drink Recycled Urine, and Celebrate." Try as we might, we just can't think about that fresh glass of filtered space water without slapping a mental "WARNING: PEE-PEE" label on it. No matter how much we purify it, we can't quite eliminate the cognitive sewage -- which is rather unfortunate given the looming world drinking water shortage.
