Mary Roach RETURNS to Weirdest Thing to share her new book, Replaceable You: Adventures in Human Anatomy! From this phenomenal new read, she discusses a section on breathing through your butt, a thing not only turtles can do, but also apparently humans. Plus, Rachel talks about the ancient (and DEADLY) origins of ice cream, and Lauren explains a strange, dark goop found on a research boat propeller in one of the great lakes. (Yes, we know it sounds like the premise of a new John Carpenter flick.) The Weirdest Thing I Learned This Week is a podcast by Popular Science.
