Slay Your Paper Tigers

Slay Your Paper Tigers: Sure, we all know a pile of paperwork or a job interview is nothing like a bloody battle to the death with a saber toothed tiger - but do our bodies know that? Is our brain still wired for fight or flight regardless of the modern stakes? In this episode of Stuff to Blow Your Mind, Robert and Julie discuss how and why our brains interpret minor annoyances as ancestral enemies.

Blow Your Mind: Regurgitation Celebration (+ Vomit as Art)

While adult humans generally avoid puking as much as possible, a good upchuck is just another biological function for other creatures. In this episode of Stuff to Blow Your Mind, Julie and I present a vomitory smorgasbord of cud-chewing monkeys, acid-puking spiders, corpse-hurling vultures and even human mothers who chew food for their babies.

Double-Sex Chickens Wow Scottish Scientists

Forgive the exploitative (and awesome) headline, but it's Friday and I feel like we all might need a good scientific tidbit to carry with us to our various dinner parties, hot dates, family meals or Xbox Live gaming sessions. Live your life how you see fit, people, just make sure you talk about gender-bending chickens. As covered by NPR (and published in Nature), Michael Clinton of the University of Edinburgh studies these amazing chickens, which are known in sciencey circles as "gynandromorphs." I kid you not: they're split right down the middle. One side looks like a rooster; the other side like a hen. Seriously, look at the photo.
