Subscribe: http://bit.ly/iotbs_sub Twitter: @okaytobesmart ↓ More info and sources below ↓ Shows like The Walking Dead are full of hungry, mindless, surprisingly fleet-footed armies of brain-eating zombies. Could they actually exist? Are zombies real? Well, maybe if you're talking about zom-bees! This week I introduce you to some of nature's strangest mind-controlling parasites, who make zombies of the natural world. This one will make your brain tingle. That's just the awesome science, though… not a parasite. Promise!
