For 17 years, nurse Karen Barry’s office at National Geographic headquarters has served as an important stop for journalists, photographers, and explorers in need of vaccines and medical advice before they set out on expeditions all over the globe. We’ll head down to the medical office to listen to her stories of helping explorers out in the field—and we’ll hear from one of her most frequent “customers,” Dangerous Encounters host Brady Barr, who over the years has dealt with multiple animal bites, parasites, and even a lost finger. For more information on this episode, visit natgeo.com/overheard. Want more?  Here are some more tips from Nurse Karen Barry for staying safe while traveling,  The snake that bit Brady Barr is an amazing creature. The reticulated python is the longest snake species in the world. They are commonly measured at 20 feet long, longer than a giraffe is tall.  When isolated, female reticulated pythons are able to give virgin birth, a phenomenon biologists call parthenogenesis. Also explore: Pythons aren’t venomous, but the venom of other snakes, as well as ants, treefrogs, cone snails, and many other creatures might just hold the key to the next medical breakthrough.
