This episode, a tale of a wonder drug that will make you wonder about way more than just drugs.   Doctor-reporter Avir Mitra follows the epic and fantastical journey of a molecule dug out of a distant patch of dirt that would go on to make billions of dollars, prolong millions of lives, and teach us something fundamental we didn’t know about ourselves. Along the way, he meets a geriatric mouse named Ike, an immigrant dad who’s a little bit cool sometimes, a prophetic dream that prompts a thousand-mile journey, an ice cream container that may or may not be an accessory to international drug smuggling, and - most important of all - an obscure protein that’s calling the shots in every one of your cells RIGHT NOW. This episode was reported by Avir Mitra and was produced by Sarah Qari, Pat Walters, Suzie Lechtenberg, with help from Carin Leong and Rachael Cusick.
