On Episode 5, a scientist named Trista Vick-Majors shared a first-person account of her team's quest to find out if there's life, deep beneath the ice in Antarctica. After the story aired, several listeners asked to know more about the discoveries that Trista and her colleagues had made. So we invited her back on the show.

In this episode, Trista explains how tiny organisms cling to life in one of the least hospitable places on the planet.
