Blinded by science! We chat with a veteran science writer about the complexities of invasive species, the existential dilemmas of climate change, and the fun of gaming out animal gladiator battles. Also: the healing power of TV shows about violent druglords, a rebooted She-Ra, people who can't stop climbing things, and an evil young, sweaty, sexy... Andy Griffith? With Brandi Brown, Mike Fotis, and guest Maggie Koerth-Baker of 538.com.
