Fungal parasites like the ones shown in The Last of Us might not be starting up a zombie apocalypse anytime soon but that doesn’t mean they’re not causing trouble in other ways. Host Dr. Samantha Yammine speaks with Dr. Carolyn Elya, a mycologist specializing in fungi’s unique ability to take over the brains of insects. They discuss how that compares with the fungal zombies in the show and whether concerns over fungal influence on our brains are legitimate. Sam also explores how researchers were recently able to bend soundwaves creating what they call, “Audible Enclaves.” Then, Sam answers the age-old question: how do mRNA vaccines really work?  

Tune into the second season of The Last of Us, premiering April 13th on Max.
