A New Book On The Horrifying, Creative World Of Insect Zombies
It’s zombie season! At least if you’re watching the new season of the fungal thriller “The Last of Us,” airing right now on Max, which chronicles what happens after a fungus turns most of humanity into zombies.It’s fiction for us, but for some organisms on the planet, it’s more like a documentary. The fungus that zombifies humanity in the show is based on Ophiocordyceps, a real fungal group that infects ants, takes over their brains and bodies, and turns them into spore factories.But this isn’t the only example of real-life zombies. Science writer Mindy Weisberger found a whole book’s worth of stories about horrifying and creative zombies and zombie-makers that inhabit the Earth, which she writes about in Rise of the Zombie Bugs: The Surprising Science of Parasitic Mind-Control.Host Flora Lichtman sits down with Weisberger to talk about the creepy and inventive lifestyles of these parasites, and how studying these zombifiers can teach us about ourselves.Read an excerpt from Rise Of The Zombie Bugs.Transcripts for each segment will be available after the show airs on sciencefriday.com.
