Summary
What the if microbes held a grudge? We're thrilled to welcome Ethan Rappaport, theoretical ecologist at the University of Maryland, to take us inside the tiny turf wars happening in your gut. We imagine bacteria sharing grudges like social media reposts, passing weaponized DNA to their neighbors through tiny genetic pamphlets called plasmids. Before you know it, whole microbial nations could be declaring war on your intestinal lining until you hand over the cotton candy. So maybe skip the diet and keep those gut buddies happy! —— When she's not studying zombie fungus at Harvard or helping us break the universe every week, our very own Gaby Paniccia writes science fiction. Her short story "The Automatic Grocery Store" is now featured on the popular podcast Escape Pod!
