Mirror cells could threaten life on Earth. Why are we building them?
Summary
NPR’s Shortwave explores the controversial concept of "mirror cells," synthetic organisms with reversed molecular chirality. Host Regina Barber interviews Carl Zimmer about a recent warning from biologists who fear these invisible-to-immune-system cells could cause catastrophic pandemics. The episode examines the technical hurdles to creating such life, the unprecedented call to halt research before it begins, and the ongoing scientific debate over potential risks versus benefits.
