Stopping the science that could stop the world
Summary
In the final episode of "Life from Scratch," host Meredith Hoddinott explores the existential risks of synthetic biology, focusing on "mirror life." Scientist Kate Adamala initially pursued creating mirror-image cells for medical breakthroughs but halted the project after microbiologist David Relman warned they could become unstoppable invasive species. The episode details how this discovery led to a global coalition of scientists calling for a moratorium on mirror life research to prevent catastrophic ecological and human health consequences.
