Summary

Host Matt Gifford interviews Dr. Chung-Hong Cao, a mechanical engineering professor at McGill University, who won the Ig Nobel Prize in Technology for his team's "3D necro-printing" research. They discuss how the team repurposes dead mosquito proboscises as ultra-fine nozzles to print structures as small as 20 micrometers, a technique that could enable the creation of bionic contact lenses and other high-precision medical devices. The conversation also explores the value of curiosity-driven science, the origins of the idea, and the potential for future breakthroughs in preventing mosquito b…
