Audible Talks to Technology Review's Young Innovators: Kristi Anseth

In the near future you might thank Kristi Anseth, 31, for your space age fillings. Anseth develops photopolymers, plastics that go from hard to soft when they are hit with ultraviolet light. Some of them might change dentistry, making it easier and faster to repair teeth. She is also working on photopolymers that wear away over time. So, a doctor repairing broken bones might not need to rely on braces or screws to fix a shattered femur; the photopolymer could support the bones until the body has a chance to heal. Anseth was selected to Technology Review's list of 100 Top Young Innovators. At the daylong conference announcing those chosen, Audible's John Barth sat down with this under 35, cutting-edge thinker to discuss her work. Technology Review is MIT's magazine of innovation.
