Can biology inform computing? Or computing help biology? Yes! Carl and Richard talk to MSR scientist Colin Gravill about biological computing. Alas, the conversation is not about making computers out of biological materials, but there is some discussion about using DNA to do some kinds of computing as well as building synthetic life from modified cells. Colin talks about the tools they're building to be able to simulate cell generations and understand how stem cells evolve into specialized cells. A cool technology/biology Geek Out!
