Naked Science Questions and Answers

It's an Extravaganza of Questions and Answers on the Naked Scientists this week as we take on your questions, including whether dogs can sniff out a seizure, what is fire made of, and how do glow in the dark objects work?  Also, we hear what an artificial tongue can tell us about speech production and the way to build superior voice recognition software, we rev up a system that can harness the waste heat in car exhaust to boost efficiency, find out how to flavour breast milk and hear why dolphins sing lullabies.  Plus, in Kitchen Science, Ben and Dave go for a drive with a helium filled balloon to uncover the basis of inertia!
