I listen to quite a few science related podcasts including Steve Mirsky's Scientific American podcast Science Talk, our own Robyn William's Science show on ABC radio national, The Naked Scientists from the UK. Others occasionally pop in there to be complemented by things like the Philosophers Zone and the ever popular Skeptics Guide to the Universe.
Anyhow I got onto this topic because I found myself at the New Scientist Youtube Channel. Because I was looking at these two videos showing off some robotics research. This field brings together design, clever thinking, engineering, AI and development into a potent package.
