The Science of Flight and the Colours of the Universe

Dave Ansell

We answer these questions on this weeks Ask the Naked Scientists.  We also find out if bigger brains means dumber people, if the use of polystyrene in our soils can poison our food and reveal how to move a tin can without touching it!
