Hydrogen, HIV and Photographic Trickery - Naked Scientists NewsFLASH - 05.12.11 - a podcast by Dr Chris Smith

In this Naked Scientists NewsFlash, we hear how the Voyager missions can now detect radiation given out by the birth of stars, discover a new vaccine for HIV that can completely block infection in experimental animals, and explore the computer programme that can spot when a photo's been"photoshopped". Plus, we meet some clever birds and ask if heading a football can cause brain damage.
