Science: Winning tickets, Beethoven's genome, brain wave music

Science commentator Allan Blackman joins Kathryn with three great studies - one that details how many lottery tickets you'd need to buy in order to guarantee a win, another that has uncovered details about Beethoven's health through just a simple lock of his hair and how scientists reconstructed a Pink Floyd song just by using patients' brainwaves. Allan Blackman is a Professor of Chemistry, School of Science, Auckland University of Technology.
