This week, we go back down under to explore the latest science from the land of kangaroos, bandicoots  and the world's largest radio telescope - the square kilometre array.  Chris goes on a tour of the universe from the comfort of the SciTech  Planetarium, meets Nobel Prize-winning scientist Barry Marshall and the fluffy marsupials under protection at Project Eden.  We find out why Australia is the perfect place to look further in to space than ever before, witness the battles between bee sperm and examine how tempting sharks with the scent of food can change their behaviour.
