National Science Week, Year of Light and talking about curing cancer

Everything gets a little more sciencey in National Science Week, on from 16-23 August. We do a round-up of some of the top events around the country, and take a look at this year's theme for the International Year of Light.We also talk to lung cancer researcher Kate Sutherland about Science in the Square, celebrating 100 years of the Walter and Eliza Hall Institute of Medical Research (WEHI) and ask: will there ever be a cure for cancer?
