Summary: This week, we have another special show from Perth in Western Australia. Chris Smith and Victoria Gill go in search of dolphins, find out how DNA sequencing technology has allowed us to find out what was on Australia's first barbecue, and give a science lesson to children in the outback. In the news, how glucose affects our willpower, why the Antarctic oceans are so different from the rest of the world, and the batteries that store power from renewable energy farms.
