On this week's episode the team take a break from guests and focus on what's got their scientific attention. Dr Shane, Dr Krystal and Dr Alicia talk about the possibility of Australia losing all its acacias (by definition) and the ethics (and outcomes) of Greenpeace destroying a genetically modified CSIRO crop. In addition to this they talk about tundra fires in Alaska, the pros and cons of coffee, how climate shifts are changing the wine industry and how volcanoes are possibly the cause of noctilucent clouds.
