| Summary |
In this series return of Catalyst we look into tornadoes made of fire; whether it's possible to make a meal from fly larvae; and if dogs have empathy.FIRE TORNADOWe've all seen footage of out-of-control bushfires sweeping the Australian landscape, burning out hectares of native forest in their wake. But you might not have heard of a fire tornado, let alone seen one. For many years now researchers have theorised that fire tornadoes could be possible. Now, in studying the devastating 2003 Canberra bushfires, researchers have shown that fire tornadoes do indeed exist. During that tragic event, trees were uprooted, cars tossed, pine plantations flattened, houses destroyed and lives lost. Anja Taylor looks into the formation of fire thunderstorms and how they in turn can give rise to fire tornadoes, not to be confused with fire whirls.FLY FEEDMaggots...they make you squirm...but what a healthy meal they'd be: fly flesh encased in a shell. Inside the shell there is nothing but pure protein which magically reassembles to make a fly and that is why birds love them, it's why fish love them and it's why we're going to save the future with them. Over the next few decades the world will face a serious challenge...feeding the world in 2050. Waste-food recycling might be the answer. And that brings us back to the maggots. They live off rubbish, turning it into shells of nutritious protein. Of course we wouldn't eat them, but our farm animals could. Graham Phillips meets with Jason Drew who is behind a scheme to supply fly feed to agriculture and aquaculture.DOG EMPATHYDo dogs care? That is, do they truly feel someone's pain and know that it belongs to them. Dogs can quickly come to the aid of their owners if they are showing outward signs of distress, but are they simply mirroring their owner's distress and seeking comfort, or feeling their owner's distress and offering comfort? Jonica Newby conducts an experiment based on a test used to track empathy in humans to see if dogs truly have empathy |
