Episodes

  • Our vast underwater forests at risk

    Sep 18 2021

    If there’s one thing Australians know how to be smug about, it’s that our country is home to some of the most incredible ecosystems in the world. But today, we’re visiting one that is massive in size, massively economically important … and massively underappreciated, to the point that that you may never have even heard of it.

  • Startups, innovation and regional Australia

    Sep 11 2021

    Mention the term “startup” and your mind probably goes to Silicon Valley and high-tech computer science. But startups exist in regional Australia as well – and what’s more, they’re crucial to our future. This week, we’re hearing from Elena Kelareva on startups in Gippsland, in regional Victoria – and how getting away from preconceptions is one of the first steps to startup success.

  • Dogs, devils and contagious cancers

    Sep 04 2021

    Where does cancer come from? Well there are a few answers to that question – genetic changes, maybe it’s triggered by a virus.

This week, we’re hearing from Ruth Pye about this surprising thing that two species in very different parts of the world have in common.

  • How music affects your brain and body

    Aug 21 2021

  • The myth that Australia doesn't have earthquakes

    Aug 14 2021

    Did you know that across the Tasman, in New Zealand, some kitchens have roller cupboard doors instead of, you know, normal cupboard doors? It’s because of the earthquakes. Sometimes they’re so bad that your crockery can shake out of your cupboards and smash, and the roller ones prevent this. Lucky for us, earthquakes don’t really happen in Australia, so it’s not something we need to worry about. Right? Well… it’s time you met seismologist Dr Trevor Allen.

  • Tigers, leopards and unforeseen consequences

    Aug 07 2021

    If you had to pit endangered species next to each other in a contest of who was most good-looking, tigers would have to be pretty close to the top of the list. They’re gorgeous – and getting people on board with the idea of protecting them isn’t too hard. But what about the people who live on the edges of their habitat? This week, we discover that conservation is a noble goal… but it’s got to be done in partnership with local communities. Our narrator: Professor Wendy Wright from Federation U...more

  • Resilient farms and water worries

  • Hiding drugs in nanomaterials to repair brains

    Jul 24 2021

Our tour guide is Dr Kiara Bruggeman, who’s hijacking and hacking these nano-sized structures, in the hopes of helping stroke-affected brains heal.

  • How communities can recover from disasters like bushfires and COVID-19

    Jul 17 2021

  • Unseen minerals all around us

    Jul 10 2021

  • Food supply in a pandemic

    Jul 03 2021
