Episode 276 - Hunting for gamma rays

Monday May 28, 2018
Gamma rays are a mainstay of science fiction, but hunting for these elusive events is a lot easier with the right tools. We find out about two ingenious ways to hunt for gamma rays including flying into a cyclone, using satellites and even a telescope the size of New York.

Episode 275 - Protecting biodiversity and ecosystems in flux
Monday May 21, 2018
Monday May 21, 2018
Protecting biodiversity is important, but how well have we protected our critical zones over the past 25 years? Are predators invading human spaces or are they just reclaiming their old territory? What about places where the predator / prey balance is out of whack? We dive into biodiverse ecosystems across the world.

With Kilauea erupting, we look at the science of volcanoes and how we can keep better tabs on these rumbling giants of geology. From infra-sound monitoring, to tracking disappearing lava lakes.
