Episode 277 - Breaking down the brain and figuring out how the pieces work


Our brains are incredibly complex machines, running millions of calculations in no time at all. But how do these fantastic circuits work? If you follow AI and computer science you may have heard of a ''neural net'' style program which mimics how the brain learns, but really, how do the messages get passed between neurons along such networks? Does shape matter? Can we study individual pathways? What happens if you try and pulse the brain to give it a boost? We find out about neurons, their networks and more.

Episode 275 - Protecting biodiversity and ecosystems in flux


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.
