Episode 288 - Tackling Fatbergs, Recycling Li-On_batteries and new uses for cooking oil

00:0000:00

Keeping the world clean is a tricky job. You have to fight fatbergs, recycle large amounts of mess and even keep tanks of food clean. Fortunately material scientists keep inventing new methods, and re-applying old ones to help improve our planet. From using old mining techniques to recycle lithium ion batteries, to using oils to keep food equipment clean, plus tacking the monsters of the sewer - fatbergs.

Episode 287 - Fighting back against fungal infections

00:0000:00

Everyone knows about bacteria and viruses, but fungal infections can also wreak havoc with our health. Since we know so little about them, fighting back is difficult. But we can learn a lot but diving deep into the way fungal infections are structured, how they fight back and how they fight eachother.

Episode 286 - Fields Medal 2018 - Solving problems in mathematics with tricks from other fields

00:0000:00

The Fields Medals for 2018 have been announced, and Australian Mathematician, Professor Akshay Venkatesh was announced as one of the four recipients. Mathematics can seem like a group of different and diverse subjects, but Professor Venkatesh's work tied different areas of mathematics together to use one toolkit to solve problems in another area. We dive deep into the complex world of mathematics and look at the Fields Medals 2018.

Episode 285 - Icey lakes on Mars, a planets worth of dust and unexplained oxygen

00:0000:00

We are often tantalized by the prospect of water on Mars, but thanks to a Teenage Satellite we have found lakes of water on Mars, just beneath the surface. Plus we find out where all that martian dust comes from and check in on everyone's favourite Comet, 67-p.

Episode 284 - Solar panels that work in the shade, using coal waste and greener concrete

00:0000:00

Solar Panels keep getting better, but what if we could have solar power even when it's very overcast? Plus is there a way to make concrete greener and less carbon intensive? What if one of those solutions also helped take care of waste product from Coal Power Plants? We look at innovative green technologies this week in Lagrange Point.

Episode 283 - Dust storms carrying life, harming life and engulfing a planet

00:0000:00

Dust storms can be hazardous, especially when they engulf an entire planet like on Mars. They can also carry pollution across national borders and contaminate wide areas. But Dust Storms may also hold the secret for how life can spread across vast deserts. This week we look at dust storms of this world and out of this world.

Episode 281 - Interconnections between animals, ocean currents, climates and ecosystems

00:0000:00

This week we look into three stories about how oceans tie our planet together. Our ecosystems are often linked in unusual ways that are not immediately obvious. Ocean currents can tie ecosystems across the world together, impacting migratory species, local environments and ecosystems. Sometimes these impacts are short term, other times they play out over years, decades and centuries.

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

00:0000:00

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

00:0000:00

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.
