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.

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.

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.

How far would you go to find a treatment that helps you or a loved one suffering from a chronic condition? Is it worth the side effects or the pain of jumping through bureaucratic hoops? Is it worth risking the black market? Plus we find out ways to make precision medicine even more precise to rule out side effects.

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.

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.

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.

We check in on the latest research into the Zika Virus. How have our efforts to detect and treat this virus progressed since the outbreak of 2015/16? Are there new and novel ways of tackling Zika (and other mosquito born viruses) and can we make the Zika Virus work for us rather than against us?

This week we find out some strange and new ways scientists are hunting for a new weapons in the antimicrobial resistance arms race. Including turning to platypus milk for guidance, cooking the insides of bacteria like an egg and blocking it from even spreading. Plus we get an update on Mammal March Madness.

We find out about some amazing Australian biotechnology inventions from an efficient lab-on-a-chip, to boosting our immune systems and stopping bio-films in their tracks.

Mysterious creatures roam the depths of the ocean, from turtles to whale sharks. Studying their journeys shed light on the way our oceans are interlinked and the impact of climate change on the whole ecosystem.

Mysterious underwater caverns teeming with unusual life, and oceans trapped in time. We dive into the mysteries of oceans, caves and their hidden ecosystems.

Unexpected journeys in science from a link between quantum mechanics and proteins, to spider silk hearing aides. We hear how scientific research can start in one place and end far far away.
