Flexible electronics and phones sound like science fiction,but materials engineers are turning them into science fact. We find out about projects from across the world to make it a reality. From Australian flexible screens, to MIT's incredibly thin and exotic semiconductors to Purdue's paper based circuits for medical applications.

Self healing materials sound like science fiction, but how can we turn them into a reality? What does self healing even mean? We dive into the material science of self healing systems to find out what mechanism are used and how you can make a material heal. Plus we find out how you can make a self healing material out of common plastics using one of the weakest forces. Plus how scientists test and assess different materials including using....a crockmeter.

Exoplanets are home to some extremely out of this world chemistry. From raining diamonds, to gaseous iron and titanium, even to secret supplies of water. If we want to understand just how unique our place in the universe is, we can try and replicate the odd conditions of exoplanets right here on earth.

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.

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.

Everyone loves lasers! From science fiction to the military and even scientists in labs. This week we look at using lasers to solve some unusual problems. From something deceptively simple as how to describe a smell to the complexities of better data transmission over WiFi.

Now that China has banned importing rubbish, we really have to find innovative new ways to clean up our mess. We look at new solutions from dissolving plastic in enzymes, to making new steel from scrap cars to zero-waste phones.

How can we make wounds close and heal by sticking together better? Is there some kind of super strong glues that can help stick even when wet? What can we learn from spiders to help heal a broken heart? All these bio materials and more in this week's episode.
