Episode 304 - Flexible electronics, graphene transfer and paper sensors

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.

Episode 303 - The risks of life in the big city from insomnia to cardio-metabolic health

Life in the big city can be fully of late nights, lots of lights and risky behaviour. This week we look at what living in the big city may mean for your health. Whether it be the impact of light pollution and getting a good night's rest, to the trade-offs of being a night owl, our circadian rhythms can be impacted by living a 24/7 life. We find out about studies on big data about a cities health, from a long term study of insomniacs in South Korea to using social media to determine when a city is 'feeling lucky' and willing to take a risk.

Episode 302 - Ancient empires changing the planet, leaving behind ruins and relics

This week we find out about ancient empires which have changed the face of the planet, changed the climate and left behind trophies of their conquests. From pyramid building termites in Brazil, to large climate changing colonies in Spain and even David vs Goliath battles in Florida with trophies of the dead.

Episode 301 - More effective Vaccines.

Using vaccines to tackle a pandemic is a serious challenge for health agencies. So how do we make vaccines more effective? Can we remove the requirement for a cold chain from lab to clinic? We also find out ways to boost the performance of a flu shot with a simple cream. Plus an update on a new vaccine types to prevent Ebola.

Episode 300 - Once in a blue asteroid, hidden objects in the Lagrange Point

In our 300th episode we return to our roots, the Lagrange Point. We find out about some odd objects hanging out at Earth's Lagrange Point, and how satellites can survive fierce solar storms only to be undone by a stiff breeze. Plus something rarer than a blue moon, a blue asteroid!

Episode 299 - Redefining the kilogram a history of measurement

Have you ever stopped to wonder what ruler rules them all? How we set the standard for height, for weight, for everything around us? What if you weighed one thing one day, and travelled to another country and suddenly gained 5 kgs or had to use an entirely different weight system? What if you weighed one thing this week and more the next? This week we find out the history measurement systems, how we've standardised them and come up with unique and repeatable measures that don't rely on artefacts (real and metaphorically).

Episode 298 - Self healing materials, scratch tests and the crockmeter

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.

Episode 297 - Antibiotic superweapons - hunter killer cells, dream teams and evolutionary history

Making new treatments often starts by finding out just what building blocks you have. But what if you could use the blocks with whole new sets? What if you could see how the blocks changed between owners? What about making your own brand new blocks? When fighting bacteria, we need every tool we can get. This week we find out about some great ways to take the fight back to bacteria in new and interesting ways from artificial cells, or new combinations of treatments, even to tracking the way bacteria changes over aeons.

Lagrange Point Episode 296 - Fighting back against hayfever, what histamines do for you, stopping travellers sickness

A change of seasons means you may be sniffling, sneezing and having teary eyes. So why do our bodies sometimes cause such an over the top response to pollen? We dive into the science behind hay fever, what histamine even does for you, and how it's helping you in more ways than you realise. Plus we find out what's being done to deliver a 1,2,3 blow to Traveller's Diarrhoea.

Episode 295 - Powerful and precise Lasers - Nobel Prize in Physics ‘18

Laser are used in some many things around us from computer storage, discs, communication, medical scanning and even laser surgery. Turning lasers from an expensive tool in the exclusive hands of large laboratories to something people all over the world can simply and easily use required groundbreaking physics. As did turning a laser into a pair of precise tweezers. For that groundbreaking research Arthur Ashkin, Gerad Morou and Donna Strickland won the Nobel Prize in physics in 2018. We find out about lasers, how they're used and how they were made powerful and precise.

Episode 294 - What is the biggest bird; Island Giants and dwarfs.

What is the biggest bird? Why do some species in some locations end up becoming giants? What makes islands like Madagascar so special and why are so many of the species once found there so very large in size? This week we look at island gigantism and island dwarfism across the world with a focus on the giant Elephant birds of Madagascar.

Episode 293 - Finding a fly in you drink, plus placebos on the brain - Ignobel Prize ‘18 Part 2

Can a single fly ruin a drink? How long does the fly even need to be in there to destroy the quality and taste? How does a fly even manage to ruin your sense of taste? These important questions were answered by the winners of the Ignobel Prize 2018 in Biology. 

Does having a more expensive label on something make it feel 'better' to eat, drink or use? What's going on in our brain when the "Label Placebo" effect takes hold? If you're an expert are you more easily swayed by the placebo than a regular person?

Episode 292 - Roller coasters for medical treatment - Ignobel Prize 2018 Part 1

It's Ignobel Prize 2018 time. As part of Improbable Research's celebration of curious and comedic science, we find out the rollercoasters, and how they are just what the doctor ordered. The Ignobel Prize 2018 in Medicine went to Mitchel and Wartinger for their ground breaking work into how to use rollercoasters to treat Kidney stones. We look into how rollercoasters work, their impact on the body, and how it can help pass kidney stones. Plus we look at some research into how rollercoaster g-force can impact your brain.

Episode 290 - The strange chemistry of exoplanets from their cores to atmospheres

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.

Episode 289 - Unlikely alliances, from ancient virus and Koalas to farming fruit flies and coral alliances

How do you defend against invaders in a millenia long war? Well Koala DNA is currently using some ancient DNA weapons to fight back against a viral invader. We also find out about some unlikely alliances from different corals teaming up, to how bacteria manages to spread and colonize from place to place. All this and more this week on Lagrange Point.

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

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

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

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.
