Episode 326 - Capturing, reusing, recycling and cleaning water.

Water is essential for life, but we need to take care of the complete water cycle. Treating waste water can help remove harmful pollutants from cosmetics and medication. Industrial processes and landfill can also make super salty water, that we need to clean before releasing. Without good water management then we can end up without water in times of drought, and in times of flood more water than we can handle. This week we find out about ways to better manage the most precious of resources, water.

Lagrange Point Episode 323 - Keeping your immune system in fighting shape

How can we keep our immune systems in fighting shape? What happens when our immune systems are responding well or are missing key genes? is there targeted gene therapies that can be used to help save lives of those most at risk from infection?  How does our body hunt down and stop Listeria in it's tracks? Plus undercooked wild game or pork can lead to parasitic infections, but how does the body fight back?

Episode 319 - Changing lakes and rivers in the Antarctic and Arctic. Plus carbon capture and storage

Trying to understand how the climate will change is difficult. For every big event like the break up of an ice shelf, there are thousands of little factors that play a role. Sometimes this little things turn into a torrent of a river, or a calm lake which can cause an entire continent to bend and flex. We find out about research into the Arctic Tundra and it's changing lakes which are one of the largest natural emitters of greenhouse gases. Plus ways to capture greenhouse gases and store them safely.

Episode 314 - Ancient life and life in extreme places

From the bottom of the ocean, to the earliest days of the earth, life has managed to not just survive but thrive. We look at several cases which change our understanding of the earliest life on earth and just what that might mean for understanding life on this planet and beyond. From moving life fossilised in mud, to using isotopes to study metabolism and discovering whole new methods of getting food, life continues to astound researchers with its inventiveness.

Episode 312 - Making water work for us in a Polar Vortex, Drought and Power plant

Water is essential for life, but if its too cold it can cause havoc on infrastructure. If it's too hot there is not enough to go around. If it's too salty its not good for organic material, and if its saturated with CO2 its even more dangerous. So how do we keep water working for us as our climate changes and we have more droughts, more polar vortexes and more power plants? This week we find out about advances in chemistry and materials science that can help make better use of water.

Episode 310 - Glial cells and Neurons, putting a stop to degenerative neurological conditions

A brain injury like a stroke or a neuro degenerative condition like Huntingdon's or Parkinson’s disease can be a long and arduous ordeal. It can be difficult to diagnose and there are no clear treatments, but scientists are working hard to solve it. We find out about the important role Glial cells play in supporting neurons and how things can go wrong if they are disrupted. We also find out about ways to use the abundance of Glial cells to make new neurons. Plus we get a better understanding of cell death and repair and the roll proteins can play in slowing down those processes to give your brain time to recover.

Episode 307 - Ancient druidic treatments, wasp venom and peptide cages

The arms race against antibiotic resistant bacteria continues. As the world faces down this challenge, we turn to stranger and stranger places for treatment. So how can you turn ancient druidic treatments into modern new antibiotics? How do you make wasp venom actually a useful treatment? Can you trap bacteria inside a cage and just starve them to this? This week we find out about the fight back against bacteria.

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.

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.

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

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.
