Episode 318 - Stubborn Moose, repulsive smells and Otters with tools

We recap March Mamma Madness Round 1, and look at some latest science stories that relate. From what happens inside your brain when you smell a repulsive smell, to making the right call on fleeing or standing your ground. Plus we look at using archaeological techniques to help understand the history of animal tool use like with otters.

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 313 - Cross continent pop hits from whales and deep divers

The greatest pop hits can cross continents, but what about oceans? We all know whales make songs, but not only are they very complex, they can be covered, repeated and spread like a Number 1 summer hit across oceans to the far flung corners of the globe. Plus reaching the deepest depths of the ocean is tough for humans, but easy for whales. How do they accomplish these great feats? We also touch on the impact of naval sonar on the battle between squids and whales.

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 308 - Farewell to phantom limb pain, and better prostheses

 Having a traumatic injury, serious infection or cancer is bad enough let alone if you have to have an amputation. But once that amputation has occurred how do you make life easier for the amputee? Prostheses are helpful, but they can require retraining your brain and lack the sense of touch. Plus phantom limb pain can make life painful and frustrating. This week we find out about surgical and biomedical treatments to help improve prostheses and give amputees better quality of life.

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 306 - Drones as a force for good and evil

Drones being used for good, and drones being used for evil. We look at ways that drones can help biologists protect, treat, regrow marine damaged ecosystems. Including IVF transplants for the Great Barrier Reef, sea-grass disease hunting drones and even drones to detect camouflaged birds in forests. We also look into the science behind drone defense and how we can protect our critical infrastructure from rogue drones.

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 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 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 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 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 291 - Concussion science, assessment frameworks and biomarkers

Concussions are a serious issue for everyone from the largest professional leagues to the weekend amateurs. The CDC has released some updated guidelines for assessing concussions and we dive into some new tests to help take the decision out of players hands and back it up with some sound evidence.

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

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.
