Episode 510 - Fungi spreading across the planet and wiping out toxic soils

Fungi have an amazing ability to spread across continents but stay linked as a family lineage. Fungi can adapt to specific geographic niches in the same way as grapes. Different families of highly specialized mushrooms grow side by side across continents. How can fungi protect the plants it's attached to? Fungi often get a bad rap in farming, but they can be used to detoxify soils. Removing mercury and boosting crops; is there anything fungi can't do?

Episode 509 - What connects spicy food, proteins and your gut

How is your gut connected to the rest of your body? How does your nervous system connect to your gut? How can you sense pain inside of your gut? The bacteria that live inside your gut can call for help when under pressure. With the wrong balance of bacteria or signalling proteins our guts can be more prone for inflammation and damage. How can bad bacteria escape from the gut and evade detection? What enables some bacteria to sneak out of the intestine and wreck havoc.

Episode 508 - Finding your way as a fish along rivers and into the deep

How can fish keep themselves stable in a fast flowing river? What's the best way to stay on track as a fish? To swim straight ahead fish often end up staring downwards. The riverbed is way easier to track than a fast flowing current. How did fish manage to make their way into the deepest parts of the ocean? What climatic factors drove fish to explore deeper and deeper? What changed in Earth's history to encourage fish to thrive in the deepest parts of oceans?

Episode 507 - Peering beneath Mars’ surface

How does a single sensor help change your outlook on a planet? A single small seismometer on Mars can help understand Mars' past, present and future. What do an ultrasound and Mars have in common? Both can use a single sensor to peer deep inside. Listening to the echoes of marsquakes helps researchers understand what's in Mars' core. Modelling the inside of Mars' core helps researchers understand its past and future. Mars is often thought to be volcanically dead, but there are signs of some activity. A cluster of marsquakes can help researchers find evidence of vulcanism on Mars.

Episode 505 - Complex ocean currents sustaining life across the depths

Ocean currents can have global impacts shaping our climate and life in the seas and onshore. How do the ocean currents circulate and vary not just on the surface but beneath the waves? It's easy to picture different layers of clouds, but the same is true for our oceans. Large circulating patterns of currents called Gyres govern the oceans. Tiny phytoplankton keep our oceans alive but how do they get enough food themselves? The middle of a gyre gets baked in sun and seems to lack nutrient sources, so how do microbes survive there? When phytoplankton die they rain down nutrients and carbon to lower layers of the ocean as marine snow.

Episode 502 - Ignobel prizes ’22 - Blind dates and Mother Ducks

We celebrate the Ignobel prizes for 2022 with science that makes you laugh and then think. What connects a Fish, ducks and slipstream racing? How do mother ducks manage to keep all their ducklings in tow? Does swimming in formation help the ducks save energy? What's the best spot in the slipstream to be? We all know following in the slipstream is good, but if you're 3 or more back you can literally get pulled along. Complex fluid mechanics makes swimming in a line a way for a mother duck to pull the ducklings along. What happens physically when you find someone who is a good match? Is eye contact or heart rate a better measure of having  a 'spark' with someone new?

Episode 501 - The journey of the mandarin

Mandarin oranges are very closely related but also incredibly diverse. A quirk of cloning means we can accurately trace the journey of all mandarins back to their origins in Hunan province. Mandarins come in so many shapes and sizes and are used to celebrate by many cultures, but they all share a lot in common. Oregano and Thyme both produce some great smells, but these chemicals can carry a useful punch. How do Oregano and Thyme produce chemicals with antibacterial properties?

Episode 500 - Forest helping pump water and create rain

Plants harness the energy from the sun for so much more than photosynthesis. You have a beating hart to pump around your blood, but what do plants. Plants' vascular systems aren't pressurized so how do they power their circulation? Just how much energy do plants use globally each year to pump water out of the ground and into their leaves? Plants use incredible amounts of energy each year just to pump water out of the ground into their leaves. The fresh scents of plants are organic compounds that can reveal a lot about a plants condition. The scents of plants can play a role in influencing the climate around them.

Episode 499 - Air and atmospheres on exoplanets

CO2 gets a lot of bad press on earth, but in space, it could actually be incredibly helpful. On Mars, the Perseverance mission turned CO2 into Oxygen just like a tree. Making air on Mars requires a bit of Moxie and Perseverance. Mar's atmosphere may be thin, highly variable and full of CO2 but it can be harnessed to produce Oxygen. Could future mission to Mars make their own oxygen on the surface of Mars? Finding CO2 on exoplanets has been incredibly hard but the JWST helps shed light on this universal gas. Incredible hot, massive but not super dense, the Hot Jupiter WASP-39b becomes the latest target of the JWST. What can a hot Jupiter like WASP-39b teach us about exoplanet formation?

Episode 498 - Proteins, MRNA and fighting back against cancer

How can we develop new treatments to tackle antibiotic resistance and tumors. Antibiotics were the miracle of public health in the 20th century, but how can we establish new treatments into the 21st. Find the right protein and you can stop bacteria in its tracks by splitting it in two. New treatments can tackle antibiotic resistant bacteria by using proteins to break them in two. Cancer vaccines are benefiting from the mRNA revolution. A challenge with vaccines is that they can end up in the liver, so how do you get them to  deliver their instructions more effectively. Using special lipid nano particles, cancer mRNA vaccines can target the lymph nodes making for more powerful vaccines.

Episode 497 - Wearable med-tech inside and out

Wearable medical devices inside and outside of your body. Understanding what's happening inside your body can be tricky. Lugging around a scanning device with you all day isn't practical, but how can doctors tell what's happening in your daily life? Want to know what your organs are doing when you go for a jog or live your daily life? Wearable ultrasonic patches can give precise and long term ultrasounds making precise medicine possible. Stimulating nerves is a useful treatment for some conditions like Parkinson's or epilepsy but are very invasive. How can you use magnets to make these treatments much more friendly.

Episode 496 - Dwarf Planets and Massive collisions forming Moons

Dwarf planets are strange objects in our solar systems, but Ceres is unusual amongst that group. Why is Ceres' surface so strange and how could it have formed without a hot core? Ceres is too small to really have a molten core or large molten surfaces. How did Ceres end up with odd plateaus and continent like features without an active core? How could radiation cause Ceres to form in such an odd way? The Moon's relative size is puzzling but how can we prove that it was caused by a colossal collision?

Episode 495 - Plants without sunlight and electricity from sweat

How can we take ideas from nature and turn them upside down like growing plants without sunlight. There are some plants that thrive in 'low light' but what if they needed no light? Is it possible to change photosynthesis to work even without sunlight? Photosynthesis is great and all, but it's only around 1% efficient, so can it be improved? IF you were to make artificial photosynthesis can it outperform good ol natural sunlight? Biofilms are often the scourge of wearable devices, but what if they could help generate power? Turning sweat into electricity with bacteria could power your wearable devices.

Episode 494 - Mass extinctions and recovery in our oceans

What happens when most life in the ocean just dies off? Our oceans have seen many mass extinctions in the past, how long does it take to recover? What happened at the end of the Permian that caused massive extinctions in the ocean? What creatures were best able to survive when 80% of the rest of life in the ocean died? Burrowing and feeding on mud at the ocean depths helped soft bodied creatures survive a mass extinction. What lurked in the north Pacific that heated up the oceans? What was 'The Blob' and how were seals able to uncover it's secrets in the North pacific?

Episode 493 - Pleasant memories of sound and music relieving pain

There are plenty of tales of music soothing wild beasts, but is there actually a link between music and pain relief? How did researchers quantitatively study the soothing powers of music? What's better for blocking out pain ; Classical music, discordant arrangements or white noise? How does sound dull the effect of pain in mice? Just how good is a bat's auditory long term memory? can you train a bat to recognize the sound of a tasty treat? How do bats process and associate sounds with food?

Episode 492 - Finding hidden objects in the early universe

How can you find objects that are hard to see in the depths of space? There is plenty of gas in a galaxy, but trying to see a cloud amongst all those starts is not easy. The further back in time you look in the history of the universe, the colder and darker it gets. How do you figure out the structure of the earliest galaxies and their cold gas? A black hole roaming across a galaxy sounds like bad sci fi horror, but may have been found. How can you spot a black hole without any frame of reference? Detecting a roaming black hole is tricky but not impossible.

Episode 491 - Impacts and the messy history of the early solar system

The early history of our solar system can be deciphered by studying impact craters and meteorites. Craters on the Moon tell us a lot about the violent history of our solar system. Just how many impacts have there been on the Moon? We can study the porosity of the Moon to better estimate just how many impacts have occurred on it. How did Mars get it's atmosphere and from where? A Martian meteorite from deep in the core can tell us a lot about the solar nebula that formed our solar system. Mars formed relatively quickly, before the solar nebula dissipated.
