Episode 555 - Breaking down toxic fungus and learning to live alongside them

Young Scientists of Australia — Sun, 29 Oct 2023 01:12:57 +1000

Fungal invasions taking over living hosts is the thing of science fiction, but the humble button mushroom is taken steps to start. Often a fungi will specialize in symbiosis, invading or decomposing. But Mycena are starting to adapt to do all three. Humans, plants and fungi are in a complicated relationship where we influence the development of each other. The complex fungal toxin patulin is dangerous for humans, but can be broken down by microbes in soil. What can we learn from soil to fight back against fungal toxins and keep our fruit safe.

Episode 554 - Collaborating to solve Martian Mysteries

Young Scientists of Australia — Sun, 22 Oct 2023 02:16:39 +1000

What caused those large quakes on Mars? How can Mars have big Mars-quakes without plate tectonics? If an impact crater isn't too blame for the Mars quakes what may be the cause. An international collaboration pooled the instruments of many countries Mars Missions to solve a mystery. Even using many different countries space ships, no 'smoking crater' was found that caused a mysterious martian quake. How can we study the ancient martian rivers and oceans using data from old martian missions?

Episode 553 - E.coli to the rescue and boosting geothermal power

Young Scientists of Australia — Mon, 09 Oct 2023 17:12:41 +1000

E.coli is one of the most studied and versatile bacteria, so how can we make it work for us? Bacteria's ability to generate electricity is well known, but often requires complex conditions. How can we use E.Coli to generate electricity without a complicated setup? Geothermal systems seem to promise unlimited power but sometimes a cold water 'short circuit' ruins the plan. How do you carefully control the efficiency of geothermal power in the extreme temperatures and pressures of the earth?

Episode 552 - Talking to plants and how a jellyfish learns

Young Scientists of Australia — Wed, 04 Oct 2023 15:36:50 +1000

How does a jellyfish manage to see and learn without a large central brain? Like the Scarecrow of Oz, jellyfish are a without a brain but are still able to learn and do great feats. How does the nervous system of a jellyfish learn to dodge and avoid obstacles without a big brain? Plants respond to light, but is it possible to communicate with them about upcoming dangers?

Episode 551 - Boosting your immune system to fight back cancer

Young Scientists of Australia — Mon, 25 Sep 2023 17:13:44 +1000

There are many different types of treatments for cancer, all of them with pros and cons. Enhancing our anti cancer toolbox requires careful testing to help reduce side effects. CAR-T takes your immune cells and boosts them to help fight cancer, but can have some pretty nasty side effects. By carefully coating CAR-T cells you can fight back against cancer and limit the chance of a cytokine storm or neurotoxicity .

Episode 550 - Cosmic Collisions and galactic devouring

Young Scientists of Australia — Mon, 11 Sep 2023 01:38:12 +1000

What happens when two massive planets collide? How can you end up with a gas giant that's super dense and heavy? how can a planet the size of Neptune be as dense as steel? What happens when two giant planets collide at high speed? Watching a black hole devour a star, one bite at a time.

Episode 549 - Water infrastructure and Archaeology

Young Scientists of Australia — Fri, 01 Sep 2023 18:46:34 +1000

Infrastructure projects and large engineering projects can lead to archaeological discoveries. When you start digging a large sewer network, the last thing you suspect to find is 1,000s of fossils. Large water projects in Auckland managed to discover new species and shed light on New Zealand 3 million years ago. We often think of modern plumbing as being a sign of the modern era, but in ancient China, a community banded together to build their own drainage network.

Episode 548 - A paradise for Octopi at the base of a volcano

Young Scientists of Australia — Sun, 27 Aug 2023 23:17:23 +1000

At the depths of the ocean, in freezing waters there is somehow a paradise for Octopi. Off the coast of Monterey, an extinct underwater volcano creates just the right conditions for an absurd number of octopi to breed, nest and survive despite the freezing temperatures. With water near freezing, an octopi egg would normally take 8 years to hatch, but how are they managing to survive in huge numbers?

Episode 547 - Concussions - How long do you really have to wait?

Young Scientists of Australia — Thu, 17 Aug 2023 22:33:57 +1000

How long do you really have to wait after a concussion? Athletes are always keen to get back in the game after a head knock, but how long do they really need to wait? When trying to assess and track a concussion getting hard data is difficult. Using special headbands and measuring the pulse of the brain you can get an insight into concussion recovery. Concussion symptoms can disappear long before the brain has truly recovered. If you are slowly recovering fro a concussion how long will you need to wait?

Episode 546 - What’s going on with whale’s behaviour

Young Scientists of Australia — Fri, 11 Aug 2023 12:18:47 +1000

When whales and humans interact the results can be confusing and messy for both sides. Whether it be noisy boat propellers, or orcas on a collision course, humans and whales don't always get on. How can we monitor and track how whales respond to humans. The best ways of monitoring animals is often with tags, but the very act of tagging can ruin what you're trying to study.

Episode 545 - Phages taking the fight to bacteria

Young Scientists of Australia — Mon, 31 Jul 2023 22:48:27 +1000

Antibiotic resistance is a global challenge, but the solution may come from the natural predator of bacteria. Bacterial infections can be nasty, but you can engineer a phage to help better identify and treat them. Knowing exactly which bacteria is causing problems can help doctors target treatment more precisely and tailor antibiotic courses. Using bacteriophages you can quickly identify and then eliminate common types of bacterial infections.

Episode 544 - Metals recovering from fatigue

Young Scientists of Australia — Mon, 24 Jul 2023 17:05:40 +1000

Cracks in metal can ultimately lead to fatigue failure, but is there a way to unwind the damage? Fatigue failure is a serious problem for everything from bridges to phones so finding a way to tackle it is important. One microcrack can turn into another as a metal fatigues, but what if the cracks could close themselves up again? Can a metal piece itself back together again? Maybe if its in a vacuum.

Episode 543 - Monitoring vital signs without getting in the way

Young Scientists of Australia — Thu, 20 Jul 2023 11:41:53 +1000

Getting an accurate picture of someone's health or vital signs is essential in medicine, but hard to physically do without wires. Invasive health monitoring systems can't provide insights into 'everyday' scenarios. Trying to assess someone's posture, gait and rehabilitation is hard if they're wired into a harness. Smart Pants using fibre optics can help rehabilitation by fully understanding the problem points in high detail. Non-contact monitoring of breathing and other vital signs is important in a hospital setting to reduce risk, but camera based solutions are too variable. How can you 'remove the wires' in a hospital setting? By using LiDAR and RF radar.

Episode 542 - Evolving multicellular life in the lab

Young Scientists of Australia — Mon, 10 Jul 2023 18:55:55 +1000

Its a huge leap from a single celled organism to a complex multicellular beast. So how does evolution manage it? You can evolve humble yeast from a single celled organism into a complex interwoven multicellular one. Over 3,000 generations in the lab, the humble yeast was evolved from microscopic to macroscopic with super strength. Grouping together or splitting apart can offer benefits for organisms, but what environmental pressures cause an organism to go one way or the other?

Episode 541 - The building blocks chemistry

Young Scientists of Australia — Mon, 03 Jul 2023 22:20:20 +1000

Chemistry is complicated but it had to start somewhere. The origins of complex chemistry had to be built up from scratch. How did complex compounds form on early earth. How can we replicate the conditions of early earth and watch complex chemistry develop? Peering into chemical reactions is tricky because they can happen so fast.

Episode 540 - On the shoulders of giants

Young Scientists of Australia — Fri, 30 Jun 2023 23:43:10 +1000

The universe scaling work of the NANOGrav team stands on the shoulders of giants to understand giants lurking in our universe. Huge decade spanning scientific projects like NANOGrav are built of ideas and concepts which we can trace back to earlier pioneers. NANOGrav relies on Pulsars to map the universe but the discovery of them can be traced back to one key woman, Jocelyn Bell Burnell. This week we dive into the discovery of Pulsars and how they have been used to make a new way of looking at the universe. Finding a periodic signal in the noise can be helpful but a whole universe them of them can widen our understanding.

Episode 539 - Dangerous but beautiful space weather

Young Scientists of Australia — Tue, 20 Jun 2023 22:52:43 +1000

Weather in space, can seem far away but it's dazzling effects come with some danger. Aurora localised entirely around a satellite can cause a steamy situation for communications. Analysing space weather can lead to better designed satellites capable of withstanding 1-100 year solar storms. It's a balancing act when protecting satellites from solar weather, too much and too little protection can lead to disaster. Meteor showers are beautiful but how do you get one without an icey comet? The only way to get an asteroid to make a lovely meteor shower unfortunately involves a violent collision or big explosion.

Episode 538 - Colossal volcanic eruptions taking out satellites

Young Scientists of Australia — Mon, 12 Jun 2023 22:57:42 +1000

When a volcano erupts we're used to imagining damage from lava, ash and even tsunamis. So why were satellites taken out? The colossal eruptions at Hunga-Tonga in 2022 caused pressure waves that caused damage 1000s of km away and even to satellites. Satellites, long distance radio and GPS all rely on the ionosphere, but large eruptions can wreck havoc and cause disruptions. When a pressure wave spreads out from a volcanic eruption, we can also get similar disruptions to the ionosphere. Sometimes even before shock wave hits. The way our ionosphere protects and responds to stellar radiation can be influenced by big events down here on Earth.

Episode 537 - Better batteries that last even in subzero temperatures

Young Scientists of Australia — Tue, 06 Jun 2023 22:12:33 +1000

Batteries power the modern world, but how can we make them more sustainably and last longer. Lithium powers most of our modern batteries but it doesn't cope with the cold. The electrolytes inside lithium ion batteries are powerful but weak when its cold, so what can we use instead? Extracting lithium is carbon intensive and difficult, are there more abundant materials we can use? Calcium based batteries have a higher power density than lithium but finding a suitable electrolyte is a challenge.

Episode536 - Taking pollution out of the atmosphere

Young Scientists of Australia — Tue, 30 May 2023 00:53:38 +1000

Humans are filling the atmosphere with more and more pollution. How does it get out of the air and where does it go? For complex pollutants in the atmosphere, having a bit of hydroxide around helps break it down but where does it come from? Hydroxide can spontaneously generate in droplets but it doesn't seem to need sunlight's or photo-chemistry. Spontaneous generation of hydroxide in water droplets helps clean up our atmosphere. Which trees are best at cleaning up the air around them? From conifers to broad leave trees which help keep our air clean the best? C is for conifer, and their leaves and needles help capture pollution out of the air. Broadleaf trees are well...broad and this helps them capture lots of air pollution.

Lagrange Point Episode 535 - Trees growing faster during droughts

Young Scientists of Australia — Wed, 24 May 2023 23:53:58 +1000

As our climate changes extreme weather events become more common, but what does this mean for ecosystems? Ecosystems and plants that have adapted to on extreme climate, can thrive in another. An adaption that helps you survive in extreme cold can be very helpful when there is a drought. There is a balancing act between choosing when to grow and when to conserve energy. Plants carefully manage their resources in extreme drought and extreme cold.

Episode 534 - Finding a rocky asteroid belt around another star

Young Scientists of Australia — Tue, 16 May 2023 01:04:59 +1000

Asteroid belts are harder to find than Sci-fi would have you believe. Spotting an asteroid belt is easier in the outer solar system, but closer in it gets a bit more blurry. Using the JWT we can use more than just visible light to find tricky interstellar objects. Asteroid belts are messy but they can tell us a lot about a solar system by what they leave in their wake.

Episode 533 - Bacteria melting ice and changing the planet

Young Scientists of Australia — Fri, 12 May 2023 00:35:53 +1000

How can tiny bacteria change the entire planet? Greenland is beautiful and covered in glaciers, but they are turning more and more dark and black. Black algae is tinting glaciers in Greenland darker, and causing changes in our climate. The more our climate changes, the easier it is for algae to thrive in glacier runoff and change the colours of the glaciers. Algae can survive in strange locations on earth, what can that teach us about microorganisms across the solar system?

Episode 532 - Bacteria reviving themselves when the time is right

Young Scientists of Australia — Thu, 04 May 2023 22:23:31 +1000

Bacteria are masters of survival, pausing and shielding themselves when times get tough. So how do they know when to wake up? The mechanisms bacteria use to survive harsh conditions are one of the reasons they're able to survive so well. The protective layers and pausing all activity inside the cell enable the bacteria, as a spore, to survive very long periods of time. After suspending themselves through a tough period of time,how do bacteria wake themselves up?

Lagrange Point Episode 531 - Measuring the expansion of the universe

Young Scientists of Australia — Mon, 24 Apr 2023 20:00:24 +1000

Understanding the future of the universe requires peering into the past. How quickly the universe is expanding has been an active area of science since the 1920s, with several prizes and breakthroughs. Each time we get new or more accurate measurements it forces scientists to re-evaluate the assumptions and formulas. These breakthroughs then need to be confirmed with follow up studies. The measurement of Hubble's constant using supernova won a Nobel Prize in 2011, and new gravitational lensing measurements have provided extra confirmation to those numbers. Dark matter can influence a lot in our universe, but measuring it is difficult but using lensing techniques a more accurate measurement can be derived.

Episode 530 - Fully recyclable electronics

Young Scientists of Australia — Mon, 17 Apr 2023 19:05:47 +1000

Electronics power the modern world, but they come at a high environmental and energy cost. E-waste a serious problem as many of the elements in modern electronics cannot be easily recycled. Is there a way to produce electronics that are more environmentally friendly? Is it possible to make a circuit board or more simply even a transistor that doesn't rely on silicon? Can you imagine a Silicon Valley without actual silicon? Its possible to make recyclable electronics without silicon and instead relying only on carbon and cellulose. How can you get away from the use of chemicals or high heat in circuit fabrication?

Episode 529 - Listening in on conversations inside your body

Young Scientists of Australia — Mon, 10 Apr 2023 23:17:22 +1000

Your body is constantly communicating about what's happening outside and inside of it, but how can we listen in. When your immune system is responding to a virus, or a wound is healing, there are lots of signals to decode if only we could hear them. By amplifying the signals inside your body with special folding DNA and transistors we can understand how our body responds. The brain's neural networks are a treasure trove of information if we're able to blend in and listen. Using a microbot you can get precise information from on inside in the brain rather than relying on external information.

Episode 528 - How our senses pass information to our brains

Young Scientists of Australia — Thu, 06 Apr 2023 22:25:14 +1000

How does your body pass information along to your brain? The thalamus connects those sensory inputs back to your cerebral cortex but it's a lot sparser than you'd think. The synapses that link your senses to your cortex are often weak and rare, but their diversity gives them a boost. Lots of diverse synapses with different strengths help you perceive the world more clearly. Do both your eyes get equally treated by your brain?

Episode 527 - Concrete in space from blood, sweat, tears and chips

Young Scientists of Australia — Mon, 27 Mar 2023 17:06:57 +1000

Building a habitat on Mars or the Moon is hard work, but it's a lot easier if you can make your own building materials. Animal blood has historically been used as a binding agent for mortar, so could human blood help on Mars? You can make your own building materials on the Moon or Mars that are far stronger than on earth especially if you add tears and blood. Maybe you don't want to use blood in when building your martian home, but would you sacrifice your potato chips? Potato chips and some extra salt will can make for super strong building materials on the Moon or Mars. Is there ways to enhance the performance of concrete by using other industries waste byproducts? All waste has to be re-used when you're in space, but here on earth using waste water and waste steel can help boost concrete.

Episode 526 - Capturing biological process in action

Young Scientists of Australia — Mon, 20 Mar 2023 16:42:12 +1000

Seeing how something happens makes it much easier to understand. Biological process can be very hard to capture with images or video. Understanding how a protein requires thinking in 3D but to take images of them we often have to 'snap freeze' them in place. How can lasers, ions and quantum mechanics be used to help capture a protein in motion. PCR based diagnostics tests are accurate but require a lot of setup and expertise. Can you make a PCR test more like a point of care test using bio-luminescence.

Episode 525 - Life in a radiation exclusion zone and #2023MMM

Young Scientists of Australia — Mon, 13 Mar 2023 17:57:01 +1000

Life in a radiation exclusion zone is challenging but not impossible. We find out about tales of survival, endurance and adaption in radiation zones and in March Mammal Madness. How does life adapt to high exposure of toxic chemicals, radiation and heavy metals? Studying the DNA of differing animal populations in Chernobyl helps researchers understand how life responds to environmental disasters. What's more stressful for wild boar - humans or a radiation disaster zone? Around Fukashima wild boar and snakes are thriving in what is classified as a radiation disaster zone. We also preview March Mammal Madness and find out about the different divisions in this year's edition.

Episode 524 - Bacteria’s sneaky 1-2 punch to get into your brain

Young Scientists of Australia — Mon, 06 Mar 2023 17:35:39 +1000

Bacteria uses a clever 1-2 punch to make it through our central nervous systems defenses. The way bacteria can get through the outer layers of the meninges relies on knowing exactly what how the brain will respond to infection. Painful headaches are a key part of meningitis, but that pain response is actually opening the door for a sneak attack. Understanding how bacterial infections get into the brain will help develop new treatment pathways for meningitis. When bacteria come under attack themselves, they use signalling pathways that we can learn from. By studying the way bacteria defend themselves we could find common tools to use to precisely regulate human cells.

Episode 523 - Sinking carbon out of seawater and carbon storage in wood

Young Scientists of Australia — Mon, 27 Feb 2023 21:27:37 +1000

Our oceans and waterways are our largest carbon sinks and they're overflowing with CO2. Too much CO2 in our waterways can cause tremendous local damage, but there may be ways to clean that up. Using a cyclic process without messy membranes you can get water to release the CO2 captured inside. Extracting excess CO2 from oceans could be possible with only some clever chemistry cells with no waste byproducts. Now that you've got CO2 out of the ocean, what are you going to do with it? Make it work for you. Carbon sequestration can be more useful than just pumping it into the ground. With the right techniques you can use excess CO2 to improve construction materials.

Episode 522 - Making hydrogen greenly from Seawater

Young Scientists of Australia — Mon, 20 Feb 2023 16:21:14 +1000

Hydrogen comes in all kinds of colours but what does that mean? Hydrogen has a role to play in a decarbonised world as long as we can produce it greenly. It's no good producing green hydrogen if you use up another valuable resource or create another kind of waste. Water water everywhere, but not a drop to electrolyse. Using seawater to make hydrogen has challenges. How can we use the abundant seawater resource to make green energy sources without producing nasty by products?

Young Scientists of Australia — Tue, 14 Feb 2023 09:49:24 +1000

Using the JWST to peer into the Cosmic dawn of the universe. The JWST enables researchers to peer into the earliest galaxies in our universe. 250 Million years is not a long time when it comes to a star or galaxy. With JWST researchers can see galaxies formed 250 million years after the Big Bang. To peer into the earliest universe you must use infrared to capture the faintest light. Using new instruments on the JWST researchers are able to see galaxies from 13.25 billion years ago. JWST also lets researchers investigate strange new types of spiral galaxies from the Cosmic Noon.

Episode 520 - There and back again - tales from a wandering space probe

Young Scientists of Australia — Mon, 06 Feb 2023 13:48:36 +1000

Hayabusa2 had an exciting voyage across our solar system, getting into dust ups and even coming back home again with data to share. We've been tracking the long journey of Hayabusa2 over the 10 years of this podcast, and we're now getting interesting data from the returned samples. The Hayabusa2 probe shot at the asteroid Ryugu and brought back proof for JAXA to study and it tells tales of a very early time in our solar system. Ryugu is much much older than we thought, born only 1.8 million years after the formation of our solar system. How does a planetary system form and why are some planets in a flat line and others really odd. Our Nepture is an anomaly not just in our solar system but also compared to others. What happened to all the other 'Hot Neptune' exoplanets? Did they get burnt off or flung away?

Episode 519 - Evolving beaks and wild chickens

Young Scientists of Australia — Mon, 30 Jan 2023 21:28:41 +1000

How did birds end up with their trademark beaks? You can broadly group birds into two categories, ancient and modern jaws or beaks. We thought mobile beaks were a modern invention but new fossils overturn this idea. Just when did birds first develop their modern mobile beaks? Wild jungle fowl were domesticated to become the chickens we love today. But wild chickens are not isolated completely from modern ones. Gene transfers between wild and domesticated chickens are eroding the genetic diversity of the species.

Episode 518 - Aurora on Jupiter and on Earth

Young Scientists of Australia — Mon, 23 Jan 2023 16:19:14 +1000

Aurora are stellar examples of high energy physics. You need to be at the right spot to find Aurora on earth, but its not quite the same on Jupiter. What governs where and how an aurora will form? Earth and Jupiter are very different in size and speed, but why are our Auroras so different? How does Jupiter's magnetosphere bring all it's moons into line? What happens when an small independent moon brushes up against a super sized neighbour? Ganymede has it's own indepedent magnetic field. So what would happen if it got gobbled up by Jupiter?

Episode 517 - Cute green balls of algae and a changing climate

Young Scientists of Australia — Mon, 16 Jan 2023 21:34:30 +1000

In the northern reaches of Japan in a idyllic lake, cute green balls of algae are battling for survival. It sounds like an anime, but cute green algae balls, Marimo, are battling stellar forces. Too much sunlight can endanger the cute green algae balls, the Marimo. Having too much sunlight can be just as bad for algae as too little. How can brown algae help fight back against climate change? Algae have changed the climate once before, so can they do it again? If you were to quantify the carbon sequestration of algae, would it really make an impact globally?

Episode 517 - How our body senses and interacts with the world

Young Scientists of Australia — Mon, 09 Jan 2023 17:24:11 +1000

Understanding how our body senses and interacts with the world. Scientists are only now beginning to understand how our body senses the world, hence the '21 Nobel Prizes. This Nobel prize wining research helped others find a connection between the gut and our sense of touch. Internal organ pain can be crippling and require side effect laden treatments. How do organs like the gut detect and transmit pain signals? The same mechanism to detect soft touch is used by your organs to send pain signals. How does our body precisely control temperature? What region of the brain measures and control what temperature to set itself to?

Episode 516 - How plants handle too much or too little light

Young Scientists of Australia — Mon, 02 Jan 2023 18:23:46 +1000

Too much or too little light can cause serious problems for plants. Light levels are not simply a feast or famine equation when it comes to photosynthesis. Plants must carefully manage the amount of light coming in to ensure smooth photosynthesis. The way genes in leaves responding to rapidly changing light conditions help them make the most of photosynthesis. Your eyes have to rapidly respond to opening curtains in a dark room, just like leaves of a plant. What about plants that have abandoned the need for light at all? Can a plant survive or thrive without light or photosynthesis?

Episode 515 - Do you really need oxygen for oxidation

Young Scientists of Australia — Mon, 26 Dec 2022 22:12:57 +1000

How does chemistry change when you travel to another planet? When it comes to scientific experiments often we can be hampered by our own experience. Just because something is abundant on earth does not meant that it's a universal constant. Out of this world chemistry is hard to get your head around and it requires thinking outside the box. Is it possible to have oxidize minerals without oxygen?

Young Scientists of Australia — Mon, 19 Dec 2022 23:01:43 +1000

What happens when you push water to the limits on earth and in Space? Water has really weird properties especially when it gets really cold. How can we understand and model the behaviour when it moves to fast for us to capture? How do droplets form and why do you need the ISS to study it? What can microgravity tell us about the way droplets form?

Episode 513 - An eerie glow in the Solar System

Young Scientists of Australia — Mon, 12 Dec 2022 15:13:19 +1000

How do you measure the solar system and the universe whilst being inside of it? Too much light is a problem for astronomers and our solar system has it's own glow. If you take away all known light sources form the solar system, there is still a faint glow. We know about background radiation, but what about the solar systems background lighting? How can you test the curvature of the universe? To answer universal scale questions you need to start small. Really small. Using Bose Einstein condensates and getting really cold we can simulate curved universes in a molecule scale.

Episode 512 - Analyzing aftershocks and predicting earthquakes

Young Scientists of Australia — Mon, 05 Dec 2022 15:37:41 +1000

Forecasting an earthquake is serious business, but it's not like the weather. Why are earthquakes so hard to predict? Knowing when an earthquake will occur is hard enough, but what about predicting aftershocks? Aftershocks can create huge stress and compound damage after a quake so what can be done to predict them? Building huge scale models out of granite can help researchers better understand aftershocks. Sliding slabs of granite, plastic blocks and quartz dust help researchers understand aftershocks. When an earthquake combines with another disaster, the compound effect is devastating. How good are modern risk assessment tools at managing compound disasters?

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

Young Scientists of Australia — Mon, 21 Nov 2022 21:38:44 +1000

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

Young Scientists of Australia — Mon, 14 Nov 2022 16:00:02 +1000

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

Young Scientists of Australia — Mon, 07 Nov 2022 17:50:40 +1000

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

Young Scientists of Australia — Mon, 31 Oct 2022 18:07:53 +1000

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 506 - Assimilating all microbes in it’s path to chow down on Methane

Young Scientists of Australia — Mon, 24 Oct 2022 22:46:08 +1000

How have microbes changed the course of life on our planet? How has our atmosphere changed as a result of bacteria and archaea? Assimilation can help enhance single cellular life. Archaea can collect long strings of extra genes just in case. Finding the right gene at the right moment can help Archaea make the most of available food.

Episode 505 - Complex ocean currents sustaining life across the depths

Young Scientists of Australia — Mon, 17 Oct 2022 21:52:07 +1000

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

Young Scientists of Australia — Mon, 26 Sep 2022 21:13:30 +1000

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

Young Scientists of Australia — Tue, 20 Sep 2022 08:03:03 +1000

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

Young Scientists of Australia — Mon, 12 Sep 2022 22:27:33 +1000

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

Young Scientists of Australia — Mon, 05 Sep 2022 22:07:27 +1000

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

Young Scientists of Australia — Mon, 29 Aug 2022 19:31:09 +1000

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

Young Scientists of Australia — Mon, 22 Aug 2022 23:18:26 +1000

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.

Young Scientists of Australia — Mon, 15 Aug 2022 23:36:39 +1000

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

Young Scientists of Australia — Mon, 08 Aug 2022 22:55:16 +1000

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

Young Scientists of Australia — Mon, 01 Aug 2022 21:28:41 +1000

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

Young Scientists of Australia — Mon, 25 Jul 2022 21:57:41 +1000

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

Young Scientists of Australia — Mon, 18 Jul 2022 17:25:58 +1000

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

Young Scientists of Australia — Mon, 11 Jul 2022 17:20:26 +1000

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.

Episode 490 - The history of fire on Earth

Young Scientists of Australia — Mon, 04 Jul 2022 18:30:43 +1000

The history of fire on earth from the first wildfires to the first use to cook. We all know you need fuel and oxygen for fire, but when did the first fires occur on Earth. When did the first wild fires occur on earth? What was there to burn on early Earth if there weren't any large trees or plants? Giant mushrooms and large fields of moss, early Earth was very different but it could still have wildfires. When did the first hominids use fire as a tool? How can we identify if something that was burn was done so deliberately or accidentally. We know at some point hominids used fire as a tool, but when exactly - 200,500 800 million years ago?

Episode 498 - Clean air, captured carbon and paper sensors

Young Scientists of Australia — Tue, 28 Jun 2022 06:30:58 +1000

Where is the cleanest air on the planet? How do oceans help capture carbon from forest fires? Where does all that carbon go after a forest fire? How do you find the cleanest air, by measuring microbes. The southern ocean air is not polluted by aerosols or ice forming particles. The air above the Southern Ocean is clean and crisp with not much microbes in side it. How can you turn a paper into a simple carbon dioxide sensor?

Episode 488 -Mysteries from the formation of our solar system

Young Scientists of Australia — Tue, 21 Jun 2022 06:44:34 +1000

From cosmic rays in Antarctica, to chasing Eclipses to learn about stellar weather. Neutrinos are hard to track and detect, as are cosmic rays. Neutrinos suddenly coming out of Antarctica baffled scientists hunting for cosmic rays. Underground glacial lakes, compacted snow, cosmic can help explain mysterious neutrino emissions. Tracking eclipses and gathering data over 20 years can help us understand stellar weather. By studying the Sun's corona, scientists can better understand the magnetic field and stellar weather. The sun changes activity over 11 year cycles, and it's magnetic field also rearranges itself from highly structured to loose and messy.

Episode 487 - Feeding the planet without damaging it

Young Scientists of Australia — Tue, 14 Jun 2022 06:18:59 +1000

As our climate changes, feeding the planet without making things worse is a big challenge. How do plants work together to survive extreme weather events? When there is a large drought or extreme weather event what works better, single species or mixed? Plant diversity can help plants weather the storm of climate change and come out stronger. How do cover crops help 'fix' nitrogen in the soil and reduce negative climate impacts. Excess fertiliser is not only expensive for farmers but damaging to the local and global environment. How can cover crops help soil recover and reduce negative climate change impacts of mono cropping.

Episode 486 - Bypassing the brains defences for treatment

Young Scientists of Australia — Tue, 07 Jun 2022 06:36:09 +1000

The brain is incredibly important and needs to be protected by your body but this also makes it hard to treat. Brain tumours can be stubborn to root out because many treatments are blocked by the blood brain barrier. The blood brain barrier blocks many cancer treatments, but with the right disguise and nano coating cancer treatments can sneak past. Brain tumours can block the immune system from functioning, but sneaking through the right treatment can help the immune system fight back. Traumatic brain injury and subsequent inflammation can lead to significant damage, and normal anti-inflammatory methods are blocked by the blood brain barrier. If you can't sneak anti-inflammatories through the blood brain barrier, why not just boost their production locally? T Cells can fight back against inflammation after a traumatic brain injury if there's enough food for them to thrive on.

Episode 485 - Plants race against rising sea levels

Young Scientists of Australia — Mon, 30 May 2022 21:04:37 +1000

How can plants adapt to a changing climate and strange volcanic soils. By tracking the divergent evolution of Thale Cress, scientists can track the genetic changes needed to thrive in weird soil. Volcanic soil can have benefits along with risks, but how can plants adapt quickly to odd soil types? How did plants learn to thrive on a volcanic island, Pico de Fogo. What can a long running study tell us about plants adapting to a changing climate. Extra CO2 is good for plants...to up to a point. For plants in wetlands its a race between rising sea levels and extra CO2.

Episode 484 - The links between the Core and the volcanos on the surface

Young Scientists of Australia — Tue, 24 May 2022 03:45:03 +1000

How do seismic waves travel through our planet? Is it possible to 'slow down' a seismic wave? What causes 'hotspot volcanoes'? What strange things happen at the boundary between the core and the mantle? The mantle is a dynamic place, and pockets of 'dense' rock can slow and shape heat flow from deep below to the surface. Dense iron rich pockets of rock at the edge of the Core could influence where hotspot volcanoes occur.

Episode 483 - Constantly changing moons of Jupiter

Young Scientists of Australia — Mon, 16 May 2022 23:04:23 +1000

Jupiter's moons may be way more dynamic than we previously thought. Europa has the most potential to harbor life outside of Earth, but it's ice sheets may be more Earth like than we imagined. Europa's spectacular double ridges are similar to those found in Greenland. The ice sheets on Europa may not be static and still, but churning. Melting and refreezing could drive exchange between the surface of Europa and it's icey depths. How do you form sand dunes without any wind? Is it possible to form a Dune on Io using just volcanic flows and sulfur snows?

Episode 482 - Nova and Micronova not quite super still immensely powerful

Young Scientists of Australia — Mon, 09 May 2022 18:53:46 +1000

Supernova get all the press, but Nova and Micronova are still pretty powerful. White dwarf stars are normally pretty inactive, unless some hydrogen ends up kickstarting them again. Enough helium leeched from a nearby star can ignite the entire surface of a white dwarf. Nova may not destroy the star, but they can create immensely powerful explosions and particles. The right combination of White Dwarf and Red Giant can create powerful particles near the speed of light. Micronova sound small but they are still colossal and brief explosions on white dwarf stars. Not powerful enough to ignite the whole surface of a star, but definitely enough to destroy a planet, micronova are quite deadly.

Episode 481 - Finding hidden life in our oceans with RNA and DNA

Young Scientists of Australia — Mon, 02 May 2022 20:26:50 +1000

Using sequencing techniques we can find all kinds of hidden life in our oceans. RNA viruses are ancient, but their old genes can help us spot them in great numbers in our oceans. There are huge amounts of 'life' in our oceans that we don't know about. No matter if you think viruses are 'alive' or not, there are way more than we imagined in our oceans. RNA viruses are easier to spot in our oceans if you look for the right ancient gene. Using gene sequencing we can find fish that are hidden in our reefs. Visually spotting fish is helpful but can overlook sneak fish. Using environemtnal sequencing techniques way more diverse range of fish can be found.

Episode 480 - Bacteria turning methane into electricity, and corrupting corn

Young Scientists of Australia — Mon, 25 Apr 2022 22:50:42 +1000

How can bacteria turn methane directly into electricity? Why waste time producing bio gas to burn when bacteria could produce electricity directly. When bacteria take over corn, before they wreck the join they order in delivered food. Bacteria enjoy a huge feast when taking over maize, then they get to work wrecking the joint. Bacteria ends up in spots its not meant to be and redirects food away from plant cells. Redirected takeout food keeps bacteria alive as they settle into their corn host in preparation for taking over. When moving into a new house it helps to get food delivered at first, which is exactly what bacteria does.

Episode 479 - Fish that count and Spiders hearing with their webs

Young Scientists of Australia — Mon, 18 Apr 2022 17:44:02 +1000

Can fish count? What purpose does a stingray have with addition and subtraction? Why are fish and stingrays able to do basic arithmetic without a cerebral cortex? Scientists taught fish to do arithmetic with some help from Bees. What happens with you put a spider web in an anechoic chamber? How do spiders tune their webs to detect sound? Spiders webs act as powerful microphone arrays that are also cable of carrying sound across long distances. Spider webs make powerful microphone arrays that allow spiders to hear great with great fidelity.

Episode 478 - Special properties of water from molecular to drinking water to deep into the earth

Young Scientists of Australia — Mon, 11 Apr 2022 23:29:01 +1000

Water has some pretty amazing properties. We dive into some of the strange things water does from the molecular level all the way to planet scale water flows. We all know H2O but studying the way water molecules move around each other is very difficult to isolate. H2O molecules had to be taken to 0.4 Kelvin and shot with a powerful laser to shed light on the way they shake. The way H2O interacts between molecules by moving, rotating and shaking can help explain some of the weird properties. H2O has weird properties like being at its highest density at 4 degrees. Turning salt water into fresh water often involves a lot of electricity, but a new method using Ionic salts may get by with barely any heat. How can water make its way down towards the core of the earth? Water masqueraded inside minerals to migrate deep down beneath the surface of the earth.

Episode 477 - Plants reacting and defending themselves

Young Scientists of Australia — Mon, 04 Apr 2022 17:41:27 +1000

How can plants defend themselves from attack? Animals scatter when they hear an alarm cry or a predator, but how do plants defend themselves? Plants react to danger around them by detecting chemical signals. Plants emit warning through volatile chemicals and others detect these signals to raise their own defences. How do plants detect light and know where to head without eyes? How do the shape of proteins that bend a plant towards like change when exposed to different light?

Episode 476 - Capturing interstellar storms and gas

Young Scientists of Australia — Mon, 28 Mar 2022 19:34:34 +1000

Space isn't 'empty' but is often filled with gas and interstellar wind. Gas flows and moves around our universe forming stars, planets and galaxies, but how does it get there? How can you capture the complex motion of interstellar gas? What connects dragonflies with taking pictures of interstellar gas? Strapping a whole bunch of cameras together can help scientists image the faintest of light. Violent eruptions and messy eating by Neutron stars and black holes can help us understand the way interstellar gas moves in space. When a neutron star devours a planet, the remnants and gas flows can tell us a lot about star formation.

Episode 475 - Tarantula eating worms and Panda’s helpful bacteria

Young Scientists of Australia — Mon, 21 Mar 2022 15:56:59 +1000

Tarantulas are often in horror films, but they too can be subject to a mysterious invasion and slow death by nasty nematodes. "In Hollywood, you haven't really made it until you've been recognized by those in the field of parasitology" says Jeff Daniels. Why did scientists immortalize Jeff Daniels in the name of a deadly nematode. Slowly loosing control of limbs and organs is a nasty way to go out, but its how nematodes can take down a tarantula. Panda's get a lot of help from bacteria to help them survive with their limited diet. Pandas need a lot of help to survive even though they only eat bamboo. Gut bacteria helps pandas turn their bamboo into all the energy they need to build mass and fat.

Episode 474 - Fossils changing the Planet and the planet changing Fossils

Young Scientists of Australia — Mon, 14 Mar 2022 15:21:08 +1000

How can fossils change the planet and the planet change fossils? Forming fossils require specific set of circumstances. How can geological changes make the right conditions for fossils to be preserved? What happened 183 million years ago that made it possible to preserve even soft and delicate fossils? Preserving bones is comparatively easy compared to soft tissue and creatures like squid. So what has to happen to preserve these as fossils? How did fossils change the composition of rocks deep in the mantle? When life first emerged on our planet what change did it cause in the type of rocks found deep beneath the surface? life on the surface has changed the rocks we have deep in the earth.

Episode 472 - March Mammal Madness 22 - Long lasting Leaf slugs

Young Scientists of Australia — Mon, 28 Feb 2022 21:16:32 +1000

We give a rundown on the 10th annual March Mammal Madness, including the details of the brackets and an explanation on how it all works. More information about March Mammal Madness '22 can be found at the following sites:

One of the #2022MMM creatures, the Leaf Slug can go for long periods without food. Will the Leaf Slug's ability to eat and photosynthesize allow it to conquer #2022MMM? We dive into how leaf slugs manage to survive for so long without food #2022MMM. If you eat a leaf why doesn't that turn you INTO a leaf? How are Leaf Slugs managing to sneak out extra food for months after eating some algae? Forget emergency rations, Leaf Slugs can (solar) power on through long periods without food. How can Leaf Slugs avoid the Nitrogen trap and have a balanced diet for long periods without food.

Episode 471 - Extreme weather and protecting cities

Young Scientists of Australia — Mon, 21 Feb 2022 18:19:00 +1000

Ways to protect our cities as climate changes causes more extreme weather. How can we better prepare our infrastructure for damage from extreme storms. Extreme events like storm Eunice can wreck havoc on electricity networks. How can we better prepare our cities? Climate changes makes extreme weather more common so what can be done to predict the risk to key infrastructure? Urban areas can swelter in heat waves, but can urban greening help limit the impact? What benefits does urban greening provide to limit flooding and overheating in extreme weather? When an atmospheric river meets a mountain range it can create a deluge.

Episode 470 - Mysteries in our galaxy unearthed by radio telescopes

Young Scientists of Australia — Mon, 14 Feb 2022 19:08:56 +1000

Radio telescopes cover large areas and can find strange objects lurking in space. From slowly pulsing magnetars to cosmic ray filaments. Surrounding the black hole at the center of the Milky way are strange but regular filament like structures. Cosmic rays electroncs moving near the speed of light are creating regular 'gash' like filaments around the center of the Milky Way. There is a supermassive blackhole at the center of the Milky Way, but it's surrounded by even weirder things. Astronomers deal with 'transients' from slow ones like supernova to fast pulses like Pulsars...but there might be something in between. A new type of stellar object is pulsing three times an hour dumping out huge amounts of radio waves all relatively close to home.

Episode 469 - Creatures with giant mouths and giant eyes

Young Scientists of Australia — Mon, 07 Feb 2022 17:03:34 +1000

Giant mouths and giant eyes may look cute, but they give some serious advantages when eating. How do whales manage to gulp so much water to feed without drowning? Lunge feeding where whales swallow huge volumes of water is a fast way to eat but how do whales avoid drowning? Whales and humans share some special developments to stop food (or water) going down the wrong way. Would it be possible for humans to eat underwater like a whale? How do large eyes help a creature? A creature that invests in overly large eyes must have some advantage from them. A cartoony crab with huge eyes was actually a pretty fast predator.

Episode 468 - Stopping frostbite and bacteria using chemistry and physics

Young Scientists of Australia — Mon, 31 Jan 2022 22:44:21 +1000

How can we protect skin from frostbite before it happens? Scientists freeze cells in the lab all the time, so how can that be used to help prevent frostbite? When treating frostbite minutes can make a huge difference. How can we improve prevention of the worst injuries from frostbite? You've heard of sunscreen but what about frostbite cream. Antiobiotic resistance is a serious issue, but what plasma could be a secret weapon. Using plasma we can engineer antimicrobial surfaces. Plasma sintered surfaces can wipe out bacteria.

Episode 467 - Repairing throats and better implants

Young Scientists of Australia — Mon, 24 Jan 2022 17:05:47 +1000

How can we make stronger implants that don't get rejected by the body? Bioactive materials can help make implants feel more at home. Replacing a knee or a hip requires not just strength but also compatibility. A new coating method makes it easier for implants to fit in. An implant has to be strong yet flexible, friendly to cells but not bacteria - it's challenging. Your vocal chords are subject to extreme forces, so how can we design an implant to repair them? Hydro-gels can help repair damaged organs and tissue even in extreme environments like your vocal chods.

Episode 466 - Tsunamis, underwater volcanoes and magnetic fields

Young Scientists of Australia — Mon, 17 Jan 2022 16:30:20 +1000

When Tsunami's strike, every extra minute of notice can help save lives. How can scientists better predict the height and journey of a tsunami? We look at the ways scientists can use tectonic plates or magnetic fields to improve tsunami predictions. Where an earthquake occurs can make a big difference to the size of a tsunami. The shallower an earthquake in a thinner sub-ducting plate can lead to higher tsunamis. When you move a large amount of sea-water the earths magnetic field changes, just enough to detect. Like reading the vibrations in seismic waves, earth's magnetic field changes enough for you to identify a tsunami. Using magnetic fields you can measure and asses the height of a tsunami much faster.

Episode 465 - Hedgehogs to mouthwash - Strange tales of the war against bacteria

Young Scientists of Australia — Mon, 10 Jan 2022 21:14:03 +1000

From Hedgehogs to mouthwash, we check in on the arms race against bacteria. MRSA super-bugs are a super problem for humans, but some pre-date the modern era. MRSA super-bugs have been around since the Industrial revolution, at least on hedgehogs. The skin of hedgehogs is a battlefield between Fungus and Bacteria, and whoever wins, we loose. We often focus on Humans vs Bacteria, but it's actually a triple threat with Fungus. The fight Fungus vs Bacteria can lead to the development of antibiotic resistance. The mouth is the gate in the castle like defenses of the human immune system, so what defends it from bacteria attackers? If you have periodontal disease, it can make it easier for other viruses to get into your body. Keeping your mouth free of bacteria plaque can keep your defense against other infections high.

Episode 464 - Rogue Planets and glass in meteorites

Young Scientists of Australia — Mon, 03 Jan 2022 17:27:28 +1000

Rogue planets hurtling across space without a place to call home. How do we detect intergalactic nomads like Rogue planets? Just how many rogue planets are out there? Are there rogue planets lurking in our own solar system? Glass inside meteorites can help us understand early earth. How does meteorite rock differ from rock here on earth? What can we piece together about the cataclysmic events that formed glass inside meteorites? Rapidly heating then even more rapidly cooling coalesced glass inside meteorites.

Episode 463 - Unlocking former junk DNA in Rice to feed the planet

Young Scientists of Australia — Mon, 27 Dec 2021 18:10:15 +1000

How was rice turned from a wild grass into a staple crop for over 3 billion people? What secrets are lurking in the 'junk' DNA of rice that can explain it's transformation? What parts of the rice genome have been long overlooked? Can non protein coding parts of a genome help define important traits for plants and animals? Proteins aren't everything; unlocking the secrets of the rice genome. How can we boost rice yields and rice bran oil content?

Episode 462 - Fish helping make smart materials and renewable tech

Young Scientists of Australia — Mon, 20 Dec 2021 16:36:54 +1000

What can fish scales teach us about the next generation of smart materials. Why is 'scale armor' often found in video games and on fish so strong? What is special about fish scales that can help us make a new generation of smart materials for clothing and structures? What do 35 million year old fish trapped in mud have to do with wind turbines and batteries? Renewable tech relies on Rare earth metals, so where do we find them? Studying fossilized fish can help us find more sources of rare earth metals to build more renewable tech.

Episode 461 - What trees can help save a city

Young Scientists of Australia — Mon, 13 Dec 2021 17:39:59 +1000

Planting trees can help save the planet, but which trees should you plant? How do you decide what trees to plant and where to help the environment and people? Trees can help reduce pollution in the air and ground, so where are they most effective in a city? Planting urban trees can have significant public health benefits, but what trees are most effective to plant? Just what exactly is grass? How can detailed modeling and genetic testing help solve the riddle of grass classification? Are grass leaves and sheathes one thing, or is it stem and leaf like a tree?

Episode 460 - What shape is the heliosphere

Young Scientists of Australia — Mon, 06 Dec 2021 18:58:24 +1000

Just what is the heliosphere and how doe sit work? What shape is the heliosphere (spoiler alert, probably not a sphere). At the very edge of our solar system lies the boundary between our neighborhood and interstellar space. Do outside forces from interstellar space jumble up the heliosphere? Sandwiched between Space and the Earth, the Ionsphere buzzes and hums with a pulsing generator. Winds from earth can bend and shape plasma in our ionsphere to make a generator. Moving a conducting object through a magnetic field can generate electricty, and its happening right now 100km above our heads.

Episode 459 - Bees that eat meat, and Ants with a social stomach

Young Scientists of Australia — Mon, 29 Nov 2021 15:44:53 +1000

Bees seem friendly and sweet, but what about a bee that eats meat? What has to happen to allow a bee to consume meat instead of pollen. What does honey produced by meat eating bees taste like? How do meat eating bees bite into their food? How different is the stomach of a meat eating bee from it's vegetarian cousins?Forget photos of food on social networks, ants have a whole social stomach for exchanging proteins. Ants carry and exchange all sorts of fluids to help parts of the colony at the right time. Ants second stomach does not contain food but is used to help process fluids for the colony.

Episode 458 - Molecular methods to fight fungi and bacteria

Young Scientists of Australia — Mon, 22 Nov 2021 16:23:13 +1000

There's a public health crisis looming beyond the pandemic. Researchers across the world are working to stop the next public health disaster - the rise of antibiotic resistance. We rely on antibiotics to treat various disease but their effectiveness wanes as bacteria builds its resistance. How do we keep track of the changes in bacteria's resistance to antibiotics? What do bird droppings in Cambridge tell us about antibiotic resistance? Developing new antibiotics is tricky, what part of bacteria do you target? Is it better to have a simple molecule or a complex one when tackling bacteria? Bursting the bacteria cell is one way to defeat but its even better to break their building blocks. Fungal infections are growing more resistant to treatment. How can we devleop new categories of anti-fungal treatments?

Episode 457 - Not so Empty Space near Earth

Young Scientists of Australia — Mon, 15 Nov 2021 19:26:28 +1000

Space is big and vast, but whilst not densely packed like in Sci Fi, there's still so much going on around Earth's orbit. Mapping out the local neighborhood around Earth's orbit is tricky but important work. We think we have an idea about most Near Earth Asteroids but occasionally they can sneak up on is. A chip off the old block of the Moon has become one of our newest near Earth Objects. How we clean up space junk without touching it or grabbing it with a rocket? Can magnets help us handle delicate space junk? A satellite spiraling out of control is not an easy object to tame and de-orbit.

Episode 456 - Responding rapidly to bad smells

Young Scientists of Australia — Mon, 08 Nov 2021 18:37:14 +1000

How does our brain filter and process all those smells? Our brain has a lot of dedicated space for smells, but knowing which is which is tricky. How does our brain respond so quickly to bad smells? We will move out of the way of a bad smell fast. In under half a second you brain can detect and move away from a bad smell. Why are our brains hard wired to detect and react to the smell of caramel? Furaneol gives off a caramel like smell and is found in fruits and even bread. Why does our brain dedicate space to it? What is better at waking you up - a good smell or a bad smell? How do brains process smells even whens sleeping?

Episode 455 - Growing rocket fuel on Mars and greener jet fuel on earth

Young Scientists of Australia — Mon, 01 Nov 2021 15:44:26 +1000

Growing rocket fuel on the surface of Mars, and greener jet fuel here on earth. The problem with space travel is you have to take everything with you. Including fuel. Is there a way to grow your own fuel to make the load lighter on a rocket? A round trip to Mars needs billions of dollars of fuel. Is there a way we can reduce cost and energy by producing rocket fuel on the surface of Mars? How can you grow rocket fuel on mars using microbes? Would the same rocket fuel you use on Earth make sense to use on Mars? How can we clean up the aviation industry's carbon emissions? Are there alternative jet fuels that don't come at the expense of growing food? Bio-fuels are often produced at the expense of food, but are there alternatives that are win win?

Episode 454 - Evolution‘s strange journeys in crabs, snakes and lizards

Young Scientists of Australia — Mon, 25 Oct 2021 19:48:55 +1000

Why does nature continually evolve crabs? What is so good about crabs that nature just cannot stop inventing it? How can you trap a crab inside amber? What can a fossilized crab, capture din amber tell us about the complex history of crabs? Just when did crabs invade land and how did they get stuck in tree sap? How do you preserve fossil as delicate as a crab? How did lizards and snakes develop their complex teeth? Mammals weren't the only ones to evolve complex teeth with cusps. Evolution isn't necessarily a one way progression, sometimes complexity can be rolled back like in lizards. Lizards developed complex teeth to eat plants, but then some went back to their old ways.

Episode 453 - The early days of our solar system

Young Scientists of Australia — Mon, 18 Oct 2021 16:20:27 +1000

Studying the earliest days of our solar system by looking at meteorites. We don't have to travel to asteroids or dwarf planets in order to study their geology. By studying meteorites we can piece together the mystery behind the formation of our solar system. Asteroids seem to be 'missing' mantle like rock, so how can we find it by studying meteorites? Some meteorites can capture like a time capsule pieces from our early solar system. Some of this leftover bits from the early days of our solar system contain raw pieces from other stars. Sometimes in meteorites you can find matter that has traveled all the way from other stars.

Episode 452 - Eureka Prizes 21 - Fighting back against viruses

Young Scientists of Australia — Mon, 11 Oct 2021 19:13:12 +1000

We celebrate the winners of the Eureka Prizes in 2021. The top prizes in Aussie Science shows that it's possible for major science awards to not be male dominated. Are humans just the collateral damage of the war between cholera and protozoa? How does getting eaten actually make cholera stronger? We celebrate the achievements of Australian scientists helping make rotavirus vaccines more accessible for all. Producing vaccines cheaply and locally, that are easy to roll out can save half a million lives each year. Whilst vaccines for rotavirus exist already they are complex and costly. Aussie researchers are helping make it simpler and widely available.

Episode 451 - Microbes and Metals as allies and enemies

Young Scientists of Australia — Mon, 04 Oct 2021 17:02:59 +1000

Microbes and metals as enemies and allies. Metals can have superb antimicrobial properties but they're not ideal for making sheets...unless. Using a melt in your hand melt, and some copper you can make antimicrobial sheets and masks. Metals are great at fighting microbes but are challenging to make comfortable to wear. Is it possible to get a bio drive fuel cell? Bacteria can be used to clean up waste, but can they also make electricity at the same time? Cleaning up pollution and producing renewable electricity, what's not to love about the bacteria Shenwanella. With metallic tinged skin, bacteria can be boosted into a garbage eating electricity producing machine.

Episode 450 - Dating lobsters and islands under the sea

Young Scientists of Australia — Mon, 27 Sep 2021 18:22:13 +1000

Dating lobsters can be tricky and not just because they pinch. We think lobsters can live for decades or centuries, but we can't actually track their age. Just how do you find out a creatures age without dissecting them? Tracking a creatures age is tricky when they cast away alot of signs of physical growth. How can there tightly knit families spread across huge distances in the sea that are somehow connected? How do genetic islands form inside the oceans? What can chaos, larvae and Antarctica tell us about genetic diversity?

We celebrate the greatest scientific awards night, the 31st Ig Nobel Prizes. In this multi part special we find out about the history of the Ig Nobel prizes and some of the more well known examples from storied history. Who came home with the top prize this year in the Ig Nobel's? How can you navigate a crowd safely? What's the best way to model a busy train station? Does using a phone make it harder to navigate a crowd safely? Do people coordinate and work together to make through a rush hour crowd? Does a crowd self organise into lanes to navigate a busy intersection?

Episode 448 - Ig Nobel ‘21 Part 1 - Invasion of the chewing gum

Young Scientists of Australia — Mon, 13 Sep 2021 17:37:39 +1000

We celebrate the greatest scientific awards night, the 31st Ig Nobel Prizes. In this multi part special we find out about the history of the Ig Nobel prizes and some of the more well known examples from storied history. Who came home with the top prize this year in the Ig Nobel's? What's the best way to airlift a rhino? Are there NSFW ways to de-congest your nose? What can a discarded piece of chewing gum tell you about your mouth or environment? A discarded piece of gum can be a mess but also a messy battleground for bacteria. Since bacteria love invading old gum, can that be harnessed for good?

Episode 447 - Defending and recovering from floods in cities and the sea floor

Young Scientists of Australia — Mon, 06 Sep 2021 20:14:10 +1000

Extreme storms will become more common, so how can cities and the sea bed defend itself. What happens to the sea floor when there is a big storm? How long does the ecosystem on the sea floor take to recover after a large storm. What can be done to protect a coastal city from flooding in extreme weather? Knowing when to batten the hatches and protect a city in an extreme storm requires careful modelling. Venice is a beautiful city, but requires constant defense from damaging flooding and storms. Venice is protected from flooding by MOSE but is there a future where the gates are permanently closed? The complex interaction between sea level rise, Mediterranean and Adriatic seas make protecting the Venetian lagoon tricky.

Episode 446 - Brains and Guts connected in surprising ways

Young Scientists of Australia — Mon, 30 Aug 2021 17:52:34 +1000

Your brain and gut are connected in surprising ways. Inside your GI tract is a surprisingly complex nervous system. Your GI tract has it's own nervous system which is more like the spine than other organs. How does your GI tract differ from other soft hollow organs? The connection between gut microbiomes and brains is clear, but not well understood. Certain microbes can cause neurodegeneration in brains just as bad as a poor diet and no oxygen. How can we stop brains copy and pasting toxic byproducts across our brains? Proteins keep our brains in check and prevent build up of toxic byproducts, but this can be used to put the brakes on neurodegeneration.

Episode 445 - De-carbonizing Transportation and Fertilizer

Young Scientists of Australia — Mon, 23 Aug 2021 17:14:48 +1000

Can you really power a plane with enough batteries to fly across the world? How many batteries does a ship need to circumnavigate the globe? Is there an efficient way to stop relying on diesel and dirty jet fuel? How can we turn big CO2 emitters like ships and planes into CO2 negative systems? Can aviation and transport ever be carbon neutral? How can we make fertilizer without using so much energy? The Haber Bosch process helped feed the planet, but how can we replace it to save the planet?

Episode 444 - Deadly Creatures in Australia for Nat. Sci Week

Young Scientists of Australia — Mon, 16 Aug 2021 17:41:39 +1000

It's National Science Week in Australia so we celebrate with some Aussie Science. What's more Aussie than dangerous creatures? Queensland Museum researchers have found even more spiders in Brisbane. Golden Trapdoors sound like they contain treasure, but since it's Australia we're talking about, its just another scary creature. Your average Brisbane backyard may contain more types of spiders than you imagine. How did snakes evolve their deadly fangs? What came first the venom or the tooth? Why have so many different snakes evolved venom where Lizards haven't? In Australia even the plants can be deadly. We know tobaccos is dangerous, but in WA scientists have found an insect eating wild tobacco plant. Wild tobacco plants can thrive in odd places in Australia and can even chow down on Insects.

Episode 443 - Strange chemistry, ice, life and moons

Young Scientists of Australia — Mon, 09 Aug 2021 17:56:45 +1000

Moons across our solar system have rich chemistry that may harbor life. Ganymede may have more water in it's 'oceans' than Earth. The makeup of Ganymede may include layers of ice, oceans and even water vapor atmospheres. Piecing together data from Hubble, Galileo and Juno to help crack the mystery of Ganymede's atmosphere. Melting ice on Ganymede's surface could explain the odd atmosphere. Enceladus has great geysers but they contain more methane than we can explain...unless we consider biological systems. Enceladus has many mysteries beneath it's ice, but could geothermal vents help explain whats in it's geysers? Cassini did a daring flyby through Enceladus' geysers, but they were filled with many things we did not expect.

Episode 442 - Just what is a metal anyway

Young Scientists of Australia — Mon, 02 Aug 2021 17:40:02 +1000

Just what is a metal anyway? It can be hard to classify things, no matter what you do there's always exceptions to the rules. Chemists, Physicists and Astrophysicists have wildly differing opinions on what a metal is. Although there is disagreement about what makes a metal, can you find new exceptions? What needs to happen to turn water into a metal? Can pure water be made to conduct electricity without needing a Jupiter sized planet? How do you turn water into a golden, shimmering, conducting metal?

Episode 441 - Augmenting the human body to keep it safe

Young Scientists of Australia — Mon, 26 Jul 2021 18:52:55 +1000

Using technology and tools to make the human body safer. How can we use exoskeletons to keep people safe? Does using a tool like an exoskeleton automatically make a task easier? How can technology that augments bodys hinder when trying to help? How can we keep our head safer during a collision. Countless people rely on bicycles for safe and green transport, but how do we make it safer? Bicycle helmets are a simple tool for helping save lives, but can they be made even safer with new materials?

Episode 440 - Turning off plants with a switch of a light

Young Scientists of Australia — Mon, 19 Jul 2021 17:55:00 +1000

Turning off plants with a switch of a light. How can optogenetics be used to turn off photosynthesis. Stomata cells help a plant from feasting too much in times of famine. Stomata cells regulate how much photosynthesis plants undertake, but can they be regulated with light? How can Yeast be used to help plants fight back against fungus. Fungal infections can devastate crops and plants, but can we avoid dangerous fungicides? How can we protect plants from, fungi without damaging the environment? Can yeast grown proteins help stop fungal infections without killing all fungi?

Episode 439 - The journey of humanity and its closet cousins

Young Scientists of Australia — Mon, 12 Jul 2021 17:28:49 +1000

What separates Homo Sapiens from our closest cousins? How do we piece together the journey of Homo Sapiens across the world? Neanderthals were capable of much more than what stereotypes suggest. How did Neanderthals produce complex art? How did Neanderthals and Homo Sapiens intermix? Was there a linking population that helped spread Homo Sapiens genes into Neanderthals long before mass migration? Neanderthals are often thought of as Europe based, but was there a larger progenitor population in the Levant?

Episode 438 - Super fast and dense White Dwarfs and odd Supernova

Young Scientists of Australia — Mon, 05 Jul 2021 17:41:57 +1000

What happens at the end of a star's life if it doesn't go out with a bang? White dwarfs are the end stage for 97% of stars, but can they still go 'nova? What happens if two white dwarf stars merge together? Rotating once every 7 minutes with a magnetic field billions times stronger than the Sun, super dense white dwarfs break all the records. There are many types of supernova, but which one happened at the Crab Nebula in 1054? What happens if a star isn't quite heavy enough to have an iron core supernova? Electrons are so tiny compared to a supergiant star, but if they're taken away it can lead to a supernova.

Episode 437 - Dark Fish hiding in the ocean depths

Young Scientists of Australia — Mon, 28 Jun 2021 19:49:56 +1000

Squeezing and grinding to create next generation materials from humble beginnings. Changing magnetic field by changing shape could open the door for more efficient computers. Magnetostriction causes that 'hum' you hear from electronics but it can be harnessed for good. Large electrical devices like transformers or fluorescent tubes shape influences their magnetic field. The next generation of computers may harness the way magnetic fields and physical shape can be linked. Forget rare earth metals, there is a more efficient way to make high powered computer chips out of humble iron and gallium. Luminescent polymers can be found in fancy OLED screens but are complex to produce. How can you make fancy luminescent polymers from generic polymers? By grinding them. A unique way of grinding and rolling basic generic polymers could create powerful luminescent polymers for use in high end screens, lasers and bioimaging.

Episode 435 - Cold war secrets and reanimating frozen life

Young Scientists of Australia — Mon, 14 Jun 2021 20:06:09 +1000

Cold war secrets buried deep in the ice and forgotten, plus reanimating frozen life from Siberia. How could some frozen dirt, forgotten in a freezer for decades help us understand a future of rising sea levels? Greenland's name was a marketing stunt by Erik the Red, but it was once truly covered in greenery. Although Greenland is so close to the North Pole, all it's thick sheets of ice have completely melted (geologically) recently. How did scientists reanimate ancient animals buried in the Siberian Tundra? Rotifers can live in some unusual places, but they can also survive being frozen and brought back to life. Ancient animals have been 'unfrozen' and brought back to life though they are very small.

Episode 434 - Parasites and Symbiotic relationships

Young Scientists of Australia — Mon, 07 Jun 2021 20:22:08 +1000

Insects and plants are locked into an arms race until something breaks the stalemate. How can a tag team attack of bacteria and insect larvae help crush through a leaf's defenses? WOrkign together as a team, larvae and bacteria can make a tasty meal out of a leaf. Plants can fight back against insets, so insects need to call out for help. A parasitic infection is bad for the host, but some ants gain an odd boost. How are tapeworms boosting the life expectancy of ants? When an ant gets infected with parasites, it's colony mates care for it boosting it's lifespan.

Episode 433 - Prioritizing memories and filtering noise

Young Scientists of Australia — Mon, 31 May 2021 17:34:42 +1000

How does your brain decide what's important to remember? You're constantly bombarded with info so how does your brain filter it all? Do memories change over time? Do certain details stand out more in our memories over time? What details can get lost in our memories over time? How does you brain know if it's worth 'saving' that picture you've seen. How does your brain filter out and only store the important stuff.

Episode 432 - Using sound and magnetism to navigate the world

Young Scientists of Australia — Mon, 24 May 2021 17:44:21 +1000

How do animals use different senses to navigate the world? Can sharks detect magnetic fields? How do sharks travel 20,000km so precisely? Can sharks use the Earth's magnetic field to navigate? What creatures use magnetism and how do they do it? Bats use echolocation, but what if the speed of sound changes? What if everything moved at 1.25 x speed? How can bats adapt to changes in the speed of sound?

Episode 431 - Super stellar collisions and super computers

Young Scientists of Australia — Mon, 17 May 2021 17:50:03 +1000

Space is really big, but when a collision happens it's incredibly complicated. Studying and predicting collisions between stars is hard even for super computers. How can you speed up the modelling of stellar collisions? A neutron star and a black hole colliding may not be as rare as you think. The collision of two heavyweights could give us the data we need to crack a century old question. The merger of a black hole and a neutron star gives off tremendous amounts of energy and may be more common than we thought. By 2030 we should have enough data captured on LIGO and other instruments to solve Hubble's dilema.

Episode 430 - Using Corn to clean water, and new wind turbine designs

Young Scientists of Australia — Mon, 10 May 2021 16:53:58 +1000

Clever engineering can turn waste products into planet cleaning tools. Corn is America's biggest crop, but it's incredibly wasteful. Corn waste can be given a second life as activated carbon to help clean water. Corn waste makes for an efficient water when it's turned into activated charcoal. Wind turbines have to be carefully placed and located to maximise their efficiency. When designing a wind farm, the location and style of the turbine can greatly impact generation. Which design is better for wind turbines; vertical or horizontal? Vertical wind turbines aren't as common, but they can work together to boost efficiency.

Episode 429 - Volcanic ash in our oceans and rafting in the air

Young Scientists of Australia — Mon, 03 May 2021 20:21:42 +1000

Volcanic eruptions are incredibly powerful but not well understood. When a volcano erupts it can spread ash far and wide both in the ocean and in the air. What happens when a volcano erupts underwater? How much energy does an underwater volcano unleash? Where does all the energy in an underwater volcanic eruption go? Is it possible for volcanic ash to form and spread underwater? Just like jetstream currents in the air, volcanic ash can be carried far and wide in underwater eruptions. Volcanic ash can get held up by smaller particles, to raft long distances.

Episode 428 - Lightning and Early life on earth

Young Scientists of Australia — Mon, 26 Apr 2021 17:17:10 +1000

What kicked off early life on earth? Organic chemistry and early life need the right minerals to be present and accessible. What helped unlock early minerals on earth like phosphorous to kick start life? Lightning strikes seem rare, but they're much more frequent than meteorites. Early life on Earth could have been helped along through lightning strikes and meteorites. DNA, RNA and Proteins are locked in a complex dance, but which came first. DNA can't replicate without the help of protein and RNA, so how did we develop DNA in the first place? Is it possible for RNA to replicate on it's own?

Episode 427 - RNA protecting your brain

Young Scientists of Australia — Mon, 19 Apr 2021 17:24:32 +1000

How does RNA work to protect your brain and keep it safe after a traumatic event? Micro RNA can play an important role in healthy brain development. Without key micro RNA, the development of the brain can run out of control. Without key microRNA, your can develop neurodevelopmental disorders. Without oxygen your neurons starve, so how can you protect them? How can you use mRNA to make neurons more resilient and recover after a lack of oxygen? Getting proteins across the blood brain barrier is tricky, so can they be snuck in via mRNA? Using mRNA, you can produce proteins to add brain recovery right where they're needed most.

Episode 426 - Tackling waste water and antibiotic resistance together

Young Scientists of Australia — Mon, 12 Apr 2021 17:03:27 +1000

Hydrogen fuel promises a cleaner future, but the methods to make it are often dirty. A new approach recycles and treats waste water with sunlight to efficiently produce hydrogen. A new electrolysis approach turns waste antibiotics into hydrogen fuel cells. Removing antibiotics and other pharmaceuticals from waster water can be tricky, but a new technique turns that into green energy. Aquaculture is growing rapidly, but it is leading to antimicrobial resistance? What contributes more to antimicrobial resistance - fish farms or waste water? Incorrectly managed waster water can lead to superbugs.

Episode 425 - Tiny creatures with a huge impact on our oceans

Young Scientists of Australia — Mon, 05 Apr 2021 14:47:40 +1000

Can you find fresh water in the middle of the ocean? What happens when a geyser of fresh water erupts from the sea floor into the ocean? A sudden freshwater spring can radically change the ocean floor. How do plankton shells and coral help us monitor a changing climate? Life in the oceans can help sequester carbon. We can track the way the climate has changed in the past by studying strontium isotopes in seawater. Changing climates can impact life in shallow and deep water, which can lead to changes in the carbon cycle. Tiny creatures like copepods can have a huge impact on our ocean food web. How do tiny creatures like copepods gather in ephemeral ocean zephyrs. Tiny vortexs can act as a gathering place for tiny but important sea creatures.

Episode 424 - Hunting for atmospheres on other planets

Young Scientists of Australia — Mon, 29 Mar 2021 15:26:03 +1000

Mars was once covered with water, so where did all the water on Mars go? What happened to the water in the Martian atmosphere? Why isn't there an abundance of heavy water in the Martian atmosphere? Water can get trapped inside rocks and minerals without volcanoes to cycle them. Volcanoes and tectonics help sequester, cycle and release water, so what happens on a planet without them? How can we hunt for signs of water atmospheres on exoplanets? On hot rocky exoplanets with oceans of magma, what happens to their hydrogen rich atmospheres? An atmosphere of of hydrogen can slowly turn and change into water with the help of a magma ocean.

Episode 423 - Humans vs Bacteria on earth and in space

Young Scientists of Australia — Mon, 22 Mar 2021 13:47:58 +1000

Space is hard, things are different there which means something simple as salmonella becomes much more challenging. The rules of bacterial infection and response change once you're in space. How does your body respond to bacterial infection in microgravity environments? Getting sick in space may be worse than on earth. The human microbiome is incredible diverse and not well understood. Your gut contains 100,000s of bacteria groups, virus and other things. A large global study of gut microbiome has revealed thousands of new virus and bacteria types.

Episode 422 - Squid blending into starlight with Bio-luminescent bacteria

Young Scientists of Australia — Mon, 15 Mar 2021 16:13:01 +1000

Squid can change colours, reflect light and blend in with their surroundings. How does the changing colours on squid skin work? What proteins and structures enable squid skin to reflect and amplify varying light? Squid can blend themselves into the starlight with the aid of bio-luminescence. The symbiotic relationship between bacteria and squid starts right after birth, and helps them shine to avoid predators and catch prey. A baby squid may not start out bioluminescent but a rapid spread of the right bacteria turns on the lights.

Episode 416 - Sourdough starters and less allergens in wheat and peanuts

Young Scientists of Australia — Mon, 01 Feb 2021 16:16:57 +1000

Sourdough baking has rising to become a global hobby, but how diverse are they? Each sourdough starter is a tiny ecosystem, and a global study shows how diverse they are. Scientists analysed 500 sourdough from across the world to find out what makes the best loaf. Baking is about carefully cultivating a microbiome. What can be done to make wheat and peanuts less dangerous for people with allergies? Can you make wheat and peanuts that are better for allergies?

Episode 415 - Greener ways to make Hydrogen and Ammonia

Young Scientists of Australia — Mon, 25 Jan 2021 15:17:55 +1000

You've probably heard about the wonders of a Hydrogen economy, but how can we make it better for the environment. Synthesizing Ammonia helped feed the planet, but at a huge environmental cost. How can we produce Ammonia without harming the environment? Production of ammonia (and fertilizer) has a huge carbon footprint. How can we clean it up? Hydrogen fuel cells could help decarbonize our economy, but how do we produce it cleanly? Electrolysis can separate hydrogen from water, but how can we do it more efficiently?

Episode 414 - The active life and dramatic death of galaxies

Young Scientists of Australia — Mon, 18 Jan 2021 17:37:19 +1000

Can a galaxy really die? What would that even look like? We know that stars can erupt into supernova, form black holes or fade away but what happens to old galaxies? What happens to a galaxy when it looses all it's fuel for growing new stars? Which galaxies are the most active and pulsing with light? Active galaxies often shine vibrantly from their core, but what causes periodic bursts of energy. NASA Goddarrd researchers have discovered the 'Old Faithful' of Galaxies.

Episode 413 - Detecting gene doping in sport, and the strange air of gyms

Young Scientists of Australia — Mon, 11 Jan 2021 15:04:12 +1000

You've probably heard of CRISPR, but what does it mean for the world of professional sports? How could gene-doping be detected by sports administrators? Could you tell if someone had used CRISPR to 'dope' their performance? WADA considers gene editing a form of doping, but how can you detect it? What happens when you mix sweat, gym equipment and cleaning products? When you exercise you release a 3-5 times the amount of chemicals than a sedentary person. What happens to the mix of sweat, amino acids and cleaning products in the air of a gym?

Episode 412 - Magnetic Glues and Chemical gears

Young Scientists of Australia — Mon, 04 Jan 2021 15:29:32 +1000

Waiting for glue to cure can take a long time, but can magnets speed it up? We use epoxy to glue together so much of the modern world, but it takes a lot of energy to cure it. Is there a way to make epoxy glues more 'energy efficient' with magnets? Magnetically activate glues can literally stick your shoes together. Gears are one of the most fundamental mechanical elements, can we get chemicals to form gears themselves. A 1mm thick sheet with some chemicals and you can get gears to form themselves. Small gear trains and mechanical motion can power soft and flexible machines.

Young Scientists of Australia — Mon, 07 Dec 2020 16:14:11 +1000

Life underneath the sea floor at the deepest parts of the ocean. How can life survive in deep sea with no light and at incredible temperatures? Have you ever thought about life beneath the beneath the sea? How can life survive in soil hotter than boiling water? If a tree feels out of place, it's microbes on leaves tend to blend in with the crowd. What happens to the microbes on the iconic maple leaves as the trees go further north? Feel like a fish out of water, or a maple amongst conifers? Maybe its time to blend in. How can we use plant based compounds to help keep plants safe from bacterial infection?

Episode 407 - Random generating DNA and random mouse movements

Young Scientists of Australia — Mon, 30 Nov 2020 15:36:42 +1000

Random numbers are incredibly important for our digital economy, so how do we generate them? What is the best way to make a random number: roll a dice, lava lamp, guess, DNA? What connects lava lamps, e-commerce and synthetic DNA? How can we better generate random numbers using synthesized DNA. How do your mouse movements reveal about your decision making process. Do mouse movements help us identify risk takers or keen deliberators. Whether you know it or not, your mouse moving may be part of your decision making process.

Episode 406 - Lifting mountains out of the ground...with rain

Young Scientists of Australia — Mon, 23 Nov 2020 17:19:19 +1000

Lifting mountains out of the ground with...rain? How do mountain ranges form is a surprisingly difficult question to answer. Complex equations with lots of inputs are tricky to model and solve, but can help us understand the way mountains form. Rain, cosmic particles, sand and the Himalayas can help us understand how mountains form. It's hard to picture, but mountains actually float on the molten rock of the mantle. Make them lighter and they'll rise. Do rapid climate swings change mountains, or do mountains change the climate? The answer is tricky.

Episode 405 - Studying Supernova, pollution and air quality with trees

Young Scientists of Australia — Mon, 16 Nov 2020 15:05:20 +1000

Studying supernova and air quality with the help of trees. Supernova are some of the most devastating events in the universe, but what is their connection to trees? By studying tree rings we can help piece together the final days of stars. Supernova can cause large spikes in radiation that can be detected in tree rings. Trees do a lot for us but they can also help us track air quality simply and cheaply. Magnets and pine needles can helps us understand air quality. Air quality monitoring can be a matter of running a magnet over some leaves.

Episode 404 - Ants , Acid, and Yeast that grow acid

Young Scientists of Australia — Mon, 09 Nov 2020 17:45:03 +1000

Ants, acid and yeast that can grow their own acid. Ants use formic acid to keep their colony safe inside and out. By ingesting formic acid, Ants are able to ward off dangerous pathogens. Passing food with your mouth isn't very socially distant, but ants eat acid to make it safe. How can yeast be used to 'grow' materials needed to make perfume and dyes? Succinic acid is a useful chemical precursor, but its possible to grow yeast that are able yo produce on scale as a by product. Finding just the right genes with CRISPR and super computers can turn yeast into a chemical production powerhouse.

Episode 403 - Taking pollutants out of our water, factories and environment

Young Scientists of Australia — Mon, 02 Nov 2020 17:47:09 +1000

How can we take pollutants easily out of our water, factories and environment? PFAS contamination is difficult to clear up, but a new method could attract, trap and destroy it with electrodes. PFAS can be found in many things, but taking it out of an area has often been very difficult. Using a tunenable electrode, in 3 hours you could extract and destroy PFAS in contaminated water. A combined clay and glass filter could neatly trap and extract CO2 from a gassy mixture. industrial processes often produce CO2 amongst other gases, but how can you quickly only separate out that CO2, reuse it and prevent it from being emitted? Lead in drinking water is a serious issue,but understanding the amount of exposure is difficult. A new method for analysing lead in drinking water tips acid onto 'filled' filters.

We find out more about two more Ig Nobel prizes, for Accoustics and Entomology. Spiders aren't insects, but they're pretty similar. So why do so many entomologists fear spiders? Lots of legs, moves suddenly, weird shape, are fine for entomologists but add 2 extra legs and it's right out. Extra legs are a deal breaker for entomologists with a fear of spiders. Helium, Alligators in a tank, and resonant frequencies won this group a Ig Nobel prize. You've heard of beard song, but what about Alligator on helium song?

Episode 395 - Learning from unusual plants

Young Scientists of Australia — Mon, 07 Sep 2020 18:32:43 +1000

Plants are incredibly important for a healthy planet and a well fed population. How can we improve our plants by learning from some unusual ones? You normally picture a plant with lots of leaves, but some only grow one lonely leaf. Deep in limestone caves of South East Asia grows a plant with only ever one giant leaf. How can a plant survive with just one leaf and why does it continue to grow in size? What can we learn by studying the root systems of different plants?

Episode 394 - Travelling through time with telescopes

Young Scientists of Australia — Mon, 31 Aug 2020 18:14:08 +1000

Telescopes can help us travel back in time to the early universe. We can watch galaxies form, the universe have a makeover and giant black holes appear. Using different telescopes we can learn about the cosmic dawn and the cosmic noon. The early universe was hazy and hard for light to travel far. What gave the early universe a makeover to allow starlight to travel? What fed the super hungry super massive black-holes of the early universe? Where did the early black holes find enough food to make them swell to massive sizes? What can we learn from the cosmic noon when most of the stars in the universe were formed?

Episode 390 - Cool fabrics, melting ice and recycling e-waste

Young Scientists of Australia — Mon, 03 Aug 2020 18:31:26 +1000

From cool fabrics, to melting ice and recycling e-waste. How can a fabric let air through, but keep water out? Clothing that is breathable, water resistant and thermally efficient hits the sweet spot of a super fabric. Making clothes more efficient at cooling but also self cleaning can reduce our reliance on air conditioning. Using electricity and some polymers we can spin up some new cool clothing fabrics. Melting ice in your frozen over freezer can be made easier with biphillic materials. Materials that both hate and love water at the same time, can help melt ice and make heater exchangers more efficient. Recycling e-waste can be tricky, but what if we could use the by-products to make new, stronger coatings for steel? Turning e-waste into a steel boosting coating.

Episode 384 - Plants regenerating and fighting off invaders

Young Scientists of Australia — Mon, 22 Jun 2020 18:02:35 +1000

How do plants manage to recover from damage or fungal attacks? What happens when you shoot a laser at some cress? Studying the way plants respond to damage helps us understand their regeneration methods. Plant cells can regenerate to recover from damage, but what controls this process? Fighting off a fungal invasion means an arms race between plants and fungus. Plants like cabbage use a special mustard oil bomb to fight back against fungal invaders. Fungal invaders like white mold can render even the most sophisticate plant defences useless.

Episode 359 - Life surviving on freezing planets, faint suns and meteorites

Young Scientists of Australia — Mon, 30 Dec 2019 21:45:52 +1000

What can bacteria from an iron ore rich lake tell us about life on early earth? Have scientists finally solved a Carl Sagan paradox about life on early earth? When the earth was young, so was the sun, and that meant less light and heat. How did early life on earth survive if there was not enough sunlight to keep it warm? How did iron ore eating and secreting bacteria help lead to widespread life on our planet? How did micro organisms get enough oxygen to survive when the entire planet was frozen over? What can iron ore deposits tell us about life surviving when the entire planet was frozen over? Can life survive on a meteorite, the answer is surprising. How can a microbe be more suited to life on a meteorite than on earth?

Episode 356 - Responding to signs of danger

Young Scientists of Australia — Mon, 09 Dec 2019 15:10:04 +1000

How do animals communicate information about danger? When a threat is detected by one animal, how do they pass it along to others? Does empathy play a role in how a create responds to a threat? Does the reaction of others around you change your response to threats? What chemical causes you to freeze in response to danger? How does serotonin cause deer in the headlights moments? What's the link between serotonin and slowing down in response to danger?

Episode 355 - Satellites keeping us safe on the ground

Young Scientists of Australia — Mon, 02 Dec 2019 16:09:10 +1000

Satellites can help save lives down on earth, by helping us better respond in disasters. When a flood, tsunami or other disaster strikes, satellites can help emergency responders get where they need to be as fast as possible. Satellites can track floods in near real time and help shave minutes of disaster response times. Finding your way in a flood or fire can be tricky, but satellites can help direct emergency responders. Satellites can help track critical infrastructure like bridges or roads as they age. When a bridge fails it can be a tragedy, but satellites can help give an early warning. When we dig big tunnels we can disturb structures and buildings, so how can we use satellites to avoid a disaster.

Episode 354 - Safer pacemakers and mini machines inside our cells

Young Scientists of Australia — Mon, 25 Nov 2019 16:41:37 +1000

Our bodies are filled with molecular and cellular machines, pumping, spinning and moving. How do tiny single molecules pump sodium ions across a cell? What is the connection between a single molecule pump and cells producing electricity? How can a single molecule pump be more efficient than our modern ones? How do we make pacemakers safer? Overtime a pacemaker grows to become part of the heart fibre. How do we make pacemakers less likely to be overgrown and easier to replace?

Episode 353 - Mysteries of plants, from using rare metals to boosting photosynthesis

Young Scientists of Australia — Mon, 18 Nov 2019 16:39:07 +1000

Plants play an important role in our environment, yet there is still so much more to understand. We often think of nature as a zero sum game, but older and younger plants can collaborate. When surviving in a harsh environment, the best results occur when old and young plants grow together. Photosynthesis seems simple, but understanding the intricacies of the mechanisms can help us boost crop yields. Regulating the amount of photosynthesis can help plants survive or thrive in changing climates. How do boreal forests help capture nitrogen from the air? What does an odd metal have to do with forests in Canada storing nitrogen?

Episode 352 - Figuring out where sound comes from and perceiving pitch

Young Scientists of Australia — Mon, 11 Nov 2019 15:49:45 +1000

This week we look at the way our brains process sound, music, pitch and rhythm. How does our brain figure out where a sound is coming from? Do our eyes and ears process distance and location in a similar way? How does our brain discern differences in stimuli? What can we learn about pitch and rhythm from studying a remote Bolivian tribe? Is there a biological limit to our perception of sounds? Is our ability to perceive rhythm, chords and pitch cultural or biological?

Episode 351 - A new dwarf planet and what makes an exoplanet habitable

Young Scientists of Australia — Mon, 04 Nov 2019 16:46:15 +1000

What makes a dwarf planet not a planet? What are the rules governing the word planet? Just how many dwarf planets are out there in our solar system? How can we use telescopes and modelling to add or subtract a dwarf planet from that list? We've talked about Goldilocks zone exoplanets, but what about their ability to withstand space weather? What role does a star's magnetic field play in protecting a planet from damaging radiation? Does space weather need to be added to the exoplanet Goldilocks zone?

Episode 350 - Developing, tracking, recycling new materials

Young Scientists of Australia — Mon, 28 Oct 2019 21:26:51 +1000

Smart phones, computers, televisions and even children's toys are part of what makes our modern world so exciting. But these often rely on plastics and rare earth metals which are hard to recycle. Are there efficient ways to capture all those rare earth metals? How are rare earth metals in old phones recycled today, and can we make it better? Knowing which bin to put plastic in is difficult, so what if there was a more universal way to recycle plastics? How does turning plastic into a gas with the help of steam help create a circular plastic economy? How can some steam power help crack plastics back into their most basic forms? Is it possible to recycle plastics without to build whole new plastic refineries? Regulation is often playing catch up to making materials safe. Are the latest generation of 'safe' fire retardants any safer than those that came before?

Episode 349 - Domesticating fungus for our food

Young Scientists of Australia — Mon, 21 Oct 2019 16:35:41 +1000

Humans have been using micro-organisms like fungus and bacteria to help improve our food for millennia. Can we tame new wild species of fungus to help create new types of our favourite foods like cheese? Penicillin is mostly known for antibiotics but it also helps give Camembert its particular taste. What causes cheese to rapidly tame wild strains of fungus? We are not the only ones who use microbes to help our food. Ants help stop disease from destroying plants by spreading their own antibiotics. Ant base antibiotics help stop plant pathogens. Sometimes bacteria don't fight against each other but rather team up and work together. Survival of kindest rules for bacteria, which helps different strains work together to survive.

Episode 347 - Capturing carbon with better farms and forests

Young Scientists of Australia — Mon, 07 Oct 2019 16:00:04 +1000

Capturing carbon is important for helping offset CO2 emissions and tackling climate changes. Farming has an important role to play in improving CO2 sequestration with the use of cover crops and compost. Forests are important carbon sinks too, but they are at risk releasing a lot of the trapped carbon if care is not taken to stop invasive species. Plus fertilisers have helped feed the planet but can leech out nitrogen into the environment, so how do we better manage and improve the nitrogen cycle.

Episode 346 - Can washing machines help stop microplastics in oceans and make hospitals safer

Young Scientists of Australia — Mon, 30 Sep 2019 21:36:08 +1000

Washing machines can save a lot of time and help clean up mess, but they can also harm our health and environment. Which washing process is better for the environment - full an fast or empty and delicate? How do washing machines help fill our oceans with microplastics? What can be done to help stop washing machines contributing to the microplastics in our waterways? Which washing setting is best for your health? Cold and clean or warm and soapy? How did a normal washing machine cause havoc in a hospital? How can you multi-drug resistant pathogens spread through a washing machine?

Episode 345 - Overactive immune brain cells and brain cells failing to eat themselves

Young Scientists of Australia — Mon, 23 Sep 2019 20:29:49 +1000

Is it possible to stop Alzheimer's in it's tracks? How does the formation of plaques on your brain cells lead to Alzheimer's. Does the your brain immune cells fighting back against plaques lead to Alzheimers? Amino acids in the brain tying themselves into knots, can lead to super strong sealed zippers forming which dry out proteins, damage neurons and eventually can lead to diseases like Alzheimer's. An enzyme missing a repair or two over 60 years can lead to build up of kinked amino acids chains which can lead to neuron-degenerative diseases. What causes a cell to eat itself? Well its actually a pretty healthy thing to do. If a brain cell doesn't eat itself at the right time, well it can lead to a whole bunch of diseases.

Episode 344 - Colliding galaxies, stellar foundires and the emptiness of space

Young Scientists of Australia — Mon, 16 Sep 2019 19:38:11 +1000

We look at galactic events, where galaxies collide, stars form and emptiness of space. Space is so unfathomably huge, but its still possible for galaxies to collide. The Milky Way was formed through one of this violent collisions over 10 billion years ago. Space seems empty but there are sections of space that are emptier than others, the great Local Void around the Local group. Stars forming in galaxies rely on gas clouds, but what does it take to form a star? What do you need to really make a good nursery for stars?

Episode 343 - The circadian rhythm of plants, and fighting back against fungus

Young Scientists of Australia — Mon, 09 Sep 2019 17:57:46 +1000

Growing enough food to feed the planet is a challenge that will only get harder as the climate changes. So how do farmers and scientists work together to make crops more sustainable, more resilient to disease, and use less herbicides? With genetic engineering, one of the worlds most important crops, rice, can be made even tougher. Using a two type bait gene, rice can be engineered to fight off fungus like rice blast. If you have to spray with herbicides, when should you do it? Well you need to pay attention to the circadian rhythm of the plants.

Episode 342 - Better chemistry and physics in everyday objects

Young Scientists of Australia — Mon, 02 Sep 2019 18:13:07 +1000

How can we use physics and chemistry to help improve our everyday objects? Melting ice is very important for airplanes and air-conditioners. How can you melt unwanted on objects ice more efficiently? Ice on an airplane wing can be dangerous, so how do we melt it more efficiently. Flame retardants are important to stop fire spreading, but how do we make them safer and environmentally friendly? Flame retardants often rely on petroleum which are not environmental friendly. How can we stop flame retardants leeching into the environment or into our households? How do you get white paint without relying on environmentally intensive additives. What can beetles and recycle plastic teach us about making whiter paint.

Episode 341 - Forming, Saving and preserving new memories

Young Scientists of Australia — Mon, 26 Aug 2019 16:11:55 +1000

Your brain uses proteins synthesis and redundancy to help form and keep memories. Intricate biochemistry helps your neurons connect to each other to form new memories. Forming new memories is a sticky situation. Keeping them stuck together over time in a long lasting memory relies on protein synthesis. Its important not just to have strong connections between neurons to form memories, you also need spares. By having redundancy and backups it means that you can still remember a key memory if one of those connections fails.

Episode 340 - Insects revolutionizing agriculture

Young Scientists of Australia — Mon, 19 Aug 2019 18:49:57 +1000

Insects are often thought of as the enemy of farmers, but they can help improve farming. From helpful worm pheromones, to farming crickets and hungry termites. Worms can help boost the resilience of crops like wheat, corn and maize to common threats. Worm pheromones help plants fight back against bacteria, viral and fungal invaders. If insects are the super food of the future, how do you successfully farm them on a large scale? What nutrient rich feed do insect farms need to give their herds? If you are growing crickets and locusts do they need different food? What food is best for termites and how can they be used to help better manage forest?

Episode 339 - Australian Science - life on gold, in the oceans and in deadly gas

Young Scientists of Australia — Mon, 12 Aug 2019 17:20:40 +1000

To celebrate National Science Week in Australia we are turning our attention to Australian research on the global scale. This week it means tales from microbiology. Stories of how life can survive or sometimes thrive in strange situations. Whether it be Fungi that eat gold, or bacteria chewing deadly gas, microbiology is always full of surprises. How do the tiniest parts of the food-web of our oceans hunt for food in the swirling of stagnant currents of the ocean? How do bacteria turn deadly gas into a food source? Is the secret to tuberculosis's resistance its ability to survive off deadly gas? How do bacteria turn carbon monoxide and hydrogen into something palatable?

Episode 338 - Exoplanets boiling and stretching, Goldilocks and Supernova

Young Scientists of Australia — Mon, 05 Aug 2019 19:54:51 +1000

Boiling planets being stretched and squished. Tiny white dwarf stars going supernova. Goldilocks planets potentially with liquid water. Exoplanet hunting is now a lot easier with missions like TESS and veterans like Hubble. We look at some special cases, and how searching for 1 planet can uncover loads more. Sometimes planets are lurking in old observatory data, we just need to know where to look. Too hot, too cold, GJ357 potentially has a planet that's just right with liquid water. What causes a White Dwarf to go supernova? It needs more than itself to kickstart it into a Type 1a nova...so where does the extra boost come from? Devouring another planet? Or another star?

Lagrange Point Episode 337 - Stopping deforestation, saving species and conservation

Young Scientists of Australia — Mon, 29 Jul 2019 15:10:28 +1000

As the climate changes different species are at risk. Some will thrive and others will struggle, so how do we target conservation efforts to better protect at risk species? Deforestation is a big issue in developing countries, but is there a win-win for the population and the planet? When sea levels rise, we think about flooding and erosion, but not what will happen to the forests and birds who live in them. Trees in the city live fast and die young, which means we need a whole new set of forest management techniques.

Episode 336 - Life frozen in time inside extreme ice

Young Scientists of Australia — Mon, 22 Jul 2019 15:15:16 +1000

Ice can be refreshing and cooling, but it can also be used to preserve life. Sometimes for strangely long periods of time. So just how do you make extreme forms of ice? From 'warm ice that doesn't ruin your frozen food, to controlled ice that helps planes fly. Sometimes you can even use a diamond to make some super controlled ice. Ice can harbour life even in some extreme conditions like the frozen and UV radiated Andes. Buried in Alaska is a bacterial community frozen in time. For 50,000 years bacteria have been thriving beneath layers of frozen tundra.

Episode 335 - Oceans, ocean size algae, deserts and fresh water in strange places

Young Scientists of Australia — Sun, 14 Jul 2019 12:13:04 +1000

Water, water everywhere but not a drop to drink or nutrient for that matter. The Ocean can sometimes be a inhospitable place with barely any nutrients to survive off. Other times it can be home to large ocean spanning algae blooms. The oceans from the Pacific to the Atlantic can hold lots of secrets (even fresh water) beneath the surface. This week we look at 3 different papers which outline strange parts of the ocean, from large algae blooms to hidden aquifers.

Lagrange Point Episode 334 - Hidden in empty space

7/7/2019

0 Comments

Space seems so incredibly vast and empty, but there is a lot hidden inside that seemingly empty void. From fungal spores to charged bucky balls. Radiation in space seeps everywhere and makes long term space travel dangerous for humans, but fungal spores cope just fine. Radiation can also cause beautiful light shows like the aurora but can make light tough for astronauts. How can we use social media to track the beautiful aurora light shows? How do we clean a space ship or space station?

Episode 333 - Saving which bees and where

Young Scientists of Australia — Sun, 30 Jun 2019 17:35:17 +1000

Saving the bees has gotten widespread understanding, but it is more nuanced than a simple sound bite. Which bees are in danger and where? How many bee species are out there and are under threat? Can domesticated bees spread disease to wild populations? How do wild flowers help feed bees but also spread disease? Can different types of crop cycles help both wild and domesticated bees thrive? We know of colony collapse disorder and pesticides, but what other threats are out there to bee populations? Does the urban sprawl play a role in destabilising the gender balance of the bee populations? Why do bee populations drop off as you approach the city?

Episode 332 - Affordable, smart and helpful prosthetics

Young Scientists of Australia — Mon, 24 Jun 2019 22:38:23 +1000

Getting a prosthetic limb to feel natural and comfortable without spending a fortune is incredibly difficult. Plus the human body (and prosthetics) change over time. So how can you make a prosthetic better match it's user? We look at three stories of adaptive prosthetics and finding ways to make use of new technology to help improve lives. From building an elaborate treadmill contraption to hearing through your fingers.

When you stumble your brain goes into overdrive to keep you standing, but what exactly does it do?

Affordable and comfortably fitting prosthetic limbs are especially important for children who grow out of them quickly. How can we make them more responsive?

Hearing words clearly in a noisy environment is especially hard on those with hearing aids. But can your fingers help out?

Vanderbilt University researchers built an elaborate treadmill to trip people, with the goal of helping advance prosthetic research.

Using 3D scanning, printing and embedded sensors, researchers are making prosthetic better matched to their users.

People often say look with your eyes not your fingers, but can you use your fingers to hear as well?

Embedding sensors into 3D printed prosthetics can help adapt the design to better suit the actual wear and tear from the body.

Using an elaborate tripping contraption on a treadmill, Vanderbilt university researchers hope to stop prosthetic leg users falling over.

Episode 331 - Making modern technology less energy intensive

Young Scientists of Australia — Mon, 17 Jun 2019 17:21:11 +1000

Our modern world relies on energy, and some of it produce a lot of carbon dioxide. How can we make everything from air travel to wearable tech be less carbon intensive? Is there a way to make jet fuel or power ships that is carbon neutral? Just how much energy do crypto currency burn up? What is the impact of all this Bitcoin speculation on the health of the planet? From Fitbits to smart watches and Pokemon Go, wearable tech is a big trend, but how can we make these devices power themselves. There is a lot of excess energy when we walk and move, so can we use this to power our technology?

Episode 330 - A cells journey, from birth to death

Young Scientists of Australia — Mon, 10 Jun 2019 18:06:55 +1000

This week we dive into the complicated history of cells and try to figure out if you are still the same ship. How does a cell know what it wants to grow up to be? What helps it make the decision to be an optic nerve, a neuron or part of your jawbone? How old are all the cells in your body? Are they all the same age, and what does age even mean anyway? This week we dive into the complicated history of cells and try to figure out if you are still the same ship.

Episode 329 - Mysteries from the formation of our solar systems

Young Scientists of Australia — Mon, 03 Jun 2019 18:42:48 +1000

There are many things we don't understand from the formation of our solar system. Why did Jupiter end up with weird asymmetrical groupings of asteroids around it? Is there a region of dust free space around the sun? If there is why can't we find it? What caused the beautiful rings of dust millions of kms wide around Venus and Mercury? Where did that dust come from? All these questions and more as we unpack the hidden parts of our solar system.

Episode 328 - Mathematics and Nature, from Bees to Choruses of Frogs

Young Scientists of Australia — Mon, 27 May 2019 17:51:11 +1000

Mathematics is not just something humans can perform. It's present across the universe and especially in nature. So can animals understand abstract mathematical concepts? Can we learn from the different complicated algorithms and mathematical models used by animals to improve the internet of things? What can social media help tell us about both human and animal tourists to nature reserves?

Episode 327 - Hippos and Algae, Lions and Porcupines, plus Narwhals.

Young Scientists of Australia — Mon, 20 May 2019 20:46:13 +1000

What connects Hippos, Algae and keeping the rivers of Africa healthy? What causes Lions to square-off against Porcupines? What is keeping the Narwhal population healthy despite it's genetic diversity? We look at the strange interconnection between species and how small changes in one ecosystem can destabilise a whole species.

Hippos help keep the rivers and lakes of Africa healthy...through their poo.

Hippos are essential in pumping silicon from the savannah into the rivers and lakes of Africa.

Lions hunt lots of creatures, but what needs to happen for them to try attacking a Porcupine?

Porcupines vs Lion sounds like a March Mammal Madness battle, but what causes a Lion to go after such a tough prey?

The Narwhals population is rebounding but it its still at risk due to it's shallow gene pool.

Can a species survive with a shallow gene pool?

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

Young Scientists of Australia — Mon, 13 May 2019 14:37:48 +1000

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.

Episode 325 - Racing against time, from Box Jellyfish to Alzheimers

Young Scientists of Australia — Mon, 06 May 2019 20:29:11 +1000

Medicine is often a race against time, to diagnose, to develop and to treat. This week we're looking at new research which speeds up the detection of Alzheimers in patients and provides a chance to test out potential treatments. We also find out how University of Sydney researchers may help deliver a quick antivenom to those stung by the deadly box jellyfish. Plus ways to turn leftover bits of junk in blood plasma, into useful diagnosis tools that may help save time and lives in treatment without wasting more time on tests.

Episode 324 - Hunting for missing matter, gravitational waves and stellar deaths

Young Scientists of Australia — Mon, 29 Apr 2019 21:12:27 +1000

Hunting for missing dark matter or gravitational waves involves incredibly precise measurements. Scientists are constantly developing new measurement techniques to try and find new sources of data and test theories. Whether it be staring at the space between Andromeda and the Milky Way to find primordial black holes, to looking in the remnants of a white dwarf using spectroscopy. Plus ways to make the newer generation of gravitational wave detectors more accurate by listening to quantum noise.

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

Young Scientists of Australia — Mon, 22 Apr 2019 18:14:00 +1000

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 322 - Imaging strange objects in space (and on earth)

Young Scientists of Australia — Mon, 15 Apr 2019 22:27:30 +1000

Taking images of strange objects in space is incredibly complicated and requires both large telescopes, and even larger teams of scientists to pour over the data. Techniques, codes and algorithms to sift through that data to find the unusual patterns is an incredibly difficult and challenging task. However with it we can capture some incredible things whether it be images of black holes, to asteroids literally spinning themselves apart, or even missing endangered species here on earth.

Lagrange Point Episode 321 - Bacterial search engine, blending in with hosts

Young Scientists of Australia — Mon, 08 Apr 2019 18:07:35 +1000

Bacteria are all around us and inside our guts too. Yet despite this there is still so much we do not know about them. We keep discovering new types, new species and then they change the game by blending into hosts and having new side effects. We look at how microbial infections disguise themselves to blend in, how fungal infections deactivate alarm systems, and just how many unknown bacteria there are in your gut. We also find out about ways to tackle our lack of knowledge with bacterial search engines.

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

Young Scientists of Australia — Mon, 25 Mar 2019 18:01:01 +1000

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 315 - Asteroids, meteorites and the destruction of moons

Young Scientists of Australia — Mon, 25 Feb 2019 14:55:18 +1000

It's easy to think of the solar system as a static object that's always been there. But by studying asteroids, meteorites and moons we can piece together the often violent and dramatic history of our solar system. From Earth being bombarded by water bearing asteroids, to moons being broken apart and reformed around Neptune. We even follow up on some of the great work done by JAXA and the Hyabusa 2 mission. This week we look at some of the latest research into our solar system by studying the smallest often overlooked pieces.

Episode 314 - Ancient life and life in extreme places

Young Scientists of Australia — Mon, 18 Feb 2019 15:45:33 +1000

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

Young Scientists of Australia — Mon, 11 Feb 2019 16:51:56 +1000

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

Young Scientists of Australia — Mon, 04 Feb 2019 17:48:22 +1000

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 311 - Stellar deaths, black holes, white dwarf accomplices and crystal stars

Young Scientists of Australia — Mon, 28 Jan 2019 16:47:57 +1000

What happens when a star dies? We can investigate what is left behind at the scene of the crime to piece together the final moments of a star. Some become white dwarfs so cold and cool they crystallize with thick oxygen and carbon skins. Others collapse in on themselves becoming supernova in a catastrophic core collapse. But sometimes in complex binary systems there is an accomplice that pushes the star over the edge, into supernova territory. Plus super massive black holes can devour passing stars, but sometimes they have a little help.

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

Young Scientists of Australia — Mon, 21 Jan 2019 18:22:24 +1000

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 309 - Mysterious signals from outside our galaxy!

Young Scientists of Australia — Mon, 14 Jan 2019 17:40:22 +1000

Space is filled with incredibly strange objects, from black holes to neutron stars. In the right conditions these strange stellar objects create incredibly powerful radio bursts which give radio astronomers a treasure trove of data. From the WOW! Signal to Pulsars we recap the history of strange space signals, and we look at the modern hunt for Fast Radio Bursts (FRBs) and how the CHIME observatory in Canada is shedding light on this mystery.

Episode 308 - Farewell to phantom limb pain, and better prostheses

Young Scientists of Australia — Mon, 07 Jan 2019 16:42:33 +1000

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 299 - Redefining the kilogram a history of measurement

Young Scientists of Australia — Mon, 05 Nov 2018 17:05:36 +1000

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

Young Scientists of Australia — Mon, 24 Sep 2018 18:00:00 +1000

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?

Young Scientists of Australia — Mon, 20 Aug 2018 17:40:30 +1000

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.
