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.

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.

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.

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?

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.

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.

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.

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.

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.

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.

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?

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?

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?

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.

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.
