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?

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.

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.

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.

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?

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?

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?

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.

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.

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.

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?

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.

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?

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?

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.

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.

There are whole bundles of random RNA fragments in blood plasma, but these can be used to help diagnose specific issues.
The box jellyfish is just one of the many things in Australia that is trying to kill you, but now it's slightly less deadly thanks to University of Sydney researchers.
