What happens next after disaster strikes and people flee for safety? How do wildlife move in when people move out of a disaster zone? How do animals moving into an evacuated area change with no humans around? What is the most effective thing to do if you live near a disaster area? How do we assess risk and life expectancy impact of living near a disaster zone? Is it more dangerous to live near a nuclear plant or in the diesel smog of the big city?

From Fast Radio Bursts to Cosmic rays, interstellar mystery solving is a team effort. Mysterious repeating signals from space are tricky to localize, like spotting a person on the moon from here on Earth. What can fast radio bursts from billions of light years away tell us about the nature of the universe? How do you hunt for the source of a mysterious radio burst billions of light years away? How does a tiger, a balloon and Antarctica help us understand Supernova? What's the best place to hunt for cosmic rays; floating above Antarctica with a Super Tiger.

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?

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.

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?

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?

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?

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.

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.

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.

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.
