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.

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?

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.

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.

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?

What is the space around the sun like? Cold? Hot? Dusty? How does the space around the Sun change over time? Does the Sun suck up dust in the solar system, or blow it out? What can we learn about stellar weather in our neighbouring stars. Red Dwarfs are one of the most common stars in our Galaxy, but also produce lots of flares. Are rocky planets in Red Dwarf's habitable zone safe from stellar weather?

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.

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?

The sun contains many mysteries, which are hard to unravel without special space probes. Why is the sun's corona so much hotter than the sun's surface? What helps form the biggest solar flares? When two arches of the sun's magnetic fields meet it can create some dangerous flares. Solar storms and solar flares can destroy satellites, power grids and spaceships. How can we better predict stellar weather and avoid disaster? Mapping out the Suns magnetic field can help us better predict stellar weather.

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?
