Perseverance has landed and begun it's long mission, but how can scientists on Earth help research on Mars? Can we study life on Mars here on Earth? Robotic missions aren't the only way Martian rock has made it's way to Earth. Rare meteorites from Mars can be used to test how life would grow in Martian soil. Just how old is the Jezero crater?

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.

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?

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.

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?

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.

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.

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.

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?

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.
