Episode 426 - Tackling waste water and antibiotic resistance together

Hydrogen fuel promises a cleaner future, but the methods to make it are often dirty. A new approach recycles and treats waste water with sunlight to efficiently produce hydrogen. A new electrolysis approach turns waste antibiotics into hydrogen fuel cells. Removing antibiotics and other pharmaceuticals from waster water can be tricky, but a new technique turns that into green energy. Aquaculture is growing rapidly, but it is leading to antimicrobial resistance? What contributes more to antimicrobial resistance - fish farms or waste water? Incorrectly managed waster water can lead to superbugs.

Episode 425 - Tiny creatures with a huge impact on our oceans

Can you find fresh water in the middle of the ocean? What happens when a geyser of fresh water erupts from the sea floor into the ocean? A sudden freshwater spring can radically change the ocean floor. How do plankton shells and coral help us monitor a changing climate? Life in the oceans can help sequester carbon. We can track the way the climate has changed in the past by studying strontium isotopes in seawater. Changing climates can impact life in shallow and deep water, which can lead to changes in the carbon cycle. Tiny creatures like copepods can have a huge impact on our ocean food web. How do tiny creatures like copepods gather in ephemeral ocean zephyrs. Tiny vortexs can act as a gathering place for tiny but important sea creatures.

Episode 424 - Hunting for atmospheres on other planets

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.

Episode 423 - Humans vs Bacteria on earth and in space

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.

Episode 422 - Squid blending into starlight with Bio-luminescent bacteria

Squid can change colours, reflect light and blend in with their surroundings. How does the changing colours on squid skin work? What proteins and structures enable squid skin to reflect and amplify varying light? Squid can blend themselves into the starlight with the aid of bio-luminescence. The symbiotic relationship between bacteria and squid starts right after birth, and helps them shine to avoid predators and catch prey. A baby squid may not start out bioluminescent but a rapid spread of the right bacteria turns on the lights.

Episode 421 - March Mammal Madness ‘21 and Bats tuning out the world

We find out about the outreach and impact of March Mammal Madness. What happens when 65 animals face off for bragging rights? Find out in #2021MMM . By sharing science with a dramatic flair, #2021MMM has brought attention to 1000s of scientific papers. From 1% of US High school classrooms, to a global audience of young and old, #2021MMM shows how science does not have to be boring. How do bats tune out the background noise and hunt tiny prey? Using acoustic tunnel vision, bats are able to hone in on their tiny prey. By echoing quietly, bats can detect the smallest of bugs.

Episode 416 - Sourdough starters and less allergens in wheat and peanuts

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.   What can be done to make wheat and peanuts less dangerous for people with allergies? Can you make wheat and peanuts that are better for allergies?

Episode 415 - Greener ways to make Hydrogen and Ammonia

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?

Episode 414 - The active life and dramatic death of galaxies

Can a galaxy really die? What would that even look like? We know that stars can erupt into supernova, form black holes or fade away but what happens to old galaxies? What happens to a galaxy when it looses all it's fuel for growing new stars? Which galaxies are the most active and pulsing with light? Active galaxies often shine vibrantly from their core, but what causes periodic bursts of energy. NASA Goddarrd researchers have discovered the 'Old Faithful' of Galaxies.

Episode 413 - Detecting gene doping in sport, and the strange air of gyms

You've probably heard of CRISPR, but what does it mean for the world of professional sports? How could gene-doping be detected by sports administrators? Could you tell if someone had used CRISPR to 'dope' their performance?  WADA considers gene editing a form of doping, but how can you detect it? What happens when you mix sweat, gym equipment and cleaning products? When you exercise you release a 3-5 times the amount of chemicals than a sedentary person. What happens to the mix of sweat, amino acids and cleaning products in the air of a gym?

Episode 412 - Magnetic Glues and Chemical gears

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.

Just how old are continental plates? When did plates sliding around and over each other really take off? What can rocks in the Canadian tundra tell us about the ages of the continents? The formation of continents led to a transformation of our planet and it's atmosphere - so when did it start? How can Australia have so many volcanoes on it's east coast despite being so far from the Pacific ring of fire? What causes Australia's mysterious volcanoes? Volcanoes in Alaska may be linked together in one super volcano. The Aleutian islands many volcanoes may be more linked than we thought.

Episode 408 - Life in deep sea soil, and blending in amongst leaves

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?

Episode 407 - Random generating DNA and random mouse movements

Random numbers are incredibly important for our digital economy, so how do we generate them? What is the best way to make a random number: roll a dice, lava lamp, guess, DNA? What connects lava lamps, e-commerce and synthetic DNA? How can we better generate random numbers using synthesized DNA. How do your mouse movements reveal about your decision making process. Do mouse movements help us identify risk takers or keen deliberators. Whether you know it or not, your mouse moving may be part of your decision making process.
