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 409 - Stellar Weather, Life on other planets and Space Dust

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?

Episode 406 - Lifting mountains out of the ground…with rain

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.

Episode 400 - Nobel Prizes, Collaboration, and more sustainable trees

The Nobel Prize's legacy on gender and diversity is poor, but are they turning it around? We celebrate the winners of the Nobel Prize, but look critically at the challenges of the system. How do you recognize the collaboration of 100s or 1000s of people with a single award? Is science advanced through singular genius or the collaboration of many? How can CRISPR help us create a more sustainable planet? Growing trees that are easier to process but still able to thrive is possible with CRISPR. How can making trees with less lignin help make a greener planet?

Episode 397 - Ignobel Prize ‘20 - Physics

We celebrate the Ignobel Prizes once again, and this year we take a deep dive into the Physics prize for 2020. Faraday waves (standing waves in liquids or liquid filled objects) look pretty, but can anything filled with like have one? What about a worm? Can you make Faraday waves and resonant frequencies in Worms? What happens when a laser, a worm, and a speaker go into a lab? The result is an Ignobel Prize.

Episode 394 - Travelling through time with telescopes

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?

Episode 391 - Mysteries of the sun, stellar weather and magnetic fields

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.

Episode 387 - Black holes dancing, colliding and third wheeling

Scientists have discovered the closet black hole to Earth, but relax it's 1000 Light years away. Ever felt like a third wheel, just be thankful it's not a black hole. A binary star system that can be seen with the naked eye with a lurking black hole. Super massive  black holes are hard to get your head around but can unleash tremendous energy. When two super massive black holes dance around each other, the fireworks are spectacular. Predicting when two black holes will graze past each other helps us refine our understanding of the universe.

Episode 385 - Understanding what makes water stick together

What seems simple but it's deceptively complex. What makes water molecules stick together, or ice to float on top? Water has many mysteries, like ice floating on liquid. The key lies in the energy distribution. Shooting super high frequency lasers at water can help figure out what makes ice float or water stick together. Cheap and efficient ways to clean water is essential for saving lives across the globe. How can cyrstaline sponges help soak up bad chemicals like hexavalent chromium.

Episode 377 - Hubble turns 30 and still takes amazing images

We celebrate the life and achievements of Hubble Space telescope and all that have worked on it over it's 30 years in space (and many more before that). We look at the challenges faced by Hubble early on, and the amazing science it is helping contribute to today. From stars being born, to comets tearing themselves apart Hubble sheds light on amazing science. The images Hubble takes are iconic and often look like science fiction. Hubble manages to celebrate it's birthday by capturing images of a comet tearing itself apart.

Episode 366 - The YORP Effect, Star Brawls and Solar wind

What happens when stars brawl? What do they leave behind? When stars are dying they take down everything and everything around them from asteroids to other stars. What is the YORP effect? How do some tiny solar particles destroy an asteroid? Spiraling out of control, asteroids get YORP-ed at the end of a star's life. When a star gets to the end of it's life, it may swell in size, taking out asteroids and nearby stars.

Episode 344 - Colliding galaxies, stellar foundires and the emptiness of space

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?

Episode 342 - Better chemistry and physics in everyday objects

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.

Episode 338 - Exoplanets boiling and stretching, Goldilocks and Supernova

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?

Lagrange Point Episode 334 - Hidden in empty space

  • Space seems so incredibly vast and empty, but there is a lot hidden inside that seemingly empty void. From fungal spores to charged bucky balls. Radiation in space seeps everywhere and makes long term space travel dangerous for humans, but fungal spores cope just fine. Radiation can also cause beautiful light shows like the aurora but can make light tough for astronauts. How can we use social media to track the beautiful aurora light shows? How do we clean a space ship or space station?

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?
