They're fast and floaty, but sadly we don't have them in the UK. Laura, Emma and Antonia look at the cool use of physics that makes them levitate and compare energy use and infrastructure requirements to other forms of transport.

Fact check:

Antonia, Ellie and Tom discuss the history of the Moon missions, including the Apollo programme that started it all and the past and future of the ISS. The team explores the media hype and the differences surrounding the Artemis missions in comparison to those first voyages to space over 50 years ago. 

And how did they learn to do it? Ellie and Emma discuss what tool use actually is and the species that have adapted specific instruments to achieve a desired goal. From Veronika the cow to Jane Goodall we explore how far tool use has come and what the possibilities are for species and tools of the future.

Fact check:

The battery in electric vehicles makes them much heavier than traditional vehicles. Laura and Jasmin discuss how steel car components can be made lighter to offset this increased weight, what implications that has for other industries, and whether this would make the steel industry more sustainable.

They also discuss studies related to sauna usage, if cold showers make any difference, and if the Nordic countries have got the right idea 💡

Fact check:

Some gemstones are desired for their sparkle and rarity while others have practical applications in engineering and electronic components. Laura and Antonia look at different ways gems can be made in the lab, how valuable they are and consider how you could potentially make a lot of money from them.

Fact check:

Researchers were surprised to find that moss spores germinated after nine months hanging out on the outside of the International Space Station. Ellie and Laura dive into their research and go beyond it to look at why some things survive in space, the benefits of doing this sort of research and what it might mean for a more resilient ecosystem here on Earth.

Fact check:

Different nations have different approaches to testing and using chemicals to see how they can cause diseases. Antonia, Laura and Jasmin look at how chemicals are tested for toxicity, how harmful substances are controlled, and whether dose limits are important. They look at asbestos, radioactive substances, and more.

Fact check:

And is it a good idea? Laura, Jasmin and Antonia look at various scientific studies on growing crops and raising livestock in fields of solar panels to see what the effects are. They also look at some solar farms that are used in arid regions and the benefits they can have for crops and the environment.

Fact check:

And can we learn to live longer? Ellie, Jasmin and Emma discuss telomeres that form the ends of DNA strands, the long-lived members of the animal world, supplements and products to fight the signs of aging, and even the idea of living forever.
