This week we’re looking at a political agreement that will hand back sovereignty of the Chagos Islands to Mauritius. In the 1970s, the UK removed the entire Chagossian population to make way for a US military base. The islanders have been fighting for their right to return ever since. If deal can be agreed, the islanders are hoping they will have the chance to go home. And this got us thinking about all things home-related. First up, we discover the intriguing reasons why you can’t smell your own home, then we take a closer look at our homes and all the creatures that live there, before finding out about the ‘home scars’ created by limpets. Next we hear from Dr Nadescha Zwerschke, a scientist who spent time on Rothera research station in Antarctica. She reveals how she made this isolated outpost feel like home. Also, we reveal that global talks to agree a reduction in plastics have collapsed, which could have an impact on all our homes from a pollution perspective.And finally – a type of pasta that would be no good for your homecooked recipes.

Super Science
Headlines that Canadian uranium deposits could make it a nuclear superpower has the Unexpected Elements team musing on all manner of superpowers. Tardigrades are an obvious candidate – boil them, freeze them, irradiate them in space, these adorable creatures are almost indestructible. We also meet Dr Deep Sea, Joseph Dituri, from the University of South Florida, who lived under water for 100 days and swears by it as a boost for our health. As the leader of the free world goes on an Amazon jungle tour, we talk tiny frogs, giant frogs and radiation tolerant frogs. We also hear how cancer survivors may have a secret superpower and how we’ve co-opted plants superpowers for medicines. Presenter: Marnie Chesterton, with Camilla Mota and Affelia Wibisono

It’s been 24 years since the release of Ridley Scott’s Gladiator, which left audiences captivated by the story of Maximus the gladiator, played by Russell Crowe. Now, Gladiator II is hitting the cinemas, so this week we enter the arena to take a look at some gladiatorial science.We hear about an angry little fish that fights off its rivals in mouth-to-mouth combat, we discover how humans have looked to nature to design better armour, and we find out about the perfume that Julius Caesar would have worn.We also speak to Dr Chris Nowinski, a former WWE professional wrestler who's now a pioneering neuroscientist. He’s leading some research into how to prevent concussions in sport, and is co-founder of The Concussion Legacy Foundation.That, plus many more Unexpected Elements.

Supermassive numbers
Russia has fined Google more than two undecillion rubles, which is more than 20 decillion dollars. How much you ask? 20 decillions is a 20 with 33 zeros behind it, more money than there is in the entire world!This unpayable fine inspired us to look at extremely large numbers, from the amount of cells in our body, to infinity hotels and beyond. Plus, two-time world memory champion Jonas von Essen teaches us how to memorise these supermassive numbers.Also, we unpick a dubious influential biodiversity statistic that has no basis whatsoever, and we look at the scientific tools of ghost hunting.Plus, to round it off, presenter Marnie looks at a sport with more possible moves than there are atoms in the Universe. Can you guess what it is?Presenter: Marnie Chesterton with Tristan Ahtone and Candice Bailey.
