Unexpected Elements

Unexpected Elements

BBC World Service

The news you know, the science you don’t. Unexpected Elements looks beyond everyday narratives to discover a goldmine of scientific stories and connections from around the globe. From Afronauts, to why we argue, to a deep dive on animal lifespans: see the world in a new way.

  • 467 - 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?

  • 466 - The Swing of Things

    On this weekend ahead of the US election, we clock the importance of so-called swing states – and swing into action looking into not politics, but the science of swings.

    We examine how a pendulum swung by French physicist Foucault demonstrated that the earth is spinning, and hear about how the gibbon became the king of swingers – and what current-day elite climbers can learn from them.

    We also hear from educator Francis Mavhunga at the University of Eswatini who has regularly used swings in his physics classes, and now shows a new generation of teachers how to integrate children’s lived experiences into the classroom.

    Plus, how science has revealed new secrets about the ancient silk road, and what your brain can see when your eyes can’t. And, just to swing back to the beginning, presenter Marnie Chesterton digs into the archives to find out if science and tech can provide a foolproof voting system, and how astronauts vote.

  • 465 - Mystery blobs

    White blobs have been appearing on the beaches in Newfoundland, Canada. They’re kind of doughy-looking, and smell of vegetable oil. As yet, officials are not sure what they could be. Of course, this got the Unexpected Elements team intrigued, so we decided to dedicate the programme to the weird world of blobs, slime and bizarre things that wash up onshore.

    We hear about the fabulous hagfish, which produces copious amounts of snot-like slime to defend itself from predators.

    But what makes slime so slippery in the first place? And why is ketchup so hard to get out of a bottle? And what makes quicksand so difficult to escape from? It’s all down to fluid dynamics. Professor Daniel Bonn, from the University of Amsterdam, explains the physics behind all these sticky situations.

    Also this week, we find out more about a shipment of bath toys that tumbled overboard, and how they have helped scientists to decipher ocean currents.

    Plus, we discover more about the restoration of mangrove forests, how flowers can cause weird dreams, the size of the biggest black forest gateau and a species of plankton and how it floats.

  • 464 - TV made me do it

    Spoiler alert! At the end of the fourth season of Emily in Paris, the protagonist sets off to go to Rome. In response, the French President Emmanuel Macron has promised that “we will fight hard” to keep Emily in Paris in France. Why does he care so much? A recent study suggests that 38 per cent of all visitors to Paris name the show as one of the reasons for visiting. Inspired by this factoid, we started thinking about the ways in which TV can influence us.

    We examine how Star Trek inspired mobile phones – and the outfit of one of our panelists. Plus, we find out more about the impact Dana Scully from The X Files had on a generation of girls. And what does psychology say about fandom?

    But how can science influence the films? We speak to Dr Adam Rutherford, a geneticist, broadcaster, and, importantly, scientific advisor for movies. What does that last role involve? Which films get the science right? And is scientific accuracy important for a Hollywood blockbuster?

    Also in the programme, we hear about the mysterious recent earthquakes in Ethiopia, and Unexpected Elements listeners with visual impairments get in touch to share the secrets of what they can see inside their heads. And finally, we take a look at the surprising connection between cricket and statistics.

  • 463 - The world's longest treasure hunt

    After 31 years, a mammoth treasure hunt consisting of solving eleven cryptic clues has finally concluded. A replica of the final prize – a golden owl – was dug up in France, leaving fellow treasure hunters both disappointed and relieved.

    Inspired by this pursuit, the Unexpected Elements team unearth some of science’s hidden gems. From the potential resurrection of ancient healing tree balm to the world’s rarest stone, and even how cats could help solve crimes. The team are also joined by astrobiologist Nathalie Cabrol to speak about the potential treasures hiding on another moon in our solar system. Along the way, our panel have their own clues to crack as they take on a mini hunt of their own to find the location of a scientific golden nugget.

    Plus, we solve the mystery of a moth which ended up 4000 miles from home, hear what our brains see when we can’t and talk about returning treasures to where they came from.
