The daylight robbery of precious crown jewels from the Louvre museum in Paris has us stealing your attention to inspect heists and crime scenes in science.

We explore how stealthy spiders use tricks and deceit to rob precious prey from one another, and we look at how seagulls and other birds have the advantage when it comes to stealing food from humans. We also learn how our immunological security systems try to prevent bacteria from doing an iron-heist from our cells and blood.

But what about figuring out whodunnit? Forensic ecologist and palynologist Professor Patricia Wiltshire shares how pollen can be instrumental when solving crimes and how thorough, detailed forensic work can help uncover the truth when unravelling mysteries.

We also hear about the tensions between elephants and humans in Kenya, why we prefer the taste of certain foods, and how the code to a famous puzzle-filled sculpture might have finally been cracked.

All that, plus many more Unexpected Elements.

Europe has a new entry/exit system based on biometric data. But what exactly is the science behind biometric data, how can we ensure it’s used responsibly, and can it be cracked?

We also look at how some animals use dung as biometric data with Dr. Adrian Shrader, how your walk can be used to ID you from Professor Mark Nixon, and why gold has its own special measurement. All that plus many more Unexpected Elements.

Presenter: Marnie Chesterton

Record high gold prices have us looking at the science of inflation, why gold is leaking from volcanoes, and entomologist Katy Prudic explains why shiny gold can be a good color for camouflage.

Plus the dark science going on in a gold mine, whether we can move at the speed of light, and the debate around golden rice. All that, plus more unexpected elements.

Egyptian strongman Ashraf Mahrous recently pulled two ships totalling 1,150 tonnes with his teeth, setting his sights on the Guinness World Record. Inspired by this story, this week we’re tackling the science of all things strong.

First, we find out about new research that could keep our muscles strong as we age. Next up, we discover why graphene is so strong and how it could help improve data storage.

We're then joined down the line by Dr Matt Caplan, an astrophysicist from Illinois State University, who tells us about his search for a weird substance called ‘nuclear pasta’. And no, you won’t find it in your local Italian restaurant.

Plus, find out how robo-exoskeletons can help you climb hills and why Ernest Shackleton’s Endurance was weaker than expected.

The launch of Taylor Swift’s much-anticipated 12th studio album, The Life of a Showgirl, has inspired this week’s episode of Unexpected Elements.

First up, we hear how a Brazilian songbird courts its mate as part of a boyband. We then find out about the microbes that dance to survive in their extreme habitat.

Next up, Professor Troy Magney, a forest ecophysiologist at the University of Montana, tells us about his TSWIFT machine and how it can assess the health of the planet’s forests.

Also in the programme, we find out why migratory birds trick weather data, how fish sing, and how hackers used SWIFT bank payments to nearly pull off a billion-dollar heist.

All that, plus many more Unexpected Elements.

This week marks 200 years since the first steam train pulled passengers over 26 miles of north-east England’s countryside, and started a revolution. Jump on board for show filled with train tales.

We explore Mumbai’s lunch delivery system – train based, of course, which has the sort of error rate that delivery firms arounds the world can only dream of. We ask what it takes to run a railway on time, and look at how the bullet train changed Japan, with history professor Jessamyn Abel.

For International Talk Like a Pirate Day on 19th September, we dig up a treasure chest full of pirate-inspired science.

First up, we peer down our microscopes at a bacterium that takes its inspiration from a pirate warship. Next, we turn our attention to scurvy, the disease that plagued mariners and is now making a comeback in the modern age.

We then get on the line with marine archaeologist Dr Sean Kingsley, who is about to set sail on a mission to survey the unexplored wrecks of Nassau.

Plus, we delve into the tricky topic of modern-day piracy and copyright, before testing our pirate knowledge in a swashbuckling quiz.

All that, plus many more Unexpected Elements.

The inauguration of Africa’s largest hydroelectric dam has us looking at how we decide when, where, and even whether to build dams.

But humans aren’t the only ones building dams – Loren Taylor of the Beaver Institute joins us to talk all about nature’s hydroengineers and the wide-spread benefits beavers (and their dams!) have on ecosystems.

Also on the program, how close are we to clean energy from space, the science behind holding your breath for a really, really, really, REALLY long time, and how natural sounds can be turned into musical instruments. All that, plus more unexpected elements.

Presenter: Alex Lathbridge with Andrada Fiscutean and Katie Silver

A dinosaur with metre-long spikes has been discovered. The species, Spicomellus afer, is from the Jurassic Period and is the oldest example of a group of animals called ankylosaurs.

The scientists behind the research have dubbed the new dinosaur the ‘punk rock dinosaur’, which led the Unexpected Elements team to go out searching for the science on all things punk, rock, and heavy metal.

First up, we find out what other punks might be lurking in the fossil record. And meet a pair of unconventional molluscs.

Next up on the set list, we investigate the physics underpinning mosh pits and the implications this could have for crowd control.

We speak with Anirudh Patel, an astrophysicist from Columbia University, who is scouring deep space to find out more about the origins of heavy metals.

And we dig into the unexpected link between water pipes and IQ.

All that, plus many more Unexpected Elements.

It’s August, and in the northern hemisphere, many people are hitting the beach to escape the summer heat. And that inspired us to investigate bucketloads of beach-based science.

First up, we find out about the forces that build and shape the seaside.

Next, we discover that the waves from the Hunga Tonga-Hunga Ha’apai eruption reached the atmosphere.

Speaking of waves, we’re joined by Dr Edward Hurme from the Max Planck Institute of Animal Behaviour, who tells us about his research into surfing bats.

And why are beaches disappearing?

All that, plus many more Unexpected Elements.
