A science heist

Unexpected Elements

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.
