Monty the giant schnauzer won best in show at the Westminster Kennel Club Dog Show. And rather than thinking of all things canine, this week the Unexpected Elements team turn their attention to all things giant.

First, we find out how a giant virus could help keep our planet cool.

Next up, we discover the origins of enormous Greek characters, such as the Titans and the Cyclops.

Plus, we’re joined by Professor Shinobu Ishigaki, director of the Museum of Dinosaur Research at the Okayama University of Science. He tells us about the ginormous footprints he found in the Gobi Desert, and what they could teach us about herbivorous dinosaurs.

That, plus many more Unexpected Elements.

Presenters: Caroline Steel, with Chhavi Sachdev and Camilla Mota.
