Everyone needs a hero
Notas do episódio
A mysterious vigilante in Mexico nicknamed “Batman” has inspired the Unexpected Elements team to investigate the science of superheroes.
First up, we explore whether a Batman’s presence can actually change human behaviour. One unusual psychology experiment suggests that people may be more likely to perform acts of kindness when a caped crusader appears nearby.
Then we discover a real human superpower: echolocation. Used by bats and many other animals, it turns out humans can learn to navigate the world using sound as well.
Next, we meet Mexico’s original Bat Man, conservationist Dr Rodrigo Medellín. He joins us to bust myths about a much maligned mammal, reveal how one species helps make tequila possible, and confess to keeping vampire bats in his bathroom.
Plus, how environmental DNA is helping researchers map biodiversity across the Arctic Ocean and a reflection on scientific heroes. Are great discoveries are ever really the work of just one person?
All that, plus many more Unexpected Elements.
