Surgeons often have to deal with the consequences of violent attacks - becoming all too familiar with patterns of public violence, and peaks around weekends, alcohol-infused events and occasions that bring together groups with conflicting ideals. Professor Jonathan Shepherd not only recognised the link between public violence and emergency hospital admissions, he actually did something about it. A...

Doyne Farmer is something of a rebel. Back in the seventies, when he was a student, he walked into a casino in Las Vegas, sat down at a roulette table and beat the house. To anyone watching the wheel spin and the ball clatter to its final resting place, his choice of number would’ve looked like a lucky guess. But knowing the physics of the game and armed with the world’s first wearable computer, w...

Elephants are the largest living land mammal and today our planet is home to three species: the African bush elephant, the African forest elephant, and the Asian elephant.

These gentle giants' evolutionary story and its pa...

While she has spent her career exploring its fundamental nature, much of her free time has involved trying to defy it - from scuba diving in the Indian Ocean to piloting small aircraft over the Canadian waterfalls. Her ultimate ambition was to escape gravity’s clutches altogether and become an astronaut, a dream that was snatched awa...

When you think of Artificial Intelligence, does it inspire confidence, or concern? Although it's now generally accepted that this technology will play a major role in our future, a lot of conversations around AI and machine learning come back to the argument over us losing control and robots taking over. Happily, Neil Lawrence has a more optimistic view of the power of AI, and how we might navigat...

A frozen, white world at the far-reaches of the globe, where you're surrounded by snow and silence, might sound rather appealing. Factor in temperatures that drop to -57°C and a few of us might be put off - but for glaciologist Liz Morris, that's very much her happy place. Liz is an Emeritus Associate at the University of Cambridge’s Scott Polar Research Institute, and was among the first British...

Named after a beast from Greek mythology, the harpy eagle is widely considered to be the most powerful bird of prey due to its strong legs and huge talons. With a crown of feathers atop its head, and known for eating monkeys and sloths, this regal-looking raptor dominates the rainforest canopies across much of South and Central America. Presenter Adam Hart looks into the folklore and cultural impo...
