In the US, 80% of girls have been on a diet by the time they're 10 years old. In this honest, raw talk, neuroscientist Sandra Aamodt uses her personal story to frame an important lesson about how our brains manage our bodies, as she explores the science behind why dieting not only doesn't work, but is likely to do more harm than good. She suggests ideas for how to live a less diet-obsessed life, intuitively.

What makes us feel good about our work?

What motivates us to work? Contrary to conventional wisdom, it isn't just money. But it's not exactly joy either. It seems that most of us thrive by making constant progress and feeling a sense of purpose. Behavioral economist Dan Ariely presents two eye-opening experiments that reveal our unexpected and nuanced attitudes toward meaning in our work.

Why Humans Run the World

70,000 years ago humans were insignificant animals. The most important thing to know about prehistoric humans is that they were unimportant. Their impact on the world was very small, less than that of jellyfish, woodpeckers or bumblebees.

A thrilling look at the first 21 days of a bee’s life

We’ve heard that bees are disappearing. But what is making bee colonies so vulnerable? Photographer Anand Varma raised bees in his backyard — in front of a camera — to get an up close view. This project, for National Geographic, gives a lyrical glimpse into a bee hive — and reveals one of the biggest threats to its health, a mite that preys on baby bees in the first 21 days of life.

Your brain hallucinates your conscious reality

Right now, billions of neurons in your brain are working together to generate a conscious experience -- and not just any conscious experience, your experience of the world around you and of yourself within it. How does this happen? According to neuroscientist Anil Seth, we're all hallucinating all the time; when we agree about our hallucinations, we call it "reality." Join Seth for a delightfully disorienting talk that may leave you questioning the very nature of your existence.

Food On The Brain

Michael Mosley and James Wong explore the effect that our food has on our most important and, in terms of energy consumption, our greediest organ. It influences our diet by generating cravings for foods such as fat - the most energy-rich food of them all. James heads off to Peru to reveal the surprising link that fat-rich, indulgent chocolate has with breast milk. Sometimes these cravings almost become an addiction - like coffee for example. So we visit a remarkable lab where a team is studying the effect of caffeine on bees and how that may help explain the hold that caffeinated drinks have over us. Together, Michael and James take on some of the hottest chillies on the planet to show what the burn does to our brains. Using the latest imaging techniques and incredibly detailed specialist photography, this is a whole new way of thinking about our relationship with food and the powerful effect it has on our minds.

The Pioneers

Many clinical trials target the nation's most acute health issues. With deaths from liver disease soaring by 40 per cent in a decade, more and more patients are waiting for vital liver transplants. There is a shortage of organ donors and many donated organs are rejected as only those in excellent condition are considered suitable for a transplant procedure. Surgeons Richard Laing and Thamara Perera are part of a team at QEHB trialling a revolutionary way to tackle this crisis, by maximising the number of donor organs that can be safely re-used. The film follows the trial every step of the way, as Richard receives a donor liver that would usually be rejected and tries to prove it is viable for transplant by rejuvenating and testing it on a perfusion machine. This machine sustains the liver by mimicking the supply of blood, oxygen and nutrients an organ receives inside a live, healthy human body. Once the donor liver has proved itself fit for transplant, the surgical team start to remove grandmother Connie O'Driscoll's severely diseased liver. Once the donor liver has been disconnected from the perfusion machine, they have just 20 minutes to place it in Connie's body and plumb it into the complex and delicate network of hepatic blood vessels.
