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.

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.

The Honest Supermarket: What's Really in Our Food

For every pound we spend on food shopping, 77p goes to the supermarkets, giving them a huge influence over what we eat. But can we trust the supermarkets to tell us the truth about what we are buying and how it was produced? Or do their profits come first? In an experiment to discover the hidden truths about our everyday foods, Horizon has built the first ever truly 'honest supermarket'. Drawing on the latest scientific research and leading experts from across the UK, the team have built a supermarket where the products are labelled with the real story of how they are produced and their effect on us and the environment. We invite the British public to come in and discover the truth about their favourite foods. And in our on-site lab, new scientific discoveries reveal the food facts the supermarkets aren't telling you. Presented by Dr Hannah Fry and dietician Priya Tew, The Honest Supermarket takes a cold hard look at what's really going on with the food we eat. From new research that reveals you're likely to be ingesting plastic particles along with your bottled water to the lab tests that uncover the disturbing truth about just how old your 'fresh' supermarket fish really is… You'll never look at the food on your supermarket shelves in the same way again.

What is leukemia?

Stem cells found in the bone marrow are crucial for our health because they are needed to become new blood cells that sustain and protect our bodies.

Danilo Allegra and Dania Puggioni explain how this happens and how certain treatments provide hope for those suffering from the disease.
