Biology stands on the brink of a shift in the understanding of inheritance. The discovery of epigenetics hidden influences upon the genes could affect every aspect of our lives.
When you breathe, you transport oxygen to the body’s cells to keep them working, while also clearing your system of the carbon dioxide that this work generates. How do we accomplish this crucial and complex task without even thinking about it? Emma Bryce takes us into the lungs to investigate how they help keep us alive.
Thought of as a modern phenomenon, it actually started over 400 years ago with a spate of botched nose jobs. Since then, surgeons have been entranced with the idea that not only could they fix the body, but could even fix our sense of self-esteem. Presenter Michael Mosley undergoes both 16th-century bondage and 21st-century botox in his journey of discovery.
Think you know your baby? Think again. This beautifully shot, heart-warming and scientifically revealing film, narrated by Martin Clunes, brings you babies as you've never seen them before. The first two years of our lives are the most critical of all. We grow more, learn more, move more and even fight more than at any other time in our life. We have to master the complex skills of walking, talking and relating to the world around us. But we are not yet built like an adult. We have more bones in our body at birth than an adult does, yet we don't have kneecaps. We laugh 300 times a day as a baby, but in the first few months we can't produce tears when we're upset. Secret Life of Babies reveals all these facts and more, telling incredible stories of babies' resilience and survival skills to boot. This film will surprise, move, amaze and delight all those who have ever come into contact with a baby, whilst taking you from the moment of birth, through to the point where language begins, memories start to kick in, and a new phase of their lives takes over. This is the Secret Life of Babies.

We hear about calories all the time: How many calories are in this cookie? How many are burned by doing 100 jumping jacks, or long-distance running, or fidgeting? But what is a calorie, really? And how many of them do we actually need? Emma Bryce explains how a few different factors should go into determining the recommended amount for each person.
Over 62 per cent of adults in the UK are currently overweight or obese and this figure is set to rise. A common attitude is that obese people should be ashamed - it is their fault, they have no will power and if they could just 'eat less and exercise more', the problem would soon be solved. Yet, despite millions of pounds being spent on this simple message, the UK is getting fatter every year. Cambridge geneticist Dr Giles Yeo believes that for many obese people, simply eating less is a lot harder than you might think - and he is taking a road trip around the UK and America to uncover why. He meets the real people behind some of the more shocking newspaper headlines and, through their stories, reveals surprising truths which dispel commonly held myths about obesity. He gains access to scientists and doctors trialling cutting-edge techniques to tackle the crisis - from a 'miracle' hormone injection to a transfusion of faecal matter, and even learns a thing or two about his own size and relationship with food.
