Following the release of his book on the gut, Dr Michael Mosley returns to Insight for a discussion with fellow experts and ordinary Australians about how the gut can play an integral role in our overall physical and mental health.Increasingly, research is shedding light on the previously mysterious world of the gut and the 1-2 kilograms of microbes that live there, forming each person's unique microbiome , the genetic ecosystem of bacteria, viruses, fungi and other organisms that lives inside and on our bodies from birth. This week's Insight tackles the ground-breaking science and personal stories around the gut's potential to change our lives.
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.
Infertility affects 1 in 8 couples worldwide. But in the last 40 years, more than 5 million babies have been born using in vitro fertilization (IVF). How does it work? Nassim Assefi and Brian A. Levine detail the science behind making a baby in a lab.
Diseases that were largely eradicated in the United States a generation ago—whooping cough, measles, mumps—are returning, in part because nervous parents are skipping their children’s shots. NOVA's "Vaccines—Calling the Shots" takes viewers around the world to track epidemics, explore the science behind vaccinations, hear from parents wrestling with vaccine-related questions, and shed light on the risks of opting out.
The use of embryonic stem cells has ignited fierce debate across the spiritual and political spectrum. But what if we could create manmade stem cells - or find super cells in adults that could forever replace embryonic cells and remove the controversy? Today, we are on the brink of a new era - an age where we may be able to cure our bodies of any illness. Stephen Hawking has spent his life exploring the mysteries of the cosmos, now there is another universe that fascinates him - the one hidden inside our bodies - our own personal galaxies of cells. Hawking takes us on a fascinating journey exploring what these wondrous and baffling mechanisms are capable of. He is joined by the scientists who are on the front lines of discovery in this field including Dr. Doris Taylor who is customizing a donor's heart with the recipient's stem cells - her goal is to revolutionize heart transplants, Dr. Paul Lu and Dr. Mark Tuszynski may have created a breakthrough that could cure paralysis, and Dr. Vincent Giampapa who believes that stem cells can be used to stem the tide of aging and create a fountain of youth.

Dr Kevin Fong examines what can be done to reduce the number of mistakes being made by surgeons in the operating theatre. Speaking to professionals in high-pressure careers - including airline pilots, firemen and Formula One pit workers - he explores the coping mechanisms they each employ when faced with emergency situations, and looks at how these tactics could be transferred to the world of surgery.
This week, we meet a girl whose heart has formed outside her ribcage, a man who can spend nine minutes underwater without taking a breath, a woman who is growing a second skeleton and a paralysed man who is regaining movement thanks to a chip implanted into his brain that can 'read' his brain signals.
