Our skin is the largest organ in our bodies, with a surface area of about 20 square feet in adults. When we are cut or wounded, our skin begins to repair itself through a complex, well-coordinated process. Sarthak Sinha takes us past the epidermis and into the dermis to investigate this regenerative response.
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.
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.

Horizon investigates a new era of Alzheimer's research, which is bringing hope to millions of sufferers across the world. New scanning and gene technology is allowing scientists to identify the disease at its earliest stages, often 15 years before symptoms appear and the brain cells are destroyed. A series of new drugs trials in Colombia, the USA and Europe are showing startling success in reducing beta amyloid, the protein which is a hallmark of the disease. It is also becoming clear that changes in lifestyle can prevent the development of the disease. A new system inside the brain has been discovered which clears amyloid when we are in deep sleep, but allows it to accumulate if we don't sleep well. The programme reveals that for sufferers in the early stages of the disease, brain connections, or synapses, can be strengthened and even replaced by absorbing enough of the right nutrients. A UK-wide trail helps sufferers in the early stages to concentrate on improving everyday tasks, and in the process not only make their lives easier, but helps to reactivate the planning and organisational parts of the brain. In an ageing world, where the biggest risk of developing Alzheimer's is old age, the scientific breakthroughs in Alzheimer's disease are bringing hope where once there was despair.
