Somewhere in your body, your immune system just quietly killed one of your own cells, stopping it from becoming cancer, and saving your life. It does that all the time. The vast majority of cancer cells you develop will be killed without you ever noticing. Which is an incredibly hard job because of what cancer cells are: parts of yourself that start to behave as individuals even if it hurts you. What is cancer and how does your body kill it all the time?

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.
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.
Insomniac Michael Mosley finds out what happens if we don't get enough sleep and looks at surprising solutions to help us get more.

From the first row of planted crops, the practice of agriculture rendered man's hunter-gatherer lifestyles obsolete in favor of settled life and stable food supplies. This led to a skyrocketing population and enabled humans to develop skills outside of gathering the food needed to survive.

We’ve heard for years about the dangers of eating too much fat or salt. But there have never been recommended limits for sugar on Canadian food labels, despite emerging research that suggests the sweet stuff may be making more of us fat and sick. In the fifth estate’s season premiere, Gillian Findlay digs into the surprising science — and the reaction from the food industry — to reveal The Secrets of Sugar. Has the sugar industry been hiding an unsavoury truth from consumers?
