Why are ultra-processed foods so irresistible, and how they have come to dominate food culture? Dr Chris van Tulleken features interviews with former food industry insiders who talk openly about the way in which popular foods have been designed to be irresistible. Food companies go to extraordinary lengths to ensure their products connect with consumers - from using brain scans to assess the deliciousness of ice cream to carefully engineering the sound of a crunch. Ultra-processed foods are hyper-delicious and super-convenient, have long shelf lives and are extremely cheap. But a growing body of evidence is linking these products to our declining health.

Lyme disease, a mysterious tick-borne illness, is the fastest spreading vector-borne disease in the United States, and over the past decade, the tick that carries Lyme has been spreading across Canada with alarming speed. Ticked Off: The Mystery of Lyme Disease, is a fascinating and eye-opening documentary that explores a disease that has devastating effects, is often misdiagnosed and mistreated, and continues to be mired in a medical controversy. More than 30,000 cases are reported in the USA every year, but the real number could be as high as 300,000. And despite hard evidence that the Lyme-carrying, deer tick has already established populations across Canada, some people claim that patients here are still being told that they cannot contract Lyme in this country. Doctors agree that if it’s caught early Lyme disease can usually be cured with two to four weeks of antibiotics. There are others who believe that if it’s not caught early, the infection can develop into a debilitating condition they call Chronic Lyme. Yet unlike West Nile, Encephalitis or SARS, where the medical profession and scientists joined forces to find better treatments or a cure, many patients, who claim to have chronic Lyme, say that they are being denied treatment and left to suffer. So why is this happening?

Is there any way to slow or even prevent the ravages of time? Veteran presenter Johnny Ball looks back over the 45 years that Horizon, and he, have been on air to find out what science has learned about how and why we grow old. Charting developments from macabre early claims of rejuvenation to the latest cutting-edge breakthroughs, Johnny discovers the sense of a personal mission that drives many scientists and asks whether we are really any closer to achieving the dream of immortality.

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.
