Viruses: Destruction and Creation • 2016

In recent years, eating has become a health hazard. We love our potato chips, candy, and fast food…however bad they are for our health. And we still continue to consume these products in ever greater quantities. After the war on tobacco, a new battle is underway: the fight for healthier food. So, why do we consume so much processed food and why are we so hooked on it? How exactly does the relentless agribusiness keep us coming back for more? How does it mold our tastes, influence our cravings and feed our addictions? The few independent researchers who dare raise concerns about processed food are often ignored. Opposite them, the giant multinationals who fund the majority of research into nutrition are highly organized, and present at every level of decision-making. They are even involved in government campaigns on nutrition and health. Remi, our French-American reporter, will investigate current eating habits in Europe and America, and meet those involved in this new global food war. We will hear from scientists tracking sugar addiction, the businessmen playing on our weaknesses, legal experts preparing to challenge the might of the industry, and simple lovers of good food. A compelling documentary that reveals the latest ways the agribusiness is trying to tempt us, and the ways we as consumers can try to resist.

On the front lines of the hunt for killer viruses, a shocking discovery is made: viruses, once thought to be a menace to humankind, may in fact be the ultimate creators. Since the beginning of time, they have played a critical role in evolution, shaping us and perhaps even creating us. How could that be? How can an entity seemingly programmed for destruction lead to genetic diversity and new species? To many people, viruses are simply agents for disease, but to Dr. Luis Villarreal, Director of the Center for Virus Research at the University of California Irvine, they may possess far greater power than originally thought. He guides us through evidence that viruses gave rise to the first complex cells, played a role in the diversification of life, changed how our young are born, drove evolution, and perhaps gave us emotions. One expert even suggests that an ancient virus could have entered our genes and rewired us for monogamy. National Geographic investigates a provocative new theory that suggests that all life - including humans - is descended from viruses. Taking us through African jungles in search for new strains, this episode of Explorer presents a startling new view of viruses - toward what may be a remarkable evolutionary moment: the rise of a new human species.

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.

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.
