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.

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.

Of all the diseases that plague humankind, malaria has put up one of the longest, toughest fights. More than 200 million people fall ill and 600,000 die of it every year, making it among the world's deadliest diseases. The vast majority of those fatalities are young children - an average of one child every minute. But medical science may now be at an exciting turning point. Filmed with intimate access to key scientists on four continents, this documentary tells the inside story of the development of a new malaria vaccine that could change the very nature of the fight. It's hoped that the vaccine, dubbed R21/Matrix-M and developed by many of the same team behind the Oxford/AstraZeneca Covid-19 vaccine, will be the first to meet the World Health Organization's target of 75 per cent efficacy.
