Bacteria, viruses, but also fungus spores, algae, pollen, and even insects: microorganisms are constantly drifting through the sky. How can so many living beings find their way into the air and be circulating in our atmosphere? How do they survive? What is their influence on our lives and our entire living world? Biodiversity, health, climate - scientists are only now discovering just how much this discreet airborne "plankton" affects our lives and the entire ecosystem on Earth. But despite its many virtues, this magic matter is now under threat from human activity. With help from experts and using 3D visual effects, this scientific investigation will take us to the heart of a world that is still very little understood, and will reveal the diversity and fragility of the air we breathe.

It was 1952, and polio had reached outbreak levels in America. There was no known cause, no cure, and no help in sight for parents desperate to protect their children. Our nation's hope was placed in a 33-year-old scientist, working from a basement lab in Pittsburgh. His name was Jonas Salk, and in just a few years, he would bring infantile paralysis to its knees and change the course of medical history. Travel back to a world gripped in fear and see how Dr. Salk, with his dedicated staff, a young charity, and a faithful nation, came together to conquer polio.

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.

Michael Mosley has set himself a truly ambitious goal: he wants to live longer, stay younger and lose weight in the bargain. And he wants to make as few changes to his life as possible along the way. He discovers the powerful new science behind the ancient idea of fasting, and he thinks he's found a way of doing it that still allows him to enjoy his food. Michael tests out the science of fasting on himself - with life-changing results.
