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.

One of the key players of our immune system is the complement system. An army of millions and trillions of tiny bombs, which work together in a complex and elegant dance to stop intruders in your body.

Growing distrust in GMOs, pharmaceuticals and non-natural solutions has pushed families to seek more 'natural' approaches to medical issues - sometimes with fatal consequences.

The story of how the life-saving cervical cancer test became an ordinary part of women's lives is as unusual and remarkable as the coalition of people who ultimately made it possible: a Greek immigrant, Dr. George Papanicolaou; his intrepid wife, Mary; Japanese-born artist Hashime Murayama; Dr. Helen Dickens, an African American OBGYN in Philadelphia; and an entirely new class of female scientists known as cyto-screeners. But the test was just the beginning. Once the test proved effective, the campaign to make pap smears available to millions of women required nothing short of a total national mobilization. The Cancer Detectives tells the untold story of the first-ever war on cancer and the people who fought tirelessly to save women from what was once the number one cancer killer of women.
