Filmmaker and artist Yann Arthus-Bertrand spent 3 years collecting real-life emotional stories from more than 2,000 women and men in 60 countries. Those emotions, those tears and smiles, those struggles and those laughs are the ones uniting us all. A combination of testimonies and exclusive aerial images, HUMAN is a unique documentary. This sensitive experience is an introspection into whom we are today as a community but also and most importantly as an individual. Through wars, inequalities, discriminations, HUMAN confronts us with the realities and the diversity of our human conditions. Beyond this darker side, testimonies show the empathy and the solidarities which we are capable of. All these contradictions are ours and HUMAN leads us to reflect about the future we wish to give to people and the planet today.

The terrorist group Boko Haram is responsible for thousands of deaths in Nigeria. Now, the government is determined to drive these militants from the country. But is the hunt for insurgents causing as much harm as it's preventing? Former Navy SEAL and new VICE correspondent Kaj Larsen travels to Nigeria to see what this cat-and-mouse game means for the people caught in the middle of the fight. 'Unnatural Selection': For centuries, scientists have been working to change the genetic traits of plants and animals. Now, the new gene-editing method CRISPR has made that process astonishingly simple - so simple it could easily be used on humans. Isobel Yeung reports from Brazil, Scotland, China and the U.S. on the technological advances that could reshape evolution as we know it.

A look at the very real impact the Back to the Future movies have had on our culture. What was once a little idea that spawned a tightly-focused documentary has grown into something truly amazing over two years of filming. Back in Time is a cinematic monument to the vastness of the trilogy's fandom. In addition to the footage and interviews revolving around the time machine itself, the crew found that simply by delving into the impact of the trilogy an epic journey began to unfold before them. The crew captured countless hours of footage during filming. From Steven Spielberg to Robert Zemeckis and Bob Gale, to the Sheas and Hollers, and from James Tolkan and Lea Thompson to Christopher Lloyd and Michael J. Fox, Back in Time features interview after interview that simply must be seen.

This episode explores the palaeogeography of Earth over millions of years, and its impact on the development of life on the planet. Tyson starts by explaining that the lignin-rich trees evolved in the Carboniferous era about 300 million ago, then explains on the nature of plate tectonics that would shape the landmasses of the world and the asteroid impact that initiated the Cretaceous–Paleogene extinction event, leaving small mammals as the dominate species on earth. Earth's landmasses are expected to change in the future and postulates what may be the next great extinction event.

The use of embryonic stem cells has ignited fierce debate across the spiritual and political spectrum. But what if we could create manmade stem cells - or find super cells in adults that could forever replace embryonic cells and remove the controversy? Today, we are on the brink of a new era - an age where we may be able to cure our bodies of any illness. Stephen Hawking has spent his life exploring the mysteries of the cosmos, now there is another universe that fascinates him - the one hidden inside our bodies - our own personal galaxies of cells." Hawking takes us on a fascinating journey exploring what these wondrous and baffling mechanisms are capable of. He is joined by the scientists who are on the front lines of discovery in this field including Dr. Doris Taylor who is customizing a donor's heart with the recipient's stem cells - her goal is to revolutionize heart transplants, Dr. Paul Lu and Dr. Mark Tuszynski may have created a breakthrough that could cure paralysis, and Dr. Vincent Giampapa who believes that stem cells can be used to stem the tide of aging and create a fountain of youth.

Humanity’s potential seems limitless. But could we become as powerful as God? Scientific breakthroughs grant our species seemingly divine abilities. Biologists tinkering with DNA are figuring out ways to grow new life forms, while neuroscientists try to create artificial consciousness. Statisticians around the world are using big data to predict the future and computer scientists have discovered a "God algorithm" that could solve any global problem in an instant. But to truly become God, we not only have to be all knowing, but all being. Quantum physicists are figuring out how to teleport matter at the speed of light!
