Three million years ago, camels roamed through Greenland’s endless forests and our ancestors lived in the trees. It all came to an end with the Ice Ages. What died and what survived, as natural selection shaped the evolutionary tree during this epochal shift from hot to cold? Until now, scientists have known less about the natural world before the Ice Age than they did about the age of dinosaurs, which ended 64 million years ago. A new discovery is set to reveal this lost world, species by species. Led by Danish gene-hunter Eske Willerslev, a team of scientists for the first time in history is sequencing DNA from before the Ice Age. The picture that emerges is of a hot planet, when forests blanketed the Arctic and carbon levels matched those in our atmosphere today. Is this a portrait of our own climate future?

Having to prove the existence of God to an atheist is like having to prove the existence of the sun, at noon on a clear day. Yet millions are embracing the foolishness of atheism. “The Atheist Delusion” pulls back the curtain and reveals what is going on in the mind of those who deny the obvious. It introduces you to a number of atheists who you will follow as they go where the evidence leads, find a roadblock, and enter into a place of honesty that is rarely seen on film.
A documentary of insect life in meadows and ponds, using incredible close-ups, slow motion, and time-lapse photography. It includes bees collecting nectar, ladybugs eating mites, snails mating, spiders wrapping their catch, a scarab beetle relentlessly pushing its ball of dung uphill, endless lines of caterpillars, an underwater spider creating an air bubble to live in, and a mosquito hatching.
A desktop documentary that focuses on the Golden Record that NASA sent into space in the late 1970s. The piece reflects on issues such as the power of scientific discourse to produce revisions of the world, the evolution of the concept of the archive and the resignification of borders in the rhetoric of space colonialism.
ADHD is one of the most commonly diagnosed-and widely misunderstood-neurological conditions in the world today, affecting nearly 10% of kids and a rising number of adults. But what if having an ADHD brain is actually an asset? A growing number of innovators, entrepreneurs, CEO's, Olympic athletes, and award-winning artists have gone public about their diagnosis, saying that their ADHD, managed effectively, has played a vital role in their success. The Disruptors hears from many of those game-changing people speaking candidly about their ADHD, and intimately takes viewers inside a number of families as they navigate the challenges, and the surprising triumphs, of living with ADHD. The Disruptors takes an immersive look at our approach to ADHD that debunks the most harmful myths, and examines the flip side of this trait that ultimately offers a revelatory understanding of the diagnosis, and real hope for millions of kids, families and adults with ADHD.
One entry in a series of films produced to make science accessible to the masses—especially children—this film describes the sun in scientific but entertaining terms.
Melvin and Buddy are two space-exploring pups on a mission. Scarfing down facts like dog biscuits is their plan, but they can't learn about all the topics that interest them without some help. That's where Professor Brain comes in. He's the T-Rex with the mega brain-flex. Climb aboard for all the intergalactic fact-finding fun.
On April 18, 1955, the pathologist performing the autopsy on Albert Einstein covertly steals the genius's brain, hoping to uncover the secret of brilliance. His good intentions and scientific ambitions collide with harsh realities as his world crumbles.
When Harvard PhD student Jennifer Brea is struck down at 28 by a fever that leaves her bedridden, doctors tell her it’s "all in her head." Determined to live, she sets out on a virtual journey to document her story—and four other families' stories—fighting a disease medicine forgot.
When the Tanana River bridge was installed in Salcha, Alaska, the community worried about the levee's effects on fish wildlife. Salcha Elementary School, along with the help of Tanana Valley Watershed Association, conducted a 10-year scientific project with students to study the effects the levee had on Piledriver Slough. Tori Brannan - the filmmaker's mother - is a retired principal at Salcha Elementary and was the project's centerpiece. She shares her experiences with the project, the community, and how her daughter's involvement strengthened their relationship.
Many geneticists and archaeologists have long surmised that human life began in Africa. Dr. Spencer Wells, one of a group of scientists studying the origin of human life, offers evidence and theories to support such a thesis in this PBS special. He claims that Africa was populated by only a few thousand people that some deserted their homeland in a conquest that has resulted in global domination.
Bill Nye is retiring his kid show act in a bid to become more like his late professor, astronomer Carl Sagan. Sagan dreamed of launching a spacecraft that could revolutionize interplanetary exploration. Bill sets out to accomplish Sagan's mission, but he is pulled away when he is challenged by evolution and climate change contrarians to defend the scientific consensus. Can Bill show the world why science matters in a culture increasingly indifferent to evidence?
A unique project, the popular science series "Bread" is shooting around the world, interviews with scientists and world-class experts. There are 4 series in the project: "Immortality", "Money", "Hunger" and "Gene". This is a story about how bread controlled the destinies of continents and empires, how the rise of some civilizations and the fall of others depended on it, how in different countries and at different times it performed the function of money. This is the first time such a complete study of bread and grain is being carried out on a television screen. The focus is on the most interesting events in the history of Russia, Italy, France, Germany, England, China, Egypt and other countries.
A fascinating new look at the biblical, historical, and scientific evidence for Creation and the Flood. Learn from more than a dozen scientists and scholars as they explore the world around us in light of Genesis. Dr. Del Tackett, creator of The Truth Project, hikes through canyons, climbs up mountains, and dives below the sea in an exploration of two competing views... one compelling truth.
Each day, some 2.5 trillion bytes of data are exchanged, a deluge known as "big data." How can we classify, store, and give meaning to this mass of digital information? Will our digital society remain capable of producing a lasting memory? Learn the fate of memory storage in the future.
Is nuclear energy the solution to the climate crisis? Whether it is the only carbon-neutral technology capable of tackling the crisis or a fatally convenient stopgap, time is running out.
A documentary produced in 1979 to celebrate the centenary of the birth of Albert Einstein. Narrated and hosted by Peter Ustinov and written by Nigel Calder.
Earth teems with a staggering variety of animals, including 9,000 kinds of birds, 28,000 types of fish, and more than 350,000 species of beetles. What explains this explosion of living creatures—1.4 million different species discovered so far, with perhaps another 50 million to go? The source of life's endless forms was a profound mystery until Charles Darwin brought forth his revolutionary idea of natural selection. But Darwin's radical insights raised as many questions as they answered. What actually drives evolution and turns one species into another? To what degree do different animals rely on the same genetic toolkit? And how did we evolve?
If machines can be smarter than people, is humanity really anything special?
Explains that heat is really a form of motion, a form of kinetic energy and that it can be converted to other forms of energy and transferred through conduction, convection and radiation. Shows practical examples in which heat preserves lives and makes daily living more convenient.
