A documentary on Al Gore's campaign to make the issue of global warming a recognized problem worldwide.

Sniper: Bulletproof deconstructs and analyzes the little-known sniper events that have occurred when no other course of action was possible. The people who planned the takedowns, or pulled the trigger, share their techniques and bring to light the many factors that had to be considered in each mission: terrain, wind speed, temperature, elevation changes... all are critical to taking out targets considered bulletproof. A sniper has one chance, one breath, to rise to the occasion and save the day... if they miss, there may never be another opportunity. As these never told before stories unfold, the viewer also learns about the high-tech gear each sniper carries on their classified missions.

Let There Be Light follows the story of dedicated scientists working to build a small sun on Earth, which would unleash perpetual, cheap, clean energy for mankind. After decades of failed attempts, a massive push is now underway to crack the holy grail of energy.

Trees talk, know family ties and care for their young? Is this too fantastic to be true? German forester Peter Wohlleben and scientist Suzanne Simard have been observing and investigating the communication between trees over decades. And their findings are most astounding.

In Astronomy Part 2, you will learn all about the planets, asteroids, comets, meteoroids, the layers of the sun, fusion, and more. The Standard Deviants make learning astronomy easier with their unique teaching style, which incorporates humor, mnemonics, and sophisticated computer graphics.

This film consists of three parts. The first dramatizes the life of the founder of Soviet astronautics, Konstantin Tsiolkovsky; the second describes the development of rocket technology; and the third visualizes the future with enactments of the first manned spaceflight, spacewalk, space station construction and humans on the moon.

For the past 20 years, the world has seen an alarming decrease in IQ and a rise of autism and behavioral disorders. This international scientific investigation reveals how chemicals in objects surrounding us affect our brain, and especially those of fetuses.

Most people fully accept paranormal and pseudoscientific claims without critique as they are promoted by the mass media. Here Be Dragons offers a toolbox for recognizing and understanding the dangers of pseudoscience, and appreciation for the reality-based benefits offered by real science.

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.

When the U.S. trade embargo left Cuba isolated from medical resources, Cuban scientists were forced to get creative. Now they've developed lung cancer vaccines that show so much promise, some Americans are defying the embargo and traveling to Cuba for treatment. In an unprecedented move, Cuban researchers are working with U.S. partners to make the medicines more widely available.

William Shatner sits down with scientists, innovators and celebrities to discuss how the optimism of 'Star Trek' influenced multiple generations.

The Dream Is Alive takes you into space alongside the astronauts on the space shuttle. Share with them the delights of zero gravity while working, eating and sleeping in orbit around the Earth. Float as never before over the towering Andes, the boot of Italy, Egypt and the Nile. Witness firsthand a tension-filled satellite capture and repair and the historic first spacewalk by an American woman.

In 1858 Charles Darwin struggles to publish one of the most controversial scientific theories ever conceived, while he and his wife Emma confront family tragedy.

William Shatner presents a light-hearted look at how the "Star Trek" TV series have influenced and inspired today's technologies, including: cell phones, medical imaging, computers and software, SETI, MP3 players and iPods, virtual reality, and spaceship propulsion.

An award-winning feature-length creative documentary exploring the extraordinary world of the plasmodial slime mould through the eyes of the fringe scientists, mycologists and artists. In recent years this curious organism has become the focus of much research in such areas as biological-inspired design, emergence theory, unconventional computing and robot engineering.

Darwin's great insight – that life has evolved over millions of years by natural selection – has been the cornerstone of all David Attenborough’s natural history series. In this documentary, he takes us on a deeply personal journey which reflects his own life and the way he came to understand Darwin’s theory.

In this two-part Channel 4 series, Professor Richard Dawkins challenges what he describes as 'a process of non-thinking called faith'. He describes his astonishment that, at the start of the 21st century, religious faith is gaining ground in the face of rational, scientific truth. Science, based on scepticism, investigation and evidence, must continuously test its own concepts and claims. Faith, by definition, defies evidence: it is untested and unshakeable, and is therefore in direct contradiction with science. In addition, though religions preach morality, peace and hope, in fact, says Dawkins, they bring intolerance, violence and destruction. The growth of extreme fundamentalism in so many religions across the world not only endangers humanity but, he argues, is in conflict with the trend over thousands of years of history for humanity to progress to become more enlightened and more tolerant.

In The Womb is a 2005 National Geographic Channel documentary that focus on studying and showing the development of the embryo in the uterus. The show makes extensive use of Computer-generated imagery to recreate the real stages of the process.

Dr George McGavin and Dr Zoe Laughlin set up base camp at one of the UK's biggest sewage works to investigate the revolutionary science finding vital renewable resources and undiscovered life in human waste. Teaming up with world-class scientists, they search for biological entities in sewage with potentially lifesaving medical properties, find out how pee can generate electricity, how gas from poo can fuel a car and how nutrients in waste can help solve the soil crisis. They follow each stage of the sewage treatment process, revealing what the stuff we flush can tell us about how we live today, and the mindboggling biotechnology being harnessed to clean it, making the wastewater safe enough to return to the environment.
