Horizon: Which Universe Are We In?

The recent discovery by the Kepler satellite of thousands of Earth-like planets where life could be possible, has given a big boost to the Search for Extraterrestrial Intelligence (SETI). In 2011, for the first time ever, Kepler provided us with a census of the Milky Way. We can now calculate how many stars in the Milky Way could have a planet like ours: around a billion.

This shows physicist Stephen Hawking's life as he deals with the ALS that renders him immobile and unable to speak without the use of a computer. Hawking's friends, family, classmates, and peers are interviewed not only about his theories but the man himself.

A crash course in the professional and scientific work related to the field of venomous herpetology. The film covers diverse topics, including biochemistry, biology, law and public policy, conservation, venom collection, animal husbandry, antivenom production, emergency medicine, veterinary medicine, toxicology and toxinology. The film follows the personal and working lives of prominent experts in the field, beginning with their childhood interest through their professional careers, with particular emphasis on the sciences related to their work.

Near the cold Pyrenees of Iberia, surrounded by ancient and dark green forests, lies a strange land where the rain is scarce and the wind is always blowing. The soil is poor, there are no trees and the landscape resembles the moon. Is this what the future of desertification will look like? Incredible creatures with surprising behavior live in this strange landscape. The documentary explores a place with very dry skin but a wet hidden heart where even waterfowl or amphibians can live. Living in such conditions is not easy and only the toughest animals will survive.

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.

There’s something very odd going on in space – something that shouldn’t be possible. It is as though vast swathes of the universe are being hoovered up by a vast and unseen celestial vacuum cleaner. Sasha Kaslinsky, the scientist who discovered the phenomenon, is understandably nervous: ‘It left us quite unsettled and jittery’ he says, ‘because this is not something we planned to find’. The accidental discovery of what is ominously being called ‘dark flow’ not only has implications for the destinies of large numbers of galaxies – it also means that large numbers of scientists might have to find a new way of understanding the universe. Dark flow is the latest in a long line of phenomena that have threatened to re-write the textbooks. Does it herald a new era of understanding, or does it simply mean that everything we know about the universe is wrong? .

Oil is a primary energy source in the world. Global oil consumption reached approximately 95 million barrels per day but oil fields' quality is constantly declining. A team of Russian scientists came up with more accurate, cheaper, and faster technology that can increase the oil production rate. After all, modern civilization is built in the way that 'to live well' means 'consume more oil'

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.

In this fascinating sequel to "Is Genesis History?", watch a team of scientists discover new evidence for the global Flood. By the time the journey is over, you'll understand exactly how modern science connects to the book of Genesis.

A team of international scientists attempt to document the first-ever image of a black hole.

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.

In a world where 92 million Americans rely on statins as their lifeline, one man's unexpected health journey uncovers a medical mystery that could upend everything we think we know about heart health, cholesterol, and the ketogenic diet.

In this educational film, laboratory demonstrations show the effects of moisture and temperature on the growth of molds. Photomicrography reveals the structure of molds: hyphae, mycelium, spore balls, spores. Beginning with spores on a rice culture, time-lapse photography shows the formation of a new colony.

Explore the secrets of the universe with Professor Brian Cox in this special event that combines ground-breaking science with the power of the Sydney Symphony Orchestra.

Are we becoming Plastic People? Our ground-breaking feature documentary investigates our addiction to plastic and the growing threat of microplastics on human health. Almost every bit of plastic ever made ends up ground down into "microplastics". These microscopic particles drift in the air, float in the water and sit in the soil. And now, leading scientists are finding them in our bodies: organs, blood, brain tissue and even the placentas of new mothers. What is the impact of these invisible invaders on our health? Ziya Tong, author and science journalist, makes it personal by visiting leading scientists and undergoing experiments in her home, on her food, and on her body.

A documentary chronicling the history of the telescope from the time of Galileo. Featuring interviews with leading scientists discussing Galileo's first use of the telescope to the latest discoveries in cosmology.

CERN and the University of California-Santa Barbara are collaborating in the search for the elusive substance that physicists and astronomers believe holds the universe together -- dark matter. Where is this search now in the realm of particle physics and what comes next?

With a wealth of fantastic archive footage and a series of revealing interviews with those who had first-hand experience, filmmaker Vicki Lesley tells the turbulent story of the West’s love-hate relationship with a nuclear power over the past seventy years. Capturing both the tantalising promise and the repeated disappointments of this singular technology, the film reveals how the post-war, romantic fantasy of an Atom-powered future developed into the stormy, on-off relationship still playing out today.
