The Divided Brain

Together to Mars?

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.

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.

In today's climate debate, there is only one factor that cannot be calculated in climate models - humans. How can we nevertheless understand our role in the climate system and manage the crisis? Climate change is a complex global problem. Increasingly extreme weather events, rising sea levels, and more difficult living conditions - including for us humans - are already the order of the day. Global society has never faced such a complex challenge. For young people in particular, the frightening climate scenarios will be a reality in the future. For the global south, it is already today. To overcome this crisis, different perspectives are needed. "THE UNPREDICTABLE FACTOR" goes back to the origins of the German environmental movement, accompanies today's activists in the Rhineland in their fight against the coal industry and gives a voice to scientists from climate research, ethnology and psychology.

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?

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.

A documentary examining what the Tyrannosaurus Rex was really like - both appearance and behaviour - using the recent palaeontological and zoological research.

Becoming a father is an extraordinary adventure in a man's life, but it is also a real physiological metamorphosis that science is only just beginning to reveal. Researchers from multiple disciplines are lifting the veil on these changes taking place in men who are in contact with young children, and their discoveries are astonishing. By tracing the thread of evolution, the film reveals that these deep, long-ignored bonds between men and children are very ancient. And that they are just waiting for the right context to fully express themselves.

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.

Short educational film of our solar system

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.

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.

Explores the latest longevity research and whether dramatically extended human lifespan is achievable. Features top scientists, startup leaders, celebrities, and critics offering balanced perspectives on this fascinating field.

It all started with a simple question: Is it possible to travel to the oldest and newest places on Earth? YouTuber, author and filmmaker Joe Scott looked into it, and it turned into the trip of a lifetime. It's a journey across 4 billion years of geologic history that explores the past and present of our remarkable planet, the absurd immensity of deep time, and our tiny but important place in it.

What forms might life take in the Solar System and beyond? In the Academy's newest original planetarium show, see how a deeper understanding of Earth might help us locate other living worlds, light years away.

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.

A team of international skiers embark on a two-week glacier traverse connecting two remote research stations in Kazakhstan. The Tien Shan's 4000+ meter peaks host an active scientific community, leveraging the rare environmental conditions for groundbreaking research. Established during the Soviet Union's occupation, the high-altitude research stations here are home to some of the longest-standing glacier and cosmic radiation experiments in the world - and are surrounded by deadly alpine terrain.

The discovery of neuroplasticity, the fact that thoughts can change the structure and function of our brains, even into old age, is one of the most important breakthroughs in our understanding of the brain in recent times. In The Brain That Changes Itself, Dr Norman Doidge explores the profound implications of the changing brain in a way that will permanently alter the way we look at human possibility and human nature. The documentary examines a blind man who sinks a basketball; a woman with half a brain who leads a normal life; learning disorders, strokes and brain traumas that are improved and cured; and chronic pain that is alleviated. The vast expanse of the brain's possibility is still unrealized.

An accomplished molecular biologist moves out of the lab in a quest to make an encyclopedia documenting all the fruit fly species in North America.

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'
