For generations, we have believed that man is driven by ruthless self-interest. But over the past decade, this idea has been increasingly challenged. New research from fields as diverse as political science, psychology, sociology and experimental economics is forcing us to rethink human actions and motivation. ‘The Altruism Revolution’ examines the scientific reasons behind the call for a more caring society.

Artists Peter Fischli and David Weiss create the ultimate Rube Goldberg machine. The pair used found objects to construct a complex, interdependent contraption in an empty warehouse. When set in motion, a domino-like chain reaction ripples through the complex of imaginative devices. Fire, water, the laws of gravity, and chemistry determine the life-cycle of the objects. The process reveals a story concerning cause and effect, mechanism and art, and improbability and precision, in an extended science project that will mesmerize the mind.

Morgan Spurlock subjects himself to a diet based only on McDonald's fast food three times a day for thirty days without exercising to try to prove why so many Americans are fat or obese. He submits himself to a complete check-up by three doctors, comparing his weight along the way, resulting in a scary conclusion.

An experimental project made up of 10 minute silent portraits with 60+ participants.

Professor Jim Al-Khalili investigates the amazing science of gravity. As well sculpting our universe, gravity also affects our weight, height and even the rate at which we age.

The Stanford prison experiment was a landmark psychological study of the human response to captivity, in particular, to the real world circumstances of prison life, and the effects of imposed social roles on behaviour. It was conducted in 1971 by a team of researchers led by Philip Zimbardo of Stanford University.

In a society where "celebutantes" like Paris Hilton dominate newsstands and models who weigh less than 90 pounds die from malnutrition, female body image is one of the more dire problems facing today's society. "America the Beautiful" illuminates the issue by covering every base. Child models, plastic surgery, celebrity worship, airbrushed advertising, dangerous cosmetics - no rock is left unturned.

This story follows one man's quest to uncover the origins and reveal the mysteries of a possible Holocaust artifact some historians now say never existed: lampshades made of human skin. When the flood waters of Hurricane Katrina receded, they left behind a wrecked New Orleans and a strange looking lamp that an illicit dealer claimed was 'made from the skin of Jews.'

"The Last Dragon" is a nature mockumentary about a British scientific team that attempts to understand the unique incredible beasts that have fascinated people for ages. CGI is used to create the dragons.

Werner Boote presents an up-close and personal view of the controversial and fascinating material that has found its way into every facet of our daily lives: plastic. He takes us on a journey around the globe, showing that plastics have become a threat for both environment and human health.

People looking at the Mona Lisa in the Louvre – or are they just looking at themselves?

99% of the plastic that should be floating in the oceans is missing. Even accounting for the plastic that washes up on beaches or is trapped in arctic ice, millions of tonnes has simply disappeared. As most plastic never deteriorates, it simply breaks down into smaller and smaller particles that are invisible to the human eye, what happens to this missing ocean plastic is a mystery. In this investigation, scientists embark in search of the micro-plastics. Small, mostly invisible, toxic, they are home to the new ecosystem: the plastisphere. But where are they? Ingested by organisms? Buried under the ocean floor? Degraded by bacteria? And what is the impact of them entering the food chain?

Children play amidst cycles of thunder and violence.

Comedians James Acaster, Guz Khan and Alex Brooker have all been obsessed with the classic 1990 comedy "Home Alone" ever since they were kids.
