The Boy Who Was Turned Into a Girl

In 1965 in the Canadian town of Winnipeg, Janet Reimer gave birth to twin boys - Bruce and Brian. Six months later a bungled circumcision left Bruce without a penis. Based on a radical new theory of gender development the decision was taken to raise Bruce as a girl. In 1967 Bruce became Brenda and for the next three decades this case would be at the heart of one of the most controversial theories in the history of science. The man behind this work was world-renowned psychologist Dr John Money. In the 1950s Dr Money developed a theory that revolutionised our understanding of gender. Money...

The Brain: A Secret History

In a compelling and at times disturbing series, Dr Michael Mosley explores the brutal history of experimental psychology. Mosley embarks on three journeys to understand science’s last great frontier – the human mind – as he traces the history of the attempts to understand and manipulate the brain. Experiments on the human mind have led to profound insights into how our brain works – but have also involved great cruelty and posed some terrible ethical dilemmas. Mind Control. To begin, Michael traces the sinister ways this science has been used to try to control our minds. He...

The Core

For centuries we have dreamt of reaching the center of the Earth. Now scientists are uncovering a bizarre and alien world that lies 4,000 miles beneath our feet, unlike anything we know on the surface. It is a planet buried within the planet we know, where storms rage within a sea of white-hot metal and a giant forest of crystals make up a metal core the size of the Moon. Horizon follows scientists who are conducting experiments to recreate this core within their own laboratories, with surprising...

The Cove

The Cove begins in Taiji, Japan, where former dolphin trainer Ric O’Barry has come to set things right after a long search for redemption.

One fateful day, a heartbroken Barry came to realize that these deeply sensitive, highly...

The Creative Brain How Insight Works

It is a feeling we all know, the moment when a light goes on in your head. In a sudden flash of inspiration, a new idea is born. Today, scientists are using some unusual techniques to try to work out how these moments of creativity - whether big, small or life-changing - come about. They have devised a series of puzzles and brainteasers to draw out our creative behavior, while the very latest neuroimaging technology means researchers can actually peer inside our brains and witness the creative spark as it happens. What they are discovering could have the power to make every one of us more...

The Dark Secret Of Hendrik Schön

Imagine a world where disease could be eradicated by an injection of tiny robots the size of molecules. That is the hope offered by nanotechnology - the science of microscopically small machines. But others fear nanotechnology could lead to a non-biological cancer - where swarms of tiny nanobots come together and literally devour human flesh. Sounds like science fiction? It certainly did until a brilliant young scientist called Hendrik Schön seemed to bring it a step closer. Schön's great breakthrough was to make a computer transistor out of a single organic molecule. It was an...

The Day We Learned to Think

Understanding of humans' earliest past often comes from studying fossils. They tell us much of what we know about the people who lived before us. There is one thing fossils cannot tell us; at what point did we stop living day-to-day and start to think symbolically, to represent ideas about our environment and how we could change it? At a dig in South Africa the discovery of a small piece of ochre pigment, 70,000 years old, has raised some very interesting questions. Anatomically modern humans (Homo sapiens) emerged in Africa roughly 100,000 years ago. We know from...

The Deep Earth

Broadcast (1998) A curious feature of our planet’s surface is that it has two distinct levels: the dry land on the continents, on average a few hundred metres above sea level, and the ocean floor, making up two thirds of the Earth’s surface, several kilometres below sea level. Only in the past fifty years have scientists begun to explore in detail this vast region, revealing beneath the waves a landscape quite unlike the world we are used to. They have discovered a vast mountain range which encircles the entire globe where new sea floor is being continuously...
