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...

Autopsy: Emergency Room Massive Blood Loss

Broadcast (2007) In this new three part series, von Hagens explores the impact that accidents and assaults have on the human body, while also demonstrating what first-aiders, paramedics and physicians can do to try to preserve life. First, he dissected human bodies to show how they work; then he did it to show how humans die. Now, Dr Gunther von Hagens, together with the British Red Cross, demonstrates how to save...

Light Darkness and Colours

Using Goethe's Theory of Colours (Zur Farbenlehre) as point of departure, Light Darkness and Colours takes us on a fascinating journey through the universe of colours. In 1704, Sir Isaac Newton published *Light and Refraction*, his study of the interactions between sunlight and prisms. Newton was, as a good scientist, intent on achieving objectivity, which meant studying sunlight in isolation. He thought colours were contained solely in light, and found the spectrum he was looking for. When he reproduced this experiment, Goethe found another, hidden set of colours missed by Newton. Goethe...

Mapping Stem Cell Research: Terra Incognita

Stem Cell Research is arguably the most important research being done today that will pave the way for finding a cure for human’s weaknesses. Cancer, AIDS, degenerative diseases, etc. In 2001, Dr Jack Kessler witnessed a terrible tragedy to his family. This is the story of stem cell research – and Dr. Kessler. At the same time that he became the chair of Northwestern University’s Neurology dept, his daughter, 15 years of age, sufered a ski trip that resulted in paralysis. Dr. Kessler immediately shifted his research from finding a cure for diabetes to finding a cure with stem cell...

What is the Higgs Boson?

Scientists behind Sixty Symbols (Ed Copeland, Roger Bowley and Tony Padilla from the University of Nottingham) are doing their best to answer what actually is the Higgs Boson. Named after Peter Higgs, an Edinburgh University physicist, the Higgs boson is crucial to understanding the origin of mass. The Higgs boson is a hypothetical elementary particle predicted by the Standard Model of particle physics. It belongs to a class of particles known as bosons, characterized by an integer value of their spin quantum number. The Higgs field is a quantum field with a non-zero value that fills...

The Extraordinary Genius of Albert Einstein

The Theory of Special Relativity as part of the educational process: not for the sake of understanding the theory itself, but in using Einstein’s particular discovery as a case study to demonstrate and walk people through real human thinking. The presentation ends with reflecting on the principle of relativity in terms of social relations and individual identities or thought processes, asking the question –how was Einstein able to make his...

Where Did We Come From

Journey back in time to the birth of our solar system to examine whether the key to our planet’s existence might have been the explosive shockwave of an ancient supernova. Meet a chemist who has yielded a new kind of “recipe” for natural processes to assemble and create the building blocks of life. And see how the head louse, a creepy critter that’s been sucking our blood for millions of years, is offering clues about our evolution. Finally, meet neuroscientist André Fenton, who is looking into erasing painful memories with an...

The Link: Uncovering Our Earliest Ancestor

Uncovering Our Earliest Ancestor: The Link, tells the story of an important scientific development that could tell us more about where we come from. The fossil, known as Ida, could be an indication of one of the roots of anthropoid evolution -- the point at which our primate ancestors began first developing the features that would evolve into our own. Is David Attenborough set to reveal the Missing Link in human evolution? The BBC has made an extraordinary new documentary, presented by Sir David Attenborough, which will reveal the discovery of a fossilised skeleton that may be a...

Who’s Afraid of a Big Black Hole

Black holes are one of the most destructive forces in the universe, capable of tearing a planet apart and swallowing an entire star. Yet scientists now believe they could hold the key to answering the ultimate question – what was there before the Big Bang? The trouble is that researching them is next to impossible. Black holes are by definition invisible and there’s no scientific theory able to explain them. Despite these obvious obstacles, Horizon meets the astronomers attempting to image a black hole for the very first time and the theoretical physicists getting ever closer to...
