01. My Pet Dinosaur

2007-03-13

What if dinosaurs were still alive today? Would we hunt them, farm them - or even keep them as pets? It's a palaeontologist's dream: the chance to live in a world where dinosaurs are not something to be dug out of the ground but are living among us. It may sound far-fetched but dinosaurs were actually rather unlucky. The meteorite impact that doomed them to extinction was an event with a probability of millions to one. What if the meteorite had missed? Had dinosaurs survived, the world today would be very different. If humans managed to survive alongside them, we wouldn't have the company of most, if not all, of the mammals with which we are familiar today. Giraffes, elephants and other mammals wouldn't have had space to evolve. Would we be hunting Hadrosaurs instead of elk? Or farming Protoceratops instead of pigs? Would dinosaurs be kept as pets? And could the brighter dinosaurs have evolved into something humanoid?

02. The Elephant's Guide to Sex

2007-03-20

How do you save an endangered species? Get the animals in the mood for love. Thomas Hildebrandt possesses one of the world's most extraordinary jobs - getting the planet's endangered animals in the mood for love. The planet's creatures are facing the biggest mass extinction since the dinosaurs were wiped out. Species are currently disappearing at up to 10,000 times the natural rate. Coming to the rescue are men like Dr Hildebrandt and his team. They are world leaders in the art of animal manipulation. The billions of pounds spent benefiting human reproduction are now being applied to save endangered species. Techniques such as artificial insemination and IVF have been crucial to the successes in breeding giant pandas, big cats and other mammals in zoos across the world. As Thomas Hildebrandt says "Man has created this annihilation of species. It's up to man to use his ingenuity to save them."

03. Prof Regan's Beauty Parlour

2007-03-27

Professor Lesley Regan is on a mission to fill her bathroom cabinet with cosmetics that actually work. Professor Lesley Regan, one of the UK's most well-respected (and glamorous) medical experts, turns her scientific eye on the world of cosmetics. She's just turned 50, and is out to create an experimentally proven beauty cabinet. Unafraid to examine the wrinkles, age spots and broken veins on her own face, Professor Regan explores just what makes us look old, and if we can slow down the ageing process. The extraordinary world of cosmetic testing is revealed, from the British hair lab which makes New York tap water, to the volunteers sun-bathing for science. Sun damage, cellulite and balding all face Professor Regan's scrutiny as she discovers which cosmetics do - and don't - have the scientific evidence to back up their claims.

04. Mad but Glad

2007-04-03

Pianist Nick van Bloss has Tourette's syndrome. Is his illness a blessing or a curse? Is there really such a thing as the mad genius? Can an illness be both a blessing and a curse? At seven years old, Nick van Bloss started shaking his head, grinding his teeth and making wild whooping noises. Nick had Tourette's syndrome. No medical intervention helped him. But one activity stopped it all... The moment Nick placed his hands on the piano keys his symptoms vanished. By the age of 20, he was an award winning international pianist. He felt sure that his illness had made him the success he was. But there is a catch. The brain state necessary for his genius can also be dangerously close to mental chaos.

05. Moon for Sale

2007-04-10

After 40 years, man is preparing to return to the Moon. But this time the astronauts won't just land on the Moon - they plan to stay. From his office in Nevada, Dennis Hope has spawned a multi-million dollar business selling lunar real estate. But scientists believe the real prize is trapped in the Moon's rocks. It contains large deposits of an extremely rare gas called Helium-3. Could Helium-3 be mined and used as a new source of almost inexhaustible, clean and pollution-free energy on Earth? Whoever succeeds in transporting Helium-3 back to Earth could solve the world's energy crisis. Who will win what has been dubbed the second Moon race? And should we be exploiting the Moon's valuable resources at all?

06. Battle of the Brains

2007-04-17

Seven high-flyers are put through a series of tests to measure their intelligence Can you think of 100 different uses for a sock? How would you cope with glasses that turn everything upside down? What's your emotional intelligence? Can you create a work of art in ten minutes? Horizon takes seven people who are some of the highest flyers in their field - a musical prodigy, a quantum physicist, an artist, a dramatist, an RAF fighter pilot, a chess grandmaster and a Wall Street trader. Each is put through a series of tests to discover who is the most intelligent? The principle way that we measure intelligence, the IQ test, remains popular and convenient. Yet most psychologists agree that it only tells half the story... at most. Where they disagree is how to measure intelligence, for the simple reason that the experts still don't know exactly what it is.

07. Skyscraper Fire Fighters

2007-04-24

Could Professor Jose Torero's fire protection system have saved the Twin Towers? When a fire gets out of control in a skyscraper it tests fire fighters to their limits. Predicting how a fire is behaving high up in a building is almost impossible. The fire fighters who entered the Twin Towers on 11 September 2001 could only guess at what was happening almost 1000 feet above them. That fateful day brought about the death of 343 New York fire fighters. Jose Torero believes fire fighters need not be put in such danger and that new technology could have saved many of the 343 fire fighters who died doing their duty that day. He believes he could even have saved the Twin Towers. He has spent the last ten years developing a system that could change the way fires are fought forever. It's called Firegrid. It's a revolutionary approach to fire fighting that could save thousands of lives, giving man the upper hand on one of his oldest enemies.

08. The Six Billion Dollar Experiment

2007-05-01

Will the Large Hadron Collider finally reveal the elusive God particle? In the coming months the most complex scientific instrument ever built will be switched on. The Large Hadron Collider promises to recreate the conditions right after the Big Bang. By revisiting the beginning of time, scientists hope to unravel some of the deepest secrets of our Universe. Within these first few moments the building blocks of the Universe were created. The search for these fundamental particles has occupied scientists for decades but there remains one particle that has stubbornly refused to appear in any experiment. The Higgs Boson is so crucial to our understanding of the Universe that it has been dubbed the God particle. It explains how fundamental particles acquire mass, or as one scientist plainly states: "It is what makes stuff stuff..."

09. How to Commit the Perfect Murder

2007-05-08

Is it possible to use a knowledge of forensic science, not to catch a killer, but to commit a perfect murder? Modern forensic science should make it impossible to commit murder and get away with it. But how easy would it be to outfox the detectives? With the help of top forensic scientists, and real-life murder investigations, we explore whether it's possible to commit a perfect murder. The body is the most important piece of evidence in any murder. Pathologist Dr Richard Shepherd reveals the crucial clues that give away the secrets of a suspicious death. Dr Lee Goff can work out a time of death from just a few maggots on a corpse. To really understand the way a human decomposes he relies on experiments - and dead pigs make ideal human models. And what is the perfect murder weapon? Probably Agatha Christie's favourite - poison. It leaves no marks on the body, and the victim may not even realise what has happened until it's too late. But there still might not be a perfect murder. The world's most notorious poisoner - Harold Shipman - was eventually caught.
