The Battle of the Sexes

If you thought that women's liberation had ended the arguments, forget it. Ever since anyone can remember, men and women have been at each other's throats. But are the sexes basically the same underneath; or are there really fundamental differences between us? With the men led by Stuart Hall and the women under Faith Brown's guidance, Q.E.D. decided to find out - by making the sexes fight it out in a series of special games, designed to test all kinds of abilities. The psychologists reckon they know who will win what; but will they be proved right? If you want to find out if yours is the superior sex - join the fun and the heat of the battle; and see how comfortably you can accept the revealing results.

The hybrid creature survived for over a week. Dr White now believes that the next 50 years will see the first human body transplants.

Racing with the Sun

Forget the turbochargers; leave the normally aspirated cars at home. For this race, you couldn't even use petrol. To get from Darwin to Adelaide, across the sun-baked interior of Australia, the rules said you had to rely on whatever energy was freely available. The hippies from Hawaii expected wind as well as sun, while the most sophisticated car had an armadillo's coat of gallium arsenide. The competition was fierce but friendly, the journey full of unexpected trials and tribulations. But everyone enjoyed racing with the sun.

The Riddle of the Turin Shroud

A programme from the BBC's factual series Q.E.D. which looked at the background to the famous Shroud of Turin. The programme interviewed doctors and scientists who both supported and were opposed to claims that the Shroud was the burial cloth of Christ. The programme followed up an earlier 1982 programme by examining the results of Carbon 14 testing of the Shroud and other tests that had been made on it to verify that it was a medieval forgery. It was narrated by Professor Anthony Clare.

The Morgan Treatment

Weightlifter David Morgan , Commonwealth Champion and record holder, was as keen as anyone for his brother Tony to try to follow in his footsteps; not just for the fame and glory, but because he had a hunch it might help cure a problem. Tony suffered from epilepsy. Weightlifting has changed Tony's life. His athletic career took off and he became the youngest British champion ever. And at the same time the number of epileptic fits decreased steadily. Tony has now not had any since 1985. Q.E.D. sought specialist help to try to discover whether weightlifting could really be responsible for keeping his epilepsy under control.

Simon's Triumph

Q.E.D.'s latest look at the life of a Falklands soldier. Simon Weston 's war was over when the Argentinian bombs struck the Sir Galahad. He had been burnt over 46 per cent of his body. He was terribly scarred but his own personal war against his injuries had only just begun. Simon's initial struggle was charted in two award-winning Q.E.D. films, Simon's War and Simon 's Peace. Now, filmed over the last three years, Simon's Triumph marks the emergence of a very different character, who no longer looks back. 'I am no war hero,' he says. 'I'm just Simon Weston , scars and all.'

The Write Stuff

You can pick a good astronaut, they say, by knowing 'the right stuff when you see it. But can you pick a top executive just as surely by merely studying his writing? More and more British firms are using graphology secretly to help them select their managers; yet many scientists would say that this art of interpreting handwriting is about as sensible as reading tea leaves. Q.E.D. ran a special series of tests to find out the truth. Should your future career depend on how you dot the 'i's and cross the 't's?

Keyhole Surgery

'You can imagine you're an underwater explorer wandering through reefs of red seaweed.' But you're not - you're an orthopaedic surgeon repairing a torn cartilage. Surgery has changed direction. With the help of the magical telescope, x-rays and ultrasound, 'keyhole surgery' are no longer dirty words but a highly desirable goal.

A Case of Spontaneous Human Combustion?

Is it possible for a person to burst into flames and be reduced to ashes without sign of struggle or panic and without damaging any of the surrounding materials? Could there be some chemical or electrical imbalance in the body which leads to a kind of spontaneous combustion? But if the fire does not start inside the body, how can traditional science explain away the development of a blaze hot enough to reduce bone to ash without damaging a house? Q.E.D. meets firemen and police officers who have discovered the bizarre remains after these puzzling deaths; and scientists who attempt to set up experiments that might explain the phenomenon.
