Daha Fazla OkuThe Quest for Tannu Tuva
Richard Feynman was not only an iconoclastic and influential theoretical physicist and Nobel laureate but also an explorer at heart. Feynman through video recordings and comments from his friend and drumming partner Ralph Leighton tell the extraordinary story of their enchantment with Tuva, a strange and distant land in the centre of Asia.
While few Westerners knew about Tuva, Feynman discovered its existence from the unique postage stamps issued there in the early 20th century. He was intrigued by the unusual name of its capital, Kyzyl, and resolved to travel to the remote, mountainous land. However, the Soviets, who controlled access, were mistrustful, unconvinced that he was interested only in the scenery. They obstructed his plans throughout 13 years.
The majority of the scenes are extended narratives by Feynman. There is included a delightful extended discussion and demonstration of Feyman's bongo playing. Feynman explains how he used a phrase book of the Tuva language to write and express an interest in visiting there. The proposed trip took years to arrange. The programme never does get to show Feyman in Tuva; he died of abdominal cancer a few days after the recorded interview, at age 69 in February 1988. The story is interspersed with earlier recorded conversations by Feynman that add his perspectives on the nature of physics. So, this is not a travel documentary at all; rather it is another fascinating insight into the exciting personality of Richard Feynman.
"You have no responsibility to live up to what other people think you ought to accomplish." - Richard Feynman (1918-1988).

Daha Fazla OkuIce Mummies: A Life in Ice
In this second part of the Ice Mummies trilogy, attention turns to Ötzi, the Neolithic man plucked with an ice pick and some not inconsiderable brute force from an Alpine glacier. Once again, as with the Ice Maiden, an impressive set of relationships are on display in the vicinity of the leathery character and his bedraggled belongings. By far the most important man in Ötzi's life is Konrad Spindler, whose chance identification of the age of the mummy upon its discovery catapulted him to stardom and a life of analysis and scientific monitoring. Spindler is fiercely defensive of Ötzi, like Frankenstein and his monster, although the relationship is much less emotional than Natalia and her Ice Maiden.
A bewildering array of more minor characters emerge during the course of the film, my particular favourite being a yodeling mountain dweller, included as a representation of how Ötzi has effected the local population. All varieties of archaeological life appear in this film, from Professors zur Nedden and Seidler, whose double act hints at the Muppets Stadtler and Waldorf, to an extra from This is Spinal Tap, Hanspeter Schrattenthaler, whose bare chest and rock star poses suggest he dearly wishes his copper axe were a guitar. Also worthy of mention is the lovable Harm Paulsen, who lives and works in a reconstruction of a Neolithic village and whose lilting Danish tones express some of the more human elements of the sad demise of Ötzi, such as the family he may have left behind, providing a stark contrast to the strictly 'scientific' views of Spindler.

Daha Fazla OkuSaddam's Secrets
After the 1991 Gulf War, a UN Special Commission was set up to go into war-torn Iraq, seek out Saddam Hussein's weapons of mass destruction and destroy or disable them.
This remarkable Horizon follows the tension of the inspectors' every move as they track down secret military bases, Scud missile launchers, the infamous super-gun barrels, decaying chemical weapons dumps, and the remains of the nuclear research establishment, cunningly hidden amongst debris and the innocent-looking rubble of post-war reconstruction. At each stage in the cat-and-mouse game with the Iraqi security forces, the UN team had to draw on cunning and courage to force their way into secret locations.
Day by day, they recorded their progress on video, and charted the tensions of diplomatic stand-offs as the world was twice drawn close to another violent confrontation in the Gulf. The courage of the UN team, drawn from scientists from all over the world, is graphically revealed as they attempt to gauge the lethal nature of rusting canisters of poison gas, at Saddam's decaying chemical weapons store.
After the immediate rush of successes, the inspectors' work became a steady process of attrition - grinding on against the stonewalling of their hosts. "The weapons programme is like layers of an onion. Every now and then, Saddam would allow us to peel one back, but there is always more underneath." But five years on, the inspectors had still not tracked down proof of the darkest of Saddam's secrets: his biological weapons programme. However, painstaking detective work revealed that huge quantities of the media needed for growing biological organisms had been imported, and Iraq finally admitted to having substantial biological weapons, which are cheaper and more simple to produce than nuclear and chemical weapons, yet have the same destructive power.
Gradually the inspectors got close to the labs and animal testing stations where the lethal toxins had been produced. In addition to the most common biological warfare organisms, anthrax and botulinus, Iraq developed and tested strains of viruses never before adopted for weapons purposes. This was part of an ongoing international biological arms race to design novel weapons using gene-splicing or fibroviruses such as Ebola, Hanta fever and others.

Daha Fazla OkuBreath of Life
In this moving film Horizon follows the Loughran family in their fight to save the life of their daughter Sheila who suffers from cystic fibrosis. They lost their youngest daughter Ann to the disease in 1974 at the age of 15, and now as the health of their third daughter Sheila deteriorates, they must face the prospect of losing a second child. The current shortage of donor organs means that Sheila's only hope of survival is a rare and controversial operation that requires her two surviving siblings to undergo an arduous and potentially fatal operation.
An X-ray of Shelia's lungs Cystic fibrosis (CF) is the most common genetic disease in this country and it is incurable. The lungs of people with cystic fibrosis become covered with a sticky mucus making them extremely susceptible to bacterial infection. Over time these infections badly scar the lungs, until eventually they stop functioning. The defective CF gene is harmless when only a single copy of the gene is inherited. However, both the Loughran parents carry the gene, giving any child they may have a 25% chance of being born with cystic fibrosis. In fact two of their four children were born with the condition.
Horizon joins the family at a time when Sheila's health has deteriorated to such an extent that she requires oxygen 24 hours a day and has only months to live. Although on the waiting list for a donor lung, with 50% of patients dying while waiting to receive a transplant, Sheila's chances are not good.
The family has become aware of a controversial new operation, pioneered in the UK by Professor Sir Magdi Yacoub at Harefield Hospital. The technique, known as Living Donor Lung Transplantation, would involve removing Sheila's diseased lungs and, in an extraordinary three-way operation, replacing them with a lobe from one of the lungs of each her two siblings.
There have been six of these groundbreaking operations carried out in this country. However, only three patients have lived longer than a month. There is a clear moral dilemma - with such a low success rate, is it ethical to put the lives of two healthy people at risk? Even if the operation is initially successful it may only give Sheila five more years to live, by which time her new lungs are likely to fail again.
Damian Loughran Sheila's brother and sister, Damian and Josephine, feel compelled to do anything they can to save their dying sister. They undergo stringent tests before being certain that they are compatible donors and fit for surgery. They will have to face the risk of haemorrhaging and infection, both of which could potentially be fatal. After the operation both donors will be left with a 20-25% permanent loss of lung function. Despite these dangers, Damian and Josephine remain determined to proceed.
As all three of their children are wheeled in for the 12-hour operation, Mary and Harry Loughran's emotion is apparent. A day later, Sheila is breathing with her new lungs, but it is not long before complications arise. She is unable to absorb food and develops an abscess on her lung. Sheila is kept under sedation and so is unaware of these complications. Sadly, three weeks after the operation, Sheila loses her fight for life.
Daha Fazla OkuThe Lost City of Nasca
On a barren desert in South America lies one of the greatest archaeological puzzles in the world. Etched in the surface of the desert pampa sand are hundreds of straight lines, geometric shapes and pictures of animals and birds - and their patterns are only clearly visible from the air. They were built by a people called the Nasca - but why and how they created these wonders of the world has defied explanation.
On the pampa, south of the Nasca Lines, archaeologists have now uncovered the lost city of the line-builders, Cahuachi. It was built nearly two thousand years ago and was mysteriously abandoned 500 years later. New discoveries at Cahuachi are at last beginning to give us insight into the Nasca people and to unravel the mystery of the Nasca Lines.
Distorted heads The Lines were first spotted when commercial airlines began flying across the Peruvian desert in the 1920's. Passengers reported seeing 'primitive landing strips' on the ground below. No one knew who had built them or indeed why. Since their discovery, the Nasca Lines have inspired fantastic explanations.
SpiderPerhaps most famously, the Austrian writer Erich von Danikken claimed that they were evidence that the earth had been visited by extra-terrestrials. The lines, he said, were runways for their spacecraft. Scientific study began in the 1940s with the arrival of a German mathematician and astronomer called Maria Reiche. She lived at Nazca until her death in 1998 and was known as the Lady of the Lines. Reiche believed that the lines were a sophisticated astronomical calendar. However, in 1965, astronomer Gerald Hawkins came to Nazca and used computers to check Reiche's theory. Hawkins could find no correlation between the lines and the stars.
Giuseppe Orefici Italian archaeologist Giuseppe Orefici has been excavating the immense Cahuachi site for the last 17 years. Every year he brings a team of specialists to South America for three, intensive months of excavation. Horizon joined Orefici and his team in the hot, windy months of 1998 and this is a fascinating record of their extraordinary finds.
Woven clothCahuachi is emerging as a treasure trove of the Nasca culture. As Orefici and his team excavate, discoveries of paintings on preserved pottery, and the ancient technique of weaving that the Nasca people developed, have given an insight into how the lines may have been made, and what they might have been used for, more than 1500 years ago.
MummyMost exciting is the discovery of human remains. Stunningly preserved in the dry soil of the Peruvian desert are the mummified bodies of the Nasca themselves. Orefici's colleagues Brian Harrison and Andrea Drusini carry out modern autopsies on these remarkable finds, and reveal the strange world and rituals of the Nasca people.
CahuachiOriginally believed to have been a military stronghold, Cahuachi is now reckoned to be a place of ritual and ceremony, and Orefici's stunning new evidence confirms this idea. Cahuachi is now revealed to have been abandoned after a series of natural disasters destroyed the city. But before they left it, the Nasca people covered the city in the arid pampa sand where, until recently, it has remained a barely visible mound in the desert.
Daha Fazla OkuThe Diamond Makers
There is something so special about diamonds, and they are so valuable, that people have always been prepared to go to the most extraordinary lengths to find them. But how would we feel about the uniqueness of diamonds if it was possible to make one in a laboratory, just like the real thing, down to the nearest atom? In the last few years there has been a scientific race to do exactly this: to manufacture the perfect gem diamond.
Today the dream is close to becoming reality. Science has finally found a way to replicate in a few days something that nature has taken millions of years to produce - diamonds. These man-made diamonds are so close to the real thing, that they have the same atomic structure as natural diamonds. Even the most sophisticated machines are finding it hard to tell the difference. More importantly, these diamonds can be made and sold at a profit.
Synthetic diamond press: This is the story of the race to produce man-made gem diamonds, from the first faltering steps 50 years ago, to today's 'New Alchemists' in Russia who are using the latest science and technology to produce perfect synthetic diamonds in an array of colours and sizes. And it is the story of how this leap in diamond-making technology has forced De Beers to develop ever-more sophisticated detection equipment, trying to spot the synthetics, while the physical distinction between real and man-made diamonds becomes more and more blurred.
Today there are alarm bells ringing at De Beers in Johannesburg. De Beers controls the world diamond trade. By buying up most of the world's uncut diamonds, the company can regulate supply to select dealers, increasing it in good years and reducing it in bad, to keep prices high. Every year 3 billion pounds worth of rough diamonds are distributed around the world for cutting and polishing.
The diamond market survives on public confidence. Already De Beers spends a fortune trying to detect synthetic gems, and teach wholesalers and graders what the molecular differences are. But imagine if these synthetics had exactly the same properties as real diamonds, each atom in place, every manufacturing flaw removed, leaving something indistinguishable from the real thing. They would be undetectable. What would a real diamond be then? To many, the difference would be purely psychological. And so what would happen to public confidence in the natural diamond market?
Man made diamonds: According to the new alchemists, this is all just about to happen.
Daha Fazla OkuSupervolcanoes
Hidden deep beneath the Earth's surface lie one of the most destructive and yet least-understood natural phenomena in the world - supervolcanoes. Only a handful exist in the world but when one erupts it will be unlike any volcano we have ever witnessed. The explosion will be heard around the world. The sky will darken, black rain will fall, and the Earth will be plunged into the equivalent of a nuclear winter.
Normal volcanoes are formed by a column of magma - molten rock - rising from deep within the Earth, erupting on the surface, and hardening in layers down the sides. This forms the familiar cone shaped mountain we associate with volcanoes. Supervolcanoes, however, begin life when magma rises from the mantle to create a boiling reservoir in the Earth's crust. This chamber increases to an enormous size, building up colossal pressure until it finally erupts.
The last supervolcano to erupt was Toba 74,000 years ago in Sumatra. Ten thousand times bigger than Mt St Helens, it created a global catastrophe dramatically affecting life on Earth. Scientists know that another one is due - they just don't know when... or where.
Yellowstone National Park: It is little known that lying underneath one of America's areas of outstanding natural beauty - Yellowstone Park - is one of the largest supervolcanoes in the world. Scientists have revealed that it has been on a regular eruption cycle of 600,000 years. The last eruption was 640,000 years ago... so the next is overdue.
And the sleeping giant is breathing: volcanologists have been tracking the movement of magma under the park and have calculated that in parts of Yellowstone the ground has risen over seventy centimetres this century. Is this just the harmless movement of lava, flowing from one part of the reservoir to another? Or does it presage something much more sinister, a pressurised build-up of molten lava?
Scientists have very few answers, but they do know that the impact of a Yellowstone eruption is terrifying to comprehend. Huge areas of the USA would be destroyed, the US economy would probably collapse, and thousands might die.
And it would devastate the planet. Climatologists now know that Toba blasted so much ash and sulphur dioxide into the stratosphere that it blocked out the sun, causing the Earth's temperature to plummet. Some geneticists now believe that this had a catastrophic effect on human life, possibly reducing the population on Earth to just a few thousand people. Mankind was pushed to the edge of extinction... and it could happen again.

When and how did space and time begin? The birth of the Universe is one of the biggest mysteries in astronomy. It has perplexed the best scientific minds for centuries. Decades before space travel was possible, astronomers dreamed of putting a telescope into orbit to try and answer these fundamental questions. It wasn't until the 1970s, when space flight had become a reality, that NASA resolved to build just such a space telescope. They named it Hubble.
This was one of the most ambitious missions ever conceived. The technical challenges were enormous and it took 12 years to design and build. Travelling at seventeen thousand miles an hour, the Hubble Telescope would take pictures of the furthest reaches of space, transmitting them 400 miles back to Earth.
In April 1990 the Hubble Space Telescope was launched. But just weeks later, disaster struck - the $2 billion telescope had a fatal flaw in its main mirror. This was not just a disaster for NASA; it was a national scandal. Hubble had to be saved; scientists and engineers began to search desperately for a solution to the problem.
Plans for an adventurous repair mission began to take shape but it was two years before work could be carried out. It took astronauts five gruelling space-walks to carefully replace the instruments and patch up the telescope. But nobody knew if Hubble would be able to deliver on any of its original promises.
Finally, the miracle happened. An unexpected avalanche of data from Hubble confirmed that the telescope was fixed. At last it began to solve the most fundamental puzzles of the Universe.
Hubble has given us breathtaking images of the birth of stars; it has found black holes swallowing matter at the centre of galaxies; and last year the Hubble Telescope resolved the most fundamental question in astronomy - the age of the Universe. At last, half a century of scientific endeavour was rewarded.
Horizon marks the 10th anniversary of the launch of the Hubble Space Telescope by tracing the extraordinary tale of triumph, disaster and eventual success of this unique window into the Universe.

What happens when a completely healthy person wants their leg amputated?
Gregg is 55 and does not feel physically whole. This is despite the fact that he is physically healthy and able-bodied. Gregg believes he is incomplete with two legs and it has been his life-long struggle to get doctors to agree that removing one of his legs is the right thing for him. He isn't delusional. He knows what he is asking for and knows it is strange. But he cannot help his feelings. Gregg suffers from a rare but genuine psychological disorder - a form of body dysmorphia. And Gregg is not alone.
Although Body Dysmorphia is rare, a worldwide network of sufferers is growing and demanding treatment. It affects both men and women and each person has a precise sense of which limb or limbs they want removed.
Cases were cited a hundred years ago but still very little is known about the disorder. No one knows what causes it and very few psychiatrists have even encountered patients with the disorder. All that the patients seem to have in common is a strong memory of the first amputee they saw. They also report that the feelings started in childhood. However, the profession is now being forced to respond and devise methods of treatment. If not treated, it has been reported that suffers can go to extreme lengths to remove the unwanted limbs themselves. Some have even committed suicide.
The difficulty with the condition is that the conventional methods for treating psychological problems, drugs and therapy, do not seem to be effective. The only treatment that does seem to be effective is surgery - actually removing the limb. The idea of using surgery is highly controversial and has divided the medical community. Some physicians consider it much too drastic a measure, possibly conflicting with their Hippocratic oath, not to cause harm. Others believe that it is the only way to free the patient of their obsession, 'curing' them of their psychological problem.
At the present time, there is only one surgeon in Britain who has been prepared to perform such operations and who has publicly defended his decision. He has operated on two patients, both of who claim to be delighted with their new body-image and now free to get on with the rest of their lives.
There are many other patients who seek similar treatment. Horizon 'Complete Obsession' follows a year in the lives of people who are body dysmorphic and are determined to have their limbs surgically removed. It follows the process they go through to try and achieve their goal.
Daha Fazla OkuIs GM Safe?
Some people see GM food as a ground-breaking scientific idea that could help to end world hunger and reduce global pollution. Others see it purely as 'Frankenstein foods' on 21st century menus, bringing health and environmental disasters. But what are the real scientific facts behind the newspaper headlines?
Scientists can manipulate the genetic code of life to produce plants with new characteristics never seen in nature. They can isolate any one gene from any organism like an animal or bacterium, and insert it into a completely unrelated species like a plant. The possibilities are almost endless - Scientists can insert a gene from a bacterium into a grape to make it resistant to viruses. Or they can engineer maize that resists drought or potatoes that resist pests, so farmers can use less pesticides on their crops.
For thousands of years we have been tampering with the genes of plants by traditional breeding. But there's a key difference here - with traditional plant breeding genes cross within the same species. But GM allows plant breeders to break the species barrier. And for critics this is fundamentally unnatural.
The fear is that the proteins produced by these foreign genes might be dangerous. Either because the protein itself is poisonous or because it might alter the chemistry of the plant so that the plant becomes toxic. Detailed tests are performed on the plants to discover if they are substantially biologically and chemically the same as before modification and if they have become toxic or allergenic.
Critics believe that no amount of testing can ensure that GM crops are completely safe. They believe that there is too much we don't understand about the complex genetic make-up of living organisms. And that even though there is little evidence so far, there may be a risk that genetic modification could cause effects so unexpected that they will be missed by all the tests biotech scientists carry out.
In contrast genetic engineers claim their work is safer and more predictable because they are moving just one or two specific genes, and they can more easily test the effects.
But those who campaign against GM have another fear: that the genes from the engineered plant will spread throughout the plant world, creating new strains of superweed and superbug we cannot control.
Horizon explores the key elements of scientific facts to try to answer the ultimate question: do the dangers of GM foods outweigh their benefits?
Daha Fazla OkuPlanet Hunters
If extra-terrestrials do exist they must have a home. Horizon tells the story of the race to find out where in the Universe this might be. The answer, for scientists across the world, lies in the hunt for planets around distant stars.
Stars which are trillions of miles away from our own solar system.
But the history of the planet hunters is littered with failure. Centuries of searching had thrown up nothing. It was time for the new style planet hunters to step in. However, it is only in the last ten years that these scientists have had the technology to succeed. Even now looking for these distant planets is far from straightforward.
The planets themselves are so faint that they cannot be seen, even by the most powerful telescopes ever built. Instead the astronomers must devise ingenious ways to search for clues to their presence. They examine stars just like our own Sun, across the galaxy, for any give-away characteristics that might indicate that they too have planets circling around them.
A Swiss team finally struck gold in 1995 - convinced they'd detected a star that must have its own planet. Their discovery was the first of its kind but not the last. Other teams started to get lucky and suddenly it seemed like there were stars with planets everywhere. But the scientific community soon became restless. All they had done so far was detect the presence of alien planets - without seeing one, it was impossible to work out what the planet was like.
If these planets really did exist it was time the scientists caught a glimpse of one of them. Only then would they be able to learn about the planet - its surface and its atmosphere. And only then would they know whether it could sustain life as we know it.
Horizon follows the trials and tribulations of the planet hunters and shares in the triumph of the Scottish team who, just a few months ago, became the first to achieve the ultimate goal - to capture the image of an alien planet. It is orbiting another star, 55 light years away from Earth.
The question is - how similar is this planet to our own and could it be home to alien life? Horizon uncovers the answers.
Daha Fazla OkuMoon Children
A handful of children around the world cannot tolerate the sun. Any exposure leads rapidly to skin cancer. They must either play indoors during daylight or be protected from head to toe in UV-proof suits. These children suffer from a strange and rare genetically-inherited disease, xeroderma pigmentosum, or XP, which means that within seconds of the sun's rays touching their skin, they are in danger of developing skin cancer.
Sun Children with XP are missing the crucial gene that repairs damage to DNA and so exposure to any carcinogen - UV light, or even cigarette smoke - is lethal. Unless, they are thoroughly protected they will die from cancer at an early age. There is no cure.
But these tragic children may may lead the way to new and better cancer treatment. Through studying XP sufferers, scientists have reached a whole new understanding of the genetic basis of cancer. They can now predict why one in three people will succumb to cancer. Scientists have discovered how the body survives damage and repairs itself and as a result of this, developed a radical new approach to treating cancer.
Horizon explores the story of one family, where 5 out of 7 siblings suffer from XP, and how they provide the final proof that genes and DNA repair are linked to cancer. It follows an intricate 40-year scientific detective story from the discovery of DNA, through the chance findings of the cells of the XP families that led to the unexpected insight that DNA is capable of repairing itself and that the failure of this repair system underlies most cancers.
After years of research, this insight is finally beginning to revolutionise medicine. Now a new concept in cancer drug therapy is just beginning medical trials based on the knowledge gained from children suffering from XP.

Mega-tsunami: Wave of Destruction
Scattered across the world’s oceans are a handful of rare geological time-bombs. Once unleashed they create an extraordinary phenomenon, a gigantic tidal wave, far bigger than any normal tsunami, able to cross oceans and ravage countries on the other side of the world. Only recently have scientists realised the next episode is likely to begin at the Canary Islands, off North Africa, where a wall of water will one day be created which will race across the entire Atlantic ocean at the speed of a jet airliner to devastate the east coast of the United States. America will have been struck by a mega-tsunami.
Back in 1953 two geologists travelled to a remote bay in Alaska looking for oil. They gradually realised that in the past the bay had been struck by huge waves, and wondered what could have possibly caused them. Five years later, they got their answer. In 1958 there was a landslide, in which a towering cliff collapsed into the bay, creating a wave half a kilometre high, higher than any skyscraper on Earth. The true destructive potential of landslide-generated tsunami, which scientists named "Mega-tsunami", suddenly began to be appreciated. If a modest-sized landslide in Alaska could create a wave of this size, what havoc could a really huge landslide cause?
Scientists now realise that the greatest danger comes from large volcanic islands, which are particularly prone to these massive landslides. Geologists began to look for evidence of past landslides on the sea bed, and what they saw astonished them. The sea floor around Hawaii, for instance, was covered with the remains of millions of years’ worth of ancient landslides, colossal in size.
But huge landslides and the mega-tsunami that they cause are extremely rare - the last one happened 4,000 years ago on the island of Réunion. The growing concern is that the ideal conditions for just such a landslide - and consequent mega-tsunami - now exist on the island of La Palma in the Canaries. In 1949 the southern volcano on the island erupted. During the eruption an enormous crack appeared across one side of the volcano, as the western half slipped a few metres towards the Atlantic before stopping in its tracks. Although the volcano presents no danger while it is quiescent, scientists believe the western flank will give way completely during some future eruption on the summit of the volcano. In other words, any time in the next few thousand years a huge section of southern La Palma, weighing 500 thousand million tonnes, will fall into the Atlantic ocean.
What will happen when the volcano on La Palma collapses? Scientists predict that it will generate a wave that will be almost inconceivably destructive, far bigger than anything ever witnessed in modern times. It will surge across the entire Atlantic in a matter of hours, engulfing the whole US east coast, sweeping away everything in its path up to 20km inland. Boston would be hit first, followed by New York, then all the way down the coast to Miami and the Caribbean.
Daha Fazla OkuConjoined Twins
Conjoined twins are among the rarest of human beings. There are probably fewer than a dozen adult pairs living in the world today. Only a few hundred pairs of conjoined twins are born in the whole world each year - they appear about once in every 100,000 births - but more than half of them are stillborn, and one in three live for only a few days.
Of those who survive, a very small number will be selected for separation surgery. But as there are few hospitals with the skills and experience to perform this kind of surgery, separation is still a very unusual event. The harrowing decisions which surgeons have to make when faced with conjoined twins have been highlighted by the recent case in Manchester, England. Separating conjoined twins is not only technically challenging; it can involves life and death decisions about whether one twin should be sacrificed in the hope of saving the other. But "sacrifice surgery" has a poor record of success, and the Manchester case is the latest round in an international debate about the value of separation operations.
The confidence of the surgeons, who believe that separation is essential, is challenged by medical historian, Dr Alice Dreger of Michigan State University. She argues that twins themselves might take a different view - if they were ever given a chance to express it.
Horizon interviews two pairs of adult conjoined twins - Lori and Reba Schappell in Pennsylvania and Masha and Dasha Krivoshlyapova in Moscow. Lori and Reba are joined at the head; Masha and Dasha are joined in their lower body. They say that they prefer their conjoined lives, despite the problems and challenges, rather than face the risks of separation surgery.
Lori and Reba live independent lives in their own apartment in Pennsylvania; Lori enjoys working with computers and Reba is developing a career as a country singer. Masha and Dasha had a difficult childhood; they were subjected to medical experimentation when they were very young and hidden away from the public. Since the end of the communist era they have been able to tell their story. Their autobiography is being written by a British journalist, Juliet Butler.
Horizon also follows surgeons at the Red Cross Children's Hospital in Cape Town, Africa as they plan to separate eight month old twins, Stella and Esther Alphonce. The baby girls are joined at the hip, and the surgeons have little doubt that they can and should be separated, even though the operation carries risks of disability for the twins. Historically conjoined twins who were not, or could not be separated have lived successful lives, even if this involved putting themselves on public display. The original Siamese twins, Chang and Eng Bunker, were joined by a narrow strip of flesh and could easily be separated today.
Like Millie and Christine McCoy, who also lived in the USA in the middle of the last century, they earned fame and fortune touring the world. But life for conjoined twins has never been easy, Millie and Christine were kidnapped and sold several times in their childhood. The British conjoined twin sisters, Violet and Daisy Hilton, provoked a scandal in the USA when one of them tried to get married. They did eventually marry, but they were never separated. The tragedy for conjoined twins who spend their lives together is that they inevitably die together too. When one twin dies, the heart of the other twin keeps pumping until he or she is drained of blood.
Is this another reason why twins should be separated when they are young? There are no simple answers, because every pair of twins is unique.

It sometimes seems as if our planet has no secrets left - but deep beneath the great Antarctic ice sheet scientists have made an astonishing discovery. They’ve found one of the largest lakes in the world. It’s very existence defies belief. Scientists are desperate to get into the lake because its extreme environment may be home to unique flora and fauna, never seen before, and NASA are excited by what it could teach us about extraterrestrial life. But 4 kilometres of ice stand between the lake and the surface, and breaking this seal without contaminating the most pristine body of water on the planet is possibly one of the greatest challenges science faces in the 21st century.

There were 5 crew and 6 passengers on board the plane - named "Stardust". But Stardust never made it to Santiago. Instead it vanished when it was apparently just a few minutes from touchdown. One final strange Morse code radio message - "STENDEC" - was sent, but after that nothing more was heard from the plane. Despite a massive search of the Andes mountains no trace of the plane was ever found. For 53 years the families of those who disappeared have not known what happened to their loved ones. But earlier this year the plane suddenly reappeared on a glacier high up in the Andes, more than 50 km’s from the area where the plane was last reported.
Daha Fazla OkuThe Secret Treasures of Zeugma
In the summer of 2000, one of the great frontier cities of the Roman Empire, the city of Zeugma, all but disappeared from the face of the Earth under the flood waters of a dam. In a bid to modernise, the Turkish government has embarked on one of the most ambitious engineering projects in the world, building a series of dams on the Euphrates over the past twenty years. Almost every dam threatens ancient remains that lie below in one of the most archaeologically rich regions of the world. The completion of the Birecik dam, featured in this film, has flooded the valley where Zeugma is buried. The city on the flat plain has entirely disappeared and the waters have now risen to cover 30% of the city on the hillside.
Horizon tells the story of the archaeologists' fifth and final visit, struggling to save what they could before the dam waters rose. It witnesses the uncovering of some of the most beautiful examples of Roman art ever found. The team’s discoveries at Zeugma caused an international outcry and further excavations were hurriedly put together.
Since 1995, French archaeologists Pierre Leriche and Catherine Abadie-Reynal have taken up the challenge to save what they can from the city before the dam is finished. The archaeologists have two main tasks - to uncover the history of this desperately under-excavated region of Turkey and to remove what treasures they could from the site before they were lost forever. On this, their final excavation, they had to work against the clock: they only had a permit to dig for six weeks
Zeugma was founded by one of Alexander the Great’s generals, Seleucia Nicator, and prospered under later Roman rule. It became one of the major cities of the Roman eastern frontier with a garrison of over 6,000 soldiers. The city’s bridge across the Euphrates made it one of the most critical trading cities in the region, on the silk routes to the East. The archaeologists know that the city contains vital clues to the history of the region. Previously looted exquisite mosaics have hinted at the treasures of its past that must be buried somewhere in the vast site.
The part of the old city on the Euphrates flood plain, Apamea, was the first to go. But the archaeologists didn’t stand a chance of excavating it in such a short amount of time. So using a technology originally developed for finding oil and mineral deposits, they instead generated a picture of the buried city just as it lies below ground. They discovered a preserved ancient Greek city, laid out in a perfect grid. Meanwhile, in the remains of a Roman villa across the river, the archaeologists had an extraordinary stroke of luck.
With only five days left on the excavation permit, Catherine Abadie-Reynal unearthed a masterpiece: a beautiful Roman mosaic floor. The discovery caused an international outcry and hit the headlines across the world. The archaeologists were granted more days to excavate, but they could not stem the tide of the dam project.
With time running out, they uncovered more stunning mosaics in the villa. They were dug out from the site and sent to a local museum at Gaziantep - just in time. By mid June 2000, the newly uncovered fourteen room villa disappeared underwater. By October, the level of the water finally settled to form a vast, still lake in the valley. All excavations at the site ceased.
There's recently been a move by the Turkish government to declare Zeugma a site of special archaeological interest. The remainder of the ancient city on the hillside could, in theory, still be explored.
The dam will not only erase much of Zeugma from history. It will also displace 30,000 people, mostly Kurds, from the villages they have lived in for generations. For many, the loss of Zeugma is a tragedy.
Daha Fazla OkuValley of Life or Death
At the heart of the AIDS epidemic in Africa, there is a deadly mystery that has puzzled scientists for years. There are groups of people who are four times less likely to get HIV than other people, sometimes living just yards away, across a single valley - people with apparently similar behaviour and lifestyle. Scientists realised that if they could understand why these people are so much less vulnerable to the HIV virus, it might lead to an answer that could save millions of lives. And after 15 years of detective work it turns out there may be a remarkably simple answer: the high risk areas for HIV coincide with tribes who are uncircumcised. In Africa, it seems a man is much more likely to get HIV if he is uncircumcised.
In Kaoma, Western Zambia, a young boy is on his way to the sacred Mukondaa - the tribal circumcision ground. Around him the tribal elders are gathered, dressed in their ceremonial garb, and vivid masks. But the young boy himself is an outsider, not from this tribe, and none of his relatives or ancestors have ever been circumcised. In fact, his parents are only prepared to break the taboo of their own tribe because they believe that circumcision could save his life by protecting him from AIDS. At first sight this belief seems like the kind of superstition to which desperate people often turn in times of plague. But now there is scientific evidence that suggests these people could well be right.
There have now been twenty seven statistical studies that show a big difference in HIV infection between circumcised and uncircumcised men. For example, among the uncircumcised people of Kisumu in Western Kenya, a man is three times as likely to get AIDS than his circumcised neighbours. Among truck drivers in Mombasa the difference is four-fold.
Horizon travels across Africa, tracing the work of scientists who have unearthed the statistical data behind this correlation. At the same time microbiologists have been battling to understand the complex and insidious virus, and their work indicates that the foreskin may be a key entry point for HIV. The logical conclusion for these scientists is that if you remove the foreskin, you begin to protect the man. No-one believes that circumcision can protect completely - the evidence so far only indicates that it reduces the risk of infection by HIV, and then only during heterosexual sex. Unquestionably, condoms are still the best protection. But in the many countries where the use of condoms is minimal, it seems that circumcision might help to reduce the spread of AIDS.
In the absence of a vaccine for AIDS, and the lack of condom use in the developing world, should governments think the unthinkable and encourage the circumcision of young boys in non-circumcising tribes as a public policy? Opposing this idea are the voices of tribal elders who are loath to change tribal traditions that have existed for generations, and a fierce Western anti-circumcision lobby which believes that circumcision is a form of mutilation and violates basic human rights.
Daha Fazla OkuExtreme Dinosaurs
Amazing new discoveries in South America are revolutionising what we thought we knew about the dinosaur world. It now seems that South America was home to both the largest meat-eater - so new it's still without a name - and the largest herbivore - the enormous long-necked Argentinasaurus. And what's more, these dinosaurs lived at the same time in the same place. So it's possible that like in a science fiction movie, in this prehistoric world these two giants of their kind fought each other in a spectacular clash of the Titans.
Horizon follows the scientists to Argentina as they unearth one of these giants - a brand new species of dinosaur; the biggest carnivore ever discovered. Not yet named, this new creature is even bigger than T. rex, the so-called 'king' of the carnivores. The new giant South American predator had a skull bigger than a man that was full of serrated, knife-like teeth and long powerful jaw muscles. They could dissect their prey with almost surgical precision.
But even this formidable killing machine couldn't alone have taken on the massive long-neck, Argentinasaurus, which was the height of a five-storey building. It must have hunted in a pack. The problem is, the mega-meat-eaters have always been assumed to have been solitary creatures. The evidence shows that they lived and hunted alone. If they weren't pack hunters, then they would never have attacked Argentinasaurus. So it looked like the idea of a mighty battle between these two giants was simply science fiction. But extraordinary new clues are proving otherwise.
Palaeontologist Phil Currie had long suspected that the giant carnivores might indeed have hunted in packs and he set out to find the proof. Only now after many years' work have Currie and his team unearthed the clues that are beginning to convince other palaeontologists that the huge carnivorous dinosaurs hunted in groups. With the help of his colleague Rodolfo Coria, Currie has discovered not one but two fossil bone-beds showing packs of massive carnivorous dinosaurs that have lain buried for millions of years. Each pack - one found in the badlands of Alberta, Canada and the other in Patagonia, Argentina - contains a whole range of individuals, from young through to fully mature adults indicating that they lived alongside in a herd. He's convinced that these dinosaurs were buried together because they were living together.
These new finds are good evidence that these creatures really did hunt as a team. And that means a ferocious pack of enormous carnivorous dinosaurs roaming the lands of South America may indeed have taken on a huge Argentinasaurus in a fight to the death. So it may not just be science fiction - the Clash of the Titans could have happened after all.
Daha Fazla OkuSupermassive Black Holes
In June 2000, astronomers made an extraordinary discovery. One that promises to solve one of the biggest problems in cosmology - how and why galaxies are created. Incredibly, the answer involves the most weird, destructive and terrifying objects in the Universe - supermassive black holes. Scientists are beginning to believe that these forces of pure destruction actually help trigger the birth of galaxies and therefore are at the heart of the creation of stars, planets and all life. Supermassive black holes are so extraordinary that until recently, many people doubted that they existed at all. The idea of giant black holes the size of the Solar System seemed more like science fiction that reality - such monsters would be so powerful that they could destroy the very fabric of the Universe. But in the last five years a series of discoveries has changed our understanding of supermassive black holes and galaxies forever. Using the powerful Hubble Space Telescope, scientists have been scanning nearby galaxies, searching for these giant black holes. It's a difficult job - by their very nature black holes swallow light - so can never be seen. So what scientists have been looking for is the effect of their massive gravity, hurling stars around them at immense speed. What they've found is more extraordinary than anyone could ever have imagined; not just evidence that these vast destructive monsters exist… but so far they're in every single galaxy toward which they have turned their telescopes. These giant agents of destruction appear to be common throughout the Universe. Scientists now think supermassive black holes are a fundamental part of what a galaxy actually is. Lurking at the heart of every single galaxy is a giant black hole of apocalyptic proportions - and that includes our own galaxy, the Milky Way. Astronomer Andrea Ghez has been studying the heart of the Milky Way for the last five years. What she's discovered is irrefutable evidence for a giant black hole, 3 billion times the size of our own sun. A black hole that could destroy the entire Solar System. And as Horizon was filming in July 2000, Ghez got some terrifying images - of the giant monster sucking up gas and stars at the galaxy heart. So what is this giant monster doing at the heart of our galaxy? What effect will this giant black hole 25,000 light years away have on us and the rest of the galaxy around it? These are questions that have been puzzling astronomers for the last few years - and in June, two separate groups of scientists found evidence that points to a startling answer. Rather than being destructive parasites, it seems that supermassive black holes may be essential in the very creation of the galaxies they live in. Exactly how our galaxy was created has mystified astronomers and physicists for years. Although there have been many theories, there's little evidence to explain how the gas in the early Universe condensed to form the galaxy we see today. Now scientists realise they've been missing a vital ingredient - a supermassive black hole. The immense gravity of a giant black hole might trigger the gas to collapse in the first place. By churning up the gas around it, a giant black hole would trigger the birth of stars, planets and life itself. Despite being the most destructive thing in the Universe, scientists now think our supermassive black hole could be crucial in creating the galaxy as we know it. The supermassive black hole in our own galaxy may be the reason we exist, but recent work suggests it may also be our end. At present Earth is so far away from the black hole that it can't affect us, but physicist John Dubinski thinks all that could change. In January 2000 he graphically simulated the final fate of our galaxy. In 3 billion years we will collide with the next door galaxy, Andromeda. The resulting apocalypse will force the Earth and our Solar System out of orbit. Dubinski has calculated a worrying 50:50 chance that we'll be sent hurtling in towards the black hole at the centre of this maelstrom. This would be fatal for the Earth.
Daha Fazla OkuThe 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 believed that what he called our 'gender identity' - what makes us think, feel and behave as boys or girls - is not fully formed by the time of birth. While we may have some innate sense of being a boy or a girl, for up to two years after birth, our brains are, in effect, malleable and we can be taught to grow up as either a boy or girl by how we are raised - by the toys we are given, the guidance we receive from adults and the clothes we are given to wear. This became known as the 'theory of gender neutrality'.
Dr Money had reached this conclusion by working with a rare group of individuals born with ambiguous genitals - people known as intersexuals or hermaphrodites. Dr Money studied groups of intersex children, and concluded that these children could be brought up as either boys or girls regardless of their genetic or physical sex. The legacy of Dr Money's work was a revolution in the treatment of 'intersex'. From the 1950s to the present day many intersex children born with a tiny penis are reassigned as female even if they are actually genetically male.
But not everyone agreed with Dr Money's theories. Since the 1950s a small group of scientists including Dr Milton Diamond have questioned John Money's work. Diamond believed that our sex is already defined in our brains before we are born. He was convinced that the power of our genes and hormones was so strong that no amount of nurturing could override them.
But John Money's theory had already become firmly accepted around the world and the most dramatic confirmation of the theory came from one particular case - the case of Bruce Reimer.
Bruce was a normal boy, not an intersex child, and yet the decision was made to turn this boy who had lost his penis, into a girl. Under the guidance of Dr Money and his team at Johns Hopkins University this baby boy was surgically changed into a girl. After surgeons at Hopkins had castrated baby Bruce, he became baby Brenda. The family were instructed how to bring up Brenda as a normal little girl. According to Dr Money's theory she would grow up believing herself to be female and would go on to live a normal happy life as a woman. It seemed the ultimate test that nurture could override nature.
Thirty years after Bruce became Brenda, the impact of this extraordinary story continues. After almost 14 years living as a female, Brenda Reimer reverted to her true biological sex - the case of the boy who was turned into a girl had failed. Brenda took the name David and for the last twenty years he has lived anonymously in his hometown of Winnipeg. For almost all this time no one knew the outcome of John Money's celebrated case. But now that David has gone public, the case is being widely discussed once again and its impact on John Money's theory of gender development and the treatment of intersex children is being hotly debated.

Horizon puts Graham Hancock's controversial theories about the past to the test, dissecting his evidence for a lost civilisation.
Graham Hancock offers various pieces of evidence to support his theory. He claims that the mysterious lost civilisation left its mark in ancient monuments, which he calculates were built to mirror certain constellations of stars. His hugely popular ideas have attracted such a wide audience that they stand to replace the conventional view of the past, which is based on scientific evidence that the civilisations of the ancient world were developed independently, by different peoples, on different continents.

Daha Fazla OkuThe Mystery of the Persian Mummy
In November 2000, the international press reported an amazing find: a mummy, which was claimed to be that of an ancient Persian princess, over 2,600 years old. She was encased in a carved stone coffin, inside a wooden sarcophagus and was wearing an exquisite golden crown and mask.
Her cloth-bound body was dressed with golden artefacts, with an inscription on her breastplate that read, "I am the daughter of the great King Xerxes, I am Rhodugune." All the internal organs had been taken out of her body, in the same way that the ancient Egyptians mummified their dead. It was the find of a lifetime, one of the most magnificent ancient treasures ever to be unearthed in the area.
When the curator from the Karachi National Museum, Dr Asma Ibrahim, began her investigations into the mummy, a different story began to emerge. Horizon follows the story as forensic experts all over the globe analyse the mummy and her magnificent trappings and discover that she is an elaborate fake with a terrible secret.
The mummy was found in a house in the desert region of Pakistan during a police raid, after a tip-off that it was to be illegally sold on the antiquities black market for $20m, and smuggled out of Pakistan. The Persian princess was immediately hailed as a major archaeological discovery. In fact, no Persian mummy had ever been found before, let alone a royal mummy. Mummification to preserve bodies had always been thought to be unique to the ancient Egyptians.
However, there were some strange puzzles about this beautiful princess. The inscriptions on the mummy's breastplate had some grammatical errors. And there were peculiarities in the way she had been mummified. Several detailed operations common to Egyptian mummifications had been omitted. So it began to look like the mummy was not the princess she was supposed to be; perhaps she was a more ordinary ancient mummy dressed up to be a Persian princess by forgers trying to increase her value.
As scientists investigated more closely, it became clear that this mummy had an even darker history. Computerised tomography (CT) scans and X-ray photographs of the body inside the mummy revealed that this was no ancient corpse but a woman who had died in the recent past, and that her neck was broken. An autopsy confirmed that this woman may indeed have been murdered to provide a body for the fakers to mummify - a body they intended to pass off as an ancient mummy for millions of dollars on the international art black market. And, finally there is evidence to suggest that they have done this not once but three times, raising the spectre of a mummy factory and the terrifying thought of yet more victims.
Daha Fazla OkuThe Ape that Took Over the World
In 2001, scientists announced an amazing discovery: the oldest skull of a human ancestor ever found. The 3 million year old fossil was remarkably complete, and unlike any previous fossil find. Its discovery - by a team led by Meave Leakey of the famous Leakey fossil-hunting family - has revolutionised our understanding of how humans evolved.
The great mystery of our evolution is how an ape could have evolved into the extraordinary creature that is a human being. There has never been another animal like us on the planet. And yet ten million years ago there was no sign that humans would take over the world. Instead the Earth was dominated by the apes. More than 50 different species of ape roamed the world - ten million years ago Earth really was the planet of the apes. Three million years later, most had vanished. In their place came something clearly related to the apes, but also completely different: human beings!
For years scientists searched for the first key characteristic which had allowed us to make the huge leap from ape to amazing human. At first they thought the development of our big brains was decisive. They even found the fossil that seemed to prove it, until along came the famous three million year old fossilised skeleton Lucy. This quashed the big brain theory, because here was a human ancestor which clearly walked on two legs, just as we do, but had the tiny brain of an ape. It seemed that the development of walking on two legs (bipedalism) was the first key human characteristic, the thing that set us on the road to becoming human.
Lucy soon became even more important. She seemed to defy the laws of evolution. Normally a major evolutionary adaptation like walking on two legs is followed by what scientists call an adaptive radiation. Many related species quickly evolve from an initial evolutionary innovation. It gives a very bushy evolutionary family tree, with many different but related species. Scientists knew that the human branch of the family tree had begun about six or seven million years ago, when the planet of the apes ended. And yet there was no sign of an adaptive radiation. The family tree showed just a straight line leading from the planet of the apes through to Lucy.
All that has changed with Meave Leakey's spectacular new discovery, named Kenyanthropus platyops or, less formally, Flat-faced Man. Her find is the same age as Lucy's species, but also completely different. It's proof that there were two different bipedal human ancestors living at the same time, more than three million years ago. And it's the first sign of the adaptive radiation that the theory of evolution says should have followed the planet of the apes.
Daha Fazla OkuLife Blood
Matthew Farrow was born with a rare and fatal blood disease, Fanconi's anaemia. His family and doctors thought he was going to die. Instead, aged just five, he became the first person in the world to be given a radical new treatment that few believed would work. It saved his life.
The treatment was remarkably simple. A small quantity of blood taken from a newborn baby's umbilical cord and placenta was infused into him. Thanks to this cord blood, Matthew Farrow is now a healthy teenager and the treatment he helped to pioneer is giving hope to hundreds of critically ill children around the world.
Cord blood contains a large number of blood stem cells, the mysterious factory cells that make all the red and white blood cells our body needs. Stem cells can rebuild a sick child's blood system in just a few weeks, by producing healthy new blood cells.
Until Matthew's case, babies' umbilical cords and placentas were just thrown away at birth. Established medical thought said the only source of blood stem cells was the bone marrow and the only treatment for children with advanced blood cancers was a bone marrow transplant. One in three affected children cannot find a suitable bone marrow donor, and there was a desperate need for an alternative.
The first doctors to suggest cord blood as an answer were dismissed as dreamers.
But pioneering work over the last twenty years, mainly in America, has shown that the tiny quantity of blood contained in a newborn's umbilical cord and placenta is rich in the crucial stem cells. It is now being used to help to treat a broad range of blood cancers and serious genetic blood diseases.
However, even its advocates admit that cord blood is no miracle cure. Cord blood is a significant medical breakthrough, but it cannot save everyone who is treated with it.
This powerful and moving film follows patients and their doctors as they go through this arduous new treatment. Not all patients survive the transplant. However, for some patients this treatment is a lifeline when there is no option of a bone marrow transplant. Since 1990, over a thousand lives have been saved by this new treatment.

Daha Fazla OkuCloning the First Human
Doctors Panayiotis Zavos and Severino Antinori claim they are ready to embark on the greatest human experiment of our age. They say they will attempt to clone a human being before the year is out. Most people think the objections to this are ethical - human cloning would create many moral dilemmas.
There is another question that few ever ask: is the science actually ready yet for cloning healthy humans? Horizon follows the latest research, which has led many scientists to believe that Zavos and Antinori's plans to clone the first human could end in tragedy. The programme also meets couples like Matthew and Desiree Racquer who think cloning offers them the only way to raise a child who is truly their own.
For decades, cloning remained within the realms of science fiction. The idea that instead of combining a sperm and an egg, a new human could be made from a single cell taken from an adult, seemed completely absurd. But that all changed in February 1997, when the Roslin Institute introduced the world to Dolly the sheep - the first animal cloned from an adult. Ever since Dolly, scientists have been continuing to experiment with cloning animals. So far, they have succeeded in cloning sheep, cattle, pigs, goats and mice, fuelling the belief that humans could be next.
But even Dolly's creator, Professor Ian Wilmut, is concerned that beneath the veneer of success lies a disturbing reality. Most cloning attempts on animals so far have resulted in failed implantation or abnormal foetuses. Of the animals born alive, some soon die of catastrophic organ failure. Others appear to be healthy for weeks or even months, then die suddenly, sometimes from bizarre new illnesses which do not occur in nature.
Years of painstaking work are only now revealing some vital clues to what is going wrong. Horizon talks to the scientists who have uncovered new evidence, suggesting that the process of cloning itself causes subtle errors in the way genes function. These random errors may be like a time bomb inside every clone, causing some of the strange - often fatal - problems. There's no reason to think cloned human babies would fare any better. According to embryologist Dr Susan Avery, death might be the best outcome for many human clones. If they survived, they would suffer from catastrophic illnesses that modern medicine is powerless to prevent or cure.
Dr Zavos claims that these problems are the result of the still unsophisticated methods being used by animal researchers. Using advanced in vitro fertilisation ('test tube baby') techniques, he claims that he will strive to make human cloning safer than natural reproduction. Now though, it seems that some IVF procedures themselves are being investigated for possible harmful effects on the long term health of children. Professor Gerald Schatten of the University of Pittsburgh reveals evidence of these risks, which could be magnified in cloning.
Most reproductive specialists believe that the danger to any human born by cloning is enormous. But the would-be human cloners are determined to clone a human baby. If they proceed, they may be courting tragedy.
Daha Fazla OkuThe Mystery Of Easter Island
On Easter Day 1722, Dutch explorers landed on Easter Island. A civilisation isolated by 4,000km of Pacific Ocean was about to meet the outside world for the first time in centuries. The strangers were about to find something very strange themselves - an island dotted with hundreds of huge stone statues and a society that was not as primitive as they expected. The first meeting was an immense clash of cultures. (Bloody too: the sailors killed ten natives within minutes of landing.) Where had the Islanders originally come from? Why and how had they built the figures? Modern science is piecing together the story, but it is far too late for the Easter Islanders themselves.
They were virtually wiped out by a series of disasters - natural and man made - that brought a population of 12,000 down to just 111 in a few centuries. The Island's inhabitants today all have Chilean roots, making solving the mysteries even harder. There is no one to ask about the first people of Easter Island. Although fragmentary legends have been passed down, only science can hope to explain the rise and fall of this unusual civilisation.
Daha Fazla OkuLiving Nightmare
Sleeping is an essential part of everyone's life yet it remains little understood is barely understood. You might think it's a relaxing recharge but in fact your brain is working harder at times overnight than when you're conscious in the day.
Fresh insight into why and how we sleep has come from studying people with sleep disorders, especially sufferers of narcolepsy. The condition means that people fall asleep many times a day, completely out of the blue. A less known symptom is paralysing attacks, that can cause narcoleptics to fall to the ground - unable to move - several times a day. If a way can be found to ease their symptoms, it could open the way to helping any of us to control our sleep patterns and perhaps even to go without rest while staying alert.
Gaynor Carr has been nodding off routinely since the age of seven. Her narcolepsy has made holding down a job impossible and made her question the idea of ever having children. Gary Beattie used to work in construction, until he fell asleep 7m up a ladder. He not only loses consciousness, his body becomes paralysed in a so-called cataleptic attack. Both of them say that showing emotion sparks the paralysing attacks and that has forced them to avoid laughing and crying. Bill Baird worked in finance but describes his stockbroking days as a race. The emotion of closing a deal would bring on a fit; he had constantly to hope he could get a client's signature before his almost inevitable collapse.

Daha Fazla OkuAverting Armageddon
The Earth is under constant bombardment. Each year, many fragments of debris hit our planet. Fortunately for us, most are so small that they burn up harmlessly in the atmosphere.
However, there are hundreds of larger asteroids orbiting near the Earth. Many scientists now believe that one of these hit the Earth 65 million years ago, killing the dinosaurs, along with 90% of all life on the planet. What is more, it is only a matter of time before the Earth is hit again.
Experts warn that nuclear weapons might not destroy an approaching asteroid. But Jay Meloch thinks he can use the power of the Sun to nudge an asteroid away from the Earth.
Until recently, no one took the asteroid threat very seriously. Yet the evidence that we are in danger is on our own doorstep. We need only look at the cratered surface of the Moon to realise that it has been pounded by impacts throughout its history.
Daha Fazla OkuDirty Bomb
A dirty bomb is a radiological weapon but unlike a nuclear bomb, its purpose is to contaminate rather than destroy. It uses normal explosives to disperse radioactive materials in the local environment, creating a hazard to health that could last for years unless cleaned up.
The relative ease of making such a bomb means it is a potent terrorist weapon but Horizon's investigation shows that the risk to health from most such devices need not be great. It also underlines the need for governments to act to secure radioactive sources from falling into criminal hands. Horizon deliberately avoids outlining the production process in any detail.
Horizon publishes the results of specially commissioned research, modelling two possible dirty bomb scenarios: attacks on either London or Washington DC. The main conclusion is that the health risks from a dirty bomb explosion are localised to people who are close to the incident or are in contact with the contamination. Although the modelled attack scenarios could have wide-ranging economic repercussions, the majority of the population of either capital city would have only a negligible increase in their risk of developing cancer.
Daha Fazla OkuSexual Chemistry (Update)
The drug Viagra revolutionised the treatment of sexual dysfunction in men on its launch five years ago. An accidental discovery, the tablet that gave impotent men the chance once more to have natural erections became the fastest selling pill in history and has earned its manufacturer, Pfizer, over $6bn.
The search is now on for a similar drug that could help women. Research is revealing that female sexuality is more complex than expected. For women suffering from a loss of desire many scientists believe that drugs acting on the brain may be the way forward. A pioneering Scottish study may have identified just such a drug and begun testing it scientifically.
An erection is achieved by filling the erectile tissue of the penis with blood. Blood vessels widen to allow blood in and then constrict to maintain the pressure. Male impotence was long thought to be a psychiatric effect, a result of stress, anxiety or depression. Medical advice was that there was not much to be done. Some patients refused to take this message on board.
Daha Fazla OkuThe 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 fossil evidence that Homo sapiens replaced other hominids around them and moved out of Africa into Asia and the Middle East, reaching Europe 40,000 years ago.
Prof Richard Klein believes art is a landmark in human evolution. Unquestionable art that's widespread and common suggests you're dealing with people just like us.

It was the simplest idea but one with enormous potential. If a gene is defective in the human body, just replace it with one that works properly. Gene therapy would mean that genetic disorders would become a thing of the past. Cancer would be cured, as would cystic fibrosis and hundreds of other genetic illnesses. Scientists were justifiably excited about the idea but, this enthusiasm that would end up costing one young man his life.
Jesse Gelsinger was born with a liver disorder, a rare condition called ornithine transcarbamylase (OTC) deficiency that stops the liver metabolising ammonia. People with the disease can suffer from brain damage or coma. At its most extreme the illness is fatal.
Jesse was lucky, able to lead a fairly normal life although he had a daily cocktail of drugs to control his condition. Jesse wanted to help others. When he was offered a chance to take part in a medical trial to test the safety of using gene therapy for OTC deficiency, he was keen to participate. He knew this was not a cure for his condition but that, by volunteering he might be able to help others in the future.
Although the concept of gene therapy is simple, the practice of administering the treatment is much more difficult. In order to replace defective genes, doctors must get working ones into the body and to the place where they are needed.
Daha Fazla OkuEarthquake Storms
Earthquakes are among the most devastating natural disasters on the planet. In the last hundred years they have claimed the lives of over one million people. Earthquakes are destructive mainly because of their unpredictable nature. It is impossible to say accurately when a quake will strike but a new theory could help save lives by preparing cities long in advance for an earthquake.
The surface of the Earth is made up of large 'tectonic' plates. These plates are in slow but constant motion. When two plates push against each other friction generates a great deal of energy. For this reason earthquakes occur most frequently on tectonic fault lines, where two plates meet. However these fault lines run for thousands of kilometres; predicting exactly where a quake will occur is nearly impossible.
In 1992, Dr Ross Stein was monitoring a large earthquake in a town in California called Landers. Three hours later, there was another quake 67km away at Great Bear. Stein believed that this was not simply an aftershock, instead he theorised the event at Landers had set off the earthquake at Big Bear. Stein believes that when an earthquake occurs the stress that has built up along the fault, is in part, transferred along the fault line. It is this energy transfer that causes other quakes to occur hours, days or months after the original.

Rudi Affolter and Gwen Tighe have both experienced strong religious visions. He is an atheist; she a Christian. He thought he had died; she thought she had given birth to Jesus. Both have temporal lobe epilepsy.
Like other forms of epilepsy, the condition causes fitting but it is also associated with religious hallucinations. Research into why people like Rudi and Gwen saw what they did has opened up a whole field of brain science: neurotheology.
The connection between the temporal lobes of the brain and religious feeling has led one Canadian scientist to try stimulating them. (They are near your ears.) 80% of Dr Michael Persinger's experimental subjects report that an artificial magnetic field focused on those brain areas gives them a feeling of 'not being alone'. Some of them describe it as a religious sensation.
His work raises the prospect that we are programmed to believe in god, that faith is a mental ability humans have developed or been given. And temporal lobe epilepsy (TLE) could help unlock the mystery.

265 people died when an Airbus operated by American Airlines crashed into the New York suburb of Queens in November 2001. The twin-engined jet took off from John F Kennedy Airport in fine conditions but hit trouble after just 67 seconds. In the following 38 seconds the plane started to disintegrate before nose-diving into the residential Rockaway area of the city.
Everyone aboard was killed (along with five people on the ground) so the crash investigators had to rely on eyewitnesses, recovered parts of the plane and information from both air traffic control and the flight data recorders. The discovery of the Airbus' vertical tailfin hundreds of metres from the fuselage immediately focussed attention on whether the pilots lost the ability to control the plane.
Why the tailfin detached was at the heart of the investigation by the National Transportation Safety Board. The airline and the manufacturer blame each other for creating a situation in which the stress on the rudder and tailfin exceeded the so-called ultimate load, the worst-case scenario set by the Federal Aviation Administration (FAA). A number of American Airlines pilots have taken matters into their own hands though: requesting transfers to other aircraft because of their safety concerns.
Daha Fazla OkuSARS: The True Story
Severe Acute Respiratory Syndrome didn't even have its name in February 2003, when it struck its first known victim, Johnny Cheng, in Hanoi, Vietnam. Within days, an international effort led by the World Health Organization (WHO) had massed scientific expertise to fight the mystery illness and avert the nightmare scenario of an uncontrollable pandemic sweeping the globe.
Amid attempts to quarantine high risk groups of people, it seemed only fear could spread more rapidly than the disease itself. Nothing was known about the condition - where it had come from, how it was passed on, how to spot it, contain it or treat it. The infection was described merely as 'flu-like'. But if this was a type of influenza, it was one that killed up to 15% of its sufferers.
The doctor treating Mr Cheng, who first contacted the WHO about the unusual symptoms, was one of six medics to die of SARS at the hospital. But the alarm had been raised and the Organization began to pull together a response. Colossal effort by scientists around the world - and unprecedented co-operation - followed. Meanwhile, the media made much of the risk posed by and to international travel, and watched financial markets respond in gloomy fashion.

Remember that long, hot summer? You might never see its like again. And all that talk of global warming? Forget it.
This season's first Horizon reveals that a growing number of experts fear Britain could be heading for a climate like Alaska. Our ports could be frozen over. Ice storms could ravage the country, and London could see snow lying for weeks on end. It would be the biggest change in the British way of life since the last Ice Age.
The first signs that such a disaster could happen came from deep within the ice sheet of Greenland. Scientists discovered that the Earth's past was littered with sudden, drastic drops in temperature.
The big question was: could it ever happen again? Clues came from tiny shells at the bottom of the Atlantic; a huge glacier on the move in Arctic and some alarming discoveries in the far north of Russia.
In the end there came the terrifying revelation: the Gulf Stream, that vast current of water that keeps us warm, could be cut off.
According to one scientist, there is a one in two chance it will happen in the next century.
Others say a climatic catastrophe could be heading our way in just twenty years time.

What he can see is truly horrific; according to Drosnin, the world could end in an atomic holocaust - in 2006.
It sounds preposterous yet Drosnin claims to have serious scientific backing. Behind his findings lies the work of one of the world's most brilliant theoretical mathematicians, an Israeli professor called Eliyahu Rips.
In 1994, using exactly the same ancient code, Michael Drosnin accurately predicted the assassination of the Israeli Prime Minister Yitzak Rabin - twelve months before it occurred.
Drosnin's books on the Bible Code have been translated into most of the world's major languages and are read by millions of people. If he's right, he's stumbled on one of the most important discoveries ever made.

Mixing powerful and deeply moving footage with telling forensic analysis, Horizon reveals what really went wrong on the Space Shuttle Columbia. The film's final revelation is telling. If NASA had acted differently, all seven astronauts could have been brought back to Earth alive.
The film begins with the astronauts' final moments and shows the haunting scenes at Mission Control at the moment the disaster struck.
What then follows is a disturbing detective story as the investigators gradually realise that the tragedy was caused by the failure of a small panel on the shuttle's left wing that had been built to be indestructible.
No one had ever thought such an accident was possible. It has led to the shuttle being grounded for the foreseeable future.
But that wasn't all. The film also shows that NASA had a number of options to bring the crew back safely - if only it had commandeered a spy telescope to visually inspect the damage. It could even have launched a rescue mission.
But instead, NASA chose to rely on a computer programme for damage assessment. The programme got it wrong; as a result, there was no hope for those seven crew members.

Horizon tells the microbiological detective story in which some of the best brains in science have been pitted against the most extraordinary bug the world has ever seen.
In 1984 it was discovered that HIV was the cause of AIDS. Straight away, there were confident predictions that there would be a vaccine ready for testing in just two years.
Back then, just 1,292 deaths from AIDS had been reported. Now the figure is 25 million dead. By 2010 it is predicted there will be 85 million infections and 70 million deaths. And after 20 years there is still no sign of a vaccine.
Despite work of dazzling complexity, the ambition of so many brilliant scientists has been constantly thwarted. Just as a vaccine seems to be working, the AIDS virus alters itself, and ten to fifteen years of work, and millions of pounds, go down the drain. These bitter disappointments are only compounded by the desperate human urgency of the work.
This is a story where the clock doesn't stop ticking.

To mark the hundredth anniversary of the Wright brothers inaugural flight, Horizon tells the remarkable story of Percy Pilcher.
He could have been the most famous aviator of them all. Four years before the Wright brothers, he had constructed his own aeroplane. But on the day it was due to take off for the very first time, something so terrible happened that he was denied the chance of ever flying it. So Horizon has rebuilt his long lost flying machine to see if Percy Pilcher, the British amateur, could have claimed the glory and been the first person ever to fly.
This film mixes dramatic reconstruction with fabulous contemporary scenes and gripping science. With a specially assembled team of historians, aviation experts and our own test pilot, Horizon painstakingly rebuilds Pilcher's flying machine and puts it to the test. The results will leave you cheering.

Horizon's Time Trip is a thrilling journey deep into the strangeness of cutting-edge physics - a place where beautiful, baffling ideas are sometimes indistinguishable from the utterly crazy.
On this journey, we meet a time-travelling pizza, a brilliant mathematician in a ski mask and even God. The journey ends with a strange and dark conclusion - one which calls into question our very existence.
Ever since Einstein showed it was theoretically possible, the quest to travel through time has drawn eccentric amateurs and brilliant scientists in almost equal numbers. The amateurs include Aage Nost, who demonstrates his time machine in front of the cameras. The professionals include the likes of Professor Frank Tipler of Tulane University. His time machine sounds good - but it would weigh half the mass of the galaxy.
There is, however, one way that time travel to the past could be possible. And it would be much more convenient. Future civilisations could use computers to create exact replicas of the past. Unfortunately that idea has physics trembling in its socks. Because if you can generate a perfect virtual reality version of the past, who's to say we are not one of the replicas?

In a film that is in turns charming, disturbing and poignant, Horizon explores the relationship between science and the chimpanzee.
It began with a magical story. A young girl ventured alone into the jungle and befriended a group of chimpanzees. What she saw became the stuff of scientific legend. But then, last year came a terrible tragedy. Frodo, one of the chimpanzees she had helped make famous, killed a human baby. That shocking act brought into focus a huge debate about the relationship between humans and chimps, and what these primates have taught us about the origins of our own behaviour.
The saga of how Jane Goodall went into the jungle to study the chimps of Gombe in Tanzania has inspired novels and movies. Her observations revealed that chimpanzees were in many ways like humans. They used tools, had culture and even language. And what's more they had empathy. They were also capable of savage brutality against their own kind. Just like us.
In fact many began to think that the origins of aggressive human male behaviour could be traced back to our shared evolutionary ancestry with chimps. In other words, men are genetically programmed to be violent. But then came some disturbing questions.

With the help of doctors and scientists in America, Germany and Britain, Horizon unpicks the mystery of the Moscow theatre siege.
In October 2002, Chechen terrorists took a thousand people hostage in a Moscow theatre and threatened to kill them. The problem was how to get them out alive. A bloodbath seemed inevitable.
Three days later Russian special forces stormed the theatre using a secret gas to knock everybody out. 129 hostages died - apparently killed by the very gas that was meant to save them. Horizon investigates the mystery substance, and why so many died.
The Russian authorities insisted their secret weapon was not lethal. The claim provoked contempt from the victims families, and incredulity among doctors and scientists around the world. But were the Russians actually right?
The Russians offered just one clue. And in Germany there was a scientist who had the means to test it: a urine sample taken from one of the survivors shortly after he was freed. Horizon follows as extremely sensitive tests are performed to find out if the Russians were telling the truth, and uncovers a deeper secret.

This is the truth about the world's most famous, most glamorous and most controversial diet. The Atkins diet says that eating fat can make you thin. It says you don't need to bother watching the calories. Rene Zellweger, Geri Halliwell and a host of other celebrities swear by it. But many scientists think it is scientific nonsense. Some even believe it is dangerous. Horizon cuts through the confusion and provide the answers.
When Dr Atkins first launched his diet, he was accused of breaking one of the most fundamental laws of nature. Scientists said that if you eat more, you'll get fatter. They also said it could kill. Fat increases your cholesterol levels. You'd get a heart attack.
The only problem was that people who followed the Atkins diet got thinner. Much of the rest of us got fatter. Then came studies showing that cholesterol levels can actually improve on the Atkins diet.
So what was going on? Horizon's investigation seems to show that the diet may really work - but for a reason and in a way that no scientists or even Atkins himself had seriously considered.
Daha Fazla OkuSecrets of the Star Disc
This is the extraordinary story of how a small metal disc is rewriting the epic saga of how civilisation first came to Europe, 3600 years ago.
When grave robbers ransacked a Bronze Age tomb in Germany, they had no idea that they had unearthed the find of a lifetime. But they knew that it was worth selling. It was a small bronze disc of exquisite design. So they contacted the archaeologist Harald Meller, offering to sell it to him for €300,000.
Meller went deep into the criminal underworld and, after a police sting, he got his disc. It depicted the sun, the moon and the stars. This suggested an understanding of the heavens greater than that of the first great civilisations, like Egypt. Could it possibly be real?
After exhaustive tests, the disc was declared genuine. Then a team of crack scientists pieced together what it meant. What emerged is a true marvel.
This disc, it seems, is a Bronze Age Bible, combining an advanced understanding of the stars with some of the most sophisticated religious imagery of the age. In intellectual achievement and also age, it surpasses anything yet found in Egypt or Greece. It seems that civilisation had already dawned in Europe.
Daha Fazla OkuThe 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 achievement of almost incalculable brilliance. Some speculated this technology could spell the end of the entire silicon chip industry.
Crucially, Schön's transistor was organic. Suddenly, this seemed to be the first step towards true nanotechnology, where minute computers could grow as living cells.
Scientists speculated about how these tiny machines could be used to target diseases with astonishing precision. Others wondered - could the military use them as a new weapon? Others, including Prince Charles, were terrified. If these machines can grow by themselves, how do we stop them from growing?
What happened next would destroy reputations and shatter lives - because there was more to Hendrik Schön's discovery than anyone knew.

Thalidomide was one of the biggest medical tragedies of modern times. The images of children born with shrunken limbs still haunt anyone who sees them. And the tragedy is not over. Those children are adults today, still coping with their disability.
For many, thalidomide is a drug that should be consigned to the dustbin of history - an awful cautionary tale of the errors that science can make. But now it is making a comeback - as a radical treatment for incurable blood cancers. But can it possibly be safe to use such a dangerous drug again?
In a powerful and deeply moving film, Horizon tells the tale of thalidomide and how this drug that has become so infamous may now be giving hope to people who otherwise face death.
It also explores the mystery at the heart of thalidomide. It seems that the reason why it works for cancer may at least partly explain something that has long baffled scientists - why thalidomide caused such terrible damage to babies in the womb all those years ago.

Top quality diamonds at knock down prices? The only catch is: these rocks don't come out of the ground, but are made in a lab. This is the promise offered by a series of recent scientific breakthroughs.
For most of us, it seems we may soon be able to bejewel ourselves like movie stars. But for De Beers, the world's largest diamond trader, could this, one day, be a serious threat?
Following a dodgy meeting in Moscow, retired US Army General Carter Clarke acquired some experimental diamond growing machines, originally destined for the Russian military. He created the world's first gem diamond production line, to mass produce highly prized coloured diamonds.
In a secret location south of Boston, a father and son team developed a different technique. Robert Linares and son Bryant have made colourless diamonds, allegedly higher quality than those found in nature.
De Beers, at vast cost, set up a new scientific division called the Gem Defensive Programme. Its goal: to find ways to tell apart their natural diamonds from these new synthetic gems.
But will the new synthetics slip through De Beers detection net? And could anyone really tell the difference? Horizon tells the story of the Diamond Labs.

Tyrannosaurus rex - it's the scariest, meanest, most bewitching dinosaur of them all. Children are captivated by the sheer savagery of the teeth. Experts marvelled at the force of its bite - ten times more powerful than anything we know today. Movie makers made millions out of the terror it inspired. But could our picture of this monster be completely wrong?
Was T. rex in fact a slow lumbering creature, with hideously bad breath, that couldn't get anywhere close to catching a Triceratops. Was it really a scavenger that lived off the scraps left by others? Was T. rex, in fact, a wimp?
Featuring fabulous graphics and interviews with T. rex experts from around the world, Horizon looks at the new science that is challenging the legend of the dinosaur we love to hate.
Daha Fazla OkuProject Poltergeist
This is the story of two genuine scientific heroes. For forty years, John Bahcall and Ray Davis were engaged in a single extraordinary experiment - to find out why the Sun shines. In the end they would triumph. Davis would win the Nobel Prize and, thanks to their work, a whole new theory about how the universe is put together may have to be created.
At the heart of this story is a tiny, utterly mysterious thing called a neutrino. Trillions of them pass through your body every second, touching nothing, leaving no trace. Yet neutrinos are one of a handful of fundamental particles in the universe, essential to every atom in existence and clues to what makes the Sun work. But their ghost-like quality made trapping and understanding them immensely difficult.
What then followed was a bizarre series of experiments. They led from a vat containing 600 tons of cleaning fluid, to a vast cavern in a Japanese mountain, to a hole in the ground in Canada two kilometres deep.
What they would reveal would stun the world of science. It seems that neutrinos may be our parents. They may be the reason why everything, including us, exists.
Daha Fazla OkuThe Truth of Troy
It's one of the greatest stories ever told. The legend of Helen of Troy has enchanted audiences for the last three thousand years. In May this year a Hollywood film staring Brad Pitt and Orlando Bloom will be launched in Britain. But is there any reality to the myth? Horizon has unprecedented access to the scientist with the answers.
Since 1988 Professor Manfred Korfmann has been excavating the site of Troy. He has never before spoken at this length. He has made amazing discoveries - how large the city was, how well it was defended and, crucially, that there was once a great battle there at precisely the time that experts believe the Trojan war occurred.
But who had attacked the city and why?
Horizon then follows a trail of clues - the ancient tablets written by a lost civilisation, the sunken ship rich in treasure, and the magnificent golden masks and bronze swords of a warrior people. The film reaches its climax in a tunnel deep beneath Troy, where Korfmann has made a discovery that may reveal, once and for all, the truth behind the myth.
The story that emerges is one of great passion - but not, it seems, about love.

Daha Fazla OkuThe Truth About Vitamins
Every year we spend £300 million on vitamin supplements, but do they actually do us any good? Some believe they offer the promise of preventing or even curing some of the world's biggest killers, such as heart disease and cancer. Others claim that taking large doses of some vitamins may in certain cases be harmful. So what are the facts?
Nearly 40 years ago, one of the greatest scientists of the 20th century and double Nobel Prize winner, Linus Pauling, revolutionised the way people thought about vitamins. He claimed that by taking huge doses of vitamin C you could prevent or even cure the common cold.
He predicted that if everybody followed his advice, the common cold could even be eradicated. Many scientists dismissed his theory as quackery, but the public loved it and it helped launch a huge industry. But the latest evidence shows the great man was mistaken. Vitamin C can help you once have got a cold, but for most people it does nothing to prevent you from catching one in the first place.
Even if large doses of vitamin C do not prevent the common cold, some claim that it can still offer a more profound benefit. It is one of a group of vitamins called anti-oxidants that some believe can prevent illnesses such as cancer, Alzheimer's and heart disease.
In 2004, scientists in the United States claimed that people could be missing any of the potential benefits of taking one of the world's most popular anti-oxidant vitamin supplements, vitamin E, because their bodies might not be absorbing it. But our own investigation suggested that the American scientists' conclusion could be mistaken.
While most safety experts believe that vitamins C and E can be taken safely even in quite large doses, there is worrying evidence that one form of another common vitamin, vitamin A, could be linked to osteoporosis, a debilitating bone disease.
If the theory is right it means that a person's diet, or some supplements that they take every day to improve their health, could actually be slowly and silently weakening their bones.

Derek Tastes of Earwax
Is Wednesday red? Take part in our experiment to test whether your senses overlap.
Do melodies have a colour? Take part in our experiment to test whether you hear colours.
Imagine if every time you saw someone called Derek you got a strong taste of earwax in your mouth. It happens to James Wannerton, who runs a pub. Derek is one of his regulars. Another regular's name gives him the taste of wet nappies. For some puzzling reason, James's sense of sound and taste are intermingled.
Dorothy Latham sees words as colours. Whenever she reads a black and white text, she sees each letter tinged in the shade of her own multi-coloured alphabet - even though she knows the reality of the text is black and white. Spoken words have an even stranger effect. She sees them, spelled out letter by letter, on a colourful ticker tape in front of her head.
Both James and Dorothy have a mysterious condition called synaesthesia, in which their senses have become linked. For years scientists dismissed it, putting it in the same category as séances and spoon-bending. But now, synaesthesia is sparking a revolution in our understanding of the human mind.
Two synaesthetes seldom agree on the colours or tastes they experience. While Covent Garden may taste of crinkly chocolate to James, it's very unlikely to have the same taste for another synaesthete. And Dorothy's brother Peter, also a synaesthete, won't see M or Z in the same colour as she does. But despite these differences, scientists are now beginning to discover more and more overarching synaesthetic patterns.
Dorothy doesn't only see letters and numbers in colour. Music produces a riot of colour, too. As Dorothy hears notes going from low to high, her colours change from black and purple to mid-browns and then yellows and whites. Overall, lower notes evoke darker colours and higher notes brighter colours - and this pattern is true for most synaesthetes.
But surprisingly, when non-synaesthetes are asked to match colours and music, they show a similar pattern. Most of us seem to associate low notes with darker colours and high notes with brighter colours.
The evidence of the synaesthete in all of us doesn't end here. Another clue comes from the way we manipulate numbers. More than half of all synaesthetes who see coloured numbers also experience their numbers arranged in space around them. Heather Birt is such a synaesthete, and she's followed by a stream of numbers wherever she goes.
Recently, scientists started to investigate how non-synaesthetes deal with numbers. They found they're better at manipulating small numbers with their left hand, and their bigger numbers with our right hand. This suggests that we all somehow think of numbers as arranged in space, even if we're not aware of it. More evidence, it seems, that we're all synaesthetic to some degree. It's just that some people experience a more exaggerated version.
A few scientists believe that synaesthesia might even explain how we evolved two of the traits that define our species and have transformed our world - creativity and language.
Many famous artists have been synaesthetes - the jazz legend Miles Davis, for instance, and the painter Kandinsky. In fact, a number of studies suggest that synaesthesia may be more common among artists, poets and musicians. This has led some scientists to argue that synaesthesia and creativity may share a similar basis - that both may be down to brain processes that involve linking two seemingly unrelated areas.
Some believe that our common synaesthetic abilities may also have been the springboard to language. Connections between our senses of hearing and vision, for example, could have been an important initial step towards the creation of words. Our earliest ancestors may have first started to talk by using sounds that actually evoked the object they wished to describe. According to this theory, language could have emerged from the multitude of synaesthetic connections within our brains.
Daha Fazla OkuWhat Really Killed the Dinosaurs?
Until recently most scientists thought they knew what killed off the dinosaurs. A 10km-wide meteorite had smashed into the Yucatan peninsula in Mexico, causing worldwide forest fires, tsunamis several kilometres high, and an 'impact winter' - in which dust blocked out the sun for months or years. It was thought that the dinosaurs were blasted, roasted and frozen to death, in that order.
But now a small but vociferous group of scientists believes there is increasing evidence that this 'impact' theory could be wrong. That suggestion has generated one of the bitterest scientific rows of recent times.
Daha Fazla OkuMaking Millions the Easy Way
In the mid-1990s, a team of American science students took on the might of the Las Vegas casinos, and came home with millions of dollars. Hard working engineering students during the week, they became high-rolling gamblers by the weekend and proved that, in one game at least, the house doesn't always win.
The game was blackjack, and the students were from the world-renowned Massachusetts Institute of Technology (MIT). Their audacious winnings marked the climax of an arms race between casino and player that began 40 years earlier with maths professor Edward Thorp. He realised that the one feature of blackjack that made it different from other casino games also made it possible to beat.
In most gambling games - roulette, dice, slot machines, the lottery - events in the past do not determine the future. The odds are the same on every roll of the dice or spin of the wheel. Winning streaks or losing streaks may occur, but they are only one possible result from the set of all possible outcomes. A fair coin that has shown heads ten times, still only has a 50% chance of showing heads on the next flip.
Casinos and bookmakers make certain that the odds are always stacked slightly in their favour. In other words, over time, the house will always win.

But Newton thought gravity was powered by God, and even Einstein failed to completely solve it. Heading out with his film crew on a road trip across the USA, Brian fires lasers at the moon in Texas, goes mad in the desert in Arizona, encounters the bending of space and time at a maximum security military base, tries to detect ripples in our reality in the swamps of Louisiana and searches for hidden dimensions just outside Chicago.
Daha Fazla OkuIs Alcohol Worse than Ecstasy?
A trip through the highs and lows of the UK’s 20 most dangerous drugs.
Recent research has analysed the link between the harmful effects of drugs relative to their current classification by law with some startling conclusions. Perhaps most startling of all is that alcohol, solvents and tobacco (all unclassified drugs) are rated more dangerous than ecstasy, 4-MTA and LSD (all class A drugs). If the current ABC system is retained, alcohol would be rated a class A drug and tobacco class B.
The scientists involved, including members of the government's top advisory committee on drug classification, have produced a rigorous assessment of the social and individual harm caused by 20 of the UK's most dangerous drugs and believe this should form the basis of future ranking. They think the current ABC system is arbitrary and not based on any scientific evidence.
The drug policies have remained unchanged over the last 40 years so should they be reformed in the light of new research?

Professor Jim Al Khalili delves into over 50 years of the BBC science archive to tell the story behind the emergence of one of the greatest theories of modern science, the Big Bang.
The remarkable idea that our universe simply began from nothing has not always been accepted with the conviction it is today and, from fiercely disputed leftfield beginnings, took the best part of the 20th century to emerge as the triumphant explanation of how the universe began. Using curious horn-shaped antennas, U-2 spy planes, satellites and particle accelerators, scientists have slowly pieced together the cosmological jigsaw, and this documentary charts the overwhelming evidence for a universe created by a Big Bang.

In the wake of the swine flu outbreak, virologist Dr Mike Leahy goesw back over 50 years of BBC archives to explore the history of pandemics: waves of infectious diseases caused by bacteria, viruses or parasites.
Inspired primarily by the Horizon back catalogue, he works his way through the diseases that have been tackled head-on through the 20th Century: polio, malaria, smallpox, AIDS, and up to the present day with SARS and the H5N1 bird-flu virus.
Each pandemic episode tells us something about the world and our place within it. In his trip through the ages and the archives, Dr Leahy charts science's ongoing battle with nature and questions which one is winning. He makes a reasonable fist of the exercise, but is somewhat up against it as his source material can be patchy - first triumphant about man's successes and then defeatist when the previous triumph didn't work out quite as planned, etc.

Alcohol is by far the most widely used drug - and a dangerous one at that. So why are so many of us drinking over the recommended limits? Why does alcohol have such a powerful grip on us? How much of our relationship with this drug is written in our genes? What are the real dangers of our children drinking too young? Addiction expert John Marsden, who likes a drink, makes a professional and personal exploration of our relationship with alcohol. He undergoes physical and neurological examinations to determine its impact, and finds out why some people will find it much harder than others to resist alcohol. Even at the age of 14 there may be a way of determining which healthy children will turn into addicts. John experiments with a designer drug being developed that hopes to replicate all the benefits of alcohol without the dangers. Could this drug replace alcohol in the future?

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 unlocking their mysteries. It's a story that takes us into the heart of a black hole and to the very edge of what we think we know about the universe.

The intriguing possibility of life on Mars has fuelled man's quest to visit the Red Planet. Drawing on 45 years of Horizon archive, space expert Dr Kevin Fong presents a documentary on Earth's near neighbour.
Man's extraordinary attempts to reach Mars have pushed technological boundaries past their limit and raised the tantalising prospect of establishing human colonies beyond our own planet.
While the moon lies 240,000 miles away, Mars is at a distance of 50 million miles. Reaching the moon takes three days, but to land on Mars would take
nearly eight months, and only two thirds of the missions to Mars have made it.
The BBC has been there to analyse the highs and lows - including the ill-fated British attempt, the Beagle.
Horizon has explored how scientists believe the only way to truly understand Mars is to send people there. If and when we do, it will be the most challenging trip humanity has ever undertaken.

In a Horizon special, naturalist Sir David Attenborough investigates whether the world is heading for a population crisis.
In his lengthy career, Sir David has watched the human population more than double from 2.5 billion in 1950 to nearly seven billion. He reflects on the profound effects of this rapid growth, both on humans and the environment.
While much of the projected growth in human population is likely to come from the developing world, it is the lifestyle enjoyed by many in the West that has the most impact on the planet. Some experts claim that in the UK consumers use as much as two and a half times their fair share of Earth's resources.
Sir David examines whether it is the duty of individuals to commit not only to smaller families, but to change the way they live for the sake of humanity and planet Earth.

Research into dogs is gaining momentum, and scientists are investigating them like never before. From the latest fossil evidence, to the sequencing of the canine genome, to cognitive experiments, dogs are fast turning into the new chimps as a window into understanding ourselves.
Where does this relationship come from? In Siberia, a unique breeding experiment reveals the astonishing secret of how dogs evolved from wolves. Swedish scientists demonstrate how the human/dog bond is controlled by a powerful hormone also responsible for bonding mothers to their babies. Why are dogs so good at reading our emotions? Horizon meets Betsy, the world's most intelligent dog, and compares her incredible abilities to those of children. Man's best friend has recently gone one step further - helping us identify genes responsible for causing human diseases.

Dr Susan Jebb takes a look through nearly fifty years of amazing BBC archive of mankind's relationship with what we eat, charting the shift from the malnutrition of the past to today's obesity epidemic.
This is the story of our attempt to control nature through the wholesale industrialisation of food production in our search for enough to eat, and the consequences of that massive shift in our diet on the shape of our bodies, and the diseases that kill us.
From the BBC's original eccentric scientist Magnus Pyke comparing the virtues of artificial additives to a Beethoven sonata, to the tragic side effects of diet pills, Horizon and the BBC have covered it all.
On her journey through the decades, Dr Jebb explores how scientists have played a crucial role both in transforming the way our food is produced, but also in attempting to understand the biological mechanisms that determine why it is that some of us have become so large.

Drug discovery often owes as much to serendipity as to science, and that means much is learnt about how medicines work, or even what they do, when they're taken. By investigating some of the most popular pills people pop, Horizon asks, how much can they be trusted to do what they are supposed to?

For centuries scientists have been attempting to come up with an elixir of youth. Now remarkable discoveries are suggesting that ageing is something flexible that can ultimately be manipulated. Horizon meets the scientists who are attempting to piece together why we age and more vitally for all of us, what we can do to prevent it. But which theory will prevail?
Does the 95-year-old woman who smokes two packets of cigarettes a day hold the clue? Do blueberries really delay signs of ageing or is it more a question of attitude? Does the real key to controlling how we age lie with a five-year-old boy with an extraordinary ageing disease or with a self-experimenting Harvard professor? Could one of these breakthroughs really see our lives extend past 120 years?

By our third year, most of us will have learned to count. Once we know how, it seems as if there would be nothing to stop us counting forever. But, while infinity might seem like an perfectly innocent idea, keep counting and you enter a paradoxical world where nothing is as it seems.
Mathematicians have discovered there are infinitely many infinities, each one infinitely bigger than the last. And if the universe goes on forever, the consequences are even more bizarre. In an infinite universe, there are infinitely many copies of the Earth and infinitely many copies of you. Older than time, bigger than the universe and stranger than fiction. This is the story of infinity.

There's something very odd going on in space - something that shouldn't be possible. It is as though vast swathes of the universe are being hoovered up by a vast and unseen celestial vacuum cleaner. Sasha Kaslinsky, the scientist who discovered the phenomenon, is understandably nervous: 'It left us quite unsettled and jittery' he says, 'because this is not something we planned to find'. The accidental discovery of what is ominously being called 'dark flow' not only has implications for the destinies of large numbers of galaxies - it also means that large numbers of scientists might have to find a new way of understanding the universe. Dark flow is the latest in a long line of phenomena that have threatened to rewrite the textbooks. Does it herald a new era of understanding, or does it simply mean that everything we know about the universe is wrong?
