Saddam'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.

The 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.

Living 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. His sleep is restless, with vivid nightmares when he is able to hear his surroundings while seeing terrifying hallucinations.

The Demonic Ape
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.

The Moscow Theatre Siege
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.

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

The hunt for the identity of Dark Energy is on, and although experiments conducted on earth and in space generate data that might provide a clue, physics is hoping another Einstein might emerge and write a new theory that explains the mystery.

Clean Eating: The Dirty Truth
Imagine if the food you eat could 'clean' your body and make you feel well. Dr Giles Yeo investigates the latest diet craze and social media sensation - clean eating. In a television first, Giles cooks with Ella Mills, the Instagram entrepreneur behind Deliciously Ella, one of the most popular brands associated with clean eating, and examines how far her plant-based cooking is based on science. She tells him clean has lost its way: "Clean now implies dirty and that's negative. I haven't used it, but as far as I understood it when I first read the term, it meant natural, kind of unprocessed, and now it doesn't mean that at all. It means diet, it means fad". Giles sifts through the claims of the Hemsley sisters, who advocate not just gluten-free but grain-free cooking, and Natasha Corrett, who popularises alkaline eating through her Honestly Healthy brand. In America, Giles reveals the key alternative health figures whose food philosophies are influencing the new gurus of clean. He discovers that when it comes to their promises about food and our health, all is not always what it appears to be. Inside a Californian ranch where cancer patients have been treated with alkaline food, Giles sees for himself what can happen when pseudoscience is taken to a shocking extreme.

Hair Care Secrets
The Horizon team have gathered together a team of scientists and doctors to investigate the incredible, natural material that is growing out of our heads - our hair. With access to the research laboratories of some of the world's leading hair care companies, including L'Oreal and ghd, the team explore the latest cutting-edge research and technology designed to push the boundaries of hair and hair care. Each one of us has a unique head of hair - an average of 150,000 individual hair strands growing approximately one centimetre every month. Over your lifetime, that is over 800 miles. The time and effort we put into styling, sculpting and maintaining this precious material has created a global hair care market worth a staggering £60 billion pounds. With such high stakes, it is inevitable that when developing hair-care products, science and business operate hand in hand. The team reveal how this industry science compares to the rigorous academic standards that they are used to. These investigations also reveal why we care so much about our hair, and whether or not it is worth splashing out on expensive shampoos. They uncover the magic ingredients found in conditioners and lay bare the secrets of the shiny, glossy hair seen in the adverts.
