Episodes:
-
Ep. 1: Horizon Christmas Special: Hand me my Sword, Humphrey
It is Christmas Day in the house of Hastings. The time (the 1830s), the place (a suburban Victorian home), and the atmosphere (after the pudding with the children waiting to be entertained) are ripe for father to stun his audience with his knowledge of the world of natural philosophy. It is a world of exploding biscuit tins, unpredictable hard-boiled eggs, singing drainpipes, and enough amateur science to make young enthusiasts reach for their bunsen burners, and mothers for their smelling salts.

Archeologists record the Ice Maiden's height, and discover a hole in her skull and peat packed in her body. *They use radiocarbon dating, tree-ring chronology and biological testing to determine the age of the remains and time of death. *The body is excavated and taken to Moscow for preservation and facial reconstruction. Another mummy, and other skeletons, are discovered elsewhere. *The program concludes by raising the question of who has rights to the ancient graves.
-
Ep. 28: Ice 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.
-
Ep. 29: Ice Mummies: Frozen in Heaven
This is the bizarre and fascinating story of the remains of Inca culture, frozen for posterity high in the mountains of the Andes. Evidence has emerged of sacrifice to the mountain gods, whose existence dominated the civilization over 500 years ago. The film traces the frozen bodies of children uncovered by archaeologists in South America, and follows an archaeological expedition to a high-altitude sacred site in search of ritual remains and another body. How did they come to be there? Why did they go to their deaths willingly? What was the religious framework that dictated their sacrifice to fierce gods?

-
Ep. 52: Lost Horizons: The Big Bang
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.
-

-
Ep. 56: Pandemic: A Horizon Guide
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.
-
Ep. 57: Mars: A Horizon Guide
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.
-
Ep. 58: How Many People Can Live on Planet Earth?
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.
-
Ep. 59: Diet: A Horizon Guide
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.
-
Ep. 60: The End of God? A Horizon Guide to Science and Religion

-
Ep. 62: Japan Earthquake: A Horizon Special
Professor Iain Stewart examines the powerful geological forces that unleashed the devastating Japanese earthquake, and explores how the release of this power of the planet brought Japan to the brink of a nuclear meltdown. He follows moment by moment how the earthquake was generated under the Pacific Ocean, travelled to the Japanese mainland, and the rare conditions that unleashed a tsunami. He also reveals the latest science behind earthquakes - from why we can't predict them, to what causes some of them to reach such power. Iain shows why our civilisation has developed such a dangerous relationship with earthquakes, and why millions of us continue to live in earthquake zones across the world.
-
Ep. 63: The Space Shuttle: A Horizon Guide
In 2011, after more than 30 years of service, America's space shuttle will take to the skies for the last time. Its story has been characterised by incredible triumphs, but blighted by devastating tragedies - and the BBC and Horizon have chronicled every step of its career.

-
Ep. 67: The Hunt for Higgs: A Horizon Special
Horizon goes behind the scenes at CERN to follow one of the most epic and expensive scientific quests of all time: the search for the Higgs particle, believed to give mass to everything in our universe. However, the hunt for Higgs is part of a much grander search for how the universe works. It promises to help answer questions like why we exist and is a vital part of a Grand Unified Theory of nature. At the heart of the pursuit of the elusive particle is the same feature that makes snowflakes beautiful and human faces attractive: the simple and enchanting idea of symmetry.
-
Ep. 68: Woof! A Horizon Guide to Dogs
Dallas Campbell looks back through the Horizon archives to find out what science can tell us about our best friend the dog, and whether new thinking should change the way we treat them.

Ep. 112: The Life and Times of El Niño
The Life and Times of El Niño combines history and science to show how this meteorological monster has affected global economy and political history. As a little understood climatic event, El Niño has caused the worst ever yellow fever epidemic in America, cannibalism in China, and in more recent times, the erosion of the coral reef in Australia and severe flooding in Brazil. But, as our knowledge of El Niño grows and attempts are made to predict its worldwide effects, The Life and Times of El Niño asks - could the power of one of nature's most destructive occurrences ever be contained? The Life and Times of El Niño is a science education resource investigating both the history and science of this climatic event.

Ep. 113: Impact! A Horizon Guide to Plane Crashes
It's a macabre paradox, but almost every advance in aviation safety has been driven by a crash. After every crash, investigators determine its cause and scientists make every effort to ensure the same mistakes never happen again. Dallas Campbell delves into the Horizon archives to chart the deadly disasters that have helped make air travel today the safest it has ever been.

Ep. 114: Impact! A Horizon Guide to Car Crashes
In the 1950s up to 8,000 people died every year on the roads in this country - a truly horrific figure. Thankfully it has now fallen to around 2,000 a year - still a terrible toll, but a vast improvement, particularly given the increase in cars on the road. Dallas Campbell looks back over decades of Horizon and BBC archive to chart the key scientific breakthroughs that have transformed road safety and saved millions of lives. However, it hasn't all been about innovative engineering and groundbreaking medical discoveries - scientists have also had to act as campaigners, persuading car manufacturers to install their life saving devices and urging the public to use them.

Ep. 115: Cat Watch 2014 - A Cat's Eye View
Playful pets, fearsome fighters or deadly hunters? Millions of us have cats in our homes, yet we know very little about them. In this series, Liz Bonnin joins forces with some of the world's top cat experts to conduct a groundbreaking scientific study. With GPS trackers and cat cameras, we follow 100 cats in three very different environments to find out what they get up to when they leave the cat flap. In the first programme we discover how our cats see, hear and smell the world with the senses of their wild ancestors, and why this could be making life difficult for them in the modern world.

Ep. 117: Cat Watch 2014 - Cat Talk
In the final episode of this groundbreaking scientific study, Liz Bonnin and a team of scientists reveal the secret language of our cats, the surprising conversations they have when we are asleep, and why they meow to us but not each other. We rig a house with cameras and cat trackers to discover if four cats living under one roof all get on as well as we would like to think. And we find out why living alongside us is making life difficult for our 21st-century cats.

Ep. 118: What's The Right Diet For You? Part 1
Instead of reaching for the latest fad diet, the best way to lose weight successfully is a personalised approach - diets tailored to your individual biology and psychology. In a groundbreaking national experiment, Dr Chris van Tulleken and Professor Tanya Byron join a team of leading experts to put 75 overweight volunteers on diets designed to tackle the specific reasons why they eat too much. The volunteers are put through a series of tests at a residential clinic to understand how their genes, hormones and psychology influence their eating behaviour. They are then put on the diets the experts believe are best suited to them. Can science succeed where other diets have failed?

Ep. 119: What's The Right Diet For You? Part 2
It is time to see if personalised dieting will work in normal life. The volunteers have been given one of three diets to follow - based on their genes, their hormones and their psychology. But now they are back at home, trying to stick to their personalised diets with all the stresses and temptations of real life. Dr Chris van Tulleken and Professor Tanya Byron discover how our genetic makeup can make temptation difficult to resist, how understanding the brain reveals what makes us comfort eat and what science can tell us about why we make disastrous food choices.

Ep. 122: Alastair Campbell: Depression and Me
In an intensely personal and often surprising film for BBC Two, Alastair Campbell candidly talks about his experience living with depression and explores if radical new treatments can make a difference. Alastair is best known for his role as Tony Blair’s formidable and often contentious spin doctor, but, away from the public eye, he has been dogged by crippling bouts of depression for most of his life. Some days, just getting out of bed is too hard. Therapy and anti-depressant medication is helping him keep his head above water, but is that really the best he can hope for? Encouraged by his family, Alastair sets out on a journey to explore if cutting edge science can offer him - and the millions of people like him - the hope of one day living depression-free. As he tries to understand his depression better, he also reflects on key events in his life and asks if they could have had a negative effect on his mind.
