This is the story of how our solar system will be transformed by the aging sun before coming to a spectacular end in about eight billion years. Astronomers can peer into the far future to predict how it will happen by analysing distant galaxies, stars and even planets in their final moments. 　　In this film, Horizon brings these predictions to life in a peaceful midwestern town th...

Horizon looks at dark energy - the mysterious force that is unexpectedly causing the universe's expansion to speed up. The effects of dark energy were discovered in 1998 but physicists still don't know what it is. Worse, its very existence calls into question Albert Einstein's general theory of relativity - the cornerstone of modern physics. The hunt for the identity of dark en...

Alice Roberts explores the latest discoveries in the study of human origins, revealing the transformation that has been brought about in this field by genetics. 　　Traditional paleo-anthropology, based on fossils, is being transformed by advanced genome sequencing techniques. We now know that there were at least four other distinct species of human on the planet at the same time a...

Dr Michael Mosley seeks to establish the truth about meat. Are those barbecue favourites like burgers and sausages really that bad? Should we all go vegetarian instead? 　　Michael uncovers the latest science and puts it to the test on a high-meat diet. Will eating beef and bacon every day be bad for him? What meat should a healthy carnivore be buying?

Dr Michael Mosley seeks to establish the truth about meat. Every year, humans raise and eat 65 billion animals - nine animals for every person on the globe. In this eye-opening documentary, Michael examines the impact that this is having on the planet and finds out what meat eco-friendly carnivores should be buying. Is it better to buy free-range organic or factory-farmed meat?...

从保龄球大小的冰雹到扭曲的龙卷风，地球上的天气可以说是无奇不有，但即使是我们见过的最极端的天气也无法和太阳系其他行星或宇宙中数百万光年以外的行星上的天气相比。通过参观先进的实验室和使用神奇的CGI图像，《地平线》将再现这些行星上的天气，并构建出一个任何科幻小说作者都无法想法的世界。

The Ebola virus. No-one knows exactly where it comes from but one thing is certain - it's one of the most virulent infections known to science. This special episode of Horizon meets the scientists and doctors from all around the world looking for the cure and hears first-hand accounts of what it's actually like to catch - and survive - this terrible disease.

Dr Michael Mosley and Professor Alice Roberts investigate if male and female brains really are wired differently. 　　New research suggests that the connections in men and women's brains follow different patterns, patterns which may explain typical forms of male and female behaviour. But are these patterns innate, or are they shaped by the world around us? 　　Using a team of human lab...

Changes to the bacteria that live inside all of us are responsible for increasing the number of people with allergies, suggests new research. 　　In this episode of Horizon, the show investigates this claim by conducting a unique experiment with two allergic families in order to find out just what it is in the modern world that is to blame. With a raft of mini cameras, GPS units an...

The team investigate the use of modern medical technology to scan Egyptian animal mummies from museums across the world. By creating 3-D images of their content, experts are discovering the truth about the strange role animals played in ancient Egyptian belief. 　　This episode of Horizon meets the scientists working in Egypt who are exploring the ancient underground catacombs wher...

Horizon reveals how new archaeological discoveries are painting a different picture of the very first native Britons. For centuries it's been thought that these hunter-gatherers lived a brutal, hand-to-mouth existence. But extraordinary new evidence has forced scientists to rethink who these people were, where they came from and what impact they had on our early history. 　　Now, o...

Michael Mosley puts himself through a battery of health tests available to people who feel perfectly well. From an expensive heart scan to a new national screening procedure to detect the earliest signs of bowel cancer, Mosley sets out to discover which if any of the tests are worth doing.

New planets are now being discovered outside our solar system on a regular basis, and these strange new worlds are forcing scientists to rewrite the history of our own solar system. Far from a simple story of stable orbits, the creation of our solar system is a tale of hellfire, chaos and planetary pinball. 　　It's a miracle our Earth is here at all.

自从人类文明伊始酒精就被用作一种药物，但是关于酒精的科学似乎含糊不清而且充满了矛盾。我们对市售药品及其疗效相对比较熟悉，但是对其作用原理及对人体的影响却所知甚少。我们将调查有关酒精的证据，很多人认为每天适度饮酒对我们的身体健康不会产生太大影响，许多人认为每天少量饮酒其实对人体健康是有益的。而我们很多人喝酒不是这样，不是每天少量饮酒而是平时几乎滴酒不沾，到周末的时候才豪饮两三次；或者是邀上好友共进晚餐喝大量的葡萄酒；或者喝些鸡尾酒或烈酒。豪饮的危害到底有多大呢？我们马上来揭晓答案…

In 2014, the International Space Station had to move three times to avoid lethal chunks of space debris and there is an increasing problem of satellites mysteriously breaking down. With first-hand accounts from astronauts and experts, Horizon reveals the scale of the problem of space junk. Our planet is surrounded by hundreds of millions of pieces of junk moving at 17,000 miles...

Most of us think that Obsessive Compulsive Disorder (OCD) is just over fussy tidying. But it's actually much more serious. Sophie has to check that she hasn't killed people, looking for dead bodies wherever she goes, Richard is terrified of touching the bin, and Nanda is about to have pioneering brain surgery to stop her worrying about components on her body - that her eyebrow ...

Imagine a world where dinosaurs still walk the earth. A world where the Germans won World War II and you are president of the United States. Imagine a world where the laws of physics no longer apply and where infinite copies of you are playing out every storyline of your life. 　　It sounds like a plot stolen straight from Hollywood, but far from it. This is the multiverse. 　　Until v...
