The stories of mountaineers who have reached the summit of the world's tallest mountain, including a look at the dangers of the low oxygen levels at high altitudes. The programme examines the factors that allowed Edmund Hillary and Tenzing Norgay's 1953 expedition to succeed where so many had failed, and reveals how the Sherpas, who work as porters and guides for expeditions, have a physiology uniquely adapted to surviving at high altitudes.

NASA launches its most ambitious hunt for traces of life on Mars, landing a car-sized rover in a rocky, ancient river delta. The rover will stow samples for possible return to Earth and test technology that may pave the way for human travel to Mars.
In this third Horizon special, Dr Chris Van Tulleken is joined by his brother Xand and Dr Guddi Singh to take us through the latest developments and answer current concerns. Though the effect of the coronavirus pandemic has been devastating to many, the team reveal the breakthroughs in genetics, medicine and modelling that have provided a way out of this situation and given hope and confidence that, in the event of a future pandemic, we can take it on and win.
Chocolate reduces stress. Fish stimulates the brain. Is there any truth to such popular beliefs? The findings of researchers around the world say yes: It appears we really are what we eat. A study in a British prison found that inmates who took vitamin supplements were less prone to violent behavior. And in Germany, a psychologist at the University of Lübeck has shown that social behavior is influenced by the ingredients consumed at breakfast. But what really happens in the brain when we opt for honey instead of jam, and fish rather than sausage? Scientists around the world are trying to find out. Neuro-nutrition is the name of an interdisciplinary research field that investigates the impact of nutrition on brain health. Experiments on rats and flies offer new insight into the effects of our eating habits. When laboratory rats are fed a diet of junk food, the result is not just obesity. The menu also has a direct influence on their memory performance. The role of the intestinal flora has been known for some time, but scientists are currently discovering other relationships. So-called "brain food" for example: The Mediterranean diet that’s based on vegetables and fish is said to provide the best nutrition for small grey cells. Omega-3 fatty acids, which are found in fish, for example, protect the nerve cells and are indispensable for the development of the brain - because the brain is also what it eats!

Scientists have started looking to the heavens and wondering what the weather might be like on other planets. Today, we are witnessing the birth of extra-terrestrial meteorology. They began with our solar system, sending spacecraft to explore its furthest reaches, and now the latest telescopes are enabling astronomers to study planets further afield. Our exploration of the universe is revealing alien worlds with gigantic storm systems that encircle entire planets, supersonic winds and extreme temperatures. On some planets, temperatures are so hot that the clouds and rain are believed to be made of liquid lava droplets, and on other planets it is thought to rain precious stones. We thought we had extreme weather on Earth, but it turns out that it is nothing compared to what's out there.
This episode continues the study of mammals, and particularly those whose young gestate inside their bodies. Attenborough asks why these have become so varied and tries to discover the common theme that links them. Examples of primitive mammals that are still alive today include the treeshrew, the desman and the star-nosed mole. Insect eaters vary enormously from the aardvark, giant anteater and pangolin to those to which much of this programme is devoted: the bats, of which there are nearly 1,000 different species. These took to flying at night, and its possible that they evolved from treeshrews that jumped from tree to tree, in much the same way as a flying squirrel.
Our ability to see and record live events from right across the world has shrunk the globe, making virtual neighbours of us all. It is a defining characteristic of our modern world. The final episode in the series reveals the fascinating stories that made such everyday miracles possible. It tells the story of the handful of extraordinary inventions and their inventors who tackled the complexities of chemistry and electronics and discovered how to capture and reproduce still and moving images. Michael Mosley and academics Prof Mark Miodownik and Dr Cassie Newland tell the amazing story of three of the greatest and most transformative inventions of all time - photography, moving pictures and television.
Could a machine replace your doctor? Dr Hannah Fry explores the incredible ways AI is revolutionising healthcare - and what this means for all of us. This film chronicles the inside story of the AI health revolution, as one company, Babylon Health, prepare for a man vs machine showdown. Can Babylon succeed in their quest to prove their AI can outperform human doctors at safe triage and accurate diagnosis?

In the first of this three-part series investigating consumer spending, Jacques reveals how the concept of 'product lifespan' holds the key to our ever-churning consumerism. Exploring the historical origin of planned obsolescence, when some of the world biggest electrical manufacturers formed a light bulb cartel in the 1920s, Jacques reveals how products that are essential to our modern lifestyles are still made to break. During his investigation, Jacques uncovers the process by which a crucial transformation happened and attitudes towards spending were transformed. Instead of needing new goods because our old ones were broken, we learned to want them for reasons of fashion and aspiration - awaking a consumer appetite that could never be satisfied. In the US, he visits a recycling centre where brand-new high-tech goods are destroyed before they have even come out of the box. Jacques also meets some of the companies that encourage consumers to be dissatisfied with what they have and encourage purchases as part of an ever-faster cycle of 'upgrades'. He asks a senior IKEA executive why, despite the company's commitment to sustainability, it still encourages repeated discarding and purchasing. Jacques also talks to a former senior Apple employee who reveals how the company's new focus on fashion, with its colourful iPhones, keeps us buying even when technological innovation slows.

How will we power the planet without wrecking the climate? Five years after the earthquake and tsunami that triggered the unprecedented trio of meltdowns at the Fukushima Daiichi nuclear power plant, scientists and engineers are struggling to control an ongoing crisis. What’s next for Fukushima? What’s next for Japan? And what’s next for a world that seems determined to jettison one of our most important carbon-free sources of energy? Despite the catastrophe—and the ongoing risks associated with nuclear—a new generation of nuclear power seems poised to emerge the ashes of Fukushima. NOVA investigates how the realities of climate change, the inherent limitations of renewable energy sources, and the optimism and enthusiasm of a new generation of nuclear engineers is looking for ways to reinvent nuclear technology, all while the most recent disaster is still being managed. What are the lessons learned from Fukushima? And with all of nuclear’s inherent dangers, how might it be possible to build a safe nuclear future?

This week we are exploring Romania's largest and most iconic region,mistaken by many Americans and others as a country in its own right. In fact Transylvania is a name that most of the western world still associates with Dracula, werewolves and folk legend. But this land beyond the forest defies all preconceptions and remains one of the most culturally important and beautiful parts of Eastern Europe.
Where is the population in the world the smallest? What countries have the least people? It’s not the size that matters, and with countries, that is often the case. Some of the least populated countries in the world are also the wealthiest in terms of personal wealth and gross national product. And some of the larger nations have problems equally as huge to address. Some of these smaller countries are thinly populated because they are super-difficult to get to or sit in some of the world’s harshest regions. Some simply get by on one or two key industries and foreign aid. Some were used as strategic bases during war time. Some are playgrounds for the rich and famous. And one is reserved for holy activities. Today we take a closer look at the smallest of these nations, in this episode of the Infographics Show, The Ten Least Populated Countries in the World.
