Every second of your life you are under attack. Bacteria, viruses, spores and more living stuff wants to enter your body and use its resources for itself. The immune system is a powerful army of cells that fights like a T-Rex on speed and sacrifices itself for your survival. Without it you would die in no time. This sounds simple but the reality is complex, beautiful and just awesome. An animation of the immune system.

Finding alien life on a distant planet would be amazing news - or would it? If we are not the only intelligent life in the universe, this probably means our days are numbered and doom is certain.

Everybody is talking about Measles – but what does the virus actually do in the body? Is it really so harmful that you need a vaccination? We go deep into the body of an infected person and see what Measles does and how the immune system reacts to it!

Consciousness is perhaps the biggest riddle in nature. In the first part of this three part video series, we explore the origins of consciousness and take a closer look on how unaware things became aware.

Modern life would be impossible without plastic – but we have long since lost control over our invention. Why has plastic turned into a problem and what do we know about its dangers? This video is a collaboration with UN Environment and their Clean Seas campaign, If you want to take action to turn the tide on plastics, go to http://www.cleanseas.org and make your pledge.

Everybody is familiar with the feeling that things are not as they should be. That you are not successful enough, your relationships not satisfying enough. That you don’t have the things you crave. In this video we want to talk about one of the strongest predictors of how happy people are, how easily they make friends and how good they are at dealing with hardship. An antidote against dissatisfaction so to speak: Gratitude.

In December 2019 the Chinese authorities notified the world that a virus was spreading through their communities. In the following months it spread to other countries, with cases doubling within days. This virus is the “Severe acute respiratory syndrome-related coronavirus 2”, that causes the disease called COVID19, and that everyone simply calls Coronavirus.

Since the Industrial Revolution, humans have released over 1.5 trillion tonnes of carbon dioxide or CO2 into the earth's atmosphere. In the year 2019 we were still pumping out around 37 billion more. That’s 50% more than the year 2000 and almost three times as much as 50 years ago. And it’s not just CO2. We’re also pumping out growing volumes of other greenhouse gases such as methane and nitrous oxide. Combining all of our greenhouse gases, we’re emitting 51 billion tonnes of carbon dioxide equivalents each year. And emissions keep rising – but they need to get down to 0!

The sun. Smooth and round and peaceful. Except when it suddenly vomits radiation and plasma in random directions. These solar flares and coronal mass ejections, or CMEs can hit earth and have serious consequences for humanity.

By the end of the 21st century, humanity is becoming desperate. Decades of heatwaves and droughts have led to unusually poor harvests, while the warming oceans yield fewer fish each year. In the tropical zones, millions suffer from famine and resource wars have made millions more flee to the north. As things quickly get worse, in an act of desperation, the world's governments decide to enact an emergency plan...

Planet Earth grows to outlandish proportions that causes lying down to become the new standing up, the sun gets big ideas giving us a 20,000-year winter before blowing up in the biggest explosion since the big bang, we meet a dog the size of a dinosaur and Joe himself turns into a 49ft giant.
Dr Helen Czerksi explores the extraordinary science of heat. She reveals how heat is the hidden energy contained within matter, with the power to transform it from one state to another. Our ability to harness this fundamental law of science has led to some of humanity's greatest achievements, from the molten metals that enabled us to make tools, to the great engines of the Industrial Revolution powered by steam, to the searing heat of plasmas that offer almost unlimited power.

Physicist Dr Helen Czerski explores the narrow band of temperature that has led to life on Earth. She reveals how life began in a dramatic place where hot meets cold, and how every single living creature on Earth depends on temperature for its survival. She uncovers the extraordinary natural engineering that animals have evolved to keep their bodies at the right temperature. And she witnesses the remarkable surgery that's using temperature to push the human body to the very brink of life.

When we look at the sky, we have a flat, two-dimensional view. So how do astronomers figure the distances of stars and galaxies from Earth? Yuan-Sen Ting shows us how trigonometric parallaxes, standard candles and more help us determine the distance of objects several billion light years away from Earth.
Join scientists as they grab light from across the universe to prove quantum entanglement is real. Einstein called it "spooky action at a distance", but today quantum entanglement is poised to revolutionize technology from computers to cryptography. Physicists have gradually become convinced that the phenomenon two subatomic particles that mirror changes in each other instantaneously over any distance is real. But a few doubts remain. NOVA follows a ground-breaking experiment in the Canary Islands to use quasars at opposite ends of the universe to once and for all settle remaining questions.
