Where are the limits of human technology? And can we somehow avoid them? This is where quantum computers become very interesting.

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.

A war has been raging for billions of years, killing trillions every single day, while we don’t even notice. This war involves the single deadliest being on our planet: The Bacteriophage.

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...

The largest things in the universe are black holes. In contrast to things like planets or stars they have no physical size limit, and can literally grow endlessly. Although in reality specific things need to happen to create different kinds of black holes, from really tiny ones to the largest single things in the universe. So how do black holes grow and how large is the largest of them all?
Never before in human history have we been richer, more advanced or powerful. And yet we feel overwhelmed in the face of rapid climate change. It seems simple on the surface. Greenhouse gases trap energy from the Sun and transfer it to our atmosphere. This leads to warmer winters, harsher summers. Dry places become drier and wet places wetter. Countless ecosystems will die while the rising oceans swallow coasts and the cities we build on them.

Telescopes on six solar observation satellites are currently monitoring the sun. The satellites include Japan's Hinode and the SDO developed by the United States. Solar activity (flares, sunspots) is at its lowest since modern observation began - what implications does this have for our Earth?
If a massive asteroid collides with earth, it could end life on our planet as we know it; new discoveries and cutting-edge tech reveal just how close we are to apocalypse and what it would take for the world's leading space agencies to stop it.
The most amazing images of the universe captured by the space telescope, and a look at plans to launch a new and more advanced satellite in 2018. In this updated version of "Hubble's Amazing Journey” we reveal some of Hubble's latest observations: It has produced some of the most awe-inspiring images ever taken of the universe. But what is often forgotten about the Hubble Space Telescope is that after its launch 25 years ago it was originally labelled an embarrassing and expensive flop.

Last week we covered multiple star systems, but what if we added thousands or even millions of stars to the mix? A star cluster. There are different kinds of clusters, though. Open clusters contain hundreds or thousands of stars held together by gravity. They’re young, and evaporate over time, their stars let loose to roam space freely. Globular clusters, on the other hand, are larger, have hundreds of thousands of stars, and are more spherical. They’re very old, a significant fraction of the age of the Universe itself, and that means their stars have less heavy elements in them, are redder, and probably don’t have planets (though we’re not really sure).
A voyage a decade in the making, the New Horizons probe has travelled to the end of our Solar System to reveal a world unlike any other, Pluto. Now, as it heads deep into the Kuiper Belt, those responsible for its magnificent journey share their fears, joy and hope for this piano-sized explorer.
