What is dark energy? What is dark matter? Well, if we knew exactly we would have a nobel prize – we know that they exist though. So what do we know about those strange things?

We are so used to some things that we stopped wondering about them. Like light. What is light? Some kind of wavy thing, right? Kind of.

Atoms are very weird. Wrapping your head around exactly how weird, is close to impossible – how can you describe something that is SO removed from humans experience? But then again, they kind of make up everything, so let us try anyways.

Time makes sense in small pieces. But when you look at huge stretches of time, it's almost impossible to wrap your head around things.

What is something? On the most fundamental level thinkable, what are things? Why are things? And why do things behave the way they do?

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.

Is there a border we will never cross? Are there places we will never be able to reach, no matter what? It turns out there are. Far, far more than you might have thought…

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.

Organic food is a huge trend: it promises a healthier and better life. But can Organic food really live up to the expectations or is it just baloney?

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!

Everybody feels lonely sometimes. But only few of us are aware how important this feeling was for our ancestors - and that our modern world can turn it into something that really hurts us. Why do we feel this way and what can we do about 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.

How does Fusion Energy work and is it a good idea?
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.

One of the key players of our immune system is the complement system. An army of millions and trillions of tiny bombs, which work together in a complex and elegant dance to stop intruders in your body.

Humans. We have been around for a while now. When we think about our past we think about ancient civilizations, the pyramids, stuff like that. But this is only a tiny, tiny part of our history.

Neutron stars are one of the most extreme and violent things in the universe. Giant atomic nuclei, only a few kilometers in diameter but as massive as stars. And they owe their existence to the death of something majestic.

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.

Somewhere in your body, your immune system just quietly killed one of your own cells, stopping it from becoming cancer, and saving your life. It does that all the time. The vast majority of cancer cells you develop will be killed without you ever noticing. Which is an incredibly hard job because of what cancer cells are: parts of yourself that start to behave as individuals even if it hurts you. What is cancer and how does your body kill it all the time?

The universe isn't just a vast empty ocean sprinkled with galaxies – most of the atoms are actually drifting in between, in the intergalactic medium. If we look closely, we can see who is in charge here: Quasars, the single most powerful objects in existence. As small as a grain of sand compared to the amazon river, they reside in the centers of some galaxies, shining with the power of a trillion stars, blasting out huge jets of matter, completely reshaping the cosmos around them. They are so powerful that they can kill a galaxy. What are they, and how do they mold the structure of the universe at their whim?
