This report explores the challenges and insights gained from deep drilling into the Earth. Researchers from Germany, France, and Italy emphasize the technical complexity and costs of these undertakings. The drill cores, made of rock or ice, serve as archives of Earth's history and enable the study of phenomena such as climate change.

A new lunar cycle begins with 95 planned missions over the next ten years, including contributions from smaller nations. Scientists want to know how humans can carve out a life on the moon. Could humans live there permanently? And who does the moon belong to? Salem Al Marri of the United Arab Emirates Space Agency explains the motivations and goals of this intensified lunar exploration.

The ancient Greeks practiced sortition as a cost-effective method to prevent corruption and abuse of power and to establish political equality. Although this idea resurfaced in the 19th century, modern societies have opted for elections as the means of selecting representatives.

A research team led by Israeli biologist Ron Milo has attempted to calculate the total mass of all living things on Earth by combining data from various fields of research. The challenges range from accurately estimating the fish population in the ocean to discovering previously unknown species on land.

Climate change could cause sea levels to rise by up to 20 millimeters per year by the end of the century, threatening island nations and major cities. Urban planner Heiner Haaß and architect Bjarke Ingels propose building on the water, with concepts like Oceanix City or floating structures in the Maldives.

Bodily data, from genes to the microbiome, could indicate diseases early if analyzed precisely. Computers and algorithms are needed to recognize patterns. In the US, skin cancer has been detected early using algorithms. The vision is a medical avatar that monitors our bodily data and warns us of health problems.

Mucus, a versatile substance in nature, fulfills various functions: It can glide, stick, select, and even serve as a protective or defensive weapon. The unique state of matter of mucus enables its diverse applications. Microbiologist Hans-Curt Flemming emphasizes the central role of mucus in the evolution of microorganisms.

Long considered clean and inexpensive, nuclear energy raises a major problem: ultimate radioactive waste. This waste must be buried underground for at least a million years—an eternity! How can we warn our descendants of the risk it represents? What pictograms could alert them to the toxic gift we are leaving them?

Life would be fantastic if we were never scared. We could cross deep ravines on tightropes, ski down the steepest mountainsides and feel fine. Unfortunately, fear runs deep inside us.

With global warming, the melting of the ice is accelerating. The Arctic is warming two to three times faster than the rest of the world. Having remained stable until recently, the Antarctic sea ice is now melting dramatically. What will be the consequences of this phenomenon for the environment and for human beings?

From birth we are surrounded by sounds which, often without our knowledge, influence our view of the world. But are our reactions to these sounds the same?

Although we are mostly optimistic about our own lives, we tend to be rather pessimistic when we consider the future of the world and the future of our society. How can we explain this apparent contradiction?

What's the recipe for making a song a global hit? Musicologists, brain scientists and professionals in the music industry are actively researching the 'magic formula' for the mega hit.

The universe is vast. So vast that it defies the imagination. To the point that we find it strange that we "Earthlings" are the only living beings to inhabit it. What, then, is the probability that extraterrestrials exist? What might they look like? Finally, wouldn't their existence force us to rethink our place in the cosmos?

Tea of coffee? Fish or meat? Every day human beings make around 200 decisions about what to eat. But what drivess these choices? Why do we eat what we eat?

Light, as both a wave and a particle, travels at a constant speed. A beam of light originating in the sun's interior reaches Earth after eight minutes and drives the life cycle through photosynthesis.

Drought and insects threaten forests. What can be done to save them? In northern France, researchers are trying to introduce plants native to the south. Across the Rhine, the Thünen Institute cultivates oak trees that are particularly resistant to insects, drought, and fungi.

Nobody likes dust. Attempts to get rid of it are futile; it always comes back. And that's a good thing! Because without dust and its superpowers, life on Earth would hardly be possible. Dust contributes to the formation of rain, it provides nutrients to the sea and the jungle, and it's our personal calling card. Come to think of it, dust might even be able to save the world.

To tackle climate change, one option is to artificially cool the Earth or capture CO2. The field of geoengineering is full of seemingly outlandish ways of manipulating the planet's climate.

The fact that we have a breathable atmosphere on Earth is largely down to algae. Could these aquatic plants be the secret of solving climate change and saving ourselves and the planet?

The sharpest weapon of the pandemic has given us a vaccination technique that almost no one knew about before the coronavirus—messenger RNA. It has been studied for over 20 years. The grand goal of mRNA pioneers: a cancer vaccine. After the success of coronavirus vaccines, will we also defeat this old sworn enemy of humanity? A small community of researchers from around the world has always believed in the revolutionary potential of mRNA vaccination. The rest of the scientific world considered the biomolecule a mere unstable diva until recently. "No one read our papers, and we didn't receive any research funding either," says Steve Pascolo, who likes to compare mRNA to the transcription of a recipe from the great cookbook of DNA. A transcription that can be delivered to the kitchens of cells, which then do everything indicated in the recipe. The human body becomes a pharmacy.

Giving up flying overnight would cause global logistical problems, as many delivery chains would be interrupted. But planes are climate killers. So what should be done?

It is estimated that there are now more than 1.7 million robots with social capabilities in the world. They feed us, educate us, help us, and entertain us. Highly technical sex robots have existed for a long time. But can these machines actually develop feelings—or even experience love? "We have developed digital artificial hormones for our robot. And we are using artificial intelligence to simulate the changes in hormonal balance in a person who falls in love," explains Hooman Samani, a robotics developer at the University of Plymouth. Conversely, we are also moving closer to a human-machine relationship: For cognitive psychologist Martin Fischer of the University of Potsdam, certain psychological effects indicate that our attitude toward robots will become increasingly positive in the future.

Parasites get a bad rap: they can make us sick or even kill us. For centuries, we have been trying to protect ourselves against them, in particular through hygiene measures. Yet half of the living beings on Earth are parasites. If they are really everywhere, maybe they are not fundamentally useless?

We spend a third of our lives sleeping. Is it possible for us to sleep less and enjoy extra waking years for leisure and work? Can we optimise our sleep patterns to get more out of life?

In September 2021, El Salvador became the first country in the world to introduce Bitcoin as legal tender. From now on, all companies accept the cryptocurrency from their customers, as well as the US dollar. "A crazy idea," says former economist Peter Bofinger. The price of bitcoin is far too volatile, and it's a dangerous bet - one that the president thinks he can pull off.

Black holes can tell us a lot about the universe. But could they hold the key to understanding our world? Astrophysicist Nikodem Poplawski proposes that our universe may not have been born after a Big Bang after all. Perhaps our whole world is inside a black hole…

Humans spend up to six years dreaming over the course of their lifetime. What if dreams were more than unreal visions? Could we take the brilliant ideas that appear in dreams and make them a reality? Dreams hold a largely untapped creative potential.

Researchers are searching for patterns and models to predict migration. Factors such as technological developments, demographic changes, economic crises, and climate change influence migration.

The mystery of animal communication stands in contrast to human language: Elephants use infrasound, cats vocalize, and whales communicate through flipper movements. The question is, what would change if these sounds could be translated? Humans have the ability to understand each other using dictionaries or translation apps.

The Flynn effect showed an increase in intelligence scores since the 20th century. However, since the turn of the millennium, some IQ scores have been declining, and researchers are searching for explanations. Theories include "dysgenics," in which families with academic backgrounds tend to have fewer children, as well as the influence of migrants from disadvantaged backgrounds.

Let's not kid ourselves: everyone has biases. Whether it's filling a position, granting credit, or handing down a prison sentence, how can we be sure we're making rational decisions? Wouldn't it be wiser to rely on artificial intelligence, a technology already deployed in many cases with surprising results?

Modern, highly efficient agriculture feeds many people, but it is reaching its ecological limits with declining soil fertility and biodiversity, as well as increasing environmental pollution from chemicals. The challenges of climate change are exacerbating these problems.

Drugs have a bad press. But scientists have long been convinced that the use of psychedelics can sometimes be beneficial. The use of ecstasy, LSD and other hallucinogens could soon be authorised for therapeutic purposes. Should we change our relationship to certain drugs?

As soon as weightlessness sets in in Earth orbit, everything floats, including bodily fluids. Most astronauts suffer from space sickness – similar to seasickness. You get sick, your eyes go crazy, your face swells up, your legs get longer and after a few sleepless nights (there is no day or night in space) many astronauts get severe back pain. Space researchers are trying to understand how the human body reacts without gravity. Could we need it to live?

Brain researcher Gerhard Roth describes near-death experiences as frequent encounters with bright light and feelings of bliss. Scientists explain this through neurological processes and emphasize that those affected are often only clinically dead.

Humanity has dreamed of a Fountain of Youth since the dawn of time. A dream that may have become reality. Laboratories around the world announce they have rejuvenated animal species as diverse as mice, nematodes, and fruit flies. Anti-aging research has achieved the impossible: these animals live longer and healthier lives. Next step, human beings?

Both a blessing and a curse, farming feeds us humans but is also harmful to the environment. Agriculture has radically transformed the land and our ways of life. But could foodstuffs created with biotechnology spell the end of traditional farming?

We like to talk about the weather because it affects us every day. But have you ever heard of space weather? Not just for astronauts, it also our affects lives on Earth. Scientists are particularly interested in solar activity as it can quickly disrupt our life on Earth.

According to Elon Musk, we could soon be living on Mars. Yet, this idea seems unrealistic: extreme cold, an atmosphere composed primarily of CO2, and dangerous cosmic rays... So why on earth would anyone want to settle there? Where does this enthusiasm for the Red Planet come from?

Imagine a friend wants to borrow your car, you promise to provide one even though you only have a windscreen wiper. Absurd isn’t it? But this is exactly what banks do when they lend you money…

With over 13,000 nuclear weapons in the world, there is a risk of massive destruction. The program "42 – The Answer to Almost Everything" examines this topic scientifically.

Getting into space has never been easier and the resources of our solar system are highly coveted. But with the legal framework of space exploration and the exploitation of its resources still unclear, is space being stolen from us?

It has been known since antiquity that thoughts have an influence on health. Research, such as imaging techniques that demonstrate the placebo effect, makes the power of thought visible. Psychologist Ellen Langer shows in experiments how thoughts can influence the body. However, controlling thoughts is difficult because most of them are unconscious.

We cannot escape our fate and we cannot escape ourselves. But we also have our limits: confused thinking, misleading intuitions, unrealiable memories... What consequences do these potential errors have on our relationship to the world and to ourselves? Just how far can we trust ourselves?

Swarms are fascinating phenomena without clear leadership. In beehives, anthills, in the sky, or in the sea, they operate successfully and aesthetically. Human crowds, on the other hand, can become chaotic in lynch mobs or traffic jams. Researchers are investigating the rules behind swarm intelligence in order to learn from them and perhaps apply them to robot swarms.

Formulating the theory of everything, the one that would describe all the laws of the Universe from a single fundamental law, would be the pinnacle achievement of physics. We could finally understand everything and solve the mysteries that still escape us. Heisenberg, Einstein, Hawking… All the great scientists have tried. All have failed. So can we still hope to find the theory of everything one day?

Humanity has been hoping for a sensational discovery. Ever since we succeeded in converting wind and sun into energy, we've been waiting for the next big thing. A treasure just waiting to be discovered. The idea that we might find this in our feces seems far-fetched at first. We overlook its true potential. Research on our bodies is essential for modern medicine. Through it, immunologists and nutritionists receive messages from the mysterious core of our bodies. Doctors like gastroenterologist Harry Sokol in Paris go even further and utilize the healing capabilities of our stool. But our feces offer us other access points to ourselves. Based on ancient fecal discoveries from the past, we can travel back in time to our evolutionary history.

Psychopaths like Ted Bundy are not isolated cases; approximately 1-2% of the population are considered psychopathic. Psychologist Abigail Marsh researches why some adolescents with conspicuous behavior become psychopaths while others do not. Despite the complex causes, the psychopathy checklist can help identify them.

Every seven days, a large ship goes missing. This is due, among other things, to monstrous waves that appear out of nowhere. Unlike tsunamis, there is currently no method for warning or predicting them. This is because science still knows surprisingly little about the phenomenon of "freak waves." Rogue waves were long considered sailors' tales until a 26-meter-high wave was recorded on the Draupner platform in the North Sea in 1995. This changed research and led to three theories about their formation: the current model, superposition, and nonlinear modulation instability.

All living beings stop growing at some point. The global economy is different: it just keeps growing. Is a world without economic growth possible and what might that mean for the future?

Humans don't just play for fun, but also for evolutionary reasons. Playing helped hunter-gatherers develop important skills and understand their environment. With the rise of advanced civilizations, board games like chess and Monopoly emerged.

Usain Bolt ran 100 meters in 9.58 seconds, Petra Felke threw the javelin 80 meters. These are absolute limits that no one has been able to "break" to this day. Or rather: no human being. Because in the animal kingdom, there are creatures like the flea or the cat that are far superior to us. Why is that – and couldn't we learn from these animal specialists?

Energy from fossil fuels such as coal, oil, and gas made modern life possible in the first place; however, at the same time, it harms the climate and the environment. Can we find an energy source that provides just as much power and is always clean and available everywhere—a kind of perfect energy? In terms of energy density, nuclear power was considered the perfect energy source after its discovery. According to nuclear physicist Emmanuelle Galichet, just a few grams of uranium in nuclear fission are enough to generate as much energy as burning several tons of oil. However, as great as the benefits of nuclear power are, the risks are also significant, especially when it comes to storing highly radioactive nuclear waste. Isn't solar power the better choice?

As fascinating as they are frightening, sharks are now threatened. Of the 536 species known today, a third are endangered, mainly due to overfishing and environmental destruction. Can we still save sharks, or are they doomed to disappear?

For a long time, humanity was relatively unanimous: animals are little more than biological machines. This view has gradually changed, particularly with the pioneering work of the naturalist Charles Darwin: Darwin believed that consciousness is a fundamental property of life in general. In his view, even simple creatures have a rudimentary internal workings of feelings and impressions that are not so different from those of humans. But how can we know what animals really think and feel? You can't ask them, and you can't look inside their heads either. For a long time, researchers tried to solve the problem with the so-called mirror test: if a living being recognizes itself in a mirror, it must have self-confidence. Chimpanzees and dolphins pass the mirror test, but dogs do not. Does this mean that dogs are not self-aware?

When we're really in love, all hell breaks loose. The heart races, palms sweat, the mouth goes dry and the brain switches to "happily insane" mode. Some cultures are convinced that that's not a solid foundation to build a marriage and family on, opting for arranged partnerships instead. But romantic love evolved for a reason. If we loved each other in small groups, then males would know who they were related to, and would fight for them and their children.

"Be careful! It's precious!" – we've probably all heard such warnings as children, for example, when we wanted to examine our father's camera or an old vase. That's how we learned to be careful with valuable objects. Curiously, nature is different. Even though it's the most precious thing we have, we humans don't treat it well. Not only do we use it, but we abuse it. Would it be different if nature and its services received some kind of price? If all of nature's free services were also made economically visible? For example, it provides us with food and drink, all kinds of important materials, cools us in the heat, purifies our drinking water and the air we breathe. In short: nature guarantees our survival.

The search for artificial blood that could solve several problems, such as anemia, the risk of disease transmission, and the scarcity of different blood types, began in the 1960s with the belief in perfluorocarbons as a potential solution. However, the challenge of replacing all the functions of blood cells simultaneously proved practically impossible.

Dealing deeply with hate is no fun. But as with all unpleasant things, it helps to confront the issue rather than avoid it. In today's society, hate is hard to miss: hate messages against politicians, hatred of the social system, of the COVID-19 measures. Hate seems to be everywhere.

Researchers want to use cloning and gene editing to bring back lost species. If humanity played God by killing them off, some say we should also play God and put things right again. US Scientists claim that in just a few short years, they could bring back mammoths, which died out 4,000 years ago.

Andreas Weber, biologist and philosopher, argues for granting animals and plants the right to defend themselves in courts, based on their capacity for sentential treatment. Legal scholar Saskia Stucki sees the possibility of a change in the law. Ecuador was the first country to grant nature its own rights in its constitution.

We already see in everyday life how much colors control us: we're often warmer in a red down jacket than in the same down jacket in blue, reports fashion designer Jean-Gabriel Causse, a specialist in the effects of color. The fact that the color of a garment alone can improve our concentration, creativity, or even our health is another indication of the power of color. Colors control our attention, they affect our senses, and thus shape—consciously or unconsciously—our perception of the world. For neurobiologist Annette Werner, it's clear: colors play a crucial role in the development of life. Thanks to the green pigment chlorophyll, bacteria and plants were able to capture sunlight and convert it into energy and oxygen—the source upon which all life depends. In general, nature has used dyes as a means of communication for millions of years.

Modern civilization does not mean the end of evolutionary adaptation. Researchers like Frank Rühli observe ongoing changes, such as lactose tolerance. The question of whether a new human species could emerge is complex. Natural selection would take millions of years, but technologies like the CRISPR/Cas9 gene-editing tool could accelerate the process.

A man has enough sperm. Or so you might think - up to 600 million per ejaculation. And yet there is cause for concern: several studies have shown a significant decline in sperm count, especially in Western countries, in the last 50 years. Are we heading towards a sperm crisis?

Yes, urban life can make a crucial contribution to saving the planet, according to sustainability researcher Xuemei Bai. Compared to the suburbs, CO2 emissions are lower in cities and rural areas.

The fear that the sky could one day fall on our heads dates back to the dawn of time. The impact of an asteroid or a comet could dramatically change life on Earth in a fraction of a second. The dinosaurs were wiped out by one, and we might well one day share their fate.

What do we know about fungi? They are neither animals nor plants. Some are poisonous, many are delicious. But that was the main point. Fungi have barely been studied. They are among the oldest and most diverse life forms on our planet. Who knew that in primitive times, plants could only develop with the help of fungi? To this day, 90% of all plants depend on the close community of fungi. Fungi are everywhere. In the soil, in the air, in our bodies. They form immense networks. Researchers have nicknamed it the "Wood Wide Web." The fungal mycelium that grows underground is made up of what are called hyphae. They are five times thinner than a human hair and have very sensitive abilities to perceive their environment.

Pushing to the front of a line, parking a car quickly on a bicycle lane, occupying seats on a train that do not belong to you - almost everyone is confronted with selfish behavior at some point in their lives. While minor instances of selfishness can be easily forgotten, when it becomes extreme and individuals become egomaniacs, they can cause significant harm to those around them. The extent of these selfish tendencies depends partly on genetics, partly on upbringing, and ultimately on the situation, according to psychologist Anne Böckler-Raettig from the University of Würzburg. Psychologist Morten Moshagen highlights that a certain degree of egoism is even necessary for our mental well-being, and together with colleagues, he has developed the "Dark Factor Test" to measure the degree to which we operate within a healthy, egoistic framework, versus when our behavior turns into something harmful and evil.

The universe could be heading towards different scenarios, including the "Big Freeze" as it expands, cools, and disintegrates. Other possibilities include a collapsing universe (Big Crunch) or an accelerating expansion that eventually tears the universe apart (Big Rip). While many scenarios will take an unimaginably long time to occur, a sudden end cannot be ruled out.

From Armageddon to Extinction Rebellion, the end-of-the-world narrative is a socio-cultural phenomenon. The apocalypse has been predicted nearly 200 times in the last two millennia, roughly equivalent to an end of the world every ten years...

Is time travel just science fiction? Not quite: scientists from the fields of quantum physics, string theory, and astrophysics clearly demonstrate that time travel is theoretically possible—at least if it involves going into the future.

We can't see inside other people's minds, but we sometimes believe we can read their thoughts. When we talk to someone, our brain is working overtime, gathering countless pieces of information. But should we really trust it? And what might the consequences be if we're wrong?

Chemistry makes our sweaters softer, our world more colourful and pleasant, and it can even save lives. The flip side: we have released so many toxic chemicals that we have severely damaged our ecosystem. And these substances are increasing. Where are the limits of our Earth's capacity, and how do we get a handle on the poison?

Chance, destiny, predestination, God. People have come up with many explanations for events that either seem completely unbelievable or highly improbable. Albert Einstein said, God "does not play dice." Like many scientists since Newton, he was convinced that the world could, in theory, be calculated down to the smallest detail. In his view, there was no such thing as chance. Everything was merely an endless chain of cause and effect. So, if one had enough data, one could also predict the future. "Einstein was wrong," says quantum physicist and artist Libby Heaney. Because the tiniest particles in the world behave completely randomly. Have we just not yet deciphered their laws, or is our world fundamentally governed by chance?

The vast sea - a symbol of boundlessness. But is it really so? Who does the sea actually belong to? In the past, it was simple: as far as the cannons could shoot, that much sea belonged to the land. Nowadays, the distribution is more complicated, also because we use the sea in diverse and intensive ways. But can the sea and its treasures be distributed fairly at all?

The beauty of the peacock troubled Darwin for a long time. It didn't quite fit into his theory of evolution and the idea of "survival of the fittest." Darwin came to the conviction that animals must also possess a sense of beauty. Especially the females, who select the "beautiful" males. Modern-day ornithologist Richard O. Prum is convinced that "the complexity of aesthetic and sexual pleasure" in the animal kingdom is far more developed than we give it credit for.

Many researchers believe that we won't experience more and more wind in the world, but rather less and less. Indeed, if the ice melts at the poles and they warm up, the temperature difference between the equator and the poles will also decrease. Now, this temperature difference is the "engine" that drives our winds: warm, humid air rises at the equator and flows towards the poles, where it cools and descends. If this temperature difference decreases, there should therefore be less wind. And that's what happened: for decades, the wind slowly decreased. About ten years ago, the average wind speed increased again. Why is this happening? Climate research is still lost in conjecture.

Let's be honest: when we think about rising sea levels, we initially think that the water rises the same way all over the world—like in a bathtub. And if we're talking about an annual rise of about 4 millimeters, it seems harmless at first. But it's not that simple. There is a global average, which we find, for example, in the reports of the Intergovernmental Panel on Climate Change. But these reports also state that if we continue as we have been—and by that we mean the amount of greenhouse gas emissions released into the atmosphere—we could expect a sea level rise of up to one meter by the end of the century. This is no small matter when you consider that many coastal cities are only a few centimeters above sea level, and some are even below.

Most people can tell quite early on whether they are attracted to women or men. But what if our desire isn't as determined as we think? Are we all perhaps bisexual?

The dominance of our species has consequences: we have created conditions that fuel rapid evolution. Global warming, climate change, hunting, habitat destruction, resource exploitation, and pollution are forcing nature to adapt to rapidly changing conditions. As a result, new variants emerge within populations or even entirely new species, adapting to new circumstances within a few generations. Can this rapid evolution help us find a solution to the loss of species?

We've all experienced it: a name that slips our mind or a new password. Forgetting is annoying and sometimes embarrassing. But how does the brain decide what we forget? There's a kind of competition among our memories. Stronger, more repeated impressions prevail over weaker ones. But are these erased memories lost forever? This question has been the subject of debate for decades. But in recent years, a new idea has emerged! It's possible that memories still exist. "If we stimulate the cells, the memories become available again. So, memory survives the forgetting process, but it only re-emerges under the right conditions. In a sense, this could mean that we lose the address of the memory, but not the memory itself," explains neuroscientist Tomás Ryan. Could we one day recover all our memories?

Humans lie, deceive, and wage merciless wars. Sometimes it seems as if evil is typically human. On the other hand, humans can also be good, love, and even make peace with enemies. Which side within us is stronger? The good or the evil?

Humanity is dependent on electricity. Power outages have been rare for us so far, but our electricity system is being transformed: renewable energies are intended to replace the fossil fuels that have reliably supplied us. Additionally, the risks of natural disasters and cyberattacks are increasing. At the same time, our electricity demand is growing tremendously.

Glaciers are wonders of nature and tourist attractions, and they are also the largest reservoirs of drinking water on the planet. In fact, 70% of the world's freshwater resources are frozen as snow or ice. These "water towers" have a major impact on our lives.

Since the dawn of time, mankind has aspired to one thing only: to go further and further beyond the limits of what he knows. But how far is it possible to travel in space? Could we reach the stars?

From a very early age, we are instilled with the idea that lying is wrong. Yet learning to lie is a normal and necessary stage in our psychological development. What if lying made the world a better place?

Some people dream of being cryogenically frozen. It's a way to defy death, to come back when things are better, or simply to know what the Earth will look like in a hundred years. But don't you have to be a little crazy to want to lock yourself in a freezer? Is it possible to stay frozen like that for decades and pick up your life right where you left off?

Whether in mobile phones, glass or even in our underwear, sand is everywhere in our lives. Without it, there would be no houses and no roads. According to the UN Environment Programme, each person consumes around 17 kilograms of it every day, and our rising consumption is causing problems: Ecosystems around the world are being destroyed by sand extraction. But could we ever run out of sand?

Adults laugh 20 times a day, children up to 500 times. But where does humour begin and end? And why does someone find something funny that makes no one else laugh? Humour is eminently subjective and depends very much on the context. So can we give a general and definitive answer to the question What is funny? Behavioural psychologist Peter McGraw tackles the question.

While scientists agree on the date (4 billion years ago), their opinions diverge on the place and conditions that saw the birth of life on our planet. Did the first cells emerge from a primordial soup rather than from primitive oceanic hydrothermal springs? Or could life on Earth have originated elsewhere? 42 attempts to explain it all.

When we harm someone, we may be punished, the point of which is to be made aware of the harm we have done to others. So goes the theory. But researchers warn against the harmful effect of punishment, which they believe can lead to more crime. Could prison and fines have the opposite effect to the one intended?

We spend large stretches of our waking hours imagining things or just daydreaming. Why are we so often away in the clouds? What are our imaginations for?

Our genes determine many of our characteristics: our build, our height, the colour of our eyes or even our predisposition to music. Could it be possible to control the mechanisms that activate and inhibit our genes, as epigenetics seeks to do? Could this science make us more intelligent, more musically gifted or more athletic?

The biggest movement in our lives is one that we don't even notice: The continents of the earth are on the move, albeit in slow motion. For several decades now, humans have been developing an understanding of where this continental drift could lead: We are all moving towards a supercontinent that unites almost all the planet’s land masses. But what would life be like on this supercontinent called Amasia?

Every dog ​​owner knows this well: the relationship between humans and dogs is unique. A powerful and unbreakable bond, perhaps even love. No other animal is as close to its owner or adapts so well to human constraints. But what makes this relationship so special? Do dogs really love us? And if so, why?

Corruption has been part of society since the dawn of time, swallowing up colossal sums of money which could be spent on improving everyone’s lives. Is it possible to get rid of it once and for all? And could corruption be useful for society as a whole?

Vultures can spot a dead antelope from five kilometres away, while seals can dive into deep water, even under the ice. It is also said that many animals have a mysterious sixth sense: they can predict imminent natural disasters. Do animals access knowledge that is beyond humans? Are they cleverer than us?

The richest man in the world - Frenchman Bernard Arnault - is worth more than 200 billion euros. Around the world, the super rich are getting ever richer. Since money can buy power and influence. Are billionaires undermining democracy?

Words shape our thoughts. And it is most often in our mother tongue that we reflect, that we find the words to understand the world. How does our language of socialization change our perception of the world? Would we be a completely different person if we had a different mother tongue?

The idea that our universe isn't as unique as we think is not only captivating the imaginations of authors and filmmakers, but is also increasingly engaging researchers. The theories we use to explain the Big Bang also predict the formation of other parallel worlds. So, do we actually live in a multiverse?

Wars, pandemics, economic crises...: so many episodes during which we look back and wonder if history isn't repeating itself. But what is the reality? Indeed, certain geographical or psychological patterns favor the occurrence of similar events. But the stories humans tell themselves also contribute to these similarities between events. Not to mention our tendency to sometimes believe that history repeats itself when the differences outweigh the similarities. Can we, however, learn anything from history?

In a century, the number of humans on Earth has more than quadrupled, rising from nearly 2 billion to over 8 billion. Some believe this is far too many and that we are heading for disaster. Yet, the Cassandras of the 1960s were already saying the same thing when we were not even 4 billion. How many people can the Earth support?

The relationship between stress and humans is anything but a love affair. According to the WHO, 85% of us would prefer to do without this "disease of the 21st century." However, research tells us that it's not stress itself that makes us sick, but how we manage it. We might even need more stimulation, provided it's the right kind of stress! This kind of stress would then awaken our superpowers...

Humanity survived the last Ice Age as well as the plague that decimated half of Europe in the 1300s. But do disasters only bring death and suffering, or can they also have positive effects on our societies? Understanding the impact of disastrous historical events can reveal how adversity shapes human resilience, and perhaps even contributes to our evolution.

We still work in office buildings, buy our groceries at the supermarket and visit museums in the flesh. But soon, these activities could all shift to the metaverse – a virtual space envisioned by tech giants where avatars can live, work and move freely. This is how the metaverse could redefine our everyday lives and challenge our understanding of reality.

Stories of unrelated people who look exactly alike are common. While having a doppelganger could pose risks like identity theft, it can also be thrilling. Some people would love to meet their mirror image, but what are the odds of this happening?

Although our planet has already overcome numerous crises, Homo Sapiens have disrupted the natural world nature so much that scientists are now talking about a collapse in biodiversity. Could genome editing or synthetic biology save the planet's wildlife and ultimately save ourselves?

Periods of climate change in the past have caused mass extinctions. But they have also led to the emergence of new complex life forms. Understanding these historic shifts in our Earth’s climate may offer insights into the ecological challenges and environmental imbalances we are currently facing.

Depictions of the future in popular science fiction novels or films are often bleak, while positive utopias and tales of a new golden age are beginning to fade. Why is this shift taking place? Has our grim view of the world made us lose hope for a better future? And what does this say about our vision of what is to come?

Clouds carry water particles, which they release onto Earth as rain. However, the way they distribute water across the planet unfortunately leaves much to be desired: it often rains in areas that already have sufficient water reserves, while other regions remain dry. Could we change this?

Our view of sugar has changed drastically. Once seen as a healthy appetite suppressant in the 1960s, it's now linked to serious illnesses like obesity and diabetes. What is even more alarming is that it has the potential to affect our brains. Learn more about the latest research being done on this addictive substance and its true impact on our health and well-being.

In theory, it's simple: the North Pole is in the north, and the South Pole is in the south. And a compass needle always points north—or, more precisely, toward the magnetic North Pole, a point on Earth located not far from the geographic North Pole. But what would happen if things were to change? In fact, the magnetic North Pole is moving right now, and so rapidly that the Earth's magnetic field could well reverse: the magnetic North Pole would then find itself in the geographic south, and vice versa. This change won't happen overnight, of course, but if it does, won't humans and animals be completely disoriented?

Many people don't consider their sense of smell particularly important. However, if we had to give up one of our senses, surveys show that the majority choose their sense of smell. Twenty-five percent of the students surveyed would even rather lose their sense of smell than their smartphone. But we would lose more than we realize. Smells not only evoke memories, they also warn us of dangers and illnesses. They have power in our everyday lives. And we haven't yet fully explored this power – the potential of our sense of smell. It could also help us solve future challenges.

Do houseplants grow faster when we talk to them? Does a cactus get bored in a pot? Do plants have human senses that are comparable to ours and those of animals? For most plant researchers, one thing is clear: plants can perceive their environment and react to it, but not because of conscious behaviour. In this episode of 42 we explore plant life.

Like food, drink or sex, feeling valued is one of our most basic needs: we aspire to be loved, sometimes even adored. But why is that, and why doesn't it happen to everyone? Is it really a good thing to be popular?

From the sandbox to the office, power dynamics shape our lives. Power can change our personalities and make us take reckless risks, give in to impulses and even erode our empathy – a transformation that can open the door to conflict or war. The experience of power has far-reaching consequences, both on a personal and on a global scale.

Is human evolution the result of chance? Do living organisms necessarily evolve towards complexity?

Pain has a bad reputation, and we go to great lengths to avoid it: from painkillers to general self-care. It has even been said that our society rejects not only physical pain, but social pain as well. Despite our quest for pleasure, 42 asks the question: is pain necessary?

Societies built by humans, rarely seem to stand the test of time, whereas ants have been living in colonies since the dawn of time. Do animals build better societies? And should we draw inspiration from them?

Why is violence still so prevalent in our society, when the state is supposed to ensure everyone's safety? Is violence simply part of our nature? Or is it possible to live without violence?

Memory is our identity: our representation of the world, ourselves and others is based on what we remember. But is it possible to retain memories without distorting them? Because memory sometimes plays tricks on us: psychological experiments have shown that we sometimes remember things that actually never happened.

Beyond what human beings can see, exists something that makes up 80% of the universe. Scientists are convinced that dark matter assures the cohesion of our world. But how can you find a substance that gives off no light, reflects no light and has hardly any interaction with atoms?

Religious faith is in decline in Europe, and yet 70% of human beings in the world believe in the existence of one or many deities. Do human beings need God? Are we homo religious rather than homo sapiens?

All over the world, people are taking to the streets about injustice, freedom, and calling for more rights. But in this age of demonstrations, which protests work? And why?

You might think that children are small, unfinished people who don't yet understand the world. Perhaps this is where the potential for conflict between children and adults comes from. But could we have a lot to learn from children? And do they do some things better?

With the increase in the world population in recent decades, there have never been as many people living, but also dying, as today: Around 160,000 people pass away every day. These high numbers are a logistical problem as large cities run out of cemetery space and the carbon footprint of burial and cremation rises. So how will we bury and remember our dead, and also grieve in the future?

Every year, astronomical sums of money are spent worldwide on arms, when it would be a thousand times better to invest in eradicating hunger and poverty or funding the fight against climate change. In today's political climate, this view might seem naive. So is doing without weapons just wishful thinking? Do we need arms for peace?

Are eggs good for us? Are eggs bad for us? Official health advice sometimes to contradict itself. What food we consume is important for our health, so what should we actually eat?

Although no proof of the existence of extraterrestrial life has yet been found, the discovery of habitable planets in the universe makes it increasingly likely. But if aliens do exist, how should we make contact with them? And what would be the consequences of this unprecedented event in human history? Are we ready to meet the aliens?

The human body is home to some 30 billion microorganisms (bacteria, fungi, viruses, algae). The composition of this microbiome has a direct impact on us: the more diverse it is, the better our health. However, urbanisation, hygiene regulations and changing diets and lifestyles are leading to a loss of microbial biodiversity. So how can we bring back the microorganisms that have disappeared into modern life? And how important is it to us really?

While some people spend millions on holidays in space or splash out on extravagant weddings, others live in shanty towns and earn just a few dollars a day. Why do such inequalities exist in our world, despite a global economy that has produced the most wealth in human history?

Without water there would be no life on Earth. But what is so special about it? Research has shown water is much more than the tasteless liquid we drink almost without thinking, but rather a mysterious and unique substance present everywhere in our world. But could it be the key to life in the universe?

We humans think that we are the best creation on this earth. But with sickness, aging, brittle bones and weak muscles… are we actually badly designed? Would we benefit from bodily and cerebral upgrades? Will we all be cyborgs in the future?

It may seem that the idea of Truth is under siege. Donald Trump, for example, was elected despite countless false statements and lies and conspiracy theories are widely believed without the slightest bit of evidence to support them. Why is this? And can truth still be saved?

Once you become addicted to a substance you can live a life of abstinence, but you are never considered cured. Will this remain the case in the future, or can we use modern medicine to cure our addictions?

Setbacks and bad decision often leave a bitter taste in the mouth, but they can help you bounce back. Research shows that scientific and technical advances are often the result of trial and error and in psychology, it is accepted that failure makes us more resilient. So should we embrace failure more often to succeed in life?

We sometimes think of our ancestors in the stone age as primitive beings, unable to cope with complex tasks or the demands of our highly complex modern society. But were our ancestors from tens of thousands of years ago really less intelligent than us?

More than 1.3 million people die each year from infections with antibiotic-resistant bacteria. Are we facing another pandemic?

Hibernation in humans – so far, it's pure science fiction. However, some researchers suspect that humans might possess the genetic predisposition for hibernation. An artificially induced state of dormancy would save enormous resources and would also be of great interest for space travel. But could this be implemented in practice?

Success, failure, birthdays, funerals… any occasion can be an excuse to drink. However, the line between pleasure and addiction is very thin.

And, how can we protect ourselves from their influence?

For centuries, female sexuality was neglected and considered uninteresting by men. The apogee came in the 19th century, when doctors and pioneering psychiatrists concocted the wildest theories surrounding female pleasure.

The stock market is the temple of rationality, figures, data and models. But what happens when emotions drive prices? When panic takes over from analysis and heady euphoria pushes share prices through the roof? Is the world of finance actually ruled by human emotion?

Imagine for a moment that everything was reversed. It may sound mind-boggling, but it is not entirely absurd. Many of the molecules that make up life on Earth have a symmetrical counterpart—a mirror-image twin known as an enantiomer. These mirror molecules represent a promising avenue for the discovery of new and potentially more effective medicines. But what if we could go even further? What if it were possible not only to mirror individual vital molecules, but entire living organisms—bacteria, for example? What would happen if we managed to reverse life itself? And what would our world look like then?

Dominant, strong, a “real man.” Women want him, men want to be like him. This is the image of the “alpha male” portrayed by many masculinity influencers—some of them with millions of followers. Where does this idea of ​​the alpha come from? Is he truly the superior man, as nature intended? Or is it all nonsense?

To be remembered, to leave a legacy – that's what everyone wants. But what if, in 100,000 years, aliens visit the extinct Earth? What legacy would they find? Probably our trash. From the highest mountains to the oceans, from the atmosphere to our bloodstreams, it accumulates everywhere. Despite sorting and recycling, the question remains: Is trash our legacy?

Need a vacation? It's a sign that it's time to rest and relax. Yet, scientists can't explain what happens when we get away from it all, nor why and how vacations make us feel good. Given that they're such an integral part of our lives, how is it that their effects are so little understood?

Is our personality fixed from birth – or can we consciously change it? Can composure be learned, conscientiousness trained, and sociability increased?

Our feelings are something very intimate, something that belongs only to us—or at least we wish it did. But now, artificial intelligence (AI) can read our emotions and adapt to them. And if AI can handle our emotions so well, wouldn't it be easy for it to manipulate them? Or even control them?

When the subject of trauma arises, most people immediately think of extreme events: war, violence, severe accidents, or natural disasters. And indeed, such experiences can leave deep psychological scars. But what if trauma does not always manifest itself loudly? What else can give rise to trauma, and how can one even tell if one is affected?

Are UFOs being unfairly dismissed? For a long time, mysterious flying objects were associated mainly with science fiction and speculation. But scientists are now taking these phenomena more seriously and investigating what may actually be behind reports of unexplained sightings. Could UFO research lead to a completely new discovery? And how can science explain something that currently seems impossible to understand?

In reality, no state ever repays its debts. And yet, insolvency doesn't necessarily lead to bankruptcy. Public debt isn't just numbers; it also depends on growth, interest rates, policy, and, above all, confidence. When does debt become useful, and how can it become a threat?

A hotly debated topic: the impact of social media on young people. While Australia has already banned its use for those under 16, it's clear that likes, comments, and endless feeds bring both risks and opportunities.

We spend more than seven years of our lives working — a significant portion of our time on Earth. But as artificial intelligence increasingly takes over tasks once performed by humans, the role of traditional employment is being questioned. Could wage labor eventually be seen as only a brief phase in human history? Are we approaching the end of the work-based society and possibly one of the greatest transformations in human history?

Where did the antimatter go? According to our best theories, the Big Bang should have produced equal amounts of matter and antimatter, which would have annihilated each other. Yet matter exists and antimatter appears to be missing. Have we simply failed to detect it - or are our theories of the universe incomplete?

Are political parties to blame for everything? Trust in political parties is declining, and voters are increasingly looking elsewhere. This crisis is more than a political quarrel: it can threaten liberal democracy itself. So who is responsible - political parties, or voters themselves?
