    #3 - What’s Hiding at the Most Solitary Place on Earth? The Deep Sea

    S7:E14

    Sometimes the world feels boring. All the remote islands are visited, the arctic conquered, the dense jungles discovered. Except, there is still a place to explore: A wet deadly desert where mysterious creatures live in total darkness: The deep sea. Let us dive down.

    #4 - The Billion Ant Mega Colony and the Biggest War on Earth

    S7:E15

    In nearly every corner of the Earth, ants wage war against each other. Their weapons are what nature gave them. Some have strong armour, deadly stingers or sharp mandibles. And then there is this tiny, and not very impressive ant. But it rules the biggest empire any ant has ever built. A colony spanning continents and fighting wars that leave millions of casualties. Let’s take a look at this unlikely warrioress: Linepithema humile, the Argentine ant.

    #5 - What If We Nuke a City?

    S7:E16

    As you may have noticed, we like to blow stuff up on this channel. So when the International Red Cross approached us to collaborate on a video about nuclear weapons, we were more than excited. Until we did the research. It turned out we were a bit oblivious off the real impact of nuclear weapons in the real world, on a real city. And especially, how helpless even the most developed nations on earth would be if an attack occurred today. So hopefully this video demonstrates how extremely non fun a real world nuclear attack would be, without being to gruesome. This collaboration was a blast (no pun intended) and we want to say a huge thank you to the International Red Cross!

    #7 - This Is NOT An Anti Meat Video

    S13:E2

    Most of us love animals but also eat meat. Unfortunately, most animals we eat live in truly horrible conditions. We don’t torture them for better meat, just for cheaper meat. If we all paid just a bit more, we could avoid most animal suffering – often just for a few cents per meal. What would it truly cost us to avoid animal torture and still eat meat?

    #8 - Why Your Brain Blinds You For 2 Hours Every Day

    S13:E3

    Reality is not real. Your world is a prediction. Every sight, sound, and touch you experience is the result of calculations your brain makes before reality even reaches you. It fills in gaps, fabricates details, and even alters time itself so you feel like you’re in control. But if everything you know is an illusion… what does that say about you? What does it mean for your choices? Is there even free will?

    #9 - SOUTH KOREA IS OVER

    S13:E4

    South Korea is heading toward a demographic collapse unlike anything the world has seen before. With the lowest fertility rate ever recorded and a rapidly aging population, the country faces a future of economic decline, shrinking cities, cultural erosion, and a vanishing workforce. By 2060, nearly half of South Koreans could be over the age of 65, and entire regions may be abandoned as the population continues to shrink. How did South Korea reach this point? Why might it no longer be possible to reverse the trend? And what does this mean for other countries on a similar path?

    #12 - Why Does Fentanyl Feel So Good?

    S13:E7

    Fentanyl is the deadliest illegal drug in US history by far. It’s often described as the ultimate high, but it’s actually an inferior, short-lived, and brutally addictive version of heroin. In this video, we explore what opioids do to your brain and body, what it feels like to take them, and why so many people are dying from Fentanyl overdoses without ever choosing to take it.

    #13 - Why Is The US Dropping Billions Of Mutant Flies From The Sky?

    S13:E8

    A war has been raging for decades in the jungles of Panama, as we fight one of the most terrifying parasites on Earth. It is so relentless that our best defense is to drop 100 million radiation-blasted, flesh-eating flies from the sky – every week. It’s one of the most successful biological campaigns in history, but it’s a war we can never stop fighting… and one we can’t afford to lose.

    S13:E10

    No matter how likely your death is, there will always be a version of you that survives. At least according to one of the most bizarre interpretations of quantum mechanics, known as Quantum Immortality. Can science prove that you are unkillable? And does this mean our reality is split into an endless number of copies?

    Alcohol kills more people each year than wars, terrorism, homicides, and car accidents combined. It destroys bodies, relationships, and lives. Yet we toast with it at weddings, sip it at parties, and unwind with it after work. Why do we cling to something so harmful?

    S13:E13

    The ocean sunfish, or Mola, is one of the strangest animals alive. A massive, flat, derpy giant that eats jellyfish, drifts aimlessly, and carries parasites that even have smaller parasites of their own. Somehow, this awkward creature that feels like evolution’s inside joke doesn’t just survive in the world’s oceans… it thrives. But how? Like actually how?

    Some killer asteroids were found only days before flyby. If they had struck Earth, the power of thousands of nuclear bombs would have flattened cities and killed millions. What if we spotted a 100-meter asteroid just two weeks before collision? Can humanity be saved?

    #22 - Smoking is Awesome

    S12:E6

    We need to have an honest conversation about smoking: The problem with smoking is that it is way more than just a physical addiction. Smoking creates a temporary problem and offers an instant solution. Once your brain is used to nicotine, for up to 72 hours you are itchy,nervous and stressed – but one drag and instantly, you feel really good. It also helps you focus and take breaks during work, while suppressing your appetite. So why is it such a bad idea?

    #24 - Why You Are Lonely and How to Make Friends

    S10:E10

    Friends make life good. They provide the scaffolding that makes it not just bearable but fun. They give us a sense of meaning and purpose and are a source of security, self esteem and happiness. Almost nothing predicts how happy you will be as how connected you feel and a lack of social connection is associated with a number of diseases and a shorter life. But maybe you have scrolled through your phone, unsure who to call to go to a movie with, to celebrate with or ask for comfort. You may realize that you don’t have enough friends and feel lonely. And it is not just you. Disconnectedness and loneliness are widespread. Many people want more close friends but don’t know how to get them.
