Why Scientists Are Puzzled By This Virus You’ve got trillions of viruses inside you – right now! But these aren’t the viruses you fear. Some of them are your body’s secret protectors, keeping deadly bacteria in check and even killing cancer cells. But what happens when they turn against you? Let's look at the wild world of the human virome. @Kurzgesagt_InaNutshell

We Need to Rethink Exercise (Updated Version) After hearing your feedback on our initial video, we consulted experts, revised the script, and added more information to the parts that were too simplified. All changes and the link to original video (now unlisted) are listed in the infobox for full transparency. This experience was uncomfortable, but ultimately encouraging for us. It reminded us that it is a challenge to make ten-minute videos on complex topics without cutting too much and that we need to be constantly aware of this. @Kurzgesagt_InaNutshell

We Traveled Back in Time. Now Physicists Are Angry Time travel is possible. In fact, you’ve been doing it since the day you were born. But what if we told you there’s a way to hack the universe and manipulate time itself? We just have to do two simple things to make it happen: 1. Make a lot of physicists grumpy. 2. Shoot one twin through space against their will, while the other chills on Earth. Let's go! @Kurzgesagt_InaNutshell

Fever Feels Horrible, but is Actually Awesome! Fever feels bad. So we take medication to suppress it – but is this a good idea? It turns out fever is one of the oldest defenses against disease. What exactly is a fever, and how does it make your immune defense stronger? Should you take a pill to combat it? @Kurzgesagt_InaNutshell

A.I. ‐ Humanity's Final Invention? Humans rule Earth without competition. But we are about to create something that may change that: our last invention, the most powerful tool, weapon, or maybe even entity: Artificial Super intelligence. This sounds like science fiction, so let’s start at the beginning. @Kurzgesagt_InaNutshell

We Need to Rethink Exercise – The Workout Paradox Exercising doesn’t help you lose weight. In fact, it barely changes your daily calorie burn. Welcome to the workout paradox! Let’s dive into the science of how your body actually handles calories and sabotages your best efforts to burn them. @Kurzgesagt_InaNutshell

This Disease is Deadlier Than The Plague The white death has haunted humanity like no other disease following us for thousands, maybe millions of years. In the last 200 years it killed a billion people – way more than all wars and natural disasters combined. Even today it’s the infectious disease with the highest kill count. But what is this horrible disease? @Kurzgesagt_InaNutshell

Are You an NPC? You may think you have free will and can choose what you do, but this might be an illusion. Your body is made up of particles that blindly follow the laws of physics, with every outcome already predetermined. So, you might not have any free will at all. Is free will an illusion, or does it exist? Which philosophical camp is right? @Kurzgesagt_InaNutshell

Smoking is Awesome 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? @Kurzgesagt_InaNutshell
