  Do You Understand ISO? 20.08.2026 55мин

  ISO is one of the most important settings in photography and video—but it’s also one of the most misunderstood.In this episode, we break down what ISO actually does, how it affects the brightness and quality of your images, and why increasing ISO can introduce unwanted noise. We explore how ISO works alongside shutter speed and aperture to create the exposure you want.What does ISO really mean? When should you raise or lower it? Why can a brighter image sometimes look worse? And how can understanding ISO help you shoot better photos and videos?Whether you’re using a professional camera, a smartphone, or just getting started with photography, this episode makes ISO simple and practical.Because once you understand ISO, controlling light becomes a whole lot easier.  Hosted on Acast.

  Lab Grown Brains 15.08.2026 16мин

  What if scientists could grow tiny, simplified versions of human brains in a laboratory? In this episode, we explore brain organoids—three-dimensional clusters of human cells that can develop some features of brain tissue. These remarkable creations are helping researchers study how the brain develops, investigate neurological conditions, and explore potential treatments in ways that traditional laboratory models cannot always replicate. How are brain organoids made?What can they actually do?Could they ever develop something resembling consciousness?And what ethical questions arise when scientists create increasingly complex brain-like tissue? We explore the science behind organoids, their potential to transform neuroscience and medicine, and the fascinating questions they raise about what it means to create something that resembles part of the human brain. Because the closer science gets to understanding the brain, the more complicated the questions become.Become a supporter of this podcast: https://www.spreaker.com/podcast/kurzgesagt-podcast-science-revealed--6600013/support.

  Why Some Rainbows Turn White 30.07.2026 52мин

  Rainbows are usually known for their brilliant colors—but under certain conditions, they can appear almost completely white. In this episode, we explore the fascinating science behind fogbows, sometimes called white rainbows. These rare atmospheric phenomena form when sunlight interacts with extremely tiny water droplets in fog, creating a pale, ghostly arc instead of the vivid spectrum we normally expect. Why do the colors disappear? How are fogbows different from ordinary rainbows? And what other strange optical illusions can the atmosphere create? We explore the science of light, water droplets, and atmospheric conditions to uncover why one of nature’s most colorful spectacles can sometimes turn almost completely white. Because even when the colors disappear… the physics behind the rainbow is still extraordinary. 🌈Become a supporter of this podcast: https://www.spreaker.com/podcast/kurzgesagt-podcast-science-revealed--6600013/support.

  Is Perfect Prediction Possible 26.07.2026 45мин

  What if we could predict the future with absolute certainty? In this episode, we explore one of science and philosophy’s most fascinating questions: Is perfect prediction actually possible? From weather forecasting and artificial intelligence to quantum physics and chaos theory, we examine the limits of our ability to foresee what happens next. Can enough data make the future completely predictable? Why do even the most advanced computer models still make mistakes? And does the universe itself place fundamental limits on prediction? We dive into the science of probability, the butterfly effect, randomness, and the surprising ways small uncertainties can grow into massive differences over time. Along the way, we’ll discover why some events are remarkably predictable while others remain forever beyond our reach. Because the future isn’t just something we wait for—it may be something that’s impossible to know perfectly.Become a supporter of this podcast: https://www.spreaker.com/podcast/kurzgesagt-podcast-science-revealed--6600013/support.This episode includes AI-generated content.

  Why Alcohol is So Addictive 19.07.2026 27мин

  For many people, alcohol is part of celebrations and social gatherings. But for others, what starts as an occasional drink can gradually become a powerful dependence. In this episode, we explore the science behind alcohol addiction and why it can be so difficult to overcome. We examine how alcohol affects the brain’s reward system, alters decision-making, and changes the body’s chemistry over time, making some people more vulnerable to developing alcohol use disorder than others. Why does alcohol create cravings? Why can some people drink occasionally while others struggle to stop? And what happens inside the brain as dependence develops? Drawing on neuroscience, psychology, and medical research, we separate myths from facts and explain the biological, psychological, and social factors that contribute to alcohol addiction—as well as the pathways to prevention, treatment, and recovery. Because understanding addiction is the first step toward understanding the people it affects.Become a supporter of this podcast: https://www.spreaker.com/podcast/kurzgesagt-podcast-science-revealed--6600013/support.

  The 2026 Global Heat Crisis: Science, Impact, and Resilience 16.07.2026 49мин

  In mid-2026, extreme heatwaves and record-breaking temperatures devastated Western Europeand parts of North America, leading to more than 20,000 fatalities in June alone. Scientific analysis confirms that human-driven climate changesignificantly intensified these events, pushing temperatures several degrees higher than historical norms and fueling massive wildfires in France and Spain. The intense weather caused severe infrastructure disruptions, including the shutdown of a French nuclear reactor and the cancellation of major public celebrations. Experts advocate for nature-based solutions, such as urban tree planting, and sustainable cooling strategies to mitigate health risks as heatwaves become more frequent. While air conditioning remains a vital temporary tool, the sources emphasize that long-term safety depends on reducing greenhouse gas emissions and improving climate resilience. Local authorities across multiple continents issued public health alerts as these persistent heat domes shattered century-old records and impacted millions of people.Become a supporter of this podcast: https://www.spreaker.com/podcast/kurzgesagt-podcast-science-revealed--6600013/support.
