Kurzgesagt Podcast: Science Revealed

You Need To Quit Weed

Cannabis is often labeled as harmless—but is it really? In this episode, we take a science-based look at marijuana use and explore when, why, and how it can start doing more harm than good. From brain chemistry and motivation to mental health, sleep, memory, and long-term dependence, we break down what research actually says about frequent weed use.  We discuss how cannabis affects dopamine, productivity, emotional regulation, and anxiety, why quitting can be harder than expected, and what withdrawal really feels like. This episode also examines who is most at risk, how tolerance quietly builds, and why “everyone’s doing it” isn’t a reliable measure of safety. This is not a moral lecture—it’s an honest conversation about health, habits, and making informed choices in a world where weed is increasingly normalized.

Thyroid Disorders and Clinical Management

Thyroid disorders affect millions of people worldwide, yet they often go undiagnosed or misunderstood. In this episode, we explore the science and clinical management of common thyroid conditions, including hypothyroidism, hyperthyroidism, Hashimoto’s disease, Graves’ disease, and thyroid nodules. We break down how the thyroid gland regulates metabolism, energy, growth, and hormone balance—and what happens when this system goes wrong. You’ll learn to recognize key symptoms, understand diagnostic tools such as blood tests and imaging, and gain insight into modern treatment options ranging from medication and lifestyle management to surgery and radioactive iodine therapy. This episode provides a clear, practical overview for anyone interested in endocrine health, medical science, or improving patient awareness and outcomes.

Stranger Things Physics Explained

What if the science behind Stranger Things isn’t as fictional as it seems? In this episode, we break down the real physics concepts hidden beneath the show’s supernatural storylines—from parallel universes and alternate dimensions to electromagnetism, energy fields, and the limits of human perception. How close is the Upside Down to real multiverse theories? Could portals, telekinesis, or time distortion ever exist according to modern physics? We separate cinematic fantasy from scientific fact, using real-world theories to explain what Stranger Things gets right, what it exaggerates, and what remains purely science fiction. Perfect for fans of the show and anyone curious about how pop culture intersects with real physics.
