Stars have cores hot and dense enough to force atomic nuclei together, forming larger, heavier nuclei in a process known as fusion. In this process, the mass of the end products is slightly less than the mass of the initial atoms. But that “lost” mass doesn’t disappear — it’s converted to energy … a lot […]
Each year, approximately 20 million people receive a cancer diagnosis. During this time, patients are introduced to the concept of cancer staging, a system that typically assigns a number from one to four to describe the extent of their cancer. But what do these numbers mean? Understanding the stage of cancer can be confusing. TED-Ed’s […]
Researchers have created a smiling robot face made from living human skin cells, promising a future where robots can emote and communicate in a more lifelike way. This breakthrough not only enhances robotic interaction but could also revolutionize the cosmetics industry with its realistic wrinkles. The skin is a cultured mix of human cells in […]

A rather old but very informative video explaining why we have blind spots and a technique to help you see the blood vessels inside your own eyes! [Guillaume Riesen]
Think you have free will? This mind-bending video explores the possibility that your choices are just an illusion. Your body is made up of particles that blindly follow the laws of physics, with every outcome already predetermined. Could it be that you don’t have any free will at all? Dive into the debate: Is free […]
Typically, with any piece of technology, you pump one unit of energy in and you get about one out. That’s just the first law of thermodynamics: energy has to be conserved. But there’s a piece of technology called a heat pump, where for every bit of energy you put in, you get three to five […]
