So how do you tell if someone is lying? Liars can use many tactics like changing up their tone of speaking, manipulating their facial expressions, being overly nice to you, etc. But how exactly do you know when you're being lied to? In this video, we have you covered. If you find yourself identifyin
Are you wondering how to spot a liar? Do you suspect that your friend is lying to you? It can be frustrating when our friends aren’t completely honest or upfront with us, especially about the things that matter, so sometimes we have to figure out for ourselves whether or not they’re telling the trut
A short introduction to nanotechnology, and why you should care about it. The video dives into materials science and advanced materials, and looks at how designing and engineering substances from the atoms they're made of upward allows novel properties to be developed and used. It also looks at res
View full lesson: http://ed.ted.com/lessons/the-language-of-lying-noah-zandan We hear anywhere from 10 to 200 lies a day. And although we’ve spent much of our history coming up with ways to detect these lies by tracking physiological changes in their tellers, these methods have proved unreliable. I
Are you feeling sad lately? What about depressed? Depression is a serious mental health disorder that needs professional help. One aspect of clinical depression is rumination or negative thoughts. This happens when we go into a spiral of talking negatively about ourselves. For example, "No body care
How safe is graphene when it’s used in face masks and other consumer and professional products? In this episode of Risk Bites, nanotechnology expert Professor Andrew Maynard looks at what’s known about the potential health risks associated with the engineered nanomaterial graphene, and how consume
What are the benefits and risks of using silver nanoparticles in consumer products, including colloidal silver? Risk Bites' Andrew Maynard looks at seven things you should know about this nanomaterial. Silver nano has been hitting the headlines for a few years now, both as a smart new technology fo
We'll be tackling the risks of nanoparticles and other particles more fully when Risk Bites launches formally in November. But until then, here's a roller-coaster ride of a video on what might be important when thinking about the risks and benefits or nanoparticles - or any other particles for that
What are advanced materials, and are they safe? In this second video in the Risk Bites series on advanced materials, we look at the emergence of increasingly advanced materials over the 20th century, and the development of multi-scale materials design and engineering, from the nanoscale to the macro
What make advanced materials potentially harmful? In part 5 of this Risk Bites series on advanced materials, we explore what characteristics of materials affect their safety, and increase their potential risks to human health. Risk Bites was created by Andrew Maynard. This week's video was prod
Carbon nanotubes, or CNT, are being used to make products stronger, lighter, faster, and more efficient. But are they safe? A growing body of research is raising concerns over the hazards presented by some forms of the material. As ever though, the risk to health depends on who is exposed to what
