    The 40 or so muscles in the human face can be activated in different combinations to create thousands of expressions. But do these expressions look the same and communicate the same meaning around the world regardless of culture? Is one person’s smile another’s grimace? Sophie Zadeh investigates.

    Lesson by Sophie Zadeh, animated by Estúdio Bacuri.

  • Your brain is more than a chemical bag - David Anderson

    View full lesson: http://ed.ted.com/lessons/your-brain-is-more-than-a-bag-of-chemicals-david-anderson

    Modern psychiatric drugs treat the chemistry of the whole brain, but neurobiologist David Anderson believes in a more nuanced view of how the brain functions. He illuminates new research that could lead to targeted psychiatric medications -- that work better and avoid side effects. How's he doing it? For a start, by making a bunch of fruit flies angry. (Filmed at TEDxCaltech.)

  • How will AI impact the world?

    Explore the current limitations of artificial intelligence and the possibility of creating human-compatible technology.

    --

    In the coming years, artificial intelligence is probably going to change your life— and likely the entire world. But people have a hard time agreeing on exactly how AI will affect our society. Can we build AI systems that help us fix the world? Or are we doomed to a robotic takeover? Explore the limitations of artificial intelligence and the possibility of creating human-compatible technology.

    This video is based on interview excerpts from the Radio Davos Podcast. The episode is called, “The promises and perils of AI - Stuart Russell on Radio Davos”.

  • What's worse than a wasp's sting? Slaughter - Miles Zhang

    Explore the gruesome evolutionary strategy employed by parasitoid wasps where they feed off other animals to grow their offspring.

    --

    A cockroach and jewel wasp are locked in battle. The wasp latches onto the cockroach and inserts her stinger into the cockroach's brain, where her venom blocks its fight-or-flight response. Now, the cockroach is essentially a zombie, and its carcass will be used to grow the wasp’s offspring. Miles Zhang explores the gruesome evolutionary strategy known as parasitoidism.

    Lesson by Miles Zhang, directed by Denys Spolitak.

  • Kabuki: The people's dramatic art - Amanda Mattes

    View full lesson: http://ed.ted.com/lessons/kabuki-the-people-s-dramatic-art-amanda-mattes

    Uploaded 30-09-13

    The Japanese dance and theater art of kabuki, derived from the word kabuku, meaning "out of the ordinary," can be traced back to the streets of seventeenth-century Kyoto. Kabuki became a dramatic art for the common people, with its use of makeup and facial expressions rather than masks, as well as a playful take on current events. Amanda Mattes tracks the evolution of kabuki and its place in Japan's rich cultural heritage.

    Lesson by Amanda Mattes, animation by Tom Gran.

    After drinking a few glasses of water on a hot day, you might be struck with a sudden ... urge. Behind that feeling are two bean-shaped organs that work as fine-tuned internal sensors.

  • Are Elvish, Klingon, Dothraki and Na'vi real languages? - John McWhorter

    View full lesson: http://ed.ted.com/lessons/are-elvish-klingon-dothraki-and-na-vi-real-languages-john-mcwhorter

    Uploaded 26-09-13

    What do Game of Thrones' Dothraki, Avatar's Na'vi, Star Trek's Klingon and LOTR's Elvish have in common? They are all fantasy constructed languages, or conlangs. Conlangs have all the delicious complexities of real languages: a high volume of words, grammar rules, and room for messiness and evolution. John McWhorter explains why these invented languages captivate fans long past the rolling credits.

    Uploaded 21-04-14

    Atmospheric scientist Karen Kosiba studies how tornadoes form and do damage. Getting measurements near the surface of these twisters is difficult, though, and driving into them is a practice mostly reserved for the big screen. In this TEDYouth Talk, Kosiba describes how she and her team use observations and modeling to track these super storms, while sharing some incredible footage from the field.
