  • The sleep disorder you might not know you have - Alayna Vaughan

    Dig into the science of what causes snoring, and how chronic snoring can be a sign of sleep disorders such as sleep apnea.

    Uploaded 09-11-21

    --

    A leather mask that clamps the mouth shut. A cannonball sewn into a soldier’s uniform. A machine that delivers sudden electrical pulses. These were all treatments for a problem that has haunted humanity for millennia: snoring. It might seem harmless, but snoring can be a sign of something more dangerous. So, what exactly causes snoring? Alayna Vaughan digs into the troublesome sleep disorder.

    Lesson by Alayna Vaughan, directed by Rémi Cans, Boniato Studio.

  • The life cycle of a cup of coffee - A.J. Jacobs

    Trace the globe-spanning journey of coffee as it goes from plant to brew, and the complex infrastructure that makes it possible.

    Uploaded 04-01-21

    --

    How many people does it take to make a cup of coffee? For many of us, all it takes is a short walk and a quick pour. But this simple staple is the result of a globe-spanning process whose cost and complexity are far greater than you might imagine. AJ Jacobs traces the journey of this caffeinated elixir from seed to cup.

  • How do viruses jump from animals to humans? - Ben Longdon

    Discover the science of how viruses can jump from one species to another and the deadly epidemics that can result from these pathogens.

    Uploaded 08-08-19

    --

    At a Maryland country fair in 2017, farmers reported feverish hogs with inflamed eyes and running snouts. While farmers worried about the pigs, the department of health was concerned about a group of sick fairgoers. Soon, 40 of these attendees would be diagnosed with swine flu. How can pathogens from one species infect another, and what makes this jump so dangerous? Ben Longdon explains.

  • Can you solve the human cannonball riddle? - Alex Rosenthal

    Practice more problem-solving at https://brilliant.org/TedEd

    Uploaded 22-11-21

    --

    They call you the human cannonball. Your act involves flying through rings of fire, bouncing through a trampoline course, and catching the trapezist in the grand finale. Today’s pre-flight test fails dramatically, and upon inspection, your cannon has clearly been sabotaged. Unfortunately, it’s too late to abort the launch. Can you fix it in time to catch the trapezist? Alex Rosenthal shows how.

    Lesson by Alex Rosenthal, directed by Igor Coric, Artrake Studio.

    This riddle is adapted from a puzzle that appears in Boris A. Kordemsky's The Moscow Puzzles

    Diabetes has a history dating back to Ancient Greece. Our treatment of it, however, is more recent and was originally made possible with the help of man's best friend. Due to physiological traits shared with humans, dogs have saved countless lives through the discovery of insulin. Duncan C. Ferguson shares the story of the canine's great contribution to man -- and how we can all reap the medical benefits.
