    How can sand, blown by the wind, form such intricate and beautiful patterns as ripples and dunes? The answer is a surprising secret of self-organization. In this video, we travel to Great Sand Dunes National Park in Colorado to climb the largest sand dunes in North America and bring you the science of how wind and sand combine to create ordered landforms out of chaos. The science must flow.

  • Sonic Hedgehog Gene - Why You Have Thumbs Rather Than Fins

    Ever wonder why you have thumbs?
    Don’t miss our next video! SUBSCRIBE! ►► http://bit.ly/iotbs_sub
    The human hand, with its multi-talented thumb, might be man's greatest tool. But did you know we can trace that thumb, and the hand and arm it's connected to, all the way back to a 375 million-year-old fish named Tiktaalik?
    This week I sit down with paleontologist and geneticist Dr. Neil Shubin to learn what a fish, and a little blue hedgehog, can teach us about the evolution of thumbs.
    Be sure to watch Neil Shubin's special 3-part series "Your Inner Fish" on your local PBS station, premiering Wednesday, April 9 at 10 PM Eastern!

  • This Is Where New Ideas ACTUALLY Arise

    The idea of the lone genius creating everything isn’t just misleading. It’s harmful and wrong. Innovation thrives when people work together, and rather than nice linear paths, new ideas come from chance events and unexpected connections.

    Waste not, want not… right? Poop, in all of its various forms throughout nature, shapes the world in ways you might not imagine. One creature’s waste is another’s fuel, and all over nature these leftovers help new life spring up. Here’s how whales, birds, worms, bats, and more help the world breathe clean, thanks to their poop.

    This video was supported by Bill and Melinda Gates. You can check out the Gates Annual Letter here: http://b-gat.es/2lhhtmJ.
    ↓ More info and sources below ↓
    We’re proud to collaborate with Bill and Melinda Gates for this week’s video! It may sometimes seem like things are getting worse, but there’s lots of reasons to be optimistic about the future. More people have access to toilets and sanitation than ever before. Thanks to public health improvements like this, since 1990, 122 million children’s lives have been saved. Diseases like polio are nearing eradication. Women have more access to health care and education than ever before.
    But our work is not done. How can YOU help make the future better for the world’s poorest?
    SPECIAL THANKS:

    During the 2017 Project For Awesome livestream, I promised I’d make a tuatara video if we hit our fundraising goal, and I’m a man of my word! Little did I know I’d get to meet a tuatara and learn things about a 200 million year old branch of life that would blow my mind. Get ready to meet the chillest reptile, weird living fossil, and star of Turtles All The Way Down… the tuatara.
