Why do we sleep? We spend a third of our lives in slumber, but science has yet to determine exactly why we have do it. Here’s a look at how sleep works, why we’re not getting enough sleep, what happens if you DON’T sleep, and an idea about where sleep came from in the first place.

Most people are taught that dinosaurs went extinct 66 million years ago when a giant meteor crashed into the Yucatan peninsula. I'm here to tell you that's wrong. Dinosaurs are alive and well today, and you don't have to go to Jurassic World to see them (although hanging out with Chris Pratt would be cool)
We have living dinosaurs all around us. We just call them "birds". Yes. Birds are dinosaurs.

Part 2 of our special series on Human Ancestry. Watch it all: http://bit.ly/OKTBSHuman
↓↓↓More info and sources below ↓↓↓
In part 2 of our special series on human ancestry, we ask why we are the only surviving branch on the human evolutionary tree. Just 50,000-100,000 years ago, Earth was home to three or four separate human species, including our most famous cousins: the Neanderthals. New research has shown that Neanderthals were not the brutish, unintelligent cavemen that cartoons make them out to be. They were creative, smart, social, and perhaps even had complex language. So why did they go extinct as soon as Homo sapiens moved into their territory? Does any trace of them live on today? Why don’t we have Neanderthal neighbors?

You've felt cold before. Sometimes it's cold outside. But what if I told you that "cold" isn't real? There's no substance or quantity called "cold" in science. We can't measure the amount of "cold" in something. Instead it's about what's NOT there. In this week's video, learn the difference between heat and temperature, why a wind makes us feel colder, and what it's like to live as a mass of jiggling atoms. This is the physics of cold

So maybe we can't outrun cheetahs or antelope, but humans are uniquely adapted for long distance running. What does science have to say about marathon running? To find out, (and because I was feeling a little crazy) I decided to run one!

This is part 3 of our special series on Human Ancestry!
Watch the entire series here ►► http://bit.ly/OKTBSHuman
↓↓↓More info and sources below ↓↓↓
In part 3 of our special series on human ancestry, we investigate how closely related we all really are. Basic math tells us that all humans share ancestors. But you’ll be amazed at how recently those shared ancestors lived. Thanks to genetic data in the 21st century, we’re even discovering that we really are all descended from one mother.

Glass is made of sand, which is a kind of rock. But glass is transparent, and rocks aren’t transparent. What’s up with that? Why is glass clear? And why can I sit on a chair? And why can we touch anything? Today we zoom down to the weird world of electron clouds and quantum touching to find the answers.

From spirals to spots to fractals, nature is full of interesting patterns. Many of these patterns even resemble geometric shapes. One of the most common? Hexagons. Why do we see this six-sided shape occur so many times in nature? This week we explore why hexagons are so common in the natural world, from honeycomb to bubbles to rocks, and what their mathematics, physics, and biology may have in common.

How do you make a Grand Canyon?
Thanks to Mike from PBS Idea Channel and Jamin from PBS Game/Show for hanging out at the Grand Canyon with me!

Special thanks to Raymond Schillinger for great camera work!
I was in Arizona recently for Phoenix Comic-Con, and had the amazing pleasure of seeing one of Earth's greatest natural wonders… the Grand Canyon. More than a mile deep, and several miles across, it just defies belief. But I couldn't help but think, the Colorado River down at the bottom isn't that big. How did it cut a canyon so massive? How old is the Grand Canyon?
Here's its story

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.
Thanks to the following for their expert info:
