Laughing is a universal human behavior, one that transcends borders of language and culture. But it's also REALLY WEIRD. Why do we do it? The answer has less to do with humor than you might think

I’ve explained a lot of weird bodily functions on this show but there’s one that we haven’t covered that’s always confused me: Tickling. What are you for, tickling? What’s the point of you? Why do you exist? Why do you make us laugh even though we hate you? Let’s dig into our evolutionary past to try and find an answer.

Our lizard friend the Gila monster probably has no idea that a chemical in its spit inspired one of the most important medical advancements of the 21st century. But this story is really about something bigger. Something deeper, beneath the surface. About why we do science in the first place. And about what kind of questions are the best ones for scientists to ask.

Dorothy went over one. LeVar Burton read to us under one. In a song, Kermit the Frog connected us to one. Even Mork's suspenders were made of them.
Our culture, and our skies, are full of rainbows, but do you know how they form? Do we all see the same rainbow? Could cyborg-enhanced mantis shrimp eyes someday see a bigger rainbow?
The answer to all these questions involves a little physics, and the number 42.

It never gets dark anymore. Not REALLY dark, anyway. Not like it used to. Light pollution is not only making it more difficult to see the night sky, but it's also affecting our health. For the past century and a half, since the dawn of electric light, we’ve been losing our connection to the night. We need artificial light for modern society, of course. The problem is, we need darkness for our health, and for the health of wildlife and ecosystems, and we’re not getting enough of it. I traveled to McDonald Observatory in far west Texas, one of the darkest places in North America, to learn what people are doing in order to preserve dark skies, and to see truly dark skies for myself (and so I could show them to you!). This video features time lapse night sky images that I’ve been collecting for the past few years, and I hope they make you feel something special. Turn out the lights, keep looking up, and don’t be afraid of the dark.

For centuries, diamonds were one of the most mysterious materials on Earth. They were beautiful, indestructible, and completely unexplained. Today, we’re exploring how scientists unlocked their secrets, and how one lab recreates the extreme conditions in Earth's mantle to make diamonds… out of dead people.

If bees go, will they take us with them?

↓ More info and sources below ↓
Bees, wild and domesticated, are in big trouble. Bee colonies are dying off at alarming rates, and the cause isn't clear. Pesticides, habitat loss, disease… there's a laundry list of likely culprits. We rely on these tiny pollinators for a majority of our fruits, veggies, and nuts… if they disappear, could we be next?

How do we protect what we don’t know exists?
Don’t miss the next video! SUBSCRIBE! ►► http://bit.ly/iotbs_sub
↓ More info and sources below ↓
How many species are there on Earth? In biology, this is one of a fundamental question that we still don’t have a very good answer for. Imagine if chemists didn’t know all the elements of the periodic table, or if physicists didn’t know all of the particles of the standard model. Knowing how many different species there are is information we need to know in order to protect the environment, but it’s a lot harder than you think!
Check out last week’s video, where we find a weird caterpillar in the Peruvian Amazon and ask “How do you discover a new species?”

Half a century ago, astronauts got on top of a really big rocket and sent a tiny little capsule on a 384,000 km trip to the moon and back. And they were able to do it because a lot of extremely smart and dedicated people pushed engineering and chemistry to the limits in order to create a 36-story tower of carefully-controlled space fire powerful enough to escape Earth’s gravity. I went to NASA in Houston to talk to astronaut Don Pettit about how they did it, and if we’ll be able to do it again.
Special thanks to Don Pettit and NASA
