Camouflage is nature’s ultimate game of hide-and-seek, and the secret to winning this game is all in the brain. By studying the masters of disguise, we can see how they trick the brain to make themselves invisible — and what this can teach us about how other animals see and perceive the world

You’re alive right now… at least I’m pretty sure you are. But you’re not TOTALLY alive. Bits of you are always breaking down, being thrown out, and being replaced. Even right now, parts of you are dying. Some of your cells even died before you were born. And some will never come back. These are all very strange, mildly uncomfortable things to think about. And what’s even stranger than that is a big fraction of your body is, was, and will never be alive. So how much of you is dead?

You’ve seen it in the comment section before: “Climate change is natural. It’s happened before and it will keep happening”. In reality, comments like these are the newest kind of climate change denial. In this video we’re going to learn about all the reasons that Earth’s climate changes, natural and otherwise, and then how we know that modern climate change can’t be blamed on natural forces. Maybe we can finally put this biggest myth about climate change in the trash.

Despite being one of the rarest letters in English, the letter X is everywhere. We sign letters with it, we rate movies with it, we name all sorts of things after it. We’re kind of obsessed with it. And that’s probably all thanks to math, where X stands for the unknown. Let's explore the bizarre history of how X took on this role…

Embarrassment. Awkwardness. Cringe. No matter what you call it. it’s one of the most unique human emotions, and one that’s particularly hard to figure out. But if a feeling exists and has lasted through evolution, then it probably has a purpose!

Who knew there was so much science in a bowl of cereal?
Don’t miss our next video! SUBSCRIBE! ►► http://bit.ly/iotbs_sub

Ever notice how cereal clumps up in your bowl, or how cereal sticks to the edges of the bowl? Bubbles in beverages do the same thing.You've probably seen this surface tension and buoyancy at work, but did you know there's some mind-blowing science behind it? What we learn in our cereal bowl even connects to the lives of tiny insects that walk on water.

Springtime means the arrival of green grass, bright flowers, and buzzing bees. But for many of us, it's also about sneezing, watery red eyes, and a runny nose, thanks to allergies. In this week's video, you'll learn why we get allergies, how our immune system turns against us to attack pollen and pets, and why allergies seem to be on the rise in developed nations.

Why is some science fiction so good at predicting actual science?

Don’t miss our next video! SUBSCRIBE! ►► http://bit.ly/iotbs_sub

Do Ray Bradbury, Arthur C. Clarke, Jules Verne, Philip K. Dick, Hugo Gernsback, Robert Heinlein, or Isaac Asimov hold a candle to H.G. Wells when it comes to correctly predicting the future of science via science fiction?

And why does some science fiction do such a good job of predicting the future in the first place?

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!

There’s been a lot of talk on YouTube lately about ocean plastic pollution and #TeamSeas. But there hasn’t been enough talk about the **ridiculously unthinkable scale of the ocean plastic pollution problem** or how it intersects with other environmental issues like climate change. And here’s a big spoiler alert: Nearly all environmental scientists agree that ocean plastic pollution isn’t a problem we can clean our way out of. So what CAN we do? That’s what this video is about.

Evolution has come up with some pretty amazing ways to get things done when it comes to animals, plants and microbes. From radiation-resistant bacteria (like Dr. Manhattan) to geckos who climb glass using atomic adhesion (like Spider-Man) to a shrimp that can shoot a bubble the temperature of the sun (like Aquaman), nature is pretty super!

The finest burritos in the world are made in San Francisco’s Mission District. But how can you get a hot & fresh one in New York City in time for lunch? Physics, that’s how. For this very serious and scientific video, we dug a classic documentary out of the vault that tells the story of the transcontinental burrito tunnel, and its successor, the transcontinental burrito hypertunnel. They are both true marvels of physics. Oh, and they aren’t real… but the science is.

A cosmic love story, starring a guy named Carl Sagan
Click here to SUBSCRIBE, it's FREE! -- http://bit.ly/iotbs_sub

Love is a complicated combination of brain chemicals and behavior that scientists are only just beginning to figure out. And it's remarkable that in every society that we have looked at on Earth, romantic love exists. So if love is so universal, and there are 7 billion other people out there looking for it, why can it seem like it's so hard to find?

In this episode, we'll look at what we can learn about the search for love from the search for extraterrestrial life. We'll start with Enrico Fermi's paradox of why we haven't been contacted by any extraterrestrials yet, and then at Frank Drake's equation to estimate the number of civilizations that might exist in our galaxy (updated with current numbers). Finally, we'll meet a young lady named Ann and see if we can calculate how many special someones there might be out there for her. It's a cosmic love story!

You may not be an expert, but perhaps you feel pretty confident that you could ride a motorcycle, or give someone a decent haircut - if you absolutely had to - right? Not so much, according to the psychological phenomenon known as the Dunning-Kruger Effect. Turns out we’re all at risk of being overconfident about something. Watch Joe put this theory to the test as he tries to land a 737 (in a simulator, of course). Oh, did we mention Joe's not a pilot?

A few years after the collapse of the Soviet Union, a top-secret, first-of-its-kind US spy satellite program was declassified, leading to the unexpected story of how former enemies became scientific allies, and technology invented for Cold War espionage was repurposed to study and combat the newest and greatest threat to human civilization: Climate Change.
