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?

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.

Scientists overwhelmingly agree that our climate is changing, Earth is getting warmer, sea levels are rising, and it's primarily because of humans putting lots of carbon dioxide in the atmosphere. Yet 4 in 10 Americans aren't convinced. Here's what psychologists and sociologists have to say about why some people don't believe in climate science.

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?

Why do we love people we're related to? Compared to strangers, why do we feel such a deep sense of connection with our family members? Sure, they're nice to us, we take care of each other, and we often live with them, but there has to be a deeper biological reason. That reason, unsurprisingly is evolution. In this video, I explain why taking care of our family, or even dying for them, makes sense in the eyes of evolution.

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!

“In Our Nature” is a NEW special limited series on It’s Okay To Be Smart!
We’re on PATREON! Join the community ►► https://www.patreon.com/itsokaytobesmart
↓↓↓ More info and sources below ↓↓↓
Seemingly distant ecosystems, even half a world apart, are connected in surprising ways. In this special limited series, Emily Graslie and Trace Dominguez join me as we explore the universal rules of life that tie together Earth’s living systems. In episode 2, we study the complex family relationships of elephants in Africa’s Serengeti plains and how their shared knowledge can help them survive. Then we travel to San Francisco to discover how the intricate songs of birds have changed in the face of our own culture. How common is culture in the animal kingdom? And what role does it play in the survival of species?

00:45 What is culture?
02:42 Do animals have culture?

Seemingly distant ecosystems, even half a world apart, are connected in surprising ways. In this special limited series, Emily Graslie and Trace Dominguez join me as we explore the universal rules of life that tie together Earth’s living systems. In episode 3, we look at ecosystems at their largest and smallest scales of time and size from the Serengeti to Andrews Experimental Forestin Oregon. How does the cycling of nutrients and molecules make life possible on Earth? Who are these recyclers and scavengers? Sometimes this recycling happens fast and violently, and sometimes it happens slow and beautifully.
In Our Nature is a special miniseries produced by It’s Okay To Be Smart for PBS. Stay tuned for more episodes coming this summer, here on our YouTube channel!

It’s one of the most annoying sensations our bodies can feel, but does anything feel better than when you scratch an itch? Ok, maybe *some* things. But itching and scratching are up there. How does this weird sensation work? And what is itching for?

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.
