The world of energy is a confusing place. What's better, nuclear or solar? What's the difference between fluorescent bulbs and LEDs? What's the difference between energy and power? And what the heck is a kilowatt-hour?!
In this video, we give you a tour of the essential principles behind the energy machine that puts fuel in our tanks and brings electricity to our homes. To be a good energy citizen, you need to speak the language

We know pollution is a problem on earth, but we’re filling space with our junk too. And if we don’t figure out a way to clean up space junk, we could end our interstellar dreams before they even get started. Today, we’re visiting some cool engineers in Switzerland to learn about the space junk problem and the giant space claw that might be the perfect solution.

If the human body could be distilled down into one molecule, what would our chemical formula be? And WHY is it that way? Is that one scene from Full Metal Alchemist even a little bit true?
There's a whole lot of elements on the periodic table, but life depends on relatively few of them in order to build all the things that keep us alive. This week, we'll look at why the chemistry of life is the way it is…

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 the sky blue? Or any color, for that matter?
Click here to SUBSCRIBE, it's FREE! -- http://bit.ly/iotbs_sub
It's a question that you'd think kids have been asking for thousands of years, but it might not be that old at all. The ancient Greek poet Homer never used a word for blue in The Odyssey or The Iliad, because blue is one of the last colors that cultures pick out a word for
In this episode, I'll tell you not only why the sky is blue, but why it's red at sunset. It turns out, those colors are all part of the same sunbeam. And when you're looking at a blue sky, you could be sharing a special moment with someone thousands of miles away. Next time a kid (or the kid inside you) wants to know why the sky is blue, you'll have science to back you up!
(We know that the Earth turns the wrong direction in the animation, sorry about that. Something weird happened when we were programming the animation and it got reversed. Or maybe time travel!)

When you stare up at the night sky, you might think that the universe is really black, but that's just because our eyes aren't sensitive enough to see the billions and billions of multicolored stars out there. Ever wonder why certain stars are certain colors? And what color is our sun, really? If we looked at enough stars, could we figure out the average color of the universe?

Ever not felt completely like yourself? There's a good reason for that. Because a large part of you . . . isn't you. Our bodies are home to ten times as many microbes as human cells. We are walking ecosystems, each of us home to thousands of different species on and inside of us. Meet your microbiome!
Sure, some bacteria are dangerous, but without our tiny friends we wouldn't be here (literally). Enjoy this introduction to your microbiome, and let me know in the comments if you'd like to know more about any part of your personal ecosystem!
