Subscribe: http://bit.ly/iotbs_sub Twitter: @okaytobesmart ↓ More info and sources below ↓ 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.

Woo! But you don't have to call me "Doctor." Anyway, spring is in the air!! We're all thawing out from winter's chill, and for bees and flowers this season is about one thing: Feeding and fertilizing. Bees are amazing social insects, and their relationship with flowers is one of nature's coolest examples of "mutualism". It got me wondering: How do bees see the world? Enjoy this look at how bees see in ultraviolet and even sense electric fields!

It seems like every week someone tells us how the internet and the digital age are overloading our brains. Sure, sometimes it feels like we're being fed more information than we can handle, that we're paying attention to the wrong things. Are we giving our brain a fair shot? I explore some science that show how paying attention can be a bad thing, and then some science about how paying attention can be a very helpful thing Special cameos by Hank Green and Mike Rugnetta!

    Why is the Sky Whatever Color?

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!)
