Ever wondered how fireworks work? With chemical compounds, that’s how! Let’s look into why they glow in different colors.
I love the color blue! It’s not found as often naturally as I’d like. Someone’s probably written a doctoral thesis on the topic, but it seems that evolution favors other colors.
Our world is full of beautiful colors, so it’s easy to forget that the spectrum of light visible to humans is a teeny sliver of what’s out there in the universe. But wouldn’t it be fantastic to see in the dark? Scientists have done that, with mice!
I’ve heard people ask, ‘would you rather fly or be invisible?’ I think both! But invisibility may be closer than we think! Researchers are working on exactly that. They’ve had success on a small scale.
