On top of a volcano in Indonesia, there are three lakes. But these three neighbors couldn't be more different, since each of them is a different vivid hue. Let's talk about the weird chemistry atop Keli Mutu Volcano and the three...

There's a few minerals that exhibit something called piezoelectricity and pyroelectricity, which mean that either heat or pressure can turn them electric. Here's a demo from the SciShow Rocks Box where you can see this for yourself - all...

Even if we find an earth-sized exoplanet, how can we be so sure that we're looking at earth 2.0? It might come down to how fast it's spinning.

Living on the moon won't be easy, but it might be worth taking a note from our ancestors, and setting up in caves

Montana sapphires come in a beautiful array of colors found in a few other places in the world. But geologists have no idea where they originated.

Computer models of climate change have long predicted that the ocean would turn green as a result of warming. But the change can't be seen by the human eye, so scientists weren't sure how they'd measure this effect... until it turned out...

The Sun is green, actually. We'll go into why the blackbody effect means the Sun emits more green visible light than any other color, and why evolution and color perception mean it's ok to see it as yellow, anyway.

Jewel beetles are pretty eye-catching with their glossy, bright coloration. But if you were a small creature that needed to avoid predators, you might think that eye-catching is the last thing you'd want to be. But it turns out that...

For most living things the color you see when you look at them is determined by pigments. But some of the most vivid colors we see in nature get their signature looks WITHOUT colorful molecules. How do these intense colors get their power?

We know that not everyone's vision is perfect, which is why some of us need glasses. But some people can also just see more stuff than others! From seeing UV and infrared light, to even having bonus color receptors in our eyes, there are...

You've seen those viral videos of colorblind people putting on special glasses and reacting to colors they've never seen before! Today, we'll explore how colorblindness works and what those glasses try to do to fix it! Hosted by: Hank Green

Lots of life on Earth can fluoresce, creating a beautiful neon world of camouflage, communication, and adaptation that is hidden from the human eye.

When you see a black cat, you might think of witches and goth bands, but they're also a great example of a melanistic animal, and they're not the only ones!

From the ability to see “invisible” types of light to the power to taste all over their body, meet five incredible animals whose super senses far surpass our own! Hosted by: Michael Aranda
