Fluorescence isn't just a cool effect that turns your white T-shirt neon purple under a black light. Its discovery opened our eyes to a whole new field of science and engineering. And it's all thanks to a crystal called fluorite....

How Modern Light Bulbs Work

Fireflies, crustaceans, jellyfish -- lots of living things glow, and they do it for all kinds of reasons, some of which we haven’t even discovered yet.

If you're lucky enough to find a glowing rock, it likely doesn't mean you're the chosen one. In fact, it could have to do with one of these five phenomena! Learn about the quantum mechanics of glowing rocks in this new SciShow Episode...

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

The most advanced robots in the world might not be exactly what you’re expecting. But they’re shaping humanity’s future. Hosted by: Michael Aranda

Of all the weird animals that exist in the world, platypuses are up there with the weirdest, and last year scientists discovered something even more peculiar about their fur: it glows! What may be even more strange, though, is how little...

In 2009, a satellite circled Earth, scanning and sorting the wavelengths reflecting off the planet's surface. Researchers noticed something baffling: an unexpected wavelength of unknown origin. They tried looking at Earth with only this...

Today Hank and Sam figure out if medical side effects could help you "do crimes" and whether you can have a "gentle hate."

Fluorescent molecules are useful for a lot more than just making you look cool at your local rave. Fluorescence turns out to be a kind of chemical superpower that lets us tackle all kinds of problems, from solving crimes to saving lives!

If you find a glowing rock, it probably doesn't mean you're the chosen one. If it's one of these five phenomena, it's quantum mechanics, not narrative significance.

Talk Show: Henry Reich, Fluorescence, and a Half-moon Conure

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

Fabric brighteners can liven up your old, faded clothing. But they don’t actually clean your clothes, and they’re often banned in the military!

Howcast - If you have a stone that you're not sure is the real thing, try these methods to find out for sure.

Compact fluorescent light bulbs, or CFLs, use about 75% less energy, give off 90% less heat, and last up to ten times longer than old-fashioned incandescents. Changing over is as easy as... well, screwing in a light bulb.

This video discusses the restoration of Michelangelo's Rondanini Pieta using a new technique called fluorescence lifetime imaging. The technique allows restorers to accurately identify and remove dirt and unwanted materials from the...

Finding scorpions in the desert at night is surprisingly easy with an ultraviolet torch since scorpions fluoresce under UV light. This phenomenon, where scorpions absorb UV light and re-radiate it as bright neon green, isn't unique to...
