Why can't laptop screens be viewed outside like e-readers can? It turns out, they use very different technology. But engineers are working on closing the gap.

We know that glass is fragile - that's like, it's main thing. But research is working on improving how we make glass to make it unbreakable, or at least as close as we can get. Here's the latest on how to make truly shatterproof glass!

Thomas Edison often gets credit for the invention of the light bulb, but a good argument can be made that they were around centuries earlier in the form of barometric light. <br/>

A poet once said, "The whole universe is in a glass of wine." We will probably never know in what sense he said that, for poets do not write to be understood. But it is true that if we look in glass of wine closely enough we see the...

Glass is made of sand, which is a kind of rock. But glass is transparent, and rocks aren’t transparent. What’s up with that? Why is glass clear? And why can I sit on a chair? And why can we touch anything? Today we zoom down to the weird...

Sponges might not look like particularly complex animals, but they've had billions of years to evolve their own special systems. And one of those systems might involve sending messages through their body in the form of light.

If you’ve managed to break your boxy old computer monitor by sticking a magnet on it, you have a lot to learn about the 20th century technology of cathode ray tubes.

We've collected all the episodes we've done over the years answering questions about water. Pour yourself a glass before diving into this watery compilation!

People ask Google everything under the sun. One of the most commonly searched questions in the world is “How much water should I drink a day?” SciShow has the answer!

What is heavy water, and is it safe to drink? Heavy water, or deuterium oxide, has some pretty important scientific applications. But what would happen to your body if you actually drank it? Hosted by Hank Green.

We usually think of 'hacking' as a bad thing, but scientists are working on ways to hack the brain that will greatly benefit people with prosthetics, and maybe someday people with paralysis.

There are 118 elements on the periodic table, but it seems like only a handful of them get any attention. But just because you haven't heard of an element doesn't mean that it isn't a vital part of everyday life! Learn about these lesser...

Today's data storage solutions have an expiration date. What's on the horizon to replace them?

Some might call sand coarse, rough and irritating, but there’s no denying that it’s used everywhere: from glass to asphalt, sand is a key ingredient for all sorts of materials in construction and technology. But this heavy reliance on...

Water is one of the most abundant and important substances on Earth, so you think we'd know everything there is to know about it. Turns out, water is so much stranger and more complex than we ever thought! Join Olivia Gordon for a new...

Long before we had cameras scientists still needed visual documentation—enter the science illustrator!
