Did you know we can actually make diamonds in a lab? It's true! We can! And this is both really good and really cool. In this episode of Crash Course Kids, Sabrina shows us how materials scientists have done just that and why it's so...

It may sound like the stuff of sci-fi movies, but diverting food waste from the landfill and converting it into electricity has become a real thing. William Brangham visited Ben & Jerry’s Vermont ice cream factory and the operations next...

Today, a lot of us walk about in leather, cotton, or other boring fabrics. But researchers are working to make the future way cooler, with flame retardant seaweed fabrics, self-healing sea silk, and polar bear inspired de-icing...

Magnetic Levitation

How do magnets work? Why do they attract and repel at long distances? Is it magic? No... it's quantum mechanics, and a bit more, as we explain in this, the longest MinutePhysics video ever.

Magnets are amazingly strong... but there's a very easy way to destroy them. All you need to know is a little bit about ferromagnetism, paramagnetism, and temperature!

Magnets - how DO they work? We've got the answer for you, plus a bunch of weird fun magnet facts - where they got their names, why hitting some stuff with a hammer can turn it into magnets, and even why we feed magnets to cows, on purpose.

This month's Rocks Box is pyrite, also called fool's gold. But this fool's gold might not be so foolish, since we can use it to get all kinds of other minerals we really need, and it may be a key to getting real gold after all.

The ability to produce synthetic spider silk would give us bulletproof vests better than Kevlar, biocompatible sutures and wound dressings, and even space elevators. The problem is being able to make it in large amounts. One group may...

Jessi and Squeaks enjoy the winter season by constructing a model of the Fort out of gingerbread!<br/>

If you've ever looked at the bottom of a disposable bottle or cup, you've probably noticed a recycling symbol. Seeing this, many people assume the item should be put in a recycling bin. Yet many plastics are incapable of being recycled...

The Moon is pretty prime real estate once you get past the lack of oxygen, resources, and general mobility, but if quality of life isn't what you're after, here's how we might make it all work.

Earth didn't always have the land beneath your feet, but what might have caused it to form is a bit of a mystery.

Astrophysicists have discovered a black hole that for millions of years has been blasting vast particle beams in opposite directions across the sky. And has recently swiveled to point its one of these jets directly at us. Is this an...

We already have the technology to bring humans safely to Mars and set up small settlements - or at least could do within a generation. But those settlements will need to be cocooned - shielded against the deadly cold, intense radiation,...

How is it possible to have cataclysmic eruptions without any real cataclysm?

In some places, the rocks below the Great Unconformity are about 1.2 billion years older than those above it. This missing chapter in Earth’s history might be linked to a fracturing supercontinent, out-of-control glaciers, and maybe the...

What if we could use waste to create resilient and sustainable buildings? Bringing out the beauty of the dirt beneath our feet, climate-responsive architect Vinu Daniel shares how he and his team are giving local and discarded materials...

Humans may use fiber optic technology to make everything from novelty desk toys to high speed internet cables, but Nature has its own ideas. For decades, scientists have debated to what extent polar bears may use the optical properties...

One of the toughest materials known to science is made not by humans, but by nature... and it's inside of oysters.

Luckily, we live in a time where we don't have to worry about smallpox anymore. It's a horrible disease, but through smart vaccination techniques, we took it from killing millions worldwide, to being eradicated from the planet!

During long, cold winters in medieval Europe, church organs grew gray, sickly-looking circles that spread over their pipes. People back then believed that this was the work of the devil, but as it turns out, it’s just some pretty simple...
