Scientists have been slowly extending the periodic table one element at a time, pushing to higher and higher masses, and have discovered some incredibly useful materials along the way. But the elements at the current end of the table are...

Life’s been around on Earth for at least 3.7 billion years. But for most of that time, it was incredibly boring — just simple little cells squirming around in water. It only got interesting in the last few hundred million years. And that...

It's been said that your body contains billions of atoms from every famous person who ever lived. But is that true? And how do we know? Hosted by: Savannah Geary (they/them)

There's a town in northern Mexico called Ojuela that's got a rich history of valuable mining industry, but nowadays is largely deserted. But it's getting a new, second life thanks to a type of mineral forming process fittingly called...

The most common substance in the world is literally IN the world. It's a mineral called bridgmanite, and it belongs to a class of minerals (called perovskites) that scientists are trying to use in the next generation of solar panels....

If you look at a copy of the periodic table, you might notice that basically every element after lead is labelled as radioactive. And the vast majority of those elements wind up decaying into some version of lead eventually. But why is...

Unlike Earth, our Sun is a giant ball of mostly hydrogen and helium. Astronomers managed to figure that one out roughly 100 years ago. But after all this time, they still can't come to an agreement on what "mostly" means, precisely.

January babies, rejoice! This month's SciShow Rocks Box video is the story of garnets, and how these fabulous gemstones help us solve geological mysteries, from the Italian Alps to the Himalayas.

About 99.9% of your typical human body is made of just 11 elements from the periodic table. But hiding in that remaining 0.1% are some elements that do some very important jobs to keep you alive and healthy. Including some elements you...

One of the most famous elements in the periodic table doesn't really belong anywhere chemists would like to put it.

Supernovae are only rare to the passive stargazer, but if you’re an astronomer studying them, you get to see some of the most brilliant explosions in the universe. Here are five of the most significant supernovae known to science.

We all want green energy to stop climate change, and one option is hydrogen. But achieving green hydrogen is tough, so some want to consider so-called blue hydrogen instead. Support for this video provided by Gates Ventures.

Einstein once asked whether “the moon exists only when I look at it?". It was rhetorical objection to the idea that measurement in quantum mechanics causes reality to become real. But there was a time when the moon didn’t exist, and then...

Adamantium, bolognium, dilithium. Element Zero, Kryptonite. Mythril, Netherite, Orichalcum, Unobtanium. We love the idea of fictional elements with miraculous properties that science has yet to discover. But is it really possible that...

Pin-pricks in the celestial sphere, through which shines the light of heaven? Or gods and heroes looking down from their constellations? Or lights kindled above middle earth by Varda Elbereth and brightened with the dew of the trees of...

Throughout history, there has been much speculation about what the fate of the universe would be. Many theorized that the universe would eventually succumb to the pull of gravity, and reverse its expansion in what was being called ‘The...

In astronomy we study things that are very far away. It’s a powerful challenge because even the brightest objects are almost impossibly faint when you view them from the other side of the universe. But there’s an up side. If the light...

Carl Sagan’s famous words: “We are star stuff” refers to a mind-blowing idea – that most atomic nuclei in our bodies were created in the nuclear furnace and the explosive deaths of stars that lived in the ancient universe. In recent...

Precious metals like gold, silver, platinum, and rhodium are expensive because they're rare in Earth's crust. But are they rare in the universe? Why is it so hard to make some of the chemical elements? Where do heavy metals come from,...

Seemingly distant ecosystems, even half a world apart, are connected in surprising ways. In this special limited series, Emily Graslie and Trace Dominguez join me as we explore the universal rules of life that tie together Earth’s living...

Explore the four biomolecules and their importance for organisms and the structure and function of their cells! This 2023 UPDATED Biomolecules Amoeba Sisters video has some more detail and improved art from the 2016 Amoeba Sisters...

Scientists working at a nuclear fusion facility in Oxford announced a record-breaking result. And while there's still a lot to figure out to make fusion viable, this brings us one step closer to realizing a technology with huge potential...

This week's SciShow news brings you discoveries involving two of the most exotic substances on Earth - the world's rarest element and the world's oldest water. Two great tastes that taste great together? Stay tuned to find out.

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...
