This lake in Canada sports a stunning summer look - spots! And the weird geology and hydrology that makes these spots is definitely worth talking about. Plus, Spotted Lake may not be the only one of its kind, and might tell us more...

As the waters warm in the deep sea around Antarctica, ecosystem-crushing crabs are able to live closer and closer to the continent.

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.

Magnesium may be all the rage as a sleep aid, but does it actually work? We decided to dive into the research to find out, and ended up learning a lot about mice along the way.

So we all know about the carbon cycle, and the water cycle, and maybe even the nitrogen cycle. But new research has figured out there's a salt cycle, too. Problem is, that same research has found that we already broke it. Here's what...

Icy roads are a huge hazard, and typical methods of de-icing them can be pretty toxic to wildlife. Which is why researchers have been so fixated on finding better alternatives, from brine to pig pee.

When we think of the ocean and what's in it, you probably think of stuff like fish, or salt, or seaweed. But there's a crystal that is so vital to marine life that they take dissolved materials in that salty water and build 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.

If salty water is constantly spilling into the world’s oceans, does that mean they are getting saltier by the day?

Fossils can provide clues to the conditions that ancient species lived in, like what their environments felt like, how deep in the water some species lived, or even how long the Sun was out!

If you've ever wondered why you crave certain foods or what your appendix actually does, there's something in this collection for you!

From towering mountains to pebbles along a river, the Earth is made of a huge variety of rocks. In today's episode, we're going to follow the rock cycle of a piece of granite in the Himalayan mountains, and as you'll see, every rock has...

SciShow News takes you to the depths of the Earth, where the world’s most abundant mineral is found, and to the Arabian Sea, where a strange population of whales has been living in isolation for 70,000 years!

Fossils can provide clues to the conditions that ancient species lived in, like what their environments felt like, how deep in the water some species lived, or even how long the Sun was out!

Massive amounts of dust manage to travel all the way across the ocean, creating some powerful and surprising global effects!

Astronomers have found a Hot Jupiter - WASP-121b - that is leaking metal, and put together a new 3D map of the Milky Way showing that our galaxy is actually a bit twisted!

In this week's SciShow News, we discuss two new types of sensors being developed. One tracks the content of certain molecules in your sweat while you exercise and the other is a brain implant that can be resorbed once it has finished its...

Atoms or molecules combine to form a new compound in a synthesis reaction. Examples include the addition of oxygen to magnesium metal to create magnesium oxide and the addition of carbon dioxide to water to crete carbonic acid. A...

There’s no doubt that lithium has a diverse list of uses. But the way that it interacts with our bodies to help treat bipolar disorder is aiding us in better understanding the disorder and potentially developing new drugs to combat it.

The world needs clean water, and more and more, we're pulling it from the oceans, desalinating it, and drinking it. But what to do with the salty brine left behind? In this intriguing short talk, TED Fellow Damian Palin proposes an idea:...

You come home from an intense workout, muscles aching, and lower yourself into a warm epsom salt bath from some sweet relief. But are all those extra minerals really helping soothe your pain?

Why do I really, really want ice cream right now? Today we explore the science of food cravings!

In this video Paul Andersen explains how redox reactions are driven by the movement of electrons from the substance that is oxidized to the substance that is reduced. Oxidation is the loss of electrons and reduction is the gaining of...

For life to evolve on Earth, a bunch of complex organic molecules had to evolve a way to assemble into cells. So how did those proto-cells get cell membranes? Some researchers have a new hunch. Also, scientists are borrowing a trick from...
