In which John Green teaches you about nonviolence and peace movements in the 20th century. What is nonviolence? What is a peace movement? Well. traditionally, humans often resort to violence when they come into conflict. In the 20th...

There's a complex, mysterious current running throughout the Atlantic Ocean, and it's in trouble. But to help save it, researchers need to understand it, and finding ways to study it has been a challenge. But it turns out that the...

Today, the Great Salt Lake of Utah has multiples of the ocean's salt concentration. But it didn't used to be so salty. In fact, it used to be Lake Bonneville. And we know its story thanks to microscopic diatoms and Dr. Ruth...

China's Red Beach is a stunningly beautiful tourist destination. But the plants that make Red Beach red are hiding a secret -- one that could save other wetlands, if we can save this one first. <br<br/>/>

Humans have been transforming seawater into potable freshwater for millennia. Today, billions of people can’t access clean drinking water, and 87 different countries are projected to be “water-scarce” by 2050. So, how can we use seawater...

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.

Our oceans don’t technically contain salt, but the ions salt is made of play a critical role in planet-wide processes that make the Earth habitable.

Today, Jessi and Squeaks learn about the Maillard reaction while they make some delicious caramel.

How could a body of water as big as the Mediterranean just...disappear? It would take decades and more than 1,000 research studies to even start to figure out the cause -- or causes -- of one of the greatest vanishing acts in Earth’s...

Refrigeration and air conditioning are among the largest sources of carbon, and the refrigerants we use are greenhouse gases, too. But green refrigerants are on the way, from elastocaloric cooling to a method a bit like salting an icy road.

In the hunt for life beyond Earth, scientists shouldn't skip over frozen planets. In some cases, ice might actually help life evolve!

Today, NASA announced that there is...occasionally...flowing, liquid water on the surface of Mars. What?!

They live in the water, but do they actually drink it? Turns out, some fish actually do! Learn all about how different kinds of fish get the fresh water that they need to survive in this new episode of SciShow!

Gargling with warm saltwater for a sore throat is a remedy commonly known and loved by doctors, and there is some evidence to back it up, but it’s not a cure.

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

You probably know about the geomagnetic field that protects the earth from solar storms and radiation. But precision satellites have measured ANOTHER magnetic field coming from Earth, and its signals might hold the key to searching for...

So, moose licking cars in winter is a thing, if you live in a place that has both moose and winter. But why on earth do they do this?!

Squeaks, Jessi and Anthony are spending a bunch of time learning all about the wonders of caves in this compilation video!

Squeaks went on a trip to the beach, and wants to tell Mister Brown all about it! And, we can learn all about the science that formed the beach, plus a guest appearance by Grady the tardigrade to talk all about the plants and animals in...

Health correspondent Betty Ann Bowser talks to author Dr. David Kessler about overeating and what is behind people's cravings, the subject of his new book, "The End of Overeating."

The demand for electric vehicles is surging in the U.S., sparked in part by the Biden administration’s Inflation Reduction Act and the subsidies it offers. But a looming supply shortage of lithium threatens to stall the EV transition....

As we construct more complex organic molecules, it can start to feel like decrypting a complex code. Organic synthesis takes simple starting materials, and turns them into complex structures, and reverse engineering can help us figure...
