Why Does Earth Have Deserts? For the same reason it has Rainforests: Hadley Cells!!!

Could an edible computer be in your future? Researchers are currently working on several of the components you find in them, from batteries to circuit boards to logic gates.

Yes, you need to take breaks at work. Not only is resting good for your brain — it might even make you more creative. Here are consultant Alex Soojung-Kim Pang's four tips to help you step away and return to your job with more energy to...

If there’s one thing cooler than a black hole it’s a rotating black hole. Why? Because we can use them as futuristic power generators, galactic-scale bombs, and portals to other universes.

Black holes are self-sustaining...

Ever wish you could travel backward in time and do things differently? Good news: the laws of physics seem to say traveling backward in time is the same as traveling forwards. So why do we seem to be stuck in this inexorable flow towards...

Black holes are about the worst subjects for direct study in the universe. But at this stage, it’s all we can do to convince ourselves of their existence. Actually studying the physics of real black holes is much, much harder. I mean, we...

The weird rules of quantum mechanics lead to all sorts of bizarre phenomena on tiny scales— particles teleporting through walls or being in multiple places at once or simultaneously existing and not. Shame all this magical behavior...

We know that gravity must cause clocks to run slow on the basis of logical consistency. And we know that gravity DOES cause clocks to run slow based on many brilliant experiments. But I never explained WHY or HOW gravity causes the flow...

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...

Flow is more than just concentrating or paying attention; it's a unique mental state of effortless engagement. And those who more frequently experience flow report higher levels of positive emotions, creativity, and feelings of...

Methuselah’s environment lacks nutrients, water, and oxygen. In other words, it’s the perfect place to grow very very old.

Did you know that last year we had 28 of the fastest days ever recorded? Earth's rotation can be affected by a number of things, and scientists think we might someday need an unprecedented adjustment: deleting a second!

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!

Can you imagine a cup of tea that doesn't obey the laws of physics? One that pours out of the bottom of your cup while crawling up the sides to the top? Join Hank Green for a fun new SciShow super episode all about superfluids!

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...

3 Surprising Things Matter Does Under Extreme Pressure

Pelagic red crabs are actually lobsters - and that’s not even the weirdest thing about them! They sometimes wash up on shore in droves, signaling large scale climate events like El Niños and serving as a warning to marine biologists of...

SciShow explains how SciShow exists -- and everything else that's ever been made or used on a computer -- by exploring how transistors work together in circuits to make all computing possible. Like all kinds of science, it has its...

Caves are fascinating, but these ones are some of the most fascinating, both in and out of this world. Hosted by: Stefan Chin

You'd think that air that was the same temperature as your body would feel neutral, but if you've ever been outside when it's 37 degrees Celsius out... you know that's not the case! Hosted by: Stefan Chin

Like dolphins, manatees, and other marine mammals, whales have nipples hidden in surprising places.

What comes to mind when you think about the most fun moments of your life? Science journalist Catherine Price asked thousands of people across the world this question, and their answers led her to a new definition of "true" fun: a...

We all know the words around electricity -- _charge," _positive," _battery" and more. But where do they come from and what do they really mean? Let the history of these words illuminate the physics of electric phenomena.

Hank brings us another simple experiment that demonstrates the important biochemical process of osmosis by turning a chicken egg into a frightening alien-looking thing.
