If you think it's cold outside where you are, you should try living in the coldest place on Earth: Antarctica! Learn why it's a desert even though it's very cold, and about awesome animals like seals and penguins.

In the millions of years since oxygen began saturating Earth’s oceans and atmosphere, most organisms have evolved to rely on this gas. However, there are some places where oxygen-averse microorganisms like those from Earth’s earliest...

Even when animal traps are humane, it seems pretty obvious that animals wouldn't want to get caught. But sometimes, there are oddballs that love getting trapped. Here's what we know about what can make some animals so darn trap happy.

Anthony Tan — the CEO of Grab, Southeast Asia's leading super-app — talks about launching a business that not only turns a profit but also helps people and the environment. In conversation with digital strategist Amane Dannouni, Tan...

I was in Arizona recently for Phoenix Comic-Con, and had the amazing pleasure of seeing one of Earth's greatest natural wonders… the Grand Canyon. More than a mile deep, and several miles across, it just defies belief. But I couldn't...

Why can't laptop screens be viewed outside like e-readers can? It turns out, they use very different technology. But engineers are working on closing the gap.

Recently, a group of scientists have declared that the start of the Anthropocene, the time of outsize human influence on Earth, to be Crawford Lake in Canada. But how can a time be a place? We'll explain, and maybe grab some maple...

Paleodictyon, a hexagonal-patterned fossil, is a bit of a mystery. We don’t even know if it’s a trace fossil, or the organism itself. So… what could it be?

In 1926, Robert Goddard launched Nell — the very first (successful) liquid fuel rocket. But Nell wasn't built like other modern rockets, including a notable lack of casing and an exhaust nozzle suspended above the propellant tanks.

This video is about what happens if you try to pass a portal (like in the video game Portal or Portal 2) through itself - do you get a paradox? Infinite recursion? Impossibility? Contradiction? The end of the world? Collapse of the...

Oxygen is pretty great stuff, but this recently discovered organism couldn’t care less about oxygen. It breathes nitrogen and may offer a window into how the types of cells in OUR bodies may have evolved billions of years ago.

Monsoons are more than torrential rains. They come in wet and dry varieties, but both involve a lot of wind. And it turns out, those winds can help the Earth clean up some of the pollution mess humanity makes.

This week, CERN announced a new particle that will help further understanding of the fundamental forces, and a simulation of ancient creatures may give us a clue as to how life grew beyond the microscopic.

If you’re trying to figure out where to plan on sheltering during the zombie apocalypse, it’s essential to know whether zombies sink or float!

Carbon is fundamental to life on Earth. And it goes through a complex cycle, from up in the atmosphere, to the depths of the ocean. But down there, the carbon trail gets harder to follow. Or at least, it was that way until this little...

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!

Roller coasters give people the opportunity to experience physics in dramatic ways. In this episode of SciShow, we break down how physics work on roller coasters to give you the ride of your life!

Hank hits you with a ton of news this time - Amazon CEO Jeff Bezos has plans to retrieve Saturn V rocket engines from the bottom of the Atlantic; new research on the impacts from the Deep Water Horizon oil spill to life in the Gulf of...

New evidence suggests some fossils as the oldest known sign of life on Earth, and scientists may have a way to speed up the process of carbon neutralization in the ocean!
