Hydrothermal vents are some of the most extreme environments on the planet. But in 2000, scientists discovered a vent unlike any other, one that spews white smoke and is 10 times older. And some think it may help us understand how all...

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.

In this video Paul Andersen explains how inertial mass is defined and measured. When a force is applied to an object or a system it will accelerate. Using Newton's Second Law of Motion (F=ma) you can calculate the inertial mass.

The Earth is 4.6 billion years old -- but how can humans relate to a number so colossal, and where do we fit on the geologic timeline? Comparing the Earth's lifetime to one calendar year, events like the extinction of dinosaurs and...

How To Detect A Secret Nuclear Test

Floods, droughts, heat waves and cold blasts -- why is the weather becoming more extreme? Environmentalist and "America's weatherman" Al Roker discusses the link between climate change and disruptions to weather patterns worldwide,...

About 5 million years ago, a new predator made its way from the south and onto the coastal plains of North America. It was a giant, flightless, carnivorous bird and came to be known by one of the coolest and most richly earned nicknames...

Plenty of good things are done in the name of religion, and plenty of bad things too. But what is religion, exactly — is it good or bad, in and of itself? Philosopher Kwame Anthony Appiah offers a generous, surprising view.

Find out about China's current telescope on the moon and what the future plans are for mounting larger telescopes on the lunar surface.

Chlorofluorocarbons, or CFCs, seemed too good to be true when they were first created, and before long astronomers studying Venus' atmosphere discovered what could go wrong with this "miracle molecule."

Scientists have been searching for alien life by honing in on the existence of liquid water, but we might be overlooking some types of life out there that doesn't need water at all.

Scientists studying Comets 67P and Lovejoy have discovered oxygen, alcohol, and the building block of sugar. Sounds like a regular Friday night on earth, but it’s the first time we’ve found any of these things on a comet.

This video is about how we don't just need energy to power our lives, we need *low entropy* energy! Thanks to Google Making and Science for supporting this series, and to Sean Carroll for collaborating on it!...

For some forms of live, old-age is relative.

Our understanding of the world has to start somewhere! And while early ideas like the Hollow Earth Theory are mostly wrong and sound silly to us now, that doesn’t mean they weren’t important.

When it comes to water on Earth, life finds a way. Even in the hottest, most acidic, and saltiest waters in the world, odds are you'll find some kind of organism adapted to live in it. There is, however, a place with water so extremely...

SciShow takes you on a tour of Canada’s Bay of Fundy, home of the largest tidal range in the world.

Explore the origins of one of the coolest geologic formations in the world, West Africa's Richat Structure.

The universe is made up of information, similar to a computer, and physics (you know, the basis of the universe) certainly is based on computational principles. But is it running some grand program? Will the answer be 42? Make sure you...

Antarctica is a vast and dynamic place, but radar technologies -- from World War II-era film to state-of-the-art miniaturized sensors -- are enabling scientists to observe and understand changes beneath the continent's ice in...

We can now map the interiors of stars by "listening" to their harmonies as they vibrate with seismic waves.

In 2009, a satellite circled Earth, scanning and sorting the wavelengths reflecting off the planet's surface. Researchers noticed something baffling: an unexpected wavelength of unknown origin. They tried looking at Earth with only this...

Obviously most telescopes need to see the sky to do their job, but when you are studying a wave that can pass right through the earth, the best place for your telescope might be underground.

So... what makes the wind? You might be surprised to learn that it has to do with two of Earth's spheres; The Hydrosphere and the Geosphere. In this episode of Crash Course Kids, Sabrina takes us to the beach to chat about how the wind...
