The rise of the Himalayas affected more than just the immediate area. Turns out, we may have them to thank for everything from the rise of giant flightless birds in Madagascar; to the disappearance of plants from Antarctica; to the...

There's a few minerals that exhibit something called piezoelectricity and pyroelectricity, which mean that either heat or pressure can turn them electric. Here's a demo from the SciShow Rocks Box where you can see this for yourself - all...

It's no secret that cold can help treat a source of pain, like a sprained ankle or even a burn. But new technology might be able to take that principle and apply it /directly/ onto your nerves!

Throughout the Pleistocene Epoch, the range of the woolly rhino grew and shrank in sync with global climate. So what caused the climate -- and the range of the woolly rhino -- to cycle back and forth between such extremes?

The Toba supervolcano was the biggest explosive eruption of the last 2.5 million years. And humans were around to see it, or at least feel its effects! But what were those effects?

As the Earth warms due to human-caused climate change, billions of people in the developing world will face life-threatening heat waves, raising the demand for air conditioning. But powering all of that cooling is going to take more...

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.

Nuclear war is a terrifying existential threat, but we shouldn't only fear the blasts because the ensuing smoke is the real killer.

A special experimental white paint that recently made it into the Guinness<br/>
World Records could one day help keep the world from heating up<br/>. John Yang

When you think of a frozen object in space, you might think of Pluto, but stars themselves actually freeze.

In addition to just being beautiful one-of-a-kind panoramas in the sky, clouds can tell us so much about how energy and weather patterns flow around the globe. Today, we'll talk about how clouds form, the three main types (cirrus,...

Volcanoes can show nature's rage. What are the biggest eruptions we've witnessed in our history?

The way we cool things down is heating the planet even more, says sustainable development expert Rachel Kyte -- and the solutions go well beyond just fixing air-conditioning. She identifies four major areas with transformative solutions...

We’ve developed thousands of technologies for space exploration, but luckily for us, sometimes those solutions apply to problems here on the ground, too.

You’ve seen dogs pant, but do you know why they do it? And is it true that dogs can’t sweat? Quick Questions has the answers!

A summertime look at why we sweat, why we burn, and why our fingers wrinkle in the pool

The InSight lander is finally launching and headed to Mars, and Hubble has revealed some hot supernova info.

As we recklessly warm the planet by pumping greenhouse gases into the atmosphere, some industrial emissions also produce particles that reflect sunshine back into space, putting a check on global warming that we're only starting to...

Hot off the presses, this week has been cool! Researchers have discovered the first room-temperature superconductor, and another group has created a type of paint that actually stays cooler than the environment around it!

Throughout Earth's history, climate has varied greatly. For hundreds of millions of years, the planet had no polar ice caps. Without this ice, the sea level was 70 meters higher. At the other extreme, about 700 million years ago, Earth...

If you shave regularly, you may have noticed your razor blades don’t cut as well after just a few uses. But why do razors get dull so quickly?

The coldest materials in the world aren't in Antarctica or at the top of Mount Everest. They're in physics labs: clouds of gases held just fractions of a degree above absolute zero. Lina Marieth Hoyos explains how temperatures this low...

This video is about compressed air cans (aka gas dusters) and why they get cold when you spray them. They cool off because the refrigerant inside (1,1-difluoroethane) is under pressure and boils off when the...
