New ReviewA new friend Savannah and Sam learn about different kinds of igneous rocks, which form after liquid magma or lava cools into solid rock.

Hollywood (and other fictional media) loves to show people dying in outer space. And it has several go-to causes of death, on a sliding scale of accuracy. But it turns out, reality has some ways to kill you that are far stranger than...

One fun fact about elephants is that they're a lot less likely to get cancer than other animals (including us). Another fun fact is that unlike most warm-blooded animals, their testes are deep inside their bodies. It turns out, these two...

In 2021, researchers reported a shocking disappearance in the Bering Sea. Not of people, but of Alaskan snow crabs. And it's taken scientists years to understand how tens of billions of crabs disappeared all at once, so let's take you...

Back in the Victorian Era, Englanders thought that the famous Roman Baths were so healing because there was radium in the water. And there was, but that wasn't the real secret. Turns out that the baths are teeming with microbes that...

Life on Earth has weathered boiling-hot oceans and volcanic-ash-darkened skies—but that’s nothing like the climate change we’re experiencing now. In this episode of Crash Course Biology, we’ll talk about the greenhouse effect, learn why...

Industrial manufacturers spend a huge amount of energy generating heat to make everyday materials and objects, like cement, steel, and paper. And since most companies use fossil fuels to reach these high temperatures, industrial heat...

The sprawling metropolis of Phoenix seems an unlikely place to build an apartment complex without parking for residents. Car dependency is just part of life for most people there. But a new development in the suburb of Tempe is providing...

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...

Despite the seemingly basic things we don't know about dinosaurs, we do know some surprising things – like their body temperatures.

Venezuela’s Lake Maracaibo is home to a legendary lightning storm that has been going on for over 500 years.

Insects are the world’s most numerous and diverse animals. Even where you’d least expect them in some of Earth’s most extreme environments, there they are. From a scalding volcano, parched desert, to a frigid glacier, insects are living...

From its life-sustaining energy to its explosive geomagnetic storms, the Sun has many mysteries, says astrophysicist Nour E. Rawafi. He sheds light on NASA's latest endeavor to better understand our fiery neighbor and its impact on the...

In 1997, a fire began in Indonesia that would rage for almost a year. Despite being one of the largest fires in recorded history, for months at a time it burned without a flame. This might sound like a uniquely freaky fire, but it’s...

In many parts of the world heat waves are happening more often with greater intensity and for longer durations. By 2050, Earth’s mid-latitudes could be experiencing extreme heat between 90 and 180 days a year, with tropical regions...

How is the chemical energy of gasoline transformed into kinetic energy of a moving car? And where does that kinetic energy go when the car crashes into something and stops moving?

How to Turn Sound Into Light - Sonoluminescence

Magnets are amazingly strong... but there's a very easy way to destroy them. All you need to know is a little bit about ferromagnetism, paramagnetism, and temperature!

Why is it Hot Underground

Want to learn more about the topic in this week's video? Here are some key words/phrases to get your googling started: - Lifting Condensation Level (LCL): The altitude at which the water vapor in rising air begins to condense - Adiabatic...

Jessi and Squeaks explore two of the windiest places on Earth: Mount Washington in New Hampshire, USA, and Commonwealth Bay, Antarctica.

Typically, with any piece of technology, you pump one unit of energy in and you get about one out. That’s just the first law of thermodynamics: energy has to be conserved. But there’s a piece of technology called a heat pump, where for...

Stars have cores hot and dense enough to force atomic nuclei together, forming larger, heavier nuclei in a process known as fusion. In this process, the mass of the end products is slightly less than the mass of the initial atoms. But...
