We actually have no idea what a “disease” is.

Plants don't make caffeine just for us, so what DO they make it for?

It’s common to call creepy crawlies bugs, but because entomologists refer to a specific class of insects as bugs, it’s wrong to call other things bugs - right?

By overcounting how much carbon their forests suck up, and undercounting how much carbon their industries release, countries undercount their total carbon emissions.

Watch these amazing rewilding videos from our friends at Planet Wild, in which they’re saving Europe’s cutest bird from extinction or resurrecting a dying forest.

This video is about the physics of geosynchronous and geostationary orbits, why they exist, when they don't, when they're useful for communication/satellite TV, etc.

In this episode, we discuss the basic nature of gravity, one of the four fundamental forces in our universe.

One Minute Physics provides an energetic and entertaining view of old and new problems in physics -- all in one minute!

This video covers the General theory of Relativity, developed by Albert Einstein, from basic simple levels (it's gravity, curved space) through to the concepts of how curved spacetime is represented by psuedo-Riemannian manifolds with...

Once upon a time, there was a lake that was so radioactive, that standing on its shore for more than an hour would almost definitely kill you. Join Olivia to learn how it got that bad in the first place, and what was done to fix it!

Does your toilet water drain differently than in the other hemisphere? Is it because of the Coriolis effect? Hank has some things to clarify about these questions, and more in this edition of I Don't Think It Means What You Think It Means.

When you learned about the Earth’s interior in school, you were probably shown a diagram that looked like a perfect layer cake. But we've known for a long time that that diagram is... inaccurate at best, and leaves out information that...

Researchers have found ancient communities of microbes that have been buried deep, for a hundred million years! This discovery might be the oldest living thing on Earth, and could even expand the search for life on other planets.

A volcanic eruption and series of earthquakes in 2005 were important not because they did a great deal of damage to humans, but because they’re geologic evidence of where Earth’s next ocean will most likely pop up.

One of the toughest materials known to science is made not by humans, but by nature... and it's inside of oysters.

Dickinsonia might be the oldest known member of the animal kingdom, and the origin of birdsongs from the syrinx might be a little less mysterious.

When you think about the impact of climate change on the circle of life, you likely picture polar bears or Bengal tigers struggling in new conditions. But the impacts on the world go all the way down to the tiniest creatures who do some...

Did you know that a massive ancient flood triggered a thousand year ice age? 13,000 years ago, North America seemed to be thawing from a 2.6 million-year ice age. Then, a huge swath of Earth was suddenly plunged back into the cold for...

Thanks to the Monterey Bay Aquarium and their research and technology partner MBARI for partnering with us on this episode of SciShow. They worked together on an exhibition, “Into The Deep: Exploring Our Undiscovered Ocean,” to give...

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.

We’re all excited about the Mars rover Perseverance this week, but scientists are also working on some other exciting things!

Today, NASA announced that there is...occasionally...flowing, liquid water on the surface of Mars. What?!

For the last hundred and fifty years or so, geologists have been trying to wrap their heads around the mystery: in some places, the geologic record just seems to jump by over billion years. And last week, a paper was published that may...
