Most animals on earth are bioluminescent, but almost all of them live in the ocean - and scientists aren’t sure why.

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.

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.

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.

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...

This week, scientists think they may have found a missing link in regards to how plants went from living in the sea to on land, and also, in adorable news, surfing honeybees.

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.

The oceans absorb a lot of CO2, leading to a variety of effects like ocean acidification. But you might not expect one of those effects: stronger lightning strikes.

You might want a really sturdy umbrella to dig into this video, because we’re discussing 5 animals that have a tendency to rain down from the sky and the reasons we think this might be happening!

What do you see in clouds? Bunnies? Zombies? The face of Nic Cage? There are some kinds of clouds that, while rare, make even weirder shapes -- like pancakes, rolling cylinders, and shimmery rainbows

There are wild hybridizations happening all the time! Here are five weird and wild hybrids that aren't just cool but could teach us something too. Hosted by: Hank Green (he/him) 0:00 Intro 1:06 Arctic Oddballs 3:43 Bouncing Baby Bears...

Meet the Duke of Burgundy, a species of butterfly that was saved from certain doom, thanks to a bridge.

Dinosaurs were huge—it's common knowledge. So why aren't modern mammals anywhere near that size? In this episode of SciShow, Hank gives a quick run-down of the reasons scientists think the land mammals of today are nowhere near the size...

Roots do more than hold plants in place -- they hold the planet in place. They're an important defense against drought and climate change, and of course, our actions are changing them.

Though we probably won’t find a literal Atlantis beneath the sea, that doesn’t mean that a human settlement hasn’t ever been lost to the water. Meet Doggerland.

You may have thought that crocodile tears were just a figure of speech, but it turns out they're real, and may help those of us with dry eyes.

There’s a reason behind the saying “fish out water.” Fish don’t tend to do well if they’re not immersed in liquid. But walking catfish are surprisingly adept at making their way on land.

Have you ever wondered how our earth was created? Here is a brief history about the Earth.

We know these glaciers are already on the way out, so we need to find out whether we can bulk them back up again. For that, we turn to the glaciers’ past – and a lot of penguin bones.

Scientific discovery often dabbles in the extreme, challenging and exceeding what we think of as "possible." And this year's discoveries were no different! We present to you three scientific discoveries made this year that set out to...

Jen Fowler of the Montana Space Grant Consortium joins us this week to talk about her work with weather balloons and the upcoming solar eclipse, and Jessi from Animal Wonders brings along Gaia the Southern Three-Banded Armadillo!

Plants make oxygen using photosynthesis, but what happens to the air when those trees drop their leaves in winter?

Photosynthesis plays a huge role in regulating the earth's CO2. But what happens when the temperature gets high enough that photosynthesis slows down?

When it comes to mass extinctions, you probably imagine giant volcanic eruptions or asteroids raining fire from the sky, but sometimes these events can have some unexpected causes. Hosted by: Michael Aranda
