You probably know about the geomagnetic field that protects the earth from solar storms and radiation. But precision satellites have measured ANOTHER magnetic field coming from Earth, and its signals might hold the key to searching for...

If, for some wild reason, we decided that breeding humongous spiders was a good idea, could we actually pull it off?

With their squishy bodies and color-changing abilities, octopuses and other cephalopods already look like our planet’s resident aliens. But researchers have discovered yet another thing that separates them from most other animals on...

Hank talks about why it is so difficult for scientists to predict earthquakes in the short term.

Hank talks about astrobiology - the study of and search for life in the universe off Earth. Right now, the field has more questions than answers, but all they all seek to answer that one fundamental query: are we alone in the universe?

The ocean is the largest ecosystem on Earth, but it's still mostly unexplored. This is partially due to the challenges of ocean exploration, like bone-crushing pressure and the need to bring your own air. But here are five ways that...

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

Hank tells us the stories of three experiments in biology that, with creativity and luck, changed science & the world with it in their work to solve the mysteries of the universe.

3 Surprising Things Matter Does Under Extreme Pressure

Fossils can provide clues to the conditions that ancient species lived in, like what their environments felt like, how deep in the water some species lived, or even how long the Sun was out!

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.

How different would things be if Earth had always rotated in the opposite direction? Hosted by: Stefan Chin

What could be cooler than a permanent lava lake surrounded by snow!?

GPS devices aren't just for keeping you from driving into a lake. They're also helping lots of scientists in unexpected ways.

Potato spindle tuber disease wasn't a life-or-death situation, but it led to the discovery of viroids: infectious, replicating bits of RNA

Scientists think they’ve discovered some peaks taller than Mt Everest deep beneath the earth’s crust, and this range might be the key to one of the biggest mysteries in geology!

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...

There are still several fascinating mysteries of our universe unsolved by scientists even after decades and even centuries of research! Join Olivia Gordon for a new episode of SciShow and learn about these seven weird phenomena that...

There are some geological areas on the planet that scientists still don't understand. For most things it's pretty clear—combine a volcanic eruption a dash of erosion, and boom, you’ve got a striking cliff! But not all the features on...

So what exactly do magnetic fields actually do? What would happen if they went away? Turns out, it could be catastrophic! SciShow will explain it all in this fun new episode hosted by Michael Aranda!

Learn how magnetic bacteria work, and how scientists think they can help technology in the future!

What's the awesomest place in the world? Scientists can think of at least 137, the newly released list of the most biologically important places on Earth. Hank explains how ecologists arrived at this list, and takes you on a tour of four...

Hank's news this week informs us on a couple of crazy science experiments, updates us on some earlier topics (dangerous asteroids and ancient phallic rock art), and briefs us on a new study that seeks to find the evolutionary origins of...

Hank describes how astronomers used a technique called gravitational lensing to find the most distant galaxy ever detected -- and how NASA is embarking on a new program to use this same technique to peer deeper into space than ever...
