Alaska has the most volcanoes out of all the US states, but researchers think they don't have enough. Here's the weird science behind looking for Alaska's volcanoes, and what we've learned about volcanism along the way.

On the Internet, koalas get an unnecessary amount of hate, so let's debunk some of the most pervasive koala myths!

When does vision loss become blindness? Writer, audio producer and editor Andrew Leland explains how his gradual loss of vision revealed a paradoxical truth about blindness -- and shows why it might have implications for how all of us...

Lots of geological forces need to come together for continents to form, but they all require one ingredient: water.

If you can find a phone book these days, science is here to help you rip it in half with your bare hands!

Mountains may look like they've all been stagnant for thousands of years, but the life cycle of a mountain is actually quite fascinating. From mountain ranges in space, to why Earth isn’t a water-world, here are some videos exploring the...

In the early 20th century, Alfred Wegener's theory of Continental Drift laid the foundation for our modern theory of plate tectonics. And today we know something even more exciting: Pangea was only the latest in a long lineage of...

What should a community do with its unused land? Plant food, of course. With energy and humor, Pam Warhurst tells at the TEDSalon the story of how she and a growing team of volunteers came together to turn plots of unused land into...

It’s amazing how professional baseball players can throw very fast curveballs, but do you know how do curveballs change direction in midair?

We use seismographs to record the time, location and magnitude of earthquakes as they happen. But in the last three decades, a new field of study has emerged that is learning to track these details about earthquakes of old using the...

You may wish that you could pack on a few pounds and sleep the next few months away, and scientists are one step closer to understanding how some animals are capable of doing this.
