Is there life beyond earth? Join NASA's director of planetary science James Green for a survey of the places in our solar system that are most likely to harbor alien life.

By giving some fossils a dental exam, we've learned more about how tusks first evolved. And humans aren't the only primate that can get down at karaoke night.

"Rock-star physicist" Brian Cox talks about his work on the Large Hadron Collider at CERN. Discussing the biggest of big science in an engaging, accessible way, Cox brings us along on a tour of the massive project.

This video focuses on general functions of biomolecules. The biomolecules: carbs, lipids, proteins, and nucleic acids, can all can have important functions in the body. However, this video is not giving human dietary guidelines and...

Hank talks about a shiny element that has fascinated humans for millenia.

In this video Paul Andersen shows you how you can use modeling to have your students construct explanations in the science classroom.

Architect Joshua Prince-Ramus takes the audience on dazzling, dizzying virtual tours of three recent projects: the Central Library in Seattle, the Museum Plaza in Louisville and the Charles Wyly Theater in Dallas.

The sun may have thousands of stellar siblings, many of them probably just like it, elsewhere in the galaxy. Find out how astronomers are looking for them, and learn about a match that could be our star's long-lost sibling!

The event that gave us our moon may have also given us the elements necessary for life and scientists might have found a very tiny piece of our solar system's past way out in space.

In Islamic culture, geometric design is everywhere: you can find it in mosques, madrasas, palaces, and private homes. And despite the remarkable complexity of these designs, they can be created with just a compass to draw circles and a...

Scientists are learning new things by looking at the remains of exoplanets, NASA has unveiled a new spacesuit design, and engineers fixed a problem from one hundred million kilometers away.

Massive stars die in fantastic explosions called supernovas. Most of them fit neatly into a few categories, but then there are the peculiars, a special group of supernovas that don’t quite fit in with the rest.

Carl Sagan famously observed that we are all made of "star stuff." But what does that mean? And how much of you is really made of dead stars? SciShow Space explains!

In the quest to build colonies in space, one major hurdle to overcome getting materials for construction to the places they'll be needed. One of the most promising techniques for solving this problem involves some extraordinary space...

Most of us can probably think of a time when we were enjoying a video game and then suddenly...it's 2 am. And that may not be entirely your fault! Video games are designed with elements that suck you in and put you in a state of flow,...

Explore the cycling of carbon among carbon reservoirs! Then discover the importance of nitrogen, essential for amino acids and nucleotides, and learn about the nitrogen cycle! Expand details for table of contents. Table of Contents:...

Backed by stunning illustrations, David Christian narrates a complete history of the universe, from the Big Bang to the Internet, in a riveting 18 minutes. This is "Big History": an enlightening, wide-angle look at complexity, life and...

Mathematics explains the workings of the universe, from particle physics to engineering and economics. Math is even closely related to music, and their common ground has something to do with a Rubik's Cube puzzle. Michael Staff explains...

Hank introduces us to the man behind the periodic table - the brilliant Russian chemist Dmitri Mendeleev.

Massive stars fuse heavier elements in their cores than lower mass stars. This leads to the creation of heavier elements up to iron. Iron robs critical energy from the core, causing it to collapse. The shock wave, together with a huge...

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!

We don't think of pocket calculators as being all that special these days, but in reality their rise coincided with many of the innovations we take for granted today.

If you needed to tell someone what numbers are and how they work, without using the notion of number in your answer, could you do it?

Over the years, people have come up with some truly awful apologies. From classic non-apologies, to evasive excuses, and flimsy corporate promises, it's all too easy to give a bad apology. Good apologies generally share certain elements,...
