People have been trying to make the prettiest colors we can for thousands of years. And sometimes, we've even used poison to do it. From lead white to arsenic Scheele's green and cobalt violet, here are just a few of the most toxic...

About 99.9% of your typical human body is made of just 11 elements from the periodic table. But hiding in that remaining 0.1% are some elements that do some very important jobs to keep you alive and healthy. Including some elements you...

Giant disks around baby stars filled with gas and dust provide the material to make all sorts of planets, and new evidence proves that our solar system’s had a massive gap in it! And the water vapor in Jupiter’s moon, Europa, might not...

From corundum to alexandrite, there are rare minerals have multi-colors caused by how they form their structure!<br/>

How do magnets work? Why do they attract and repel at long distances? Is it magic? No... it's quantum mechanics, and a bit more, as we explain in this, the longest MinutePhysics video ever.

Howcast - Learn what you need to know about chromium picolinate from registered dietician Glen Tobias in this Howcast video.

If you like things shiny and bright, you're probably a fan of chromium, a metal used to plate other metals, commonly known as chrome.

Transition metals are elements in the d orbital. The reason these are unique is that they do not have 1 set charge they become when they become an ion like elements in the s and p orbital. Elements in the d orbital, or our transition...

Materials can be classified based on their response to external magnetic fields. Diamagnetic materials are weakly repelled by external magnetic fields, while paramagnetic materials are attracted but lose their magnetism in the absence...
