Despite their name, rare earth elements (REEs) are a relatively abundant group of 17 metallic elements.

Silicon is the backbone of the semiconductor industry, but it's also interesting in its own right. Here's why it's so important in modern computing—and in many other applications.

Earth-size planets can have varying amounts of radioactive elements, which generate internal heat that drives a planet’s geological activity and magnetism.
