Archaeologists working at a desert site in Jordan have excavated a large and very well-preserved copper factory from the Early Bronze Age. The discovery is providing insight into metal production as the first urban cultures emerged.

A team of scientists says evidence from fossilized leaves indicates that dinosaurs appear to have become extinct as a result of the catastrophic impact of an asteroid and not volcanic activity.

Dinosaurs, along with an estimated 70 percent of all life on Earth, are believed to have gone extinct 65 million years ago as a result of a series of dramatic temperature changes. The extinctions are known as the K-T extinctions because they fall on the boundary between the Cretaceous (geological symbol K) and the Tertiary periods.

The Spanish conquistadors toppled the Inca Empire in the 16th century in their quest for silver and gold. They returned to Europe with a different sort of earthly nugget dug from the elaborate terraces sculpted into the sides of the Andes—the potato.

Potatoes have since spread to nearly 150 countries around the world; hundreds of millions of tons are grown annually, and the potato has become a staple in the world’s diet.
