Where do glaciers and icebergs get their beautiful blue color? This unique blue might be nature’s most brilliant, and the color arises in a very special way thanks to some surprising interactions between light and water molecules. Who knew physics could be so breathtaking?

Beavers have done more to shape North American landscapes than any animal beside humans. We don’t notice them much today because there aren’t many left, but before colonization, North America was home to hundreds of millions of these furry engineers. This week, we show you why Earth’s second largest rodent is more amazing than you ever knew, and why they’re the smartest thing in fur pants.
