Supersonic means faster than the speed of sound, which is about 760 miles per hour in air. That’s a speed limit that can be broken — by jets and bullets, for example, or by the space shuttle as it returns to Earth. Now, a scientist named Stephan Gekle has found that you can make air move faster than the speed of sound by doing a simple little trick: throw a rock in a pond. Gekle is a scientist at the University of Twente in the Netherlands who studies the physics of fluids. Physics is the study of forces and motion, and Geckle investigates how forces act on liquids, like water. In a rece...

Réunion is an island of surprises. It is French, but it’s nowhere near France — it’s off the east coast of southern Africa. After dark on this island, scientists use night-vision cameras to spy on the flowers. They want to learn more about pollination, which is how many plants reproduce. A plant becomes pollinated when pollen, which looks like powder, is moved from the male to the female part of the plant. And now for the strange part: While watching an orchid at night, these researchers recently filmed a new kind of cricket — one never before reported by scientists. Not only was th...
