Mystery microbes of the sea
Biologists find archaea a true curiosity. They make up one of life’s three main branches. The two better known branches are bacteria and eukaryotes (u KARE ee oatz). That last branch includes animals, plants and fungi. But archaea have remained mysterious. Very little is known about them. In fact, their unique status wasn’t even recognized until relatively recently, in 1977.

Alien carp leap onto the scene
Last summer, Alison Coulter got a big surprise as she piloted a boat along the Wabash River in Indiana. Startled by her boat’s motor, a 60-centimeter (24-inch) carp leaped out of the river. In some cases, jumping Asian carp have broken a boater’s nose, jaw or arm.
