On August 5, after a journey lasting more than 8 months, a carlike rover carefully settled down onto the surface of Mars. The vehicle is basically a science lab. Its mission: to search for evidence that the Red Planet might once have hosted life — even if the organisms were only one-celled microbes.
For roughly a century, George slowly explored his territory on a Galápagos island off of Ecuador’s west coast. The 200-pound guy ambled slowly.

More than a half-century ago, researchers at the Beltsville Agricultural Research Center outside Washington, D.C., engaged in some creative barnyard breeding. Their goal was the development of fatherless turkeys — hens whose eggs would hatch without being fertilized by a tom. Along the way, and quite by accident, an interim stage of this work resulted in a “churk” — the scientists’ term for a hybrid that had a chicken for a father and a turkey for a mother.
