Lost wallet? More cash means you're likelier to get it back

NEW YORK—People are more likely to return a lost wallet if it contains money—and the more cash, the better.

Ash species on brink of extinction

NEW YORK—Five prominent species of ash tree in the eastern U.S. have been driven to the brink of extinction from years of lethal attack by a beetle, a scientific group says.

Tens of millions of trees in the U.S. and Canada already have succumbed, and the toll eventually may reach more than eight billion, the International Union for Conservation of Nature said today.
