A piece of blue-green is seen against a light in a jade store and factory in Antigua, Guatemala, on May 22, 2002. Since the 18th century, collectors, geologists and archaeologists have sought the answer to a frustrating mystery: The ancient Olmecs fashioned statues out of this striking blue-green jade, but the stone itself was nowhere to be found in the Americas. Now scientists believe they have discovered the source -- a mother lode of jade in Guatemala.

A $100 bill on display as a money trader counts currency notes at a money exchange counter in Kuala Lumpur, Malaysia, on Nov. 22, 2004. After six decades in which the venerable greenback never changed its look, the U.S. currency has undergone a slew of make-overs. The most amazing is yet to come. A new security thread has been approved for the $100 bill, The Associated Press has learned. The new look is part of an effort to thwart counterfeiters armed with ever-more sophisticated computers, scanners and color copiers.

Greening Your Home
This undated file photo shows you can grow Key lime yourself -- not a difficult feat at all once you get a plant. Keep the tree in the sunniest window you have in winter, then move it outdoors to a sunny location in spring, once warm weather settles in. Move the plant back indoors in late summer. Expect your first harvest within a couple of years of planting the tree.
