ctograph's age using radiocarbon dating, the standard archaeological technique for more than a half-century. Rowe describes a new, highly sensitive dating method, called accelerator mass spectrometry, that requires only 0.05 milligrams of carbon (the weight of 50 specks of dust). That's much less than the several grams of carbon needed with radiocarbon dating.

The research included analyzing pictographs from numerous countries over a span of 15 years. It validates the method and allows rock painting to join bones, pottery and other artifacts that tell secrets of ancient societies, Rowe said. "Because of the prior lack of methods for dating rock art, archaeologists had almost completely ignored it before the 1990s," he explained. "But with the ability to obtain reliable radiocarbon dates on pictographs, archaeologists have now begun to incorporate rock art into a broader study that includes other cultural remains." - JS

Record long platinum nanowires: An advance toward better fuel cells
Nano Letters

Researchers from New York are reporting production of the longest platinum nanowires ever made an advance that they say could speed development of fuel cells for cars, trucks, and other everyday uses. The wires, 1/50,000 the width of a human hair, are thousands of times longer than any previously made, according to a report scheduled for the March 11 issue of ACS' monthly journal, Nano
