Yucca Mountain Is Possibly More Seismically Active Than Once Believed, Geologists Discover

Submitted by Anonymous (not verified) on Thu, 1998-03-26 08:00
Recent geodetic measurements using Global Positioning System (GPS) satellites show that the Yucca Mountain area in southern Nevada is straining roughly 10 to 100 times faster than expected on the basis of the geologic history of the area. And for the moment at least, geologists are at a loss to explain the anomaly.

PASADENA—Wristwatch cellular phones and space probes the size of baseballs would certainly have some eager customers, but both are still the stuff of science fiction.

Nonetheless, physicists are making strides these days in the sort of miniaturization that could someday make tiny electromechanical devices a reality. One such milestone, the first nanometer-scale mechanical charge detector, is reported in the current issue of Nature.
