Most electronic noses have sensors that can detect the presence of a suspicious chemical by measuring the disturbance it causes in sound waves across a small quartz crystal. But just like a dog's nose, those electronic sniffers aren't able to determine whether the substance is cocaine or a compound with similarly sized molecules, such as caffeine. Stubbs addressed that problem by coating the sensor with an antibody that was similar in structure to cocaine. As a result, if cocaine were present in a room, it would attach to the antibody molecules and set off an electrical signal. Initial...
...change of scene, you can saunter along the lengthy peaks of the Sand Dunes near Stovepipe Wells, where desert winds have deposited grains of mountain quartz in a beach-like expanse that covers 15 sq. mi. Or you can visit Devil's Golf Course, where wind and rain have shaped the silt of ancient saltwater lakes into surreal crystallized salt pinnacles. And there's no place better to observe the tectonic forces that shaped Death Valley than at Badwater, the lowest place in the valley (and on the continent), where a salt-and-silt bog hundreds of feet below...
During World War II, Frondel worked with the Army Signal Corps to improve the quartz oscillating plates used in walkie-talkies. He was president of the Minerological Society of America in 1956, and spearheaded a project to revise a set of textbooks known as the “data volumes” used widely by minerologists...

Michiko and Yuko, who are slurping a 1 a.m. dinner of curry-flavored instant noodles on a street corner, are a couple of 17-year-olds who met on a weeklong pursuit of their favorite boy band, Glay clones called Due le Quartz. Parked nearby are their miniature suitcases, one a faux Burberry, the other girlishly pink with a strawberry pattern. Michiko has taken off from her suburban Tokyo home before, but this is a first for Yuko, who rode the rails in from northern Niigata prefecture. "My parents said no, so I just packed...
