...Charles K. Kirby* of the University of Pennsylvania School of Medicine recently had an idea for making sure. He put Researcher Edward G. Thurston of Pennsylvania State College to work on a gadget. Result of their collaboration is a surgeon-alarm for gallstones: a tiny quartz crystal enclosed in silver at the end of a slender, hollow silver probe, and attached to an amplifier. The quartz acts like a phonograph pickup; when the probe touches a gallstone, it makes a ping or click-like the noise made when two small rocks are knocked together. The sound can be amplified enough...
When a miner breathes finely divided silica (quartz), the sharp microscopic particles, lodge in the little sacs at the ends of the air tubes in his lungs. The irritation forms scar tissue, whose stiffness keeps the sacs from collapsing, as they normally do, to expel air from the lungs. Breathing becomes harder & harder until the miner has to use all his strength merely to keep his blood oxygenated. Bacterial infections, including tuberculosis, often add to his misery...
Using a special quartz-rod light that he developed himself to make blood vessels transparent and three-dimensional under the microscope (TIME...
...device (e.g., to protect troops in such hazardous spots as blasted Hiroshima). The military now thinks it is all right for civilians to know about it. The instrument's chief working parts are a small chamber, a bronze wire (charged by a battery) and a fine, platinum-coated quartz fiber one-thirtieth the thickness of a human hair. When X rays or gamma rays enter the chamber, they leave a trail of ions which collect on the wire, neutralize its charge and move the quartz fiber...
There will be one door (a thick plate) and two windows, one of them set in the center of the door. Instead of glass, or the quartz used by William Beebe in his record-holding (3,028 ft.) bathysphere, the windows will be Plexiglas cones with the narrow ends pointing inward. Professor Piccard theorizes that the pressure will squash the elastic Plexiglas windows firmly into their sockets...
