...Geological Survey's lab at Menlo Park, a fired-up corps of young scientists is "bugging" central California's creaking faults with ultrasensitive new instruments. The lab has already set up more than 100 seismic stations, one-eighth of the world's total, to detect ever smaller earth tremors...
...Cincinnati, where a "continuous program to detect health hazards and sanitary defects . . . does not exist," and where infectious hepatitis, traced to the city's water supply, broke out in a new federal housing project...
...rapid spread of the blight caught the Government by surprise, partly because federal crop checkers found it hard to detect: healthy-looking stalks and leaves often concealed young ears that were rotting. As late as Aug. 4, federal crop forecasters were predicting a 1970 crop of 4.7 billion bushels, up 3% from last year. Last week Agriculture Department experts unofficially lowered that estimate by 10%, but plant pathologists elsewhere fear that the crop loss may run higher. Preliminary field reports indicated that 30% to 40% losses are likely in the Southeast, and that the yield in Illinois...
Since World War II, there has been an intensive effort to produce better infra-red detectors for the military. In Viet Nam, for instance, such devices have often been used to detect Communist troops in even the most densely foliated jungle. Other applications include heat-seeking missiles and spy-in-the-sky satellites. One of the leaders in the field, the Barnes Engineering Co. of Stamford, Conn., has developed detectors that can "see" the dark part of a crescent moon from a quarter-million miles away...
...promising use of thermography is in medicine. By spotting unusual temperature changes on the skin, doctors have been able to locate tumors, detect symptoms foreshadowing strokes, explore the extent of arthritic inflammation, gauge the severity of burns. If human skin is too warm, it may well mean increased metabolic activity and blood temperature underneath it, one of the signs of a malignancy. Cold skin may indicate dead tissue, as in severe burns, or reduced blood circulation, a clue to circulatory blockages...
