...usually encountered near the constantly shifting west-to-east jet stream and near mountain ranges, where cold air frequently spills at great speed down the leeward slopes. Although the turbulence is obvious to any pilot caught in it, it cannot be seen by the human eye. Attempts to detect CAT with devices that bounce radar or laser beams against it have so far proved either impractical or inconclusive...

Kittenlike Proportions. After months of experimentation, a group led by North American Electronics Engineer Edward Flint devised a compact infrared sensor that can be mounted atop a plane. While scanning 45° to either side of the aircraft's flight path, the sensor can detect temperature variations as small as a fraction of a degree Fahrenheit in atmospheric carbon dioxide at a range of from 24 to 48 miles. These variations register on three side-by-side cockpit gauges that show the pilot whether a temperature gradient lies directly ahead or 45° to the left or right...

...instrumentation that has performed so effectively on earlier U.S. planetary probes. Unlike the last successful Venus shot-Mariner 2, which sailed within 21,600 miles of the planet in 1962 and sent back a surface temperature reading of 800° Fahrenheit, the newest Mariner may come close enough to detect a Venusian magnetic field-if it exists-and the equivalent of the earth's Van Allen radiation belts. It is also equipped to measure the density and temperature of the Venusian atmosphere, investigate the wake left by Venus as it plows through the solar wind, and provide new data...

...Rosen maintains that loss of hearing with aging results largely from clogging and hardening of the minute arteries nourishing the ear. If so, it may be possible to detect future victims of heart disease early in life by a simple, though sensitive, hearing test. Finns aged 10 to 29, on high-fat diets, suffer hearing loss earlier than young Yugoslavs or Cretans, on low-fat diets. To find out whether the pattern holds for the U.S., Dr. Rosen is studying New York City schoolchildren and their parents. If a simple hearing test does indeed give early warning of heart disease...

...groups of perspiring men. Urea, a component of perspiration, is attacked by bacteria on the skin and decomposed into odorless carbon dioxide and ammonia gas. Thus the air in the vicinity of a large group of men-especially in hot and humid climates-contains high concentrations of ammonia. To detect the ammonia, the E63 scoops up air, passes it over a wick saturated with hydrochloric acid and into a humidifying chamber. If the air contains any ammonia, a fog forms, changing the amount of light shining on a photoelectric cell and varying the amount of electric current that it produces...
