...four young Puerto Ricans, three of them drug addicts and the fourth a juvenile sex offender. Later, the two detectives assigned to the case earnestly insist that the boys were merely "questioned." The boys just as earnestly insist that they were punched, kicked in the groin and stifled with ammonia-soaked rags...
...radar. Over enemy infiltration routes, AC-130 Spectre gunships lay down a barrage of fire when the presence of troops is revealed by tiny air-dropped sensors no larger than a twig, including magnetic metal detectors and "people sniffers" that respond electronically to the smell of ammonia in urine...
...where Polaroid makes the filters necessary for terrain-following radar. This radar makes it possible for planes to fly in the dark close enough to the ground to detect the enemy" with infrared sensors, which respond to the warmth of their bodies, and with "people sniffers," which detect the ammonia in human perspiration. Without the terrain-following radar, the planes would risk flying into a mountainside, for they fly without lights to avoid providing a target for anti-aircraft fire. The A-armed with these devices, "makes ground movement after dark a nightmare," the plane's manufacturer boasts...
...scientists from the University of California at Berkeley pointed a radio telescope toward the center of the Milky Way galaxy, the island of stars in which the sun is located. To their great satisfaction, the big electronic ear picked up emissions that could only be given off by ammonia molecules (bombarded by radiation, molecules emit characteristic signals that can be used like fingerprints for identification). For the first time, complete, chemically stable molecules had been found in the swirling clouds of gases that occupy the enormous spaces between the stars...
Wollin and Ericson mixed the molecules of gases recently detected in the far reaches of space - ammonia, methanol, formaldehyde and formic acid - in various combinations. Then, keeping the gases completely free of water, the scientists exposed them to ultraviolet radiation and found that they combined to produce small quantities of some of the amino acids essential to life. Says Wollin: "Perhaps liquid ammonia, with its physical and chemical properties so similar to water, could serve as a solvent medium for waterless life...
