...Outcries. The Price Commission can only recommend farm-price controls, but there are less drastic steps that it could take on its own, and members listed some in a private memo. For example, the commission could step up surveillance of supermarket profit margins, try harder to detect possible attempts to sell low-quality meat at premium prices, and insist that stores post more detailed price lists. As a last-ditch measure, the commission could clamp a temporary freeze on retail meat prices, hoping that store owners would then exert anti-inflationary pressure on their supply lines to the farmers...
ERTS's infra-red scanners can perform more subtle detective work, since every object, living or inanimate, emits or reflects the various wave lengths of infra-red light with a different intensity. Chlorophyll, for instance, a key chemical involved in the production of oxygen by green plants, has a very distinctive infra-red "fingerprint." Thus, by the color variations in photos, future ERTS satellites could quickly detect any large-and possibly dangerous -change in the chlorophyll content of ocean plankton, a principal source of the world's oxygen supply. By similar "fingerprinting," ERTS and its successors could warn...
...Epstein, the Cleveland toxicologist who first warned of the harmful effects of the detergent component nitrilotriacetic acid (NTA), contended that the beef was full of cancer-causing aflatoxins. "Don't know why the Swedes don't get rid of them," Epstein said. "They are so easy to detect-fluorescent...
...output of talk all over by making everyone think twice before speaking. It could also bring closer the Orwellian society of 1984. The remarkable but ominous device that might cause these changes is the P.S.E. (for Psychological Stress Evaluator) which, its inventors believe, can use voice recordings to detect lies without the cooperation or even the presence of the speaker...
...political meeting, or in the bedroom of a married-or unmarried couple. The tape is fed into a machine that measures muscular micro-tremors in the voice, faint quivers that come from the muscles in the voice box and cause slight changes in pitch. Changes are not detectable by ear, but they can be traced on a chart by a pen linked to the machine. It is the capacity to detect and reproduce these tremors-apparently produced by the freely undulating throat muscles of a relaxed speaker-that gives the P.S.E. its awesome powers. For the throat muscles...
