...terms of sheer frustration, the greatest sufferers have probably been astronomers using radio telescopes to scan the heavens. Stray terrestrial signals at frequencies similar to those being detected are a constant nuisance. It was not until the powerful radar at New York's Kennedy Airport was properly tuned that Bell Labs scientists in New Jersey were able to detect background radiation-mysterious microwave emissions from deep space, which some theorists think are the remnants of the "big bang" that created the universe...
...others are guided by the slight force of the earth's magnetic field. Some animals seem to depend upon old-fashioned topographic features, which they pick up with their own sonar. Eels, according to studies reported by Orr, have so keen a sense of smell that they could detect half a teaspoon of alcohol diluted in 42-mile-long Lake Constance...
...conduct in the past two months, especially in the Middle East. Moscow not only advanced its missiles in Egypt, but even after all of the fuss that created, it is still strengthening Nasser's air defenses in violation of the agreement, knowing full well that U.S. and Israeli intelligence detect every move. "This is deliberate?it is not clandestine," observes one Soviet expert in the U.S. Kremlin strategy raises all the old doubts about Moscow's intentions of abiding by any pact it enters...
...radioisotopes-forms of normally stable elements made radioactive in atom smashers. Radioisotopes have already become helpful in irradiating and arresting cancer. Lately, researchers have achieved even more significant results in cancer diagnosis. Because radioisotopes tend to concentrate in certain organs or diseased tissues, physicians have been able to detect tumors as much as six months before they appear on conventional X rays. Result: an important head start in the treatment of those that are malignant...
...abundance, and on France, where gangsters in "laboratories" around Marseille refine crude morphine into heroin, which is then smuggled into the U.S. The U.S., for example, has given Mexico $1,000,000 for the purchase of five helicopters, three light aircraft and other equipment to be used specifically to detect and catch violators. Dogs have been trained to sniff out marijuana. Since last October, the Mexican army has sought out and destroyed a total of 1,450 acres of poppy fields, and Mexican police have arrested 539 persons on drug-trafficking charges...
