...Dairy Queen." Our "gourmet" restaurants serve prepackaged, precooked Lobster Thermidor. Our cookbooks are compendiums of corporate-test-kitchen press releases. And the average sugar consumption in America--mostly of the refined, characterless variety--is one-third of a pound per day per American, which is more of this "poor nutrient," say the Hesses, than any society in history has ever consumed. And the reason? "Americans are starved for flavor...
...plastic bags and ice, the kidney was placed aboard a regularly scheduled Moscow-New York Aeroflot jet, while Shumakov sent word to U.S. doctors via a Soviet friend in New York that a kidney was on the way. Rushed by ambulance from the airport, the kidney was bathed in nutrient-rich fluid, then "typed" so that doctors could choose a recipient whose body tissue matched it. Out of the clinic's list of some 200 potential candidates, the doctors picked Puerto Rican-born Jose Serrano, a former construction worker with incurably diseased kidneys who was alive only because...
More encouraging results came from a second test, in which a sample of Martian soil that had been moistened with a nutrient broth showed a rapid release of carbon dioxide. The result might mean that some kind of microbe was metabolizing the food provided by Viking. But cautious scientists noted that certain peroxides in the soil might also have caused the reaction to occur...
...third experiment, the so-called "chicken-soup experiment," involves innoculating the soil with a complex nutrient broth that provides substrates for many biological activities. The soil is then incubated to encourage the growth of life...
...making his decisions, Martin is confronted by a complex series of deadlines. Some biologists are worried that the "chicken soup"-a nutrient-rich broth that will be used to moisten samples of Martian soil to determine if they contain organisms-will not keep long enough for all of the experiments scheduled. Even more vexing, Viking 2 is scheduled to arrive at Mars and go into orbit on Aug. 7. That will crowd the schedule of the Viking 1 lander, which will not begin to conduct its experiments until eight days after it lands. Each of the experiments requires an eleven...
