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...
...normal genetic process in which DNA orders the production of "messenger" molecule RNA. Their enzyme permits RNA to manufacture the master molecule DNA. The Harvard team broke down rabbit hemoglobin and isolated its RNA. They then mixed this RNA with the Temin-Baltimore enzyme in a rich nutrient broth. They were thus able to trick the RNA into making the DNA from which it itself had been produced...
...alluring film, Red Top quickly emerges as a highlight of the rowing experience. The 16-mile trek out to the lighthouse and back, a typical early-morning fare in the workout menu, is somehow slightly sweetened by the thoughts of an afternoon round of croquet, lawn bowling or broth following the early evening row. Red Top puts back the old-styled gentlemanliness into rowing...
