Earlier this week, Dr. Alvin F. Poussaint, associate dean of Student Affairs, exposed two University of Texas studies in which researchers deprived infants of a nutrient, aware that their action might cause emaciation and irrevocable brain damage...
...ecological equilibrium" is the accumulation of tons of guano (bird excrement) along the coast of Peru. Indeed, he noted, it is only when man collects the guano for fertilizer that the nitrogen-and phosphate-rich material is eventually returned to the "biological cycle in the form of plant nutrient." Guano is not the only example of nature's garbage. Peat, coal and even oil are all organic materials that have undergone only partial decomposition. Paradoxically, Dubos added, when man burns these fuels (and pollutes the atmosphere) he also helps complete nature's unfinished cycle, "because he thereby makes...
...specimen reaches a lab technician. Now Smith Kline and French Laboratories have devised a simple, self-contained test that physicians can perform in their own offices. The doctor takes a single smear from the patient's vaginal or anal area, places it in a tube enriched with a nutrient developed by the U.S. Center for Disease Control, and looks for a reaction in 24 to 48 hours. The new "Clinicult" test costs the doctor $2.30 and gives results as accurate as the older procedure...
...district engineers, aided by technicians from the University of Illinois, tested sludge in demonstration projects. The results were startling. The soupy product was easy to spray where needed with standard irrigation equipment and did not smell bad -both distinct advantages over animal manure. Better yet, used as a soil nutrient, it caused clay and even silicate sand to bloom. Still, nobody wanted sludge because of its despised origins. "We flew thousands of miles looking for people to take it," says Ben Sosewitz, general superintendent of the district. "Some people laughed at us. Though we had developed economical, beneficial methods...
...promotions. He is particularly incensed by what he contends is the lack of nourishment in most edibles, especially cereals, hawked to the pre-teen market. "The commercials advise your child to equate sugar with health and snacks with happiness," he complains. Choate's code would require that precise nutrient values be listed in food commercials for children; promotions based on an item's sugar content would have to warn viewers about the possibility of tooth cavities. The code would also ban more than four food ads an hour on children's programs and effectively bar all drug...
