...ripe for all sorts of epidemics, and many varieties of pneumonia-causing bacteria were pullulating. So was Pfeiffer's bacillus, which had been mistakenly identified in 1892-93 as the cause of influenza and therefore named Hemophilus influenzae. There is no doubt that among the millions who fell prey to the virus, many were simultaneously attacked by this and other bacteria...
...most dramatic tests of all is for certain classes of virus that can be identified by their size and shape. It may take no more than three hours to prepare a specimen for Electron Microscopist Frederick Murphy to magnify up to 200,000 times. If he has caught his prey, its picture can be thrown onto a screen for a roomful of epidemiologists to see. Last week Dr. Murphy prepared such a specimen, and CDC Director David Sencer asked him: "Where is your picture?" A frustrated Murphy replied, "The picture is blank." Dr. Sencer then admitted: "We do not know...
Native-born peregrine falcons-not plentiful even when they were thriving -had not been seen in the skies over the Eastern U.S. for some 20 years. But now this fierce, graceful bird of prey, driven to the brink of extinction by DDT,* appears to be making a comeback. Ornithologist Tom Cade and his colleagues at Cornell University have succeeded in breeding peregrines in captivity and releasing them in the wild, where they can once again be seen soaring to great heights before diving on their prey at speeds of up to 200 m.p.h...
Achieving effective, environmentally acceptable methods of insect 'control will be expensive. The cost of producing even a few ounces of a pheromone runs into thousands of dollars; the expenses involved in sterilizing insects, identifying and isolating their hormones or finding parasites or pathogens that will prey upon them are equally high. The USDA alone, for example, will spend $48 million on insect control research this year. It will be money well spent, essential for keeping the insects at bay. Even as manufacturers begin producing some of the new biological controls, there are ominous signs that the ever adaptable insect...
...have rifled the diaries, journals, letters and reports of hundreds of participants and woven them into a totally absorbing, seamless war narrative that a novelist might envy. The voices range from Joseph Plumb Martin, an irrepressible private ("The grapeshot and langrage flew merrily") to General Washington, who was often prey to justifiable private gloom. (All might be well, he reflected in 1776, if his soldiers "would behave with tolerable resolution. But experience, to my extreme affliction, has convinced me that this is rather to be wished than expected...
