Since Dr. Hardenberg started his work, bird accidents at Dutch airports have sharply decreased; but in-flight accidents have increased sharply and for no apparent reason. Most of them occur in spring or fall when birds are migrating, but some birds congregate dangerously at other times. Coping with migratory birds, says Hardenberg, calls for close cooperation between aviation experts and ornithologists. Pilots should get bird information along with weather forecasts, he says, and the movements of birds should be followed closely throughout Europe. Studies are now under way to see whether radar can watch for dangerous birds as it does...
...Harvard School of Public Health, Dr. Edward P. Radford Jr. and Dr. Vilma R. Hunt worked with polonium,* one of the rarest of the naturally occurring elements and until recently one of the hardest to detect. Many radioactive elements are found in tobacco leaves, as in all vegetation; they occur naturally and have nothing to do with man-made fallout, and they have been exonerated as causes of lung cancer. Polonium is different, the Harvard researchers reported in Science, because it vaporizes at a mere 500° C., far below the 800° temperature of a burning cigarette...
...word, just as they [social scientists] have already seen the need of expanding their conception of behavior to include talk (and the relatively low-level generalisations expressed in it), so they must now expand it still further to include the more abstract levels of theoretical behavior, wherever these occur in societies."

...able activities as weather control have taken risks with equally destructive energies, as when the early Project Cirrus seeded an Atlantic hurricane with dry ice, only to have it veer 120° to sideswipe a thinly populated stretch of Georgia coast. Yet if a large-scale disaster actually does occur in a Government program, the injured public has no assurance of compensation...
...decadence of the age, and a head full of apocalyptic hope, Brown keeps waiting for men from space to land on earth and solve all our problems with their miraculous source of power and wisdom. Through a mysterious, never elucidated grapevine, he gets word that the landing may soon occur in the tiny desert town of Twelvepalms, Arizona. Quitting his job and dodging inquisitive security men, he rushes off to meet THEM...
