...individual particles, not as a gas. Wearing a space suit, a scientist eventually will enter the vacuum and experiment with such puzzling problems as the behavior of lubricants in space, and the reaction of a model satellite, minus a protective cushion of air, to sunlight. X rays and ultraviolet rays beamed in through portholes in the chamber...
...anguished adolescent who feels disfigured by the pimples of acne, many doctors merely give a reassuring "You'll grow out of it," and let it go at that. At the other extreme, dermatologists have tried every conceivable remedy-vitamin A, vaccines, soaps, yeast, antiseptics, astringents, diets, hormones, ultraviolet and X rays, warnings against "picking."

Although it has not yet been decided exactly what scientific equipment will be placed inside the spheres (about twice the size of a basketball), it is sure to return valuable information about the upper atmosphere, cosmic rays, dust-type meteors, ultraviolet rays, and the precise shape of the Earth...
...years ago a young medievalist named Robert-Henri Bautier found occasion to examine some of Genealogist Courtois' documents more closely.

Last week, in the silent, august chamber of L'Academie des Inscriptions et Belles-Lettres, Scholar Bautier announced...
...billion tons of gas, mainly hydrogen, was expelled. The radiated ultraviolet light energy disrupted radio transmission for a time by affecting the ionosphere, which usually bounces the radio waves back to the earth. The cause of the flares is not fully known, Menzel said. They could be caused by shock waves from tremendous upsurges of gas in the sun's atmosphere or because of electrical and magnetic forces near an active sunspot group...
