...appear as a familiar disk-if it could be seen through the murky Venusian clouds. But as it set, according to Stanford University Engineer and Physicist Von R. Eshleman, the disk would gradually diffuse itself around the entire horizon as a glowing band for the remainder of the night; sunlight is so bent, or refracted, by the dense atmosphere that it circles around to the dark side of the planet. At dawn, nearly two earth months later, the band would reassemble into a disk that would then slowly rise...
...surprising Houston team that everybody had overlooked, lost again to U.S.C. before finally posting a win over Wisconsin. Texas? Defeated by both U.S.C. and Texas Tech before venting its frustration on Oklahoma State. Miami? Another two-time loser-to Northwestern and Penn State-before seeing some sunlight against Tulane...
...vitamin D, which prevents rickets and is manufactured from the sun's rays by the body. As early man migrated out of the tropical sun-into the green jungle, north to less torrid zones-light skin thereupon conferred an advantage by admitting more vitamin D-produc-ing sunlight. And the lottery of evolution, patiently awaiting the appropriate mutation, then fixed this advantage into place. Thus, over the centuries, environmental factors were producing genetic changes...
...favorite rooms in the White House is a small private study a few steps down the hall from his ova! office. Heavy green curtains keep the sunlight out; the phone is muted to reduce noise.

In this womb with no view, he is at ease, cheerful, convinced that the country and the world are in tolerably good condition. His judgment is reinforced by the cables and memos that reach...
...layers of the skin involved in the sun-screening process are visible under a microscope. Below the skin's outermost horny layer, or stratum corneum (see diagram), lies a germinative layer where, on exposure to sunlight, the pigment-producing cells are stimulated to produce more melanin-and a suntan. The black races (Negro, Bushman-Hottentot and Australoid), with a more abundant supply of melanin, are in effect, perpetually tanned. Members of the white race are transparent-skinned in winter, when they must make the most of the limited ultraviolet avail able to synthesize vitamin D, but they take...
