Although the meter contains a new type of photoelectric cell, of pure magnesium enclosed in corex glass, ultraviolet recorder: themselves are not especially new. But Professors Huxford & Cashman have started right out to get geographic comparisons. They find, for example, that Iowa and Nebraska are richer in sunburning sunlight than the Chicago region, that the uplands of South Dakota are richer still. They indicate their willingness to put their heads in a lion's mouth of uproarious dispute by comparing the healthfulness of Florida's sunshine with California...
Last week Washington's alert Science Service, browsing among the patent files, discovered that in his long search for a Unified Field Theory the great mathematician had not forgotten the uses of photoelectric cells. Patent No. 2,058,562, it appeared, had been issued to Dr. Albert Einstein and Gustav Bucky. Manhattan X-ray researcher, for an automatic device to prevent unskilled photographers from under-or over-exposing their plates.* A photoelectric cell attached to the camera measures the quantity of illumination available, adjusts a screen of varying transparency so that the proper amount of light is admitted...
...astronomers Albert E. Whitford and G. E. Kron of the University of Wisconsin announced satisfactory preliminary tests of a robot which, they hope, will relieve stargazers of this dull task. Light from the star is split by a reflecting .knife edge so that two beams fall on a photoelectric cell. If in the telescope the star image gets off the cross-wires, the two beams become unequal. The proper adjustment is then made by a mechanism in which the photoelectric current is amplified one quintillion times by a Zworykin electron multiplier...
...into Youth. The rule that what is young must irrevocably grow old is almost universal in Nature. But not quite. The bones of animals generate a young cell called an osteoblast, which becomes a middle-aged cell called an osteoclast, which becomes an aged cell called a fibroblast, which ultimately dies. Dr. Franklin C. McLean and his University of Chicago co-worker fed parathyroid extract to aged fibroblasts, turned them into baby osteoblasts...
...Radical Madrid Government, were Fascist Leaders José Antonio Primo de Rivera and his brother Miguel, wild-eyed sons of Spain's late Dictator. The Berlin Government was so concerned last week about José's welfare that a German officer was sent to his cell each night to get the Fascist leader's signature as proof that he had not been executed...
