Professor James Ewing, foremost U. S. authority on tumors and an ultraconservative scientist, was made the subject of glaring U. S. headlines last week for a speech he made in Madrid. To the Inter national Cancer Congress there he merely said: "Sunlight is one of the greatest causes of cancer. Even trips to the beach often result in skin cancer." The headline transmutation of Professor Swing's qualified statement became positive: "SAYS NUDISM BREEDS CANCER...
...boiler, make steam to drive small engines. One of the most optimistic U. S. experimenters, Dr. Charles Greeley Abbott of Smithsonian Institution, has invented a "sun cooker" with which he roasts meat, bakes bread. Two years ago Germany's Dr. Bruno Lange discovered a way of converting sunlight into electric current a hundredfold more efficiently than had been done before (TIME, Feb. 1 6, 1931). But to run a 300,000-kilowatt power station would require a square mile of Dr. Lange's silver selenide cells...
...Observatory and J. C. Boyce of Massachusetts Institute of Technology. Since 1869 the light of the sun's spectacular corona, trapped in spectroscopes during the scant seconds of a total eclipse, has produced on the spectrogram five mysterious bright lines. Astronomers deduced that the corona, though mostly scattered sunlight, was partly self-luminous. What element made it so? Not knowing, they called it "coronium." As recently as last year, in a standard work on eclipses, "coronium" was treated with respect. The Menzel-Boyce report unmasks it as mostly oxygen in bizarre atomic metamorphoses. The normal oxygen atom has eight...
Vitamin D, the vitamin which controls the growth of bones, prevents rickets, is formed by sunlight acting on ergosterol, a vegetable substance. Chemical twin of ergosterol is cholesterol which is involved with the female sex hormone theelin. Sex hormones are intimately connected with growth, and so the "sterols" may be a foundation for all kinds of growth...
...synthesis of rubber." DuPrene, derived from chloroprene, is the synthetic rubber which du Pont is beginning to exploit. DuPrene, according to the company, has "approximately the same tensile strength as that of natural rubber, but it stretches further before breaking. It is less affected than is natural rubber by sunlight, oils, acids, heat. . . . DuPrene is considerably more expensive than natural rubber. . . . DuPrene tires will be little if any better than rubber tires, but DuPrene should be more suitable for the cover of a conveyor belt handling hot abrasive materials...
