Last week Professor Herbert Davenport Kay & associates of Toronto suggested in The Journal of Nutrition that beryllium, a metal related to calcium and now coming into industrial use (it strengthens and hardens aluminum alloys), may be an obscure cause of rickets. When the experimenters added as little as 2% of beryllium carbonate to the diet of rats, the rats grew humpbacked, wobbled as they walked, showed practically all the other signs of rickets. No amount of cod-liver oil, viosterol, ultraviolet light or sunlight improved their condition. Best deduction is that the beryllium combines with phosphorus, which is essential...
...Lathrop Parsons, 65, went the American Chemical Society's senior kudos, the Priestley Medal. He has been the Society's secretary for 25 years, its business manager since last year. His work in pure chemistry flowered 30 years ago when he was busily exposing the properties of beryllium. As chief chemist of the Bureau of Mines he was a leader in the chemical prosecution of the War. Since 1919 he has practiced in Washington as a consultant chemist...
Among those who have been bombarding atoms with alpha particles are Mme Curie's daughter, Irene Curie-Joliot, her husband F. Joliot, Dr. Chadwick and Professor Walter Bothe of Giessen, Germany. Professor Bothe, bombarding beryllium, decided he was creating an artificial super-gamma ray. Dr. Chadwick decided that a proton and an electron knocked loose by alpha particles might combine, without any electrical charge at all, in one unit to make a neutron. This self-contained unit might be the ultimate unit of magnetism, having within itself opposite poles...
Cosmic rays may be evidence of cosmic construction (Millikan theory) or cosmic disintegration (Jeans theory). They may be the neutrons which Dr. James Chadwick of Cambridge University found bombarded out of beryllium (TIME, March 7) and which Dr. H. C. Webster of the University of Bristol last week reported that he had knocked from boron and fluorine...
...noteworthy that neutrons have been recognized as coming from elements which are the lightest of their groups in the Periodic System. Beryllium is the lightest of the earth alkali group (beryllium, magnesium, calcium, strontium, barium, radium). Boron is lightest of the earth metals (boron, aluminum, scandium, yttrium, lanthanum, actinium). Fluorine is lightest of the halogens (fluorine, chlorine, bromine, iodine and, newly recognized, alabamine...
