...brilliance of overhead lamps, a fox terrier listed in the laboratory records as Lazarus II lay last week in a gloomy old building on the University of California's campus. White-clad figures moved in & out of the glare, watching the creature they had asphyxiated with ether and nitrogen. Lazarus II's heart stopped beating and he no longer breathed. His shoe-button eyes were glazed. Lazarus II was dead...
This, according to the researchers, is probably what happens: The attacking alpha particle joins a boron atom to form a neutron (which flies off) and an unstable nitrogen atom which in a few seconds or minutes changes to a carbon atom with the release of a positron. Hence, just as the spontaneous radioactivity of radium turns it finally into lead, the end-product of boron's artificial radioactivity is carbon. Not only boron but magnesium and aluminum became radioactive under similar treatment...
Died. Fritz Haber, 65, Germany's foremost Wartime chemist, 1919 Nobel prizewinner, inventor of a process for the fixation of atmospheric nitrogen and of several poison gases, co-inventor of the Haber-Bosch synthetic ammonia process; in Basle, Switzerland...
...light of distant nebulae in their spectroscopes, astronomers got spectrum lines which they could assign to no known element. Accordingly they created by mutual consent a new element, called it "nebulium," and doubted that it existed. Years later they found "nebulium" to "be their familiar friends oxygen and nitrogen, ionized into unfamiliar atomic states...
Germany's Dr. H. O. Kneser has suggested that a large part of the absorption in air is due to collisions between oxygen molecules and water vapor molecules. Dr. Knudsen's experiments with air and its two major components, oxygen and nitrogen, weigh heavily in favor of this suggestion. There was no appreciable difference in the decay rates in moist nitrogen and dry nitrogen. But the decay rate in moist air was only one-fifth the rate in moist oxygen, and oxygen is one-fifth...
