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...
...awaited confirmation of a report from California, that an oil well in Madera County was yielding nearly pure helium. Scientists were skeptical for two reasons: 1) Exhaustive tests had convinced them that California gases are not helium-bearing. 2) When tested for lift, "helium" often turns out to be nitrogen or carbon dioxide...
...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...
...Declared they: "It is probably safe to say that it is more widely distributed in Nature than any known physiologically potent substance." Data so far accumulated indicates that pantothenic acid's molecule is composed of long chains of carbon, hydrogen and oxygen, that it contains no sulphur or nitrogen. The stuff is potent. A speck of Professor Williams' latest pantothenic acid, extracted from liver, speeds the growth of yeast in 250 gal. of liquid...
