Overgrown Atoms. Headliner of the convention was a round-faced, gum-chewing professor of Columbia University, Harold Clayton Urey, who won a Nobel Prize in 1934 for his spectrographic identification of deuterium, the doubleweight hydrogen atom which in combination with oxygen makes heavy water...
Heavyweight Detectives. Deuterium occurs in nature to the extent of one atom among 4,500 atoms of ordinary hydrogen. With modern apparatus if deuterium is present in quantities much greater than this proportion it can be detected. Thus if a man weighing 160 lb. drinks 20 drops of heavy water, the excess of deuterium will show in his urine. Biologists have been quick to see that, with two kinds of hydrogen atoms as distinct as red and green, a neat method was available for tracing the course of hydrogen-bearing compounds in body processes. Scientists in Germany have already found...
...biological label, heavy nitrogen promises Lo be even more important than heavy hydrogen, since nitrogen is the characteristic constituent of protein foods and their constituent amino acids. With Dr. Urey's heavy hydrogen, Biological Chemist Rudolph Schoenheimer...
...possibly millions of atoms. Although they cannot be seen under the microscope, the giant, complex molecules of proteins are among the most important targets of current research in biological chemistry. Until recent years not much was known about them except that they were very big; that they contained carbon, hydrogen. oxygen, nitrogen and sometimes sulphur and phosphorus; that in such animal processes as digestion they were broken down by protein-wreckers called enzymes and that they were composed of polypeptide chains which might, presumably, be contorted in any number of patterns...
...money for the company, the shares having been purchased from the Morrissey family, big stockholders. A similar deal last week was the marketing of 49,790 common shares of Harrisburg Steel Corp., a $2,000,000 maker of steel couplings and steel cylinders for gases like oxygen, acetylene, helium, hydrogen...
