...Utrecht University, where much of the pioneer work on them was done. In 1928 a tall, dark young man named Fritz Warmolt Went, who began his botanical career at Utrecht under the tutelage of a distinguished father, got enough of one auxin in high concentration to measure its molecular weight. Three years later Kögl and his associates identified an auxin in urine, isolated it in pure form. This is called Auxin A. In 1934 the Utrecht researchers followed with Auxin B and heteroauxin. Heteroauxin has the astonishing effect of making roots sprout from the stem in shaggy masses...
...University of Wisconsin got $27,500 for a Svedberg ultracentrifuge, a device which analyzes molecular weights by whirling materials around at a centrifugal force 350,000 times the force of gravity...
Last week the Swedish Royal Academy of Science awarded its 1936 Nobel Prize for Chemistry to a profound student of molecular structure, Professor Peter Joseph Wilhelm Debye, 52, of Berlin's Kaiser Wilhelm Institute for Physics. The Prize for Physics was divided between a pioneer cosmic ray researcher, Professor Victor Franz Hess, 53, of Austria's Innsbruck University, and 31-year-old Professor Carl David Anderson of California Institute of Technology, discoverer of a fundamental particle of matter, the positive electron. Prizeman Debye will receive about $40,000, Prizemen Anderson & Hess each half that...
...whereas the batches of atoms created or transmuted by physicists cannot even be seen under the microscope, chemists now synthesize molecules after Nature's pattern in quantities that keep factories humming and salesmen humping. Molecules are groups of atoms which act as chemical units. The vast importance of molecular structure is well illustrated by the case of ozone, which is a modification of oxygen having three atoms in its molecule instead of the ordinary two. In the popular mind "ozone" has long been a synonym for pure and therefore beneficial air. Many a tuberculosis researcher has hoped it would...
...Separation of hemoglobin, blood's red coloring matter, from the blood serum would require 180 years by gravity sedimentation, but may be accomplished in six hours with DuPont's new Svedberg (1 electro-condenser, 2 atom gun, 3 molecular magnet, 4 centrifuge, 5 chemical reducer...
