...engine. Presently, satisfied that he had broken the world's airplane altitude record and could get no higher, the lone pilot in the enclosed cockpit started down. Near exhaustion from the height, he began getting dizzy as the plane dived toward normal air, suddenly realized that not enough oxygen was flowing into his air-tight suit, that he was about to suffocate. Frantically he tried to open the zipper of his suit and the window of his plane. Failing, he used the last remnant of his strength to snatch a knife from the wall, slit open his helmet, gulp...
...write a vigorous rebuttal which Science published last week. Snapped Professor Lamson: "The human Ascaris [roundworm] is a parasitic animal living in the gut of man. It has no respiratory or circulatory system in any way related to that of an earthworm. It can live under anaerobic [without free oxygen] conditions. The earthworm is a free-living species inhabiting not man, but the ground. It feeds on substances in the soil rather than those of the human gut. It has no chitinous coat. It is dependent upon a circulatory system with not merely a single heart but five pairs...
...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 prove helpful for lung treatments. Actually, the triple molecule of ozone is a deadly poison...
...urea balance of the blood; without it man develops Addison's disease and dies. Last week the Mayo researchers announced isolation of a pure crystalline substance which seems to be a close cousin of cortin. The crystal molecule contains 21 atoms of carbon, 28 of hydrogen, five of oxygen. It seems to have the same effect on animals as impure concentrations of the natural hormone, although more of the crystals are required...
...paper the dairyman read that the Department of Commerce had just announced the discovery by a German of a new method of keeping milk for a long time without refrigeration. By sealing the containers with oxygen, a shipment of fresh milk from Rotterdam to Capetown and back was found after 60 days' travel to be "unchanged in taste, nourishing qualities or chemical consistency." Plain was the possibility of future importations of fresh milk from Europe or South America by this method...
