...Trip to Mars (Universal). A stratospherical chapter of the 15-piece adventures of the fearless Flash, this is a Grade A cinemedition of the famed King Features strip. Chesty Flash (Larry Crabbe, onetime famed Olympic free-style swimmer) works desperately to save humanity on Earth from destruction by a nitrogen-destroying lamp erected on Mars...
...painful and sometimes fatal diver's affliction called "the bends" is caused by bubbles of nitrogen formed in the blood during a too quick ascent after a deep dive. Helium is so light that it tends to escape from the blood without forming bubbles of damaging size. Thus Nohl's suit considerably reduces the time necessary for a dive. But wishing to take no chances with his first 420-ft. try, he was brought up very slowly, in one hour and 45 minutes...
...virus, found to contain carbon, hydrogen, nitrogen and oxygen like thousands of organic compounds, could now be contemplated as a huge protein molecule -a "macro-molecule." Was it alive or not alive? No known living thing is crystalline in form. It would be fantastic to imagine a crystalline pig. Yet the virus showed the ability to reproduce itself in great quantities when stimulated by contact with a plant. Thus the Princeton chemist had discovered an apparent bridge between living and nonliving matter. This was a discovery of Nobel Prize calibre...
Columbia set out to discover what happens in the body to benzoic acid, a nitrogen compound used as a food preservative. In the test acid he substituted heavy nitrogen for ordinary nitrogen. Feeding it to laboratory animals, he found that about 70% of the acid passed through the walls of the intestine combined with glycine and was eliminated by the kidneys...
...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...
