...Paris' rue Chaptal, a cobblestone nook at the edge of Montmartre, is a quaint little Gothic chapel. Inside, carved cherubs and two seven-foot angels smile down from the black-raftered vault at a nightly round of vile murders, manglings, and assorted acts of torturing, fang-baring, acid-throwing...
...years U.S. chemical journals have discussed the violent and unpredictable explosive qualities of perchloric acid.* But 42-year-old Robert O'Connor did not read chemical journals. As secretary and manager of Los Angeles' O'Connor Electro-Plating Corp. he was chiefly concerned with sales and new business. He was delighted when a dark, bespectacled little man told him about a secret new electrolytic brew compounded of perchloric acid...
...conductor, had grown up into a cold and secretive youth who kept his room jammed with chemical equipment, showed little interest in anything else. They guessed that his knowledge of chemistry was self-taught-M.I.T. had no record of him. But he should have been familiar with perchloric acid's dangerous characteristics-he had worked as a chemist at Henry Kaiser's Fontana steel plant and for the Douglas Aircraft...
Harvard's Quentin M. Geiman and Ralph W. McKee said that they now know, pretty well, what foods the monkey parasite thrives on-para-aminobenzoic acid (a B complex vitamin), glycerol sodium acetate, certain other vitamins and amino acids. They have also been able to test the effect of antimalarial drugs...
...recent experiment was to put a "growth inhibitor" (iodoacetic acid) in the water. It did not kill the cells, but stopped their growth by breaking a necessary chain of chemical reactions. Then, one after another, Thimann added likely compounds, hoping to see growth start again. He found that malic acid (which is found in apples) would overbalance the evil influence of iodoacetic acid, allowing the cells to grow. This proved that malic acid was somehow involved in the chain of reactions which the inhibitor had broken...
