Research into cancer leads workers into many byways, occasionally into danger. In September, Biochemist Herbert Winegard began to study a substance called ergo-thioneine, a sulphur compound found in abnormal amounts in the urine of cancer patients; it may, chemists think, affect the growth of cancer. In order to make the compound artificially, Winegard had to work with an unstable chemical compound called diazomethane; it is a deadly, odorless yellow gas that can be inhaled without giving a warning sensation of choking. No antidote is known. On Thanksgiving Day he finished his first pilot synthesis at Philadelphia's Lankenau...
...headquarters were in a mud hut within a mud-walled compound. Outside the door a soldier hunched over a twig fire, drying his cotton shoes. Inside the hut at a table, the commander of Li's Eighth Army bent over a map. Two candles stuck in their own wax at the corners of the table were the only light. Li waved us to seats around the table and called for food...
...feet and leveled off to drop our 11,000-lb. cargo of rice. Six soldiers, moving stiffly in heavily padded khaki uniforms, wrestled the 50-lb. rice bags to the open hatch, tumbled them out and watched them land in tiny puffs of dust in a walled compound near the field...
...years U.S. millers have been using in their flour a compound called nitrogen trichloride. It bleaches wheat flour and saves months in the aging process (hence the trade name: Agene). It is now used in 80% of U.S. white flour. Sir Edward Mellanby of Britain's Medical Research Council fed a concentrated diet of highly Agenized bread to dogs he was using in an experiment on nutrition, published the frightening results in the British Medical Journal two years ago. The flour had caused "running fits"; most of the dogs that did not recover in 30 minutes died...
...ller was busy in a laboratory in Basel, looking for a drug to protect plants against insects. Trying one combination of chemicals after another, he finally found one that killed flies. He took some of the stuff home, and discovered that it killed mosquitoes too. Dr. Mller's compound was dichloro-diphenyl-trichloroethane...
