Known & Unknown. Most cancer men, like London's famed Sir George Lenthal Cheatle, "have a completely open, not to say vacant mind" on the cause of cancer. But two known causes of cancer are now established: 1) organic compounds derived from coal tar, an industrial hazard setting up skin irritations frequently leading to cancer, 2) abnormal metabolism of body chemicals which produce sex hormones (TIME, Sept. 30). Both carcinogens have chemical characteristics in common. Memorial's laboratories have been working on these and a host of research projects on the influences of diet, heredity, radioactive elements on cancer...
...destroyers, looking like absurd little floating factories with their flat decks and four tall funnels, steamed up the harbor. They dropped their anchors, but only long enough for British sailors to go aboard. Then they weighed again, and made out to sea. There, under the Stars & Stripes, gob showed tar how to run the little knifelike craft...

Nieuwland & Neoprene. In 1900 the late Julius Arthur Nieuwland, Belgian-born chemist, Catholic priest and longtime teacher at the University of Notre Dame, made a poisonous black tar by treating acetylene with metallic chlorides.-At a scientific meeting in 1925 Nieuwland described one of his experiments producing acetylene rubber. A Du Pont chemist heard him, started his company on the trail. With Nieuwland's collaboration Du Pont workers made a good rubbery material first called DuPrene, now neoprene, which is highly resistant to oil. Its dozens of uses include hose linings, gaskets, conveyor belts, rubber gloves, printing plates, refrigerator...
