Last week Dr. Ernest L. Wynder of Manhattan's Sloan-Kettering Institute and the University of Toronto's Dr. George Wright told fellow experts in Atlantic City that they had separated the tar (by machine-smoking tons of cigarettes) into acid, alkaline and neutral portions. These were subdivided again until the researchers found the active cancer-causing fraction. It proved to be in the neutral portion. Isolated and applied to mice in the laboratory, it produced many cancers. Although it constitutes only 1½% of the tar, the dangerous material contains many different chemical compounds, including a number...
...three-stage rocket 72 ft. long and 45 in. in maximum diameter. It will have no fins, but will depend for steering on its movable rocket motor and an array of small gas-jets. The tanks holding the propellants (liquid oxygen and gasoline for the first stage, nitric acid and dimethyl-hydrazine for the second) will be thin-walled to save weight, and will have little strength when empty. When they are full and highly pressurized with helium, they will become as rigid as auto tires and strong enough to serve as the structure of the rocket, which will have...
...weeks ago a thug hurled acid into the face of labor columnist Victor Riesel. The attack came only hours after Riesel's radio attack both of those racketeers who are attempting to gain control of labor unions, and of William DeKoning's domination of the Operating Engineers Union. The incident was described by the U.S. Attorney investigating racketeering in New York industry as "a black effort to intimidate witnesses." Governor Harriman decried the attempt to limit "freedom of speech," and Mayor Wagner called it "shame." The Operating Engineers Union agreed and added another thousand dollars to the growing reward...
...Baltimore, Dr. Cornelius P. Rhoads (TIME, June 27, 1949), director of the Sloan-Kettering Institute for Cancer Research, told how five years ago chemical research was directed into all kinds of areas-hormones, alkylating agents. Today, cancer chemists are concentrating on nucleic acid, which all cells need in order to live. If the cancer cells' supply of nucleic acid can be poisoned, the cells will...
...Dallas this week, an encouraging advance on the drug front was jointly announced by Sloan-Kettering, the Mellon Institute and Parke, Davis & Co. Their newest drug: "D.O.N." (for 6-diazo-s-oxo-l-norleucine), which effectively inhibits the formation of nucleic acid in mouse cancer cells, but causes negligible harm to healthy cells...
