...will probably contain some improvisation, but the format is not yet established, Warnick said, adding that it would be useless to create a "carbon copy" of the Proposition...
...suffer from heart and liver damage that produces a 30% mortality rate. She deals with lung damage from such new chemicals as tolylene diisocyanate, widely used in foam rubber products; nerve diseases caused by various new solvents used in the printing industry; damage to nerves and organs from carbon disulfide among workers in rayon textile plants. Muscle and Blood also explores continuing safety hazards in the mining and automobile industries, as well as the psychological stresses in automated assembly operations...
Great numbers of Americans are inhaling carbon monoxide, a notoriously poisonous gas, in quantities far above levels normally considered safe. That fact, reported in the A.M.A. Journal last week by a team of researchers from the Medical College of Wisconsin, is not surprising in itself. It has long been known that cigarette smokers, workers in certain industries and people in the dense traffic areas of major cities breathe in abnormally large amounts of carbon monoxide. But the Wisconsin study reveals that surprisingly many nonsmokers, office workers and residents of rural communities are also exposed to high concentrations...
...Carbon monoxide (CO) produces its poisonous effect by crowding out oxygen molecules that normally attach themselves, in the lungs, to the hemoglobin molecules in red blood cells. By a malign quirk of nature, CO has an affinity for hemoglobin more than 200 times as great as that of oxygen. Thus too much carbon monoxide starves the body of oxygen, causing illness and sometimes death-as in the case of the suicide who runs a hose from the engine exhaust to the inside of his car. But how many Americans are inhaling an excessive amount...
...test, a small sample of Martian soil will be partially submerged in a nutrient-rich solution (called "chicken soup" by the experimenters). If any Martian organisms grow in the broth and give off carbon dioxide or other common byproducts of respiration-like life processes, instruments will detect these chemicals. In another test, soil will be exposed to a nutrient containing radioactive carbon 14. If any microorganisms consume the nutrient and give off carbon-bearing gases as metabolic wastes, those wastes will be radioactively "tagged" and readily identified. Lastly, a Martian soil sample will be exposed to xenon "sunlight...
