...Scientific Approach. In Point Mugu, Calif., Chemist John Tabor stepped outside his laboratory door, spotted a 4-ft. rattlesnake poised to strike, reached for a carbon dioxide fire extinguisher, sprayed the snake into a frozen state, then carried it inside and killed...
...reproduces by splitting in two every twelve hours or so. A culture of algae is always at the height of its growing season. The whole plant is edible, and since it grows under water, it never suffers from wind, hail or frost. It can be fed with nutrients (chiefly carbon dioxide and combined nitrogen) by the simple method of dissolving them in water...
...algal culture has its drawbacks: it cannot be grown effectively in open ponds or tanks, where it quickly runs out of carbon dioxide or falls prey to microscopic predators. The best way to handle it is to circulate it rapidly through wide, flat tubes of thin plastic. The cells utilize sunlight most efficiently when they are exposed to its full intensity for only a fraction of a second at a time. So the flow of the culture must be turbulent, bringing the cells to the surface for a short time, then carrying them down into shaded depths. The "crop...
...booming chemical industry, Union Carbide and Carbon Corp. reported record sales in the first six months, and net income of $52,478,580, up from $46,440,458 last year. American Cyanamid Co.'s net income was up from $14,856,000 to $15,679,000; the six-month net of Mathieson Chemical Corp. was $8,828,633 v. $5,135,516 a year...
Organic chemistry, which has produced hundreds of thousands of compounds, is built on the fact that carbon atoms combine with one another to form rings and chains. Nitrogen atoms will do the same thing to a limited extent, but making nitrogen atoms link up with one another is extremely difficult on more than a laboratory scale. Hydrazine, which has two linked nitrogen atoms each attached to two hydrogen atoms, is the first of these linked "hydronitrogens" that has been produced outside the laboratory in appreciable quantities...
