Water the Desert. Dr. Bonner does not think much of chemical synthesis of food or growing algae in nutrient solutions. Much more promising, he believes, is the irrigation of the world's deserts by freshened sea water. Such agriculture will be expensive, but it can be done if the need is great enough. Another potential resource is the ocean. Wild fish will never be a really large source of food, and the microscopic vegetation of the sea is too dilute for easy harvesting. But Dr. Bonner thinks that some algae-eating animal (a "sea-pig") may be domesticated...
Here, with Robbins now a member of the team, they explored the "roller tube" method of tissue culture. The simple idea was to place please of tissue in a test-tube with a special nutrient that would make the cells thrive. After observers had clearly established that the tissue cells were thriving on the nutrient tube, Robbins then injected a small amount of polio virus into the tube. To kill the tissue cells, the viruses would have to multiply in their experiments. Invariably, within one to five days the once-thriving tissue destroyed...
Meanwhile, there is the ever-present problem of finding nutrient soil in which the deb can flourish. The steady, promising young man of 30-mother's invariable choice for a son-in-law-seldom has time for the social round, so the deb for the most part must frolic with a younger, less stable type, whose main qualifications are strong legs for dancing and a talent for witty sophistication. Since such gay blades are not always reliable, the mothers at the Berkeley were busy last week grading them according to a private code. Those who rated NST (not safe...
Another method is tissue culture. Bits of cancer tissue are stuck to the side of a test tube. A nutrient solution (made of such unlikely ingredients as extract of human placentas) is added. The tube is sealed and put on a vertical merry-go-round in an incubator. As the merry-go-round revolves slowly, the solution washes over the cancer tissue, which grows vigorously just as if it were in a living body. Drugs can be tested against it simply by adding them to the solution...
...physiologists and bacteriologists assembled in secret laboratories under the Chemical Warfare Service. With them worked 3,800 Army & Navy men. In gleaming glassware grew the world's most vicious germs. A flask of cloudy liquid or a blob of nutrient jelly might contain the makings of a pandemic...
