...this energy than any man has ever devised. Ordinary cornstalks, ground to powder, can be used as a furnace fuel, like powdered coal. The Cabot researchers will try to develop bigger, more vigorous and faster-growing trees by artificial pollination and juggling of chromosomes (heredity elements in the germ cells). After 50 years the fund, if any of it is left, may be used for any purpose Harvard designates...
Author Kennedy's most skillfully constructed novel, Together and Apart attempts no diagnostic moralizing, leaves the reader to decide whether the Cannings' divorce scars were tokens of a constitutional middle-class weakness or a virulent old germ to which all flesh is heir...
...also explain inheritance of germ cells through the genes, units supposed also to be giant molecules. "In any case," said Dr. Stanley last week, "it now appears possible to list protein molecules along with living organisms such as bacteria, fungi and protozoa as infectious, disease-producing agents...
...This lasts for only some .00001 sec., but large protein molecules may be broken up, carbon dioxide and hydrogen given off, and water molecules in the cell oxidized to hydrogen peroxide. The cell may then sicken and die. If it is a cell in the reproductive germ plasm, a mutation or hereditary change may occur...
...extremes of temperature produce such mutations as abnormal eyes, queer-shaped wings and bald thoraxes in Drosophila melanogaster, the little fruit fly made famous by the genetic researches of Thomas Hunt Morgan. Many a geneticist suspects that the impacts of cosmic rays also start mutations working in the germ plasm. When the National Geographic Society's balloon Explorer II made its record-breaking flight into the upper air last year, Dr. Victor Jollos of the University of Wisconsin sent jars of fruit flies up with it, outside the gondola. The insects died of cold, but offspring hatched from eggs...
