...childlike "signs," the brilliant and charming fantasies were gone. In their place were some small paintings on burlap, priced as high as $16,000, which consisted of little more than a few black forms swimming through solid color. There was a whirling constellation, a burning sun-shape inside an amoeba-like splash, a few nebulous and milky canvases that were each rather uncertainly called "Painting...
Feeding on Asteroids. As Cole envisions things, the human cells inside the unit would be both male and female, and they would multiply in the normal human way. But the unit itself would multiply asexually, like an amoeba. As its human population increased, its internal machine shops would turn out parts for a new unit, using ingested asteroid material. After 40 or 50 years a fresh unit of macrolife would separate from its parent and look for a place in the sunlight and an asteroid to feed...
Last week members of the American Institute of Biological Sciences opened a six-week meeting at the University of Colorado in Boulder to put some life into the study of living things by revising the high school curriculum from amoeba to zygote. With an initial $738,000 grant from the National Science Foundation, which has already spent more than $8,000,000 to upgrade high school physics, math and chemistry, the biologists have no illusions about producing high schools full of biology majors. But they do hope to increase the percentage considerably, and at the very least give every youngster...
...monkey' are defined by popular usage, man's ancestors were apes or mon keys (or successively both) . . . Man is in the fullest sense a part of nature and not apart from it. He is not figuratively but literally akin to every living thing, be it an amoeba, a tapeworm, a flea, a seaweed, an oak tree or a monkey." In a word, man lives in a world "in which he is not the darling of the gods." In other species, Simpson points out, uncontrolled evolution often leads to degeneration and usually to extinction. "But man is not just...
...chemistry of living things, no substances are more important than two that stand on the threshold between nonlife and life: ribonucleic acids (RNA) and deoxyribonucleic acids (DNA). Nothing can live without some kind of RNA, and the kind of RNA it produces, which determines whether it will become an amoeba or a mammoth, is in turn determined by its DNA, the template of heredity. Last week two U.S. physician-scientists were named winners of the 1959 Nobel Prize ($42,606) in medicine for having synthesized giant molecules...
