Chemical Hostility. Danielli and his collaborators, Joan Lorch and Kwang W. Jeon, worked with the amoeba's three major components: the nucleus (central control center), the cytoplasm (gel-like body matter) and the cell membrane (outer wall). In a typical experiment, they carefully removed the nucleus of one amoeba with a microprobe and sucked out most of the cell's cytoplasm with a tiny pipette. Then they inserted into the remaining cell membrane a nucleus and cytoplasm that had been similarly removed from other cells. In more than 70% of their attempts, the transplant produced a completely viable...
Surely but slowly, scientists are learning the structure of the basic molecules of life. They are gradually discovering how those molecules perform their exquisitely delicate and extraordinarily precise functions in all animals, from the amoeba to man. Despite their submicroscopic size, biologically active molecules are huge and complex-in atomic terms. Each one contains hundreds of thousands of atoms, arranged in submolecular groups-"building blocks" that are in turn arranged in definite numbers and patterns. Finding out how the building blocks are assembled in the major molecules has proved to be a challenging and time-consuming task...
...Amoeba with Food. The ruling Party of Republican Institutions (P.R.I.) also found itself under direct attack -something to which it is not accustomed...
...their eight children had telltale symptoms of hepatitis. A team of Air Force medics headed by Major Ralph D. Reynolds reports in the Archives of Internal Medicine that the virtually certain source was water leaking from the freeze balls. The water also carried whooping-cough germs, an amoeba and four species of bacteria, including at least three that cause dysentery. There was a strong suggestion of "fecal contamination...
...resources and colorful peoples. Walter, who conducted the first performances in the U.S. of the work of his countryman Heitor Villa-Lobos, based his own Third Symphony on native macumba (witchcraft) themes. Haroldo glows over the beauty of his native tourmalines, topazes, rubies and garnets, shapes each gem in amoeba forms that follow the structure of the stone. Roberto is infatuated with the dense Brazilian foliage, with its leaves that can be mottled, snowy, blue, asymmetrical, metallic or blood-veined, textured or wildly iridescent...
