Besides the possible black hole in Cygnus, one appears to be part of another double-star system in the constellation Scorpius (the Scorpion). Three more may have been detected, each at the heart of a globular cluster of stars in the halo of the earth's Milky Way galaxy. In the inner regions of these clusters, which contain tens of thousands of individual stars, some of the stars are revolving with wobbly motions, as if disturbed by a center of enormous gravity. Herbert Gursky and Andrea Dupree of the Harvard-Smithsonian Center for Astrophysics believe that these stars "may well...
...their glazing techniques. David Pribnow characteristically uses matte glazes of different colored slips (liquid clays), which he paints on meticulously in geometrical patterns. Along with the slip method he uses salt glazing, throwing salt into the kiln at a critical moment, producing glassy, speckled surfaces. The shapes are globular and difficult to throw; the decorations rigidly geometrical. The result is the antithesis of accident--he inspires admiration, not empathy...
...that transformation takes place in man has not yet been positively determined, but it can be assumed that the human body contains an equivalent of the bursa.) B-cells are called the agents of humoral immunity because they synthesize antibodies that circulate freely in the blood. The antibodies, actually globular proteins, help the body resist disease-causing organisms. Both the B-cells and T-cells reside primarily in the body's lymphoid tissues, which are found under the arms, in the groin, behind the ear, in the abdominal cavity and other locations. From these tissues, the cells recirculate through...
Died. Harlow Shapley, 86, Harvard astronomer who proved that the earth and its solar system lay at the fringes rather than the center of the Milky Way; after a long illness; in Boulder, Colo. Shapley's study of globular star clusters and the changing luminosity of variable stars led to new means of measuring the vast distances across space and helped to disprove the belief that the earth's sun stood at the center of the universe. During the '40s and '50s he focused his gaze on earthly affairs, vehemently opposing McCarthyism, assaults on academic freedom...
Scientists suspected that DNA had a helper, a single-stranded chemical first cousin called ribonucleic acid (RNA). Most of the cell's RNA is found in ribosomes. These are globular bodies in the material outside the cell's nucleus that seem to be highly active centers of protein synthesis. But if this ribosomal RNA played a role in protein making, how did it obtain and execute the instructions from the master molecule DNA inside the nucleus...
