...layer of ice had hardly been scratched in the second period before the mighty Big Red pounded three goals past Bill Fitzsimmons. Four minutes into the period, it was 6 to 3 and Harvard's chances were...
...process begins, they report, with the laying down of the familiar chalky and fatty material, largely cholesterol, inside the artery (see diagram). Then, by processes not yet understood, an "abscess" forms either within the artery's innermost layer (intima) or between the intima and the middle layer (media) of the three-ply artery wall. But this is no ordinary abscess, filled with pus. It is a special, possibly unique type, containing the debris of broken-down cells from the blood and the artery walls, a fatty paste, crystals of cholesterol, and calcium...
Tombaugh believes that the canals are faults or fractures, several miles wide, in the Martian crust. Their darkening and fading may be caused, he says, by the intermittent escape of hot gases that melt a thin layer of frost and vegetation. The oases where the faults intersect, he speculates, are probably impact craters where moisture gathers and promotes the growth of moss or lichenlike plants hardy enough to withstand the harsh Martian climate...
...dramatic demonstration of that strange phenomenon during the disastrous 1964 earthquake, says Columbia University Geologist Paul Kerr, whose investigation is described in the current issue of Scientific American. While probing beneath the battered sand, gravel and silt surface of Anchorage during the past two summers, Kerr studied an underlying layer of quick clay from 10 to 30 ft. thick. During the three minutes of the quake's violent up-and-down jolting, he concluded, some of the quick clay under Anchorage turned into liquid, triggering the damaging landslides that literally floated large sections of land to new locations...
...minimize damage from future Alaskan earthquakes, Army engineers are experimenting with a technique already used in Norway: forcing electrodes into the layer of clay and passing high-amperage currents between the electrodes to reorient the clay particles. Scientists are also conducting laboratory experiments that could some day put Anchorage on more solid ground. By pumping enough calcium salts into the clay to bind its particles together by electrolytic action, they hope to make the clay more viscous, resistant to shock and no longer thixotropic...
