DeBakey and his team actually performed operations on 69 victims. In some cases they reamed out carotid and other arteries leading to the brain, in others they bypassed a completely shut-down stretch of artery with a Dacron tube to carry blood from a lower stretch of healthy artery to a higher one. Among the 69 cases they found 13 for whom they could do nothing, and had five failures, but in 51 cases they reported success. In some instances this was as great as relief from a substantial degree of paralysis, or loss of speech, or partial blindness...
...only through the election of such liberals that the 86th Congress can achieve a constructive record. A preponderance of so-called "left-wing" Democrats in both Houses can break the old GOP-Southern Conservative coalition which has obstructed so much worthwhile legislation. A liberal majority would lower many of America's outrageous tariff barriers, would work for cheaper public power installations where private enterprise cannot do the job, and would advance more effective foreign aid programs, particularly in the field of economic aid for underdeveloped nations...
...ballistic trajectory above the atmosphere, with its engine cut off, the pilot will be weightless. He will then shift to a second stick that will give him better control in space-presumably by directional use of the steam jets. When he gets back to the lower atmosphere and conventional speeds, he will use the third stick, which operates in the conventional...
...drops back into the atmosphere, the pilot must match his speed to the density of the air. As the air grows thicker at lower altitudes, he must slow down to keep the heat of friction from softening his wings. If he comes too close to the danger point, he will veer upward into thinner air to let his plane cool off. Slowed down and cooled off, the X-15 can then glide to the ground, landing on a pair of nosewheels and two skids near the tail...
...Ability of students admitted to college is rising sharply. Stanford reports an upswing in aptitude test scores between 1951 and 1956 "so great that the lower half of the class entering in 1951 simply would not have been admitted in 1956." But college faculties, suggests Professor Wise, "have neither fully sensed this radical change nor taken adequate steps to provide challenge and stimulation for these new students." An alarming statistic: only about half of the students in the upper 20% of ability stays on to graduate...
