...emotional issues defined in liberal-conservative terms, Nixon has fallen on the liberal side. He was denouncing the John Birch Society and right-wing extremism in California before it became fashionable for Republicans to do so. He supported the 1964 and 1965 civil rights bills and the nuclear test-ban treaty although Goldwater opposed them...
...possibly harmful effects, Oyama has been raising mice and rats in 4-and 8½-ft. radius centrifuges that create artificial gravities from twice to 4.7 times normal and spin continuously except for brief intervals when they are shut down to clean cages and replenish food supplies. When the test animals are finally removed and returned to the normal gravity of earth, their experience is roughly equivalent to that of astronauts suddenly subjected to weightlessness or to a fraction of terrestrial gravity...
...Biologist William Platt have begun to use a new 26-ft.-radius centrifuge that can be supplied with food and cleansed of waste while it is running. On it, generations of rodents can be born and spend their entire lives under uninterrupted higher G. loads. From the responses of test animals-eventually including primates-Oyama hopes to predict the effects on astronauts of space trips that last for months and even years...
...years since Albert Einstein published his general theory of relativity, it has withstood determined attacks and ingenious experiments by other scientists anxious to test its validity. Although no experimental results have contradicted the theory, they have not been precise enough to rule out opposing theories that differ in small but significant details. Now a new technique has been used to check out Einstein: interplanetary radar. Preliminary radar tests also have failed to find a flaw in general relativity, a scientist from Massachusetts Institute of Technology's Lincoln Laboratory announced last week, and radar soon should provide results accurate enough...
Harvard came on the ice at full speed, forechecking ferociously and shooting with a mission: to test B.U.'s sophomore goalie, Mark Fennie. With each shot Fennie appeared closer to flunking. Pucks dribbled out of his glove into the crease and once he almost turned a shot from behind his own cage. He accidentally caught a slap shot by Chris Gurry between his legs, and twice benefited from the referees' quick whistles as the puck lay free in the crease...
