Several groups of the eager investigators have been assigned the job of measuring the age of the lunar specimens by radioactive dating methods. By determining the ratio of radioactive elements (say, rubidium and uranium) in a moon sample to the amounts of their products of decay (strontium and lead, respectively), scientists can make a good approximation of its age. Thus, because the Apollo 11 samples will be taken from the surface of the Sea of Tranquillity, researchers may well be able to estimate the age of the moon's maria, or seas. This, in turn, might settle a longstanding controversy...

Designed to test the effects of weightlessness on living organisms, the temperature-controlled Biosatellite was stabilized in orbit to provide less than 1/100,000th of the earth's gravity for its tiny occupants. It also was equipped with a strontium 85 source that irradiated some of the organisms with gamma rays to determine whether the effects of radiation were different under weight less conditions...

...problem of war. For it is marvelous to talk about integration, but we've got to have a world in which to be integrated. It's marvelous to talk about drinking milk at an integrated lunch counter, but what will that milk mean if it has strontium 90 in it? I'm not going to sit silently by the wayside and see war being escalated in our world and never rise up to say a word about it. All I know is that the war in Viet Nam must be stopped. And I also know that there...

...newspaper since the test ban treaty was signed on Aug. 5, 1963, he should have known to be passe. Said King: "One cannot be just concerned with civil rights. What good does it do me to integrate a lunch counter if the milk I drink there is loaded with strontium...
