...general technique of Russian research differs radically from that in the United States. For the Soviets, Doty said, comprehensive, systematic exploration largely supplants original thought. This determined, unromantic method has paid off in the study of plastics and molecular physics but the Russians lag behind the United States in chemistry and certain of the more abstract sciences...
...recipient, in his Rumford Medal Lecture, spoke on the evolution of the capacity of plants and animals to respond to light cues. Wald described the responses in terms of molecular or chemical mechanisms...
Richfield's big atomic bet is based on a chemical peculiarity: the molecular structure of Athabaska oil is such that, once thinned by heat, it flows indefinitely, whereas many heavy crudes thicken again in cooling. The spot picked by Richfield for its experiment has rich tar sand down to a depth of 1,000 ft. Then the underlying rock begins. If the A-bomb experiment works, the first small-scale (two-kiloton) detonation will be set off in the rock strata 1,200 ft. below the ground. Engineers expect that the bomb will create a huge cavity, and heat...
...weapons system has been more heavily guarded than the MOLE (Molecular Orbiting Low-Level Explorer). First hint of its existence came last spring when a Washington-datelined story in Electronic News reported that the Pentagon "is becoming heavily committed" to a radically new weapons system, added: "The MOLE should put an end to war. No location on earth will be secure from the MOLE." Later stories reported that 1) a special new agency (Subterranean Exploration Agency-SEA > had been set up to handle the new weapon and 2) the prime contract had been awarded to Accuracy Inc. of Waltham, Mass...
...automobile tire or piston wears out, so eventually must human organs, is only half true. In the youthful, still growing organism, cells divide rapidly, and all the components of the body (except nerve cells) are not only quickly added to, but also constantly replaced at the most intimate molecular level. This process does not stop with maturity; it goes on until death. But there is evidence that the rate of cell and tissue replacement slows down, until- perhaps at different times in dif ferent tissues - it is markedly less than the rate of natural death and destruction...
