...sampler of the Unpleasant: "Only 38% of nines and 49% of adults could time ten swings of a pendulum. Only 41% of 17s and 45% of adults knew the function of the placenta. Only 18% of 17s knew that nuclei are more dense than the rest of the atom; 93% thought that metal cans for food are made chiefly of tin." Among the Pleasant: "Ninety-two percent of nines and 98% of 13s know that a human baby comes from its mother's body. Seventy-eight percent of nines feel there must be a reason why a rubbed balloon...
Koshland's theory seems to provide the answer to the enigma. The reason that enzymes are so effective, he suggests, is that they hold a molecule's constituent atoms at the proper orientation for joining. By this "orbital steering," he explains, enzymes align the outermost electrons spinning around each atom so that they can readily be shared with other atoms. Such electron sharing is at the heart of all chemical reactions...

Soft Particles. For a while last week, medical circles were abuzz with a rumor that a U.S.-designed atom-powered pacemaker had also been implanted-in an American patient. That word proved to be premature; scientists at the National Heart and Lung Institute are still testing their prototypes in dogs...
...target was tiny-two-millionths of an ounce of a heavy, man-made isotope. The "bullets" were even smaller -atomic nuclei fired by an atom smasher. But the results of the experiment which were reported last week at a Washington meeting of the American Physical Society, made big news in the world of nuclear physics. A new chemical element, No. 105, has been created and identified...
