...began as an air raid-keening sirens, baleful searchlights, great gouts of tracer bullets spewing into the treacherous sky. But few bombs fell. Overhead, the British planes merely circled and then fled. What were those damned English...
...that of iodine. No fewer than 21 radioisotopes of this element can be prepared, and the medical profession has found ways to use six of them. Last week Ohio State University's Dr. William G. Myers reported that a seventh, I-125, shows promise as a convenient tracer to follow the metabolic pathways of ordinary iodine. But it has not yet been used in humans. An odd mother-daughter combination is ruthenium-rhodium 106. Long-lived ruthenium 106 gives birth to short-lived rhodium 106, which in turn gives off energetic beta rays. The pair had seemed promising...
...that the Norfolk would have run aground had it been where the Cubans said it was. The sub Sea Poacher reported that it might have been shot at on May 6 more than five miles off Cuba, but the shots were so wild that the sub crew thought the tracer bullets were signal flares. Even so. the U.S. made a formal protest to Havana...
...royal blood but also a very distant kinsman of Margaret. In a complex chart, Montague-Smith submitted proof that Tony is 22nd in descent from King Edward I's daughter Elizabeth* Moreover, a medieval lord of Harlech was a mutual ancestor of both Tony and Margaret. Exulted Tree Tracer Montague-Smith: "A thrilling discovery! The relationship between Princess Margaret and Mr. Armstrong-Jones really comes to this: they are twelfth cousins, twice removed...
Among the more limited specialties there are similar complaints of Balkanization. Pathologists, shut off in their laboratories studying specimens from patients they never see, resent the radiologists' monopoly of tracer studies done with radioactive isotopes. Plastic surgeons, whose practice is supposed to be little more than skin-deep, can hardly lift the scalpel without trespassing. Said one: "Every operation in my field crosses other specialties' borderlines." But it works both ways: the plastic men complain that ear-nose-throat specialists are too willing to bob noses...
