...found to be caused by an excess of the potent hormone aldosterone (TIME, March 15, 1963), produced by the adrenal glands, which bestride the kidneys. If either gland develops a tumor, it is likely to churn out aldosterone too generously. The victim of this "primary aldosteronism" has too little potassium in his system and usually too much sodium, an imbalance that leaves him prey to intermittent paralysis, uremia-and high blood pressure...
...taken of a comet. Because of its close brush with the sun, Ikeya-Seki heated to an intensity that was easily recorded in detail by spectrographs, which gave scientists their strongest evidence so far of comet ingredients. Preliminary readings have already detected sodium, ionized calcium, iron, nickel, copper and potassium. Last week James Westfall, a young Caltech scientist, reported that his infrared observations of Ikeya-Seki were probably the first ever made of a comet. He is certain that the infrared emissions came from the comet itself and were not reflected sunlight. Analysis of this data should give scientists...
...first atomic bomb. Packed into 37 tubes of heat-resistant nickel alloy, the fuel is mixed with zirconium hydride, which acts as a moderator, slowing down the high-energy neutrons released by fissioning atoms of U 235. The heat of the reactor is carried away by a sodium-potassium alloy (NaK) that turns to liquid at 48°F. A beryllium reflector 2½ in. thick bounces escaping neutrons back into the uranium and keeps the reactor operating. When four openings in the reflector are uncovered, neutrons leak away, slowing or stopping the nuclear reaction...
...local beauty comes to Glas with a problem: her clergyman husband keeps insisting on his connubial rights, even though her heart belongs to another. That other, she intimates, is Glas. The doctor sees his duty. He must rescue the lady from rape. One afternoon. Glas slips a potassium cyanide pill into the clergyman's Vichy water. But the man with nerve enough to murder lacks the will to make off with the widow...
Getting ready for the try, Olivier boomed and bellowed at the rehearsal hall's rafters until he had amplified his "rib reserve." He soaked himself in potassium permanganate, but that failed to darken him sufficiently, so he settled in the end for coal-black grease paint. He tightened the spring in his stride, explaining, "Othello should walk like a soft black panther." He practiced the curiously accented, oddly stressed speech that evoked the way some Jamaicans and Africans gush English, managing thereby to convey the way the Moor spoke Italian...
