...discarding a defective fetus." But Dr. Javert and colleagues at New York Hospital made microscopic examinations of 2,000 aborted fetuses, found no abnormality in 22%. In nearly all these cases he suspected some fault in the mother's physical or psychic setup (cases attributed to defective sperm were exceedingly rare). One astonishing statistic, suggesting factors introduced by marriage: while 10% of married women abort, only 1% of unmarried women do so. Also surprisingly uncommon (seven cases in 2,000) was injury as a cause of abortion. "Nearly all pregnant women sustain some type of external trauma...
...They are all following the same basic way of life. The adult consists of a "head" (scolex) that clings with hooks and suckers to the host's intestine. Below the head is a short neck that grows continually and differentiates into segments that become filled with eggs and sperm as they mature. The younger segments are chiefly male, and their sperm fertilizes eggs released by older segments farther downstream. A single worm can do the whole job and sometimes produces several billion eggs in its lifetime...
...such wondrous power and velocity in swimming as to defy all present pursuit from man," wrote Herman Melville of the finback whale. "This leviathan seems the banished and unconquerable Cain of his race." Captain Ahab and his men felt the same way, concentrated on other, slower beasts (notably the sperm whale, a species to which Moby Dick himself belonged). But today, with steam power and steel cables, the "unconquerable Cains" of the ocean, the fin and the blue whales,* are hunted vigorously-and among the most interested hunters is modern medicine...
...noted. Major Simons admits, of course, that cosmic rays kill tissue cells, but he does not think any part of an animal's body is seriously damaged by the loss of a few cells. Genetic damage is another matter. If a cosmic ray hits a reproductive cell (sperm or ovum), it can cause the birth of an imperfect individual. Major Simons cannot guarantee at present that all his high-flying mice and monkeys will have normal descendants...
...Trained as a lawyer, and a member of Parliament since 1935, Karamanlis early showed his mettle. When John Metaxas padlocked Parliament and declared himself dictator, he summoned Karamanlis and offered him a Cabinet post. Karamanlis looked Metaxas squarely in the eye and said: "Mister Premier, all dictatorships contain the sperm of death. They are doomed from the beginning, as will be yours. I think it might be better if you got some .older men to work with you." (Metaxas replied equably: "Young man, I think you're right...
