...Genetic Tool Kit The animals that aerated the Precambrian oceans could have resembled the wormlike something that left its meandering marks on the rock Erwin lugged back from Namibia. More advanced than a flatworm, which was not rigid enough to burrow through sand, this creature would have had a sturdy, fluid-filled body cavity. It would have had musculature capable of strong contractions. It probably had a heart, a well-defined head with an eye for sensing light and, last but not least, a gastrointestinal tract with an opening at each end. What kind of genetic machinery, Erwin wondered...
Harvard's unnecessarily irritating and competitive basic science courses can wear one down to a human parody that babbles biochemical formulas under the breath and has nightmares about flatworm phyla...
...client as a simple, small victim of big malign forces. To the six Cheyenne jurors, he characterized Penthouse Publisher Bob Guccione, 50, as an arrogant, unprincipled New Yorker, "the gentleman sitting over there in the velvet pants." When Guccione suggested that only people with the intelligence of a "flatworm" would think the disputed article was nonfiction, Spence, a University of Wyoming law graduate, began to refer to himself and fellow state residents as mere flatworms. He also listed 15 similarities between Pring and the protagonist of the article, which described how a baton-twirling Miss Wyoming used her sexual prowess...
Proud of It. The original choice of title was not made lightly, says Psychologist-Editor James McConnell, who heads the University of Michigan planarian (flatworm) research group, which publishes the W.R.D, "In psychological jargon," he explains, "those who experiment with rats are called 'rat runners,' and those who work with insects are called 'bug runners.' So we are 'worm runners'-and we're proud of it." Not enough scientists dig McConnell's logic-or humor. Some will not publish their work in a journal with so frivolous a name. Editors of other...
McConnell's piece summarizes some experiments with tiny primitive creatures called planarians, or flatworms, that he has published in his own journal, The Worm Runner's Guide, and elsewhere. His work, which has been confirmed by only some of the researchers who have tried to duplicate his expermiments, suggests that memory storage is in some way related to RNA, the gigantic molecule which is also involved in cell reproduction. He exploited the remarkable regenerative powers of the planarian to demonstrate that both halves of a bisected worm will contract in the presence of light if the worm has been...
