...conflicting instructions, as, say, when a mother tells a child not to eat sweets, yet is constantly rewarding it with candy. But studies of identical twins and adopted children by Biochemist Seymour Kety strongly suggest a genetic base for schizophrenia. According to Kety, the flaw, contained in the cells' DNA, the master genetic molecules, may possibly be transmitted by viruses. In any case, the new pharmacological researchers no longer regard schizophrenia as a single ailment but, like cancer, as a collection of different malfunctions. In schizophrenia, the common denominator is the brain, and many scientists are convinced that a neurotransmitter...
...branched off on their separate paths much more recently. Their evidence is not ancient bones, but what the University of California's Vincent Sarich calls a "genetic clock." That timepiece is based on comparative studies, done since the early 1960s, of the blood proteins, immunology and DNA (the genetic molecule) of various mammals, including the primates. Out of this work scientists have been able to measure the degree of genetic kinship among different species. They have found, for example, that while the genes of horse and Homo sapiens differ by as much as 20%, those of chimps...
...race" for human insulin (Crimson, Nov. 14) with the statement that "This work, if successful, would provide an almost unlimited source of natural human insulin for diabetics at a low price, a very tangible medical benefit which would go far towards convincing the public of the benefits of recombinant DNA research...
...investigate the issue and lobby on behalf of the "community's best interests." The citizens' lobby this case is the Red Line Alert. The Red Line Alert is a coalition of the Neighborhood Ten, (who fought the Radcliffe gymnasium on Observatory Hill), and those who fought Harvard's recombinant DNA laboratories. The issues are different, but the gut reaction is the same: "There goes the neighborhood...
Harvard scientists, fearful of competition from universities in cities with less stringent DNA regulations, are pushing hard for enforcement of the latest guidelines. If Vellucci's past behavior is any clue, he will strenuously resist any attempts to change the ordinance. Krimsky says, "This whole issue of the ordinance could be a repeat of two years ago." That confrontation between Harvard and Cambridge left quite a few scars, and neither the University nor the city wants a repeat performance. But they may have no choice...
