...definite benisons. Its thickness (about a foot, on the average) keeps noises out and it is a great weather insulator as well. But there are some drawbacks: once a thatched roof begins to deteriorate, birds find their way in and drive aviphobes crazy with their chirping. Some roofs have mice, too. Says Lord Compton: "Unfortunately, I'm allergic to cats, so all I can do is put out traps." A more spectacular peril is the danger from fire: a thatched roof, once touched off, explodes in flames...
Last summer Neurobiologist Nicholas Seeds of the University of Colorado Medical Center reported that he had not only been able to reassemble brain cells from mice, but that the reconstructed tissue continued to develop in a normal way. Now, in the Proceedings of the National Academy of Sciences, Seeds and a colleague, Albert E. Vatter, disclose that the cells in the test tube mature and form synapses, the vital cell-to-cell connections that transmit messages through the brain and the rest of the nervous system. The material also appears to develop the myelin "insulation" that covers part...
Harvard's Richard Sidman, who was the first to apply the reassembly technique to brain cells, is now experimenting with a special variety of laboratory-produced mice called "reelers." A genetically caused "wiring" defect in the cerebellum and cerebral cortex of the reelers' brains impairs their coordination so completely that they stagger like drunks whenever they try to walk. Remarkably, when the brain tissue was taken from fetuses that had just developed the defect, Sidman's cells reorganized themselves in the same curious pattern...
...researchers can ever learn to intercept the genetic command that orders brain cells to link up in a particular way, they may eventually be able to substitute commands of their own. That, in turn, might enable them some day to prevent wiring defects in mice and possibly even in higher mammals, including...
