...cells and tissues that marks the growth of an embryo is one of nature's most exquisitely orchestrated movements. And, for vertebrates, the formation of the spinal cord and brain from a simple tube of cells is as crucial to life as it is beautiful to contemplate. But any defect in this neural tube, likely to appear early in development, can be devastating. Among the possible results: anencephaly, in which a baby is born minus most of its brain, and spina bifida...
...group of Harvard Medical School researchers is getting closer each month to discovering the genetic defect responsible for Huntington's disease...
...paper appearing today in an Oxford University journal, Assistant Professor of Neurology Marcy E. MacDonald and Professor of Genetics James F. Gusella reported that a DNA sequence within the general location of the Huntington's defect encodes an enzyme similar in structure to those involved in brain cell communication...
...Japanese, low-cost Asian copycats undercut prices and mowed down U.S. chipmakers with murderous effect: the semiconductor industry lost more than $4 billion and 25,000 jobs between 1983 and 1989. Dozens of firms abandoned the business. American companies also hurt their own cause with shoddy work and high defect rates. Written off by many experts, the semiconductor industry seemed destined for the same fate as steel, autos and televisions. Recalls Gordon Moore, chairman of Intel, the ranking U.S. chipmaker: "We were given up for dead...
...hypothesis advanced by some researchers isthat Huntington's disease is caused by a defect insome protein, present in cells throughout thebody, to which a certain class of neurons, whichdisappear during the course of a patient's life,are more sensitive...
