...Human Genetics in Baltimore, is based on analysis of the "first polar body," a small packet of chromosomes sloughed off from the human egg during cell division. First the researchers remove several eggs from a woman's ovaries. Next the first polar body is detached, and a new genetic test called ! polymerase chain reaction is employed to analyze the chromosomes, which are complementary to those left in the egg's nucleus. Eggs that are not defective can then be selected and used in an increasingly common procedure known as in vitro fertilization. This involves placing the eggs in a soup...
...prefertilization testing is perfected, it could be a blessing for those ardently opposed to abortion. James Bopp Jr., general counsel for the National Right to Life Committee, says he can see nothing wrong with the test, since it does not involve "the taking of an innocent human life." Still, others have raised moral objections to the whole notion of "test-tube babies." The Roman Catholic Church and some conservative Protestant groups oppose IVF as a threat to the sanctity of human life...
Researchers caution that the test remains experimental and will not be widely available for several years. It has been tried on just five eggs from one woman, and none of the embryos developed. Verlinsky attributes this to IVF's failure rate. But his team must repeat the test on many women before convincing doctors that it is accurate and does not damage the ovum...

...Christopher Duvall, who was chief test engineer at Scott Aviation from 1983 until 1985, has told naval investigators the company tested the device in a way that would not properly measure its ability to protect the wearer. Since human tests of the device could not involve actual toxic gases, the Navy called for testing with salt or vegetable-oil aerosols. Duvall says the company knew the device could scrub out those relatively large particles but not the much smaller molecules of poisonous gases. Scott Aviation did not point this out to the Navy. According to Duvall, when more meaningful tests...
