...open air one mile or less from the explosion's center. Cancer has been ten times more frequent in this group than among those who were inside shelters or situated farther from the explosion. Even among people exposed to a lesser degree of radiation, cancers of the thyroid, uterus and bone have developed in increasing numbers during the past decade. Numerous theories have been advanced over the years in an attempt to explain how radiation triggers cancer. The commission members hope that the cases of cancer in Hiroshima and Nagasaki will yield new clues...
Nature itself takes care of the worst genetic mistakes. One out of every 130 conceptions ends before the mother even realizes she is pregnant because the defective zygote, or fertilized egg, never attaches itself to the wall of the uterus. Fully 25% of all conceptions fail to reach an age at which they can survive outside the womb, and of these, at least a third have identifiable chromosomal abnormalities. Still, as many as five out of every 100 babies born have some genetic defect, and Nobel-Prizewinning Geneticist Joshua Lederberg believes the proportion would be even higher were...
Doctors also see possibilities in artificial inovulation, a procedure in which an egg cell is taken directly from the ovaries, fertilized in a test tube and then reimplanted in the uterus. By carefully scrutinizing the developing embryo in the test tube, doctors could spot serious genetic deficiencies and decide not to reimplant it, thus avoiding an abortion later on. If the embryo is normal, it could even be reimplanted in the womb of a donor mother and carried to term there, enabling the woman either unable or unwilling to go through pregnancy to have children that were genetically...
...possible, but probable. Dr. Landrum Shettles of Columbia University and Dr. Daniele Petrucci of Bologna, Italy, have shown that considerable growth is possible in test tubes. Shettles has kept fertilized ova growing for six days, the point at which they would normally attach themselves to the lining of the uterus. Petrucci kept a fertilized egg alive and growing for nearly two months...
INDEED, ONLY development of an "artificial womb" capable of supporting life stands in the way of routine ectogenesis, or gestation outside the uterus, and now even this problem may yield to solution. Scientists at the National Heart Institute have developed a chamber containing a synthetic amniotic fluid and an oxygenator for fetal blood, and have managed to keep lamb fetuses alive in it for periods exceeding two days. Once their device is perfected, the baby hatchery of Aldous Huxley's Brave New World will be a reality and life without birth a problem rather than a prophecy...
