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...
...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...
...attack; in Copenhagen. "Economy plus function equals style," proclaimed Jacobsen, and he carried out his philosophy in stunning, spare buildings like those he designed for Oxford University's St. Catherine's College, completed in 1964. Jacobsen was equally well known for his interiors and furnishings. His famous "egg" and "ant" chairs earned him more money and acclaim than many architects received for entire buildings...
...very early "human" characteristics in the fetus, such as discernible brain waves at eight weeks. The findings of genetics, says Ramsey, suggest a much earlier date. Since the individual's unique genetic code, or genotype, is established at the moment of fertilization, the zygote itself-the fertilized egg-should be considered "human...
