...could be given by this route (he was the first to apply this technique to "preemies"). Then came detailed studies of the physiology of preemies (showing just what development handicaps they suffered), and other vital topics, such as the effects of a mother's illnesses on her unborn child, and what substances, from hormones to antibodies, pass through the placenta from mother to child...
...radio aerials to pick up the pulse beat. Coolheaded scientists at the Smithsonian Astrophysical Observatory in Cambridge, Mass, got on the long distance phone to alert amateur astronomers across the U.S., pulled the switch on Operation Moonwatch, the skygazing network the U.S. had set up to track its own unborn earth satellite. Other Smithsonian scientists sorted and fed into an electronic brain the fragmentary reports from moonwatchers, observatories and radio hams...
Almost everything has been tried for controlling the sex of unborn children, including the drinking by the woman (while an abbot prays) of thrice-blessed wine mixed with lion's blood by an alchemist. The New York Daily News in its salad days even had a sex-control editor. But nothing worked. Parents who wanted boys got girls, and vice versa...
...these days, science may come to the rescue. Geneticist Manuel Gordon of Michigan State University has succeeded in partially controlling the sex of unborn rabbits. His system depends on the fact that when a mammalian ovum is fertilized, the sex of the individual into which it will develop is determined by the sperm that does the fertilizing. Half the sperm cells have X chromosomes, which produce females. The other half have Y chromosomes, which produce males. So a way to start to control sex might be to separate the sperm cells into X and Y fractions before insemination...
...prenatal infections which sometimes result in the birth of defective children. As the world moves deeper into the atomic age, there is increasing danger to human embryos from radiation. Dr. Wolff's experiments may lead to discoveries which will minimize the effects of such radiation on generations yet unborn...
