...normal process of sexual differentiation, Money explains, if the genes order the gonads to become testes and to produce androgen, the embryo develops as a boy; otherwise it becomes a girl. Androgen not only shapes the external genitals but also "programs" parts of the brain, so that some types of behavior may come more naturally to one sex than to the other. For instance, both men and women can mother children-the necessary circuits are there in every brain-but the "threshold" for releasing this behavior is higher in males than in females. The same phenomenon is demonstrated by laboratory...
...chemicals put in to improve their taste, the preservatives to increase their shelf life and the processing that may rob them of their nutrients. Some items pushed by the granddaddies of today's faddists have proved highly beneficial. They long ago touted wheat germ, the vitamin-rich embryo of the wheat kernel, and such health store staples as safflower oil, nuts and unsweetened juices...
...limited distribution may double the retail cost. A pound of Granola, a cereal containing oats, wheat germ and sunflower seeds, can run a customer as much as 89?, or just about twice the price of a box of "enriched" breakfast cereal. Fertilized eggs, which contain a tiny chick embryo, average 30? a dozen more than standard, unfertilized eggs. Yet demand for such products is so great that profits are almost always assured...
...Bold Ones will be getting bolder, mainly by knifing into such delicate surgical issues as embryo transplants and lobotomy. The lobotomy episode will also depict that rarity on TV medical shows: a crooked doctor. No new adventure hero, it seems, will be admitted to the schedule without an ethnic identity badge. ABC'S Kung Fu is a sort of Fugitive foo yung-a Chinese priest permanently on the lam in the American West of the 1870s, nonviolent but ready to zap troublemakers with the self-defense art of kung fu. The title character of NBC's Banacek...
...scanning electron microscope, he determined that the average thickness of the eggshells in the lower or older layers ranged from 1.7 to 2.6 mm., while the shells in the younger layers were only about half as thick. Such fragile eggs could easily become dehydrated and broken, killing the dinosaur embryo. Scientists now have evidence that DDT can interfere severely with the production of hormones involved in the making of eggshells, but such chemicals were obviously not around in the dinosaur's day. Erbea suggests that similar hormonal imbalances might have been caused by unusual stress. What stresses were there...
