...kentesis (pricking); it is performed by inserting a long needle through the mother's abdomen and drawing off a small sample of the amniotic fluid, the amber liquid in which the fetus floats. Physicians then separate the fetal skin cells from the fluid and place the cells in a nutrient bath where they continue to divide and grow. By examining the cells microscopically and analyzing them chemically, the doctors can identify nearly 70 different genetic disorders, most of them serious...
...appeared dead and bamboo had spread over the ground. A danger in this is that the invading bamboo species may be essentially worthless and very expensive to eradicate. Bamboo will retard the reestablishment of forest trees, at least for many decades. A further hazard is that large amounts of nutrient minerals previously tied up in forest vegetation may have been released and leached out of sprayed forests by the heavy tropical rains." The danger from this "nutrient dumping" is that on a large scale soil fertility would be reduced drastically...
...make such a desert bloom, the Columbia scientists are creating some upwelling of their own-in miniature. Dropping a 3½ plastic pipe off the northern coast of St. Croix, where the Caribbean slopes off very steeply, they are siphoning up nutrient-rich, cold (41° F.) sea water from a depth of half a mile and feeding it into small pools, each with a capacity of 16,000 gallons. Within ten days the pools teem with phytoplankton and become ideal breeding grounds for aquatic life. Last week the Columbia scientists "set" their first batch of young Chesapeake...
Lactose supplies about 40% of the caloric value of most milks. It is most abundant in human milk, about 7% by volume; the average dairy cow's milk contains 5%. Although lactose is a rich and valuable nutrient, it cannot be metabolized directly by the human system; it must first be broken down by an enzyme called lactase from its original complex sugar form (disaccharide) to two simple sugars, glucose and galactose. Normal babies secrete lactase in abundance and thus have no difficulty in digesting mothers' milk, cows' milk or comparable substitutes...
...economic success of hunter-gatherers has a "women's liberation angle to it." DeVore said. The women produce 80 per cent of the food supply by gathering greens and the nutrient-rich mungongo nut, while the men obtain the remaining 20 per cent by hunting, he explained...
