...spawn, their eggs are collected and hatched in incubators. The fry are then raised until they are large enough to be kept in offshore pens for harvesting. On St. Croix, in the U.S. Virgin Islands, Lamont-Doherty scientists have successfully grown oysters, clams and scallops in artificial ponds, using nutrient-rich water piped in from the depths of the Caribbean...
...sterile drill to remove sections containing the bacteria. Their precautions produced an unexpected side effect. When they examined chips from the Ross Island core under a microscope, they found that microbes were moving around. "We may have heat-shocked them out of dormancy," says Cameron. Placed in a nutrient broth, the rod-shaped bacteria continued to move about. The club-shaped organisms proved even more responsive. On a culture plate, they reproduced and set up colonies that looked to Cameron like "inactive volcanoes...
...result of the experiment is good news to shipowners. For one thing, none of the nutrient ingredients are expensive. For another, the bacteria do their work so well that tanks would not have to be washed and scraped when ships put in for periodic repairs. This is especially important because the scrubbing is done with high-pressure hoses; the nozzles sometimes develop charges of static electricity that can ignite oil fumes lingering in the tanks. Moreover, Rosenberg believes that his bugs may turn even the ballast water into profit. He figures that after the bacteria have cleaned the tanks...
...acid, a component of milk necessary for growth and development. Because the black babies were apparently all orphaned and wards of the state, no consent was awarded in the babies' interests. The few white infants, children of interns, served as the "controls" receiving the normal diet of the essential nutrient...
...couple of weeks ago, a Medical School dean uncovered two studies in prominent medical publications in which a Texas research team had deprived infants of a fatty acid essential for growth and development. The team was aware that the deprivation of the nutrient could lead to irrevocable brain damage and would at least produce horrendous skin lesions. Black babies made up the overwhelming majority of the subjects used in those investigations...
