...partner in crime, Beatrice (Jessie Cohen) is equally confident and effective. Her acid attacks on Benedick melt into real compassion at the appropriate moment. Cohen's prim superciliousness perfectly captures her character...
THERE WOULD BE NO CHANGE IN THE TASTE OF THE daily bread, but the addition of folic acid, a valuable B vitamin, to flour, breads and baked goods, as recommended by an advisory panel of the U.S. Food and Drug Administration, could prevent a lot of misery. Just a smidgen of B, the group reports, could reduce the risk of neural-tube birth defects...
About 2,500 babies are born in the U.S. each year with most of the brain missing or the spinal column incompletely closed. Reflecting recent studies, many doctors advise that women planning pregnancy consume 0.4 mg of folic acid daily -- about double their average intake -- by eating more leafy green vegetables, citrus fruits, beans and fortified cereals or by taking vitamin pills. But many pregnancies are unplanned, and women do not realize that they are expecting until it is too late for supplements to do much good. Before approving the recommendation, the FDA must weigh whether the B-fortified food...
Hill helped clear up the confusion in the 1980s by carefully measuring the sulfur content of samples taken from the caverns. Her work proved that Carlsbad was carved not by carbonic acid but by sulfuric acid, produced by a reaction between oxygen dissolved in groundwater and hydrogen sulfide bubbling up from deep below the earth's surface. This highly toxic solution, which would have killed anyone present at the time, sculpted the many subterranean chambers at Carlsbad...
...biology played an important role in the rock-dissolving process. By poring over slices of limestone under microscopes, scientists found the fossil remains of primitive bacteria that had thrived in the once hostile environment. Using sulfur instead of sunlight as their source of energy, these organisms actually bolstered the acid's power to etch rock. Descendants of these strange microbes have recently been found and are being studied at Lechuguilla Cave, not far from Carlsbad...
