...that is more effective against salmonella. Irradiation could wipe out the bacteria, but it would be costly and consumer acceptance might be low, since many people mistakenly believe that zapping food with radiation makes it dangerous to eat. The visual inspections carried out routinely in the plants can weed out obviously diseased chickens, but the contamination is usually invisible. A panel of experts convened by the government may recommend soon that the Department of Agriculture develop better tests to detect salmonella...
...this year, the U.S. Department of Agriculture has approved nearly 100 test plantings of crops that have been genetically altered to give them traits such as pest resistance and tolerance to weed killers. More ambitious projects are envisioned, among them adding protein to staples like corn and changing the type of oil produced by soybeans. Pigs that grow faster and leaner and cows that manufacture medicine in their milk are other goals. Observes Arnold Foudin, a biotechnology specialist at the USDA: "Ideas that a short while ago might have been dismissed as harebrained Buck Rogers are now being taken quite...
...immigrants spent in the main building was short (three to five hours) but fateful. After depositing their baggage, they headed for the immense, vaulted Registry Room on the second floor. The stairway climb was called the "60-second physical" because nurses and doctors were perched at the top to weed out anyone who looked short of breath -- a possible sign of tuberculosis and heart disease. Then came more formal medical examinations and questions about the newcomers' politics. Anarchists and Bolsheviks were sent home. Others were singled out for further medical testing and possible expulsion...
...laugh off the idea of depravity emanating from their civic orchestra, ballet or Shakespeare theater. But in a battle conducted chiefly in the media, all it takes is a couple of controversial recipients to overshadow thousands of uncontested ones. And in the overheated climate of current debate, attempts to weed out controversial recipients can poison relations between the NEA and its beneficiaries. Last week the endowment reaffirmed a decision to strip grants from four performance artists, all of whom deal with sexual issues, after they had been chosen by fellow creators. NEA Chairman John Frohnmayer asserted that their work would...
...species of the family Formicidae make up from 10% to 15% of the world's animal biomass, the total weight of all fauna. They are the most dominant social insect in the world, found almost everywhere except in the polar regions. Ants turn more soil than earthworms; they prune, weed and police most of the earth's carrion. Among the most gregarious of creatures, they are equipped with a sophisticated chemical communications system. To appreciate the strength and speed of this pesky invertebrate, consider that a leaf cutter the size of a man could run repeated four-minute miles while...
