...been a year of dramatic progress and turbulence for scientists experimenting for the first time outside the lab with genetically engineered bacteria. This past April, California scientists made the first outdoor tests of ice-minus, a bacterium genetically altered to retard frost formation on leaves. Only four months later, Montana State University Professor Gary Strobel created a national outcry when it became known that he had flouted strict federal regulations by failing to get approval before injecting elm trees with bacteria designed to combat Dutch elm disease. This week Clemson University scientists, mindful of public fears about the escape...
...goes according to plan, a team of Clemson researchers at the school's agricultural research station near Blackville, S.C., will sprinkle a murky white liquid teeming with billions of Pseudomonas fluorescens bacteria on winter wheat seeds during planting. It should be easy enough to tell whether the invisible microorganisms survive and spread: the Pseudomonas bacteria have been altered by genetic engineers to turn a brilliant shade of blue in the presence of a compound called X-Gal. Declares Benton Box, dean of Clemson's College of Forest and Recreation Resources: "The potential we now have for tracking a genetically altered...
...JERSEY'S garbage crisis reached crisis proportions this summer. Five times this summer, beaches had to be closed after garbage and ugly bacteria washed ashore. Governor Kean has declared a mandatory recycling plan. Most of the garbage landfills in the state are full and have closed. The remaining ones are reaching their capacity and have limited the types and quantity of garbage they'll take. Municipalities now are faced with the messy task of trying to redefine "trash" as opposed to "garbage" as opposed to "recyclable materials" under the new waste ordinances. Suburbia is in an uproar...
...water (Holly Farms) or broth (Perdue), along with seasonings and such preservatives as dextrose, sodium phosphate, malic or citric acid; many of the Farms products also contain vegetable or coconut oil. Though several samples from both processors were bloody, the meat is generally cooked until well done to kill bacteria...
...search for a new anticholesterol drug began in Japan. Akiro Endo, a scientist with the pharmaceutical firm Sankyo, wondered whether soil molds that kill cholesterol-containing bacteria might have evolved the ability to block cholesterol synthesis. In 1976, after testing 10,000 compounds, Endo found one that inhibited a key enzyme in the cholesterol-manufacturing process. Researchers at Merck soon discovered similar compounds, including lovastatin, but the finds would have remained research oddities without the Nobel-prizewinning work of UTHSCD's Joseph Goldstein and Michael Brown...
