...depends on how the radiation is delivered. Manufacturers of food and medical irradiation equipment say tests have shown that either of two technologies--ion-beam or gamma-ray--can render the spores inoperative by crippling their DNA...
Call it the reverse-O.J. effect. After Simpson's criminal trial, the Los Angeles police department's bungling of DNA evidence left jurors around the country skeptical of prosecutors. Add well-publicized problems with the FBI's labs and police-brutality scandals in New York City and Los Angeles, and "the law-enforcement community was tainted," says DeKalb County, Ga., district attorney J. Tom Morgan. But since Sept. 11, jurors have made a U turn. "There was a time when I'd ask people, 'If the government made it, it must be blank?' And in the past that blank...
...CIPRO and other antibiotics kill bacteria by interfering with an enzyme that the bugs need to create their DNA...
...WHERE DOES IT COME FROM? By looking at specific sections of the anthrax DNA, scientists can determine its strain and whether it has been genetically manipulated. Every sample from the recent cases tested so far comes from the same strain. It has not yet been matched with any of the known types of anthrax collected from naturally occurring outbreaks in animals...
...postdoctoral fellow at the University of California in San Francisco in the 1970s, and later at Genentech, Ullrich worked on cloning the gene for insulin. His research led to the development of the first commercial medical treatment, human insulin for diabetes, produced through recombinant dna technology. Since then Ullrich has been on a quest to battle cancer by concentrating on signal transduction, a means of communication between cells in the human body. From this work came the drug Herceptin, the first treatment to aim at the cells that cause breast cancer. Ullrich's approach is not to target the cancer...
