...families, one in North America and the other in New Zealand. In both cases, half of all adult family members had developed the disease. By comparing the DNA of the 40-odd family members who had tumors with the DNA of those who did not, the researchers hoped to detect a particular stretch of genes that could be linked to the disease. Such a unique pattern, called a genetic marker, would be a major step toward identifying the specific culprit gene. After discarding 344 potential markers, the scientists finally found one that fit the bill...
Troyan said that the best means by which to detect a growth is by the mammogram, a process which accurately identifies 85 to 90 percent of tumors, coupled with a self exam...
...culprit, test results show, is a tiny parasite with a big name: cryptosporidium. The oocysts (parasite versions of eggs) of this pesky protozoan can be removed only through filtration. Unlike bacteria, they are not readily killed by chlorine. Furthermore, the tests that water-purification plants routinely rely on to detect biological contaminants do not pick up the presence of cryptosporidium. What makes the parasite especially nasty, explains microbiologist Dean Cliver of the University of Wisconsin, Madison, is that the oocysts do not hatch in water -- in this case Lake Michigan water -- but remain dormant until they are swallowed by some...
...gunned down outside an abortion clinic in Florida, B.J. Isaacson-Jones was shaken -- but not surprised. At the St. Louis, Missouri, clinic where she is president, staff members always vary their routes home from work. Mail is opened only by employees trained by a bomb and arson squad to detect suspicious envelopes or packages. "Those of us providing abortion services feel very vulnerable," she says. Even more so since December 1991, when a man in a ski mask opened fire with a sawed-off shotgun at a clinic in Springfield, Missouri. Two people were wounded, including the clinic's office...
Certainly there is room for improvement in Clinton's plan, particularly in its credibility. Many detect a widening gap between Clinton's plan and his rhetoric. Ross Perot brought his traveling road show to a joint House and Senate panel and complained that Clinton's effort to call a new tax on Social Security benefits a spending cut was too sneaky by half. "Just call a spade a spade," said Perot. "It's not a savings, it's a tax." Similarly, the President denounced government waste last week, but he is not above rolling the pork barrel himself. He found...
