...test site. "We saw the clouds go over all the time. Our children played outside. All the while, the Government kept saying that it wouldn't hurt us." But when the last of 102 mushroom clouds rose above the desert in 1962, Sheldon Nisson was dead from leukemia. His cancer, along with that of nine other victims, Federal District Court Judge Bruce Jenkins ruled last week, resulted from exposure to those drifting clouds of radioactive fallout. The judge found that area residents had not been given sufficient warning about the dangers of radiation and ordered the Government...
...cause of cancer. J. MacArthur Wright of St. George, Utah, an attorney who represented the victims, was pleased that Jenkins' decision establishes clear standards for litigating-or settling out of court-the remaining cases. "What I see as important," said Wright, "is that in all of the leukemia cases we tried, the court ruled for us. And in two of the tumor cases, he ruled for us. So in the case of leukemia, thyroid and breast cancers, the judge seems to be saying that there is enough evidence to show that radiation was responsible...
...without bone-marrow and gastrointestinal-tract damage. People living 5 to 7 miles from the accident could experience nausea and other symptoms but would be unlikely to die. Smaller amounts of radiation within a range of 60 miles from the site would result in significantly increased deaths from leukemia and other forms of cancer during the next 30 years. TIME...
...those "stem-defining" proteins are identified, they might be used as targets for drug therapies that could lead to better cancer treatments. Irv Weissman, the developmental biologist at Stanford University who first isolated the blood-forming stem cell, is working on pinpointing just such a suite of proteins for leukemia...
...thing, cancer stem cells seem to be extremely mobile, able to migrate easily from their birthplace to other parts of the body, where they can churn out more stem cells and launch new tumors. Eradicating those cells at their source might help control the spread of cancers like leukemia that flare from the blood to the bone marrow and other tissues. Blocking a stem cell's source of nutrients might be another effective strategy for drug development. Unlike normal stem cells, which tap into many different blood supplies for the oxygen and growth factors they need to survive, cancerous stem...
