...Guinier, he would be driven from office. Yet, Lott will probably escape from this scandal unscathed, perhaps without even being forced to mouth an insincere apology. The Mississippi State Sovereignty Commission was disbanded in the 1970s. But the legacy of white supremacy continues to poison out society and to infect national politics...
...have involved the complicity of a company commander and ignorance of the problem several levels above that. Says Thompson: "At Fort Wood, it seems to be a horizontal problem, not a vertical one. Their approach seems to be 'throw the rotten apples out of the barrel before they infect the other apples.' " Thompson adds that commanders at Fort Leonard Wood had begun taking action to protect female recruits before the Aberdeen incident broke, but are now bearing down more firmly. "Female recruits presenting allegations of sexual harassment are now given a more attentive hearing," Thompson says, "and that...
...that time, scientists across the U.S. were excited about a possible breakthrough treatment: soluble CD4. They knew that HIV does not infect T cells at random. It must first attach itself to a particular protein, called CD4, on the T cells' surface. Perhaps, researchers reasoned, if they flooded the bloodstream with free-floating CD4 molecules, the molecules would act as decoys and prevent HIV from infecting the T cells. Preliminary tests on viral samples grown under laboratory conditions showed that soluble CD4 worked beautifully...
Then what happens? Cutting off treatment for patients taking the multidrug regimes would be a tragedy, and not just for the individual patients. Suddenly freed from that chemical barrage, the HIV in their bodies could easily become resistant to one or more drugs. If these patients infect anyone else before they die, an entirely new superstrain of HIV could be unleashed on the world--precipitating another and even more frightening public health crisis...
...Ashanthi DeSilva, are viruses, which by their nature invade cells and deposit their genetic material into the cell nucleus. Researchers have learned how to strip the viruses of their reproductive genes, insert into the viral DNA the beneficial gene they want to deliver, and then let the virus infect a patient's cells. The virus inserts its own now harmless genes, as well as the beneficial one, into the cellular DNA. If all goes well and the gene "expresses" itself, the cell begins producing the needed protein...
