...Women and Infants HIV Transmission Study (WITS) will examine the frequency of the Human Immunodeficiency Virus' transmission to fetus and its effect on the health of pregnant women and on the outcome of pregnancy, researchers said. The project will also chart the development of the disease in children...
About 500 pregnant women infected with the virus, 500 women who have tested positive for AIDS, 1500 pregnant uninfected women and 1500 women not known to be infected or pregnant will participate, according to the Harvard AIDS Institute newsletter...
...roommates who owned IBM computers were breathing a little easier last week after having uneasily anticipated the "Columbus Day Computer Virus" earlier this month. Hackers trembled at the prospect of a terminal illness which would wreak destruction upon term papers, lab data and anything else within the grasp of its electronic claws. A Macintosh user down the hall, immune to such plagues, offered some timely advice to stem the virus's spread...
...Politburo's tentative first step toward a softening of its policies was already more than many had anticipated.

...University of California at San Francisco, Bishop and Varmus resolved a spirited debate over oncogenes -- the genes, or units of heredity, that cause cancer. Researchers had previously theorized that cancer genes were separate entities, unrelated to the healthy functioning of a cell. But in studies of a cancer-causing virus in chickens, Bishop and Varmus found that oncogenes were normal genes, vital to cell growth and development, that had somehow gone awry -- probably as a result of mutations induced by carcinogens such as cigarette smoke and radiation. The team thus helped explain the role of genetic damage in cancer development...
