But, thanks to Morgan's research in the early 20th century, and Kandel's and Brenner's work over the past 35 years, the fly Drosophila melanogaster, t

PRIZE WITH A PRICE: Science historian Peter Galison has taken some ribbing from his family since being named a MacArthur fellow. One could almost pity Peter Galison. A historian of science at Harvard University, Galison is one of seven members of the scientific community among the 23 recipients of this year's John D. and Catherine T. MacArthur Foundation Fellowships. The coveted five-year awards provide unrestricted support plus health insurance to talented individuals, with no reports or proj

WHAT FOLLOWS TAMOXIFEN? Warnings accompanied recent announcements from the University of Pittsburgh-based National Surgical Adjuvant Breast and Bowel Project and the National Cancer Institute in Bethesda, Md., that tamoxifen achieved a 45 percent reduction in the incidence of breast cancer compared to women who took a placebo in the Breast Cancer Prevention Trial. The 25-year-old drug still carries the risk of serious side effects for women over 50, officials said. But the overall results were
