Photo: Ori Fragman, Hebrew University Hordeum spontaneum, the plant studied for BARE-1 retroelements. With genome sequences arriving almost as regularly as the morning paper, the public's attention is focused on genes--new genes to protect crops against pests; rogue genes that make bacteria resistant to antibiotics; faulty genes that, if fixed, could cure diseases such as muscular dystrophy. What many people don't realize is that genes account for only part of an organism's DNA, and in many c
New Funds Possible For Embryo Research

In early October, preimplantation genetic diagnosis (PGD) made headlines when a Colorado couple used assisted reproductive technology (ART) to have a baby named Adam, whose umbilical cord stem cells could cure his six-year-old sister Molly's Fanconi anemia.1 When Adam Nash was a ball of blastomere cells, researchers at the Reproductive Genetics Institute at Illinois

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
