...might that happen? One of the most potent weapons produced by macrophages and other inflammatory cells are the so-called oxygen free radicals. These highly reactive molecules destroy just about anything that crosses their path - particularly DNA. A glancing blow that damages but doesn't destroy a cell could lead to a genetic mutation that allows it to keep on growing and dividing. The abnormal growth is still not a tumor, says Lisa Coussens, a cancer biologist at the Comprehensive Cancer Center at the University of California, San Francisco. But to the immune system, it looks very much like...
Saint Pierre, 39, has worked behind the scenes to facilitate some of the most illustrious unions in fashion: Christopher Bailey as creative director at Burberry (whose vision, she says, "was so much about this English attitude, the heather and the rain, and immediately we felt that he had the DNA in his blood"), Italo Zucchelli as the menswear design director at Calvin Klein, Christophe Lemaire as creative director for Lacoste. She also placed Narciso Rodriguez and Lanvin's Alber Elbaz in their first design-director positions...
...work has increased by an order of magnitude the avian DNA sequences available for genetic analysis, leading to new insights into avian genome evolution and population genetics,” Kirby said. “He will bring a valued modern perspective on avian biology to the Harvard faculty...
Concerns about American beef were assuaged last week when DNA tests proved that the American cow’s case of the disease originated in Canada...
...National Laboratory wasn't exactly a glamorous start. When Thundat arrived in 1991, fresh from postdoctoral training, he was put to work in a dank bomb shelter that had been converted into a lab. His task was to use an atomic force microscope to get a "snapshot" of the DNA molecule. All he seemed to be getting, though, was a headache. The microscope, which detects the con-tours of molecules by dragging a flexible sliver of coated silicon over them, was malfunctioning. After puzzling through his problem for months, Thundat realized one rainy day during a rare midday foray outdoors...
