...This is normal behavior on the women's tennis tour, where all the top players have a potent combination of talent, glamour and tennis-kid brattiness. Instead of keeping their rifts in the background, like most egomaniacal athletes, these women air their gripes and grievances on center court. It makes for great TV, which is one reason why, when the women's tour arrives in New York City this week for the U.S. Open, it will be the women's final, not the men's, that CBS airs in prime time...
What the Duke researchers showed is that one gene, called IGF2R, which helps brake growth, is normally imprinted in sheep, cows and mice but not in humans. Human clones would always inherit nonimprinted IGF2R genes, so there would be no chance of a mix-up and, at least in this respect, their growth would be normal. But what of the other 49 or so imprinted genes? No one knows what trouble they might cause. So the fact that humans have one less imprinted gene than mice, sheep or cows means that human cloning might be marginally easier, but not necessarily...
...challenging the simple plumbing model of heart disease were beginning to percolate through the medical establishment even as Ridker began his residency in 1984. The idea that heart attacks are caused by arteries gummed up with cholesterol was clearly inadequate; half of all heart attacks occurred in people with normal cholesterol levels...
...easy task, especially since doctors still don't fully understand how a normal cell becomes cancerous. But the challenge of stripping cancer down to its essential operations was what originally attracted Sidransky to the field when he was a medical resident at Baylor College of Medicine in Houston. "Of all the diseases confronting us in the early 1980s, cancer seemed the most interesting from an intellectual point of view," he says. "It seemed like something had to change...
What that "something" was became clear in the past decade as scientists began to see at the molecular level precisely what pushes a normal cell to become malignant. As more and more genetic mutations were linked to various types of cancers, researchers could see patterns of genetic changes that permit cells to grow into tumors. If doctors could identify the steps that a cell has to go through to become cancerous, Sidransky reasoned, they might be able to pick up a budding tumor's malignant imprints along the way--tracking cancer as it develops, from start to finish...
