...culture of human brain cells. (Isoflurane had already been shown to cause cognitive impairment in rats.) He saw a vicious cycle of apoptosis and the accumulation of beta-amyloid protein - the sticky plaques that build up in Alzheimer's patients' brains - among the cells. But in this case, it may have been an excess of calcium that led to cell death. Xie and his colleagues have since found that the Alzheimer's drug memantine, which works by reducing calcium levels inside cells, can slow the rate of isoflurane-induced cell death. "That certainly suggests that Dr. Turner and we could...
...glaciers' surface, which would cause some melting. But most of the ice loss, he suggests, is due to sublimation - that is, ice turning directly into water vapor with no intermediate step. That tends to happen when temperatures are cold and the air is extremely dry, which is the case at Kilimanjaro's higher-than-19,000-ft. summit (it's the same reason ice cubes slowly wilt away in a frost-free freezer). That happens all the time, but if there's less precipitation to build the glaciers back up, which may be the case here, the result...
...this back-and-forth might suggest on first blush that the scientists are arguing over whether global warming is even happening. That would be a mistake. While he doesn't think Thompson's case is proven, Mote has no doubt that the climate is changing and that humans are largely responsible; he just doesn't think Kilimanjaro's glaciers are being melted out of existence...
...compelling argument, though one he has yet to sell to his moderate colleagues and, crucially, to the Obama Administration. Schumer tried to make his case for a public option at a White House meeting on Oct. 22. But by all accounts, Obama and his chief of staff, Rahm Emanuel, remained unconvinced, preferring to salvage the support of Snowe, who favors a public plan built around a trigger - meaning if competition is found sufficiently lacking in a state, a public plan might be created for that locality...
...Elections typically only resolve a conflict when the major parties to that conflict have accepted the balloting and its ground rules as the basis for a solution. And that was no more the case in Afghanistan today than it was in the U.S. in 1864, when a presidential election was held during the Civil War. Nobody imagined that the electoral contest between President Abraham Lincoln and General George B. McClellan was the country's primary political battle; nor was the contest between Karzai and Abdullah the key conflict in Afghanistan. Instead, Afghanistan is in the grip of a civil...
