...greatly overestimate the beneficial impact of it," concurs Michael Widner, an analyst at Stifel Nicolaus & Co. "I think that the people who were going to buy have already been lured in by the tax credit. As we extend it each additional month, you'll get a smaller and smaller effect." Also, while some experts applaud the idea of extending the credit beyond first-time buyers, they wonder if the $6,500 credit is large enough to make a serious dent. "The move-up buyer is buying a more expensive product and yet the amount of money being offered...
Often, moderate bias is just the result of caution, but the effect is to bolster centrist political positions - not least by implying that they are not political positions at all but occupy a happy medium between the nutjobs. Meanwhile, conservatives see moderate bias as liberal, and liberals see it as conservative - letting journalists conclude that it's not bias at all. (See TIME's special report "Obama After a Year: What's Changed, and What Hasn...
...Wake Forest University School of Medicine, witnessed out-of-control apoptosis in the brains of rats treated with drugs that mimicked the action of the general anesthetic ketamine. Starved of calcium, whole portions of the rats' brains died off - enough to cause significant cognitive impairment. In adult rats, the effect was much less severe. "There is something about the young brain that makes it exquisitely sensitive to the loss of calcium," says Turner, who was the first to propose that calcium depletion is a critical first step in drug-induced brain-cell injury...
...Some researchers, including Lisa Wise-Faberowski, an assistant professor of anesthesiology and pediatric cardiology at the University of Colorado, Denver, think the effect in humans won't be easy to show. At the ASA conference, Wise-Faberowski devoted her presentation to chiding researchers for worrying prematurely about "anesthesia-induced neurotoxicity," pointing out that it has been seen only in "cell cultures and lab animals." If anesthetics have always been neurotoxic, one slide in her presentation asked, "Why is it only an issue now?" She and others point out that non-human testing of anesthetic safety has an unreliable history...
...other scientists insist that melting, if it's occurring at all, has a relatively minor effect. "The fact that you have melting may mean air temperatures have increased, but it doesn't necessarily," says Philip Mote, who heads the Oregon Climate Change Research Institute at Oregon State University. "And in fact, the temperature on the summit of Kilimanjaro is essentially always below freezing, which makes it hard to accept warming as the reason [for glacier loss...
