...touted a cell phone (a gift, she beamed with an endearing mix of shyness and pride, from her North Korean boyfriend). Cockerell says that up to 50,000 personal cells are rumored to be in use in Pyongyang. There are three models - all Chinese brands - available in local shops and priced roughly between $210 to $280. Locals can use them to arrange meetings at Pyongyang's new and popular fried-chicken restaurant (the colloquial term for fried chicken there is kentucky, and a mixed platter is about $12.50 or the equivalent in euros, which is the preferred foreign currency...
...Cell phones? Pizza? "Kentucky" fried chicken? They even have a busy bowling alley or two, and we benefited from rolling BBC News in our hotel rooms. This was not the Pyongyang we'd come to expect. And yet such developments should not come as a shock, argued Cockerell over a microbrewed ale (70 cents) in Pyongyang's downtown Paradise Bar. "Foreign reporting on the D.P.R.K. is macro in scale - it's always, 'But aren't they testing nuclear weapons up there?' Subtle changes in the lives of Koreans don't fit the reporting paradigm; those changes are considered too trivial...
...role of calcium in the healthy brain is critical, particularly in young children, whose brains undergo rapid neural development from the last trimester in utero up through ages 1 to 2. Infants' brains expand quickly, then ruthlessly prune back brain cells - a process of orderly cell death, known as apoptosis. In an experiment in young rats undergoing this crucial stage of neural development, Christopher Turner, an assistant professor of neurobiology and anatomy at 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...
...separate area of research, Xie at Massachusetts General tested another anesthetic, isoflurane, on a 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...
...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. Ten years ago, for instance, lab researchers found evidence that isoflurane...
