There's little question that China desperately wants its team to avoid scandal in Beijing. Any drug-tainted performance will be a huge loss of face for a country that wants to prove that its athletic successes can come naturally. In the run-up to Beijing, just before American swimmer Jessica Hardy was cut from the U.S. swimming team because of a positive doping test, China, too, busted its best men's backstroker, Ouyang Kunpeng, for steroid use and slapped him with a lifetime ban. Ouyang claimed that the anabolic agent entered his system through contaminated food, not through deliberate...
...gilt-edged windows dating from the Russian Empire. Amaglobeli's family became refugees during the Abkhazia conflict in 1992. He says the current crisis is stirring bad memories. "I remember the smell of gunfire, the smell of war in the air. It was very painful to see the loss of territory, people falling into poverty." A teenager at the time, Amaglobeli now is an adult with a BlackBerry that rings persistently with panicky questions from family members. "I tell them to be calm but stay vigilant, and if the time comes, leave," he says...
...faulted and tripped off-line. This is also something that happens pretty frequently on the U.S.'s massive electrical grid. But the breakdown of that line in northern Ohio began a cascade of failures that, in a little more than an hour, led to a near total power loss for more than 50 million people in the northeastern U.S. and parts of Canada. Full power wouldn't be restored for everyone in the affected area until Aug. 18. It was the largest blackout in North American history - and five years later, with the grid sagging again under the weight...
...vulnerable our electric grid has become. When that first transmission line in northern Ohio went off-line, it wiped out the redundancy and excess capacity built into the northeastern grid - and more things went wrong. First Energy, which was responsible for powering northern Ohio, should have detected the loss of that first line, but its energy management system wasn't working at the time (the company didn't know that). Higher up, the Midwest Independent System Operator's state estimator, which helps ensure reliability for several utility companies in the region, had just been taken down for troubleshooting that...
...scale," says Daigle. He notes that last year's federal energy act contained authorization for smart grid investment - but no money has been appropriated yet. That needs to change. As electricity demand increases in the U.S. and we become ever more networked, the consequences of a major power loss worsen as well. The blackout of 2003 cost some $6 billion, but it could have been far more costly. A smarter grid can also help improve energy efficiency - if customers and utilities know exactly how much electricity they are using in real-time, they should be able to cut waste. Five...
