...after a year and a half of consistent economic decline, Britain announced that it had finally emerged from the recession. The downside? Its 0.1% fourth-quarter growth was not only about as small as could be but also well below what most experts had predicted. Worse still, some economists warn that the minuscule growth may be as good as the U.K. will muster for some time - and that its European neighbors aren't much better positioned to lead the region to a swift economic recovery...
Indeed, it is not difficult to imagine an alternate scenario in which critics would now be accusing the agency of failing to warn countries properly of the H1N1 threat. Hugh Pennington, a microbiologist at the University of Aberdeen who has advised the British government on past public-health crises, says the WHO was obligated to raise the alarm as soon as H1N1's spread matched the medically accepted definition for a pandemic. He points out also that early news reports from Mexico and the U.S., where the virus first emerged, suggested a highly lethal disease...
...only big brand whose consumer cameras have displayed an occasional - though clearly unintentional - bias toward Caucasian faces. Face detection, one of the latest "intelligent" technologies to trickle down to consumer cameras, is supposed to make photography more convenient. Some cameras with face detection are designed to warn you when someone blinks; others are programmed to automatically take a picture when somebody smiles - a feature that, theoretically, makes the whole problem of timing your shot to catch the brief glimpse of a grin obsolete. Face detection has also found its way into computer webcams, where it can track a person...

Unlike mutual funds, investors face price spreads when buying and selling ETFs, and these spreads can be quite wide - spanning several percentage points in some cases - when the ETF is small or its underlying stocks don't trade much...
...authors warn that their findings, while important, are not the final word and must be validated by others. Bender, Knutson and their colleagues ran the simulation using an average of 18 climate models at once, then reran it with four models individually. One of the models, Bender says, showed a decrease in the most powerful storms, demonstrating once again that the effects of climate change are complex and not easily predicted...
