Former Spy Poisoned By Radiation In UK 432

An anonymous reader writes "BBC new is reporting the death of the ex-Russian spy Alexander Litvinenko with a major dose of radioactive polonium-210. But nobody knows how it got there. Suspicions have fallen upon the Russian security services (who deny involvement). The task of the pathologists now is to unpick what really killed him and how it was administered. Quite what techniques they will use to solve this puzzle is unclear." From the article: "A post-mortem examination on Mr Litvinenko has not been held yet. The delay is believed to be over concerns about the health implications for those present at the examination. But Roger Cox from the HPA said a large quantity of alpha radiation emitted from polonium-210 had been detected in Mr Litvinenko's urine."

'Long Tail' May Not Wag the Web Just Yet 132

Carl Bialik from WSJ writes "Expanding on an article he wrote in 2004 (and discussed on Slashdot), Wired magazine editor Chris Anderson argues in his best-seller 'The Long Tail' that the web is changing commerce from a hit-driven business to one focused on niches. But Wall Street Journal columnist Lee Gomes questions Anderson's data, and adds, 'I don't think things are changing as much as he does.' Gomes writes, 'At Apple's iTunes, one person who has seen the data -- which Apple doesn't disclose -- said sales "closely track Billboard. It's a hits business. The data tend to refute 'The Long Tail.' " ' On his blog, Anderson responds that Gomes 'stumbles over statistics and more, and in the end simply makes a muddle of what might have been an interesting debate over the magnitude of the Long Tail effect.'"
