...been chipping away at this mystery as best they can with the tools they have. One important clue comes from the observation of the most distant quasars--objects believed to be giant black holes swallowing huge volumes of gas at the cores of young galaxies. The Sloan Digital Sky Survey, a comprehensive scan of the heavens, has turned up several of these from about a billion years after the Big Bang. By watching how the light of quasars is altered by surrounding gas, astronomers have concluded that there was still some atomic hydrogen around then, although not much...
...hydrogen between the stars was well under way much earlier, just half a billion years post--Big Bang. "Theorists have been telling us that it should have happened fairly quickly once it began," says Michael Strauss, a Princeton University astronomer and deputy project scientist for the Sloan survey. "But the observations may be telling us otherwise...

More than half the population is still in exile, and huge swaths of New Orleans remain largely abandoned while residents wait for rebuilding money to arrive. Citywide some 60% of local businesses have most likely not reopened, according to a survey by Louisiana State University...
...conventional wisdom after Katrina was that most of the people who failed to evacuate were too poor to do so. But a recent survey of more than 2,000 respondents in eight hurricane-prone states showed that other forces may also be at play.
