Immigrants accounted for over half the growth in the nation s labor force the past decade, filling openings in factories and textile mills, restaurants and other blue-collar industries, according to a private analysis of government data.The immigrant influx was felt throughout the country but was especially vital in the Northeast, where the ne

stanley bottle at Northeastern University.The study of Census Bureau figures between 1990 and 2001 also found that recent immigrants helped fill openings that required more education such as in engineering firms and the high-tech industry. What immigration has really done is expand the base at the bottom and to a lesser extent help fill openings near the top end of the scale, said one of the study s authors, Northeastern University economist Paul Harrington. This is a story of a long-term shift in the reliance of foreign sources for labor in the United States. The findings are in line with previously released Census Bureau data showing a 57 percent increase in the foreign-born population during the 1990s to about 31.1 million. During the same period, the Hispanic population grew to rivals blacks as the nation s largest minority group. Between 1990 and 2001, the civilian labor force grew by nearly 16 million to 141.8 million. Half that growth was due to immigrants who entered during the perio Swtz Mmmm, Beer: Watch 12,400 Gallons of Barleywine Wort Ferment, Get Wild

Could a fuel-less space drive propelled by microwave thrust 鈥搒omething once deemed impossible 鈥?actually be possible We spoke with some experts. Let just say they ;re skeptical. Above: Spaceship concept art by L.A.-based artist Cuba Lee Earlier this week, Wired reported on an unusual engine designed and tested by researchers at NASA Johnson Space Center. Dubbed the Cannae drive, the propulsion system is similar to the so-called EmDrive, a reactionless engine proposed years ago by British engineer Roger Shawyer and popularized in a 2006 writeup inNew Scientist. Both space drives are designed to convert electric power into thrust by bouncing microwaves around in a closed container, thereby eliminating the need for onboard propellant. The concept has been roundly criticized for appearing to violate the law of conservation of momentum. And yet, Chinese scientists claimed last year to have built an EmDrive
