    USA TODAY - Largest particle collider conducts successful test

    The world's largest particle collider passed its first major test by firing a beam of protons around a 17-mile underground ring Wednesday in what scientists hope is the next great step to understanding the makeup of the universe.

    After a series of trial runs, two white dots flashed on a computer screen at 10:26 a.m. indicating that the protons had traveled the full length of the $3.8 billion Large Hadron Collider described as the biggest physics experiment in history.

    "There it is," project leader Lyn Evans said when the beam completed its lap.

    Champagne corks popped in labs as far away as Chicago, where contributing and competing scientists watched the proceedings by satellite. Physicists around the world now have much greater power to smash the components of atoms together in attempts to learn about their structure.

    "Well done, everybody," said Robert Aymar, director-general of the European Organization for Nuclear Research, to cheers from the assembled scientists in the collider's control room at the Swiss-French border.

    The organization, known by its French acronym CERN, began firing the protons a type of subatomic particle around the tunnel in stages less than an hour earlier, with the first beam injection at 9:35 a.m.

    Now that the beam has been successfully tested in a clockwise direction, CERN plans to send it counterclockwise. Eventually two beams will be fired in opposite directions with the aim of recreating conditions a split second after the big bang, which scientists theorize was the massive explosion that created the universe.

    "My first thought was relief," said Evans, who has been working on the project since its inception in 1984. "This is a machine of enormous complexity. Things can go wrong at any time. But this morning has been a great start."

    He didn't want to set a date, but said that he expected scientists would be able to conduct collisions for their experiments "within a few months."

    The collider is designed to push the proton beam close to the speed of light, whizzing 11,000 times a second around the tunnel.

    Scientists hope to eventually send two beams of protons through two tubes about the width of fire hoses, speeding through a vacuum that is colder and emptier than outer space. The paths of these beams will cross, and a few protons will collide. The collider's two largest detectors essentially huge digital cameras weighing thousands of tons are capable of taking millions of snapshots a second.

    The CERN experiments could reveal more about "dark matter," antimatter and possibly hidden dimensions of space and time. It could also find evidence of the hypothetical particle the Higgs boson which is sometimes called the "God particle" because it is believed to give mass to all other particles, and thus to matter that makes up the universe.

    The supercooled magnets that guide the proton beam heated slightly in the morning's testing, leading to a pause to recool them before trying the opposite direction.

    The start of the collider came over the objections of some who feared the collision of protons could eventually imperil the Earth by creating micro-black holes, subatomic versions of collapsed stars whose gravity is so strong they can suck in planets and other stars.

    "It's nonsense," said James Gillies, chief spokesman for CERN.

    CERN was backed by leading scientists like Britain's Stephen Hawking, who declared the experiments to be absolutely safe.

    Gillies told the AP that the most dangerous thing that could happen would be if a beam at full power were to go out of control, and that would only damage the accelerator itself and burrow into the rock around the tunnel.

    Nothing of the sort occurred Wednesday, though the accelerator is still probably a year away from full power.

    The project organized by the 20 European member nations of CERN has attracted researchers from 80 nations. Some 1,200 are from the United States, an observer country that contributed $531 million. Japan, another observer, also is a major contributor.

    Some scientists have been waiting for 20 years to use the LHC.

    The complexity of manufacturing it required groundbreaking advances in the use of supercooled, superconducting equipment. The 2001 start and 2005 completion dates were pushed back by two years each, and the cost of the construction was 25% higher than originally budgeted in 1996, Luciano Maiani, who was CERN director-general at the time, told The Associated Press.

    Maiani and the other three living former directors-general attended the launch Wednesday.

    Smaller colliders have been used for decades to study the makeup of the atom. Less than 100 years ago scientists thought protons and neutrons were the smallest components of an atom's nucleus, but in stages since then experiments have shown they were made of still smaller quarks and gluons and that there were other forces and particles.

    RIM launches first BlackBerry flip phone

    Wednesday, Sep 10, 2008 4:5PM UTC

    By Wojtek Dabrowski

    TORONTO (Reuters) - Research In Motion Ltd is launching a flip version of its popular BlackBerry Pearl smartphone, a move that reasserts its push into the retail consumer market.

    Like RIM's original Pearl model, the first-ever flip BlackBerry comes loaded with multimedia features such as a video and music player and a 2-megapixel camera with flash, as well as a Web browser and an abridged keyboard.

    "Seventy percent of the mobile phone users in the United States use a flip," RIM co-CEO Jim Balsillie said in an interview. "There's never been a smartphone or a BlackBerry option for that."

    He added the new device is "extremely important" to capturing more retail users.

    The new clamshell flip BlackBerry will be available around the world starting this autumn. In the United States, T-Mobile will be the exclusive launch carrier. No pricing details were immediately available.

    RIM's volatile shares jumped early on Wednesday, rising $3.37, or 3.4 percent, to $102.67 on the Nasdaq market. In Toronto, they rose C$4.20 to C$110.23.

    The first, candy-bar-shaped version of the Pearl was launched in September 2006 to rave reviews and strong sales. Its success was a key factor behind the Waterloo, Ontario-based company's ability to deliver banner results throughout the rest of that year and in 2007.

    The Pearl also allowed RIM to broaden its market beyond its mainstay of executives, lawyers, politicians and other professionals who use the BlackBerry to send work e-mail securely.

    RIM has more than 16 million subscribers. It says that "non-enterprise" customers -- the company's term for small and medium businesses and consumers -- now represent more than 40 percent of that total.

    The drive for retail consumers has put the company in more direct competition with hardware makers such as Apple and its iPhone, as well as Motorola and Nokia. Balsillie has repeatedly dismissed competitive concerns and they have yet to translate into lower sales.

    Despite that, RIM's shares have lost about a third of their value since setting a year high of $148.13 on the Nasdaq in June.

    Most analysts continue to recommend RIM's shares to investors, according to Reuters Knowledge. Some cite a strong slate of upcoming product launches including the recently unveiled BlackBerry Bold, as well as continuing strong demand for smartphones.

    Asked whether the market should expect RIM to launch additional BlackBerry models before the end of the calendar year, Balsillie replied: "We're far from done."
