  • US takes back supercomputing crown with world's fastest computer

    06/18/2012 8:12:23 PM PDT · by Ron C. · 22 replies ^ | 6/18/12 | FoxNews
    A U.S. supercomputer has won back the crown in the never-ending battle for the world's most powerful supercomputer. Its victory is the latest milestone marking the steady climb of computing power all across the globe. The Top500 industry list gave its No. 1 ranking to the Sequoia supercomputer housed at Lawrence Livermore National Laboratory in California — a spot earned by Sequoia's ability to crunch 16.32 quadrillion calculations per second (16.32 petaflops/s). Such supercomputing power is used by the U.S. National Nuclear Security Administration to simulate nuclear weapons tests for older weapons that have been sitting in the U.S. arsenal....

    Scientists discover global warming linked to increase in tropopause height over past two decades LIVERMORE, Calif. -- Researchers at the Lawrence Livermore National Laboratory have discovered another fingerprint of human effects on global climate. Recent research has shown that increases in the height of the tropopause over the past two decades are directly linked to ozone depletion and increased greenhouse gases. The tropopause is the transition zone between the lowest layer of the atmosphere -- the turbulently-mixed troposphere -- and the more stable stratosphere. The tropopause lies roughly 10 miles above the Earth's surface at the equator and five...
  • CLIMATE: Scientists return fire at skeptics in 'destroyed data' dispute

    Climate scientists are refuting claims that raw data used in critical climate change reports has been destroyed, rendering the reports and policies based on those reports unreliable. The Competitive Enterprise Institute, a free-market advocacy group, is arguing that U.S. EPA's climate policies rely on raw data that have been destroyed and are therefore unreliable. The nonprofit group -- a staunch critic of U.S. EPA's efforts to regulate greenhouse gases -- petitioned the agency last week to reopen the public comment period on its proposed "endangerment finding" because the data set had been lost (E&ENews PM, Oct. 9). But climate scientists...

    CALIFORNIA. Congresswoman Ellen Tauscher (D) was tapped this week to serve in the Obama Administration as US Undersecretary of State for Arms Control and International Security -- the Administration's top arms control negotiator. The centrist Tauscher -- who represents the CD-10 district which includes the Lawrence Livermore National Laboratory nuclear weapons/WMD research and development facility --- has been recognized as an expert on nuclear weapons issues during her seven-terms in Congress. "Keeping nuclear weapons out of the hands of terrorists, making sure other countries do not obtain them and, one day, I hope, ridding the world of these terrible weapons,...

    An internal audit has discovered that twenty computers have disappeared from a critical counterintelligence agency tasked with protecting America's nuclear secrets. Fourteen of the computers contained classified material, marking yet another in a string of embarrassments for the Department of Energy: The office in charge of protecting American technical secrets about nuclear weapons from foreign spies is missing 20 desktop computers, at least 14 of which have been used for classified information, the Energy Department inspector general reported on Friday. This is the 13th time in a little over four years that an audit has found that the department, whose...

    The Bush administration selected Lawrence Livermore National Laboratory's design for a new generation of atomic warheads, two officials familiar with the decision said Friday. The decision, to be announced later in the day, came a year after the administration ordered a competition between Lawrence Livermore near San Francisco and Los Alamos National Laboratory in New Mexico. The officials spoke on condition of anonymity because it had not been formally announced. The administration decided the design submitted by Lawrence Livermore, with engineering assistance from Sandia National Laboratories, could be built with greater confidence without underground testing because it was more closely...

    GREEN LLC wanted move toward nonproliferation Federal nuclear weapons officials have rejected a bid by disarmament and renewable energy activists to manage Lawrence Livermore weapons design lab, saying the "green team" didn't fit federal plans. The team, calling itself GREEN LLC, was led by two weapons-lab watchdog groups, Livermore-based Tri-Valley CAREs and Nuclear Watch of New Mexico, who never really expected to run the sprawling bomb lab. But they were offended that the National Nuclear Security Administration said the team's proposal ran afoul of federal law and "did not demonstrate an understanding of the requirements of the solicitation where it...

    For the first time in more than 20 years, U.S. nuclear-weapons scientists are designing a new H-bomb, the first of probably several new nuclear explosives on the drawing boards. If they succeed, in perhaps 20 or 25 more years, the United States would have an entirely new nuclear arsenal, and a highly automated factory capable of turning out more warheads as needed, as well as new kinds of warheads. "We are on the verge of an exciting time," the nation's top nuclear weapons executive, Linton Brooks, said last week at Lawrence Livermore weapons design laboratory. Teams of roughly 20 scientists...

    Word that Lawrence Livermore National Laboratory will install a battery of machine guns capable of spitting out 66 rounds a second with a range of nearly a mile was met by relief by some who think the weapons will deter terrorists but fear by others who worry they'll be caught in the line of fire. The guns, which the lab unveiled to much ado Thursday but has not yet installed, are meant to protect the laboratory's cache of radioactive plutonium, which terrorists might try to steal or destroy, sending a plume over much of the Livermore Valley. The weapons, called...

    LIVERMORE, Calif. (AP) - Officials at Lawrence Livermore National laboratory have added a new weapon to their armory, a high-powered gun that can fire 3,000 rounds a minute. The weapons, which are also to be installed at other facilities in the Energy Department complex, were displayed Thursday by Linton Brooks, head of the National Nuclear Security Administration. Brooks called the new weapons a way to make sure any attempt to storm the nuclear weapons lab is unsuccessful. "What we want to do is equip our protective force with the capability that will leave no doubt about the outcome," he said....

    LIVERMORE - Dozens of activists were arrested this morning in front of the west gate at Lawrence Livermore Laboratory as part of a protest honoring the 60th anniversary of the atomic bombing of Nagasaki. The march and rally, entitled "Nagasaki Never Again!," drew nearly 100 protesters -- about half of the number that showed up for a similar rally Saturday evening at the lab. That protest was one of four nationally coordinated rallies held that day at major U.S. weapons labs or test sites. All of the protests called for abolition of nuclear weapons and marked the 60th anniversary of...

    The Senate voted early yesterday morning to stop construction of the nation's costliest science project, a laser roughly the size of a football stadium that is meant to harness fusion, the process that powers the Sun. The project, the National Ignition Facility, or NIF (pronounced niff), is at the Lawrence Livermore National Laboratory in California and has cost $2.8 billion. About 80 percent complete, NIF is scheduled to be finished in 2009 at a cost of $3.5 billion and operate for three decades at an annual cost of $150 million, for a total of $8 billion. The Senate's action, part...

    WASHINGTON, May 6 - The cost to protect materials for nuclear bombs from terrorists is rising so high that the Energy Department will need to close some weapons laboratories, or at least consolidate the weapons fuel that they hold, government officials and outside experts are warning. Security costs threaten to eat into the budget for building and maintaining warheads, the experts say. After the Sept. 11, 2001, attacks, the department re-examined potential threats to the 13 laboratories and other plants across the country where it has what it calls "special nuclear materials," or plutonium and bomb-grade uranium. The department theorized...

    The Philippines has deported two US citizens who were arrested last year on suspicion of links to Muslim separatist groups. Brothers Michael Ray Stubbs, 55, and Jamil Daud Mujahid, 56, have been turned over to American marshals, who escorted them back to the US. The Immigration Bureau says both were blacklisted as "undesirable aliens and threats to national security". The two have been in detention since December after being arrested south of Manila. Authorities say the suspects were earlier seen meeting with leaders of the Abu Sayyaf and the separatist Moro Islamic Liberation Front (MILF). The Abu Sayyaf is a...

    'Parlor Maid' tarnishes FBI Details of Leung-Smith spy case throw bureau's handling of investigation into question Details of Leung-Smith spy case throw bureau's handling By Ian Hoffman, STAFF WRITER Twelve years ago, a team of U.S. counterintelligence operatives flew into frigid southern Manchuria to assess Chinese spying on American diplomats. Instead, the U.S. agents came to believe their own team was tracked by China's Ministry of State Security every step of their mission, which is still classified today. The first clue was an odd elevator encounter in remote northeast China, an FBI agent bumping into a California nuclear-weapons scientist suspected...

    Thunder, a supercomputer recently installed at Lawrence Livermore National Laboratory, is possibly the second-most powerful computing machine on the planet--and it was built by a company with about as many employees as a real estate office. California Digital, a 55-person company located on the outskirts of Silicon Valley, created Thunder from 1,024 four-processor Itanium 2 servers to perform a variety of tasks at the lab. Capable of churning 19.94 trillion operations per second, it would have ranked second in the Top 500 list of supercomputers published bi-annually by the University of Mannheim, the University of Tennessee and Lawrence Berkeley National...
