    breaking: American Metric
    The National Institute of Standards and Technology recently published its 8th edition of the English language SI Units Brochure: a complete guide to the International System of Units: now the metric system of choice for the US. Rush out and pick up your "Americanized" brochure to get the scoop on which units made the cut, which ones didn't, plus how to spell "meter" and "liter" the American way.

    breaking: A new era of synchrotron science at SLAC: PEP-X
    By capitalizing on hardware and infrastructure already in place, a new synchrotron storage ring project, "PEP-X," would catapult SLAC even further beyond the research capabilities available at existing photon science laboratories.

    breaking: GLAST spacecraft powered up and sending data
    After their journey into the cold reaches of space, instruments on the Gamma-ray Large Area Space Telescope have been woken up ready to begin operations. Data from the Large Area Telescope (LAT), one of two instruments aboard GLAST, is arriving at the Stanford Linear Accelerator Center’s Instrument Science Operations Center where it will be monitored, processed, and distributed to the rest of the science team worldwide.

    breaking: What do the DAMA dark matter results mean?
    Might the recent dark matter results from the DAMA collaboration be a sign of low-mass dark matter particles, and not in contradiction with other dark matter experiments?

    breaking: Dispelling science stereotypes one single at a time
    Particle astrophysicist Mark Jackson stood in the swanky Museum of Contemporary Art surrounded by many of the city's rich and influential. While few people likely understood what he does for a living--study black holes and primordial ooze left over from the big bang--they did understand his nonacademic title: One of Chicago's top 10 bachelors.

    breaking: The LHC as a massive grid computer
    From one angle the Large Hadron Collider is a particle collider; but from another, it's a massive grid computer with the collider as its CPU, according to a rich and highly readable overview by Tim O'Brien.

    breaking: Diploma mill proprietors plead guilty
    Diploma mills, which issue false university qualifications for money, suffered a major blow with one of the largest cartels pleading guilty to charges. George Gollin discussed the problem in symmetry in 2006 and the New York Times now reports on the results of indictments.

    breaking: US House and Senate pass bill with more science funding
    Last night, the US Senate voted to approve an emergency funding bill including $62.5 million for the Department of Energy's Office of Science. The funding will allow Fermilab to stop its involuntary layoff program that had been scheduled for next month.

    breaking: SLAC, Lawrence Berkeley Lab, and J-Lab join SCOAP3
    Stanford Linear Accelerator Center, Lawrence Berkeley National Laboratory, and Jefferson Lab have joined the SCOAP3 consortium, which is developing a new model for funding peer-reviewed journals.

    breaking: US LHC construction declared formally complete
    The decade-long project to help build CERN's LHC accelerator, and the ATLAS and CMS detectors, culminated yesterday (June 25) when Dr. Raymond L. Orbach, Department of Energy under secretary for science and director of the Office of Science, announced the formal completion of the US LHC construction project.

    breaking: A quick, easy way to grill candidates on science policy
    Sixteen prominent science and engineering organizations have sent a questionnaire to every Congressional candidate across the nation, asking where they stand on seven key areas of science and technology policy. And they've made it easy for you to do the same.

    breaking: The birth of Free Electron Lasers
    Continuing with the APS milestone series celebrating 20th century achievements in physics, the 1976 milestone includes two letters that together detail the first experimental demonstration of a working free electron laser (FEL), in which a beam of unbound electrons is made to travel through a periodic magnetic field and generate a beam of light.

    breaking: Can you hear me now?
    In a large laboratory with facilities built in tunnels underground, how do people communicate on the job? SLAC intern Calla Cofield discovers how radio transmission works underground and above.

    breaking: The twisted physics of cartoons and anime
    Who said laws of physics don't apply in anime and cartoons? They just don't follow our laws!

    breaking: The Large Hadron Collider is safe
    CERN today issued an update of their safety report for the LHC as part of an LHC status update. The safety report reaffirms and extends the conclusions of the 2003 report: that the LHC collisions present no danger and there is no reason for concern.

    breaking: Are the laws of physics the same throughout the universe?
    Observations of a quasar about 6 billion light years from Earth have shown that one of the fundamental properties of physics is the same there as here.

    breaking: Crash-testing a chiller
    Particle physicists have the reputation that they need to smash things up in order to find out what they are about. Sometimes accelerator physicists get to smash stuff up, too: a group of engineers and technicians recently crash-tested a full cryomodule.

    breaking: Wine label science
    No, it's not an academic study of what it takes to market a wine successful using scientific measures and metrics. This is merely a place for us to collect science-themed wine labels we've seen around the place. If you have a wine label to add, let us know (and send us a pic).

    breaking: A monument befitting a particle
    The Egyptians built pyramids to honor their pharaohs. The Greeks built temples to honor their gods. So why shouldn't particle physicists construct office buildings (even if virtually) to honor the prize of their scientific quests.
