    breaking: Purdue "barn-raising" installs a Grid computer cluster, fast
    With the help of athletic rival Indiana University, Purdue University installed 1000 computers in a cluster the size of an 18-wheeler in just half a day -- a process that usually takes weeks. One of the users will be the Tier-2 data center at Purdue, which will collect and distribute data from the Compact Muon Solenoid experiment at the Large Hadron Collider. Check out the speedy video version and a cool trailer, as in preview.

    breaking: A droll, gleeful look at elements of the Periodic Table
    Chemists at the University of Nottingham have made a series of short videos, one for each element of the Periodic Table, and they are a hoot.

    breaking: Berkeley plan to demolish Bevatron has some concerned
    Lawrence Berkeley National Laboratory plans to tear down its historic Bevatron particle accelerator, which was instrumental in discoveries that led to four Nobel Prizes. Some residents of the area, however, want more environmental studies.

    breaking: What's colder than outer space? The LHC, soon.
    One of the most delicate and exacting parts of bringing the Large Hadron Collider into full operation is cooling the magnets in its 27-kilometer ring to a temperature of 1.9 degrees Kelvin. That's colder than deep space.

    breaking: Packing metal in fangs, claws and jaws
    Scorpions, crabs, worms and other creatures have metal atoms in their claws, jaws and fangs that make those structures significantly stronger and longer lasting. They're being surveyed with high-energy particle techniques.

    breaking: DAMA result is not "normal" dark matter
    The intriguing signal from the DAMA/LIBRA experiment in Italy has been ruled out as a sign of "normal" dark matter, according to new experimental data by the CoGeNT collaboration.

    breaking: Quick thinking helps experiment stay afloat
    The flood waters crept up. The lights went out. Yasar Onel and about a dozen of his students were not about to let angry Midwest weather wash away the University of Iowa's part in the world's largest physics experiment.

    breaking: ANTARES neutrino telescope complete
    The latest generation of neutrino telescopes uses vast bodies of salt water, fresh water, or ice as the medium for detecting neutrinos. The ANTARES experiment, which recently announced that it has completed construction, is the salt water version, based at the bottom of the Mediterranean Sea.

    breaking: It's official: Dark energy is in the dictionary
    It joins air quotes, edamame, dirty bomb, malware, mondagreen, and wing nut in the new edition of Merriam-Webster's Collegiate Dictionary. The physicist who coined the term says, "About time!"

    breaking: Physicists discover new particle: the bottom-most "bottomonium"
    Collaborators on the BaBar experiment at the Stanford Linear Accelerator Center have detected and measured, for the first time after a 30-year search, the lowest energy particle of the bottomonium family, called the eta-sub-b.

    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: Super B factories: competing proposals
    A next-generation type of particle collider called a Super B factory would push the intensity frontier to search for ultra-rare decays and perhaps find missing elements that go beyond the Standard Model of particle physics.

    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: 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.
