    breaking: On course for a convincing supernova
    The historic failure of supernovae simulations to achieve robust explosions is now being treated with models that focus on magnetic field effects. A summer student at Stanford Linear Accelerator Center is working to make the supernovae explode in the computations of a computer.

    breaking: New issue of symmetry available
    In the August 2008 issue of symmetry, read about the three-pronged approach to particle physics discoveries recently announced in a strategic planning document; ArgoNeuT, a liquid-argon-based detector looking for neutrinos; and the symmetry collection of physics-based license plates.

    breaking: First protons injected into the LHC
    The Large Hadron Collider saw its first protons today, around 6:30 p.m. at CERN (12:30 p.m. US EDT), as scientists conducted the first beam injection test in one section of the collider.

    breaking: Most everything you wanted to know about, well, everything....
    If you always wanted to know more about science but don't have time to go back to school or visit your neighborhood laboratory, Fermilab has an online library made just for you.

    breaking: CERN first beam due September 10, 2008
    CERN officially announced today that the first attempt to circulate a beam through the Large Hadron Collider will be made on September 10, 2008.

    breaking: Amateur finds new cosmic object
    A Dutch schoolteacher with no previous interest in science has identified a new type of cosmic object. The object is a green blob of gas that was once powered by a quasar now gone dim. Professional astronomers confirm that object is one of a kind.

    breaking: Particle physics is a dirty, dirty job
    Being a particle physicist doesn't conjure up images of getting your hands dirty. But in tasks that rival those featured in a recent spate of television programs about the world's dirtiest jobs, neutrino physicist Mark Vagins has a lot to contend with working underground on the Super-Kamiokande experiment in Japan.

    breaking: Preparing the next generation of neutrino physicists
    Georgia Karagiori and Matt Taub want to build a giant, super-intense laser with a 100-kilometer beamline to detect "relic neutrinos" from 14 billion years ago. This cosmic neutrino spectrometer could some day explain how the universe evolved two or thee seconds after the big bang.

    breaking: Fermilab zooms in on the Higgs boson
    Scientists working on the CDF and DZero experiments at the Fermi National Accelerator Laboratory are entering Higgs territory. On Sunday, the two groups reported at a conference in Pennsylvania that for the first time their results directly restrict the allowed mass range for the elusive Higgs boson.

    breaking: Coming soon: First coffee-table book by a high-energy physics experiment
    Photographer Claudia Marcelloni explains it this way: "If you're a particle physicist, and you're at a party and someone says 'So what do you do?' you show them this book and that explains it."

    breaking: A prelude to the Higgs
    Smaller cross sections mean more sensitive detection ability is needed to spot certain fundamental processes. The observation of the ZZ process shows that Fermilab physicists are nearly at the level required to observe the Higgs boson decaying into two W bosons.

    breaking: Particle accelerator reveals hidden Van Gogh
    Work at Hamburg's DESY lab reveals the somber portrait of a peasant woman beneath a sunny impressionistic painting.

    breaking: Got enough physics?
    If you're one of those people who can never have enough physics in your life, you may enjoy digging around the physics-related shirts, mugs, clocks, and other merchandise available on the Internet.

    breaking: GLAST reports first observation
    A few days after it turned on, the main instrument on the Gamma-ray Large Area Space Telescope began observing an extraordinarily bright gamma-ray blazar known as 3C 454.3, according to a new report.

    breaking: New clue to Fermilab code
    Will this be the clue that cracks the hieroglyphic middle section of the coded letter? Or persuades the code maker to come forward?

    breaking: How can the LHC be colder than space if space has no temperature?
    The answer, via Bad Astronomy, involves emptiness, photons and the Mini Marshmallow of Science.

    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.
