    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: 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.

    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.
