    breaking: Scientists complete the top quark puzzle
    Fermilab’s CDF and DZero experiments have discovered the last predicted way to produce the top quark, the heaviest elementary particle.

    breaking: Physicists show strengthened signals of Higgs-like particle in publications
    The CMS and ATLAS experiments at CERN’s Large Hadron Collider released papers Tuesday confirming their earlier simultaneous, independent discovery of a particle that resembles the Standard Model Higgs boson.

    feature: Particle physics tames big data
    As science produces an ever-growing flood of information, researchers in many fields struggle with how to collect, store, manage and distribute “big data.” Perhaps they could learn a thing or two from particle physics, a field that's been awash in enormous data sets for decades.

    breaking: The unreasonable Tevatron: Calculating the economic impact of basic science
    During a recent symposium at Fermilab, a speaker took the stage to defend government investment in basic science. He used an odd tactic: He called particle physics unreasonable.

    breaking: Guests take a peek inside Tevatron experiments
    In connection with a symposium celebrating the Tevatron, Fermilab scientists gave special tours of the collider's two experiments. A reporter from Naperville Community Television Channel 17 took the opportunity to visit the detectors and filed this report.

    signal to background: Shmoos of the Tevatron
    Particles like the top quark weren’t the only characters to appear at Fermilab’s Tevatron. A physicist waxes nostalgic as scientists prepare to celebrate the accelerator’s contributions to science, technology and society at a symposium this month.

    breaking: More physics for your funding
    The decommissioning of the Tevatron represented the end of an era, but it also is ushering in the next generation of physics by providing valuable equipment to other experiments.

    breaking: Scientists continue to see puzzling behavior in top quarks, reaffirm strength of Tevatron experiments
    The Tevatron may be shut down for good, but – as evidenced by the catalogue of results presented at this week’s Rencontres de Moriond conference – the collider’s experiments still have plenty to say. In some areas, the Fermilab experiments still hold the advantage over those at the higher-powered Large Hadron Collider at CERN.

    breaking: Tevatron experiments see possible signs of the Higgs boson in favored region
    Tevatron physicists told attendees of the Rencontres de Moriond conference this morning that they had found excesses in their data suggestive of a Higgs with a mass between 115-135 gigaelectronvolts. A few months ago, LHC physicists announced similar bumps indicating a Higgs with a mass of between 124-126 GeV.

    breaking: World's best measurement of W boson mass tests Standard Model, Higgs boson limits
    Today, scientists from the CDF collaboration have unveiled the world's most precise measurement of the W boson mass, based on data gathered at the Tevatron accelerator. The precision of this measurement surpasses all previous measurements combined and restricts the space in which the Higgs particle should reside according to the Standard Model, the theoretical framework that describes all known subatomic particles and forces.

    breaking: The Tevatron's enduring computing legacy
    Over the course of more than three decades of planning and operation, a tremendous amount of computing innovation was necessary to keep the data flowing and physics results coming at Fermilab's Tevatron. In fact, computing continues to do its work. Although the proton and antiproton beams no longer brighten the Tevatron’s tunnel, physicists expect to be using computing to continue analyzing a vast quantity of collected data for several years to come.

    breaking: The Tevatron: a training ground beyond particle physics
    Beyond smashing together billions of protons and antiprotons over the course of its 28 years of operations, Fermilab’s Tevatron also served as a launching pad for many careers, often in fields beyond particle physics.

    breaking: Tevatron operations: A way of life
    This afternoon, Sept. 30, Fermilab will shut down the Tevatron for the last time. This story honors the operators - the men and women who have kept the accelerators running 24 hours a day, seven days a week, 365 days a year.

    breaking: Fermilab's Antiproton Source: A rich history and an exciting future
    Fermilab’s Antiproton Source has long produced the antimatter that makes Fermilab’s particle collisions possible. While the Antiproton Source will shut down along with the Tevatron on Sept. 30, there are plans for its future.

    breaking: Tevatron shutdown eve
    On the eve of the shutdown of Fermilab's Tevatron, collaborators from the CDF and DZero experiments are expressing their gratitude for all the hard work and dedication that made 26 years of capturing billions of proton and antiproton collisions possible. In these final hours of operations, both collaborations are making the pen mightier than the proton by writing notes of thanks and appreciation.
