    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: 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.

    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: 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: Fermilab's DZero experiment weighs in on W boson mass
    The DZero experiment at Fermilab's Tevatron collider made public today its most precise measurement of the mass of the W boson. Knowing the mass of this force-carrying elementary particle confirms the Standard Model of particle physics and puts constraints on the mass of the Higgs boson.

    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.

    feature: The Tevatron's proud legacy
    Just after 2:30 p.m. on Sept. 30, Fermilab accelerator pioneer Helen Edwards prepared to stop the circulation of subatomic particles in the Tevatron collider for the last time. She was a fitting choice; Edwards and her husband, Don, had led the Tevatron start-up nearly three decades earlier. Now she would lay the massive collider to rest.

    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.

    breaking: Tevatron experiments close in on Higgs particle
    Scientists of the CDF and DZero collaborations at Fermilab continue to increase the sensitivity of their Tevatron experiments to the Higgs particle and narrow the range in which the particle seems to be hiding.

    breaking: Higgs buzz at summer physics conference 
    Physicists could be on their way to discovering the Higgs boson, if it exists, by next year. Scientists in two experiments at the Large Hadron Collider pleasantly surprised attendees at the European Physical Society conference this afternoon by both showing small hints of what could be the prized particle in the same area. “This is what we expect to find on the road to the Higgs,” said Gigi Rolandi, physics coordinator for the CMS experiment.

    breaking: How to find the Higgs particle; first Higgs search results from LHC and Tevatron
    Editor's note: story updated at noon CDT on July 22: The LHC experiments reported at the EPS meeting a tantalizing excess of Higgs-like events, short of claiming a discovery, but very intriguing nevertheless. See the Higgs search at the LHC section further below for more information on these results.
