    breaking: Fermilab physicists discover "doubly strange" particle
    Physicists of the DZero experiment at the US Department of Energy's Fermi National Accelerator Laboratory have discovered a new particle made of three quarks, the Omega-sub-b. The particle contains two strange quarks and a bottom quark (s-s-b). It is an exotic relative of the much more common proton and weighs about six times the proton mass.

    breaking: IOU for a particle physics detector
    In an era when high-energy physics experiments, and sometimes their approval processes, can last decades, it's an increasing rarity to find a project that lets collaborators work on all aspects of the research from start to finish.

    breaking: Dark matter illuminated
    A new study of an immense cosmic collision has provided confirming evidence for dark matter. The new results confirm those obtained from the 2006 study of the Bullet Cluster, providing a clear view of dark matter, separated from ordinary baryons.

    breaking: Can you predict Nobel Prize winners by counting citations?
    In a recently posted analysis of the bibliometrics surrounding the physics and chemistry Nobel Prize winners and nominees of the past 106 years, the answer turns out to be no.

    breaking: GLAST Observatory renamed for Fermi, reveals entire gamma-ray sky
    The US Department of Energy (DOE) and NASA announced today that the Gamma-Ray Large Area Space Telescope (GLAST) has revealed its first all-sky map in gamma rays. The onboard Large Area Telescope's (LAT) all-sky image--which shows the glowing gas of the Milky Way, blinking pulsars, and a flaring galaxy billions of light-years away--was created using only 95 hours of "first light" observations, compared with past missions which took years to produce a similar image.

    breaking: Free online: Full documentation for the Large Hadron Collider
    Want to read every single technical detail of the design and construction of the Large Hadron Collider and its six detectors? The whole shebang--seven reports totalling 1600 pages, with contributions from 8000 scientists and engineers--is available online.

    breaking: The Paul Revere of pulses
    The timing of a complicated device like a linear accelerator depends on a synchronizing pulse. But what kind of pulse is best? And is the type of pulse used at the Stanford Linear Accelerator Center merely a historical accident?

    breaking: Physicists shine light on the human brain
    In the new issue of Science Notes, Amber Dance describes how scientists at Stanford Linear Accelerator are using a beam of bright light to look for metal deposits in the human brain.

    breaking: The safety of switching on the Large Hadron Collider
    A new viewpoint essay by Michael Peskin provides a clear summary of the technical arguments showing there is negligible risk of the Large Hadron Collider producing dangerous microscopic black holes.

    breaking: ArgoNeuTs see first events
    A group of scientists known as the ArgoNeuTs--a word play on the Argonauts, the heroes of Greek mythology--have overcome the first hurdle in their scientific quest to observe neutrinos.

    breaking: Can science be funny?
    I was skeptical about whether a self-style "science comedian" could hold a stand-up for a full-length set, but Brian Malow gave the audience what they came for, and showed science can be funny to non-scientists.

    breaking: Twirl yourself dizzy in a virtual LHC
    Peter McCready has posted stunning 360-degree images that let you swoop around the big detectors at the Large Hadron Collider. Careful not to make yourself sick!

    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.
