    First it was Andy Warhol's obsolete digital archives and then the Lunar Orbiter Image Recovery Project. Now, the Hillman Photography Initiative's documentary team has set its sights on the CERN physics laboratory in its newest film, Subatomic. Famously known for housing the Large Hadron Collider (LHC), this facility is also home to the AEgIS experiment and the ATLAS Detector, one of the world's largest digital cameras. The scientists there use a variety of photographic technologies, from a cutting-edge 100-megapixel sensor that captures 600 million pictures per second, to antimatter experiments that use traditional photo emulsion to track particles. CERN even has an artist in residence program, showcasing outsider perspectives on the scientific world. These are all captured in this fifth and final installment of The Invisible Photograph film series from the Carnegie Museum of Art (CMOA) and Hillman Photography Initiative, which seek to reveal the hidden aspects of images whether obscured, lost or forgotten. Subatomic: The European Organizaton for Nuclear Research debuts online today, and you can watch the latest film below or stream the entire series on CMOA's website.

    The last time CERN and an angry bird met, it didn't end so well: the Large Hadron Collider overheated after a feathered creature reportedly dropped its breakfast on outdoor machinery. Things should go much more smoothly this time around, with CERN and Rovio partnering on an educational initiative that will be unveiled in full at the Frankfurt Book Fair on October 12th. Although the two are shy on just what's entailed beyond the presence of some Angry Birds material at the event, the union will mark the start of Rovio's learning brand and likely represent more in the long run than another Angry Birds Space tie-in. We're mostly wondering if subatomic physics research will explain why we still can't three-star some levels in a physics-based game. Update: Rovio and CERN announced "Angry Birds Playground" this morning, which the company describes as, "a learning program for 3- to 8-year-olds based on the Finnish National Curriculum for kindergarten." In so many words, CERN and Rovio are partnering on an educational initiative aimed at young children which employs the iconic Angry Birds characters. It's unclear whether the initiative will spawn games or books or ... what exactly, but there you have it.

  • CERN confirms existence of new particle consistent with Higgs boson (video)

    Physics' big announcement had more in common with a leaky product launch than the serious business of re-writing the science books. But slack asset management aside, it's official: a new boson has been observed with a standard deviation of 5 (confidence of 99.9%). The highly anticipated announcement came this morning direct from CERN's press conference (via ICHEP in Melbourne,) and is the result of an intense, ongoing search for the elusive particle. The observation is of a boson particle with a mass of 125.3 ± 0.6 GeV, at a significance of 4.9 sigma. Joe Incandela -- giving the presentation -- said that this is "In agreement with the standard model at 95% confidence range." The boson is the heaviest ever found, and although this is still a preliminary result, it's by far the strongest case yet for the existence of the elusive Higgs. The sought-after particle is essential for supporting the current understanding of sub-atomic world, and its bearing on nuclear, and electromagnetic interactions. The next stage will be to determine the exact characteristics of the new particle and whether it matches the expectations of the Higgs, or is it in fact something more "exotic." This part will take much more time, but for now, a (very) small, but important piece of the puzzle has been found. Update: We're sure you've got many questions, and CERN apparently anticipated this.

  • Higgs boson just may, possibly, more or less be proven to exist by ATLAS and CMS teams

    We had a false alarm over the possible discovery of the theory-unifying Higgs boson last year, but a bit of poking and prodding in subsequent months may well have given us much more definitive evidence of the elusive particle. According to some rare rumors emerging from Nature, both CERN's ATLAS and CMS detectors have seen particle decay signals suggesting the existence of Higgs to within a 4.5 to 5 sigma level of proof -- in other words, very nearly concrete evidence. That's not quite the 5-plus needed to settle the matter, but it's to a much higher level of certainty than before. As if to add fuel to the fire, ScienceNews even located a briefly posted, CERN-made video (sadly, since pulled) saying bluntly that the CMS team had "observed a new particle." Whether or not there's any substance is another matter. Nature hears that scientists are supposedly still working out what to say at an event on Wednesday, while CERN has made the slightly odd claim to ScienceNews that the yanked video is just one of several pre-recorded segments made to cover possible outcomes -- you know, in that "Dewey defeats Truman" sort of way. Unless the scientists have to go back to the drawing board, though, the focus from now on may be more on learning how Higgs behaves than its very existence. Any significant truth could see researchers proving the validity of the standard model of physics just as we're firing up our Independence Day barbecues.

  • Large Hadron Collider affected by full moon, ocean commiserates

    Large Hadron Collider not running properly? If you've read the docs and restarted it, check for a full moon. After noticing fewer particle collisions while on her shift, Pauline Gagnon reached out to a control room operator who casually explained that they adjust beam alignment during full moons. Yes, the tide-producing orbit of Earth's satellite tugs the LHC's inner workings ever so slightly askew. Though minute, the changes add up over the collider's 27km circumference and are picked up by monitoring equipment sensitive enough to measure elementary particles. However, Luna isn't the only thing that affects the accelerator -- the water level in Lake Geneva and passing high-speed rail trains also do the trick. Will your hand react differently to the LHC's beam under a Harvest Moon? Probably not. In any case, hit the source for the scientific details.

  • Large Hadron Collider to increase beam energy: Higgs boson can run, not hide

    We've seen the Large Hadron Collider running at a record-breaking 7 TeV for short periods, but now CERN is turning it up a notch (to 4 TeV from 3.5) for the rest of the year. The decision comes after an annual performance workshop last week in Chamonix and a report from the CERN Machine Advisory Committee (CMAC). The increase may seem modest compared to the knee-trembling levels of 7 TeV, but it's all part of a broader optimization strategy. Scientists state the new approach should increase the data collected in 2012 to 15 inverse femtobarns -- a three-fold jump from 2011. Even more encouraging is a statement from CERN's Research Director, Sergio Bertolucci, who claims that we should finally know for sure about the existence of the Higgs boson -- either way -- before the LHC enters a temporary shut-down period at the end of the year. Beam yourself over the break for the full press release.

    From Hollywood celebrities to the guy next door, millions of people have made World of Warcraft a part of their lives. How do you play WoW? We're giving each approach its own 15 Minutes of Fame. We interrupt our two-part interview with actor Kristian Nairn (Hodor in HBO's blockbuster new series, Game of Thrones) for a quick chat with ... a particle physicist at CERN, the world's largest particle physics laboratory in Geneva, Switzerland. Writes in-game buddy Fra (and thanks, Fra -- much love for all the EU players who brave the whole second language thing to send in tips!), "I have a friend which might be material for one of your interviews (which are great!). He is both good as a healer as he is a physicist. He also does some guides and public talks about his studies, and he is comprehensible even for a dumbass as me. :) I'm pretty sure you've a lot of nerds on your interview list, but a physicist working in one of the most famous labs is something ... new? He also does a lot of jokes about the not-so-good physics in game, or when people care of maximizing numbers that do not really change your game performance if you do all the math." A particle physicist who isn't into theorycrafting? We simply had to know more. Follow us past the break to learn how searching for the Higgs boson is like farming for a Swift White Hawkstrider (and come back next week for more with Game of Thrones' Kristian Nairn).

    The Large Hadron Collider is about to turn useful, people. Having recently jacked up its particle acceleration power to create 3.5 TeV (trillion electron volts) collisions, the researchers are today pressing ahead with plans to go to a full 7 TeV, which -- you won't be surprised to hear -- has never been done before. Provided the requisite 3.5 TeV per beam is reached, sustained and properly channeled into creating useful collisions, CERN will finally have the data it needs to start its long-awaited physics program based off the findings provided by the LHC. Best of all? The latest world record attempt is being broadcast live over the web right now so why not hit up that link below to witness some history in the making? Update: The momentous first protonic collisions at 7 TeV have just taken place, at just past 1PM CET. Now the time comes for researchers to parse all the incoming raw data, pore over it, analyze it, etc. We'll leave that to them, it's not like you can expect the God Particle to be discovered instantly. To fill the time, we invite you to come past the break for our blow-by-blow updating adventure from this morning plus video of the big moment.

  • Large Hadron Collider restart, end of the world pushed back to mid-November

    Still undecided about what to do with those precious few months before the biggest doomsday since Y2K? Then you're in luck, 'cause the much anticipated / feared restart of the Large Hadron Collider has now been delayed yet again, almost exactly a month after the last delay. This time it looks like a couple of vacuum leaks are the culprit, and CERN says that the collider is now unlikely to restart before mid-November, which just so happens to coincide with the peak of the Leonids meteor shower. Coincidence? Yes, yes it is.
