    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.

    The cat would appear to be out of the bag, but if you must find out about the status of the Higgs boson search ASAP, check the video stream (embedded after the break) as CERN scientists reveal whatever it is they've found. The webcast is scheduled to kick off at 2:55AM ET, as a prelude to this year's ICHEP particle physics conference in Melbourne. Whenever the announcement comes we'll be sure to let you know, check the links below for more information. Update: So yeah, they've found a new particle "consistent with Higgs boson," check out all the details here.

  • 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.

  • CERN admits faulty kit to blame for speedy neutrinos, says it's all relative

    Those pesky neutrinos, they sure did cause a kerfuffle. The scientific community held its collective breath when research published by CERN suggested that the little guys had been caught traveling at an Einstein-defying 3.7 miles per second faster than light. Naturally there was a mixture of doubt and excited disbelief, but everything needed to be triple checked before any paradigms could meet any windows. And alas, it was all to unravel once flaws were identified. CERN has finally admitted faulty kit was to blame, with it's research director Sergio Bertolucci conceding "A coherent picture has emerged with both previous and new data pointing to a neutrino velocity consistent with the speed of light." The final chapter in this story took place at the International Conference on Neutrino Physics and Astrophysics in Kyoto today, with Bertolucci also commenting that, at the very least, the story captured the public imagination, pointing out that "An unexpected result was put up for scrutiny, thoroughly investigated and resolved in part thanks to collaboration between normally competing experiments. That's how science moves forward." [Image credit: Getty Images]

  • 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.

    Sure, concerns about the Large Hadron Collider creating a world-destroying black hole may have been more or less put to rest, but there's still plenty of pressing questions that remain unanswered. Like, what would happen if you put your hand in the beam? The folks from Sixty Symbols recently asked some physicists that very question and got some rather puzzled responses, so they went straight to CERN itself to get a definitive answer. You can see that in full after the break, but the short version is that it's something like the force of a moving aircraft carrier concentrated down to a laser-like one-millimeter-wide beam (accompanied by a wider beam of particles that would irradiate your entire body). Bad news. As they're quick to point out, though, actually getting anywhere near the beam is virtually impossible.

  • Huawei throws R&D dollars at gesture control, cloud storage, being more 'disruptive'

    Undeterred by the fact that even humans struggle to interpret certain gestures, Huawei says it's allocating a chunk of its growing R&D budget to new motion-sensing technology for smartphones and tablets. The company's North American research chief, John Roese, told Computerworld that he wants to allow "three-dimensional interaction" with devices using stereo front-facing cameras and a powerful GPU to make sense of the dual video feed. Separately, the Chinese telecoms company is also putting development cash into a cloud computing project that promises to "change the economics of storage by an order of magnitude." Roese provided scant few details on this particular ambition, but did mention that Huawei has teamed up with CERN to conduct research and has somehow accumulated over 15 petabytes of experimental physics data in the process. Whatever it's up to, Huawei had better get a move on -- others are snapping up gesture recognition and cloud patents faster than you can say fa te ne una bicicletta with your hands.

    Got questions for CERN crew? We know we do. For instance, if a Higgs boson falls in the woods and no one is around to hear it, does it still create a miniature black hole that swallows the Earth and destroys us all? Well if you've got queries for the folks working the LHC, attempting to unlock the secrets of the universe then hit up the source link for a live Hangout at that most nerdy of social networks Google+. The conversation starts at 1 pm eastern time.

  • 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.

  • LHC discovers 'particle', starts repaying back that five billion

    The Large Hadron Collider at CERN was built to discover new life forms and new civilizations particles to complete the Standard Model of physics, of which the Higgs-Boson is only a part. The $5 billion project has finally found something previously unseen, according to the BBC. ATLAS has picked up Chi-b 3P: a Boson (building block of nature) Meson comprised of a "beauty quark" and a "beauty anti-quark," bound together with a strong nuclear force -- believed to exist in nature, but never seen until now. Yesterday's discovery is so new, it hasn't even had a sigma rating yet, but we don't expect CERN to confirm the find until its next two hour keynote. Update: The initial report described the particle as a Boson (elemental force carriers), it is in fact a Meson (which comprise of a quark and an anti-quark).

    Did you know that the Large Hadron Collider at CERN has already produced 100 petabytes of data that needed to be sent out to labs across the world for analysis? Pushing that amount of information across the Internet is a gargantuan task, which is why Caltech teamed up with the Universities of Victoria, Michigan and Florida (International) amongst others to try and break the internet speed record. Using commercially available gear (including Dell servers with SSDs), it was able to push 98Gbps and pull 88Gbps down a single 100Gbps fibre-optic connection between the Washington State convention center in Seattle and the University of Victoria computing center in British Columbia. Head on past the break for a video that shows you how it was done and why it probably won't be commercially available in time to super-size your Netflix queue.

  • CERN: 'Don't believe the Higgs-Boson hype' (update: not yet)

    CERN is pouring cold water on the rumor it's gonna announce the discovery of the Higgs at today's seminar in Zurich. For the uninitiated: the Higgs-Boson is the particle that is believed to give all things mass: it surrounds us, penetrates us and binds the galaxy together. The scuttlebutt is that the ATLAS sensor picked up a Higgs with a mass of 125GeV (gigaelectronvolts) and rated at three-point-five-sigma -- a one sigma barely warrants a mention, a five-sigma is a bona-fide scientific discovery. CERN hasn't confirmed or denied anything, claiming it's still got five inverse femtobarns worth of data (roughly 5 x 70 x 10^12 of individual collisions) to examine before it can be sure, so just chuck the one bottle of champagne into the refrigerator -- better to be safe, eh? Update: Looks like we don't need to bust out the bubbly, after all. The conclusion from the two-hour presentation is that the ATLAS detector has been able to narrow down the region it believes the Higgs is in to 115.5GeV to 131GeV and that any discovery so-far only has a rating of two point three sigma. The CMS is similarly inconclusive, with results bobbing around the two sigma region. In short, whilst they know where they should look, they haven't been able to find one -- yet.

  • Faster-than-light neutrinos are back in the game

    Back in September, CERN dropped the improbable news about its faster-than-light neutrinos, causing eggheads worldwide to cry foul. Understandable really, as if true, a lot of what we think we know about the universe essentially falls apart. So, expect severe bouts of head-scratching once more, as a second round of experiments from the same OPERA collaborative has reported similar results. The initial experiments used a long chain of neutrinos, fired from point A to B. Skeptics claimed that this might have introduced an element of uncertainty to the results -- the new tests used much shorter blasts, meaning that if they arrived just as quickly, then this potential cause for error is scratched out. The new data still needs to undergo the usual peer review, and other possible causes for error remain. For now though, it looks like one of the main arguments against has been addressed, making the Einstein-challenging neutrinos one step closer (or is that ahead?) to re-writing the rule book.

    A week ago the world went wild over CERN's tentative claim that it could make neutrinos travel faster than light. Suddenly, intergalactic tourism and day trips to the real Jurassic Park were back on the menu, despite everything Einstein said. Now, however, a team of scientists at the University of Groningen in the Netherlands reckons it's come up with a more plausible (and disappointing) explanation of what happened: the GPS satellites used to measure the departure and arrival times of the racing neutrinos were themselves subject to Einsteinian effects, because they were in motion relative to the experiment. This relative motion wasn't properly taken into account, but it would have decreased the neutrinos' apparent journey time. The Dutch scientists calculated the error and came up with the 64 nanoseconds. Sound familiar? That's because it's almost exactly the margin by which CERN's neutrinos were supposed to have beaten light. So, it's Monday morning, Alpha Centauri and medieval jousting tournaments remain as out of reach as ever, and we just thought we'd let you know.

  • Pour one out for the Tevatron particle accelerator, because it's shutting down today

    The eyes of the physics community are collectively fixed upon Illinois today, where, later this afternoon, researchers at Fermilab will shut down the Tevatron particle accelerator... for good. That's right -- the world's second-largest collider is being laid to rest, after a remarkable 25-year run that was recently halted due to budgetary constraints. Earlier this year, Fermilab's scientists and a group of prominent physicists pleaded with the government to keep the Tevatron running until 2014, but the Energy Department ultimately determined that the lab's $100 million price tag was too steep, effectively driving a nail through the accelerator's subterranean, four-mile-long coffin. First activated in 1985, the Tevatron scored a series of subatomic breakthroughs over the course of its lifespan, including, most notably, the discovery of the so-called top quark in 1995. Its groundbreaking technology, meanwhile, helped pave the way for CERN's Large Hadron Collider, which will now pursue the one jewel missing from the Tevatron's resume -- the Higgs boson. Many experts contend that the collider could've gone on to achieve much more, but its ride will nonetheless come to an inglorious end at 2PM today, when Fermilab director Pier Oddone oversees the Tevatron's last rites. "That will be it," physicist Gregorio Bernardi told the Washington Post. "Then we'll have a big party."

  • CERN scientists discover particle traveling faster than the speed of light, Einstein theory threatened

    It ain't over till the LHC says so, which is why researchers at CERN are opening up their most recent OPERA experiment to the scientific community before officially releasing its findings. Why, you ask? Because the experiment could shatter one of the fundamentals of physics -- Einstein's theory of special relativity, which says nothing with mass can accelerate faster than the speed of light. While studying neutrino oscillations -- where particles shift from one type of subatomic particle (muon-neutrinos) to another (tau-neutrinos) -- scientists clocked a beam of muon-neutrinos outpacing the aforesaid ray of light by 60 nanoseconds. Calling the result "crazy," lead scientist Antonio Ereditato published the findings online, hoping to attract the attention of others who might shed some light on what it all means. We're not expecting a conclusive answer any time soon, but budding whiz-kids can get educated in the links below.

  • CERN's LHC@home 2.0 project simulates a Large Hadron Collider in the cloud

    "You break it, you bought it," came to mind when researchers at the Centre for European Nuclear Research (CERN) announced the LHC@home 2.0 project, giving us regular Joes access to the Large Hadron Collider. OK, we kid; the reality is that much like SETI@home and Folding@home, a whole group of volunteering home computers link up together, and while idle they quietly help simulate LHC particle collisions according to CERN's theoretical models. Scientists there then compare these results with those from actual LHC experiments in order to check for any instrumental or theoretical errors, thus potentially speeding up the mission to find the God particle in a low cost manner. Besides being a great way to get your science on, the cloud-based program also makes CERN's resources (like crisis mapping and damage assessment) available to researchers in developing nations that may not to be able to afford the accelerator's $6 billion dollar price tag -- but nowadays, what nation can?

  • Antimatter gets trapped for 15 minutes by CERN scientists, escapes unharmed

    Antimatter particles are elusive little critters that tend to disappear moments after being spotted. Unless, it turns out, you trap them in a "magnetic bottle" and turn the temperature right down to almost absolute zero. CERN scientists have now used this technique to hold 300 antihydrogen particles for up to 1,000 seconds, relaxing them into their ground (stationary) state to make them easier to study. This opens the way for further research later in the year, when captured particles will be prodded with lasers and microwaves to see if they obey the same laws of physics that govern everything else in our universe. After all this effort, we're quietly hoping they don't. [Thanks, Howard]

    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).

  • Large Hadron Collider smashes beam intensity record, inches closer to discovering God particle

    Already a record holder for mashing protons together at 7 TeV (trillion electron volts), the Large Hadron Collider can now add world's brightest beam to its list of accomplishments. Beam intensity is a way of measuring the number of collisions in its 17-mile-long track, and a higher intensity means more impacts -- which, in turn, means more data, increasing the likelihood that the elusive Higgs boson will rear its head (should such a thing exist). The LHC smashed the previous luminosity record set last year by the Tevatron collider. What's next for the CERN team, with two world records under its belt? Largest beard of bees.
