Stanford researchers manage to put a particle accelerator on a silicon chip

In scientific pursuits, like the search for dark matter, researchers sometimes use high-power particle accelerators. But these giant machines are extremely expensive and only a handful of them exist, so teams must travel to places like the SLAC Natio...

Exotic Hadron Particles Discovered


The fact has been affirmed without a shadow of doubt that hadron particles exist. And these strangely different forms of infinitely small matter do not conform to the standard manmade version of...

Primed: The smashing science behind particle accelerators

The smashing science behind particle accelerators

Long before the Large Hadron Collider (LHC) could smash its first atoms, researchers manning the Tevatron collider at Fermilab, in a quiet suburb 40 miles west of Chicago, raced to find evidence that the Higgs boson exists. After roughly three decades of service, the Tevatron shut down for good in late 2011, dealing the city of Batavia's largest employer a significant blow. Less than 18 months later, the LHC (the Tevatron's technological successor) also went offline - albeit temporarily. Only four years after recording its first proton collisions, the team at CERN is already scrambling to upgrade the staggering LHC, which lies under parts of no less than five cities in both France and Switzerland. With the world's largest particle colliders smashing a whole lot of nothing together for the next two years at least, the field of high-energy physics research is starting to look resource-starved. Of course, many might ask why exactly we need giant atom smashers like this, or even how they work. It turns out that first part is quite a bit easier to answer than the second.

During the last several decades, particle accelerators have revealed the existence of elementary particles such as quarks, led to the discovery of antimatter and generally helped us unlock the mysteries of the universe. And once they were done splitting atoms and probing the darkest corners of theoretical physics, accelerators often led to breakthroughs in medical imaging and cancer research. So, as massive colliders seem ready to land on the endangered species list, it seems as good a time as any to explain what a particle collider is, how it works and what we as a society have to gain from the research.

Rovio and CERN teaming up on education: hopefully the Angry Birds help us this time

Rovio and CERN teaming up on education hopefully the Angry Birds help us this time

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.

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

CERN confirms existence of new particle consistent with Higgs boson

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. Check out the more coverage link for a helpful FAQ about everything Higgs.

CERN update on its search for Higgs boson starts at 3AM ET (video)

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

Higgs boson just may, possibly, more or less be proven 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.

Researchers Produce Temperature of 7.2 Trillion Degrees, Set “World’s Hottest” Record

It’s summer in Texas, and I’ve lived here my entire life. That means I know a thing or two about hot. A group of physicists at the Brookhaven National Laboratory has landed themselves in the Guinness Book of World Records for creating a temperature that makes a Texas summer sound like winter in the Arctic Circle.

rhic

The physicists created the highest man-made temperature in history at 7.2 trillion degrees Fahrenheit. The researchers were able to produce such a massive temperature only for a fraction of a second using the Relativistic Heavy Ion Collider at the lab. The physicists sent gold ions flying in opposite directions around the 2.4-mile collider at a velocity near the speed of light.

The gold ions collided inside one of the six test chambers and the collision produced a substance known as quark-gluon plasma. This is described as a nearly frictionless liquid is about 250,000 times hotter than the core of the sun. It still feels hot here in Texas, regardless.

Large Hadron Collider affected by full moon, ocean commiserates

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.

CERN scientists explain what would happen if you put your hand in the LHC’s beam (video)

CERN scientists explain what would happen if you put your hand in the LHC's beam (video)

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.
