When Google asked what we'd do if we had Glass, it was no doubt hoping we'd produce some world-changing ideas. We now know at least a few exist, courtesy of physics teacher Andrew Vanden Heuvel. He's long been hoping to use the wearable tech for remote teaching and one-on-one sessions, and the Glass Explorer program has given him the chance to do just that. His first stop? None other than CERN. Courtesy of a trip for Google's new Explorer Story video series, Vanden Heuvel is the first person to teach a science course while inside the Large Hadron Collider tunnel, streaming his perspective to students thousands of miles away. While we don't know if other Explorer Stories will be quite as inspiring, we'll admit to being slightly jealous -- where was Glass when we were kids?

3D scanning at a range of 0.62 miles? It just became possible, thanks to a laser camera developed by physicists at Heriot Watt University in Edinburgh, UK. You can pretty much see how it works from the images above -- laser beams are bounced off the target and the duration of their return journey is measured precisely enough to detect millimeter depth changes even at extreme distances. Speaking of which, the researchers believe they could pump the range up to 10 miles with a bit of extra research, and even shrink the blaster down to make it "fully portable" in less than five years. Who knows, someday it might even work around corners. But there's a problem: skin doesn't reflect the beams properly, which means people can't be accurately scanned unless they also happen to be ringwraiths. As a result, the researchers seem slightly at loss as to what to do with the technology, with their best suggestions so far being watching the growth of foliage or tracking the movement of rocks. We'd try to think up some other ideas, were it not for the distracting and utterly irrelevant Nazgul v Wilhelm video embedded after the break.

Just because the PlayStation 4 centers around an AMD-based platform doesn't mean that NVIDIA is out of the picture. The graphics firm is updating the software developer kits for both its Apex dynamics framework and PhysX physics modeling system to address Sony's new console, even if they won't have the full hardware acceleration that comes with using NVIDIA's own chipsets. The introductions will mostly take some of the guesswork out of creating realistic-looking games -- theoretically, adding a larger number of collisions, destructible objects and subtler elements like cloth and hair modeling. Most of us won't see the fruits of the updated SDKs until at least this holiday, but programmers looking for more plausible PS4 game worlds can hit the source links.

We've long known that the Large Hadron Collider would need to take a break, but that doesn't take the edge off of the moment itself: as of Valentine's Day, the particle accelerator has conducted its last test for the next two years. The giant research ring will undergo sweeping repairs and upgrades that should should give it the superconducting connectors needed to hit the originally planned 14TeV of combined collision energy, versus the 8TeV it's been limited to almost since the beginning. CERN's machine arguably earned the downtime. After a rough start, it went on to produce rafts of collision data and healthy evidence of the elusive Higgs boson. If you're still down, think of the hiatus as doing us a favor -- it postpones any world-ending disasters until around 2015.

It's not often that researchers can verify a discovery that could change how we approach basic principles of technology, not just build on what we know. Nonetheless, MIT might have accomplished just such a feat in demonstrating a new state of magnetism. They've shown that a synthetically grown sample of herbertsmithite crystal (what you see above) behaves as a quantum spin liquid: a material where fractional quantum states produce a liquid-like flux in magnetic orientations, even if the material is solid. The behavior could let communications and storage take advantage of quantum entanglement, where particles can affect each other despite relatively long distances. MIT warns us that there's a wide gap between showing quantum spin liquids in action and developing a complete theory that makes them useful; we're not about to see Mass Effect's quantum entanglement communicator, if it's even possible. To us, realizing that there may be a wholly untapped resource is enough reward for now.

Teams at the Large Hadron Collider must be developing a knack for producing tangible evidence of theoretical particles. After orchestrating 2 million collisions between lead nuclei and protons, like the sort you see above, the collider's Compact Muon Solenoid group and researchers at MIT suspect that stray, linked pairs of gluon particles in the mix were signs of color-glass condensate, a currently theory-only form of matter that sees gluons travel in liquid-like, quantum-entangled waves. The clues aren't definitive, but they were also caught unexpectedly as part of a more routine collision run; the team is curious enough that it's looking for more evidence during weeks of similar tests in January. Any conclusive proof of the condensate would have an impact both on how we understand particle production in collisions as well as the ways gluons and quarks are arranged inside protons. If so, the CMS and MIT teams may well answer a raft of questions about subatomic physics while further justifying CERN's giant underground rings.

This week we're all over the place. Sorry about that, but it's all for the greater good. We start things off right down at the quantum level, then head to the oceans, before a quick jaunt into space before landing back deep inside your mind. All in the name of science, of course. Science and hip-hop that is. This is alt-week.

There are some questions that have puzzled the human race more or less since the dawn of time. Why are we here? What is the meaning of life? You know the sort of thing. While we might not have the answers to these just yet, thanks to science, we're getting there. In this week's instalment we discover that you can, in fact, smell fear. Meanwhile, one scientist pledges to launch an ambitious hunt for Bigfoot, and we get an early hint at what could be the start of an explanation for life, the universe and everything. This is alt-week.

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.

Sandia National Laboratories' Z machine sounds like it belongs in a James Bond movie more than it does an Alberquerque research facility. Based on what it can do, that's not as far-fetched as it seems. What you see isn't the handiwork of some electric spider -- it's what you witness in the immediate fraction of a second after the Z's electromagnetic pulse kicks in and forks of lightning burst across the 108-foot distance inside. The pulse in question is key to Sandia's studies of fusion and the effect of very intense magnetic pressures on materials that normally refuse to change states. Even in 2006, the Z was putting out pressure more than 10 million times that of the atmosphere, and it successfully melted diamond at roughly half that strength. It goes without saying that we don't want to be anywhere near this kind of energy when scientists flick the switch, but we're glad to see that something so pretty and deadly can help us understand physics.

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.

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.

Time to break out your theoretical physics cap for a moment. A new idea about the cause of neutron loss (a phenomena in which neutrons seem to momentarily disappear), is pushing the boundaries of easy to conceptualize science. Zurab Berezhiani and Fabrizio Nesti of Italy's University of l'Aquila have suggested that the particles could briefly be visiting parallel universes before returning. Experiments have shown that the rate of loss is dependent on the direction and strength of an applied magnetic field -- an anomaly that doesn't jibe with current physics. If a parallel universe existed consisting of so-called "mirror particles," however, the neutrons could temporarily swap places with its invisible twin before returning to its rightful place in this world. More experimentation is needed, but if the predictions of Berezhiani and Nesti are correct, it could indicate that we're surrounded by mirror particles in a parallel universe -- a potential culprit for the mystery of dark matter.

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.

Playback of 3D motion capture with a computer is nothing new, but how about with a solid levitating object? MIT's Media Lab has developed ZeroN, a large magnet and 3D actuator, which can fly an "interaction element" (aka ball bearing) and control its position in space. You can also bump it to and fro yourself, with everything scanned and recorded, and then have real-life, gravity-defying playback showing planetary motion or virtual cameras, for example. It might be impractical right now as a Minority Report-type object-based input device, but check the video after the break to see its awesome potential for 3D visualization.

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.

When most folks get ticketed for running a stop sign, most people wind up writing the court a check. UC San Diego physicist Dmitri Krioukov wrote a mathematical paper instead. Rather than throw his fallible human opinion on the mercy of the court, Krioukov uses a series of equations and graphs to prove that the accusing officer confused his car's real space-time trajectory "for a trajectory of a hypothetical object moving at approximately constant linear speed without stopping at the stop sign." In other words, the officer was wrong, but Krioukov stresses that it isn't the officer's fault. "This mistake is fully justified," he writes, pointing to the math. "As a result of this unfortunate coincidence, the O's perception of reality did not properly reflect reality." And to think, you probably never thought you'd use this kind of math in the real world.
