Laser-powered atomic clock fuels temporal pedants' ire
If you thought that your regular atomic clock, which loses a second once every few years, is adequate for your needs, then Dr. Jerome Lodewyck wants a word. His team at the Paris Observatory claims to have invented an atomic clock which only loses a second every three centuries. Rather than measuring the oscillations of caesium atoms, the "Optical Lattice Clock" uses a laser to excite strontium atoms which vibrate much faster and are, therefore, more accurate. Of course, it's a cruel irony that just as soon as someone's plonked down $78,000 on a Hoptroff No. 10, a rogue gang of scientists find a way to make it obsolete.
Hoptroff's atomic pocket watch is the ultimate rich guy accessory
So, you've made a fortune, bought a sports team, own a spaceship and drive a neon pink Batmobile. If you were worrying that there were no more extravagant purchases to be made, you were wrong. Luxury timepiece maker Hoptroff has just teased details of its latest method of parting you from your money -- a pocket watch with its own atomic clock. Unlike your average radio-receiving watch, the Hoptroff No. 10 will apparently contain a Symmetricom caesium gas chamber (pictured after the break), developed in partnership with the Department of Defense. The watch will be available in November and, if you get lost at sea with just a sextant, will double as a marine navigation device. Priced at £50,000 ($78,000), only twelve are to be produced, which you'll be able to buy provided you can pass the security checks necessary to carry "sensitive materials."
Sensitive scales can weigh individual atoms, ensure perfect recipes
Those of you who have navigated beyond using an Easy-Bake Oven will know that weighing out ingredients is a chore. Then again, it's nothing compared to the sort of balancing that takes place at the Catalan Institute of Nanotechnology, where a team has developed a method of weighing individual protons. Using heated, shortened carbon nanotubes in a vacuum, the scale vibrates at different frequencies depending on what molecules are balanced on top. The Yoctogram-scale will enable scientists to diagnose health conditions by finding differences in mass, identifying elements in chemical samples that only differ at the atomic level and ensuring you never over-flour your batter mix again.
New single ion clock is '100 times more precise' than existing atomic models
Researchers at the University of New South Wales have developed a new type of atomic clock that measures an atom's neutron orbit instead of the electron's flight path. This method is apparently accurate to 19 decimal places, with several lasers shifting electrons in a certain way, allowing Professor Victor Flambaum to measure the "pendulum" motion of the neutron. It's purportedly close to 100 times more precise than its predecessors -- all with no freezing involved. These existing atomic clocks may be accurate beyond 100 million years, but for this new breed of hyper-accurate timekeeping, you'll only need to reset the clock once every 14 billion years. And we have no idea how they calculated that.
Researchers capture first-ever images of atoms moving inside a molecule
The headline sums it up nicely but really, those photographic acrobatics account for only part of the story. Starting from the beginning, a research team led by Louis DiMauro of Ohio State University used an "ultrafast" laser to knock an electron out of its orbit, which scattered off the molecule as it fell back toward its natural path. That ripple effect you see in that photo up there represents any changes the molecule went through during the quadrillionth of a second that transpired between laser pulses. Yes, that's the kind of rare, psychedelic shot that's sure to earn DiMauro and team bragging rights, but the scientists also say this technique could have practical implications for observing -- and ultimately manipulating -- chemical reactions at an atomic level. Of course, it could be a long time yet before scientists analyze complex proteins in such detail: for the purposes of this experiment, the researchers stuck with simple nitrogen and oxygen molecules, with which chemistry scholars are already quite familiar. In fact, the researchers don't elaborate at all on specific studies where this technique might be useful, but you might want to hit up the source link nonetheless for some of the more technical details of how they pulled off this experiment in the first place.
This electric wire is four atoms thick, and you thought speaker cable was fiddly (video)
This should come as a great relief to anyone planning a quantum computer self-build: wires still conduct electricity and obey key laws of classical physics even when they're built at the nanoscale. Researchers at Purdue and Melbourne universities used chains of phosphorus atoms inside a silicon crystal to create a wire that's just four atoms wide and a single atom high -- 20 times smaller than the previous record-holder and infinitely narrower than anything you'd find at Newegg. The video after the break almost explains how they did it.
Nuclear clocks could be 60x as accurate as atomic counterparts, less prone to errors
For years, atomic clocks have been considered the most accurate devices for tracking the slow march towards obsolescence, a subatomic particle vibrating a given number of times per second with relatively few issues. Now the reliability crown might be passed to the nuclear clock, which in addition to sounding gnarly, could prove to be less susceptible to errors from outside stimuli. It goes like this: although an atomic clock will measure a certain number of vibrations per second, external forces such as ambient electric and magnetic fields affect the electrons used in atomic clocks, causing mishaps. The particles used in nuclear clocks that are measured for vibrations -- and thus timekeeping -- can be excited with a relatively low-energy ultraviolet light, allowing for fewer variations from the aforementioned fields. To wit, Corey Campbell and colleagues at the Georgia Institute of Technology in Atlanta have devised a scheme that uses lasers to carefully control the spatial orientation of the electron orbits in atoms. A nuclear clock containing a thorium nucleus controlled in this way would drift by just one second in 200 billion years, the team claims. Before nuclear clocks become a reality, researchers must identify the precise frequency of light needed to excite thorium nuclei; but this is what grad students are for, right?

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."
Large Hadron Collider breaks energy record, still won't power a toaster
CERN's Large Hadron Collider just made the record books for something other than the cost of building a 27km-long circular tunnel. After achieving its first collision on Tuesday, the LHC roared beyond a trillion electron volts (1.18 TeV to be exact) literally smashing the 0.98 TeV energy record held by the Tevatron particle accelerator in Chicago since 2001. So far the LHC had been operating at a relatively modest 450 billion electron volts as it pushes up to full capacity of some 7 trillion electron volts. All that's left now is the minor issue of unlocking the secrets of the universe when the real scientific testing gets underway early next year.
Atomic Zune HD explodes all over Ebay
Hey, remember that totally wild, awesome looking "Atomic" Zune HD we spied evidence of in the source files a week or so ago? Well, we later saw an image or two of it, but now one's shown up in the flesh on ebay -- and for a starting bid of a mere 265 bones you might be able to snag it! This one's a 32GB model, and while we still don't know if it's going to be officially released or not, we get the feeling that it probably will. Regardless, we'd advise starting a bidding war anyway. Oh, and we're totally winning this one so hands off.[Via Anything but iPod]
New Zune HD colors found in source files: pink, magenta, purple, and atomic
Well, here's something interesting. According to tipster Josh S, a perusal through the Zune Software source files will net you pictures of four as of yet unknown Zune HD palettes. From left to right, we've got pink, magenta, purple, and "atomic." We're still looking through the source code ourselves to confirm. It's not like early adopters wanted anything other than platinum and black anyway, right?Update: We've finally come up from digging through source code and, sure enough, those images are all in there.
Atomic Games unable to secure funding for Six Days in Fallujah, reduces staff
(click to embiggen) Citing a lack of "full-scale funding" for controversial game Six Days in Fallujah, Atomic Games is reporting today that it's trimming staff. According to Atomic, the 75 employees of the studio remained until this week when an undisclosed amount were let go. Though the developer assures the "dozens of Marine veterans" who have spent "hundreds of hours in this project" that it will "fight on," we worry that this is just one more sign of a likely to-be-canceled game. After Konami dropped out as the game's publisher back in April, Six Days in Fallujah's fate has been up in the air. It probably doesn't help that rumors circulated yesterday about the studio's creative lead hitting the road for (presumably) greener pastures. We've reached out to Atomic for further information about those let who were let go and will update this post as we hear more.%Gallery-49389%
Are all MMOs just extended vaporware?
Massively multiplayer online games can be a difficult industry to break into and succeed. For every Blizzard or Sony Online Entertainment, there are several smaller companies brimming with ideas about how to inject change into the MMO market. Some succeed by breaking from the World of Warcraft paradigm. Most do not. Writer James Matson writes about these titles that begin full of promise but ultimately meet a chilly reception by MMO gamers, in an article at Atomic. He touches on the fact that the sometimes high price of the box sale paired with monthly MMO fees, sustained over some months, leads to some serious disappointment when the MMO fails and the servers go dark. Matson specifically cites the examples of Auran's Fury and (what is currently Namco-Bandai's) Hellgate: London. "This would appear to the be the first tendrils of a new kind of gaming plague that's arrived with MMOs, games that can be rendered useless due to mismanagement, poor sales or just bad luck," Matson writes.
Antelope Audio's atomic master clocker helps keep the beat
While Engadget is no stranger to wacky clocks and even the occasional atomic goofiness, this is the first time we've seen them combined with a promise to make your musical creations sound better - but that's exactly what clock-obsessed Antelope Audio is claiming with its new Isochrone 10M atomic master clocker. Although most pro studios already rely on external clocks to keep all their gear marching to the same beat, Antelope claims that its rubidium-powered baby is 100,000 times more stable than traditional crystal oscillator clocks, an upgrade that'll allow you to pump out the jams for up to eight days without missing a step. No deets on pricing or availability, but Antelope says that the 10M is the first "affordable" atomic clocker, so we'll see what they think that means when this thing drops.[Via MusicThing]
Atomic "transistor" proposed using quantum cloud material
Intel might be oh-so-smug about its fancy new insulators and 45nm process, but doesn't have nothing on these upcoming atomic transistor dealios -- other than that whole "shipping" thing, of course. Scientists working at the Worcester Polytechnic Institute in Massachusetts and compadres at the University of Colorado Boulder have proposed implementing a "Bose-Einstein condensate" to pull this off -- a super-cold gas cloud of atoms all in the same quantum state -- which is manipulated with three adjacent chambers that are created by trapping atoms with magnets or laz0rs. By swapping atoms between the two side chambers, and controlling that action with the center chamber, a behavior is created similar to that of an electronic field-effect transistor. Which is apparently a good thing. So yeah, the tech definitely flies over our heads, but if this works it sounds like it's a pretty big breakthrough in building atomic "circuits" some day by connecting basic atom elements and should hopefully keep Moore's law alive and well a few decades down the road.[Thanks, Jeremy]
