Korean geniuses invent lithium batteries with eight times the juice

Oh, what wondrous things come from the land of Korea -- dancing emotional robot humanoids, oxygen-emitting robot plants, and multiple 24-hour StarCraft channels. It's all good, and we dig robotics and televised gaming, but this latest invention could be our favorite if it pans out. Professor Cho Jae-Phil and his team at Hanyang University have replaced the graphite in lithium batteries with a certain kind of silicon, which we're told can store eight times the power. No word on what the batteries have actually been used for yet, but it stands to reason they could eventually make it to consumer electronics. Now you see why we're willing to say this might be better than 24-hour StarCraft. Say it with us: 48-hour StarCraft.

Flying plasmonic lens system could lead to denser chips / disks


Last we heard, IBM was busy extending optical lithography down to 30-nanometers in order to keep Moore's Law intact, and some two years later, the process is still being honed by engineers at the University of California, Berkeley. Reportedly, gurus there with IQs far greater than ours have developed a new patterning technique (plasmonic nanolithography) that could make "current microprocessors more than 10 times smaller, but far more powerful." Additionally, professor Xiang Zhang asserts that this same technology could eventually "lead to ultra-high density disks that could hold 10 to 100 times more data than disks today." The secret to the madness is a flying plasmonic head, which is compared to the arm and stylus of an LP turntable; the setup enables researchers to "create line patterns only 80-nanometers wide at speeds up to 12-meters per second, with the potential for higher resolution detail in the near future." In layman's terms? That CPU you purchased last month will, in fact, be old hat in due time.

Black silicon is poised to improve digital imaging, maybe solar panels


We're big fans of silicon, but it turns out the stuff has been slacking off, and all it needs is a little nudge from sulfur hexafluoride and a high-powered laser to start working harder. When it gets that nudge it becomes a new material called black silicon that's between 100 and 500 times more sensitive to light -- including, amazingly, infrared. Some of the folks who accidentally invented black silicon started a company called SiOnyx, and with $11 million in venture financing, they're trying to commercialize it -- first for night vision and later for digital cameras, medical imaging, and maybe even solar cells. The benefits are obvious, but like a lot of other future miracle technologies we've heard about, it's still just science fiction to consumers until a solid deal is struck to bring it to market.

Another breakthrough purportedly brings us closer to quantum computing


In reality, quite a bit of time has passed since we've heard of the next great leap in the (seemingly) never-ending journey towards quantum computing, but we're incredibly relieved to learn that at least someone is still out there, somewhere, pressing on. An international team of researchers have reportedly shown that they can "control the quantum state of a single electron in a silicon transistor, even putting the electron in two places at once." Essentially, the team is using tiny semiconductor transistors to "control the state of a quantum system," but there is still a long ways to go before any of this is meaningful. The crew managed to discover a few things by chance, yet to create a quantum computer, they would need to "position atoms of arsenic (or some other material) in the transistors more reliably." For those of you way too geeked out, fret not -- we'll let you know when all of this technobabble finally amounts to something.

CNRS learns to control nanoscale strain in CPUs, heads to Jedi training

We've always heard that Chewbacca and friends had the power to control nanoscale strain in processors in a galaxy far, far away, but we Earthlings are just now getting caught up. Researchers at the Centre d'élaboration de matériaux et d'études structurales (CEMES-CNRS) have reportedly patented a measurement device that will essentially "enable manufacturers to improve microprocessor production methods and optimize future computers." We'll warn you, the meat of this stuff is pretty technical, but the take home is this: the technique has a good chance at "optimizing strain modeling in transistors and enhancing their electrical efficiency," which is just what we need for more potent chips that demand less energy. And that's something even a layman can appreciate.

Silicon wafer directs and filters out cancer cells

CellsNormally we get excited when a slab of silicon makes our games run at 60 frames per-second, but in this case we're impressed with a new chip that filters out cancer cells. The device, created by some impressive souls at Princeton and Boston University, directs and focuses streams of cells in a liquid. Like a change sorter, it then separates regular cells form unusual ones. The silicon wafer is tacked with tiny pillars that catch abnormal cells that are, in the end, potentially cancerous. The device hasn't been used to any major extent, but we'll keep an eye on this promising discovery.

Stretchy silicon circuits wrap around complex shapes, like your wife


The first "completely integrated, extremely bendable circuit" was just demonstrated to the world. The team behind the research is led by John Rogers of the University of Illinois at Urbana-Champaign. The process bonds circuit sheets measuring just 1.5 micrometers (50 times thinner than human hair) to a piece of pre-stretched rubber. That allows the circuits to buckle like an accordion when pulled or twisted without losing their electrical properties. Unfortunately, the materials used thus far are not compatible with human tissue. In other words, no X-ray vision implant for you. X-ray contacts perhaps... quantum-computers now, please Mr. Scientists? Watch a circuit buckle in the video after the break.

IBM develops greener method for recycling silicon

IBM is looking to save around $1.5 million per year and be a kinder citizen to the environment by instituting a greener method for recycling silicon. Previously, IBM would sandblast defunct wafers to make sure no trade secrets left the premises when they were sold off to solar-panel outfits or used as "monitors." The new process, however, involves defacing the circuitry with an abrasive pad and water, which saves a few bills and leaves the silicon in much better shape for reuse. Reportedly, Big Blue has already implemented the new approach in its Essex Junction, Vermont facility, and the East Fishkill, New York plant is all set to follow suit shortly.

NC State researchers uncover muscle mimicking fibers

While some researchers over in Raleigh are having fun tinkering with PlayStation 3 farms and dodging the RIAA, NC State's Drs. Tushar Ghosh and John Muth are occupied building prototypes with fibers they say "resemble human muscle and can exhibit muscle-like capabilities when electrical currents are applied." The duo sees the development as paving the way for "advancements and potential applications in robotics, smart textiles, prosthetics, and biomedicines," as they have reportedly found that polyurethane and silicone tube structures shaped like human muscle strands can be manipulated with electricity. It was noted, however, that the current models are using strands "roughly the size of a pencil lead," but the next step is to scale down the fibers and integrate them into a robotic Mr. and Mrs. Wuf.

MIT researchers cram optical circuitry on a silicon chip

It looks like MIT is raising the bar yet again, as this time it's taking a break from crafting autonomous UAVs and stackable vehicles to cram optical circuitry on your everyday silicon chip. In an effort to "integrate the optical circuitry with electronic circuitry" on the same silicon wafer, researchers have devised a method which will harness the "enormous power of light waves in networks" while offering up a way to manufacture the circuitry cheaply. The crew has reportedly already been playing around with a working prototype, and suggests that it could eventually "redefine how optical networks are built." Moreover, the development addresses the existing "signal weakening over distance" issue in fiber optic transmissions by "splitting the light beams as they pass through a circuit, rotating one of the polarized beams, and finally rejoining them on their way out of the circuit, which retains the signals' strength." While there's no projection of when this technology could actually hit the mainstream, anything that makes it less expensive to rollout FiOS (and similar networks) to more people most definitely has our vote.

California crooks nab 100,000 microchips

Proving that Malaysian industrial complexes aren't the only venues where shoddy security can facilitate the theft of thousands of PC components, a pair of crooks in California turned a minor fender bender into a successful heist of some 100,000 microchips on Tuesday afternoon. Police suspect that the men had been planning the crime for some time, as the victim's Fremont-bound Mazda MPV had just left a warehouse with $190,000 worth of chips when the robbers rear-ended it with their white van; rather than using weapons to subdue the driver, however, the two thieves simply waited until he exited the vehicle to discuss the accident, when one of them proceeded to slip into the minivan and drive away. The driver of the van followed suit, leaving the victim standing on the side of the road, no doubt confused and worried that his employer would chew him out for being so careless with the precious cargo. Although the brand of chip has not been revealed, since this all went down in Santa Clara, it's not too difficult to figure out whose products got pinched. So far authorities have no leads as to the whereabouts of the chips or the two robbers, but if someone in an MPV with license plate 4NKV115 tries to sell you a CPU for a buck and some change, do the right thing and notify law enforcement officials after you've purchased enough silicon to meet your needs. And if you're driving back home with your cheap booty when someone happens to ram your car, for heaven's sake, don't leave the keys in the ignition when you get out to exchange insurance info.

AMD shows off Barcelona server chips, garners mixed reviews

With Intel giving its shareholders some awfully great news to savor over the holidays, AMD had to hit back with some news of its own, but you'll definitely get a different vibe from reading ExtremeTech's take on the firm's recently showcased Barcelona than from the horse's own mouth. While AMD parades its 65nm chip as "the world's first native quad-core x86 server processor," and boasts about its "significant advancements in performance per watt capabilities," we've reason to wonder if things aren't a bit sugarcoated. While the wafer was demonstrated as utilizing "all 16 cores" and being a seamless upgrade from "dual-core to quad-core", hard facts (read: the much anticipated benchmarks) were curiously absent. Aside from injecting onlookers with more of the same technical minutiae we've seen over the past few months, AMD didn't exactly flesh out a lot of new details to chew on, but ExtremeTech's reference system "was the loudest they'd ever had in their office," and sucked down nearly 600 watts of power with just two HDDs and a single graphics card. So while we're firmly withholding judgment until its officially released, we'd say AMD still has a bit of tweaking to do before the competition rolls in.

UPDATE:
Looks like we mistook the quad-core Opteron and the Quad FX (announced on the same day, nonetheless) chips as one in the same, when (thankfully) they're not, but those eying the recently-released FX-based desktops may want to think about how much noise they're willing to put up with before throwing down on a new machine.

Group IV Semiconductor unveils plans for silicon lighting

For those out there just looking for zanier methods to get your illumination on, Group IV Semiconductor is hoping to deliver the goods you crave. While about 60 percent of the world's artificial lighting is still derived from the incredibly inefficient incandescent variety, companies like Philips are offering up LED alternatives that conserve energy, emit less heat, and convert perfectly normal buildings into nerdish eye candy. The Ottawa startup has spent its last four years researching and developing a silicon-based lighting system that will hopefully be "just as cheap" to produce as solid-state alternatives and emit equivalent amounts of light to boot. To overcome one of silicon's less helpful characteristics (poor light emission, of all things), the company has packed nanocrystals -- otherwise known as "quantum dots" -- between a transparent layer in which current is directed and a substrate of silicon underneath. Once electricity is applied, the nanocrystals settle back into their natural state, give off photons, and create a low-heat form of light roughly equivalent to a standard 100 watt light bulb. Group IV is aiming to produce a product that requires "90 percent" less energy than options currently on the market, while building it to last "50 times" longer than the already longevous alternatives, so you should probably expect this (presumably) once in a lifetime purchase to demand quite a premium should it actually hit store shelves.

Intel embedding lasers into silicon for speedy data

In what's being marked as a breakthrough in the world of "photonics," Intel has managed to squeeze laser beam functionality into silicon-based chips, allowing for high speed data transfer between chips on the cheap. The new technology should be a boon to both high-end computer manufacturers and the fiber-optics industry, allowing for cheaper, smaller and faster optical switching of high volumes of data. Intel managed the feat by bonding some light-emitting indium phosphide to the surface of a regular ol' silicon chip that has been etched with light-directing channels. With billions of lasers in one place, the chips should help with the "last mile" problem of bringing fiber to the home, and resolve most bandwidth bottlenecks inside your computer -- though that type of consumer application could be quite a few years down the road. Commercial versions of the chips are still years away, but we're liking where this is headed.

Self-healing chips could function forever

Although you may have never given a thought to what transistors do to repair themselves when certain sectors fail, there are a few organizations who make it their life's work. Researchers from the National Science Foundation, the Semiconductor Research Corporation, and the University of Michigan have a mission to complete before their grant money runs dry: to create semiconductors that can heal themselves without the burdensome redundancy currently used. The goal here, which could seem a tad superfluous until you consider these chips operate in things like airplanes and medical devices -- you know, fairly critical applications -- is to design a semiconductor that runs more efficiently and can be counted on to function no matter how crucial the situation. By designing a chip that can auto-detect a problem, then shift the resources to a functioning area while the chip diagnoses and repairs the issue with help from "online collaboration software," you'll get a slimmer semiconductor that suffers no noticeable loss in performance while self-repairing. If this circuitry talk has your wires all crossed up, here's the skinny: more dependable chips will make everyone's life a bit easier, and if the team's plan is free of defects, we can expect to see prototypes within the next three years.
