Ready to get swept away into the wild, wild abyss known as quantum computing? If not, we're certain there's a less mentally taxing post above or below, but for those who answered the call, researchers at the University of California Santa Cruz have a doozie to share. A team of whiz kids at the institution have developed a minuscule optical device that's built into a silicon chip, and it's capable of reducing the speed of light by a factor of 1,200. If you're wondering why on Earth humans would be interested in doing such a thing, here's the long and short of it: the ability to control light pulses on an integrated chip-based platform "is a major step toward the realization of all-optical quantum communication networks, with potentially vast improvements in ultra-low-power performance." Today, data transmitted along optical fibers must still eventually be converted to electronic signals before they're finally understood, but the promise of an all-optical data processing system could obviously reduce inefficiencies and create communication networks that are far quicker and more robust. There's still no telling how far we are from this becoming a reality -- after all, we've been hearing similar since at least 2006 -- but at least these folks seem to be onto something good... even if it's all too familiar.All-optical quantum communication networks nearly realized, 'Answers to Life' airing at 9PM originally appeared on Engadget on Tue, 07 Sep 2010 23:04:00 EDT.

Researchers turn to 19th century math for wireless data center breakthrough
Researchers from Microsoft and Cornell University want to remove the tangles of cables from data centers. It's no small feat. With thousands of machines that need every bit of bandwidth available WiFi certainly isn't an option. To solve the issue, scientists are turning to two sources: the cutting edge of 60GHz networking and the 19th century mathematical theories of Arthur Cayley. Cayley's 1889 paper, On the Theory of Groups, was used to guide their method for connecting servers in the most efficient and fault tolerant way possible. The findings will be presented in a paper later this month, but it won't be clear how effectively this research can be applied to an actual data center until someone funds a prototype. The proposed Cayley data centers would rely on cylindrical server racks that have transceivers both inside and outside the tubes of machines, allowing them to pass data both among and between racks with (hopefully) minimal interference. Since the new design would do away with traditional network switches and cables, researchers believe they may eventually cost less than current designs and will draw less power. And will do so while still streaming data at 10 gigabits per second -- far faster than WiGig, which also makes use of 60GHz spectrum. To read the paper in its entirety check out the source.Filed under: Wireless, Networking, Science, Alt, MicrosoftResearchers turn to 19th century math for wireless data center breakthrough originally appeared on Engadget on Fri, 12 Oct 2012 11:39:00 EDT.

Researchers create spinal cord connectors from human stem cells, heralding breakthrough
It's taken many years and more than a bit of brainpower, but researchers at the University of Central Florida have finally found a way to create neuromuscular connectors between muscle and spinal cord cells, using only stem cells. Led by bioengineer James Hickman, the team pulled off the feat with help from Brown University Professor Emeritus Herman Vandenburgh, who collected muscle stem cell samples from adult volunteers. After close examination, they then discovered that under the right conditions, these samples could be combined with spinal cord cells to form connectors, or neuromuscular junctions, which the brain uses to control the body's muscles. UCF's engineers say the technique, described in the December issue of the journal Biomaterials, marks a major breakthrough for the development of "human-on-a-chip" models -- systems that simulate organ functions and have the potential to drastically accelerate medical research and drug development. These junctions could also pay dividends for research on Lou Gehrig's disease or spinal cord injuries, though it remains unclear whether we can expect to see these benefits anytime soon.Researchers create spinal cord connectors from human stem cells, heralding breakthrough originally appeared on Engadget on Wed, 23 Nov 2011 10:03:00 EDT.

Wouldn't it be neat if you could power a few gadgets around the house with some tastefully chosen, solar cell-embedded curtains? Alright, so this MIT-pioneered tech's not quite that advanced yet, but it's destined to have a Martha Stewart Living future. By eschewing liquids and high temperatures for gentler vapors kept below 120 degrees Celsius, researchers were able to cheaply print an array of photovoltaic cells on "ordinary untreated paper, cloth or plastic." And here's some additional food for thought -- the vapor-deposition process used to create these cells is the same as the one that puts that "silvery lining in your bag of potato chips" -- science, it's everywhere. Despite the tech's home furnishing friendly approach, this breakthrough printing technique can't be done with your everyday inkjet, but it will make the cost of solar energy installations a bit cozier. Its flexible durability aside, the cells currently operate at only one percent efficiency -- so you might want to buy those drapes in bulk to see a real bottom line kickback. Foldable paper video demonstration after the break.Continue reading MIT researchers revolutionize solar cell printing, fold the power of the sun into your everyday home (video)MIT researchers revolutionize solar cell printing, fold the power of the sun into your everyday home (video) originally appeared on Engadget on Tue, 12 Jul 2011 23:54:00 EDT.

Ditching DRM could reduce piracy, prices, inconvenience
This may run counter to what your common sense tells you but, a new paper out of Duke and Rice University says that ditching DRM could actually reduce piracy. The study, which relied on analytical modeling, showed that while copy protection made illegally sharing content more difficult it had a significantly negative impact on legal users. In fact, the researchers say, "only the legal users pay the price and suffer from the restrictions [of DRM]." Many consumers simply choose to pirate music and movies because doing simple things, like backing up a media collection, is difficult with DRMed content. Even the most effective DRM is eventually broken, and fails to deter those already determined to steal. Meanwhile, abandoning these restrictions could increase competition and drive down prices (as well as remove a serious inconvenience), encouraging more people to legitimately purchase content. You can check out the November-December issue of Marketing Science for more details.Ditching DRM could reduce piracy, prices, inconvenience originally appeared on Engadget on Sun, 09 Oct 2011 20:22:00 EDT.

Liquid solar cells are pretty neat, to be sure, but current-generating paint can be a hard color to match. Good thing, then, that researchers at Rice university have developed the perfect complement: a spray-on battery. By carefully layering five coats of specially formulated paint, the team has found a way to apply a thin coat of lithium ion storage to multiple surfaces, including glass, ceramics, steel and flexible polymers. Early experiments are promising -- after applying the process to nine ordinary bathroom tiles, the painted batteries were able to power a small array of LEDs (spelling "Rice") for six hours, consistently pumping out 2.4 volts of electricity. After 60 charge / discharge cycles, researches say the batteries retained most of their capacity. Neelam Singh, Rice graduate student and lead author of the team's report, says the technology will only improve when coupled with modern methods. "Spray painting is already an industrial process, so it will be very easy to incorporate this into industry," she said. "We really do consider this a paradigm changer." Scope out the processes (and its fruits) for yourself after the break.Continue reading Rice University researchers create spray-on battery, powered bathroom tilesRice University researchers create spray-on battery, powered bathroom tiles originally appeared on Engadget on Fri, 29 Jun 2012 01:29:00 EDT.

EPFL mixes graphene and molybdenite to make very efficient, flexible flash memory
We've seen graphene chips, and we've seen molybdenite chips. What would happen if we combined the two? If EPFL's experimental flash memory is any clue, we might get one of the better blends since chocolate met peanut butter. The chip uses graphene's high conductivity for the memory itself, as well as for electrodes, but stuffs molybdenite in between to rapidly switch electrical states (such as what you'd see in write commands) while using little power. The hybrid is theoretically both faster and more power-efficient than conventional silicon designs, but that's just the start: the extra-thin nature of either material is better-suited to flexible electronics on top of shrinking the chip footprint. If there's anything at this stage that would sour EPFL's dreams of a storage utopia, it's time. There's no immediate mention of commercialization plans for the mutant memory, which could leave us stuck on silicon for awhile.Filed under: Storage, ScienceCommentsSource: ACS Nano

A new generation of cheaper, passively powered smart tags could accelerate NFC adoption very soon. Developed at Sunchon National University and Paru Printed Electronics Research Institute in Korea, the circuits could be printed in a similar method to newspapers, but it's the inclusion of the rectenna that makes the new chip technology so appealing. The combination antenna and rectifier can pick up residual radio waves from your phone to power itself. This new technology could apparently drop the cost of installing NFC to as little as one penny per unit, while offering up additional two-way functionality over its RFID rival. And if there's a speed boost in the process, well, all the better.Filed under: Misc.

Scientists improve blue OLED efficiency, don't promise everlasting light
Although this is not the first time we've seen an efficiency increase in blue OLEDs, it's worth noting that their proposed cap of productivity up to this point was a lowly five percent. It's exciting to learn, therefore, about a breakthrough by professor John Kieffer and graduate student Changgua Zhen from the University of Michigan, which has resulted in them successfully increasing azure diode power efficiency by 100 percent. The duo, accompanied by some bright minds in Singapore, manipulated performance controllers by rearranging OLED molecules in a computer model, improving material characteristics. In simple terms though, we're still looking at a measly ten percent efficiency, so we'll see where they take it from here.Scientists improve blue OLED efficiency, don't promise everlasting light originally appeared on Engadget on Sat, 26 Mar 2011 20:08:00 EDT.
