An anonymous reader writes "A novel transistor architecture has been developed by a team of researchers led by Jean-Pierre Colinge at Tyndall National Institute at Cork, Ireland. Not many technology developments can be truly described as 'a breakthrough' or "revolutionary' but this might just fit the bill. It does depend on the extremely small dimensions of silicon nanowires just a few dozens of atoms wide. EE Times picked up on an announcement of a paper on the topic being published by Nature Nanotechnology."

rwiggers writes "AMD has released two new low power processors for embedded apps. With a power of 18W and a chipset with 3W of average consumption [PDF] it seems we may have some interesting competition with Intel's Atom."

FullBandwidth writes "Paper-thin batteries that can be printed onto greeting cards or other flexible substrates have been demonstrated at Fraunhofer Research Institution for Electronic Nano Systems in Germany. The batteries have a relatively short life span, as the anode and cathode materials dissipate over time. However, they contain no hazardous materials."

Charbax writes "At Computex in Taipei on June 2-6th, several companies unveiled ARM-powered laptops that are cheaper ($99 to $199), last much longer on a regular 3-cell battery (8-15 hours) and can still add cool new features such as a built-in HDMI 720p or 1080p output, 3D acceleration, connected standby and more. The ARM Linux laptops shown as working prototypes at Computex will run Ubuntu 9.10 (optimized for ARM), Google Android, Xandros OS for ARM, or some Red Flag Linux type of OS. In this video, the Director of Mobile Computing at ARM, is giving us all the latest details on the status for the support of full Flash (with all actionscripts), the optimizations of the web browser (accelerating rendering/scrolling using the GPU/DSP), the stuff that Google is working on to adapt Android 2.0 Donut release for laptop screens and interfaces and more. At Computex I also filmed an interview with the Nvidia team working on Tegra laptops, the Qualcomm people working on Snapdragon devices and the Freescale people doing their awesomely thin ARM laptops in cooperation with manufacturers such as Pegatron as well."

An anonymous reader writes "A new category of 3-D motion controller for gamers uses a novel type of micro-electro-mechanical system (MEMS) gyroscope to track hand motions with unparalleled accuracy. By detecting the natural motions made by remote control users — as opposed to the unnatural motions that gamers must learn to control today — the MEMS chip is sure to be incorporated in both game consoles and other consumer electronics like TV remote controls. Nintendo has already incorporated a similar MEMS gyro into its forthcoming MotionPlus controller for the Wii, but this newer type of gyroscopic motion sensor will enable even more intuitive and agile control."

An anonymous reader writes "By harnessing the shells of living organisms in the sea, microscopic algae called diatoms, engineers have tripled the efficiency of experimental dye-sensitized solar cells. The diatoms were fed a diet of titanium dioxide, the main ingredient for thin film solar cells, instead of their usual meal which is silica (silicon dioxide). As a result, their shells became photovoltaic when coated with dyes. The result is a thin-film dye-sensitized solar cell that is three times more efficient than those without the diatoms."

An anonymous reader writes "Intel has developed a device, the Avalanche Photodetector, that senses light pulses and amplifies output signals for faster data transfer over long distances. Researchers claim this is a big advancement in the field of silicon photonics, in which silicon is used to transfer light pulses for data exchange between chips and devices. APD can detect light at higher frequencies and moves data at rates of 40Gbps, making it more sensitive and quicker than earlier photodetectors, at a tenth the cost."

Eukariote writes "An estimated 18 million laptops with NVidia G84 and G86 graphics chips sold in the past one and a half years are experiencing high failure rates. Various laptop models from multiple manufacturers (Apple, Dell, HP, Lenovo, and others) are affected. NVidia blames it on bad chip packaging causing thermal failure. BIOS updates that turn the laptop fan on more frequently or permanently have been released by Dell and HP. The cynical interpretation is that this is likely to only delay the problem until the warranty has expired."

phorm writes "Reuters is carrying an article about a recent MIT development which may pave the way for solar-energy to be collected for use in low-input periods. According to Reuters, the discovery of the a new catalyst for separating hydrogen+oxygen from water requires only 10% of the electricity of current methods. This would allow storage-cells to function as a form of battery for other forms of energy-collection, such as solar panels. The new method is also much safer (and likely environmentally friendly) than current methods, which require the use of a dangerously caustic environment, and specialized storage containers." sanjosanjo points out coverage of the process at EE Times, which features the MIT group's press release.

DeviceGuru writes "Caltech claims its researchers have 'turned science fiction into reality' with their development of a single-chip microscope. Although it doesn't have any lenses, the device is said to provide magnification comparable to that of sophisticated optical microscopes. The microscope's magnifying capabilities derive from a technology known as microfluidics, which is based on the channeling of fluid flow at incredibly small scales. Applications for the so-called 'optofluidic microscope' are expected to include field analysis of blood samples for malaria, or checking water supplies for giardia and other pathogens. The project's director thinks devices based on it could be implanted directly into the human body, in order to help arrest the spread of cancer." There's also coverage of the microscope at EE Times.

An anonymous reader writes "Researchers at Harvard University and Hamamatsu Photonics have found a way to collimate lasers without lenses. In the new 'plasmonic collimator' technique, grooves are etched directly into the semiconductor laser's internal mirror. This results in surface plasmons giving rise to constructive interference, eliminating the need for the bulky optical lenses that usually focus the light from semiconductor lasers. The technique has promise for steering laser beams without moving parts and for working with polarized light."

An anonymous reader writes "California is burning, but according to this article advanced sensors on NASA's Ikhana unmanned aerial vehicle (UAV) can detect exact temperatures (within half a degree) through the smoke, enabling the drone to spot for the firefighters battling the more than 300 wildfires. NASA's Ikhana is the same aircraft as the Predator, except it's being used here to save lives."

neural.disruption writes "According to the EETimes, HP is announcing that it 'plans to unveil RRAM prototype chips based on memristors with crossbar arrays in 2009.' I don't know if you remember the earlier story about HP Labs proving the existence of the Memristor that had been predicted in 1971 by Leon Chua, and has the nice property of maintaining a memory of the current that passes by it. This could bring us a new type of small non-volatile high-speed RAM at low cost because of the low complexity of the mechanism employed."

An anonymous reader writes "You probably knew that the Deep Blue supercomputer beats chess masters, and that last weekend a software robot defeated four poker champions. But you may have missed this one: a GE Fanuc robot is taking on humans at air hockey. The robot is powered by a special PC-board that can instantly switch between 8-bit and its 32-bit modes. The 8-bit version lost to most human players, but the 32-bit microcontroller has defeated even the best human air hockey players by a ratio of three to one."

An anonymous reader writes "By using the Earth's vast underground caverns to store compressed air generated by wind farms at night, several U.S. municipalities will be 'going green' by using that stored energy to generate daytime electricity on the cheap. Engineers at a National Lab think compressed air stored in underground caverns could cut in half the cost of electricity."

An anonymous reader writes "'The blind will see again,' could be the motto of the Artificial Retina Project, which is getting ready to implant a 60-pixel artificial retina chip into 10 blind patients later this year. 60-pixels doesn't sound like much, but the 1st gen artificial retina brought tears to the eyes of its six recipients, who claim they can now count large objects with just 16-pixels. If all goes well, a 200-pixel retina will be ready in three years; the chip used is of a 1.2-micron CMOS process, with both power and video supplied wirelessly." (And this is sponsored by the Department of Energy for what reason?)

chrplace forwards an article in which Gartner's Brian Lewis offers his perspective on what led to last year's Xbox 360 recall. Lewis says it happened because Microsoft wanted to avoid an ASIC vendor. "Microsoft designed the graphic chip on its own, cut a traditional ASIC vendor out of the process, and went straight to Taiwan Semiconductor Manufacturing Co. Ltd., he explained. But in the end, by going cheap — hoping to save tens of millions of dollars in ASIC design costs, Microsoft ended up paying more than $1 billion for its Xbox 360 recall. To fix the problem, Microsoft went back to an unnamed ASIC vendor based in the United States and redesigned the chip, Lewis added. (Based on a previous report, the ASIC vendor is most likely the former ATI Technologies, now part of AMD.)"

An anonymous reader writes "Water cooling will enable multi-core processors to be stacked into 3D cubes, according to IBM's Zurich Research Laboratory which is demonstrating three-dimensional chip stacks. By stacking memory chips between processor cores IBM plans to multiply interconnections by 100 times while reducing their feature size tenfold. To cool the stack at a rate of 180 watts per layer, water flows down 50-micron channels between the stacked chips. Earlier this year, the same group described a copper-plate water cooling method for IBM's Hydro-Cluster supercomputer. The Zurich team predicts high-end IBM multicore computers will migrate from the copper-plate water-cooling-method to the 3-D chip-stack in five to 10 years." Reader Lilith's Heart-shape adds a link to the BBC's article on these internally-cooled chips.

Multiple readers have written to let us know that an experiment at the upcoming Hackers on Planet Earth (HOPE) conference will use RFID to track the movements of at least 1,500 registrants for the duration of the conference. Those movements will be transmitted onto screens which "show in real-time where people go, with whom they associate, for how long and how often." The system will also be used for games which involve manipulation of the available data. Meanwhile, researchers at the Georgia Institute of Technology have developed a method for testing large quantities of RFID tags, which may serve to greatly speed distribution.

An anonymous reader writes "Raytheon is bringing 'Iron Man' to life, according to EETimes. 'The movie opens in theaters worldwide today, but the real "iron man" has already been under construction at Raytheon Company (Salt Lake City, Utah) since 2000. Raytheon's Exoskeleton project is the brainchild of project leader Stephen Jacobsen and is being funded by the U.S. Army. The project, according to the company, permits soldiers to don an Exoskeleton suit that amplifies their strength — enabling them to lift 200-pound payloads without tiring.'"

stress_life writes "Recent rumors about AMD firing 5% of its workforce proved to be understated. AMD just announced that the company is going to deliver pink slips to 1600-1700 workers, or around 10% of its employees. AMD needs revenue of $2 billion per quarter, but Q1'08 is expected to come in around $1.5 billion. These firings have to be complete by Q3'08, the quarter by which Hector Ruiz promised to be profitable." We most recently discussed AMD's struggles in February.

An anonymous reader writes "Engineers' focus and attention to details, along with their perceived lack of social skills, make them ideal targets to be recruited as terrorists, according to EETimes. Planning skills make engineers good 'field operatives' was written up by Raphael Perl, who heads the Action against Terrorism Unit of Organization for Security and Cooperation in Europe. He offers that 'Engineers ideally make excellent strategic planners, and they make excellent field operatives. They think differently from how other people think.' That may sound like a stereotype, but Perl claims that 'because of those traits, terrorist groups actively recruit engineers.' He says that Al-Qaeda has widely acknowledged that a significant number of the group's top leadership had engineering backgrounds." This is the second time in just a few months that engineers have been likened to terrorists.

kamlapati sends us to EETimes for news that the Chaos Computer Club in Germany and researchers from the University of Virginia have cracked the encryption scheme used in a common RFID chip, NXP's Mifare Classic. According to the article the device is used in many contactless smartcard applications including fare collection, loyalty cards, and access control cards. NXP downplays the significance of the hack, saying that that model of RFID card uses old technology and they do a much better job these days.

Blowfishie writes "Rambus has won a major case they've been fighting since the late 90's. Rambus worked its technology into the standards for SDRAM and DDR data transfer, then waited for the major players (Hynix, Micron and Nanya) to be heavily committed before revealing that it had patents on the technology. 'At issue is whether the developer of a speedy new memory technology deserved to be paid for its inventions, or whether the company misled memory chip makers. "I think they (the jurors) misapprehended what the standards-setting organizations are about and the absolute need for good faith," said Jared Bobrow, an outside attorney for Micron. Wednesday's verdict comes after a judgment against Hynix in 2006 that resulted in a $133 million award to Rambus, Lavelle said, and potentially clears the way for Rambus to collect on that verdict.'"

StarEmperor writes "A team of Canadian and German scientists have fabricated a room-temperature superconductor, using a highly compressed silicon-hydrogen compound. According to the article,"The researchers claim that the new material could sidestep the cooling requirement, thereby enabling superconducting wires that work at room temperature.""

kamlapati writes in with a followup from the news last month that Microsoft and Intel are funding a laboratory for research into parallel computing at UC Berkeley. The new development is the imminent delivery of the FPGA-based Berkeley Emulation Engine version 3 (BEE3) that will allow researchers to emulate systems with up to 1,000 cores in order to explore approaches to parallel programming. A Microsoft researcher called BEE3 "a Swiss Army knife of computer research tools."

An anonymous reader writes "Passing the Turing test is the holy grail of artificial intelligence (AI) and now researchers claim it may be possible using the world's fastest supercomputer (IBM's Blue Gene). This version of the Turing test pits a human conversing with a synthetic character powered by Rascals software crafted at Rensselaer Polytechnic Institute. RPI is aiming to pass AI's final exam this fall, by pairing the most powerful university-based supercomputing system in the world with its new multimedia group which is designing a holodeck, a la Star Trek."

MOBE2001 writes "There is widespread disagreement among experts on how best to design and program multicore processors, according to the EE Times. Some, like senior AMD fellow, Chuck Moore, believe that the industry should move to a new model based on a multiplicity of cores optimized for various tasks. Others disagree on the ground that heterogeneous processors would be too hard to program. The only emerging consensus seems to be that multicore computing is facing a major crisis. In a recent EE Times article titled 'Multicore puts screws to parallel-programming models', AMD's Chuck Moore is reported to have said that 'the industry is in a little bit of a panic about how to program multicore processors, especially heterogeneous ones.'"

Roland Piquepaille writes "According to EE Times, a California-based company called QuantumSphere has developed nanoparticles that could make hydrogen cheaper than gasoline. The company says its reactive catalytic nanoparticle coatings can boost the efficiency of electrolysis (the technique that generates hydrogen from water) to 85% today, exceeding the Department of Energy's goal for 2010 by 10%. The company says its process could be improved to reach an efficiency of 96% in a few years. The most interesting part of the story is that the existing gas stations would not need to be modified to distribute hydrogen. With these nanoparticle coatings, car owners could make their own hydrogen, either in their garage or even when driving."

tringtring alerts us to news that the National Science Foundation has requested $20 million in funding to work on "Science and Engineering Beyond Moore's Law." The PC World article goes on to say that the effort "would fund academic research on technologies, including carbon nanotubes, quantum computing and massively multicore computers, that could improve and replace current transistor technology." tringtring notes that quantum computing has received funding on its own lately, and work on multicore chips has intensified the hunt for parallel programming. Also, improvements are still being made to current transistor mechanics.

An anonymous reader writes "Do engineers have a way of looking at the world not all that different from terrorists? According to an article in the EE Times, they do. The story cites 'Engineers of Jihad,' a paper (pdf download) by two Oxford University sociologists, who found that graduates in science, engineering, and medicine are strongly overrepresented among Islamist movements. The paper also found that engineers are 'over-represented' among graduates who gravitate to violent groups. Authors Diego Gambetta and Steffen Hertog chalk this all up to what they call the 'engineering mindset,' which they define as 'a mindset that inclines them to take more extreme conservative and religious positions.' Is this just pop psychology masquerading as science?"

bcmbyte writes "IBM in recent months has been hit with lawsuits filed on behalf of thousands of U.S. employees who claim the company illegally classified them as exempt from federal and state overtime statutes in order to avoid paying them extra whenever they worked more than 40 hours per week. The good news for those workers is that IBM now plans to grant them so-called "non-exempt" status so they can collect overtime pay. The bad news: IBM will cut their base salaries by 15% to make up the difference."

An anonymous reader writes "It has been all over the news today: AMD announced the first of its Extensions for Software Parallelism, a series of x86 extensions to make parallel programming easier. The first are the so-called 'lightweight profiling extensions.' They would give software access to information about cache misses and retired instructions so data structures can be optimized for better performance. The specification is here (PDF). These extensions have a much wider applicability than just parallel programming — they could be used to accelerate Java, .Net, and dynamic optimizers." AMD gave no timeframe for when these proposed extensions would show up in silicon.

brownsteve writes "Eastman Kodak Co. has unveiled what it says are 'next-generation color filter patterns' designed to more than double the light sensitivity of CMOS or CCD image sensors used in camera phones or digital still cameras. The new color filter system is a departure from the widely used standard Bayer pattern — an arrangement of red, green and blue pixels — also created by Kodak. While building on the Bayer pattern, the new technology adds a 'fourth pixel, which has no pigment on top,' said Michael DeLuca, market segment manager responsible for image sensor solutions at Eastman Kodak. Such 'transparent' pixels — sensitive to all visible wavelengths — are designed to absorb light. DeLuca claimed the invention is 'the next milestone' in digital photography, likening its significance to ISO 400 color film introduced in the mid-1980's."

whoever57 writes "The DVD Copy Control Association (DVD CCA) has lost its bid to shut down Kaleidescope, which manufactures media servers that can copy DVDs (along with decryption keys) to built in hard drives. The DVD CCA claimed that this violated the terms of the contracts that control DVD-related equipment because the DVD need not be physically present for payback. However, the judge ruled against the DVD CCA on the narrow grounds that part of the specification of the Content Scrambling System was not part of the overall license agreement. This may open up the market for similar devices."

alphadogg writes "Badly designed Web sites may have negative effects on a user's immune, cardiovascular, and nervous systems, a study says. The study of 2,500 users was commissioned by Rackspace Managed Hosting and published by the UK's Social Issues Research Centre. It found that five technology flaws in Web sites may have deleterious effects." How long before the first class action suit in the U.S. over bad Web site design?

BogusToo writes to mention an EE Times article describing the interface for the OLPC project laptop. Using some fairly intuitive UI concepts (like simplified web browsers and a chat client), the Linux-based system attempts to do away with the kludgey parts of computer use. A video demo of the interface has been placed on YouTube. From the article: "Earlier postings around the Internet have also shown how the physical design of the laptop has changed, including the elimination of the much touted on-board hand crank that was supposed to power the cheap, lime green laptop. It's still there, reportedly, but has now been moved to the power adapter. The OLPC's produced earlier this week in Shanghai still need to go through loads of testing, such as knocking them off desks and dropping them in mud, as kids are wont to do. They may also be kicked around, like soccer balls, a popular sport in 99.9 percent of the world."

eldavojohn writes "For a while there, I didn't know what to buy. Blu-Ray or HD-DVD? Which would be the leader? Only a fool would buy discs of the technology that would be the next Betamax. Fortunately, my dilemma has been solved by Broadcom. From the article: 'Consumer and communications chip supplier Broadcom Corp. Thurs. (Nov. 9) introduced what the company labeled the first single-chip solution to support both Blu-ray Disc and HD-DVD standards.' I guess I'll just wait until I can get a player that will play them both."

Cr0w T. Trollbot writes "Today Transmeta filed suit against Intel for patent infringement. From the article: 'The suit [...] alleges that Intel infringed upon ten of Transmeta's patents.

hairyfeet writes, "The EETimes describes the new Samsung memory, phase-change RAM, called PRAM. Samsung is dubbing it 'Perfect RAM' because it is thirty times faster than NOR flash, ten times more durable — and cheaper to produce, to boot." 512-Mbit modules should be available sometime in 2008. None of the initial coverage goes much beyond Samsung's press release. At the same time, Samsung also announced a 40-nm, 32-Gbit NAND flash device.

AdamWeeden writes "According to the EETimes, many of the states in the U.S. have entered into a class-action lawsuit against a group of eight DRAM manufacturers. The companies are accused of price-fixing computer memory for over five years, beginning in the late 1990s." From the article: "Four companies and 12 executives have so far pleaded guilty to participating in the conspiracy and have been assessed more than $730 million in fines. In May, three of the four companies, Samsung Electronics, Hynix Semiconductor Inc. and Infineon Technologies AG agreed to pay a total of $160 million to settle class action suits related to price fixing. Elpida Memory Inc., the fourth company to plead guilty, is still involved in the class-action suits."

morpheus83 writes "Ricoh claims they have developed an optical component that reads and writes all disk formats -- Blu-ray Disc and HD-DVD, as well as DVD and CD -- with one pickup and one objective lens. The component is a 3.5-mm diameter, 1-mm thick round diffraction plate with minute concentric groves on both sides which function as a diffraction grating. Based on disc information the drive can identify which format disk is loaded, Ricoh's optical diffraction component adjusts the laser beam with its diffraction grating for each format and passes it to the objective lens."
