angry tapir writes "Intel's experimental solar-powered processor may have started off as a fun project, but the chip maker is now looking to extend the technology to hardware such as graphics processors, memory and floating point units. Intel last year showed the low-power processor — charged only by the light from a reading lamp — running Windows and Linux PCs. Intel is expected to share further details about the processor, which is code-named Claremont, at the International Solid-State Circuits Conference in San Francisco. The company is also expected to reveal information about efforts to integrate wireless capabilities into Atom chips for mobile devices."

Lucas123 writes "New research shows that far more than wireless network or CPUs, the NAND flash memory in cell phones, and in particular smartphones, affects the device's performance when it comes to loading apps, surfing the web and loading and reading documents. In tests with top-selling 16GB smartphones, NAND flash memory slowed mobile app performance from two to three times with one exception, Kingston's embedded memory card; that card slowed app performance 20X. At the bottom of the bottleneck is the fact that while network and CPUs speeds have kept pace with mobile app development, flash throughput hasn't. The researchers from Georgia Tech and NEC Corp. are working on methods to improve flash performance (PDF), including using a PRAM buffer to stage writes or be used as the final location for the SQLite databases."

Barence writes "In 2006, AMD could seemingly do no wrong. Its processors were the fastest in the PC market, annual revenue was up a record 91%, expansion into the graphics game had begun with the high-profile acquisition of ATI, and it was making exciting plans for a future where it looked like it could 'smash Intel's chip monopoly' for good. Now the company is fighting for its very survival. How did AMD end up surrendering such a advantageous position – and was it given an unfair shove on the way down? This article has plotted AMD's decline, including the botched processor launches, the anti-competitive attacks from Intel and years of boardroom unrest."

New submitter Dave_Minsky writes "The U.S. Secret Service responded to a FOIA request on Monday that reveals the names of the printer companies that cooperate with the government to identify and track potential counterfeiters. The Electronic Frontier Foundation revealed in 2005 that the U.S. Secret Service was in cahoots with selected laser printer companies to identify and track printer paper using tiny microscopic dots encoded into the paper. The tiny, yellow dots — less than a millimeter each — are printed in a pattern over each page and are only viewable with a blue light, a magnifying glass or a microscope. The pattern of dots is encodes identifiable information including printer model, and time and location where the document was printed." Easy enough to avoid government dots; just don't buy printers from Canon, Brother, Casio, HP, Konica, Minolta, Mita, Ricoh, Sharp, or Xerox.

Hints of the new display's resolution were found in iBooks 2, which contains hi-DPI versions of its artwork. The iPad 3 is rumored to be launching in early March."

First time accepted submitter core_tripper writes "Students at the University of Twente have stolen thirty laptops from various members of the university's staff. They were not prosecuted for this, so they could just get on with their studies. Indeed, these students even received ECTS credits for these thefts. UT researcher Trajce Dimkov asked the students to steal the machines as part of a scientific experiment. Stealing these laptops turned out to be a pretty simple matter."

MojoKid writes "OpenXC is an open source connectivity platform developed in tandem by Ford and open source hardware maker Bug Labs. Announced this fall, the platform is designed to allow developers the ability to use Android- and Arduino-based modules to interact with a vehicle's in-car tech, such as vehicle sensors and GPS units. The OpenXC website succinctly describes the platform as 'an API to your car.' Ford announced that OpenXC beta test kits are now shipping to developers worldwide, including U.S. institutions such as MIT and Standford as well as India's HCL Technologies."

New submitter jank1887 writes "Back in 2010, the aid organization Climate Healers gave a number of solar-powered cookstoves to rural Indian villages. The stoves were rejected by the communities, mainly because they were useless when they were wanted most: for the evening meal sometimes after the sun goes down, and for breakfast before the sun has risen. Following this, the group issued a challenge to EngineeringForChange. Details of the challenge include the need to provide 1kW of heat at about 200C for two hours in both early morning and late evening, and the users should be able to cook indoors, while sitting. A number of groups, mainly at U.S. and Indian engineering institutions, accepted the challenge, and developed potential solutions. Now, almost a year later, the ten finalist designs have been selected. The actual papers have been posted to the E4C challenge workspace. The goals of most of the designs are to keep the technology simple, although there are a few exceptions, and many include sand-, oil-, and salt-based concentrated thermal storage. Many reports include some level of discussion on the social and economic considerations, barriers to acceptance and sustainability, and how to overcome initial resistance to adoption."

cylonlover writes "This year is a historic one for nuclear power, with the first reactors winning U.S. government approval for construction since 1978. Some have seen the green lighting of two Westinghouse AP1000 reactors to be built in Georgia as the start of a revival of nuclear power in the West, but this may be a false dawn because of the problems besetting conventional reactors. It may be that when a new boom in nuclear power comes, it won't be led by giant gigawatt installations, but by batteries of small modular reactors (SMRs) with very different principles from those of previous generations. However, while it's a technology of great diversity and potential, many obstacles stand in its path. This article takes an in-depth look at the many forms of SMRs, their advantages, and the challenges they must overcome."

ananyo writes "DNA origami, a technique for making structures from DNA, has been used to build devices that can seek out and potentially destroy cancer cells. The nanorobots use a similar system to cells in the immune system to engage with receptors on the outside of cells. The barrel-shaped devices, each about 35 nanometers in diameter, contain 12 sites on the inside for attaching payload molecules and two positions on the outside for attaching aptamers, short nucleotide strands with special sequences for recognizing molecules on the target cell (abstract). The aptamers act as clasps: once both have found their target, they spring open the device to release the payload. The researchers tested six combinations of aptamer locks, each of which were designed to target different types of cancer cells in culture. Those designed to hit a leukemia cell could pick that cell out of a mixture of cell types, then release their payload — in this case, an antibody — to stop the cells from growing. The researchers designed the structure of the nanorobots using open-source software, called Cadnano."

Zothecula writes "Inspired by origami and children's pop-up books, Harvard engineers have pioneered a means of mass-producing bee-sized flying microrobots. The breakthrough mechanizes the already state-of-the art process of making Harvard's Mobee robots by hand, by mass producing flat assemblies by the sheet which can be folded and assembled in a single movement. The technique, which cunningly exploits existing machinery for making printed circuit boards, can theoretically be applied to a multitude of electromechanical machines."

An anonymous reader writes "The idea is simple — load up a microchip with a whole pharmacy of drugs that are dispensed as needed automatically. The devil has been in the details, since mistakes could kill the patient if, say, a leak developed dumping dangerous cocktails into the bloodstream. This MIT sponsored company, however, claims to have perfected wireless control of a pharmacy-on-a-chip and has just completed the clinical trials to prove it. The test microchip has just 20 doses of a single drug, but their new prototype will house thousands of pin-prick sized drug reservoirs, after which they will seek FDA approval. The elderly (who have complicated drug regime) and soldiers could both benefit from these smart pharmacies-on-a-chip, since drugs can be dispensed even if the patient is unconscious."

Lucas123 writes "A new study by the University of California and Microsoft shows that NAND flash memory experiences significant performance degradation as die sizes shrink in size. Over the next dozen years latency will double as the circuitry size shrinks from 25 nanometers today, to 6.5nm, the research showed. Speaking at the Usenix Conference on File and Storage Technologies in San Jose this week, Laura Grupp, a graduate student at the University of California, said tests of 45 different types of NAND flash chips from six vendors using 72nm to 25nm lithography techniques showed performance degraded across the board and error rates increased as die sizes shrunk. Triple-Level NAND performed the worst, followed by Multi-Level Cell NAND and Single-Level Cell. The researchers said MLC NAND-based SSDs won't be able to go beyond 4TB and TLC-based SSDs won't be able to scale past 16TB because of the performance degradation, so it appears the end of the road for SSDs will be 2024."

First time accepted submitter srs5694 writes "In light of the recent flood of stories about abysmal labor practices at Foxconn and other Chinese factories that produce most of the tech products we consume, the question arises: Who makes motherboards, plug-in cards, cell phones, and other devices WITHOUT relying on labor practices that are just one rung above slave labor? If I want to buy a new tech gadget, from whom can I buy it without ethical qualms?"

ptorrone writes "MAKE Magazine's article talks about some of the {unspoken} rules most/all the open-source hardware community seems to follow. Why? Because the core group of people who've been doing what is collectively called 'open source hardware' know each other — they're friends, they overlap and compete in some ways, but they all work towards a common goal: sharing their works to make the world a better place and to stand on each others shoulders and not each others toes : ) There will be some folks who agree strongly with what they've outlined as 'unspoken rules,' others, will completely disagree with many points too. That's great, it's time we start this conversation!"

New submitter pjlehtim writes "In a recent interview. Samsung's AV product manager, Chris Moseley, said, 'TVs are ultimately about picture quality. ... and there is no way that anyone, new or old, can come along this year or next year and beat us on picture quality.' Sounds familiar? There must be a change in the perceived role of television in the entertainment ecosystem before the general public starts to care about the smart TVs manufacturers are trying to push. That change is likely to come from outside the traditional home entertainment industry. It's not about technology; it is about user experience, again."

itwbennett writes "Sony on Tuesday demonstrated new 'smart sockets' that 'perform authentication whenever a device is plugged in,' said Taro Tadano, a general manager in Sony's technology development division. The company also demoed a home power grid that tracks electricity use by time and appliance." This has led to speculation that the technology will be used in some places to charge consumers for the use of electricity.

HerbieTMac writes "Political science professor Francis Fukuyama builds and flies his own personal surveillance drones. His current model requires ground visibility but he is working on the HAM license that would allow fully remote operation. His YouTube videos (video 1 , video 2) are particularly impressive." I had no idea that Francis Fukuyama had such technical interests.

Last Friday, an article in Eurogamer about the Raspberry Pi's upcoming release threw a wrench in the mental gears of anyone hoping to soon order one of the long-awaited (and much anticipated) boards, which had been expected to be ready for orders sometime this month. The piece was based on an interview with David Braben — since picked up, and subsequently corrected, by others as well — and it gave the impression both that a sudden delay had cropped up in the schedule (so that the boards wouldn't be available for consumers until September), and that the price might rise as well. The Raspberry Pi site says that both of these were mistaken, and clarifies (with some bold print, even): "You will be able to buy a Raspberry Pi from the end of February, from this website. The 'consumer release' that Eurogamer is talking about is actually the educational release, which, as you’ll be aware if you’ve been hanging out on our forums, will come with a kid-targetted software stack, a heap of written support materials, and a standard case." That educational version sounds like it's got enough value added to justify a higher price and a longer wait, but you can unwrench those gears if you're just interested in the plain (unboxed) board instead.
