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.

redletterdave writes "If you were expecting a radically different-looking tablet from the iPad 2, prepare for a minor letdown. In the same way Apple upgraded the iPhone 4 into the iPhone 4S, the exterior of the iPad 3 mirrors that of the iPad 2, despite completely renovated and upgraded innards. iLab Factory reportedly provided Sharp with the necessary parts to build the high-resolution iPad 3 display, and in a company blog post, various iPad 3 components are displayed alongside those of the iPad 2 for quick comparison. In addition to a new camera mount that will reportedly match or improve upon the 8-megapixel camera system in the iPhone 4S, the post also revealed that the iPad 3 will be approximately 1 mm thicker than its predecessor to house Apple's upgraded components, including a bigger battery, an improved camera, and a dual-LED lit system to make the 2048 x 1536 display even brighter."

An anonymous reader writes "Last weekend, during the Nuremberg Toy Fair 2012, I spotted a really cool new system for 'professional' RC models based on Embedded Linux. The WiRC allows you to control an RC car (or any other RC vehicle) with an iOS/Android device using WiFi. The core of this system is a 240 MHz ARM9 processor, with 16 MB SDRAM and 4 MB FLASH (with 2 USB ports and 802.11b/g WiFi, a microphone input and a Speaker output). It features 8+4 channels of output. A free software SDK is now in development to code your own transmitter applications."

retroworks writes "Today's Science Daily reports on 5 new UN studies of used computer and electronics management in Africa. The studies find that about 85% of surplus electronics imports are reused, not discarded. Most of the goods pictured in 'primitive e-waste' articles were domestically generated and have been in use, or reused, for years. Africa's technology lifecycle for displays is 2-3 times the productive use cycle in OECD nations. Still, EU bans the trade of used technology to Africa, Interpol has describes 'most' African computer importers as 'criminals,' and U.S. bill HR2284 would do the same. Can Africa 'leapfrog' to newer and better tech? Or are geeks and fixers the appropriate technology for 83% of the world (non-OECD's population)? "

acadiel writes "Matthew H from the AtariAge.com TI-99/4A forum has finalized a design of a TMS 9918A replacement (with VGA out) for classic computer systems such as the ColecoVision, TI-99/4A, SpectraVision, MSX1, SpectraVision 128, and Tomy Tutor Home computers. This hardware project replaces the native video controller on these classic systems and enables them to have VGA output for the first time." (It's just under $100 to order one.)
