DeviceGuru writes "Harvard University's tiny microrobotic fly, hailed by its creators as 'the first robotic fly that is able to generate enough thrust to takeoff,' will be showcased at New York's Museum of Modern Art starting Feb. 24. The life-sized 'Flybot' reportedly has a wingspan of 1.2 inches (3 cm) and weighs a mere 0.002 ounces (60 mg). This project of the Harvard University Microbotics Lab has received funding from DARPA, the U.S. Defense Advanced Research Projects Agency, which hopes to gain access to micro-miniature surveillance technologies."

An anonymous reader writes "My Health Sciences Campus has about 8,000 desktop computers, and on any given night about half of them are left on. I know this because I track all the MAC addresses in case there is a virus outbreak. Aside from the current fad of 'being green', has anyone had any success in encouraging users to power-down at night? You could potentially eliminate running bots, protect yourself from the next virus outbreak, keep your data safe, etc. Do security concerns and power consumption issues matter enough to do this?"

dulceLeche writes "While the OLPC was not designed with the American consumer in mind, people that took part in the Give One Get One program have been having fun with their XOs. The XO has a number of limitations, but with some work you can get Opera running, chat over your mesh network, and much more. An article at Geek.com explains what a few folks were able to do with their XOs."

Roland Piquepaille writes "In recent years, we've started to use our cellphones not only for placing calls or exchanging messages. Now, we take pictures, read our e-mails, listen to music or watch TV. But, according to New Scientist, UK researchers are going further with a prototype software that turns your cellphone into a 3-D mouse. The phone is connected to your computer via Bluetooth. And you control the image on the screen by rotating or moving your phone. As says one of the researchers, 'it feels like a much more natural way to interact and exchange data.' The technology might first be used in shopping malls to buy movie tickets or to interact with advertising displays."

trogador writes with the news that researchers are working to teach AIs how to play games as an exercise in reinforced learning. Software constructs have been taught to play games like chess and checkers since the 50s, but the Department of Information Systems at Eotvos University in Hungary is working to adapt that thinking to more modern titles. Besides Ms. Pac-Man, game like Tetris and Baldur's Gate assist these programs in mapping different behaviors onto their artificial test subjects. "Szita and Lorincz chose Ms. Pac-Man for their study because the game enabled them to test a variety of teaching methods. In the original Pac-Man, released in 1979, players must eat dots, avoid being eaten by four ghosts, and score big points by eating flashing ghosts. Therefore, a player's movements depend heavily on the movements of ghosts. However, the ghosts' routes are deterministic, enabling players to find patterns and predict future movements. In Ms. Pac-Man, on the other hand, the ghosts' routes are randomized, so that players can't figure out an optimal action sequence in advance."

Weather Storm writes "According to MSNBC.com, the FCC will try again to test prototypes on Jan. 24 for transmitting high-speed Internet service over unused television airwaves. The devices were developed by Microsoft and Motorola, among other corporate partners, and will be tested in laboratory and real-world conditions for three months. 'Last year, a high-technology coalition — which included Microsoft, Google Inc., Dell Inc., Hewlett-Packard Co., Intel Corp. among others — submitted prototypes they said could transmit broadband Internet service over unlicensed and unused TV spectrum, known as "white spaces." Television broadcasters and the wireless microphone industry say such devices could interfere with programming. The Initial prototype testing failed last July because the devices did not reliably detect and avoid TV programming signals and could have caused interference. If the tests are successful this time and the devices are approved, the coalition plans to introduce commercial devices for sale after the digital television transition in February 2009.'"

pizzach noted that the MacBook Air battery is actually fairly easy to replace. "All it requires is a philips screwdriver. Unlike some of Apple's other products, the battery is not so soldered in which should make a lot of people at least a little bit happier." I think I'll have to wait for something with a bigger screen and a faster clock speed.

Dotnaught writes to tell us InformationWeek is reporting that the CIA admitted today that recent power outages in multiple cities outside the United States are the result of cyberattacks. "We have information, from multiple regions outside the United States, of cyber intrusions into utilities, followed by extortion demands. We suspect, but cannot confirm, that some of these attackers had the benefit of inside knowledge. We have information that cyberattacks have been used to disrupt power equipment in several regions outside the United States. In at least one case, the disruption caused a power outage affecting multiple cities. We do not know who executed these attacks or why, but all involved intrusions through the Internet."

drcagn writes "Ars Technica reports that Apple's new 1.1.3 firmware update unbricks iPhones damaged from unlocking and updating the firmware months ago. In September, users who hacked their iPhone's firmware to unlock it found their iPhone bricked when they updated to new firmware, creating a massive upset and internet furor. Although Apple claimed this was not an intended effect of the update, it held the stance that it is not their responsibility to ensure that updates work with users' warranty-voiding hacks, and many cried foul. This update, which provides new features Jobs showed off at Macworld, while not officially unbricking the iPhone, has restored iPhones from Gizmodo and a reader of the Unofficial Apple Weblog."

An anonymous reader alerts us to a report that scientists have developed silicon nanowires which convert heat into electricity at a rate 100 times greater than that of typical silicon. The developers are hopeful that this technology will allow the harvesting of waste heat as a power source, improving the efficiency of various computer chips and appliances. Quoting IEEE Spectrum: "Research teams found that they could decrease silicon's thermal conductivity--and therefore increase the conversion efficiency--by fashioning the material into nanowires with diameters of 10 to 100 nanometers and introducing defects in the silicon that slowed the flow of phonons--the acoustic vibrations in the crystal lattice of a material that carry heat. 'Defects are important here,' says Peidong Yang, a materials scientist at Berkeley. 'They can block the phonon transport from one end to the other end, so the thermal conductivity can be drastically reduced.'"

wintersynth brings us a story about a group of enthusiasts who made a catapult out of a 2,800lb industrial robot arm. They used it to launch bowling balls, fireballs, and cans of beer toward a stationary target, and they controlled the catapult's aim with a graphical UI on a laptop. "I wanted to be able to control the rotation of the robot so we could aim the robot from the laptop, but I quickly realized that since the desert is so flat, we could do some basic ranging on the target too. I also wanted the targeting to be overlaid in 3d over a photograph of the target area. The software needed to control the robot like an MMO or RTS game. I suspect that video games, in general, have some of the most optimal control interfaces. I wanted to try a control scheme similar to the area effect spell targeting in World of Warcraft."

holy_calamity writes "A Canadian chemical engineer has a novel solution to containing liquids in space. He has been experimenting with corkscrews of ribbon-like material that keep liquids suspended in their center while in microgravity. This effect is caused by the surface tension of the liquids. The helical containers allow the fluid to be sucked out of the coil in one go. In more conventional shapes, such as coffee cups, interaction between the container and the liquid's internal pressure makes the beverage break into annoying globules you have to chase with a straw."

An anonymous reader writes "According to CNET.co.uk, certain new Dell laptops with a brushed-aluminum finish are giving users more than they bargained for. 'We know this because several CNET staff were hit with an electrical charge while using Dell's new XPS M1530 — and we're not the only ones. Dell's forums are littered with user complaints about the shocking experiences they've had with some systems. The problem only seems to occur in Dell laptops that have a brushed-aluminum finish. These include the XPS M1330 and XPS M1530. It's caused by the two-pronged connection between the mains lead and the power adapter, which isn't earthed properly because of its lack of a third pin. The laptop therefore exhibits an electrical potential (voltage) between its exposed metal parts (the brushed aluminum wrist pad) and earth ground. Since there is no earth, the human body basically acts as a wire that can conduct electric current, hence the tingling, jolting sensation.'"

contraba55 wrote with a link to an Engadget story on a sign of the postmodern times. Oscar Pistorius, a world-class sprinter, has been denied a shot at participating in the Olympics this year. He's a double-amputee, but he's not out because of his handicap; he's disqualified because he's faster than most sprinters. "The runner — who uses carbon-fiber, prosthetic feet — was reviewed by the International Association of Athletics Federations (or IAAF), a review which found the combination of man and machine to be too much for its purely human competitors. According to the IAAF report, the 'mechanical advantage of the blade in relation to the healthy ankle joint of an able bodied athlete is higher than 30-percent.' Additionally, Pistorius uses 25-percent less energy than average runners due to the artificial limbs, therefore giving him an unfair advantage on the track."

pfman writes "A University of Washington researcher has developed a contact lens including circuitry and a matrix of LEDs. Although not yet a working prototype, this may be a foundation for terminator/robocop style overlay displays in which computer graphics could be superimposed on your normal vision. 'Building the lenses was a challenge because materials that are safe for use in the body, such as the flexible organic materials used in contact lenses, are delicate. Manufacturing electrical circuits, however, involves inorganic materials, scorching temperatures and toxic chemicals. Researchers built the circuits from layers of metal only a few nanometers thick, about one thousandth the width of a human hair, and constructed light-emitting diodes one third of a millimeter across.'" Kotaku notes that this has some obvious gaming implications.

Lucas123 writes "The Serial ATA International Organization just revealed that it is well along the way to finishing a specification that would remove separate power cords to external SATA drives or optical disk drives, allowing them to draw power from the host system. The resulting new cable, being called Power Over eSATA, will be compatible with the existing eSATA connector and support the current maximum interface transfer rate of 3Gb/s. The SATA organization expects the new cables to be released later this year to drive makers."

An anonymous reader writes "According to CNET.co.uk, who randomly stumbled into a booth at CES, Toshiba has created a Microsoft Surface-type system without the unwieldy table. 'The StarBoard system is really two technologies in one. Firstly, it features Hitachi's short-throw LCD projector. This is important, because the projector sits mere inches from the interactive surface. This means you get a huge — 50-inch, in fact — bright screen, which doesn't get blocked out by your head as you lean over the table. The image it projects is incredibly high-quality too, and there was no noticeable distortion.' The video attached to the article shows the system in action." It should be noted that the implication that leaning over the table blocks a projection from above is spurious; the Surface projects an image from below. The 'overhead' setup at CES was a camera designed to show onlookers what was taking place on the table.

coondoggie writes "Yet another Star Trek-like device is making its way into the real world. VoxTec's Phraselator name sounds a bit like something the Three Stooges might have used long ago but no, this PDA-like device was developed through Defense Advanced Research Projects Agency (DARPA) for use in Afghanistan and Iraq by American soldiers for communicating with locals who spoke Farsi, Dari, Pashto and other languages. It is now being used as one tool to help keep the peace between English and non-English speakers by police departments in California, Florida, Nevada. In a nutshell the $2,500 ruggedized Phraselator runs an Intel PXA255 400mHz processor that supports a built-In noise canceling microphone, a VOCON 3200 Speech Recognizer, 1GB removable SD card, 256MB of DRAM Memory and 64MB Flash Memory. It can store up to 10,000 phrases."

geekbits writes "For all those who have at one time or another been too lazy to get up off the couch and go to the fridge and get a beer, heat up some pizza, or change the channel when the remote is missing, we may be one step closer to being able to keep our tushes parked just a little while longer. There may also be some slightly more noble implications here. According to an article in The New York Times, in an experiment at Duke University, a 12-pound, 32-inch monkey made a 200-pound, 5-foot humanoid robot walk on a treadmill using only her brain activity. She was in North Carolina, and the robot was in Japan."

Lucas123 writes "A Silicon Valley startup named Device VM has a product that circumvents the boot-up process, according to a story in MIT's Technology Review.
