Lucas123 writes "Engineers at Disney Research in Pittsburgh have developed an algorithm that creates the illusion of a 3D surface on touch screens. Using electrical impulses, the touch screen technology offers the sensation of ridges, edges, protrusions and bumps and any combination of those textures. While Disney is not alone in developing tactile response touchscreens, its researchers said the traditional approach has been to use a library of 'canned effects,' that are played back when someone touches a screen. Disney's algorithm doesn't just playback one or two responses, but it offers a set of controls that make it possible to tune tactile effects to a specific visual artifact on the fly. 'Our algorithm is concise, light and easily applicable on static images and video streams,' the researchers stated." This summer Disney unveiled AIREAL, a system designed to give tactile sensations to people using motion control devices.

An anonymous reader writes "A day after TEPCO workers mistakenly turned off cooling pumps serving the spent pool at reactor #4 at the crippled nuclear plant comes a new accident — 6 workers apparently removed the wrong pipe from a primary filtration system and were doused with highly radioactive water. They were wearing protection yet such continuing mishaps and 'small mistakes' are becoming a pattern at the facility."
ananyo writes "Fusion unleashes vast amounts of energy that might one day be used to power giant electrical grids. But the laboratory systems that seem most promising produce radiation in the form of fast-moving neutrons, and these present a health hazard that requires heavy shielding and even degrades the walls of the fusion reactor. Physicists have now produced fusion at an accelerated rate in the laboratory without generating harmful neutrons (abstract). A team led by Christine Labaune, research director of the CNRS Laboratory for the Use of Intense Lasers at the Ecole Polytechnique in Palaiseau, France, used a two-laser system to fuse protons and boron-11 nuclei. One laser created a short-lived plasma, or highly ionized gas of boron nuclei, by heating boron atoms; the other laser generated a beam of protons that smashed into the boron nuclei, releasing slow-moving helium particles but no neutrons. Previous laser experiments that generated boron fusion aimed the laser at a boron target to initiate the reaction. In the new experiment, the laser-generated proton beam produces a tenfold increase of boron fusion because protons and boron nuclei are instead collided together directly."
An anonymous reader writes "More than 90% of nuclear regulators are being sent home due to the Federal Government shutdown, as the agency announced today that it was out of funds. Without Congressional appropriations, the nuclear watchdog closes its doors for what appears to be the first time in U.S. history. CNN reports that while a skeleton crew remains to monitor the nation's 100 nuclear reactors, regulatory efforts to prevent a Fukushima-like incident in the United States have ceased."
iONiUM writes "Samsung today unveiled the Galaxy Round phone with a curved 5.7" display. It comes with a hefty $1,000 USD price tag. This is a follow-up to the 55" curved TVs it began selling in June, and is most likely an intermediate form in the development of fold-able phones. Considering the recent LG announcement of mass OLED flexible screen production, it seems we are getting close to flexible phones. One question I wonder: will Apple follow suit? So far there has been no indication they are even attempting flexible/bendable screens."
First time accepted submitter eekee writes "The targets are high, but so is the goal: releasing Verilog source code for a GPU implementation. The source will be open source, LGPL-licensed, and suitable for loading onto an FPGA. The first target is for a 2D GPU with PCI interface; perhaps not terribly interesting in itself, but the first stretch goal is much more exciting: full OpenGL and Direct3D graphics." Unlike the Open Graphics Project, this is starting from a working 2D accelerator and mostly working 3D accelerator cloning the features of the Number Nine Ticket to Ride hardware. If they get a meelion bucks they'll overhaul the chip to support something other than PCI (although you can bridge between PCI and PCIe) and implement a modern programmable rather than fixed-function chip. Also unlike OGP, they do not appear interested in producing hardware, instead focusing entirely on the core itself for use in FPGAs (anyone want to dust off the OGD1 design?)
beckman101 writes "Two years ago the Gameduino brought retro-style gaming to the Arduino. This week its successor launched on Kickstarter, still fully open-source but with a video that shows it running some contemporary-looking demos. Plus, it has a touch screen and a pretty decent 3-axis accelerometer. Farewell to the retro?"
crookedvulture writes "The first reviews of AMD's Radeon R7 and R9 graphics cards have hit the web, revealing cards based on the same GPU technology used in the existing HD 7000 series. The R9 280X is basically a tweaked variant of the Radeon HD 7970 GHz priced at $300 instead of $400, while the R9 270X is a revised version of the Radeon HD 7870 for $200. Thanks largely to lower prices, the R9 models compare favorably to rival GeForce offerings, even if there's nothing exciting going on at the chip level. There's more intrigue with the Radeon R7 260X, which shares the same GPU silicon as the HD 7790 for only $140. Turns out that graphics chip has some secret functionality that's been exposed by the R7 260X, including advanced shaders, simplified multimonitor support, and a TrueAudio DSP block dedicated to audio processing. AMD's current drivers support the shaders and multimonitor mojo in the 7790 right now, and a future update promises to unlock the DSP. The R7 260X isn't nearly as appealing as the R9 cards, though. It's slower overall than not only GeForce 650 Ti Boost cards from Nvidia, but also AMD's own Radeon HD 7850 1GB. We're still waiting on the Radeon R9 290X, which will be the first graphics card based on AMD's next-gen Hawaii GPU." More reviews available from AnandTech, Hexus, Hot Hardware, and PC Perspective.
A few weeks ago, on his way to LinuxCon, Timothy stopped by the biggest hackerspace he'd ever seen. Houston's TX/RX Labs is not just big — it's busy, and booked. Unlike some spaces we've highlighted here before (like Seattle's Metrix:CreateSpace and Brooklyn's GenSpace, TX/RX Labs has room and year-round sunshine enough to contemplate putting a multi-kilowatt solar array in the backyard. Besides an array of CNC machines, 3-D printers, and wood- and metal-working equipment, TX/RX has workbenches available for members to rent. (These are serious workspaces, made in-house of poured concrete and welded steel tubing.) There's also a classroom full of donated workstations, lounge space, a small collection of old (but working) military trucks, and a kitchen big enough for their Pancake Science Sunday breakfasts. Labs member Steve Cameron showed me around. You saw Part One of his tour last week. Today's video is Part Two.
dcblogs writes "Gartner says new technologies are decreasing jobs. In the industrial revolution — and revolutions since — there was an invigoration of jobs. For instance, assembly lines for cars led to a vast infrastructure that could support mass production giving rise to everything from car dealers to road building and utility expansion into new suburban areas. But the "digital industrial revolution" is not following the same path. "What we're seeing is a decline in the overall number of people required to do a job," said Daryl Plummer, a Gartner analyst at the research firm's Symposium ITxpo. Plummer points to a company like Kodak, which once employed 130,000, versus Instagram's 13. The analyst believes social unrest movements, similar to Occupy Wall Street, will emerge again by 2014 as the job creation problem deepens." Isn't "decline in the overall number of people required to do a job" precisely what assembly lines effect, even if some job categories as a result require fewer humans? We recently posted a contrary analysis arguing that the Luddites are wrong.
linuxwrangler writes "NSA's new Utah data-center has been suffering numerous power-surges that have caused as much as $100,000 damage per event. The root cause is 'not yet sufficiently understood' but is suspected to relate to the site's 'inability to simultaneously run computers and keep them cool.' Frustrating the analysis and repair are 'incomplete information about the design of the electrical system' and the fact that "regular quality controls in design and construction were bypassed in an effort to fast track the Utah project."" Ars Technica has a short article, too, as does ITworld.

An anonymous reader writes "NVIDIA was caught removing features from their Linux driver and days later Linux developers have caught and confirmed AMD imposing artificial limitations on their graphics cards in the DVI-to-HDMI adapters that their driver will support. Over years AMD has quietly been adding an extra EEPROM chip to their DVI-to-HDMI adapters that are bundled with Radeon HD graphics cards. Only when these identified adapters are detected via checks in their Windows and Linux Catalyst driver is HDMI audio enabled. If using a third-party DVI-to-HDMI adapter, HDMI audio support is disabled by the Catalyst driver. Open-source Linux developers have found this to be a self-imposed limitation and that the open-source AMD Linux driver will work fine with any DVI-to-HDMI adapter."
Bismillah writes "University of Bristol researchers have come up with a way to make touch screens more touchy-feely so to speak, using ultrasound waves to produce haptic feedback. You don't need to touch the screen even, as the UltraHaptics waves can be felt mid-air. Very Minority Report, but cooler." The researchers built an ultrasonic transducer grid behind an acoustically transparent display. Using acoustic modeling of a volume above the screen, they can create multiple movable control points with varying properties. A Leap Motion controller was used to detect the hand movements.
mysqlbytes writes "The BBC is reporting the National Ignition Facility (NIF), based at Livermore in California, has succeeded in breaking even — 'During an experiment in late September, the amount of energy released through the fusion reaction exceeded the amount of energy being absorbed by the fuel — the first time this had been achieved at any fusion facility in the world.'"
sciencehabit writes "A do-it-yourself neuroscience experiment that allows students to create their own 'cyborg' insects is sparking controversy amongst scienitsts and ethicists. RoboRoach #12 is a real cockroach that a company called BackyardBrains ships to school students. The students fit the insect with a tiny backpack, which contains electrodes that feed into its antennae and receive signals by remote control — via the Bluetooth signals emitted by smartphones. A simple swipe of an iPhone can turn the insect left or right. Though some scientists say the small cyborg is a good educational tool, others say it's turning kids into psychopaths." Fitting the backpack requires poking a hole in the roach's thorax and clipping its antennae to insert electrodes.
Zothecula writes "LG today announced that it is to start mass producing flexible OLED display panels for smartphones. The company says that its technology uses plastic substrates rather than glass, and claims that a protective film on the back of the display makes it 'unbreakable' as well as bendable."
Hugh Pickens DOT Com writes "Claudia Assis writes that the US will end 2013 as the world's largest producer of petroleum and natural gas, surpassing Russia and Saudi Arabia with the Energy Information Administration estimating that combined US petroleum and gas production this year will hit 50 quadrillion British thermal units, or 25 million barrels of oil equivalent a day, outproducing Russia by 5 quadrillion Btu. Most of the new oil was coming from the western states. Oil production in Texas has more than doubled since 2010. In North Dakota, it has tripled, and Oklahoma, New Mexico, Wyoming, Colorado and Utah have also shown steep rises in oil production over the same three years, according to EIA data. Tapping shale rock for oil and gas has fueled the US boom, while Russia has struggled to keep up its output. 'This is a remarkable turn of events,' says Adam Sieminski, head of the US Energy Information Administration. 'This is a new era of thinking about market conditions, and opportunities created by these conditions, that you wouldn't in a million years have dreamed about.' But even optimists in the US concede that the shale boom's longevity could hinge on commodity prices, government regulations and public support, the last of which could be problematic. A poll last month by the Pew Research Center for the People and the Press found that opposition to increased use of fracking rose to 49% from 38% in the previous six months. 'It is not a supply question anymore,' says Ken Hersh. 'It is about demand and the cost of production. Those are the two drivers."'"
Features of Google's next Nexus phone have finally been outed, along with confirmation that the phone will be built by LG, as a result of a leaked service manual draft; here are some of the details as described at TechCrunch: "The new Nexus will likely be available in 16 or 32GB variants, and will feature an LTE radio and an 8-megapixel rear camera with optical image stabilization (there’s no mention of that crazy Nikon tech, though). NFC, wireless charging, and that lovely little notification light are back, too, but don’t expect a huge boost in longevity — it’s going to pack a sealed 2,300mAh battery, up slightly from the 2100mAh cell that powered last year’s Nexus 4. That spec sheet should sound familiar to people who took notice of what happened with the Nexus 4. Just as that device was built from the foundation laid by the LG Optimus G, the Nexus 5 (or whatever it’s going to be called) seems like a mildly revamped version of LG’s G2."
Despite the number of companies shipping or promising them, smart watches aren't the easiest sell, and Ars Technica's review of Samsung's entry illustrates why. Despite all the processing power inside, the watch is "sluggish" even for the kind of at-a-glance convenience features that are touted as the reason to have a phone tethered to an (even smarter) phone, and for the most part seems to weakly imitate features already found on that phone. There are a few features called out as cool, like a media control app, but for the most part reviewer Rob Amadeo finds little compelling in the Galaxy Gear.
