the_newsbeagle writes "Currently, the best way to check if a person has a high likelihood of developing Alzheimer's is to perform a PET scan to measure the amount of amyloid plaque in his or her brain. That's an expensive procedure. But a startup called Akili Interactive says it has developed a mobile game that can identify likely Alzheimer's patients just by their gameplay and game results. The game is based on a neuroscience study which showed that multitasking is one of the first brain functions to take a hit in Alzheimer's patients. Therefore the game requires players to perform two tasks at the same time."

An anonymous reader writes "For about a decade, Gene Robinson has been putting cameras on remote-controlled model aircraft and using them in search-and-rescue missions. But now the Federal Aviation Administration has shut him down, saying his efforts violate a ban on flying RC aircraft for commercial purposes. Robinson doesn't charge the families of the people he's looking for, and he created a non-profit organization to demonstrate that. He also coordinates with local authorities and follows their guidelines to the letter. The FAA shut him down because they haven't designed regulations to deal with situations like this, even though they've been working on it since 2007. 'So it's difficult to argue that his flights are more dangerous than what goes on every weekend at RC modeling sites throughout the United States, which can include flights of huge models that weigh 10 times as much as Robinson's planes; aerial stunts of nitromethane-fueled model helicopters; and the low-altitude, 500-kilometer-per-hour passes in front of spectators of model jets powered by miniature turbine engines.'"

An anonymous reader writes "Last Friday may turn out to have marked the beginning of Silicon Valley's organized labor movement--startup employees met in Palo Alto 'to share war stories and to start developing what organizers called a 'Startup Employee Equity Bill of Rights'.'" That probably should include the right to work late, for little pay, and to trade less certainty now for greater hoped-for benefits down the road. If you've been a startup employee, or started one of your own, what would you put on the wishlist?

An anonymous reader writes "My colleague at IEEE Spectrum, Eliza Strickland, looked at the home transcranial direct current stimulation (tDCS) movement. People looking to boost creativity, or cure depression, are attaching electrodes to their heads using either DIT equipment or rigs from vendors like Foc.us. Advocates believe experimenting with the tech is safe, but a neuroscientist worries about removing the tech from lab safeguards..."

the_newsbeagle writes "In Japan, workers have spent nearly three years on the clean-up and decommissioning of the ruined Fukushima Daiichi nuclear power station. They only have 37 years to go. Taking apart the plant's three melted-down reactors is expected to take 40 years and cost $15 billion. The plant's owner, TEPCO, admits that its engineers don't yet know how they'll pull off this monumental task. An in-depth examination of the decommissioning process explains the challenges, such as working amid the radioactive rubble, stopping up the leaks that spill radioactive water throughout the site, and handling the blobs of melted nuclear fuel. Many of the tasks will be accomplished by newly invented robots that can go where humans fear to tread."

the_newsbeagle writes "The former editor of Wired is betting that the 21st century skies will be filled with drones, and not the military sort. His company, 3D Robotics, is building open-source UAVs for the civilian market, and expects its drones to catch on first in agriculture. As noted in an article about the company's grand ambitions: 'Farms are far from the city's madding crowds and so offer safe flying areas; also, the trend toward precision agriculture demands aerial monitoring of crops. Like traffic watching, it's a job tailor-made for a robot: dull, dirty, and dangerous.' Also, farmers apparently wouldn't need FAA approval for privately owned drones flying over their own property."

An anonymous reader writes in about a possible game changer in wireless technology that embraces interference with great results: "It's one of those elegant inventions that only surface maybe once a decade. If it works at scale, according to IEEE Spectrum, it could 'radically change the way wireless networks operate, essentially replacing today's congested cellular systems with an entirely new architecture that combines signals from multiple distributed antennas to create a tiny pocket of reception around every wireless device.' This scheme could allow each device to use the full bandwidth of spectrum available to the network, which would 'eliminate network congestion and provide faster, more reliable data connections.' And the best part? It's compatible with 4G LTE phones, which means it could be deployed today." The idea is that an array of dumb antennas are deployed and a very powerful cluster computes signals that are sent from all of them which then appear to be a single coherent signal to only a single device. There's a short paper on the Distributed In Distributed Out technique, but it is a bit light on the mathematical details.

New submitter kalman5 writes "Dennis Aabo Sørensen is the first amputee in the world to feel sensory rich information — in real-time — with a prosthetic hand wired to nerves in his upper arm. Sørensen could grasp objects intuitively and identify what he was touching while blindfolded. The surgical team 'attached electrodes from a robotic hand to a 36-year-old volunteer's median and ulnar nerves. Those nerves carry sensations that correspond with the volunteer's index finger and thumb, and with his pinky finger and the edge of his hand, respectively. The volunteer controlled the prosthetic with small muscle movements detected by sEMG, a method that dates to the 1970s and measures electrical signals through the skin—unlike the electrodes attached to his nerves, sEMG is not invasive.' The results? 'The volunteer was able to complete the requested tasks with his prosthetic thumb and index finger 67 percent of the time the first day and 93 percent of the time by the seventh day of the experiment, Micera and colleagues report. He found the pinky finger harder to control: he was only able to accomplish the requested grip 83 percent of the time by the end of the experiment.'"

cold fjord writes "IEEE Spectrum reports, "About once a year, the Linux Foundation analyzes the online repository that holds the source code of the kernel, or core, of the Linux operating system. As well as tracking the increasing complexity of the ever-evolving kernel over a series of releases from versions 3.0 to 3.10, the report also reveals who is contributing code, and the dominant role corporations now play in what began as an all-volunteer project in 1991. While volunteer contributors still represent a plurality among developers, over 80 percent of code is contributed by people who are paid for their work. ""

the_newsbeagle writes "Chinese engineers love their superlatives: Biggest dam, fastest train, etc etc. Now they've constructed the deepest underground dark matter detector beneath a mountain in Sichuan province. Such dark matter seekers have to be buried deep to shield them from cosmic rays, because that radiation would be picked up by the detector and could be confused for radiation generated by dark matter. Other dark matter detectors are similarly subterranean: LUX, in the United States, is at the bottom of an abandoned mine in South Dakota, and a European effort called XENON lies below the Gran Sasso mountain. The Chinese researchers hope their PandaX detector will finally reveal the much-hypothesized, never-seen dark matter particles known as WIMPs."

the_newsbeagle writes "When surgeons set out to repair holes in the walls of the heart's chambers or in blood vessels, they often do invasive open-heart surgery and use sutures, staples, and glue to keep a patch in place. But the sutures and staples are a rough fix, and many of the glues on the market today don't work well on wet tissue that's continually flexed by the heart's contractions and the movement of pumping blood. Today biomaterial researchers announced a new light-activated glue that could make surgery less invasive, quicker, and easier. The adhesive was inspired by slugs' and sandcastle worms' sticky secretions, which work underwater, and it can be applied with slender tools during minimally invasive surgery. A flash of UV light then sets the glue, which bends and flexes with the tissue."

TWToxicity writes "Most prescriptions would say something like 'take two pills nightly with meal' on the bottle. Now, we may be adding a new method. Baltimore-based company WellDoc is making a national push in 2014 for doctors to prescribe their app, BlueStar, after a regional launch last Fall. BlueStar helps patients with Type II Diabetes by suggesting in real-time when to test and how to regulate their blood-sugar levels by, for example, altering their medication or food intake. Prescription apps may revolutionize mobile medicine and allow for more effective treatments because the patients get real time feedback and the data collected by the app is sent to their physicians. WellDoc is currently working on apps to monitor and coach patients with other diseases. The success of this product will rely on how many doctors prescribe it."

the_newsbeagle writes "'As 2014 dawns, China has the most active and ambitious space program in the world,' says this article. While it's true that the Chinese space agency is just now reaching milestones that the U.S. and Russia reached 40 years ago (its first lunar rover landed in December), the Chinese government's strong support for space exploration means that it's catching up fast. On the agenda for the next decade: A space station to rival the ISS, a new spaceport, new heavy-lift rockets, a global satellite navigation system to rival GPS, and China's first space science satellites."

An anonymous reader writes "IEEE Spectrum reports on a rover design being developed at NASA Ames Research Center: Super Ball Bot. The premise is that the rover's brain and scientific equipment would be suspended in the center of a structure made of rigid rods and elastic cables. The rods and cables would be deformable, allowing the rover to roll over complex terrain without damage. This design would be ideal for exploring a place like Saturn's moon Titan. Its atmosphere is thick enough that a probe could drop the rover from 100km above the surface, and it would survive the fall without a parachute. 'In a scenario studied by the team (PDF), the robot could be collapsed to a very compact configuration for launch. Once it reaches the moon, it would pop open and drop to the surface, flexing and absorbing the force of impact. By shortening and lengthening the cables that connect its rigid components, the ball bot could then roll about the surface. These same cables could be used to pull back parts of the robot, so that science instruments at the center could be exposed and used.'"

savuporo writes "The two days of DARPA's humanoid robotics challenge are now over. 16 teams entered in three categories — custom built humanoid, DARPA supplied Atlas platform, and a non-humanoid form — and competed in eight different tasks. The all-Japanese SCHAFT team scored 27 out of 32 maximum points, followed by IHMC Robotics and Tartan Rescue, with 20 and 18 points. The tasks included challenges like driving a vehicle, climbing ladders and walls, using handheld tools to cut through walls, etc. All robots had a mix of autonomy and teleoperated controls to accomplish the tasks. Full details on scores can be found here. The eight teams that scored highest will get continued funding from DARPA to compete in the final challenge in 2014. Two NASA teams also entered, and the JPL-built non-humanoid RoboSimian placed 5th, whereas the JSC built and touted 'Valkyrie' came out of competition with zero points. Team SCHAFT and Boston Dynamics (building the Atlas platform) were recently acquired by Google." Reader mikejuk says the scores "[make] the performance sound better than it actually was": " Each task could take 30 minutes and most of the robots took their time and moved as slow as ice. It seems that the teams were precomputing every move and taking a lot of time rather than getting on with the task as quickly as possible. As a result there is farther to go in creating useful rescue bots than the scores might suggest."

Freshly Exhumed writes "With the onslaught of graphene experimentation, especially in computing and RF, news from IEEE Spectrum comes that researchers at Georgia Tech have computer-modeled nanoantennas made from graphene that could provide wireless network communications between nanoscopic devices. "We are exploiting the peculiar propagation of electrons in graphene to make a very small antenna that can radiate at much lower frequencies than classical metallic antennas of the same size," said Ian Akyildiz, a professor at the Georgia Institute of Technology, in a press release. "We believe that this is just the beginning of a new networking and communications paradigm based on the use of graphene.""

the_newsbeagle writes "If you can't fix it, go around it. That's the thinking behind an experimental treatment for traumatic brain injury. Using an implanted microdevice, researchers recorded the electrical signals from a sensory region of a rat's brain, skipped over a damaged brain region that typically processes sensory information, and sent the electric signals on to the premotor cortex. This cyborg mouse could then move normally. What this means is that we're getting better at speaking the brain's language — even if we don't understand it, we can mimic it."

Garabito writes "In April 2009, Australia's then prime minister, Kevin Rudd, dropped a bombshell on the press and the global technology community: His social democrat Labor administration was going to deliver broadband Internet to every single resident of Australia. It was an audacious goal, not least of all because Australia is one of the most sparsely populated countries on Earth. ... So now, after three years of planning and construction, during which workers connected some 210 000 premises (out of an anticipated 13.2 million), Australia's visionary and trailblazing initiative is at a crossroads. The new government plans to deploy fiber only to the premises of new housing developments. For the remaining homes and businesses — about 71 percent — it will bring fiber only as far as curbside cabinets, called nodes. Existing copper-wire pairs will cover the so-called last mile to individual buildings."

szotz writes "Keeping up the pace of Moore's Law is hard, but you wouldn't know it from the way chipmakers name their technology. The semiconductor industry's names for chip generations (Intel's 22nm, TSMC's 28nm, etc) have very little to do with actual physical sizes, says IEEE Spectrum. And the disconnect is only getting bigger. For the first time, the "pay us to make your chip" foundries are offering a new process (with a smaller-sounding name) that will produce chips that are no denser than their forbears. The move is not a popular one."

the_newsbeagle writes "In spinal cord injuries, the brain's commands can't reach the lower body — so in a ground-breaking experiment at the University of Louisville, researchers are providing artificial commands via electrodes implanted in the spine. The first paralyzed people to try out the tech have already been able to stand on their own, and have regained some bowel and sexual function. A video that accompanies the article also shows paralyzed rats that were able to walk again with this kind of electrical stimulation."

Zothecula writes "Explorers have mapped the surface of the iconic Matterhorn painstakingly by foot, by satellite, and now by drone, thanks to a partnership between drone maker senseFly and nonprofit Drone Adventures. Launching a small squadron of eBee minidrones off the summit and sides of the famous Alps mountaintop, the mission tested the navigational abilities of the system and created a staggering data-rich 3D model."

the_newsbeagle writes "About four million people around the world have pacemakers implanted in their bodies, and those devices all got there the same way: surgeons sliced open their patients' shoulders and inserted the pulse-generating devices in the flesh near the heart, then attached tiny wires to the heart muscle. ... A device that just received approval in the EU seems to solve those problems. This tiny pacemaker is the first that doesn't require wires to bring the electrical signal to the heart muscle, because it's implanted inside the heart itself, and is hooked onto the inner wall of one of the heart's chambers. This is possible because the cylindrical device can be inserted and attached using a steerable catheter that's snaked up through the femoral artery."

Boston Dynamics has been making eye-catching (and sort of creepy) military-oriented robots for several years, and we've noted several times the Big Dog utility robot. The newest creation is the untethered, gas-powered Wildcat; this is definitely not something I want chasing after me. (Not as fast as the previous, tethered version — yet.)

jcatcw writes "A recent study shows that a single random up-vote, randomly chosen, created a herding behavior in ratings that resulted in a 25% increase in the ratings but the negative manipulation had no effect. An intuitive explanation for this asymmetry is that we tend to go along with the positive opinions of others, but we tend to be skeptical of the negative opinions of others, and so we go in and correct what we think is an injustice. The third major result was that these effects varied by topic. So in business and society, culture, politics, we found substantial susceptibility to positive herding, whereas in general news, economics, IT, we found no such herding effects in the positive or negative direction."

toygeek writes "'Scout,' a 4-meter-long autonomous boat built by a group of young DIYers, is attempting to cross the Atlantic Ocean. It is traveling from Rhode Island, where it launched on 24 August, to Spain, where all being well it will arrive in a few months' time. Scout has now gone about 1,000 miles (1,600 kilometers) of its planned 3,700-mile (5,900 kilometer) journey. Should it complete this voyage successfully, its passage will arguably belong in the history books."

First time accepted submitter MrMagooAZ writes "An interesting article about a questionable reaction by FEMA in response to the flooding in Colorado. It seems a small firm was working free of charge with County officials to use drones to map the area and provide near-real-time maps of the flood damage. When FEMA took control of operations one of their first acts appears to have been to not only ground the drones, but threaten the operators. 'I'm from the government and I'm here to help you?'" The drone model in question has permits from the FAA to be flown around even. The drones were replaced with manned craft that, due to the terrain, where unable to fly low enough to make useful maps.

theodp writes "Forget the dire predictions of a looming shortfall of scientists, technologists, engineers, and mathematicians, advises IEEE Spectrum contributing editor Robert Charette — the STEM crisis is a myth. In investigating the simultaneous claims of both a shortage and a surplus of STEM workers, Charette was surprised by 'the apparent mismatch between earning a STEM degree and having a STEM job. Of the 7.6 million STEM workers counted by the Commerce Department, only 3.3 million possess STEM degrees. Viewed another way, about 15 million U.S. residents hold at least a bachelor's degree in a STEM discipline, but three-fourths of them — 11.4 million — work outside of STEM.' So, why would universities, government, and tech companies like Facebook, IBM, and Microsoft cry STEM-worker-shortage-wolf? 'Clearly, powerful forces must be at work to perpetuate the cycle,' Charette writes. 'One is obvious: the bottom line. Companies would rather not pay STEM professionals high salaries with lavish benefits, offer them training on the job, or guarantee them decades of stable employment. So having an oversupply of workers, whether domestically educated or imported, is to their benefit...Governments also push the STEM myth because an abundance of scientists and engineers is widely viewed as an important engine for innovation and also for national defense. And the perception of a STEM crisis benefits higher education, says Ron Hira, because as 'taxpayers subsidize more STEM education, that works in the interest of the universities' by allowing them to expand their enrollments. An oversupply of STEM workers may also have a beneficial effect on the economy, says Georgetown's Nicole Smith, one of the coauthors of the 2011 STEM study. If STEM graduates can't find traditional STEM jobs, she says, 'they will end up in other sectors of the economy and be productive.'"

First time accepted submitter Tekla Perry writes "In 'The Augmented Reality America's Cup' Stan Honey and Ken Milnes describe the positioning, communications, graphics, and augmented reality technology they developed that will be used in the upcoming America's Cup races and, they hope, will change the way sailing is televised and watched forever after. Honey and Milnes pioneered car navigation with the startup Etak, and changed the way we watch football on TV with Sportvision's yellow line."

cartechboy writes "As Nissan develops autonomous cars for its 2020 target date, the company's engineers are modeling the tech after behaviors seen in bumblebees and fish. Nissan actually tests self-navigation algorithms in seven small toy-looking robots called EPORO. The robots have 180-degree vision (modeled after bees) and monitor each others' positions, travel nose to nose and avoid collisions--just like a school of fish. Getting small robots to zip around without bumping into things might be the first step in getting cars to do the same."

the_newsbeagle writes "This DARPA-funded smartphone app is designed to monitor veterans for signs of depression and PTSD. It screens for signals of psychological distress in a number of ways; for example, the app looks for signs of social isolation (reduced number of phone calls and texts), physical isolation (the phone isn't leaving the house), and sleep disruption (the phone is used in the middle of the night). Interestingly, the company that invented the app was testing it in Boston at the time of the Boston marathon bombing, and reports that the app picked up signals of distress in the days after the attack."

the_newsbeagle writes "Most of the researchers who work on flexible electronics imagine putting their materials to use in flexible displays, like a rollable, foldable iPad that you could cram in your pocket. And I'm not saying that wouldn't be cool. But researcher Takao Someya of the University of Tokyo has a different idea: He wants his ultra-thin, ultra-flexible electronics to be used as bionic skin. Someya and other researchers have created circuits that stick to your skin, and that can stretch and bend as you move your body. These materials are still in the labs, but the scientists imagine many uses for them. For example, if a synthetic skin is studded with pressure and heat sensors, it could be used as a lifelike covering for prosthetic limbs. There are also potential biomedical applications: The e-skin could discreetly monitor an outpatient's vital signs, and send the data to a nearby computer. The article includes a short video showing Someya's material in action."

New submitter pausz42 writes "The NASA Jet Propulsion Laboratory and Stanford University are promoting RoboSimian, a simian-inspired robot able to face environments which are hostile for men. In the DARPA Robotics Challenge the selected teams have to develop an autonomous robot able to get into a car, drive it to a disaster site and perform hazardous activities. While this prototype is the only one that that doesn't have a humanoid shape (and it's quite creepy, since it does not have a head), it seems that its three fingered limbs are better fitted for some of the difficult tasks required by the DARPA challenge."

the_newsbeagle writes "Japanese researchers are trying to develop an artificial intelligence program that can pass the standardized test required of all college-bound high school students. Interestingly, the AI is showing good progress in the history portion of the exam, because it's fairly adept at looking up answers in a vast textual database. But the so-called Todai Robot is having trouble with math, 'because the questions are presented as word problems, which the Todai Robot must translate into equations that it can solve,' as well as with physics, which 'presumes that the robot understands the rules of the universe.' If the AI does succeed in mastering the general university exam, researchers will next tackle the notoriously difficult University of Tokyo entrance exam, which will require the bot to write essays."

the_newsbeagle writes "When you've got a wacky high-tech idea that will cost a lot of money, head to China. Lockheed Martin is the latest company to heed this advice. For decades, Lockheed has investigated ocean thermal energy conversion, in which the temperature difference between warm surface water and cold deep water is leveraged to produce power. Just a few years ago, the company was working with the Navy and discussing a possible OTEC pilot project in Hawaii's Pearl Harbor. That idea has since been scrapped, and Lockheed is now partnering with a Chinese resort developer to build the 10-MW pilot plant off the coast of southern China. Lockheed hasn't disclosed the cost of building this plant, but outside experts say it might cost more than $300 million."

szotz writes "You've got falling droplets of molten tin, bright lasers, and fancy evacuated optics. What's not to love about EUV light sources? The fact that we still don't have them in production lines producing chips. Light source maker ASML says it's 'more confident' that the technology's on track now, and that the machines should meet their target brightness by 2015, in time to help pattern the 10nm generation of chips — the next next generation. We'll see. Or then again maybe we won't. The light's outside the visible range."

szotz writes "Although there was once a hint from a cosmic ray experiment (on Valentine's Day, no less), no one's found any solid evidence of monopoles (unpaired north and south magnets) flying around the cosmos. But physicists did find monopole-like quasiparticles in some exotic crystals in 2009. One of the discoverers has an article this month in IEEE Spectrum that looks at how the particles were found and what's happened since. They might seem like a wacky curiosity, but the author says we shouldn't write them off — they might one day make useful new 'magnetronic' devices."

An anonymous reader writes "We keep hearing that the 'Internet of Things' is coming – that day when we'll all have not just smart phones but also smart refrigerators, smart alarm clocks, and smart roads and bridges. A new article in IEEE Spectrum magazine makes the argument that this won't happen unless engineers do some serious rethinking of how the Internet's basic routing architecture works. The author, Anthony Liotta, offers some interesting solutions based on two networks in the human body: the autonomic nervous system and the cognitive brain."

An anonymous reader writes "IEEE Spectrum has a story about a robot that uses infra red and ultrasound to image veins, picks the one with best bloodflow, and then sticks a needle in. (video included). Veebot started as an undergrad project and the creators are aiming for better performance than a human phlebotimist before going for clinical trials. Robodracula anyone?"

An anonymous reader writes "This article is an eye opening perspective on another side effect of power generation — water usage: 'More than 40 percent of fresh water used in the United States is withdrawn to cool power plants. Renewable energy generally uses far less water, but there are glaring exceptions, such as geothermal and concentrating solar.' The article also mentions that power plants have to shut down if the incoming water is too warm to cool the plant. 'Also, even though some newer plants might use far less water, they could find that there’s far less water available as water temperatures go up and water flows go down. Another study found that nearly half of 423 U.S. plants were at risk of lower power output during droughts because their intake pipes for water were less than 3 meters below the surface.'"

New submitter countach44 writes "From an article in IEEE's Spectrum magazine: 'Upon closer consideration, moving from petroleum-fueled vehicles to electric cars begins to look more and more like shifting from one brand of cigarettes to another. We wouldn't expect doctors to endorse such a thing. Should environmentally minded people really revere electric cars?' The author discusses the controversy and social issues behind electric car research and demonstrates what many of us have been thinking: are electric cars really more environmentally friendly than those based on internal combustion engines?" Reader Jah-Wren Ryel takes issue with one of the sources, and offers a criticism from Fast Company.

the_newsbeagle writes "Fast, cheap genetic sequencing machines have the potential to revolutionize science and medicine--but only if geneticists can figure out how to deal with the floods of data their machines are producing. That's where computer scientists can save the day. In this article from IEEE Spectrum, two computational biologists explain how they're borrowing big data solutions from companies like Google and Amazon to meet the challenge. An explanation of the scope of the problem, from the article: 'The roughly 2000 sequencing instruments in labs and hospitals around the world can collectively generate about 15 petabytes of compressed genetic data each year. To put this into perspective, if you were to write this data onto standard DVDs, the resulting stack would be more than 2 miles tall. And with sequencing capacity increasing at a rate of around three- to fivefold per year, next year the stack would be around 6 to 10 miles tall. At this rate, within the next five years the stack of DVDs could reach higher than the orbit of the International Space Station.'"

Esther Schindler writes "You don't think of your supermarket as the source of geeky innovation, but you may be surprised. For example, in Steven Cherry's Supermarkets Are High-Tech Hotbeds, a Techwise Conversation with Kurt Kendall, a partner and director at Kurt Salmon, where he heads the analytics practice there, we learn: 'A lot of supermarket tech is at the checkout area. Bar-code scanning was already old hat when U.S. president George Bush the elder was allegedly amazed by them in 1992, and retailers continue to experiment with the next logical step: self-checkout systems. There's a lot of technologies out there right now that are being introduced into the retail space to understand what consumers are doing in the store, and heat-mapping is one of those technologies--using cameras in the ceiling to actually track where the consumer's going. What this information tells the retailer is where a consumer is, how they're moving around the store, whether they're dwelling in certain places, like checkout or in front of specific merchandise."

Nate the greatest writes "It looks like those 4 month old rumors are true. Amazon has confirmed today that they have bought Liquavista, a Netherlands based screen tech company. There's no info yet on how much Amazon paid to Samsung, but previous rumors suggested that the asking price was under $100 million. Amazon also isn't talking about how they plan to use the electrowetting screen tech, but many are assuming that a Color Kindle is in the works."

An anonymous reader writes "Researchers from the University of California, Santa Barbara, in collaboration with colleagues at the École Polytechnique in France, have been able to prove the theory behind LED 'droop.' LED droop is the term for how LEDs emit less light when the amount of current being pushed through them goes above a certain level. 'The cost per lumen of LEDs has held the technology back as a viable replacement for incandescent bulbs for all-purpose commercial and residential lighting.' Now that we understand what causes this, we should start to see research go into technology to circumvent LED Droop. 'LEDs have enormous potential for providing long-lived high quality efficient sources of lighting for residential and commercial applications. The U.S. Department of Energy recently estimated that the widespread replacement of incandescent and fluorescent lights by LEDs in the U.S. could save electricity equal to the total output of fifty 1 GW power plants.'" A pre-print of the team's paper is available at the arXiv.

First time accepted submitter szotz writes "The National Ignition Facility has one foot in national defense and another in the future of commercial energy generation. That makes understanding the basic justification for the facility, which boasts the world's most powerful laser system, more than a little tricky. This article in IEEE Spectrum looks at NIF's recent missed deadline, what scientists think it will take for the facility to live up to its middle name, and all of the controversy and uncertainty that comes from a project that aspires to jumpstart commercial fusion energy but that also does a lot of classified work. NIF's national defense work is often glossed over in the press. This article pulls in some more detail and, in some cases, some very serious criticism. Physicist Richard Garwin, one of the designers of the hydrogen bomb, doesn't mince words. When it comes to nuclear weapons, he says in the article, '[NIF] has no relevance at all to primaries. It doesn't do a good job of mimicking secondaries...it validates the codes in regions that are not relevant to nuclear weapons.'"

While it's hard to imagine that Google has missed something fundamental here, Mann convincingly describes why Google Glass users might experience serious problems. Quoting: 'The very first wearable computer system I put together showed me real-time video on a helmet-mounted display. The camera was situated close to one eye, but it didn’t have quite the same viewpoint. The slight misalignment seemed unimportant at the time, but it produced some strange and unpleasant results. And those troubling effects persisted long after I took the gear off. That’s because my brain had adjusted to an unnatural view, so it took a while to readjust to normal vision. ... Google Glass and several similarly configured systems now in development suffer from another problem I learned about 30 years ago that arises from the basic asymmetry of their designs, in which the wearer views the display through only one eye. These systems all contain lenses that make the display appear to hover in space, farther away than it really is. That’s because the human eye can’t focus on something that’s only a couple of centimeters away, so an optical correction is needed. But what Google and other companies are doing—using fixed-focus lenses to make the display appear farther away—is not good.'"

the_newsbeagle writes "This year, a biotech company called Ion Torrent will introduce a new chip for its genome sequencing machine, which should enable researchers and doctors to scan a complete human genome for $1000 and in just a couple of hours. Compare that to the effort required to complete the first human genome: $3 billion and 13 years. Ion Torrent has nearly reached the $1000-genome milestone by virtue of a process called 'semiconductor sequencing,' and the company's founder says his chip-based sequencing machine benefits from all the efficiencies of the computer industry. At a price point of $1000, genome scans could become a routine part of medicine. And the price could keep dropping. To test out the technology, and to investigate just how useful genome scans are these days for your typical, reasonably healthy person, the IEEE Spectrum reporter got her own genome scanned and analyzed."
