It's Trivially Easy To Identify You Based On Records of Your Calls and Texts (dailydot.com)
Reader erier2003 shares an article on Daily Dot: Contrary to the claims of America's top spies, the details of your phone calls and text messages -- including when they took place and whom they involved -- are no less revealing than the actual contents of those communications. In a study published online Monday in the journal Proceedings of the National Academy of Sciences, Stanford University researchers demonstrated how they used publicly available sources -- like Google searches and the paid background-check service Intelius -- to identify "the overwhelming majority" of their 823 volunteers based only on their anonymized call and SMS metadata. The results cast doubt on claims by senior intelligence officials that telephone and Internet "metadata" -- information about communications, but not the content of those communications -- should be subjected to a lower privacy threshold because it is less sensitive. Contrary to those claims, the researchers wrote, "telephone metadata is densely interconnected, susceptible to reidentification, and enables highly sensitive inferences."IEEE has more details. -
Former Employee Accuses Wireless Charging Startup uBeam of Being a Sham (ieee.org)
uBeam, a startup which has raised over $25 million for its transmitter that can charge phones, tablets, and other devices wirelessly, is under attack. Paul Reynolds, former VP of engineering at the company has accused the company of making false promises. Reynolds, who has more than 20 years of experience working on ultrasound devices, says uBeam has overstated its technology's capabilities, and there's no way it can deliver anything close to its claim in a working prototype later this year. In fact, he went all the way to call uBeam "the next Theranos". For the uninitiated, uBeam plans to create a charging station which utilizes sound waves to beam power to devices in the same room. The company, which has a team of more than 30 engineers and physicists, has been working on the product since 2011. Some of its investors include Marc Andreessen, Marissa Mayer, and "Shark" Mark Cuban. From an IEEE report: Physicists have long questioned the practicality of uBeam's plans to deliver electricity to mobile devices using ultrasound. Mark Suster, a prominent venture capitalist and uBeam investor has defended uBeam. IEEE report adds: In his article today, Suster writes that when Reynolds was at uBeam, the engineer gave no indication that he had any problems with the company's direction -- implying that the issues raised in Reynolds' blog were essentially out of the blue. uBeam itself has yet to respond to anything Reynolds has written. "Throughout my time working with him he reassured me we could solve the technical challenges and our approach was viable," Suster writes. But Reynolds told IEEE Spectrum that is simply not the case. He says that he was rarely allowed to communicate directly with Suster, on account of Perry's (Editor's note: Meredith Perry is the Founder and CEO at uBeam) management preferences. But Reynolds said that in two meetings with Suster during the summer of 2015, he voiced concerns about what the company was telling investors and reporters it could do. -

Microsoft Buys Into DNA Data Storage (ieee.org)
the_newsbeagle writes: More than 2.5 exabytes of data is created every day, and some experts estimate that 90% of all data in the world today was created in the last two years. Clearly, storing all this data is becoming an issue. One idea is DNA data storage, in which digital files are converted into the genetic code of four nucleotides (As, Cs, Gs, and Ts). Microsoft just announced that it's testing out this idea, getting synthetic bio company Twist Bioscience to produce 10 million strands of DNA that encode some mystery file the company provided. Using DNA for long-term data storage is attractive because it's durable and efficient. For example, scientists can read the genome from a woolly mammoth hair dating from 20,000 years ago. -
Zero Zero's Camera Drone Could Be A Robot Command Center In The Future (ieee.org)
Tekla Perry writes: Zero Zero Robotics comes out of stealth today with the Hover Camera drone that uses face and body recognition to follow and photograph selected subjects. Company cofounder Meng Qiu Wang explains why he did the engineering in China (he built a team of 80 that worked two years on the project), and how this flying camera will evolve to be a navigation and control system for future home robots. According Zero Zero cofounder and CEO Meng Qiu Wang, "It has two cameras. The front viewing camera is a 13-megapixel camera that records video, but also has Simultaneous Localization and Mapping (SLAM), an algorithm that allows it to determine where it is. It also has a down-facing video camera, running an algorithm called optical flow, that looks at ground at 60 frames per second, so the Hover knows when it moves and can correct itself. These visual sensors are giving inputs and actual position and speed, meanwhile, the accelerometer and gyroscope gives relative position. All these signals are fed into the flight control algorithm, so when I throw it up in the air, it can just hover there." With a price of less than $600, it should compete well against the expensive DJI Phantom 4, which is already available on the market for $1400 and features autonomous flying and tracking features. -
Intel Confirms Major Layoff: 12,000 Worldwide, 11 Percent of Workforce (ieee.org)
Tekla Perry writes: It's all about the cloud and the Internet of Things, says Intel explaining the planned layoffs, which will affect some 12,000 employees. Intel CEO Brian Krzanich promises in an email today to employees, that the "transition" will be handled with the "utmost dignity and respect." According to IEEE Spectrum, "Intel Corp. today announced that it would cut some 12,000 jobs -- that's 11 percent of its total workforce -- by mid-2017, with the majority of those affected getting the bad news within the next two months. In a press release, the company said the 'restructuring initiative' would 'accelerate its evolution from a PC company to one that powers the cloud and the billions of smart, connected computing devices,' and that the company would be increasing its investments in 'data center, IoT memory, and connectivity businesses.'" -
Researchers Can Identify You By Your Brain Waves With 100% Accuracy (business-standard.com)
An anonymous reader writes: Scientists have developed a new system that can identify people using their brain waves or 'brainprint' with 100% accuracy, an advance that may be useful in high-security applications. Researchers at Binghamton University in U.S. recorded the brain activity of 50 people wearing an electroencephalogram (EEG) headset while they looked at a series of 500 images designed specifically to elicit unique responses from person to person -- e.g., a slice of pizza, a boat, or the word "conundrum." They found that participants' brains reacted differently to each image, enough that a computer system was able to identify each volunteer's 'brainprint' with 100% accuracy. "When you take hundreds of these images, where every person is going to feel differently about each individual one, then you can be really accurate in identifying which person it was who looked at them just by their brain activity," said Assistant Professor Sarah Laszlo. One thing the paper doesn't talk about is the effect of time on the accuracy of the system. People may perceive different things when looking at the same picture a year later, for instance. -
New Full Duplex Radio Chip Transmits and Receives Wireless Signals At Once (ieee.org)
Wave723 writes: A new chip by Columbia University researchers uses a circulator made of silicon transistors to reroute signals and avoid interference from a transmitter and receiver that share the same antenna. This technology instantly doubles data capacity and could eventually be built into smartphones and tablets. The chip enables them to work around the principle of Lorentz Reciprocity, in which electromagnetic waves are thought to always travel along the same path both forward and backward. Traditionally, electronic devices required two antennas -- a transmitter and receiver -- that took turns or operated on different frequencies in order to exchange signals. -
'Neural Bypass' Links Brain To Hand To Get Around Paralysis (ieee.org)
An anonymous reader writes: People who are paralyzed from a spinal cord injury still generate movement commands in their brains, but those commands can't travel down their spinal cords and peripheral nerves to reach their muscles. So biomedical engineers came up with a "neural bypass" to route brain signals around the roadblock. The system has just been demonstrated by a human patient for the first time. The patient has a brain implant to record signals from his motor cortex which are sent to a computer, where a decoder algorithm figures out which signals correspond to which specific imagined movements. It then sends a command to a sleeve of electrodes the patient wears on his forearm, which stimulates his muscles in precise patterns to produce the desired hand movement. The patient has already poured from a bottle, stirred with a swizzle stick, swiped a credit card, and played Guitar Hero. -
New Bipedal Robot Demoed by Google X Company (i-programmer.info)
SCHAFT, one of eight robotic companies in the Alphabet/Google X research facility, has unveiled a new armless bipedal robot which can climb stairs and carry up to 132 pounds, reports i-programmer.info. The one-meter tall robot "is essentially a pair of almost entirely straight legs which pivot from the top," and the robot can walk on snow or uneven surfaces, even staying upright while researchers tried to trip it. The as-yet-unnamed robot was introduced during a keynote address at the New Economic Summit in Tokyo given by Android Inc. co-founder Andy Rubin (who left Google 18 months ago). A SCHAFT spokesperson later added that the presentation wasn't a product announcement. "The team was simply delighted to have a chance to show their latest progress." -
People Feel Weird About Touching Robot Butts, Researchers Find (techcrunch.com)
An anonymous reader quotes a report from TechCrunch: How would you feel if a robot asked you to touch its butt? Maybe it sounds like a silly question, but as robots proliferate and anthropomorphize, it's actually something that needs to be considered. So scientists at Stanford considered it. The study, to be presented soon but previewed by IEEE Spectrum, is entitled "Touching a Mechanical Body: Tactile Contact With Intimate Parts of a Human-Shaped Robot is Physiologically Arousing" -- and really, the title says it all. The researchers sat volunteers at a table with a Nao humanoid robot reclining casually on it. They were told (by the robot, in fact) that it was a vocabulary exercise focusing on terms for body parts. Volunteers were told by the bot to, for instance, "touch my ear" using their dominant hand, while the non-dominant hand remained on a skin conductance sensor that loosely monitored their physical state. When asked to touch "high accessibility" areas -- places we normally touch on other people, like shoulders and elbows -- volunteers did so without hesitation or agitation. But "low accessibility" areas -- this would be the robot's butt and where its junk would be -- produced delay and that arousal we talked about. -
Torvalds' Secret Sauce For Linux: Willing To Be Wrong (ieee.org)
An anonymous reader writes: Linux turns 25 this year(!!). To mark the event, IEEE Spectrum has a piece on the history of Linux and why it succeeded where others failed. In an accompanying question and answer with Linus Torvalds, Torvalds explains the combination of youthful chutzpah, openness to other's ideas, and a willingness to unwind technical decisions that he thinks were critical to the OS's development: "I credit the fact that I didn't know what the hell I was setting myself up for for a lot of the success of Linux. [...] The thing about bad technical decisions is that you can always undo them. [...] I'd rather make a decision that turns out to be wrong later than waffle about possible alternatives for too long." -

How To Solve VR Simulation Sickness: Strap People Into Rollercoasters
An anonymous reader writes: Theme park owners are trying to breathe new life into old rides by adding VR headsets, according to IEEE Spectrum. In the latest such ride from the UK's Alton Towers, sensors in the seats allow the virtual action to be synched with the rollercoaster's movements on a per-headset basis. As a side effect, this also eliminates the simulation sickness some VR users suffer from when making rapid movements through a virtual space, because the user's body is actually experiencing those movements. Is this cheating or the future of action VR? Counterexample: I haven't (yet!) gotten sick from VR, and generally love roller coasters, but had trouble keeping down my lunch (and then felt bad for for hours) after a vigorous flight simulator at the -- highly recommended! -- Strategic Air & Space Museum, near Omaha, Nebraska. -
Brain Implant Can Automatically Adjust Dopamine Levels (ieee.org)
Reader Wave723 writes about an implantable chip that is able to detect and adjust dopamine levels in mice brains. Created by researchers at Case Western Reserve University, the chip, unlike other brain implants, traces the neurotransmitter instead of relying on electrical signals. Wave723 elaborates: This brain implant is a chip that can automatically sense dopamine levels through an electrode that measures the flow of the neurotransmitter through the brain and pH levels. An algorithm within the device calculates whether dopamine levels are within a predetermined range, and if not, the chip sends an electrical impulse to stimulate neurons to produce more. Someday, it might help patients with a variety of disorders including addiction, or Parkinson's disease though a lot more research is needed to be done on neurotransmitter levels in order to reach that point. -
What's Frying the Electrical Systems On BART Trains? (ieee.org)
Tekla Perry writes: Earlier this month, BART engineers shut down a substation in hopes that the closure would quiet the power surges that were frying the electrical propulsion equipment on BART cars -- a peak of 40 in just one day in February. The shutdown seemed to solve the problem, but BART officials weren't sure they'd really found the answer. Yesterday, the power surges popped up again, on an entirely different section of tracks, damaging 50 cars before BART closed off that section, rerouting passengers onto buses. Track inspections yesterday revealed nothing, and BART reports that it has reached out to experts around the country and asked them to fly in and help solve the mystery. Do you have a theory? Note: BART is the 5th-busiest heavy-rail rapid transit system in the U.S. -
5 Major Hospital Hacks: Horror Stories From the Cybersecurity Frontlines (ieee.org)
the_newsbeagle writes: We don't often get insider accounts of hacks against major institutions like hospitals because they immediately go into damage control mode. But at a SXSW talk, a couple of experts told tales out of school. The experts, [John Halamka, CIO of the Boston hospital Beth Israel Deaconness, and Kevin Fu, a University of Michigan engineering professor, recounted incidents in which hackers downloaded patient X-rays to China, took down entire networks, fooled Harvard doctors, and more. -
Meet the Guy Whose Software Keeps the World's Digital Clocks In Sync (ieee.org)
New submitter Wave723 quotes a story on IEEE: In many cases, the internal clock that ticks away in a laptop or desktop computer is synchronized to an official time service maintained by the U.S. National Institute of Standards and Technology (NIST). This free service shares Coordinated Universal Time with personal devices, web browsers, financial trading software and e-mail programs throughout the world. The service receives 150,000 requests per second (roughly 16 billion a day) from systems that repeatedly ask, 'What time is it?' "If you have a PC, it's probably synchronized to the time service," says Judah Levine, the man who originally built servers and programmed software to send time over the Internet for NIST back in 1993. -
6 Tiny Robotic Ants, Weighing 3.5 Oz. In Total, Pull a 3900-lb. Car (nytimes.com)
Reader schwit1 writes about MicroTug, a team of six microrobots that weigh just 3.5 ounces (99 grams), and can move a car: Researchers at Standford University's Biomimetics and Dexterous Manipulation Lab have developed six miniature robots that have the pulling-power to move objects 2,000 times of their own body weight. The tiny robots and their inter-coordination are based on that of ants. The microrobot uses a special kind of glue on its feet that make them serve as sticky gecko toes. "Their new demonstration is the functional equivalent of a team of six humans moving a weight equivalent to that of an Eiffel Tower and three Statues of Liberty," said David Christensen, a graduate student who is one of the authors of "Let's All Pull Together: Principles for Sharing Large Loads in Microrobot Teams paper. Researchers' fascination with gecko adhesive is nothing new. In 2010, Stanford mechanical engineer Mark Cutkosky developed a Stickybot that could climb walls. A similar robot that could roll up on smooth as well rough surfaces was demonstrated by a group of researchers in Canada in 2011. -
DARPA Wants Ideas On Weaponizing Off-the-Shelf Tech (ieee.org)
An anonymous reader writes: The good news is that some of today's most advanced technologies are cheap and easy to find, both online and on the shelves of major chain stores. That's also the bad news, according to DARPA. The defense agency is nervous that criminals and terrorists will turn off-the-shelf products into tools and devices to harm citizens or disrupt American military operations. On Friday, DARPA announced a new project called 'Improv' that invites technologists to propose designs for military applications or weaponry built exclusively from commercial software, open source code, and readily available materials. The program's goal is to demonstrate how easy it is to transform everyday technology into a system or device that threatens national security. See also this story about transforming into weapons items commonly found in the purportedly secure area of U.S. airports. -
Fukushima Cleanup, 5 Years On (bbc.co.uk)
AmiMoJo writes: Today is five years since the Fukushima Daiichi nuclear plant was damaged by an earthquake and tsunami, leading to a series of meltdowns. Nearly half a million people were evacuated at the time, with 100,000 still unable to return to their homes. The government has set a goal of 20mSv/year before people are allowed to live in affected areas again, and while progress is being made hotspots are still a problem in many areas. Reconstruction has been largely waiting for decontamination to be completed, allowing homes and businesses to fall into ruin. Those who do wish to return find their communities gutted, with essential services and jobs gone. Meanwhile, engineers are still unable to determine exactly what happened at Daiichi, particularly what saved reactor 2's pressure vessel from exploding. The initial reports were scary even before the nuclear plant problems were evident. Engadget notes that even now, the worst part of the cleanup remains a grueling work in progress, tough even for robots. Reader the_newsbeagle writes, too, with a link to the New York Times' take on the 5-year mark, and notes that The state and location of the melted fuel inside the reactors is still a mystery. The meltdown zone is too dangerous for human workers to enter, and robots have had limited success navigating in the wreckage. So Japan is recruiting subatomic particles called muons to map the reactors' insides. These particles, born of cosmic rays, constantly stream down from the atmosphere, passing through most matter unimpeded. But their occasional interactions with the subatomic components of uranium allow physicists to locate the blobs of the deadly stuff. -
Reports Coming In Of Mass IBM Layoffs Underway In The US (ieee.org)
Tekla Perry writes: Last week, IBM reported to investors that its workforce at the end of 2015 was almost as big as its workforce at the end of 2014 (within less than 1 percent), in spite of a year in which 70,000 employees left the company, to be replaced with new hires and acquisitions. Today reports are coming in that massive layoffs across the United States are underway, likely one-third of the U.S. workforce, according to one soon-to-be-laid-off-IBMer. In addition, a recent change in IBM's severance policy may leave workers with less cash than anticipated. IBM maintains that things are just business as usual, but this appears to be the day IBM Watchers have long warned about. -
Tackling The Future Of Digital Trust -- While It Still Exists (ieee.org)
Tekla Perry writes: Last week at Berkeley's Center for Long-Term Cybersecurity, cybersecurity mavens from the industry, academia, government, and media considered a futuristic scenario in which traditional forms of identification and databases that use them -- drivers licenses, voting records, social security numbers, medical records, and bank accounts -- had been compromised. The challenge was to use the scenario to figure out how to establish a new means of verifying one's identity and to rebuild trust in the electronic records system in the case of such an imaginary crisis. Furthermore, they were then challenged to take the conclusions and develop policies that could prevent such a massive breach of digital trust from ever happening in the first place. -
Big Test Coming Up For Kilogram Redefinition (ieee.org)
szotz writes: Electromechanical balances have got to be better than an aged lump of platinum and iridium right? Teams are working to get kilograms measured and shipped to Paris in time for a test to see whether the technology (along with another that uses ultrapure silicon spheres) is now ready to redefine the kilogram. Why is this redefinition interesting? Because it's about using physics to overcome one problem with weight standards based on tightly held exemplars in standards bodies' inner sanctums: the mass of those exemplars can change, however subtly, introducing uncertainty and confusion. From the article: The world's metrologists aim to change this state of affairs in 2018 by fixing the kilogram to the Planck constant, a fundamental physical constant. That shift would, at least in principle, allow any laboratory to "realize" the kilogram from scratch with a series of experiments and specialized equipment. But for that scheme to work, the kilogram derived by one laboratory must be the same as those derived by others. -
Supercapacitor-On-a-Chip Now One Step Closer (ieee.org)
schwit1 writes: In 2010 Spectrum reported a new approach for creating chip-scale supercapacitors on silicon wafers, proposed by researchers at Drexel University in Philadelphia and the Universite Paul Sabatier in Toulouse, France. In an article published in Science, the researchers described how to make supercapacitor electrodes from porous carbon that could stick to the surface of silicon wafers so that they could be micromachined into electrodes for on-chip supercapacitors. Now the same team has finally succeeded in doing just that. In a paper published in this week's Science, researchers from the two initial teams report creating efficient porous carbon electrodes that really stick to the surface of a silicon wafer. They made layers of porous carbide derived carbon (CDC) that are completely compatible with all treatments used in the semiconductor industry, says Patrice Simon, a researcher at Universite Paul Sabatier who has researched porous CDC electrodes over the last ten years and co-authored both the 2010 and this week's paper in Science. -
To Respond To a Disease Outbreak, Bring In the Portable Genome Sequencers (ieee.org)
the_newsbeagle writes: Epidemiologists working on Zika virus could benefit from portable genome sequencers, like these used during the Ebola outbreak. In spring 2015, researchers conducted the first experiment in real-time genetic surveillance during an infectious disease epidemic. The researchers packed all their equipment in a couple of suitcases and set up a mobile lab in Guinea, where they used palm-sized sequencing devices to analyze viral RNA from 142 patients. Genomic data can illuminate the chains of transmission in an outbreak, and can help scientists develop diagnostics and vaccines. -
Sensors Slip Into the Brain, Then Dissolve When Their Job Is Done (ieee.org)
An anonymous reader writes: Silicon-based electronic circuits that operate flawlessly in the body for some number of days--soon weeks--and then harmlessly dissolve: they're what University of Illinois professor John Rogers says is the next frontier of electronics. Today he released news of successful animal tests on such transient electronics designed for use in brain implants, but says they could be used just about anywhere in the body. As these devices move into larger animal and eventually human tests, Rogers says he'll be working on the next generation--devices that intervene to accelerate healing or manage medical conditions, not just monitor them. -
Graphene Flakes Facilitate Neuromorphic Chips (ieee.org)
An anonymous reader writes: One of the hot areas of semiconductor research right now is the creation of so-called neuromorphic chips — processors whose transistors are networked in such a way to imitate how neurons interact. "One way of building such transistors is to construct them of lasers that rely on an encoding approach called "spiking." Depending on the input, the laser will either provide a brief spike in its output of photons or not respond at all. Instead of using the on or off state of the transistor to represent the 1s and 0s of digital data, these neural transistors rely on the time intervals between spikes." Now, research published in Nature Scientific Reports has shown how to stabilize these laser spikes, so that they're responsive at picosecond intervals. "The team achieved this by placing a tiny piece of graphene inside a semiconductor laser. The graphene acts as a 'saturable absorber,' soaking up photons and then emitting them in a quick burst. Graphene, it turns out, makes a good saturable absorber because it can take up and release a lot of photons extremely fast, and it works at any wavelength; so lasers emitting different colors could be used simultaneously, without interfering with each other—speeding processing." -
BBC Confirms 50% Bitrate Savings For H.265/HEVC Vs H.264/AVC (bbc.co.uk)
An anonymous reader writes: A research team from the BBC has done a series of tests to confirm earlier computations showing a ~50% savings in bit rate for H.265/HEVC compared to video using H.264/AVC at comparable quality. "The subjective tests used a carefully selected set of coded video sequences at four different picture sizes: UHD (3840x2160 and 4096x2048), 1080p (1920x1080), 720p (1280x720) and 480p (832x480), at frame rates of 30Hz, 50Hz, or 60Hz. The video content was chosen to represent diverse spatial and temporal characteristics, and then coded using HEVC and AVC standards at a wide span of bit rates producing a variety of quality levels." Here is the full published analysis. "The tests confirmed the significant compression efficiency improvements achieved in HEVC, verifying the results previously reported using objective quality metrics (PSNR based methods)." The team did not test against VP9, which is shaping up to be an impressive standard as well. -
DNA Manufacturing Enters the Age of Mass Production (ieee.org)
the_newsbeagle writes: Now that it's easy and cheap to build strands of DNA, what kinds of strange new organisms will scientists and start-ups build? That's the question raised as synthetic biology companies like Twist Bioscience and Zymergen start up their DNA manufacturing lines. Researchers who order DNA snippets typically pay on a cost-per-nucleobase basis. These companies say their mass-production techniques could bring prices down to 2 cents per base, which would allow researchers to scale up experiments and learn through trial and error. -
How Long Until the Cyborg Olympics Are Better Than the Traditional Games? (ieee.org)

During this event, more officially called the Cybathlon, people with disabilities will use advanced technologies such as exoskeletons and powered prosthetic limbs to compete in the games. This article chronicles one team's training for the bicycle race, where the athletes will be people with paralyzed legs. The team is composed of the paralyzed biker who has an electrical stimulation system implanted in his body, and the engineers who built the gear that energizes his nerves and muscles. -
No More QA: Yahoo's Tech Leaders Say Engineers Are Better Off Coding With No Net (ieee.org)
Tekla Perry writes: A year ago Yahoo eliminated its test and quality assurance team, as part of project Warp Drive, its move to continuous delivery of code. The shift wasn't easy, Yahoo tech execs say, and required some "tough parenting." But the result has been fewer errors because "when you have humans everywhere, checking this, checking that, they add so much human error into the chain that, when you take them out, even if you fail sometimes, overall you are doing better." And the pain wasn't as great as expected. Yahoo's chief architect and SVP of science and technology discuss the transition. -
The Quest For the Ultimate Vacuum Tube (ieee.org)
An anonymous reader writes: IEEE Spectrum reports on progress in the development of vacuum tube technology, which remains surprisingly relevant in 2015. "In the six decades since vacuum tubes lost out to solid-state devices in computers, receivers, and power supplies, vacuum technology has continued to evolve and branch out into new terrain, sustaining a small but skilled corps of engineers and scientists around the world, as well as a multibillion-dollar industry. That's because the traveling-wave tube and other vacuum devices continue to serve one purpose extremely well: as powerful sources of microwave, millimeter-wave, and submillimeter-wave radiation. And now, ongoing research into a new and potentially revolutionary kind of traveling-wave tube—the ultracompact and ultraefficient cold-cathode TWT—looks poised to deliver the first practical device by the end of this decade." -
British Spaceplane Skylon Could Revolutionize Space Travel (ieee.org)
MarkWhittington writes: The problem of lowering the cost of sending people and cargo into low Earth orbit has vexed engineers since the dawn of the space age. Currently, the only way to go into space is on top of multistage rockets which toss off pieces of themselves as they ascend higher into the heavens. The Conversation touted a British project, called Skylon, which many believe will help to address the problem of costly space travel. According to IEEE Spectrum, both BAE Systems and the British government have infused Skylon with $120 million in investment. -
Jack McCauley's Next Challenge: the Perfect Head-Tracker For VR (ieee.org)
Tekla Perry writes: He used a webcam and LEDs to do position tracking for the Oculus DK2, but Jack McCauley, co-founder of Oculus and now working independently, says that's the wrong approach. He likes the laser scanning system of the HTC Vive better, but says it's just not fast enough. McCauley thinks he can do better, using a design approach borrowed from picoprojectors. Speaking at this week's MEMS Executive Congress, he said better tracking of head position will solve the problem of VR sickness, not more expensive screen technologies. -
Lessons From a Decade of IT Failures (ieee.org)
New submitter mixed_signal writes: IEEE Spectrum has an online set of articles, or "lessons," on why big IT projects have failed, including analysis of the impacts of failed systems and the life cycles of failed projects. From the summary: "To commemorate the last decade's worth of failures, we organized and analyzed the data we've collected. We cannot claim—nor can anyone, really—to have a definitive, comprehensive database of debacles. Instead, from the incidents we have chronicled, we handpicked the most interesting and illustrative examples of big IT systems and projects gone awry and created the five interactives featured here. Each reveals different emerging patterns and lessons. Dive in to see what we've found. One big takeaway: While it's impossible to say whether IT failures are more frequent now than in the past, it does seem that the aggregate consequences are worse." -
Leap Second May Be On the Chopping Block (ieee.org)
szotz writes: The days of 61-second minutes may be coming to an end. The World Radiocommunication Conference is meeting for nearly the entire month of November, and one of the hot-button issues is what to do about the leap second. The addition to UTC is supposed to keep atomic time aligned with Earth's rotation, but past leap seconds have caused server crashes, and some are worried that future problems could be even worse. Going into the conference, it doesn't look like there's much of a consensus on what to do. One official is expecting weeks of debate. -
First New US Nuclear Reactor In Two Decades Gets Permission To Begin Fueling (ieee.org)
An anonymous reader writes: The Tennessee Valley Authority's Watts Bar nuclear power plant began construction in 1973. The plant's first reactor was completed in 1996, and it began operation. Work on the second reactor paused in 1988, and only resumed in 2007. That reactor is now complete — the first newly-operational Generation II reactor since the 1990s. The new reactor has been granted an operational license, and it will soon begin fueling. While the Gen II reactors aren't unsafe, they're much less safe than the Gen III AP1000s. "Compared to a Westinghouse Gen II PWR, the AP1000 contains 50 percent fewer safety-related valves, 35 percent fewer pumps, 80 percent less safety-related piping, 85 percent less control cabling, and 45 percent less seismic building volume. ... If an accident happens, the AP1000 will shut itself down without needing any human intervention (or even electrical power) within the first 72 hours." -
A Tower of Molten Salt Will Deliver Solar Power After Sunset (ieee.org)
schwit1 sends this report from IEEE Spectrum: Solar power projects intended to turn solar heat into steam to generate electricity have struggled to compete amid tumbling prices for solar energy from solid-state photovoltaic (PV) panels. But the first commercial-scale implementation of an innovative solar thermal design could turn the tide. Engineered from the ground up to store some of its solar energy, the 110-megawatt plant is nearing completion in the Crescent Dunes near Tonopah, Nev. It aims to simultaneously produce the cheapest solar thermal power and to dispatch that power for up to 10 hours after the setting sun has idled photovoltaics. ... [The system] heats a molten mixture of nitrate salts that can be stored in insulated tanks and withdrawn on demand to run the plant’s steam generators and turbine when electricity is most valuable. ... Eliminating the heat exchange between oil and salts trims energy storage losses from about 7 percent to just 2 percent. The tower also heats its molten salt to 566 degrees C, whereas oil-based plants top out at 400 degrees C. -
Dutch Researchers Show Connected Cars Can Be Cheaply Tracked (ieee.org)
schwit1 writes to point out an experiment undertaken on the campus of the Netherlands' University of Twente, in which two wireless sensing stations were able to cheaply pinpoint a target vehicle equipped with "smart" V2X systems nearly half the time, and track it (albeit less precisely) even more, according to Jonathan Petit, Principal Scientist at software security company Security Innovation. "You can build a real-time tracking system using off-the-shelf devices with minimum sophistication," says Petit. In a paper to be presented at the Black Hat Europe security conference in November, he describes being able to place a security vehicle within either the residential or the business zones of the campus with 78 percent accuracy, and even locate it on individual roads 40 percent of the time. The tracking here was accomplished by listening for transmissions emitted over using 802.11p at 5.9 GHz. Says the article: Petit is now working with Ford, GM, and other carmakers to develop strategies to help secure connected cars. One interesting finding from his experiment was that a Manhattan-style grid of roads makes it difficult for potential attackers because there are more connections between the intersections. "This raises the idea of privacy-enhancing road networks, where cities are designed with the concept of privacy at their core," he says. -

In 26 Hours, Sick Newborns Go From Genome Scan To Diagnosis (ieee.org)
the_newsbeagle writes: Parsing the first human genome took a decade, but times have changed. Now, within 26 hours, doctors can scan a sick baby's entire genome and analyze the resulting list of mutations to produce a diagnosis. Since genetic diseases are the top cause of death for infants (abstract), rapidly diagnosing a rare genetic disease can be life-saving. The 26-hour pipeline results from automated technologies that handle everything from the genome sequencing to the diagnosis, says the doctor involved: "We want to take humans out of the equation, because we're the bottleneck." -
Scientists Control a Fly's Heartbeat With a Laser (ieee.org)
the_newsbeagle writes: Researchers have demonstrated a laser-based pacemaker in fruit flies, and say that a human version is "not impossible."
The invention makes use of optogenetics, a technique in which the DNA that codes for a light-sensitive protein is inserted into certain cells, enabling those cells to be activated by pulses of light. Researchers often use this method to study neurons in the brain, but in this case the researchers altered flies' heart cells. Then they activated those cardiac cells using pulses of light, causing them to contract in time with the pulses (abstract). Voila, they had an optical pacemaker that worked on living adult fruit flies.
Don't worry, no one can control your heartbeat with a laser just yet. That would require inserting foreign DNA into your heart cells, and also finding a way to shine light through the impediment of your flesh and bones. But lead researcher Chao Zhou of Lehigh University is working on it. -
DARPA Jolts the Nervous System With Electricity, Lasers, Sound Waves, and Magnets
the_newsbeagle writes: DARPA is sinking some cash into the buzzy new research field of "electroceuticals," which involves stimulating nerves to control the activity of organs or bodily systems. The newest techniques have little in common with electroshock therapy, which sends a strong current broadly through the brain tissue; today's cutting-edge methods can target individual neurons, and turn them "on" and "off" with great precision. Under DARPA's new ElectRx program, seven research teams will explore different ways to modulate activity of the peripheral nervous system. Some will stimulate neurons directly with electricity, while others will take more roundabout routes involving light, acoustics, and magnetic fields. -
Advance In Super/Ultra Capacitor Tech: High Voltage and High Capacity
fyngyrz writes: Ultracaps offer significantly faster charge and discharge rates as well as considerably longer life than batteries. Where they have uniformly fallen short is in the amount of energy they can store as compared to a battery, and also the engineering backflips required to get higher voltages (which is the key to higher energy storage because the energy stored in a cap scales with the square of the cap's voltage, whereas doubling the cap's actual capacitance only doubles the energy, or in other words, the energy increase is linear.) This new development addresses these shortcomings all at once: considerably higher voltage, smaller size, higher capacitance, and to top it off, utilizes less corrosive internals. The best news of all: This new technology looks to be easy, even trivial, to manufacture, and uses inexpensive materials — and that is something neither batteries or previous types of ultracaps have been able to claim. After the debacle of EEStor's claims and failure to meet them for so long, and the somewhat related very slow advance of other ultracap technology, it's difficult not to be cynical. But if you read TFA (yes, I know, but perhaps you'll do it anyway) you may decide some optimism might actually be called for. -
ALS Patients Use a Brain Implant To Type 6 Words Per Minute
the_newsbeagle writes: With electrodes implanted in their neural tissue and a new brain-computer interface, two paralyzed people with ALS used their thoughts to control a computer cursor with unprecedented accuracy and speed. They showed off their skills by using a predictive text-entering program to type sentences, achieving a rate of 6 words per minute. While paralyzed people can type faster using other assistive technologies that are already on the market, like eye-gaze trackers and air-puff controllers, a brain implant could be the only option for paralyzed people who can't reliably control their eyes or mouth muscles. -
Hajj Pilgrimage Safety Challenges Crowd Simulator Technology
agent elevator writes: In 2010, Saudi Arabia hosted an international design competition aimed at safely accommodating more pilgrims at Mecca's Grand Mosque. One of the participants told IEEE Spectrum that the crowd densities there (6 people per square meter) bogged down off-the-shelf software so badly that simulation run times were about 10 to 20 times slower than real time crowd movement. Nevertheless, he found some workarounds that gave designers a plan to double the Grand Mosque's peak visitor rate from 40,000 to 102,000 people per hour. Last week's stampede took place well away from the mosque, but signals sent to pilgrims telling them when to speed up or slow down could help prevent such a tragedy, the crowd simulation expert said. Other engineers are turning to fuzzy logic as way to predict how crowds will react in a panic. -

Brain-Controlled (Inflatable) Shark Attack
the_newsbeagle writes: This is a parlor trick, not neuroscience," writes this DIY brain hacker — but it sure is a nifty trick. The hacker put electrodes on his scalp, fed the resulting EEG data into a specialized processor that makes sense of brain signals, and modified the remote control for a helium-filled shark balloon. Soon, he and his buddies were steering the shark around the room. Why did it take his buddies, too? "EEG interpretation is not easy because, to be technical, EEG signals are a crazy mess. EEG recordings are a jumble of the signatures of many brain processes. Detecting conscious thoughts like “Shark, please swim forward” is way beyond even state-of-the-art equipment. The electrical signature of a single thought is lost in the furious chatter of 100 billion neurons." So builder Chip Audette settled on the simplest control system he could, and divvied up the actual controls (left, right, forward, etc.) among several users, so each one's brain signals could be interpreted separately. -
An AI Hunts the Wild Animals Carrying Ebola
the_newsbeagle writes: Outbreaks of infectious diseases like Ebola follow a depressing pattern: People start to get sick, public health authorities get wind of the situation, and an all-out scramble begins to determine where the disease started and how it's spreading. Barbara Han, a code-writing ecologist, hopes her algorithms will put an end to that reactive model. She wants to predict outbreaks and enable authorities to prevent the next pandemic. Han takes a big-data approach, using a machine-learning AI to identify the wild animal species that carry zoonotic diseases and transmit them to humans.
