the_newsbeagle writes "Did my head just beep?" wonders a woman who just received a brain implant to treat her intractable epilepsy. We're entering a cyborg age of medicine, with implanted stimulators that send pulses of electricity into the brain or nervous system to prevent seizures or block pain. The first generation of devices sent out pulses in a constant and invariable rhythm, but device-makers are now inventing smart stimulators that monitor the body for signs of trouble and fire when necessary.

wiredmikey writes "Using Apple's voice-activated Siri function, security researchers have managed to steal sensitive information from iOS smartphones in a stealthy manner. Luca Caviglione of the National Research Council of Italy and Wojciech Mazurczy of the Warsaw University of Technology warn that malicious actors could use Siri for stealthy data exfiltration by using a method that's based on steganography, the practice of hiding information. Dubbed "iStegSiri" by the researchers, the attack can be effective because it doesn't require the installation of additional software components and it doesn't need the device's alteration. On the other hand, it only works on jailbroken devices and attackers somehow need to be able to intercept the modified Siri traffic. The attack method involves controlling the "shape" of this traffic to embed sensitive data from the device. This covert channel could be used to send credit card numbers, Apple IDs, passwords, and other sensitive information from the phone to the criminal mastermind, researchers said in their paper.

An anonymous reader writes: IEEE Spectrum reports on a study out of NASA exploring the idea that manned missions to Venus are possible if astronauts deploy and live in airships once they arrive. Since the atmospheric pressure at the surface is 92 times that of Earth, and the surface temperate is over 450 degrees C, the probes we've sent to Venus haven't lasted long. The Venera 8 probe sent back data for only 50 minutes after landing. Soviet missions in 1985 were able to get much more data — 46 hours worth — by suspending their probes from balloons. The new study refines that concept: "At 50 kilometers above its surface, Venus offers one atmosphere of pressure and only slightly lower gravity than Earth. Mars, in comparison, has a "sea level" atmospheric pressure of less than a hundredth of Earth's, and gravity just over a third Earth normal. The temperature at 50 km on Venus is around 75 C, which is a mere 17 degrees hotter than the highest temperature recorded on Earth.

The defining feature of these missions is the vehicle that will be doing the atmospheric exploring: a helium-filled, solar-powered airship. The robotic version would be 31 meters long (about half the size of the Goodyear blimp), while the crewed version would be nearly 130 meters long, or twice the size of a Boeing 747. The top of the airship would be covered with more than 1,000 square meters of solar panels, with a gondola slung underneath for instruments and, in the crewed version, a small habitat and the ascent vehicle that the astronauts would use to return to Venus's orbit, and home."

_Sharp'r_ writes Two Stanford PhDs, Ross Koningstein and David Fork, worked for Google on the RE<C project to figure out how to make renewables cheaper than coal and solve climate change. After four years of study they gave up, determining "Renewable energy technologies simply won't work; we need a fundamentally different approach." As a result, is nuclear going to be acknowledged as the future of energy production?

the_newsbeagle writes In 2007, Google boldly declared a new initiative to invent a green energy technology that produced cheaper electricity than coal-fired power plants. Sure, energy researchers had been hammering at this task for decades, but Google hoped to figure it out in a few years. They didn't. Instead, Google admitted defeat and shut down the project in 2011. In a admirable twist, however, two of the project's engineers then dedicated themselves to learning from the project's failure. What did it mean that one of the world's most ambitious and capable innovation companies couldn't invent a cheap renewable energy tech?

Tekla Perry writes Stealthy 'cinematic reality' company Magic Leap may be based in Florida--but it's doing a lot of hiring from the Bay Area, scooping up engineers from Pixar, Google, Apple, and Intel--along with a few Willow Garage alums. And it's got openings for many many more. Are all these folks with long-term Silicon Valley roots really going to move to South Florida? Or is Magic Leap getting ready to open up a Silicon Valley research center to house the brain trust it is gathering? Here's what we know about Magic Leap and its technology, who's joining it, and what other kinds of engineers the company aims to hire. Magic Leap has a lot of money to do all that hiring, having just raised more than half a billion dollars, the bulk of it from Google. If you're working in the Bay Area now, would you look forward to a move to Florida, or rather stay where you are?

RockDoctor writes: Reuters reports that there are changes afoot for life insurance contracts, which will require additional premiums for "space tourists." While not likely to be a disabling issue for the industry — the statistics for astronauts dying in flight are not that bad — it is an issue that people considering such a jaunt will need to address. Obviously this has been brought to the fore by the unfortunate crash of the Virgin Galactic craft under test. Relatedly, an article at IEEE Spectrum explains why SpaceShipTwo's rocket fuel wasn't the cause of the accident.

the_newsbeagle writes: In the latest high-tech approach to personalized medicine, cardiologists can now create a computer model of an individual patient's heart and use that simulation to make a treatment plan. In this new field of computational medicine, doctors use a patient's MRI scans to make a model showing that patient's unique anatomy and pattern of heart disease. They can then experiment on that virtual organ in ways they simply can't with a flesh-and-blood heart. Proponents say this tech can "improve therapies, minimize the invasiveness of diagnostic procedures, and reduce health-care costs" in cardiology.

First time accepted submitter agent elevator writes In a wide-ranging interview at IEEE Spectrum, Michael I. Jordan skewers a bunch of sacred cows, basically saying that: The overeager adoption of big data is likely to result in catastrophes of analysis comparable to a national epidemic of collapsing bridges. Hardware designers creating chips based on the human brain are engaged in a faith-based undertaking likely to prove a fool's errand; and despite recent claims to the contrary, we are no further along with computer vision than we were with physics when Isaac Newton sat under his apple tree.

szotz writes Nick Holonyak Jr. doesn't want to go gently into that good night. Widely regarded as the father of the LED (for his work on early visible-light devices), he's been making strongly-worded comments about being passed over for the Nobel Prize. His wife said he'd given up on getting it. But, he says, this year's physics award, to inventors of the blue LED, was just plain 'insulting'. The history the LED goes beyond and back further than Holonyak (all the way to the beginning of the 20th century), but a number of his colleagues are disappointed and/or surprised by the snub.

HughPickens.com writes "Jeremy Hsu reports that the U.S. Navy has been testing a large-scale swarm of autonomous boats designed to overwhelm enemies. In the test, a large ship that the Navy sometimes calls a high-value unit, HVU, is making its way down the river's thalweg, escorted by 13 small guard boats. Between them, they carry a variety of payloads, loud speakers and flashing lights, a .50-caliber machine gun and a microwave direct energy weapon or heat ray. Detecting the enemy vessel with radar and infrared sensors, they perform a series of maneuvers to encircle the craft, coming close enough to the boat to engage it and near enough to one another to seal off any potential escape or access to the ship they are guarding. They blast warnings via loudspeaker and flash their lights. The HVU is now free to safely move away.

Rear Adm. Matthew Klunder, chief of the Office of Naval Research, points out that a maneuver that required 40 people had just dropped down to just one. "Think about it as replicating the functions that a human boat pilot would do. We've taken that capability and extended it to multiple [unmanned surface vehicles] operating together within that, we've designed team behaviors," says Robert Brizzolara. The timing of the briefing happens to coincide with the 14-year anniversary of the bombing of the USS Cole off the coast of Yemen that killed 17 sailors. It's an anniversary that Klunder observes with a unique sense of responsibility. "If we had this capability there on that day. We could have saved that ship. I never want to see the USS Cole happen again."

HughPickens.com writes: Markus Krajewski reports that today, with many countries phasing out incandescent lighting in favor of more-efficient and pricier LEDs, it's worth revisiting the history of the Phoebus cartel — not simply as a quirky anecdote from the annals of technology, but as a cautionary tale about the strange and unexpected pitfalls that can arise when a new technology vanquishes an old one. Prior to the Phoebus cartel's formation in 1924, household light bulbs typically burned for a total of 1,500 to 2,500 hours; cartel members agreed to shorten that life span to a standard 1,000 hours.

Each factory regularly sent lightbulb samples to the cartel's central laboratory in Switzerland for verification. If any factory submitted bulbs lasting longer or shorter than the regulated life span for its type, the factory was obliged to pay a fine. Though long gone, the Phoebus cartel still casts a shadow today because it reduced competition in the light bulb industry for almost twenty years, and has been accused of preventing technological advances that would have produced longer-lasting light bulbs. Will history repeat itself as the lighting industry is now going through its most tumultuous period of technological change since the invention of the incandescent bulb?

"Consumers are expected to pay more money for bulbs that are up to 10 times as efficient and that are touted to last a fantastically long time—up to 50,000 hours in the case of LED lights. In normal usage, these lamps will last so long that their owners will probably sell the house they're in before having to change the bulbs," writes Krajewski. "Whether or not these pricier bulbs will actually last that long is still an open question, and not one that the average consumer is likely to investigate." There are already reports of CFLs and LED lamps burning out long before their rated lifetimes are reached. "Such incidents may well have resulted from nothing more sinister than careless manufacturing. But there is no denying that these far more technologically sophisticated products offer tempting opportunities for the inclusion of purposefully engineered life-shortening defects.""

HizookRobotics writes Georgia Tech researchers announced a new way robots can "sense" their surroundings through the use of small ultra-high frequency radio-frequency identification (UHF RFID) tags. Inexpensive self-adhesive tags can be stuck on objects, allowing an RFID-equipped robot to search a room for the correct tag's signal, even when the object is hidden out of sight. Once the tag is detected, the robot knows the object it's trying to find isn't far away. The researchers' methods, summarized over at IEEE: "The robot goes to the spot where it got the hottest signal from the tag it was looking for, zeroing in on it based on the signal strength that its shoulder antennas are picking up: if the right antenna is getting a stronger signal, the robot yaws right, and vice versa."

the_newsbeagle writes: One of the leading companies developing wave power devices, Ocean Power Technologies, has dramatically scaled down its ambitions. The company had planned to install the world's first commercial-scale wave farms off the coast of Australia and Oregon, but has now announced that it's ending those projects. Instead it will focus on developing next-gen devices. Apparently the economics of wave power just don't make sense yet.

An anonymous reader writes "IEEE Spectrum contributor Mark Harris obtained a copy of the DMV test Google's autonomous car passed in Nevada in 2012 and associated documents. What has not been revealed until now, is that Google chose the test route; that it set limits on the road and weather conditions that the vehicle could encounter; and that its engineers had to take control of the car twice during the drive.

An anonymous reader writes: A debate has been raging recently over whether or not to equip police with body cameras so that instances of violence in the line of duty can be monitored. It's an important discussion to have, but we should also look at other technologies that could help provide hard data on gun incidents. A new paper was recently published in PLOS ONE about the use of wristband accelerometers to detect when the wearer has fired a gun. Study author and criminology professor Charles Loeffler said, "A gunshot is pretty distinctive. You're typically at rest because you're trying to aim, and in a split second, your hand, wrist, and arm experience an impulsive transfer of energy." Loeffler suggests a suite of sensors including GPS and the wristband accelerometer could be given to convicts as a requirement for their parole. Not only would this help with police response in case of recidivism, but it could provide additional deterrent to further crimes. It could also be helpful to police departments, both for accountability and for integration between the police and the courts.

Tekla Perry (3034735) writes "Scott Hassan, founder of robotic research lab Willow Garage, is behind a large real estate development in Menlo Park, Calif. He reportedly plans to create an incubator village with 18,500 square meters of workspace and another 18,500 square meters of living space on a 30,000 square meter site, combining the advantages of a garage startup environment (what could be more convenient than working where you live) and an incubator (access to other smart entrepreneurs and ideas)." Would you want to live in this kind of environment?

aarondubrow writes: We're entering an era where we'll increasingly coexist with robots and other intelligent machines — some of which may look like us. Not only is there a growing number of industrial robots (about 1.5 million today), there are 10 million Roombas in our homes, porter-bots in our hospitals and hotels, social robots in our nursing homes and even robot spectators at baseball games in Japan, tele-operated by remote fans.

Theater is not an arena that we typically associate with robots, however, artists, musicians and producers are often early adopters and innovative users of emerging technologies. In fact, robots got their name from the 1920 play, R.U.R., by the Czech playwright, Karel Capek. An article in the Huffington Post describes a panel discussion at the National Academy of Science in June that featured the producers of three recent plays that starred robots. The plays highlight our robot anxieties, while offering new visions for human-robot interactions in the future.

msm1267 writes: The IEEE's Center for Secure Design debuted its first report this week, a guidance for software architects called "Avoiding the Top 10 Software Security Design Flaws." Developing guidance for architects rather than developers was a conscious effort the group made in order to steer the conversation around software security away from exclusively talking about finding bugs toward design-level failures that lead to exploitable security vulnerabilities. The document spells out the 10 common design flaws in a straightforward manner, each with a lengthy explainer of inherent weaknesses in each area and how software designers and architects should take these potential pitfalls into consideration.

the_newsbeagle writes: To make a brain-machine interface, you need a way to capture neurons' electric signals. The most precise and most invasive way uses implants that are stuck in the gray matter. The least precise and least invasive way uses EEG sensors stuck to the scalp. But researchers at Johns Hopkins University say there's a third way that gets the best of both worlds, which is not too invasive and fairly precise. They use ECoG systems, in which a mesh of electrodes is placed under the skull, draped over the surface of the cortex.

They're testing their systems on epilepsy patients, who have these ECoG systems inserted anyway while they're waiting for surgery (the electrodes record the source of their seizures). The researchers are capturing these patients' movement commands from their brains, and using them to control robotic limbs. Someday such a system could be used by amputees to control their prosthetic limbs.

An anonymous reader writes "Researchers at Harvard's Self-Organizing Systems Research Group—describe their thousand-robot swarm in a paper published today in Science (they actually built 1024 robots). In the past, researchers have only been able to program at most a couple hundred robots to work together. Now, these researchers have programmed the biggest robot swarm yet. Alone, the simple little robot can't do much, but working with 1,000 or more like-minded fellow bots, it becomes part of a swarm that can self-assemble into any two-dimensional shape. These are some of the first steps toward creating huge herds of tiny robots that form larger structures—including bigger robots."

the_newsbeagle writes If you've been hankering to control a robotic battle spider with your mind but haven't known how to begin, you're in luck. A startup called OpenBCI is now selling an Arduino-compatible board that any reasonably competent DIYer can use to build a brain-computer interface. The board takes in data from up to 8 EEG scalp electrodes, and hackers are already using it to pull of some good tricks. There's the guy with the battle spiders, and there's a group in L.A. building a paint-by-brain system for a paralyzed graffiti artist.

New submitter IMissAlexChilton (3748631) writes Frank Malina masterfully led the World War II effort to build U.S. rockets for jet-assisted takeoff and guided missiles. As described in IEEE Spectrum, Malina's motley crew of engineers and enthusiasts (including occultist Jack Parsons) founded the Jet Propulsion Lab and made critical breakthroughs in solid fuels, hypergolics, and high-altitude sounding rockets, laying the groundwork for NASA's future successes. And yet, under suspicion by the Feds at the war's end, Malina gave up his research career, and his team's efforts sank into obscurity. Taking his place: the former Nazi Wernher von Braun.

Gaza, already short on electricity despite imports from Israel and Egpyt, now faces widening blackouts."

Tekla Perry (3034735) writes The 'Weissman Score' — created for HBO's "Silicon Valley" to add dramatic flair to the show's race to build the best compression algorithm — creates a single score by considering both the compression ratio and the compression speed. While it was created for a TV show, it does really work, and it's quickly migrating into academia. Computer science and engineering students will begin to encounter the Weissman Score in the classroom this fall."

Tekla Perry (3034735) writes Professor Tsachy Weissman and Ph.D student Vinith Misra came up with (almost) believable compression algorithms for HBO's Silicon Valley. Some constraints -- they had to seem plausible, look good when illustrated on a whiteboard, and work with the punchline, "middle out." Next season the engineers may encourage producers to tackle the challenge of local decodability.

rtoz writes Researchers from Seoul National University have designed a robotic wheel based on the origami "magic ball pattern," which is a traditional technique used to create folded paper spheres. This robotic wheel can change its radius to create larger wheels to climb over things, and shrink back to a smaller size to squeeze under obstacles. The diameter of the wheels changes automatically to enable the robot to either be strong or speedy. The scientists think their innovation could one day be used for interplanetary rovers as the wheel can be folded up and "inflate" itself.

JeremyHsu writes: A one-second delay can still seem like an eternity for a quantum computing machine capable of running calculations in mere millionths of a second. That delay represents just one of the challenges D-Wave Systems overcame in building its second-generation quantum computing machine known as D-Wave Two — a system that has been leased to customers such as Google, NASA and Lockheed Martin. D-Wave's rapid-scaling approach to quantum computing has plenty of critics, but the company's experience in building large-scale quantum computing hardware could provide valuable lessons for everyone, regardless of whether the D-Wave machines live up to quantum computing's potential by proving they can outperform classical computers. (D-Wave recently detailed the hardware design changes between its first- and second-generation quantum computing machines in the the June 2014 issue of the journal IEEE Transactions on Applied Superconductivity.)

"We were nervous about going down this path," says Jeremy Hilton, vice president of processor development at D-Wave Systems. "This architecture requires the qubits and the quantum devices to be intermingled with all these big classical objects. The threat you worry about is noise and impact of all this stuff hanging around the qubits. Traditional experiments in quantum computing have qubits in almost perfect isolation. But if you want quantum computing to be scalable, it will have to be immersed in a sea of computing complexity.

Lofty goals: "To start, DARPA will support the development of multi-scale computational models with high spatial and temporal resolution that describe how neurons code declarative memories — those well-defined parcels of knowledge that can be consciously recalled and described in words, such as events, times, and places. Researchers will also explore new methods for analysis and decoding of neural signals to understand how targeted stimulation might be applied to help the brain reestablish an ability to encode new memories following brain injury. ... Building on this foundational work, researchers will attempt to integrate the computational models ... into new, implantable, closed-loop systems able to deliver targeted neural stimulation that may ultimately help restore memory function."

Tekla Perry writes: We cook our food today using technology invented to bake bricks. We can do a lot better. Nathan Myhrvold explains what's wrong with today's ovens and challenges oven designers make them better. He says, "Oven designers could do a lot to make ovens heat more evenly by taking advantage of the different ways ovens transfer heat at different cooking temperatures. At 200 C or below, convection moves most of the heat. But at 400 C, radiant energy starts doing a fair amount of the heat transfer. At 800 C, radiation overwhelms convection. Why couldn't we have an oven designed to cook primarily by convection at low temperatures that switches to radiant heating for high-temperature baking? ... The shiny skin of raw fish reflects heat, but as the skin browns, it reflects less and less energy. That’s why food under a broiler can seem to cook slowly at first and then burn in the blink of an eye. But technology offers a fix here, too. Oven designers could put optical sensors in the oven chamber to sense the reflectivity of the food, and then the oven controller could adjust the heat automatically or at least alert the cook as the surface browns. And a camera in the oven could feed to a color display on the front panel, giving the chef a clearer view of the food than a small window in the door can. Indeed, a decent optics system could allow designers to dispense with the glass in the door altogether, reducing the gap between the hottest and coolest corners of the oven and obviating the need to open the door and rotate the food midway through cooking.

In the past, the FAA had made the distinction between model aircraft (allowed) and drones (prohibited without special permission) according to whether they were used for recreation (okay) or commercial purposes (verboten). Now they have further narrowed the definition of model aircraft: If you fly it through video goggles, it no longer qualifies. This move eliminates First Person View (FPV) radio control flying. I'm an editor at IEEE Spectrum with a special interest and blogged about this disturbing development as soon as I heard the news."

MojoKid (1002251) writes The transistor is one of the most profound innovations in all of human existence. First discovered in 1947, it has scaled like no advance in human history; we can pack billions of transistors into complicated processors smaller than your thumbnail. After decades of innovation, however, the transistor has faltered. Clock speeds stalled in 2005 and the 20nm process node is set to be more expensive than the 28nm node was for the first time ever. Now, researchers at NASA believe they may have discovered a way to kickstart transistors again — by using technology from the earliest days of computing: The vacuum tube. It turns out that when you shrink a Vacuum transistor to absolutely tiny dimensions, you can recover some of the benefits of a vacuum tube and dodge the negatives that characterized their usage. According to a report, vacuum transistors can draw electrons across the gate without needing a physical connection between them. Make the vacuum area small enough, and reduce the voltage sufficiently, and the field emission effect allows the transistor to fire electrons across the gap without containing enough energy to energize the helium inside the nominal "vacuum" transistor. According to researchers, they've managed to build a successful transistor operating at 460GHz — well into the so-called Terahertz Gap, which sits between microwaves and infrared energy.

the_newsbeagle writes Psychiatrists have realized that they can collect vast amounts of data about their patients using smartphone apps that passively monitor the patients as they go about their daily business. A prototype for schizophrenia patients is being tested out now on Long Island. The Crosscheck trial will look at behavior patterns (tracking movement, sleep, and conversations) and correlate them with the patient's reports of symptoms and moods; researchers hope the data will reveal the "signature" of a patient who is about relapse and therefore needs help.

Their goal is to launch an open-source hardware movement in neuroscience, so researchers can spend less time worrying about the gear they need and more time doing experiments."

It does that by monitoring two inertial measurement units (IMUs) that the user wears on the wrists. A third IMU sits at the base of the robot's shoulder mount, to track the overall orientation and motion of the SRL." In the future, we will all have the ability to become Doctor Octopus (minus two robo-limbs, of course).'

We have to find a way to exploit space resources and cut down on the amount of stuff we need to launch from Earth. That's not a new idea. But this article in IEEE Spectrum suggests research on resource extraction and fabrication in low and zero gravity might actually be making progress...and that we could take these technologies quite far if we get our act together."

Bunnie Huang is both a hardware and software hacker, but that's greatly understating the case: renaissance man is more like it. Bunnie doesn't just tinker with one-off system modifications or console mods (though he's done that, too) -- he creates and repurposes at scale. (He's also an author, respected researcher with interesting thoughts on a wide range of topics, like how to think of the H1N1 flu from the point of view of a security researcher.) Bunnie's latest long-term project has been mentioned a few times on Slashdot: It's an open-source laptop computer that goes much farther than some other open-source hardware projects, and as a bonus includes an FPGA as well as a conventional -- but unusual -- processor. (Bunnie grants that there are still bits that aren't quite open source, but points out that we also don't have the software that runs the fabs; there's a point of diminishing returns.) A crowd funding campaign (via CrowdSupply) was successful enough to also fund several stretch goals, including a general purpose breakout board. I talked with Bunnie at the recent Bay Area Maker Faire. (Expect more from that show in coming weeks.) He walked us through the state of the hardware, and talked about some of the design decisions that go into making a computer that is of, by, and for hackers. (Alternate video link)

The article spotlights the visionaries Hugh Herr, an MIT professor (and double amputee) who wants to build prosthetic limbs that are wired directly into the nervous system; Helen Mayberg, who has developed brain pacemakers to cure depression; and Ted Berger, who's working on neural implants that can restore memory function."

the_newsbeagle writes "People who are into the quantified health trend can already measure and chart a wide variety of metrics — steps taken, calories burned, heart rate, blood pressure, sleep patterns, etc can all be tracked using new gadgets. Now a new device called Cue lets people track their biochemical stats, too. Cue offers five DIY lab tests, automates the testing procedure, and sends the results to the user's smartphone. It lets guys check their testosterone levels, ladies check their fertility status, and also offers tests for the flu virus, vitamin D levels, and an inflammation-marker protein. Apparently more tests are expected down the line."

kelk1 sends this article from the Stanford News Service: "Stanford bioengineers have developed faster, more energy-efficient microchips based on the human brain – 9,000 times faster and using significantly less power than a typical PC (abstract). Kwabena Boahen and his team have developed Neurogrid, a circuit board consisting of 16 custom-designed 'Neurocore' chips. Together these 16 chips can simulate 1 million neurons and billions of synaptic connections. The team designed these chips with power efficiency in mind. Their strategy was to enable certain synapses to share hardware circuits. ... But much work lies ahead. Each of the current million-neuron Neurogrid circuit boards cost about $40,000. (...) Neurogrid is based on 16 Neurocores, each of which supports 65,536 neurons. Those chips were made using 15-year-old fabrication technologies. By switching to modern manufacturing processes and fabricating the chips in large volumes, he could cut a Neurocore's cost 100-fold – suggesting a million-neuron board for $400 a copy."

Everyone thinks it's a cool idea to collect solar power 24 hours a day and beam it down to Earth. But what with the expense and difficulty of rocketing up the parts and constructing and operating the stations in orbit, nobody's built one yet. While you probably still shouldn't hold your breath, it's interesting to learn that Japan's space agency has spec'd out such a solar power station."
