The Inside Story of Virgin Oceanic's Mission To the Mariana Trench
the_newsbeagle writes "Millionaire adventurer Chris Welsh, the driving force behind Virgin Oceanic, wants to name his sub "Scarlett" after Scarlett Johansson—that's how sexy this vehicle is. Welsh plans to pilot the experimental, cutting-edge sub to the bottom of the Mariana Trench sometime this year, in what would be only the second human descent to the deepest spot in the world's oceans (the first trip down was in 1960). This inside account of the Virgin Oceanic mission describes a team fueled by ego, science, and derring-do, and explains how their high-tech sub could usher in a new kind of marine exploration. The article also tells the story of an adventure on the high seas last summer, when Welsh & co visited the trench to test some robotic deep-sea landers... and ran smack into a typhoon." -

DARPA Researches Avatar Surrogates
kgeiger writes "Feeling blue? DARPA is funding a program to investigate the feasibility of battlefield cyborg-surrogates: 'In its 2012 budget, DARPA has decided to pour US $7 million into the 'Avatar Project,' whose goal is the following: "develop interfaces and algorithms to enable a soldier to effectively partner with a semi-autonomous bi-pedal machine and allow it to act as the soldier's surrogate."' Power and bandwidth constraints aside, what could go wrong? Chinese hackers swooping in and commandeering one's army?" -
Web Guru To the Blind
the_newsbeagle writes "Chieko Asakawa went blind at age 14, learned to program mainframe computers by sense of touch, and has spent her 27 years at IBM-Tokyo bringing personal computing and the Internet to the blind. From the article: 'By 1997 she had developed a plug-in that worked with the Netscape browser, mapping Web navigation commands to the computer keyboard's number pad and using text-to-speech technology to read out content. Computer stores around the world sold IBM's Home Page Reader, and Asakawa says its effect on the blind community was immediate, electric, and sometimes touching. ... Other browsers for the blind followed IBM's groundbreaking efforts, and Asakawa moved on to addressing a deeper problem: the fact that designers were unintentionally creating inaccessible websites. She and her team wrote a program called aDesigner ... to allow designers to experience a site as blind users do and to suggest ways to improve navigation for audio browsers.'" -
US 'Space Warplane' Spying On Chinese Spacelab
PolygamousRanchKid sends this excerpt from El Reg: "The U.S. Air Force's second mysterious mini-space shuttle, the X-37B, could be spying on China's space laboratory and the first piece of its space station, Tiangong-1. Amateur space trackers told the British Interplanetary Society publication Spaceflight that the black-funded spaceplane seemed to be orbiting the Earth in tandem with Tiangong-1, or the Heavenly Palace, leading the magazine to speculate that its unknown mission is to spy on [the lab]. ... The lab is unmanned for the moment, so all there'd be to study is the technology of the craft and what experiments it's doing. Still, the U.S. is hugely suspicious of China's space endeavors, so it's more than possible that they'd want to get a look at Tiangong-1 just in case it's doing anything unexpected." Update: 01/06 21:50 GMT by S : Further calculations have shown that this is not the case after all. -
Ohm's Law Survives To the Atomic Level
Hugh Pickens writes "Moore's Law, the cornerstone of the semiconductor industry, may get a reprieve from its predicted demise. As wires shrink to just nanometers in diameter, their resistivity tends to grow exponentially, curbing their usefulness as current carriers. But now a team of researchers has shown that it is possible to fabricate low-resistivity nanowires at the smallest scales imaginable by stringing together individual atoms in silicon as small as four atoms (about 1.5 nanometers) wide and a single atom tall. The secret is to introduce phosphorus along that line because each phosphorus atom donates an electron to the silicon crystal, which promotes electrical conduction. They then encase the nanowires entirely in silicon, which makes the conduction electrons more immune to outside influence. By embedding phosphorus atoms within a silicon crystal with an average spacing of less than 1 nanometer, the team achieved a diameter-independent resistivity, which demonstrates ohmic scaling to the atomic limit. 'That moves the wires away from the surfaces and away from other interfaces,' says physicist says Michelle Simmons. 'That allows the electron to stay conducting and not get caught up in other interfaces.' The wires have the carrying capacity of copper, indicating that the technique might help microchips continue their steady shrinkage over time and may even extend the life of Moore's Law. 'Fundamentally, we have shown that we can maintain low resistivities in doped silicon wires down to the atomic scale,' says Simmons, adding that it may not be ready for production now, but, 'who knows 20 years from now?'" -
Instead of a Wheel Chair, How About an Exoskeleton?
New submitter the_newsbeagle writes "This year, Ekso Bionics will roll out its most sophisticated exoskeleton ever. The company's robotic walking suit, called the Ekso, allows paraplegics to get back on their feet and walk on their own. The first commercial model will be sold to rehab hospitals for on-site physical therapy, but the company plans to have a model ready for at-home physical therapy by the end of 2012. In a few years, they plan to sell an Ekso that a paraplegic person can wear to the post office, to work, etc." -
Experimenting With Robotic Movement
kodiaktau writes "Roboticists with EPFL are playing with new methods of locomotion for robots, modeled after grasshoppers, bats and other non-traditional forms of movement, including leaping and gliding." -
Domestic Surveillance Drones Could Spur Tougher Privacy Laws
An anonymous reader writes "Have you ever been spied on by a surveillance drone? No? Are you sure? Maybe it looked like a hummingbird. Or an insect. Or maybe it was just really high up. Maybe there's one looking in your window right now, and if so, there's no law that says it shouldn't. In a recent article in the Stanford Law Review, Ryan Calo discusses how domestic surveillance drones would fit into the current legal definitions of privacy (and violations thereof), and how these issues could inform the future of privacy policy. The nutshell? Surveillance robots have the potential to fundamentally degrade privacy to such an extent that they could serve as a catalyst for reform." -
The Strange Birth and Long Life of Unix
riverat1 writes "After AT&T dropped the Multics project in March of 1969, Ken Thompson and Dennis Ritchie of Bell Labs continued to work on the project, through a combination of discarded equipment and subterfuge, eventually writing the first programming manual for System I in November 1971. A paper published in 1974 in the Communications of the ACM on Unix brought a flurry of requests for copies. Since AT&T was restricted from selling products not directly related to telephones or telecommunications, they released it to anyone who asked for a nominal license fee. At conferences they displayed the policy on a slide saying, 'No advertising, no support, no bug fixes, payment in advance.' From that grew an ecosystem of users supporting users much like the Linux community. The rest is history." -
4 Wave Gliders Begin Their Autonomous Pacific Crossing Attempt
In 2009, an autonomous ocean glider bobbed and dipped its way across the Atlantic; now, reader cylonlover writes with word that "Four small autonomous aquatic robots have embarked on a 60,000-kilometer (37,000-mile) journey across the Pacific ocean. The Wave Gliders, built by California-based Liquid Robotics, left San Francisco last Thursday." Two of the robot craft are to head to Australia, the other two to Japan. According to the IEEE description, "Waves will power their propulsion systems and the sun will power the sensors that will be measuring things like water salinity, temperature, clarity, and oxygen content; collecting weather data, and gathering information on wave features and currents." -
Robot Controls Person's Arm To Manipulate Objects
An anonymous reader writes "French researchers have demonstrated a robot that controls its own arm as well as a person's arm to manipulate objects in a collaborative manner, IEEE reports. Electrodes attached to the person's arm allow the robot to make the elbow and hand move to perform tasks. The tasks are currently simple (dropping a ball through a hoop, as shown in one of their videos), but the researchers say more complex ones are possible. They also say the approach has therapeutic benefits and their goal is to 'develop robotic technologies that can help people suffering from paralysis and other disabilities to regain some of their motor skills.'" -
Did Fracking Cause Recent Oklahoma Earthquakes?
Hugh Pickens writes writes "Oklahoma is typically seismically stable, with about 50 small quakes a year — but in 2009, that number jumped up to more than 1,000 and on November 5 a 5.6-magnitude tremor rattled Oklahoma — one of the strongest to ever hit the state — leading scientists to wonder if the increasingly common use of fracking, the controversial practice of blasting underground rock formations with high-pressure water, sand, and chemicals to extract natural gas, may have put stress on fault lines. Human intervention has caused earthquakes before with one 'textbook case' occurring in 1967 in India, says Peter Fairley at IEEE Spectrum, when the reservoir behind the hydroelectric Koyna Dam was filled up. The added water 'unleashed a magnitude 6.3 quake' by placing stress 'on a previously unknown fault, killing 180 people and leaving thousands homeless.' Last week's earthquakes and aftershocks are centered in rural Lincoln County, in an area about 30 miles east of Oklahoma City and there are 181 injection wells In Lincoln County. But a recent study by Austin Holland, a seismologist with the Oklahoma Geological Survey, says that it's possible that hydraulic fracking caused a series of small earthquakes, peaking at 2.8, in an area south of Oklahoma City but doesn't believe fracking caused the big Nov. 5, 6 and 8 earthquakes comparing a man-made earthquake to a mosquito bite. 'It's really quite inconsequential,' says Holland." -
The Transistor Wars
An anonymous reader writes "This article has an interesting round-up of how chipmakers are handling the dwindling returns of pursuing Moore's Law. Intel's about four years ahead of the rest of the semiconductor industry with its new 3D transistors. But not everyone's convinced 3D is the answer. 'There's a simple reason everyone's contemplating a redesign: The smaller you make a CMOS transistor, the more current it leaks when it's switched off. This leakage arises from the device's geometry. A standard CMOS transistor has four parts: a source, a drain, a channel that connects the two, and a gate on top to control the channel. When the gate is turned on, it creates a conductive path that allows electrons or holes to move from the source to the drain. When the gate is switched off, this conductive path is supposed to disappear. But as engineers have shrunk the distance between the source and drain, the gate's control over the transistor channel has gotten weaker. Current sneaks through the part of the channel that's farthest from the gate and also through the underlying silicon substrate. The only way to cut down on leaks is to find a way to remove all that excess silicon.'" -
New, More Autonomous Asimo Robot Unveiled By Honda
An anonymous reader writes "Honda has just unveiled a new, upgraded version of its famous humanoid robot, Asimo. Its appearance didn't change much, but the new robot is lighter, faster, and stronger. It can walk on uneven surfaces, run backwards, and even jump on one foot. The new Asimo also has more dexterous hands and better image and voice recognition to interact with people. Honda's big push is clearly in the direction of making Asimo more autonomous, and useful, in human environments." -
Blow-By-Blow Account of the Fukushima Accident
An anonymous reader writes "In the first few days of the Fukushima Daiichi nuclear accident, no one outside the power station knew what the hell was happening. In the 9 months since, information has come out in confusing bits and pieces. Now, finally, we have an authoritative account of exactly what went wrong in the first 24 hours of the accident. It's a harrowing tale of creativity, heroism, and catastrophe. One thing I hadn't realized was just how close workers came to averting the worst nuclear disaster since Chernobyl." -
Boston Dynamics' PETMAN Humanoid On Video
An anonymous reader writes "IEEE reports that Boston Dynamics has unveiled video footage showing its biped humanoid robot PETMAN walking, kneeling, and doing push-ups. Boston Dynamics is building the robot for the U.S. Army, which will use it to test chemical protective suits for soldiers. The requirement was that the robot had to be the approximate size of a 50th percentile adult male (180 pounds, nearly 6 feet tall) and capable of a full range of dynamic movements. The company says PETMAN could also be used to survey disaster zones and access hazardous environments." -
Agile Quadruped Robot Unveiled By Italian Roboticists
An anonymous reader writes "Italian roboticists have built a quadruped robot called HyQ that can walk, trot, jump, and rear. Unlike with another quadruped project, the famous BigDog from Boston Dynamics, the Italian team wants to make their design 'as open as possible,' so other research groups can use it to collaborate. HyQ is a hydraulic system with torque-controlled, compliant legs. It's currently tethered, but the researchers plan to make the robot self-contained with an on-board pump, add a head with cameras and laser-range finder, and take it for tests outdoors." -
How Google's Autonomous Vehicles Work
An anonymous reader writes "IEEE reports that Google's autonomous cars have logged more than 190,000 miles driving in all kinds of traffic, and the company is also testing a fleet of self-driving golf carts on its campus. In a recent talk, Sebastian Thrun and Chris Urmson of Google gave details of the project and showed videos of the robot cars driving themselves and even doing some stunts. The goal is that the technology will help reduce congestion, fuel waste, and accidents." -
Boston Dynamics Unveils AlphaDog Quadruped Robot
An anonymous reader writes "Boston Dynamics, the company that created the BigDog quadruped robot, has unveiled a new, bigger system called AlphaDog. AlphaDog, a DARPA-sponsored project, can carry a payload of 400 pounds for up to 20 miles without having to refuel, and it's also much quieter than BigDog. The robot is designed to assist humans in carrying heavy equipment over rough terrain, and Boston Dynamics' schedule has the first walk-out of AlphaDog taking place sometime in 2012, when U.S. Marines will begin to put the robot to the test for real." -
Chinese Submersible Planning For Record Dive
An anonymous reader writes "You may have heard that China sent a manned research sub down to the ocean deep this summer, marking a personal depth record of 5,000 meters (next year it will aim for a world record of 7,000 meters). Here's a story about the sub based on an interview with its designer in Wuxi, China. It's got some interesting new details: the designer had never actually seen a submersible before he set out to build the deepest diving research sub in the world; all the stuff he's built before has ended up in warehouses because the Chinese government only funded technological development, not use." -
Fukushima Robot Operator Tells His Story
An anonymous reader writes "An anonymous robot operator at Japan's Fukushima nuclear plant has kept a blog describing in candid detail his day-to-day life at the crippled facility, including robot training exercises and actual radiation-survey and clean-up missions. The blog was recently deleted, but some copies existed around the web and IEEE Spectrum has translated and published portions of it in English. The blog shows that although the operators use remote-controlled robots, they have to work in areas of high radiation, using protective gear and shielded trucks. They also rely on a great deal of improvisation, and there have been a few incidents that put the robot missions at risk." -
Floating Nuclear Power Plant Seized By Court
An anonymous reader writes "The world's first nuclear barge has been impounded while still under construction — but not because of looming safety or environmental concerns. The shipyard's parent companies are embroiled in bankruptcy proceedings, and Russia's state nuclear corporation, Rosatom, was worried that a creditor would end up with this valuable nuclear asset, and asked the bankruptcy court to seize the barge to protect it." -
Stanford 'Intro To AI' Course Offered Free Online
An anonymous reader writes "IEEE Spectrum reports that Stanford's CS221 course 'Introduction to Artificial Intelligence' will be offered online for free. Anyone can sign up and take the course, along with several hundred Stanford undergrads. The instructors are Sebastian Thrun, known for his self-driving cars, and Peter Norvig, director of research at Google. Online students will actually have to do all the same work as the Stanford students. There will be at least 10 hours per week of studying, along with weekly graded homework assignments and midterm and final exams. The instructors, who will be available to answer questions, will issue a certificate for those who complete the course, along with a final grade that can be compared to the grades of the Stanford students. The course, which will last 10 weeks, starts on October 2nd, and online enrollment is now open." When asked how they would deal with ten thousand students, Professor Thrun replied: "We will use something akin to Google Moderator to make sure Peter and I answer the most pressing questions. Our hypothesis is that even in a class of 10,000, there will only be a fixed number of really interesting questions (like 15 per week). There exist tools to find them." -
Evaluating the Capabilities of Chip-Sized Spacecraft
kgeiger writes "The Sprite project is testing the feasibility of chip-sized spacecraft. 'Rather than hand building one-of-a-kind spacecraft, we envision constructing spacecraft on wafers in much the same way that common integrated circuits are made today. During fabrication, solar cells and other components would be incorporated with microelectromechanical systems techniques. Instead of exhaustively testing each part, as is done with current spacecraft, engineers will be able to monitor Sprite quality in a less labor-intensive fashion by using statistical process control, testing a few chips from each batch to make sure they meet specifications.' The project's goal is to deploy true 'smart dust,' comprised of 5- to 50-mg single-sensor spacecraft capable of forming deep-space sensor arrays." -
Robot Helps Quadriplegic Scratch an Itch
An anonymous reader writes "Georgia Tech's Healthcare Robotics Lab and Willow Garage have been collaborating with Henry Evans, who became a mute quadriplegic after suffering a stroke 10 years ago, to use a PR2 robot as his surrogate. The robot is allowing him to do things like shave himself and scratch itches when he has them, things for which he's been dependent on other people. Henry uses a head tracker to directly move the robot's body, including its arms and head, or invoke autonomous actions, such as navigating in a room or fetching objects. The researchers hope personal robots will allow people with severe physical disabilities to live better and gain more independence." -
Novel Drive Wheel System Based On Spinning Sphere
An anonymous reader writes "A Bradley University student has built a mobile robot that uses a hemispherical omnidirectional gimbaled, or HOG, drive wheel. It consists of a black rubber hemisphere that rotates like a spinning top, with servos that can tilt it left and right and forwards and backwards. The HOG system delivers an amount of torque directly proportional to the tilt of the hemisphere, allowing the robot to move incredibly fast nearly instantaneously." -
Fusion Thrusters For Space Travel
kgeiger writes "John J. Chapman, a physicist and electronics engineer at NASA's Langley Research Center, envisions a laser-pumped fusion drive. Chapman estimates the drive can produce thrust 40 times more efficiently than existing ion engines such as those on the Dawn mission now exploring the asteroid belt." -
Kilobots — Cheap Swarm Robots Out of Harvard
An anonymous reader writes with news of a research project at Harvard into controlling large swarms of small robots. This article describes what they call Kilobots. (Which, for clarity's sake, have nothing to do with killing. Yet.) Quoting: "They're fairly simple little robots about the size of a quarter that can move around on vibrating legs, blink their lights, and communicate with each other. On an individual basis, this isn't particularly impressive, but Kilobots aren't designed to be used on an individual basis. Costing a mere $14 each and buildable in about five minutes, you don't just get yourself one single Kilobot. Or ten. Or a hundred. They're designed to swarm in the thousands." -
IBM Builds First Graphene Integrated Circuit
AffidavitDonda writes "IBM researchers have built the first integrated circuit (IC) based on a graphene transistor. The circuit, built on a wafer of silicon carbide, consists of field-effect transistors made of graphene. The IC also includes metallic structures, such as on-chip inductors and the transistors' sources and drains. The circuit the team built is a broadband radio-frequency mixer, a fundamental component of radios that processes signals by finding the difference between two high-frequency wavelengths." -
What Can't You Say On China's Social Networks?
An anonymous reader writes "China's 450 million Internet users have taken to social networks in a big way. But these social networking sites, founded on the promise of free expression, have an uneasy existence under an authoritarian regime that punishes certain kinds of expression. This article from IEEE Spectrum tells the story of Sina Weibo, the white-hot social networking phenomenon that has taken over China in the past few years. Citizens have used the microblogging service to protest and rebel — but the Chinese government is getting more sophisticated in its handling of these online grumblings. Side note: an English-language version of Sina Weibo is reportedly on the way. Wonder if it will take off in the US?" -
Robots Successfully Invent Their Own Language
An anonymous reader writes "One group of Australian researchers have managed to teach robots to do something that, until now, was the reserve of humans and a few other animals: they've taught them how to invent and use spoken language. The robots, called LingoDroids, are introduced to each other. In order to share information, they need to communicate. Since they don't share a common language, they do the next best thing: they make one up. The LingoDroids invent words to describe areas on their maps, speak the word aloud to the other robot, and then find a way to connect the word and the place, the same way a human would point to themselves and speak their name to someone who doesn't speak their language." -
The Challenges of Tapping Blood Flow For Power
joshuarrrr writes "Researchers in Switzerland have tested small turbines designed to fit inside a human artery, like an implantable hydroelectric generator. The turbines can draw about a milliwatt of power, which would be enough to run a pacemaker. The problem is that the turbines tended to create turbulence, which can cause blood to coagulate into clots. Competing systems avoid the turbulence but have trouble generating enough power." -
Japanese Researchers Test Flying Trains
An anonymous reader writes "As an alternative to maglev trains, Japanese researchers are working on ground-effect vehicles. A ground-effect vehicle takes advantage of fast-moving air and uses some stubby little wings to fly just above the ground, like a maglev without the mag. This is a tricky thing to do, since you have to control the vehicle more like an airplane than a train: you have to deal with pitch, roll, and yaw and not just the throttle. A Japanese research group has built a robotic prototype of a free flying ground-effect vehicle that they're using to test an autonomous three axis stabilization system." -
Who Owns Your Social Identity?
wjousts writes "Who actually owns your username on a website? What rights do you have to use it? An IEEE Spectrum podcast reports: 'What happens if Facebook or Twitter or, say, your blog hosting service, makes you take a different user name? Sound impossible? It's happened. Last week, a software researcher named Danah Boyd woke up to find her entire blog had disappeared, and in fact, had been renamed, because her hosting service had given her blog's name to someone else.' And as important as they are, what protects our accounts are the terms of service agreements. If you read them — and who does? — you'd learn, probably to no surprise, that they protect the provider a lot more than they protect you." -
German Aerospace Robot Plays Catch With Two Balls
HizookRobotics writes "German Aerospace Center (DLR) designed "Rollin' Justin" to fix satellites in space. But robotics work isn't all work and no play ... In the past, DLR engineers had Justin 'dancing like in Pulp Fiction.' More recently, in work to be presented at the International Conference on Robotics and Automation (ICRA) in two weeks, DLR engineers demonstrated whole-body real-time control, allowing Justin to catch two balls at once, or prepare you a cup of coffee." -
Nuclear Risk Expert: Fukushima Fuel May Be Leaking
An anonymous reader writes "Three weeks after the nuclear crisis began at Japan's Fukushima Dai-1 power plant, there's still a real danger of melted nuclear fuel escaping the reactor buildings and releasing a large dose of radiation. So says Theo Theofanous, an engineer who spent 15 years studying the risks of nuclear reactors. Theofanous believes that melted nuclear fuel has already leaked through the reactor vessels and accumulated at the bottoms of the primary containment structures. All attempts to keep the reactor buildings cool may not be enough to prevent the overheated fuel from eating through the concrete floors, he says." -
Android Copy of Danish Man Unveiled
An anonymous reader writes "The Geminoid family, a series of ultra-realistic androids, each a copy of a real person, has a new member: Geminoid DK, a robot clone of a Danish researcher and the most realistic Geminoid yet. The robot has lifelike facial features and movements, blinking, smiling, frowning with incredible realism. The Danish researcher, Henrik Scharfe of Aalborg University, teamed up with Japanese animatronics firm Kokoro and roboticist Hiroshi Ishiguro to create his robot twin, which he plans to use to study human-robot interaction and cultural differences in the perception of robots. This is the first Geminoid that is not based on a Japanese person; it's also the first bearded one." -
Japanese Build Pocket Robot-Cellphone Hybrid
An anonymous reader writes "Japanese researchers unveiled yesterday a pocket-size telepresence robot called Elfoid. The device, which looks like a little ghost, transmits voice and motion over a 3G network to convey a person's 'presence' to a remote location. It's a creation of Hiroshi Ishiguro, a professor at Osaka University who is known for his lifelike teleoperated androids. The Elfoid has a limited range of motion, but its creators are planning to equip it with mini-actuators so it can imitate the movements of the person on the other end of the line. With vaguely formed features, the device is designed to be a surrogate of people of any age or gender." -
The World's First Flexible Organic Microprocessor
An anonymous reader writes "European researchers at Imec recently announced the development of the world's first flexible organic microprocessor at the International Solid-State Circuits Conference in San Francisco CA. 'The 4000-transistor, 8-bit logic circuit has the processing power of only a 1970s-era silicon model, but it has a key advantage—it can bend. The device’s designers say the chip could lead the way to cheaper flexible displays and sensors. Wrapped around pipes, for example, sheets of sensors with these processors could record average water pressure, and wrapped around food and pharmaceuticals, they might indicate that your tuna is rancid or that you forgot to take your pills.'" -
A Car You Can Drive With Your Thoughts
An anonymous reader writes "German researchers have demonstrated a car that can be driven with brain power alone. In the video, a driver wears an EEG head cap, which records brain activity. Software converts the neural signals into steering and acceleration commands, feeding the data into the car's drive-by-wire system. The brain-car interface, which the researchers call the 'BrainDriver,' is far from being commercially viable. But it could one day allow disabled and paralyzed people to gain more mobility. It could also, the researchers say, help people control autonomous vehicles, like a future driverless cab; just by thinking, passengers would tell the cab where to go." -
Harvard Professor Creates Paper Accelerometer
SuperSlacker64 writes "In an age where just about everything starts going digital, it's refreshing to see someone going back to our roots: paper. Well, sort of. Researchers at Harvard have created a cheap, dime-sized, paper-based accelerometer that they believe could be used in various ways, such as inexpensive medical testing. The device works because a carbon bridge stretches and changes resistivity as the device is accelerated." When they say "cheap," they mean it; the cost per device is estimated to be about four cents. -
Japanese Build Robot Toddlers
kgeiger writes "The Japanese birth dearth may be crashing their population and rendering kids a rarity, but never fear! Robotics researchers at Osaka University are building robot babies to learn how people are supposed to interact with young children. For anyone who has raised real kids, cyberkiddies would seem a cheat unless they come with "why? Why? WHY?" and "No!" infinite loops and no OFF switch." -
Supercomputer Advancement Slows?
kgeiger writes "In the Feb. 2011 issue of IEEE Spectrum online, Peter Kogge, an IEEE Fellow and professor of computer science and engineering at the University of Notre Dame, outlines why we won't see exaflops computers soon. To start with, consuming 67 MW (an optimistic estimate) is going to make a lot of heat. He concludes, 'So don't expect to see a supercomputer capable of a quintillion operations per second appear anytime soon. But don't give up hope, either. [...] As long as the problem at hand can be split up into separate parts that can be solved independently, a colossal amount of computing power could be assembled similar to how cloud computing works now. Such a strategy could allow a virtual exaflops supercomputer to emerge. It wouldn't be what DARPA asked for in 2007, but for some tasks, it could serve just fine.'" -
Graphene Won't Replace Silicon In CPUs, Says IBM
arcticstoat writes "IBM has revealed that graphene can't fully replace silicon inside CPUs, as a graphene transistor can't actually be completely switched off. In an interview, Yu-Ming Lin from IBM Research (Nanometer Scale Science and Technology) explained that 'graphene as it is will not replace the role of silicon in the digital computing regime.' Last year, IBM demonstrated a graphene transistor running at 100GHz, while researchers at UCLA produced a graphene transistor with a cut-off frequency of 300GHz, prompting predictions of silicon marching towards its demise, making way for a graphene-based future with 1THz CPUs. However, Lin says, 'there is an important distinction between the graphene transistors that we demonstrated and the transistors used in a CPU. Unlike silicon, graphene does not have an energy gap, and therefore, graphene cannot be "switched off," resulting in a small on/off ratio.' That said, Lin also pointed out that graphene 'may complement silicon in the form of a hybrid circuit to enrich the functionality of computer chips.' He gives the example of RF circuits, which aren't dependent on a large on/off ratio." -
Electronics In Flight — Danger Or Distraction?
another similar writes "IEEE Spectrum has a blog post revisiting the debate on whether electronic devices pose a risk to flight avionics spurred by a NY Post article about Arianna Huffington's refusal to power down her Blackberry during takeoff. The post points out the EU's removal of their own ban on cell phone use in 2007 and the likelihood of significant non-compliance daily in the US — and curiously, planes haven't been falling from the sky at a similar rate. While the potential exists for there to be a problem, it would appear the risk is low. Ever bent the rules? Is an app for landing commercial jets somewhere in our future?" -
Four IT Consultants Charged With $80M NYC Rip-Off
theodp writes "It's I-told-you-so time for Slashdot commenter frnic, who smelled a crime last March after reading that New York City had dropped $722 million on its still-under-development CityTime Attendance System. Nine months later, US Attorney Preet Bharara charged 'four consultants to the New York City Office of Payroll Administration ... for operating a fraudulent scheme that led to the misappropriation of more than $80 million in New York City funds allocated for an information technology project known as "CityTime."' Three of the four consultants were also charged — along with a consultant's wife and mother — with using a network of friends-and-family shell corporations to launder the proceeds of the fraud. Dept. of Investigations Commissioner Rose Gill Hearn called it a shame that 'supposed experts hired and paid well to protect the city's interests were exposed as the fox guarding the hen house.'" -
What Robots Do For Christmas
An anonymous reader writes "Several robotics labs in the US and Europe have decided to make themed Christmas/New Years videos. The subject was left open but in the end it should have had a) something to do with the robotics research in each lab and b) a connection to the holidays. Here's the official announcement on the IEEE Spectrum blog. The videos, including a computer-controlled quadrocopter attempting to play jingle bells on a Yamaha keyboard, are available on the Robotics Podcast YouTube channel. (Disclaimer: I made one of the videos!)" -
How the Free Market Rocked the Grid
sean_nestor sends in a story at IEEE Spectrum that begins: "Most of us take for granted that the lights will work when we flip them on, without worrying too much about the staggeringly complex things needed to make that happen. Thank the engineers who designed and built the power grids for that — but don't thank them too much. Their main goal was reliability; keeping the cost of electricity down was less of a concern. That's in part why so many people in the United States complain about high electricity prices. Some armchair economists (and a quite a few real ones) have long argued that the solution is deregulation. After all, many other US industries have been deregulated — take, for instance, oil, natural gas, or trucking — and greater competition in those sectors swiftly brought prices down. Why not electricity?" -
A Mind Made From Memristors
Csiko writes "Researchers at Boston University's department of cognitive and neural systems are working on an artificial brain implemented with memristors. 'A memristor is a two-terminal device whose resistance changes depending on the amount, direction, and duration of voltage that's applied to it. But here's the really interesting thing about a memristor: Whatever its past state, or resistance, it freezes that state until another voltage is applied to change it. Maintaining that state requires no power.' Also theoretically described, solid state versions of memristors have not been implemented until recently. Now researchers in Boston claim that memristors are the new key technology to implement highly integrated, powerful artificial brains on cheap and widely available hardware within five years."
