US Restarts Hunt For Gravitational Waves With Advanced LIGO
schwit1 writes: The hunt for gravitational waves began again for the Laser Interferometer Gravitational-Wave Observatory (LIGO)-the largest instrument of its kind. The restart follows a five-year-long, US $200-million project to overhaul the experiment's detectors. Many physicists believe the revamped experiment, dubbed Advanced LIGO, will be the first to find direct evidence of gravitational waves: ripples in the fabric of space-time that can be created by, among other things, a pair of neutron stars or black holes orbiting each other. Gravitational waves were first theorized in 1916 by Albert Einstein as a consequence of his general theory of relativity, which celebrates its centennial this year. -
Former NASA Mission Controller James Oberg Lauds 'The Martian'
At IEEE Spectrum, James Oberg gives high praise to the upcoming film The Martian (release date: October 2). Oberg doesn't have much to say about the acting; he concentrates on the physics and plausibility of the plot and the technology portrayed, which beat those of most Hollywood space epics, and notes in particular "There’s no cheating on even highly-technical spaceflight topics, as shown in the treatment of the so-called “Rich Purnell maneuver,” wherein the Hermes slingshots past Earth back to Mars for a desperate pickup attempt. ... The basic strategy of the Rich Purnell maneuver is not fictional—a crippled Japanese Mars probe named Nozomi actually used a similar Earth-flyby scheme to set up a second chance for its own faltering unmanned Mars mission a dozen years ago." Oberg's background gives his appraisal some weight -- he's a former NASA mission controller who specialized in orbital rendezvous maneuvers. He has some quibbles, too, with the way mission personnel are depicted, and notes one excursion into "fantasy mode" near the fim's close, but concludes that it's a fair trade for the overwhelming sense of realism. -
Twitter's Tech Lead On Making Software Engineers More Efficient
Tekla Perry writes: "Engineering productivity is hard to measure," said Peter Seibel, the tech lead of Twitter's engineering effectiveness group. "But we certainly can harm it." Seibel spoke this week at the @Scale conference in San Jose, hosted by Facebook. He says in large companies one third of software engineers shouldn't be working on the company's products, but should be dedicated to making other engineers more effective. "As an industry we know how to scale up software," he said. "We also know how to scale up organizations, to put in management that lets thousands of people work together. But we don't have a handle on how to scale up that intersection between engineering and human organization. And maybe we don't understand the importance of that. We massively underinvest in this kind of work." -
Damaged Spinal Cord "Rewires" Itself With Help of Electrical Stimulation
the_newsbeagle writes: Many prior experiments that tried to restore function after a spinal cord injury have used electrical stimulation to replace the signals from the brain, essentially implanting a replacement nervous system. But a new project instead used electrical stimulation to encourage the natural nervous system to adapt to a severe injury. When researchers repeatedly jolted a rat's damaged spinal cord at the precise moment that it tried to move a paralyzed limb, its nervous system developed new neural pathways that detoured around the site of injury in the spine. Researchers don't think it grew new neurons, but think instead that new connections formed between surviving neurons. -
Researcher Hacks Self-Driving Car Sensors
An anonymous reader writes: Jonathan Petit, security researcher at Security Innovation, has created an electronics kit that costs only $60, which can flood LiDAR sensors on self-driving cars with a laser beam that contains fake data, making them think they have objects in front of them. This forces the self-driving car to slow down and sometimes abruptly stop. Affected cars include all manufacturers that deploy LiDAR sensors. As of now, Google and Apple are affected. According to this article, so may be Toyota's upcoming car. -
Robot Submarine Poisons Sea Stars To Save Coral Reefs
schwit1 writes: A 30-kilogram robotic yellow submarine is keeping sea stars in check with poison. The sea stars periodically have huge population booms, and a square kilometer of reef can be home to 100,000 of them. They'll kill off the reefs if left unchecked, but humans can only kill a couple sea stars per minute. The task is overwhelming but simple and repetitive, and thus ripe for automation. The COTSBot has "a maximum speed of over two meters per second and an endurance of over six hours. Five thrusters give it the capability of briefly hovering in the water column, giving it time to attack crown of thorns sea stars with an integrated poison injection system. It's completely autonomous, down to the identification and targeting of [sea stars] lurking among coral." -
Toyota To Spend $50 Million On Self-Driving Car Tech
An anonymous reader writes: Toyota is the latest automaker to see which way the wind is blowing; they've committed $50 million over the next five years to build research centers for self-driving car technology. They'll be working with both Stanford and MIT, and their immediate goal is to "eliminate traffic casualties." "Research at MIT will focus on 'advanced architectures' that will let cars perceive, understand, and interpret their surroundings. ... The folks at Stanford will concentrate on computer vision and machine learning. ... It will also work on human behavior analysis, both for pedestrians outside the car and the people 'at the wheel.'" Toyota's efforts will be led by Gill Pratt, who ran DARPA's Robotics Challenge. -
Sultan of Sound, Dr. James Flanagan, Passed Away Aged 89
An anonymous reader writes: A pioneer in the field of acoustics, Dr. James L. Flanagan provided "the technical foundation for speech recognition, teleconferencing, MP3 music files, and the more efficient digital transmission of human conversation." The NYTimes covered his recent passing: "His innovations included preserving the sound of a human voice while crunching it digitally, as well as teaching computers to articulate — converting sound waves into digital pulses. He also helped devise a 'force-feedback' tactile glove, similar to today’s video game accessories, that enabled medical students to simulate hands-on examinations when a live patient or cadaver was not available (or to mimic a game of handball). Dr. Flanagan also played a minor role in the drama surrounding the downfall of President Richard M. Nixon." An older (2005) article from IEEE Spectrum titled "Sultan of Sound" provides background on his work and impact. An interview (1997) discussing his WWII service, research at AT&T Bell Labs & Rutgers University is part of the IEEE oral history series. -

Sensor Predicts Which Donated Lungs Will Fail After Transplant
the_newsbeagle writes: A lung transplant can be a life-saving intervention—but sometimes the donated lung stops working inside the recipient's body. This "graft dysfunction" is the leading cause of death for transplant patients in the early days after surgery. While lab tests can look for genetic biomarkers of inflammation and other warning signs in a donated lung, such tests take 6-12 hours in a typical hospital. That's too slow to be useful. Now, researchers at University of Toronto have invented a chip-based biosensor that can do quick on-the-spot genetic tests, providing an assessment of a lung's viability within 30 minutes. -
Implanted Optogenetic Light Switch Lets Scientists Flip Neurons On and Off
the_newsbeagle writes: Optogenetics is a fairly new (and fairly awesome) research tool for neuroscientists: By using light to jolt certain neurons into action, they can study how those neurons function in the mouse brain. But getting the light to those neurons has been difficult. Previous systems have required either fiber optic cables that tether the mouse to a computer, or heavy head-mounted receivers. Now Stanford's Ada Poon has invented a tiny and fully implantable system that wirelessly receives the signal to stimulate, and uses a micro-LED to activate the neurons. The device will let researchers study brain function while mice are running around, interacting socially, etc. -
Mars One CEO Insists, Our Mars Colonization Plan Is Feasible
szotz writes: Mars One CEO Bas Lansdorp has a bizarre definition of the word "plan". Last week he debated two MIT aerospace engineers who were co-authors on a report that said that astronauts would suffocate on Mars if they tried to grow their own food with existing tech. The question on the table: Is the Mars One plan feasible? And the answer seemed to be "it depends on what your definition of a plan is". The stated plan is to send the first humans to Mars for $6 billion by 2027 (twice delayed already). Lansdorp admits they probably won't stick to that schedule or that budget, but that has nothing to do with whether they're going or not. IEEE Spectrum has a write-up of the debate and a link to the MIT team's presentation. It seems the company's looking for $15 million now to fund--you guessed it--more studies. -
Antineutrino Detectors Could Be Key To Monitoring Iran's Nuclear Program
agent elevator writes: Tech that analyzes antineutrinos might be the best way to keep tabs on Iran's nuclear program. The technology, which can tell how much of and what kind of plutonium and uranium are nearby, should be ready to serve as a nuclear safeguard in less than two years, according to IEEE Spectrum. In a simulation of the Arak nuclear plant, which the Iran deal requires be redesigned to make less plutonium, a detector parked outside in a shipping container could do the job. -
Plastic Roads Sound Like a Crazy Idea, Maybe Aren't
schwit1 writes with news that the Dutch city of Rotterdam is looking at partnering with a company called VolkerWessels to test a prototype plastic road for safety and durability. "They envision pulling waste plastic out of the oceans, and then processing it into prefabricated sections of road with integrated utility channels and drainage. The composition and structure of the plastic makes it more durable than traditional asphalt, and VolkerWessels estimates that their plastic roads should last about three times as long as traditional roads." The roads are manufactured at a factory, and then hauled in a mostly finished state to where they'll end up. This could dramatically reduce the time during which drivers are inconvenienced by road construction efforts. -
Paralyzed Man Hits the Streets of NYC In a New Exoskeleton
the_newsbeagle writes: Robert Woo was paralyzed in 2007 when a construction crane dropped a load of steel on him. Yesterday, he put on the newest "exoskeleton," essentially a pair of smart robotic legs, and strolled out into a busy Manhattan sidewalk. He was demoing the ReWalk 6.0, a $77,000 device that he plans to buy for home use. -
Robot Performs Prostate Surgery Inside an MRI
the_newsbeagle writes: Researchers have developed a non-metallic robot with ceramic piezoelectric motors that functions inside an MRI machine, allowing surgeons to perform procedures guided by real-time imaging. It's now being tested in prostate biopsies. Doctors say this system will let them aim their needles more precisely and reduce the number of times they stick them in. The NIH thinks such systems could come in handy for neurosurgery too. Gregory Fischer, a professor of mechanical engineering at WPI whose Automation and Interventional Medicine Robotics Lab led the research says: "You can bring it into any MRI room and have it up and running in an hour. It can locate the target, track the needle, and if it deflects during insertion, it can steer the needle to hit the target. We’re taking baby steps to get the robot into clinical use." -
The Real-Life Dangers of Augmented Reality
Tekla Perry writes: Today's augmented reality devices have yet to go through extensive tests of their impact on their wearers' health and safety. But by looking at existing research involving visual and motor impairments, two Kaiser Permanente researchers find they can draw conclusions about the promise and perils of augmented reality, and point to ways wearable developers can make these devices safer. The researchers write: "Peripheral vision is more important than you might think, because it provides a wealth of information about speed and distance from objects. Central vision, despite the great detail it offers, gives you only a rough estimate of movement toward or away from you, based on changes in size or in the parallax angle between your eyes. But objects moving within your peripheral vision stimulate photoreceptors from the center of the retina to the edge, providing much better information about the speed of motion. Your brain detects objects in your peripheral field and evaluates if and how they (or you) are moving. Interfering with this process can cause you to misjudge relative motion and could cause you to stumble; it might even get you hit by a car one day." -
Triggering a Mouse's Happy Memories With Lasers Gives It the Will To Struggle On
the_newsbeagle writes: With optogenetics, scientists can tag neurons with light-responsive proteins, and then trigger those neurons to "turn on" with the pulse of a light. In the latest application, MIT researchers used light to turn on certain neurons in male mice's hippocampi that were associated with a happy memory (coming into contact with female mice!), and then tested whether that artificially activated memory changed the mice's reactions to a stressful situation (being hung by their tails). Mice who got jolted with the happy memory struggled to get free for longer than the control mice. This tail-suspension test was developed to screen potential antidepressant drugs: If a rodent struggles longer before giving up, it's considered less depressed. -
Computer Modeling Failed During the Ebola Outbreak
the_newsbeagle writes: Last fall, the trajectory of the Ebola outbreak looked downright terrifying: Computational epidemiologists at Virginia Tech predicted 175,000 cases in Liberia by the end of 2014, while the CDC predicted 1.4 million cases in Liberia and Sierra Leone. They were way off. The actual tally as of January 2015: A total of 20,712 cases in Guinea, Liberia, and Sierra Leone combined, and in all three countries, the epidemic was dying down. But the modelers argue that this really wasn't a failure, because their predictions served as worst-case scenarios that mobilized international efforts. -
How Biostamps Can Replace Clunky Biomedical Sensors
An anonymous reader writes: The biostamp--a type of temporary tattoo that feels like skin, yet is laden with electronics--is just about ready for prime time. The technology has entered clinical trials for medical use, and consumer versions, costing just tens of cents, are coming soon. A visit to the University of Illinois researchers developing the technology reveals details about how biostamps work and how they are manufactured. A year from now, don't be surprised if you're wearing one--or two, or three--yourself. -
Tiny Fantastic Voyage Inspired Robots Are Starting To Get Reasonably Mature
szotz writes: No shrinking machine in an underground military lab (as far as we know). And no Raquel Welch. Still there is a growing microrobotics movement underway, looking at ways that tiny, untethered robots might be used to perform medical interventions in the human body. There have been piecemeal reports for years now of various designs, such as microscallops that can swim through the eye and bots that can be pushed around by bacteria flagella. This article in IEEE Spectrum gives a round-up of recent progress and looks at some of the difficulties that arise when you try to make things tiny and still have them retain a modicum (or give them more than a modicum) of function. -
The Artificial Pancreas For Diabetics Is Nearly Here
the_newsbeagle writes: It's the tech that type 1 diabetics have long been waiting for: An implanted "closed-loop" system that monitors a person's blood-sugar level and adjusts injections from an insulin pump. Such a system would liberate diabetics from constant self-monitoring and give parents of diabetic children peace of mind. Thanks to improvements in glucose sensors and control algorithms, the first artificial pancreas systems are now in clinical trials. -
Hacking Your Body Through a Nerve In Your Neck
agent elevator writes: IEEE Spectrum has a feature (part of its Hacking the Human OS issue) on the future of vagus nerve stimulation, a device-based therapy with the potential to treat a ridiculously wide variety of ailments: epilepsy, depression, stroke, tinnitus, heart failure, migraines, asthma, the list goes on. One problem is that, because it required an implant (a bit like a pacemaker), it was never anybody's first-choice therapy. But now there's a non-invasive version, a device you just hold to your neck twice a day for a few minutes. It's being trialed first for migraines and cluster headaches (which sound horrible). If it works, vagus nerve stimulation could compete directly with drug treatments on cost and convenience and it would let doctors find new ways to hack human physiology. -
A Tool For Analyzing H-1B Visa Applications Reveals Tech Salary Secrets
Tekla Perry writes: The golden age of engineers is not over,' says a French software engineer who developed a tool for mining U.S. Department of Labor visa application data, but, he says, salaries appear to be leveling off. Indeed, salary inflation for software engineers and other technical professionals at Google and Facebook has slowed dramatically, according to his database, and Airbnb and Dropbox pay is down a little, though Netflix pay is through the roof. The data also shows that some large companies appear to be playing games with titles to deflate salaries, and Microsoft is finally offering technology professionals comparable salaries to Apple and Google. There's a lot more to be discovered in this interactive database, and researchers are getting ready to mine it. -
Here Comes the Keurig of Everything
Tekla Perry writes: Keurig made a huge business out of single-serving coffee machines. Now, as more complex machinery shrinks in size and cost, many companies are trying to duplicate that success for other types of food and drink. Startups are introducing the Keurig of cocktails, the Keurig of Jell-O shots, and the Keurig of dinner (it makes stir fries, stews, and risottos). The question is: does having a single- or limited-purpose device make really make sense for consumables that aren't coffee? Counter space is not infinite, and most people want more variety out of their lunches, dinners, and nightcaps than they do for their morning pick-me-up. (Also, let's retire this metaphor before we get a Keurig for cats.) -
Are We Entering a "Golden Age of Quantum Computing Research"?
Lashdots writes: Last month, an elite team at IBM Research announced an advance in quantum computing: it had built a four-qubit square lattice of superconducting qubits, roughly one-quarter-inch square, that was capable of detecting and measuring the two types of quantum computing errors (bit-flip and phase-flip). Previously, it was only possible to address one type of quantum error or the other. The next step is to correct quantum errors.
In a blog post, Mark Ritter, who oversees scientists and engineers at IBM's T.J. Watson Research Laboratory, wrote: "I believe we're entering what will come to be seen as the golden age of quantum computing research." His team, he said, is "on the forefront of efforts to create the first true quantum computer." But what would that mean, and what other big next steps are there? -
The World's Most Dangerous Driving Simulator
agent elevator writes: Lawrence Ulrich at IEEE Spectrum has an interview with the maker of a simulator for professional racers. The Motion Pro II from CXC Simulations costs racers $54,000 and up. It conveys amazingly fine sensations, including the feel of the car's tires wearing out or the car lightening as its fuel dwindles. It also has the kick to make you really feel a crash: "If you hit the wall in an Indy Car and don't take your hands off the wheel, you'll break your wrists. Our wheel is a one-to-one replication of that, but we don't turn it up that high. It's the first time we've been able to replicate racing forces so high that it introduces liability questions." -
Centimeter-Resolution GPS For Smartphones, VR, Drones
agent elevator writes: UT Austin engineers have come up with a software fix that corrects for the errors GPS has when using the tiny antennas on smartphones. They demoed it using a VR setup and got 2-cm accuracy. For now it runs on a separate processor from the smartphone, but they say they'll fix that. The demo appears to have been done on a rooftop. VR. Outside. On a roof. Doesn't seem like a good idea, does it? -
Oculus Rift-Based System Brings True Immersion To Telepresence Robots
An anonymous reader writes: University of Pennsylvania researchers have built an Oculus Rift-based telepresence system that attempts to bring true immersion to remotely operated robots. The system, called DORA (Dexterous Observational Roving Automaton), precisely tracks the motion of your head and then duplicates those motions on a mobile robot moving around at a remote location. Video from the robot's cameras is transmitted to the Oculus headset. One of the creators said that while using the system you "feel like you are transported somewhere else in the real world." -
A Light-Powered Retina Implant For the Blind
the_newsbeagle writes: In certain diseases of the retina, people lose function in the photoreceptor cells that respond to light and trigger a message to the brain. So engineers have designed various retina implants that do the job instead, including the Argus II system, which received the first FDA approval for an implanted visual prosthetic in 2013. But the Argus II only produces vision of about 20/1200. A new implant in the pipeline from Stanford University has already achieved 20/250 vision in rats, and is aiming at 20/120, which would be below the legal threshold for blindness. This implant is photovoltaic, so the same infrared light that beams an image of the world into the implanted chip also powers its electronics. -
A Cheap, Ubiquitous Earthquake Warning System
Tekla Perry writes: Earthquake alert systems that give a 10 or 20 second warning of an impending temblor, enabling automatic systems to shut down and people to take cover, are hugely expensive to build and operate. (One estimate is $38.3 milllion for equipment to span California, and another $16.1 million annually to operate.) But a Palo Alto entrepreneur thinks he's got a way to sense earthquakes and provide alerts far more cheaply and with much greater resolution. And he's got money from the National Science Foundation to begin the first test of his system — covering the Bay Area from Santa Cruz to Napa and the cities of Hollister, Coalinga, and Parkfield. He starts that test next month. -
Old Marconi Patent Inspires Tiny New Gigahertz Antenna
agent elevator writes Gehan Amaratunga and a group of engineers in England noted that the Guglielmo Marconi's famous British patent application from 1900 had an interesting and little noticed detail. It depicted a transmitter linked to an antenna connected to a coil, which had one end dangling while the RF signal was fed to the middle of the coil. That detail inspired them to develop a way to reduce the size of a GHz antenna without significant transmission loss by using dielectrics as the radio wave emitting material instead of conductors. -
How Brain Pacemakers Treat Parkinson's Disease
the_newsbeagle writes Pharmaceutical research for neuropsychiatric disorders hasn't produced many breakthroughs lately, which may explain why there's so much excitement around "electroceutical" research. That buzzy new field encompasses deep brain stimulation (DBS), in which an implanted stimulator sends little jolts through the neural tissue. DBS has become an accepted therapy for Parkinson's and other motor disorders, even though researchers haven't really understood how it works. Now, new research may have found the mechanism of action in Parkinson's patients: The stimulation reduces an exaggerated synchronization of neuron activity in the motor cortex. -
Fifty Years of Moore's Law
HughPickens.com writes: IEEE is running a special report on "50 Years of Moore's Law" that considers "the gift that keeps on giving" from different points of view. Chris Mack begins by arguing that nothing about Moore's Law was inevitable. "Instead, it's a testament to hard work, human ingenuity, and the incentives of a free market. Moore's prediction may have started out as a fairly simple observation of a young industry. But over time it became an expectation and self-fulfilling prophecy—an ongoing act of creation by engineers and companies that saw the benefits of Moore's Law and did their best to keep it going, or else risk falling behind the competition."
Andrew "bunnie" Huang argues that Moore's Law is slowing and will someday stop, but the death of Moore's Law will spur innovation. "Someday in the foreseeable future, you will not be able to buy a better computer next year," writes Huang. "Under such a regime, you'll probably want to purchase things that are more nicely made to begin with. The idea of an "heirloom laptop" may sound preposterous today, but someday we may perceive our computers as cherished and useful looms to hand down to our children, much as some people today regard wristwatches or antique furniture."
Vaclav Smil writes about "Moore's Curse" and argues that there is a dark side to the revolution in electronics for it has had the unintended effect of raising expectations for technical progress. "We are assured that rapid progress will soon bring self-driving electric cars, hypersonic airplanes, individually tailored cancer cures, and instant three-dimensional printing of hearts and kidneys. We are even told it will pave the world's transition from fossil fuels to renewable energies," writes Smil. "But the doubling time for transistor density is no guide to technical progress generally. Modern life depends on many processes that improve rather slowly, not least the production of food and energy and the transportation of people and goods."
Finally, Cyrus Mody tackles the question: what kind of thing is Moore's Law? "Moore's Law is a human construct. As with legislation, though, most of us have little and only indirect say in its construction," writes Mody. "Everyone, both the producers and consumers of microelectronics, takes steps needed to maintain Moore's Law, yet everyone's experience is that they are subject to it." -

Vaclav Smil writes about "Moore's Curse" and argues that there is a dark side to the revolution in electronics for it has had the unintended effect of raising expectations for technical progress. "We are assured that rapid progress will soon bring self-driving electric cars, hypersonic airplanes, individually tailored cancer cures, and instant three-dimensional printing of hearts and kidneys. We are even told it will pave the world's transition from fossil fuels to renewable energies," writes Smil. "But the doubling time for transistor density is no guide to technical progress generally. Modern life depends on many processes that improve rather slowly, not least the production of food and energy and the transportation of people and goods."
Finally, Cyrus Mody tackles the question: what kind of thing is Moore's Law? "Moore's Law is a human construct. As with legislation, though, most of us have little and only indirect say in its construction," writes Mody. "Everyone, both the producers and consumers of microelectronics, takes steps needed to maintain Moore's Law, yet everyone's experience is that they are subject to it." -
'Smart Sewer' Project Will Reveal a City's Microbiome
the_newsbeagle writes: Public health officials want to turn streams of sewage into streams of data. A new project in Cambridge, Mass. will equip sewer tunnels with robotic samplers that can routinely collect sewage from 10 different locations. MIT scientists will then analyze the sewage content for early signs of a viral outbreak or a food-borne bacterial illness, and may be able to draw conclusions about specific health trends throughout the city. This Cambridge effort is a proof of concept; the MIT researchers plan to deploy a larger system in Kuwait, where officials are particularly interested in studying obesity and the effectiveness of public health interventions. -
Behind the Scenes At a Quantum Dot Factory
Tekla Perry writes: In a nondescript office complex in Milpitas, Calif., Nanosys is making enough quantum dots to populate 6 million 60-inch television screens annually. "The process goes on in what looks like a microbrewery. In about half a dozen large metal tanks ... Nanosys combines cadmium and selenium and adjusts the temperature, concentration, and catalysts added to force these precursors to combine into stable crystals of cadmium selenide. Then, by readjusting the conditions, the system stops the formation of crystals and triggers the beginning of crystal growth. A computer controls the process according to a programmed “recipe;” staff members monitor the growth of the crystals by shining light on them and measuring the wavelength of the fluorescence; the smallest crystals don’t fluoresce at all, then, as the crystals get larger, the wavelength changes. Nanosys stops the process when the fluoresced light hits the target wavelength, which varies depending on what particular display industry standard that the batch of film is designed to meet." -
First Prototype of a Working Tricorder Unveiled At SXSW
the_newsbeagle writes The $10 million Tricorder X-prize is getting to the "put up or shut up" stage: The 10 finalists must turn in their working devices on June 1st for consumer testing. At SXSW last week, the finalist team Cloud DX showed off its prototype, which includes a wearable collar, a base station, a blood-testing stick, and a scanning wand. From the article: "The XPrize is partnering with the medical center at the University of California, San Diego on that consumer testing, since it requires recruiting more than 400 people with a variety of medical conditions. Grant Campany, director of the Tricorder XPrize, said he’s looking forward to getting those devices into real patients hands. 'This will be a practical demonstration of what the future of medicine will be like,' said Campany at that same SXSW talk, 'so we can scale it up after competition.'" -
Scientists Insert a Synthetic Memory Into the Brain of a Sleeping Mouse
the_newsbeagle writes: Scientists are learning how to insert fake memories into the brain via precise electrical stimulation (abstract). In the latest experiment, they gave sleeping mice a synthetic memory that linked a particular location in a test chamber to a pleasurable sensation. (At least they gave the mice a nice memory.)
The researchers first recorded the electrical signals from the mice's brains while the mice were awake and exploring the test chamber, until the researchers identified patterns of activity associated with a certain location. Then, when the mice slept, the researchers watched for those neural patterns to be replayed, indicating that the mice were consolidating the memory of that location. At that moment, they zapped a reward center of the mice's brains. When the mice awoke and went back into the chamber, they hung around that reward-associated location, presumably expecting a dose of feel-good. -
Would You Need a License To Drive a Self-Driving Car?
agent elevator writes Not as strange a question as it seems, writes Mark Harris at IEEE Spectrum : "Self-driving cars promise a future where you can watch television, sip cocktails, or snooze all the way home. But what happens when something goes wrong? Today's drivers have not been taught how to cope with runaway acceleration, unexpected braking, or a car that wants to steer into a wall." The California DMV is considering something that would be similar to requirements for robocar test-driver training." Hallie Siegel points out this article arguing that we need to be careful about how many rules we make for self-driving cars before they become common. Governments and lawmakers across the world are debating how to best regulate autonomous cars, both for testing, and for operation. Robocar expert Brad Templeton argues that that there is a danger that regulations might be drafted long before the shape of the first commercial deployments of the technology take place. -

Facebook AI Director Discusses Deep Learning, Hype, and the Singularity
An anonymous reader writes In a wide-ranging interview with IEEE Spectrum, Yann LeCun talks about his work at the Facebook AI Research group and the applications and limitations of deep learning and other AI techniques. He also talks about hype, 'cargo cult science', and what he dislikes about the Singularity movement. The discussion also includes brain-inspired processors, supervised vs. unsupervised learning, humanism, morality, and strange airplanes. -
Li-Fi-like System Pushes 100Gbps Within a Small Room
An anonymous reader writes: Oxford University is [building] a system that takes light from the fiber, amplifies it, and beams it across a room to deliver data at more than 100 gigabits per second. ... The trick, of course, is getting the light beam exactly where it needs to go. An optical fiber makes for a target that's only 8 or 9 micrometers in diameter, after all. The team, which also included researchers from University College, London, accomplished this using so-called holographic beam steering at both the transmitter and receiver ends. These use an array of liquid crystals to create a programmable diffraction grating that reflects the light in the desired direction. ... With a 60-degree field of view, the team was able to transmit six different wavelengths, each at 37.4 Gb/s, for an aggregate bandwidth of 224 Gb/s (abstract). With a 36-degree field of view, they managed only three channels, for 112 Gb/s. -

Cosmic Rays To Reveal the Melted Nuclear Fuel In Fukushima's Reactors
the_newsbeagle writes: Muons, produced when cosmic rays collide with molecules in the atmosphere, are streaming through your body as you read this. The particles pass through most matter unimpeded, however they can interact with heavy elements like uranium and plutonium. That's why engineers at Japan's Fukushima Daiichi power plant are using muon detectors to look for the melted nuclear fuel inside the plant's three melted-down reactors. By determining where muons are being diverted from their paths, the detectors create images of the blobs of fuel. That's necessary because nobody knows exactly where the radioactive gloop ended up during the meltdowns. -
Massive Layoff Underway At IBM
Tekla Perry writes: Project Chrome, a massive layoff that IBM is pretending is not a massive layoff, is underway. At more than 100,000 people, it is projected to be the largest mass layoff by any U.S. corporation in at least 20 years. Alliance@IBM, the IBM employees' union, says it has so far collected reports of 5000 jobs eliminated, but those are just numbers of those getting official layoff notices. According to anecdotal reports, IBM appears to be abusing the performance appraisal system to cut additional employees without officially laying them off. -
Brain Implants Get Brainier
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.
