Bird-Shaped Drone Symbolizes New Forms Of Covert Surveillance To Come (mirror.co.uk)
One security writer in Somali recently discovered a downed metal drone that had been carefully disguised as a bird, a reminder that drones will bring powerful new forms of surveillance. Slashdot reader Stephen Sellner also shares an article by the CEO of one unmanned systems company who's predicting that the commercial drone industry will create more than 100,000 new jobs and generate more than $82 billion for the U.S. economy, and suggesting "security of industrial areas (shipyard, storage facility, etc.) can now be augmented by drones to provide a quick eye in the sky."
But it may be inevitable that drones will be used in a variety of unexpected ways. Airbus is also testing the use of drones for quality inspections on their commercial aircraft. In Iowa, a drone helped lead first-responders to a man suffering from a heart attack. And the U.S. wildlife service is planning to drop peanut-butter pellets onto northeastern Montana to deliver vaccines to prairie dogs -- so that they can then in turn be eaten by Montana's population of endangered black-footed ferrets. Any predictions about drone news we'll be seeing in the future? -
MIT's Swarm Chip Architecture Boosts Multi-Core CPUs, Offering Up To 18x Faster Processing (gizmag.com)
An anonymous reader writes from a report via Gizmag: MIT's new Swarm chip could help unleash the power of parallel processing for up to 75-fold speedups, while requiring programmers to write a fraction of the code that is usually necessary for programs to take full advantage of their hardware. Swarm is a 64-core chip developed by Prof. Daniel Sanchez and his team that includes specialized circuitry for both executing and prioritizing tasks in a simple and efficient manner. Neowin reports: "For example, when using multiple cores to process a task, one core might need to access a piece of data that's being used by another core. Developers usually need to write code to avoid these types of conflict, and direct how each part of the task should be processed and split up between the processor's cores. This almost never gets done with normal consumer software, hence the reason why Crysis isn't running better on your new 10-core Intel. Meanwhile, when such optimization does get done, mainly for industrial, scientific and research computers, it takes a lot of effort on the developer's side and efficiency gains may sometimes still be minimal." Swarm is able to take care of all of this, mostly through its hardware architecture and customizable profiles that can be written by developers in a fraction of the time needed for regular multi-core silicon. The 64-core version of Swarm came out on top after MIT researchers tested it out against some highly-optimized parallel processing algorithms, offering three to 18 times faster processing. The most impressive result was when Swarm achieved results 75 times better than the regular chips, because that particular algorithm had failed to be parallelized on classic multi-core processors. There's no indication as to when this technology will be available for consumer devices. -
Highly-Conductive Shark Jelly Could Inspire New Tech (gizmag.com)
An anonymous reader writes: Researchers from UC Santa Cruz, the University of Washington, and the Benaroya Research Institute at Virginia Mason found shark jelly to have the highest proton conductivity ever seen in a biological material. The jelly's conductivity begins to approach that of leading proton-conducting polymers. Tiny organs in the skin of sharks, skates and rays, called the ampullae of Lorenzini, are key to the ability. Scientists believe that the jelly is what has been able to allow these animals to detect weak electric fields produced by their prey, as the organs, which are visible as pores in the skin, are connected to electrosensory cells via long, jelly-filled canals. Marco Rolandi, a co-author on a paper detailing the findings in Science Advances, sees potential use for the "shark jelly" in the development of new or enhanced materials or even the creation of new sensor technology. "The observation of high proton conductivity in the jelly is very exciting," Rolandi said. "We hope that our findings may contribute to future studies of the electrosensing function of the ampullae of Lorenzini and the organ overall, which is itself rather exceptional." -
GoPro Footage Gives You A Rocket's-Eye View Of Spaceflight (gizmag.com)
Eloking quotes a report from Gizmag: Action cameras have been strapped to dogs, chainsaw-wielding drones and everything in between, but there's a new benchmark for homegrown heroes and their action-cam videos courtesy of UP Aerospace. Having strapped a GoPro HERO 4 to the outside of its SpaceLoft-10 sounding rocket, the company launched it into the thermosphere, gathering some footage that's simply out of this world along the way. The footage is incredible and begs the question: how did they fasten the cameras to a rocket traveling at 3,796 mph? You can watch the footage here on YouTube. -
Finger-Tracking Tech Turns Your Arm Into A Touchpad (gizmag.com)
New submitter Keys of Cars quotes a report from Gizmag: Smartwatches may be handy, but their tiny touchscreens can easily be obscured by your fingers as you're using them on the device. As a result, we've seen various attempts to move the control surface. One of the latest, Carnegie Mellon University's SkinTrack system, moves it onto your hand and lower arm. The strap of the smartwatch features multiple electrodes, which detects a ring that is worn on your "control finger" (on your non smartwatch-wearing arm) that emits a high-frequency electrical signal. When your finger, specifically the ring, approaches and/or touches the arm with the watch, the high-frequency electrical signal is propagated through the skin. It will work even if your skin is covered with clothing! The system is reportedly 99% accurate, and can locate touches with a mean error of 7.6mm. SkinTrack was used to control games, scroll through lists, zoom in and out of maps, draw pictures, and operate an onscreen number pad. -
World's Largest Commercial Aircraft Engine Fired Up For The First Time (gizmag.com)
schwit1 quotes a report from Gizmag: With a front fan spreading a full 11 ft (3.35 m), the GE9X is a world record holder and generates thrust in the order of 100,000 lb. To accommodate the aeronautical behemoth, the Peebles facility was recently upgraded with a larger air intake, extra fuel tanks to feed the giant engine, and high temperature gear to deal with the hotter, more efficient design. GE says that the GE9X is currently undergoing its first Full Engine To Test (FETT). This is the next level of the test series, which began in 2011 at the component level, and marks the first test of the complete system, which comes only six months after the engine design was finalized. GE says that this relatively early testing was to ensure that the test data was available as soon as possible for the certification engines, which are scheduled to be installed in GE Aviation's flying test bed for certification of flight testing in 2018. -
DARPA's Latest Grand Challenge Takes On The Radio Spectrum (gizmag.com)
An anonymous reader quotes a report from Gizmag: One of the most hotly contested bits of real estate today is one you can't see. As we move into an increasingly wireless-connected world, staking out a piece of the crowded electromagnetic spectrum becomes more important. DARPA is hoping to help solve this issue with its latest Grand Challenge, which calls for the use of machine-learning technologies to enable devices to share bandwidth. The Spectrum Collaboration Challenge (SC2) is based on the idea that wireless devices would work better if they cooperated with one another rather than fought for bandwidth. Since not all devices are active at all times, the agency says, it should be possible through the use of artificial intelligence machine-learning algorithms to allow them to figure out how to share the spectrum with a minimum of conflict. DARPA announced the competition in front of 8000 engineers on Wednesday at the International Wireless Communications Expo (IWCE) in Las Vegas. SC2 will run from 2017 through 2020 with teams competing to create radios that can collaborate most effectively with other radios. The competition will end with a live event and the prize is $2 million. -
Miniature Fuel Cell To Keep Drones Aloft For Over An Hour (gizmag.com)
Zothecula writes: Drones are being utilized in everything from parcel delivery to search and rescue, but their limited flight times are restricting their ability to travel great distances or stay for extended periods of time in the field. Simply adding more batteries, however, affects flight characteristics and reduces the load the drone can carry. To help solve this problem, researchers at the Pohang University of Science and Technology (Postech) have created a miniature fuel cell they claim not only provides enough energy to keep a drone in the sky for over an hour, but may well find applications in powering everything from smartphones to cars in the not-too-distant future. Developed by Professor Gyeong Man Choi and his Ph.D. student Kun Joong Kim at Postech, the new solid oxide fuel cell is claimed by the researchers to be the first to use porous stainless steel in combination with thin-film electrolyte, all brought together using a technique known as tape casting-lamination-cofiring. Allied with electrodes of low heat capacity, this amalgamation not only results in increased performance, but also in higher long-term durability. The Postech device generates power by converting hydrogen (in this case, "Wet" H2 gas comprising 97 percent H2 and 3 percent H2O mixture) supplied as fuel gas to the anode to create electricity. It does this through the use of a solid oxide material acting as the electrolyte that allows the conduction of negative oxygen ions from the cathode to the anode. These ions diffuse through the solid oxide electrolyte to the anode where they oxidize the fuel. This reaction produces electrons, which then flow through an external circuit to provide power. -
Dutch Researchers Grow Crops In Simulated Lunar and Martian Soil (blastingnews.com)
MarkWhittington writes: When people start living on the moon and Mars on a permanent basis, they are going to need to grow their own crops to produce food to eat. Indeed, in the recent hit movie, "The Martian," Matt Damon's character grew potatoes to survive long enough to be rescued. With that in mind, researchers at Wageningen University in the Netherlands have been trying to grow crops in simulated lunar and Martian soil. The first attempt was not successful. The second, however, proved to have promising results. -
First Bionic Fingertip Implant Delivers Sensational Results (gizmag.com)
Zothecula writes: Dennis Aabo Sorensen may be missing a hand, but he nonetheless recently felt rough and smooth textures using a fingertip on that arm. The fingertip was electronic, and was surgically hard-wired to nerves in his upper arm. He is reportedly the first person in the world to recognize texture using a bionic fingertip connected to electrodes that were surgically implanted above his stump. The device was created by scientists from the Ecole polytechnique federale de Lausanne in Switzerland, and Italy's Scuola Superiore Sant'Anna research institute. While it was wired to Sorensen, a machine moved it across rough and smooth plastic surfaces. Sensors in the fingertip generated electrical signals as they deformed in response to the topography of those surfaces, and transmitted those signals to the nerves in a series of electrical spikes -- this was reportedly an imitation of the "language of the nervous system." He was able to differentiate between the two surfaces with an accuracy of 96 percent. -
Stretchy Squid-Inspired Skin Glows In Different Colors (gizmag.com)
Zothecula writes: Besides having tentacles, squid and octopi are also both known for their color-changing skin. Well, soft-bodied robots may soon also share that attribute, thanks to research being carried out at Cornell University. Led by assistant professor Rob Shepherd, a team of grad students there has developed an electroluminescent rubber "skin" that not only emits light in different colors, but that can also do so while being stretched to more than six times its original length. -
Eavesdropping On 3D Printers Allows Reverse Engineering of Designs (gizmag.com)
Zothecula writes: 3D printers have opened up all kinds of possibilities when it comes to turning digital blueprints into real word objects, but might they also enable new ways to pilfer intellectual property? Amid all that mechanical whirring, these machines emit acoustic signals that give away the motion of the nozzle, new research has found. And by discreetly recording these sounds, scientists say it is possible for sneaky characters to deduce design details and reverse engineer printed objects at a later date. -
Australia Deploys Shark-Spotting Drones To Keep Watch Over Beachgoers (gizmag.com)
Zothecula writes: With tens of thousands of miles of coastline and a recent spike in shark attacks, Australia is exploring some pretty imaginative approaches to ensuring the safety of its beachgoers. Magnetic barriers and shark-tracking phone apps are a few of the tech ideas that have been floated, and the state of New South Wales is now turning to drones to help do the job. It has launched a trial of unmanned shark-spotting aircraft, which will survey the coastline for predators lurking in shallow waters. -
Cheap, High-Performance Green Battery Runs On Rotten Apples (gizmag.com)
Zothecula writes: Researchers at the Karlsruhe Institute of Technology (KIT) have repurposed discarded apples to build cheap and high-performance sodium-ion batteries, making a green technology even greener. The advance could find use in grid storage and, after further development, compete with lithium-ion cells to power portable electronics and low-end electric cars. -
Low-Cost "Paper Skin" Boasts Same Sensory Functions As the Real Thing (gizmag.com)
Zothecula writes: Multipurpose sensors that are both flexible and wearable could one day be used for everything from monitoring the body's vital signs to changing the way we interact with computers. Working toward this goal, researchers in Saudi Arabia have used low-cost everyday items that you probably have laying around your house to develop a paper-based sensor that reacts to the same stimuli as human skin, such as pressure, touch and temperature. -
Wearable Third Arm Gives Drummers Extra Robotic Rhythm (gizmag.com)
Zothecula writes: Thumping out as many drum beats in 60 seconds may get you a podium spot at the annual World's Fastest Drummer competition, but we'll take the full kit virtuoso playing of Cozy Powell, Philthy Animal Taylor or Mitch Mitchell any day of the week. When trying to emulate the fastest or the greatest on your bedroom bin-bashers, though, you'd be forgiven for wishing you had a third arm. Georgia Tech Professor Gil Weinberg and his research team may have the answer to your prayers. They've developed a drumstick-wielding wearable robotic limb that's able to respond to both the music being played and the movements of the player. -
3D-Printed Ear Comes To Life After Implantation In Mice (gizmag.com)
Zothecula writes: 3D printed tissues and organs have shown real potential in addressing shortages of available donor tissue for people in need of transplants, but having them take root and survive after implantation has proven difficult to achieve. In a positive move for the technology, researchers used a newly-developed 3D printer to produce human-scale muscle structures that matured into functional tissue after being implanted into animals. -
Carbon Dioxide From the Air Converted Into Methanol (gizmag.com)
Zothecula writes: The danger posed by rising levels of atmospheric carbon dioxide has seen many schemes proposed to remove a proportion it from the air. Rather than simply capture this greenhouse gas and bury it in the ground, though, many experiments have managed to transform CO2 into useful things like carbon nanofibers or even fuels, such as diesel. Unfortunately, the over-arching problem with many of these conversions is the particularly high operating temperatures that require counterproductive amounts of energy to produce relatively low yields of fuel. Now researchers at the University of Southern California (USC) claim to have devised a way to take CO2 directly from the air and convert it into methanol using much lower temperatures and in a correspondingly simpler way. -
World's Smallest Optical Switch Uses a Single Atom (gizmag.com)
Zothecula writes: The rapid and on-going development of micro-miniature optical electronic devices is helping to usher in a new era of photonic computers and light-based memories that promise super-fast processor speeds and ultra-secure communications. However, as these components are shrunk ever further, fundamental limits to their dimensions are dictated by the wavelength of light itself. Now researchers at ETH Zurich claim to have overcome this limitation by creating both the world's smallest optical switch using a single atom, and accompanying circuitry that appears to break the rules by being smaller than the wavelength of the light that passes through it. -
Wendelstein 7-X Fusion Reactor Produces Its First Flash of Hydrogen Plasma (gizmag.com)
Zothecula writes: Experimentation with Germany's newest fusion reactor is beginning to heat up, to temperatures of around 80 million degrees Celsius, to be precise. Having fired up the Wendelstein 7-X to produce helium plasma late last year, researchers have built on their early success to generate its first hydrogen plasma, an event they say begins the true scientific operation of the world's largest fusion stellarator. -
Graphene Optical Lens a Billionth of a Meter Thick Breaks the Diffraction Limit (gizmag.com)

Weak Electrical Field Found To Carry Information Around the Brain (eurekalert.org)
Zothecula writes: In a development that could lead to improved understanding of memory formation and epilepsy, scientists have discovered a new way information may be traveling throughout the brain. The team has identified slow-moving brainwaves it says could be carried only by the brain's gentle electrical field (abstract), a mechanism previously thought to be incapable of spreading neural signals altogether. "Although the electrical field is of low amplitude, the field excites and activates immediate neighbors, which, in turn, excite and activate immediate neighbors, and so on across the brain at a rate of about 0.1 meter per second." -
Planetary Resources Reveals Out-of-This-World 3D Printing (gizmag.com)
Zothecula writes: If one is going to get into the asteroid mining business, one needs to prove that you can do something with what's brought back. That seems to be the thinking behind Planetary Resources' recent presentation at CES in Las Vegas, where the asteroid mining company unveiled the first object 3D printed using extraterrestrial materials. Made in collaboration with 3D Systems, the nickel-iron sculpture represents a stylized, geometric spacecraft, such as might be used for asteroid mining or prospecting. Planetary Resources says it is representative of what could be printed in a weightless environment. -

Smallest Color Picture Ever Printed Fits Inside a Human Hair (www.ethz.ch)
Zothecula sends news about the tiniest color picture ever printed. Gizmag reports: "Scientists have created a picture that only fleas could truly appreciate. That's because the inkjet-printed image takes up an area no larger than the cross-section of a human hair. The picture of a few clownfish in their sea anemone home measures just 80 micrometers x 115 micrometers for a total area of 0.0092 square mm. Researchers from ETH Zurich University and the startup Scrona have been named the new holders of the Guinness World Record for the world's smallest inkjet color image, which they created using '3D Nanodrip' printing technology created at ETH Zurich." -
Steel Treatment Paves the Way For Radically Lighter, Stronger, Cheaper Cars (gizmag.com)
Zothecula writes: Radically cheaper, quicker and less energy-intensive to produce than regular steel, Flash Bainite is stronger than titanium by weight, and ductile enough to be pressed into shape while cold without thinning or cracking. It's now being tested by three of the world's five largest car manufacturers, who are finding they can produce thinner structural car components that are between 30-50 percent lighter and cheaper than the steel they've been using, while maintaining the same performance is crash tests. Grain of salt: the positive claims here are mostly coming from the company responsible for the process. -
A New Technique For Creating Diamonds Discovered
schwit1 writes: In discovering a new solid state for carbon scientists have also discovered that it is a relatively inexpensive way to produce diamonds. The researchers have found that, depending on the substrates, tiny diamonds will form within the Q-carbon, suggesting that they have actually discovered how diamonds are formed deep below the Earth. The hot high pressure environment there allows Q-carbon to naturally form, and in the process of its solidification diamonds are a byproduct. According to Gizmag: "Professor Jay Narayan of North Carolina State University is the lead author of three papers describing the work that sees Q-carbon join the growing list of carbon solids, a list that includes graphite, graphene, fullerene, amorphous carbon and diamond. He has suggested that the only place Q-carbon might be found in the natural world is in the core of certain planets. The researchers created Q-carbon by starting with a thin plate of sapphire (other substrates, such as glass or a plastic polymer, will also work). Using a high-power laser beam, they coated the sapphire with amorphous carbon, a carbon form with no defined crystalline structure. They then hit the carbon with the laser again, raising its temperature to about 4,000 Kelvin, and then rapidly cooled, or quenched, the melted carbon. This stage of quenching is where 'Q' in Q-carbon comes from." -
Graphene Shows Promise For Super Strong Dental Fillings (elsevier.com)
Zothecula writes: A team of researchers from four institutions located in Romania and St. Kitts have worked together to determine whether graphene could be used to create more durable dental materials. They worked to test how toxic (abstract) different forms of the material were to teeth, with promising results. "Typical metal fillings can corrode and composite fillings are not very strong; Graphene, on the other hand, is 200 times stronger than steel and doesn't corrode, making it a prime new candidate for dental fillings." -
Airbus Patent Shows Modular, Removable Aircraft Cabins (gizmag.com)

Gizmag reports: "A team of researchers in France has taken a major step towards powering our devices with rechargeable batteries based on an element that is far more abundant and cheaper than lithium. For the first time ever, a battery has been developed using sodium ions in the industry standard "18650" format used in laptop batteries, LED flashlights and the Tesla Model S, among other products." -
Scientists Turn Gold Into Foam That's Nearly As Light As Air (www.ethz.ch)
Zothecula writes: Along with its use in jewelry, gold also has numerous applications in fields such as electronics and scientific research. It's a handy material, but – of course – it's also expensive. That's why researchers at ETH Zurich have developed a new way of making a small amount of gold go a long way. They've created a gold foam that looks much like solid gold, but is actually 98 parts air and two parts solid material (abstract). As an added bonus, the aerogel-type foam can also be made in non-gold colors such as dark red. -
Scientists Produce Graphene 100 Times Cheaper Than Ever Before (gizmag.com)
Zothecula writes that researchers at the University of Glasgow have found a way to produce large sheets of graphene 100 times more cheaply than previous methods. Gizmag reports: "Since first being synthesized by Andre Geim and Kostya Novoselov at the University of Manchester in 2004, there has been an extensive effort to exploit the extraordinary properties of graphene. However the cost of graphene in comparison to more traditional electronic materials has meant that its uptake in electronic manufacturing has been slow. Now researchers at the University of Glasgow have discovered a way to create large sheets of graphene using the same type of cheap copper used to manufacture lithium-ion batteries." -
First Images Ever Taken of a Planet Being Formed, 450 Light-Years From Earth (sydney.edu.au)
Zothecula writes: Of the many new exoplanets discovered over the past two decades, all have been identified as established, older planets – none have been acknowledged as newly-forming protoplanets. Now scientists working at the Keck observatory have spied just such a planet in the constellation of Taurus, some 450 light-years from Earth (abstract), that is only just beginning its life, collecting matter and spinning into a brand new world. -
First Liquid-Cooling Laser Could Advance Biological Research (washington.edu)
Zothecula writes: In a world where lasers are sci-fi's weapon of choice for melting away an enemy spaceship, researchers at the University of Washington have swum against the current and produced the first laser capable of cooling liquids. " They demonstrated that the laser could refrigerate saline solution and cell culture media that are commonly used in genetic and molecular research. To achieve the breakthrough, the UW team used a material commonly found in commercial lasers but essentially ran the laser phenomenon in reverse. They illuminated a single microscopic crystal suspended in water with infrared laser light to excite a unique kind of glow that has slightly more energy than that amount of light absorbed. This higher-energy glow carries heat away from both the crystal and the water surrounding it." The technology could be especially useful for slowing down single cells and allowing scientists to study biological processes as they happen. -
World's First "Porous Liquid" Could Be Used For CO2 Sequestration (gizmag.com)
Zothecula sends word that scientists have developed the world's first "porous" liquid that can potentially be used to capture carbon emissions. Gizmag reports: "The Italians have a colorful expression – to make a hole in water – to describe an effort with no hope of succeeding. Researchers at Queen's University Belfast (QUB), however, have seemingly managed the impossible, creating a class of liquids that feature permanent holes at the molecular level. The properties of the new materials are still largely unknown, but what has been gleaned so far suggests they could be used for more convenient carbon capturing or as a molecular sieve to quickly separate different gases." -

Terahertz Radiation To Enable Portable Particle Accelerators (www.desy.de)
Zothecula writes with this Gizmag story about an interdisciplinary team of researchers who have built the first prototype of a miniature particle accelerator that uses terahertz radiation. "Researchers at MIT in the US and DESY (Deutsches Elektronen-Synchrotron) in Germany have developed a technology that could shrink particle accelerators by a factor of 100 or more. The basic building block of the accelerator uses high-frequency electromagnetic waves and is just 1.5 cm (0.6 in) long and 1 mm (0.04 in) thick, with this drastic size reduction potentially benefitting the fields of medicine, materials science and particle physics, among others." -
DARPA's ICARUS Program To Develop Self-Destructing Air Delivery Vehicles (darpa.mil)
Zothecula contributes this excerpt from Gizmag that illustrates the latest chapter in the long history of denying equipment of military technology to the makers' adversaries: Two years ago, DARPA started developing self-destructing electronics as a way to prevent advanced military gear falling into the wrong hands. Now the agency is expanding on the idea with its Inbound, Controlled, Air-Releasable, Unrecoverable Systems (ICARUS) program, which is tasked with developing small, unmanned, single-use, unpowered air vehicles that can can be dropped from an aircraft to deliver supplies to isolated locations in the event of disasters, then evaporate into thin air once their job is done. -
Paralyzed Man Uses Own Brainwaves To Walk Again -- No Exoskeleton Required
Zothecula writes: A man suffering complete paralysis in both legs has regained the ability to walk again using electrical signals generated by his own brain. Unlike similar efforts that have seen paralyzed subjects walk again by using their own brainwaves to manually control robotic limbs, the researchers say this is the first time a person with complete paralysis in both legs due to spinal cord injury was able to walk again under their own power and demonstrates the potential for noninvasive therapies to restore control over paralyzed limbs. -
AeroVelo Breaks Human-powered Land Speed Record
yyzmcleod sends news that AeroVelo, a Canadian team of engineers and students, has built a bike that successfully broke the human-powered land speed record. (This is the same group that built a human-powered helicopter in 2013.) The team's Eta recumbent speed bike managed a speed of 85.7mph (137.9km/h). The previous record was 83.1 mph. -
New Tech Puts the Brakes On Bullets Fired From Police Sidearms
Zothecula writes: Police officers are trained to shoot for the center of mass, not necessarily to kill, but to stop – although the end result can often be one and the same. "The Alternative" is designed to give officers a less lethal option in the form of a clip-on "air bag" for semiautomatic pistols that reduces the velocity of a standard round to make it less lethal. At the front of the bright orange carrier is a hollow sphere made of a proprietary alloy that catches the bullet and firmly embeds it as it leaves the barrel. The ball and bullet fuse, slowing the round by 80 percent. At this speed, the ball-encased round is less likely to penetrate flesh, but it will transfer enough kinetic energy across a wide surface to knock a suspect down with less chance of a lethal outcome. -
Completely Paralyzed Man Walks In Robotic Exoskeleton
Zothecula writes: Working with a team of UCLA scientists, a man with protracted and complete paralysis has recovered sufficient voluntary control to take charge of a bionic exoskeleton and take many thousands of steps. Using a non-invasive spinal stimulation system that requires no surgery, this is claimed (abstract) to be the first time that a person with such a comprehensive disability has been able to actively and voluntarily walk with such a device. -
Shape-Shifting Navigation Device Points You In the Right Direction
Zothecula writes: Developed by Yale engineer Adam Spiers, the Animotus is a wirelessly-connected, 3D printed cube that changes shape to help direct you like a haptic compass. Gizmag reports: " Spiers designed Animotus when he was involved in a performance of Flatland, an interactive play based on Edwin A. Abbott's 1884 story of a two-dimensional world. As part of the stage production, audience members – both sighted and visually impaired – were kept in complete darkness and walked four at a time though the performance space with narrative voice overs and sound effects telling the story as they wandered through. In their hands, each participant held an Animotus that guided them by changing shape to point them in the right direction. With a multi-sectioned body created in a 3D printer, that Animotus alters shape in response to wireless instructions to indicate the user’s position in their environment. To do this, the top half of the cube twists around to point users toward their next destination and then slides forward to give a relative indication of the distance to get there. As a result, rather than having to look at a device, such as the screen of a smartphone, the user was able to determine their path by touch." -
Mice Brainpower Boosted With Alteration of a Single Gene
Zothecula writes: By altering a single gene to inhibit the activity of an enzyme called phosphodiesterase (PDE4B), researchers have given mice the opportunity to see what an increase in intelligence is like. "They tended to learn faster, remember events longer and solve complex exercises better than ordinary mice. For example, the “brainy mice” showed a better ability than ordinary mice to recognize another mouse that they had been introduced to the day before (abstract). They were also quicker at learning the location of a hidden escape platform in a test called the Morris water maze. However, the PDE4B-inhibited mice also showed less recall of a fearful event after several days than ordinary mice." While many people would welcome such a treatment, the scientists say their research could lead to new treatments for those with cognitive disorders and age-related cognitive decline. -
Breathalyzer Bike Lock Stops Drunken Cyclists In Their Tracks
Zothecula writes: Driving while drunk is a bad idea even on a bike. Slowed reflexes and decreased awareness of the world around them can make a drunk cyclist a danger on the road. Working in much the same way as breath-test locks for your car, the Alcoho-Lock aims to prevent cyclists from hopping in the seat when they've had one too many. The device even comes with a smartphone app that connects with the lock over Bluetooth and lets a loved one know that you are trying to bike drunk.
