Microbots Deliver Medical Payload In Living Creature For the First Time
Zothecula writes: Researchers working at the University of California, San Diego have claimed a world first in proving that artificial, microscopic machines can travel inside a living creature and deliver their medicinal load without any detrimental effects. Using micro-motor powered robots propelled by gas bubbles made from a reaction with the contents of the stomach in which they were deposited, these miniature machines have been successfully deployed in the body of a live mouse. -
Exoplanet Hunting NGTS Telescope Array Achieves First Light
Zothecula writes The Next-Generation Transit Survey (NGTS) array, built by a UK, German and Swiss consortium, has achieved first light at the Paranal Observatory in Chile. The installation is designed to search for exoplanets between two and eight times the size of Earth, studying them as they pass in front of their parent star. -
Project Ryptide Drone Flies Life-Rings To Distressed Swimmers
Zothecula writes The speed that drones can be deployed makes them ideal for delivering items when time is of the essence. The Ambulance Drone and Defikopter, for example, are used for transporting defibrillators to those in need. Now, Project Ryptide plans to use drones to deliver life-rings to swimmers in distress. From the article: "The project, which is at pre-production prototype stage, was conceived by Bill Piedra, a part-time teacher at the King Low Heywood Thomas (KLHT) school in Stamford, Connecticut. Piedra began working on the design in January 2014 and then began developing it further with students at KLHT in September 2014. 'Ryptide was designed so that anyone can be a lifeguard,' Piedra tells Gizmag. 'We had the casual user in mind when we designed the basic model; someone that might take their drone to the beach, boating, a lake, or even ice skating. It could be useful in the case of someone falling through the ice while skating, for example.'" -
Super-Sensitive Motion Sensor Could Be Used To Hunt For Extraterrestrial Life
Zothecula writes: People often state that certain planets are too hot, cold or toxic to support life. The catch, however, is that those people are really just talking about life as we know it here on Earth. By that same token, when rovers exploring other planets seek out chemical signatures associated with life forms, they're only able to identify chemicals that we know to look for. That's why Swiss scientists from the EPFL research center have created a device that identifies microscopic life based on nanoscale movements instead of chemistry (abstract). -
BU Students Working On a Cheaper, Gentler Suborbital Rocket
Zothecula writes The International Space Station may get all the glory, but suborbital rocket flights still play a vital part in space research. The problem is that even though such flights only go to the edge of space, they are expensive, few in number, and put massive stresses on experiments. Partly funded by a Kickstarter campaign, students at Boston University are developing an inexpensive suborbital rocket for educational purposes that uses new engine designs to create a cheaper, reusable suborbital rocket that's easier on the payload. -
ESA Carries Out Asteroid Impact Drill
Zothecula writes: If there were any dinosaurs around, they could tell you that an asteroid impact can ruin your whole day. But if we did learn that one was actually going to strike the Earth in a month, what would the authorities do? To find out, the European Space Agency held its first ever mock asteroid drill to work on solutions and identify problems in how to handle such a catastrophe. -
"Infrared Curtain" Brings Touchscreen Technology To Cheap Cars
An anonymous reader writes with news about an affordable way to integrate touch screen technology in any car. "Although touchscreen controls are appearing in the dashboards of an increasing number of vehicles, they're still not something that one generally associates with economy cars. That may be about to change, however, as Continental has announced an "infrared curtain" system that could allow for inexpensive multi-touch functionality in any automobile. The infrared curtain consists of a square frame with a series of LEDs along two adjacent sides, and a series of photodiodes along the other two. Each LED emits a beam of infrared light, which is picked up and converted into an electrical signal by the photodiode located in the corresponding spot on the opposite side of the frame." -
Startup Helps You Build Your Very Own Picosatellite On a Budget
Zothecula writes A Glasgow-based startup is reducing the cost of access to space by offering "satellite kits" that make it easier for space enthusiasts, high schools and universities alike to build a small but functional satellite for as little as US$6,000 and then, thanks to its very small size, to launch for significantly less than the popular CubeSats. -
"Fat-Burning Pill" Inches Closer To Reality
Zothecula writes with news that a fat burning pill may be on the horizon. "Researchers at Harvard University say they have identified two chemical compounds that could replace "bad" fat cells in the human body with healthy fat-burning cells, in what may be the first step toward the development of an effective medical treatment – which could even take the form of a pill – to help control weight gain. Not all fat is created equal. While white fat cells store energy as lipids and contribute to obesity, heart disease and type 2 diabetes, the less common brown fat cells pack energy in iron-rich mitochondria, have been shown to lower triglyceride levels and insulin resistance in mice, and appear to be correlated with lower body weight in humans. Brown fat makes up about five percent of the body mass of healthy newborns, helping them keep warm, and is still present in lower quantities in our neck and shoulders as adults, where it helps burn the white fat cells." -
Photoswitch Therapy Restores Vision To Blind Lab Animals
Zothecula writes: A new genetic therapy that helped blind mice and dogs respond to light stimulus could restore sight to people who suffer from diseases such as retinitis pigmentosa (a gradual loss of vision from periphery inwards). The therapy uses chemicals known as photoswitches, which change shape when hit with light, to open the channels that activate retinal cells. Treated mice can distinguish between steady and flashing light (abstract), while dogs with late-stage retinal degeneration also regain some sensitivity to light. -
Berkeley Lab Builds World Record Tabletop-Size Particle Accelerator
Zothecula writes Taking careful aim with a quadrillion watt laser, researchers at the US Department of Energy's Lawrence Berkeley National Lab claim to have managed to speed up subatomic particles to the highest energies ever recorded for a compact accelerator. By blasting plasma in their tabletop-size laser-plasma accelerator, the scientists assert that they have produced acceleration energy of around of 4.25 giga-electron volts. Acceleration of this magnitude over the short distances involved correlates to an energy rise 1,000 times greater than that of a traditional – and very much larger – particle accelerator. -
Nanotube Film Could Replace Defective Retinas
Zothecula writes: A promising new study (abstract) suggests that a wireless, light-sensitive, and flexible film could potentially form part of a prosthetic device to replace damaged or defective retinas. The film both absorbs light and stimulates neurons without being connected to any wires or external power sources, setting it apart from silicon-based devices used for the same purpose. It has so far been tested only on light-insensitive retinas from embryonic chicks, but the researchers hope to see the pioneering work soon reach real-world human application. -
Practical Magnetic Levitating Transmission Gear System Loses Its Teeth
Zothecula writes: A new transmission device that uses magnetic levitation to almost completely eliminate friction and wear has been developed as part of the MAGDRIVE research project, a collaboration of seven European nations. The creation of the unit entailed the development of a magnetic gear reducer and corresponding frictionless magnetic axles. Aimed primarily for use in spacecraft due to its extended mechanical life, the system is also adaptable for use in automobiles, railways, and aircraft. -
Swiss Scientists Discover DNA Remains Active After Space Journey and Re-entry
Zothecula writes: It may sound like the first chapter of a Quatermass thriller, but scientists from the University of Zurich have discovered that DNA can survive not only a flight through space, but also re-entry into the Earth's atmosphere and still remain active. The findings are based on suborbital rocket flights and could have considerable impact on questions about the origins of life on Earth and the problems of terrestrial space probes contaminating other planets. -
Uber's Android App Caught Reporting Data Back Without Permission
Zothecula writes Security researcher GironSec has pulled Uber's Android app apart and discovered that it's sending a huge amount of personal data back to base – including your call logs, what apps you've got installed, whether your phone is vulnerable to certain malware, whether your phone is rooted, and your SMS and MMS logs, which it explicitly doesn't have permission to do. It's the latest in a series of big-time missteps for a company whose core business model is, frankly, illegal in most of its markets as well. -
WaveNET – the Floating, Flexible Wave Energy Generator
Zothecula writes: Scotland's Albatern is putting a new, modular spin on renewable energy generation. WaveNET is a scalable array of floating "Squid" generator units that harvest wave energy as their buoyant arms rise and fall with the motion of the waves. Each Squid can link up to as many as three others, effectively creating a large, floating grid that's flexible in every direction. The bigger this grid gets, the more efficient it becomes at harvesting energy, and the more different wave movements it can extract energy from. Albatern's 10-year target is to have 1.25 kilometer-long floating energy farms pumping out as much as 100 megawatts by 2024. -
NASA To Deploy Four Spacecraft To Study Magnetic Reconnection
Zothecula writes: NASA has released a video depicting the initial deployment of an undertaking designed to study a phenomenon known as magnetic reconnection. "Reconnection happens when magnetic field lines explosively realign and release massive bursts of energy, while hurling particles out at nearly the speed of light in all directions. Magnetic reconnection powers eruptions on the sun and – closer to home – it triggers the flow of material and energy from interplanetary space into near-Earth space." The launch of the Magnetospheric Multiscale (MMS) mission will see four identical spacecraft deployed from a single Atlas V rocket, set to lift off from cape Canaveral, Florida, no earlier than March next year. -
Nuclear Weapons Create Their Own Security Codes With Radiation
Zothecula writes "Nuclear weapons are a paradox. No one in their right mind wants to use one, but if they're to act as a deterrent, they need to be accessible. The trick is to make sure that access is only available to those with the proper authority. To prevent a real life General Jack D Ripper from starting World War III, Livermore National Laboratory's (LLNL) Defense Technologies Division is developing a system that uses a nuclear weapon's own radiation to protect itself from tampering. -
People Trained To Experience an Overlap In Senses Also Receive IQ Boost
Zothecula writes Tasting lemons when they see a number seven, regarding a certain letter as being yellow in color. Not a great deal is known about why some people experience an overlapping of the senses, a phenomena known as synesthesia. But a new study conducted at the University of Sussex has suggested that specific training of the mind can induce the effects of the condition. The study even suggests that such training can boost a person's IQ. -
Martin Jetpack Closer To Takeoff In First Responder Applications
Zothecula writes Last year's redesign of the long-awaited Martin Jetpack was accompanied by plans to begin commercial sales in 2014, starting with emergency response services and individual sales to follow thereafter. The release date for the first responder Jetpack has since been revised to 2016, a prediction bolstered by the fresh announcement of a partnership between Martin Aircraft Company and US company Avwatch to develop air-based, first responder solutions for the US Department of Homeland Security and Department of Defense. -
Boeing Readies For First Ever Conjoined Satellite Launch
Zothecula writes Boeing has successfully joined two of its 702SP satellites in a stacked configuration in preparation for a launch scheduled for early 2015. Aside from being the first involving conjoined satellites, the launch will also put the first satellites to enter service boasting an all-electric propulsion system into orbit. "Designed by Boeing Network & Space Systems and its defense and security advanced prototyping arm, Phantom Works, the 702SP (small platform) satellites are an evolution of the company's 702 satellite. Operating in the low- to mid-power ranges of 3 to 9 kW, instead of chemical propulsion, the satellites boast an all-electric propulsion system that Boeing says minimizes the mass of the spacecraft and maximizes payload capacity." -
NASA Tests Aircraft With Shape Shifting Wings
Zothecula writes In January, we first heard about FlexFoil; a variable geometry airfoil system that seamlessly integrates into the trailing edge of the wing. During the year the system has made the leap from the test bench to the sky, with NASA conducting tests of the FlexFoil on a modified Gulfstream III business jet. -
Human Clinical Trials To Begin On Drug That Reverses Diabetes In Animal Models
Zothecula writes: A study at the University of Alabama at Birmingham has shown that verapamil, a drug widely used to treat high blood pressure, irregular heartbeat and migraine headaches, is able to completely reverse diabetes in animal models. The UAB team will now move onto clinical trials to see if the same results are repeated in humans. -
Low-Cost 3D-Printed Prosthetic Hand To Be Tested On Amputees In Ecuador
Zothecula writes A PhD candidate and six undergraduate students at the University of Illinois at Urbana-Champaign (UCIC) have created a low-cost, programmable, 3D-printed prosthetic hand that may soon change the lives of amputees in Ecuador. The hand costs just $270 to manufacture, making it a small fraction of the cost of a typical prosthetic of this type. -
Prosthetic Hand Capable of Delivering Texture Sensations
Zothecula writes: A new prosthetic system allows amputees to feel familiar sensations and also, somewhat unexpectedly, reduces their phantom pain. Researchers at Case Western Reserve University and the Louis Stokes Cleveland Veterans Affairs Medical Center developed the system to reactivate areas of the brain that produce the sense of touch, but recipients of prosthetic hands reported their phantom pain subsiding almost completely after being hooked up to the system. -
Breakthrough In LED Construction Increases Efficiency By 57 Percent
Zothecula writes: With LEDs being the preferred long-lasting, low-energy method for replacing less efficient forms of lighting, their uptake has dramatically increased over the past few years. However, despite their luminous outputs having increased steadily over that time, they still fall behind more conventional forms of lighting in terms of brightness. Researchers at Princeton University claim to have come up with a way to change all that by using nanotechnology to increase the output of organic LEDs by 57 percent. -
Facebook To Start Testing Internet-Beaming Drones In 2015
Zothecula writes There was an understandable amount of skepticism when Amazon announced its grand plans for delivery drones last year. But if the last twelve months are any indication, Jeff Bezos and his fellow tech heavyweights are actually kinda serious about the potential of unmanned aerial vehicles. Speaking at the Social Good Summit in New York on Monday, engineering director at Facebook Connectivity Lab, Yael Maguire, has further detailed the company's vision of internet-carrying drones, with plans to begin testing in 2015. -
SkyOrbiter UAVs Could Fly For Years and Provide Global Internet Access
Zothecula writes The internet has become a critical means of communication during humanitarian crises and a crucial everyday tool for people around the world. Now, a Portuguese company wants to make sure everyone has access to it. Quarkson plans to use SkyOrbiter unmanned aerial vehicles (UAVs) to transmit internet access "to every corner of the world." -
Intel Putting 3D Scanners In Consumer Tablets Next Year, Phones To Follow
Zothecula writes: Intel has been working on a 3D scanner small enough to fit in the bezel of even the thinnest tablets. The company aims to have the technology in tablets from 2015, with CEO Brian Krzanich telling the crowd at MakerCon in New York on Thursday that he hopes to put the technology in phones as well. -
Hidden Archeology of Stonehenge Revealed In New Geophysical Map
An anonymous reader writes Utilizing a comprehensive array of remote sensing technology and non-invasive geophysical survey equipment, researchers working on the site of Stonehenge in Wiltshire, England have revealed hundreds of previously unknown features buried deep beneath the ground as part of the Stonehenge Hidden Landscapes Project. The finds include images of dwellings from the Bronze and Iron Ages as well as details of buried Roman settlements never before seen." -
Scientists Regenerate Rat Muscle Tissue
Zothecula writes Muscle lost through traumatic injury, congenital defect, or tumor ablation may soon be regenerated from within. A team of researchers at Wake Forest Baptist Medical Center has shown how stem cells in the body of mice and rats can be mobilized to form new muscle in damaged regions. "Working to leverage the body’s own regenerative properties, we designed a muscle-specific scaffolding system that can actively participate in functional tissue regeneration," explains Sang Jin Lee, senior author on the study. This scaffold was implanted in the rats' tibialis anterior muscle (which is found below the knee), serving as a kind of home for the muscle progenitor cells to grow and develop. -
Dirty Diapers Used To Grow Mushrooms
Zothecula writes While their contents might be considered an environmental hazard by many, disposable diapers themselves pose a more significant problem for the environment. According to the EPA, the average baby will work their way through 8,000 of them before they end up in landfill where they'll take centuries to break down. In an effort to reduce the problem, scientists at Mexico's Autonomous Metropolitan University, Azcapotzalco (UAM-A), have turned used diapers to the task of growing mushrooms. -
Hitachi Developing Reactor That Burns Nuclear Waste
Zothecula writes The problem with nuclear waste is that it needs to be stored for many thousands of years before it's safe, which is a tricky commitment for even the most stable civilization. To make this situation a bit more manageable, Hitachi, in partnership with MIT, the University of Michigan, and the University of California, Berkeley, is working on new reactor designs that use transuranic nuclear waste for fuel; leaving behind only short-lived radioactive elements. -
For $1.5M, DeepFlight Dragon Is an "Aircraft for the Water"
Zothecula writes No one with red blood in their veins buys a sports car and hands the keys to a chauffeur, so one of the barriers to truly personal submarining has long been the need for a trained pilot, not to mention the massive logistics involved in transporting, garaging and launching the underwater craft ... until now. Pioneering underwater aviation company DeepFlight is set to show an entirely new type of personal submarine at the 2014 Monaco Yacht Show next week, launching the personal submarine era with a submersible that's reportedly so easy to pilot that it's likely to create a new niche in the tourism and rental market. -
Scientists Developing Remote-Control Cyborg Moths
Zothecula writes We've been hearing a lot about the development of tiny flying sensor-equipped robots, that could be sent into areas such as disaster sites to seek out survivors or survey the damage. However, why go to the trouble of designing those robots from scratch, when there are already ready-made insects that are about the right size? That's the thinking behind research being conducted at North Carolina State University, which is aimed at converting moths into "biobots". -
Software Combines Thousands of Online Images Into One That Represents Them All
Zothecula writes If you're trying to find out what the common features of tabby cats are, a Google image search will likely yield more results than you'd ever have the time or inclination to look over. New software created at the University of California, Berkeley, however, is designed to make such quests considerably easier. Known as AverageExplorer, it searches out thousands of images of a given subject, then amalgamates them into one composite "average" image. -
Involuntary Eye Movement May Provide Definitive Diagnosis of ADHD
Zothecula writes: If a child who's simply very active is mistakenly diagnosed with Attention Deficit Hyperactivity Disorder (ADHD), he can end up on pharmaceuticals such as Ritalin unnecessarily. The problem is, it can be quite difficult to determine if someone actually has ADHD, and misdiagnoses are common. Now, however, researchers from Tel Aviv University have announced that analyzing a patient's eye movements may be the key. "The researchers found a direct correlation between ADHD and the inability to suppress eye movement in the anticipation of visual stimuli. The research also reflected improved performance by participants taking methylphenidate, which normalized the suppression of involuntary eye movements to the average level of the control group." -
Experimental Drug Compound Found To Reverse Effects of Alzheimer's In Mice
Zothecula (1870348) writes "While there has been progress made in the fight against Alzheimer's, our understanding of the dispiriting disease remains somewhat limited, with a definitive cure yet to be found. The latest development comes at the hands of researchers from Yale's School of Medicine, who have discovered a new drug compound shown to reverse the effects of Alzheimer's in mice." -
Perlan II Project Aims To Fly a Glider To the Edge of Space
Zothecula writes: In an ambitious attempt to break every wing-borne sustained flight height record for a manned aircraft, the Perlan ll project intends to construct and fly a glider higher than any sailplane has gone before. Riding on the colossal stratospheric air waves generated over mountains, the team plans to fly their craft to more than 90,000 ft (27,000 m), which will shatter their own existing glider altitude record of 50,671 ft (15,400 m) set by Perlan l in 2008. -
Quiet Cooling With a Copper Foam Heatsink
Zothecula writes: The Silent Power PC is claimed to be the first high-end PC able to ditch noisy electric fans in favor of fully passive cooling. In place of a conventional fan, the unit uses an open-air metal foam heatsink that boasts an enormous surface area thanks to the open-weave copper filaments of which it's composed. The Silent Power creators claim that the circulation of air through the foam is so efficient in dissipating heat that the exterior surface temperature never rises above 50 C (122 F) in normal use. -
Gene Therapy Converts Heart Cells Into "Biological Pacemakers"
Zothecula (1870348) writes Pacemakers serve an invaluable purpose, by electrically stimulating a recipient's heart in order to keep it beating at a steady rate. The implantation of a pacemaker is a major surgical procedure, however, plus its presence in the body can lead to complications such as infections. Now, for the first time, scientists have instead injected genes into the defective hearts of pigs, converting unspecialized heart cells into "biological pacemakers." Research Paper (abstract, full text paywalled). -
US Marines Demonstrate Ultra Heavy-Lift Amphibious Connector Prototype
Zothecula writes In a recent demonstration carried out during RIMPAC 2014, the US Marines displayed and tested a fully-functional, half-scale prototype of its new amphibious transport vehicle. The proposed full-size version of the Ultra Heavy-Lift Amphibious Connecter (UHAC) is designed to power across the water with a payload of nearly 200 tons at up to 20 knots and be capable of driving up on to the shore and over the top of obstructions up to 10ft high. -
Nano-Pixels Hold Potential For Screens Far Denser Than Today's Best
Zothecula (1870348) writes "The Retina displays featured on Apple's iPhone 4 and 5 models pack a pixel density of 326 ppi, with individual pixels measuring 78 micrometers. That might seem plenty good enough given the average human eye is unable to differentiate between the individual pixels, but scientists in the UK have now developed technology that could lead to extremely high-resolution displays that put such pixel densities to shame." -
Slashdot Asks: Do You Want a Smart Watch?
Watches that do more than tell the time have been around for a long time. (And in fiction, James Bond, Dick Tracey, and Michael Knight all had notably high-tech watches.) The new smart watches from Samsung and LG, without a phone connected via Bluetooth as backhaul, can still serve to show the time and to serve as alarms (and Samsung's can measure your pulse, too), but all the magic features (like searching by voice via the watch) do require a connection. They can't play MP3s or take pictures on their own, and they don't have built-in GPS. Even so, compared to the polarizing Google Glass, the new breed of smart watches are wearables that probably are an easier sell, even if this far the trend has been to replace watches with smart phones. (Android Wear has gotten a lot of attention, but Microsoft has their own upcoming, and Apple almost certainly does, too.) Are you interested in a smart watch, and if so, what uses do you want it for? If they have no appeal to you now, are there functions that would make you change your mind on that front? -
Sand-Based Anode Triples Lithium-Ion Battery Performance
Zothecula (1870348) writes "Conventional lithium-ion batteries rely on anodes made of graphite, but it is widely believed that the performance of this material has reached its zenith, prompting researchers to look at possible replacements. Much of the focus has been on nanoscale silicon, but it remains difficult to produce in large quantities and usually degrades quickly. Researchers at the University of California, Riverside have overcome these problems by developing a lithium-ion battery anode using sand." -
Radical Dual Tilting Blade Helicopter Design Targets Speeds of Over 270mph
Zothecula writes: As one of the contenders in the race to win a $100 billion contract from the U.S. government for the next generation of attack helicopter in the Army's Joint Multi-Role Technology Demonstrator (JMR-TD) program, AVX Aircraft Company has conceived a futuristic machine kitted out with coaxial rotors, ducted fans and a retractable undercarriage that could hit speeds of over 270 mph (435 km/h). -
Airbus Patents Windowless Cockpit That Would Increase Pilots' Field of View
Zothecula writes Imagine showing up at the airport to catch your flight, looking at your plane, and noticing that instead of windows, the cockpit is now a smooth cone of aluminum. It may seem like the worst case of quality control in history, but Airbus argues that this could be the airliner of the future. In a new US patent application, the EU aircraft consortium outlines a new cockpit design that replaces the traditional cockpit with one that uses 3D view screens instead of conventional windows. -
Polymer-Based Graphene Substitute Is Easy To Mass-Produce
Zothecula writes: For all the attention graphene gets thanks to its impressive list of properties, how many of us have actually encountered it in anything other than its raw graphite form? Show of hands. No-one? That's because it is still difficult to mass-produce without introducing defects. Now a team at the Korea Institute of Science and Technology has developed a graphene substitute from plastic that offers the benefits of graphene for use in solar cells and semiconductor chips, but is easy to mass-produce (abstract). -
Researchers Create Walking, Muscle-Powered Biobots
Zothecula writes If you're going to deploy robots in biological settings – for example, inside the body – it makes a lot of sense to build those robots out of actual biological body parts. Muscle, for example, is a very effective, biodegradable replacement for an electric actuator that can run in a nutrient-rich fluid without the need for any other power source. Bio-robotics experts in Illinois have demonstrated a bio-bot built from 3-D printed hydrogel and spinal muscle tissue that can "walk" in response to an electrical signal. Their next step will be trying to incorporate neurons that can get the bot walking in different directions when faced with different stimuli. -
Solar-Powered Electrochemical Cell Used To Produce Formic Acid From CO2
Zothecula writes Rising atmospheric CO2 levels can generally be tackled in three ways: developing alternative energy sources with lower emissions; carbon capture and storage (CCS); and capturing carbon and repurposing it. Researchers at Princeton University are claiming to have developed a technique that ticks two of these three boxes by using solar power to convert CO2 into formic acid. With power from a commercially available solar panel provided by utility company Public Service Electric and Gas (PSE&G), researchers in the laboratory of Princeton professor of chemistry Andrew Bocarsly, working with researchers at New Jersey-based start-up Liquid Light Inc., converted CO2 and water to formic acid (HCOOH) in an electrochemical cell.
