Zothecula writes "In the quest to develop implantable electronics to monitor the human body from within, flexibility and stretchability have been major hurdles. We've seen numerous developments including stretchable LED arrays, an implantable device for measuring the heart's electrical output, and an electrode array that melts onto the surface of the brain. Now researchers have developed technology that combines a porous polymer and liquid metal that allows electronics to bend and stretch to more than 200 percent their original size (abstract)."

Zothecula writes "For over 30 years, the $250,000 for the American Helicopter Society's Igor I. Sikorsky Human Powered Helicopter Competition prize has looked decidedly secure, but Gamera II has changed all that. Last week, Clark School of Engineering team pilots came close to breaking one of the competition's major milestones. Ph.D. candidate from Kyle Gluesenkamp from the School's mechanical engineering department, hand-cranking and pedaling like his life depended on it, managed to keep the huge quad-rotor craft aloft for 50 seconds, an impressive new world record that's currently awaiting validation by the National Aeronautic Association (NAA)." We previously covered their attempt to break the record last May.

Zothecula writes "Although the SpaceX Dragon spacecraft was unmanned during its recent first flight to the International Space Station, the success of that mission marked a huge step toward future crewed commercial space flights. SpaceX, of course, isn't the only player in this newly-forming industry – companies such as Virgin Galactic, Boeing, and Blue Origin are also hoping to take paying customers on rocket rides. However, while a lot of attention has been paid to the spacecraft themselves, one has to wonder what those private-sector astronauts will be wearing. Expensive NASA space suits, perhaps? Not if Ted Southern and Nikolay Moiseev have anything to say about it."

Zothecula writes "If you've ever worn a knee brace, then you may have noticed what a large change in angle your knee goes through with every step you take, and how quickly it does so. A team of scientists from the U.K.'s Cranfield University, University of Liverpool and University of Salford certainly noticed, and decided that all that movement should be put to use. The result is a wearable piezoelectric device that converts knee movement into electricity, which could in turn be used to power gadgets such as heart rate monitors, pedometers and accelerometers."

cylonlover writes "We've heard reports that placing small, reflective particles into the upper atmosphere could actually improve crop yields, but would also significantly reduce the amount of electricity generated by solar power plants and do little to arrest the acidification of the world's oceans. Now another potential side effect has been theorized by Californian researchers, who say that solar geoengineering could lead to brighter, whiter skies, and sunsets with an afterglow (abstract)."

Zothecula writes with an update on NASA's lunar mapping probes. From the article: "After entering orbit around the Moon at the start of the year, NASA's twin GRAIL probes, Ebb and Flow, have completed their primary mission to study the Moon's interior structure ahead of schedule. Operating around the clock since March 8, NASA says the spacecraft have provided unprecedented detail about the interior structure and evolution of the Moon and the data they have gathered will provide insights into how Earth and its rocky neighbors in the inner solar system developed." And their extended mission? From NASA: "The extended mission goal is to take an even closer look at the moon's gravity field. To achieve this, GRAIL mission planners will halve their current operating altitude to the lowest altitude that can be safely maintained. 'Orbiting at an average altitude of 14 miles (23 kilometers) during the extended mission, the GRAIL twins will be clearing some of the moon's higher surface features by about 5 miles (8 kilometers),' said Joe Beerer of JPL, GRAIL's mission manager."

cylonlover writes news of ion based logic gates. From the article: "While the silicon chips found in the electronic devices that we rely on every day are built around the flow of electrons through circuits, with the development of an 'integrated chemical chip,' a doctoral student in Organic Electronics at Sweden's Linköping University has created the basis for an entirely new circuit technology based on the transmission of ions and molecules. Like silicon-based chips, the integrated chemical chip contains logic gates, such as NAND gates, that form the basis of digital electronics by allowing for the construction of all logical functions."

cylonlover writes "Last year, NASA revealed it was evaluating three potential 'tractor beam' technologies to deliver planetary or atmospheric particles to a robotic rover or orbiting spacecraft. At the time, the third of these, which involved the use of a Bessel beam, only existed on paper. Researchers at Singapore's Agency for Science, Technology and Research (A*STAR) have now proven the theory behind the concept, demonstrating how a tractor beam can be realized in the real world – albeit on a very small scale (abstract)."

cylonlover writes, quoting Gizmag: "Generally speaking, companies developing suborbital manned vehicles brag about how much elbow room their spacecraft will provide passengers. They say there will be plenty of room to float around during the weightless portion of the flight, that there will be no fighting for windows, that passengers will comfortably endure the high-g portions of the flight ... and then there's Copenhagen Suborbitals' Tycho Brahe. CS's Tycho Brahe is a one-passenger capsule intended for a purely ballistic flight to a peak altitude approaching 100 miles. The passenger is just along for the ride, with no mechanism to steer or otherwise pilot the capsule."

Zothecula writes "SpaceX and Bigelow Aerospace have joined forces in an attempt to woo international customers looking to enjoy some extended periods of microgravity. The joint marketing effort will push trips to orbiting Bigelow habitats on SpaceX's Dragon spacecraft using the Falcon launch vehicle. 'Bigelow's BA 330 space module would be designed to provide 330 cubic meters of usable volume, which is about the size of a two-bedroom apartment. The BA 330 could accommodate up to six astronauts, depending on how cozy they plan to get. Two or more BA 330 modules could be connected together in orbit for lease by national space agencies, companies or universities, according to Bigelow Aerospace.'"

cylonlover writes "The hashtag or "#" symbol has taken on a lot more use in recent years, especially with the rise of social media tools like Twitter, where it's used to highlight popular topics. So in a way, it's a fitting model for an apartment building designed to act as a self-contained neighborhood, which is exactly the idea behind the Cross # Towers planned for South Korea. Dutch architectural firm, Bjarke Ingels Group (BIG), is modeling the look of the proposed building after the familiar symbol, by placing two interlocking bridges between two skyscrapers, which will also support outdoor park areas to mimic the sort of spaces you'd normally find on the ground."

cylonlover writes "A University of Dundee research team led by Prof. Mike MacDonald has demonstrated that both levitation and twisting forces can be applied to an object by application of ultrasonic beams. The team of physicists at the University of Dundee in Scotland (with associates at Bristol University in England) have succeeded in generating an ultrasonic vortex beam strong enough to lift and rotate a rubber disk submerged in water. This latest breakthrough is part of a wide-ranging U.K. research effort to develop a device not unlike the "sonic screwdriver" made famous by the TV series Doctor Who." We covered the beginning of the sonic screwdriver project by Bristol University engineers a little over a year ago.

Zothecula writes, quoting Gizmodo "While the Moon may or may not contain life forms, precious metals or even green cheese, recent satellite missions have indicated that it does nonetheless contain something that could prove quite valuable — water ice. NASA has estimated that at least 650 million tons (600 million tonnes) of the stuff could be deposited in craters near the Moon's north pole alone. If mined, it could conceivably serve as a source of life support for future lunar bases, or it could be used to produce fuel for spacecraft stopping at a "lunar gas station." Before any mining can happen, however, we need to learn more about the ice. That's why NASA has contracted Pittsburgh-based Astrobotic Technology to determine if its Polaris rover robot could be used for ice prospecting."

Zothecula writes "Crowd-funding sites like Kickstarter have proven popular for groups and individuals looking to get a consumer product, movie, music or video game project off the ground. Now a group of researchers and scientists is adopting a similar crowd-funding model to raise money for scientific research projects. The Microryza website, which launched this week, lets the public get behind research they care about and maybe help it get out of the lab."

Cazekiel writes "Sticking a mug in your freezer to ensure a cold beer may be made obsolete, if the Japanese brewing giant Kirin has anything to do about it. How? Kirin came up with a way to create frozen beer foam, dispensed the way you would a soft-serve ice cream cone. Gizmag gives us the details: 'To make the topping, regular Ichiban beer is frozen to -5 degrees Celsius (23 degrees Fahrenheit) while air is continuously blown into it. It's kind of like when a child makes bubbles in their drink, except inside a blast freezer. Once the topping is placed onto regular, unfrozen beer though, it acts as an insulating lid and keeps the drink cold for 30 minutes.'" Might make flavorless rice lagers easier to go down, but what about real beer? A hefeweizen under an ice cap on a warm summer afternoon? How about an entire glass full of frozen chocolate stout?

cylonlover writes "While games like Batman: Arkham City and Gears of War are certainly entertaining, virtually beating up thugs and fighting subterranean creatures doesn't exactly translate into real world skills. However, a new agreement with teaching software developer Virtual Heroes could see Epic's Unreal Engine platform used to create more practical experiences and train medical staff and law enforcement officers to handle high-stress situations. By using Epic's Unreal Engine 3, some United States government agencies like the FBI and U.S. Army are hoping to give their employees tools for virtually practicing their skills in a more realistic environment and better prepare them to save lives."

cylonlover writes "An international team of scientists has created a handheld, battery powered device that has been shown to effectively rid skin of bacteria in an instant by blasting it with plasma. The plasma flashlight, which shouldn't be confused with a plasma torch that will damage much more than bacteria if used on the skin, could provide a convenient way for paramedics and military personnel to deal with harmful bacteria in the field. The self-contained device is powered by a 12 V battery and doesn't require any external gas feed or handling system. The plume of plasma it generates is between 20-23C (68-73.4F), so it won't damage the skin. It is also fitted with resistors to stop it heating up and becoming too hot to touch. Its creators say it can also be easily manufactured at a cost of less than US$100 per unit."

cylonlover writes "In an effort to provide a more accurate alternative to conventional cell culture and animal models, researchers at the Wyss Institute for Biologically Inspired Engineering at Harvard University have developed a microdevice that mimics the structure, physiology, and mechanics of the human intestine. The so-called 'gut-on-a-chip' could help provide new insights into intestinal disorders and be used to evaluate the safety and efficacy of potential treatments."

Zothecula writes with news involving space and lasers. From the article: "A collision between Earth and an asteroid a few kilometers in diameter would release as much energy as the simultaneous detonation of several million nuclear bombs, and with the impact of an asteroid estimated at around 10 km (6.2 miles) in diameter believed to be responsible for wiping out the dinosaurs, numerous strategies have been devised to try and avoid such devastation. The latest idea comes from engineers at Glasgow's University of Strathclyde who suggest that a swarm of laser-wielding satellites could nudge Earth-bound asteroids off their collision course."

Zothecula writes "While it's generally accepted that memories are stored somewhere, somehow in our brains, the exact process has never been entirely understood. Strengthened synaptic connections between neurons definitely have something to do with it, although the synaptic membranes involved are constantly degrading and being replaced – this seems to be somewhat at odds with the fact that some memories can last for a person's lifetime. Now, a team of scientists believe that they may have figured out what's going on. Their findings could have huge implications for the treatment of diseases such as Alzheimer's."

Zothecula writes "With the space shuttle program now officially over, the United States needs a new reusable vehicle for getting supplies to and from the International Space Station. NASA is considering the Dragon spacecraft, designed by California-based SpaceX Exploration Technologies, to take over that role. The Dragon's scheduled late March/early April test flight to the ISS will be unmanned, utilizing a cargo configuration of the spacecraft. Last Friday, however, SpaceX released photographs of an engineering model of its planned seven-passenger crew cabin, complete with a crew that included real, live astronauts."

Zothecula writes "A throwback to early 20th century aviation may hold the key to eliminating the sonic boom — at least according to researchers at MIT and Stanford University. Strongly reminiscent of biplanes still in use today, the researcher's concept supersonic aircraft introduces a second wing which, it is claimed, cancels the shockwaves generated by objects near or beyond the sound barrier."

cylonlover writes "Because everyone's immune system is different, it's impossible to predict with absolute certainty how any given person will react to a specific medication. In the not-too-distant future, however, at-risk patients may get their own custom-altered mouse, with an immune system that's a copy of their own. Medications could be tried out on the mouse first, and if they are shown to have no adverse effects, the person could take the medication with a higher degree of confidence. If the person has an autoimmune disease, the mouse could also provide valuable insight into its treatment. A team led by Columbia University Medical Center's Dr. Megan Sykes has recently developed a method of creating just such a 'personalized immune mouse.'"

cylonlover writes "Imagine a pair of rubber gloves whose surface texture could be altered on demand to provide more grip for climbing. Or maybe gloves with "fingerprints" that can be changed in the blink of an eye. They are just a couple of the many potential applications envisioned by researchers at Duke University for a process they have developed that allows the texture of plastics to be changed at will. By applying specific voltages, the researchers have been able to dynamically switch polymer surfaces among various patterns ranging from dots, segments, lines to circles."

Gaygirlie writes "An article over at Gizmag says: 'It's a meme that's been doing the rounds on the internet in recent years: multi-word pass-phrases are as secure as long strings of gibberish but with the added benefit of being easy to remember. But research from Cambridge University suggests that this may not be the case. Pass-phrases comprised of dictionary words may not be as vulnerable as individual passwords, but they may still succumb to dictionary attacks, the research finds.' I find this to be twisting of words and general consensus; of course any password whatsoever is going to be insecure against offline attack, and using common, popular words is going to make guessing the password much easier. But is this really an issue in a world where most attacks are done online? Should general populace still be coaxed into using randomly generated passwords?"

cylonlover writes "Today's weather on HD 189733b: It will be hazy with high wispy clouds. The wind will be steady from the east at speeds approaching 6,000 miles per hour (9,656 km/h). Daytime temperatures will average a balmy 800C (1,472F), while the equatorial hot spot at 30 degrees longitude is expected to top 900C (1,652F). But, there is a high chance of silicate snow showers, with accumulations expected except in the vicinity of the hot spot. Just how much can astronomical observations tell us about exoplanets — those worlds orbiting other stars in our galaxy? With patience and cunning, more than you might think."

Zothecula writes "Not too long ago, brothers Randy and Michael Gregg were out on a hunting expedition. It was the day after deer season had ended, yet they spied a handsome animal bedded down in the snow. Not wanting to pass up an opportunity, they silently crept up on their quarry, raised their rifle, lined the deer up in the crosshairs ... and then took a picture through the scope with a mobile phone. That photo provided all the proof they needed that they had successfully stalked their prey, without bringing home an illegally-obtained carcass. It also inspired them to create the Kill Shot — a replica hunting rifle, that takes pictures instead of firing bullets." The Kill Shot isn't just for hunters. Think of how great this would be at sporting events or family reunions!

Zothecula writes "Getting into space is one of the harder tasks to be taken on by humanity. The present cost of inserting a kilogram of cargo by rocket into Low Earth Orbit (LEO) is about US$10,000. A manned launch to LEO costs about $100,000 per kilogram of passenger. But who says we have to reach orbit by means of rocket propulsion alone? Instead, imagine sitting back in a comfortable magnetic levitation train and taking a train ride into orbit."

cylonlover writes "When Chaotic Moon Labs debuted the Kinect-powered Board of Awesomeness — and its mind-reading offspring, the Board of Imagination — that was apparently just a preview of a more practical product the company had in the works. Grocery store chain Whole Foods recently gave a demonstration of Chaotic Moon's latest device, which uses the same technology in a self-propelled shopping cart. The 'Smarter Cart,' as it's been named, can detect what items are placed in it, match those to a shopping list, and even follow shoppers around the store on its own."

cylonlover writes "Scientists at Sandia National Laboratories have announced a breakthrough in prosthetics that may one day allow artificial limbs to be controlled by their wearers as naturally as organic ones, as well as providing sensations of touch and feeling. The scientists have developed a new interface consisting of a porous, flexible, conductive, biocompatible material through which nerve fibers can grow and act as a sort of junction through which nerve impulses can pass to the prosthesis and data from the prosthesis back to the nerve. If this new interface is successful, it has the potential to one day allow nerves to be connected directly to artificial limbs."

cylonlover writes "Joint implants should always be made of materials like titanium, so they can last the lifetime of the patient ... right? Well, not according to researchers at Finland's Tampere University of Technology. They've developed a product known as RegJoint, which is reportedly the world's first biodegradable joint implant. Unlike permanent implants, it allows the patient's bone ends to remain intact, and it creates a new joint out of their own tissue."

cylonlover writes "A strong and highly selective instant adhesive inspired by the bacterium Streptococcus pyogenes has been developed by Oxford University researchers. S. pyogenes is a common resident of human throats that is normally kept in check by the body's defenses, but when it gets out of control it can cause diseases ranging from strep throat to toxic shock syndrome or flesh-eating disease. By engineering a protein that is central to S. pyogenes' infectious arsenal, the researchers have developed a new superglue that can't be matched for sticking molecules together and not letting go."

Zothecula writes "It is a great irony that alcohol should be legislated into becoming man's most commonly used recreational drug, as it's the only drug that causes more harm to others than to the user. This is most evident on our roads, where even in first world countries with low road tolls, alcohol still accounts for between a third and a half of road deaths. Now France is to attempt a novel solution — from July of this year, it will become law in France to have a working breathalyzer in every car on the road, with enforcement beginning November 1."

cylonlover writes "With the wait still on for a miniaturization ray to allow some Fantastic Voyage-style medical procedures by doctors in submarines, tiny electronic implants capable of traveling in the bloodstream show much more promise. While the miniaturization of electronic and mechanical components now makes such devices feasible, the lack of a comparable reduction in battery size has held things back. Now engineers at Stanford University have demonstrated a tiny, self-propelled medical device that would be wirelessly powered from outside the body, enabling devices small enough to move through the bloodstream."

Zothecula writes "If you thought WikiLeaks was a disruptive idea, the transparency grenade is going to blow you away. This tiny bit of hardware hidden under the shell shaped like a classic Soviet F1 hand grenade allows you to leak information from anywhere just by pulling a pin. The device is essentially a small computer with a powerful wireless antenna and a microphone. Following 'detonation,' the grenade intercepts local network traffic and captures audio data, then makes the information immediately available online."

Zothecula writes "Oxford Nanopore has been developing a disruptive nanopore-based technology for sequencing DNA, RNA, proteins, and other long-chain molecules since its birth in 2005. The company has just announced that within the next 6-9 months it will bring to market a fast, portable, and disposable protein sequencer that will democratize sequencing by eliminating large capital costs associated with equipment required to enter the field."

cylonlover writes "This year is a historic one for nuclear power, with the first reactors winning U.S. government approval for construction since 1978. Some have seen the green lighting of two Westinghouse AP1000 reactors to be built in Georgia as the start of a revival of nuclear power in the West, but this may be a false dawn because of the problems besetting conventional reactors. It may be that when a new boom in nuclear power comes, it won't be led by giant gigawatt installations, but by batteries of small modular reactors (SMRs) with very different principles from those of previous generations. However, while it's a technology of great diversity and potential, many obstacles stand in its path. This article takes an in-depth look at the many forms of SMRs, their advantages, and the challenges they must overcome."

Zothecula writes "Inspired by origami and children's pop-up books, Harvard engineers have pioneered a means of mass-producing bee-sized flying microrobots. The breakthrough mechanizes the already state-of-the art process of making Harvard's Mobee robots by hand, by mass producing flat assemblies by the sheet which can be folded and assembled in a single movement. The technique, which cunningly exploits existing machinery for making printed circuit boards, can theoretically be applied to a multitude of electromechanical machines."

Zothecula writes "The European Space Agency's new Vettore Europeo di Generazione Avanzata — or Vega — launch vehicle lifted off from Europe's Spaceport in Kourou, French Guiana, at 10 a.m. GMT on February 13 on its maiden flight. Designed for launching small payloads, Vega is intended to complement Europe's existing family of launchers that includes the Ariane 5 heavy-lifter and Soyuz medium-class launchers. The qualification flight, designated VV01, saw the first Vega successfully carry nine satellites into orbit."

cylonlover writes "Besides having to remove our shoes, the volume limitations regarding liquids and gels in carry-on baggage has become a major hassle in the world of post 9-11 airport security. Hopefully, however, we may soon be able to once again bring our big bottles of water and tubes of toothpaste aboard airliners in our overnight bags. Britain's Cobalt Light Systems has developed a scanner called the INSIGHT100, that uses laser light to assess the liquid contents of containers, even if those containers are opaque."

Zothecula writes "Some readers might remember the Mr. Fusion unit in Back to the Future that Doc Brown fills with household garbage, including a banana peel and some beer, to power the iconic time-traveling DeLorean. While we're still some way from such direct means of running our cars on table scraps, researchers at Fraunhofer have developed a pilot plant that ferments the waste from wholesale fruit and veg markets, cafeterias and canteens to make methane, which can be used to power vehicles."

Zothecula writes "Two years after BAE Systems was awarded a US$21 million contract from the Office of Naval Research (ONR) to develop an advanced Electromagnetic Railgun for the U.S. Navy, the company has delivered the first industry-built prototype demonstrator to the Naval Surface Warfare Center (NSWC) Dahlgren. The prototype launcher is now being prepared for testing which is scheduled to take place in the coming weeks."

Zothecula writes "Research scientist Andreas Mershin has a dream to bring inexpensive solar power to the masses, especially those in developing countries. After years of research, he and his team at MIT's Center for Bits and Atoms, along with University of Tennessee biochemist Barry Bruce, have worked out a process that extracts functional photosynthetic molecules from common yard and agricultural waste. If all goes well, in a few years it should be possible to gather up a pile of grass clippings, mix it with a blend of cheap chemicals, paint it on your roof and begin producing electricity. Talk about redefining green power plants!"

cylonlover writes "SpaceX, the California company that is developing the reusable Dragon spacecraft, recently test-fired its new SuperDraco engine. Presently, the Dragon capsule is equipped with less-advanced Draco engines, which are designed for maneuvering the spacecraft while in orbit and during reentry. The SuperDraco, however, is intended to allow the astronauts to escape if an emergency occurs during the launch."

Zothecula writes "Last year, NASA announced it was seeking proposals for mission concept studies of a high-power solar electric propulsion (SEP) system that could be used in a 'space tugboat.' Such a ship would be used to ferry payloads in low Earth orbit (LEO) into higher energy orbits, including geosynchronous Earth orbit (GEO) and Lagrange point one (L1) — saving on fuel and the use of expensive secondary boosters. NASA also anticipates an SEP system could be used to propel spacecraft into deep space for science missions and for the placement, service, resupply, repositioning and salvaging of space assets by commercial operators."

New submitter jpwilliams writes "Gizmag reports that researchers at Sandia National Laboratories have tested a 10-centimeter bullet that can be fired from a smooth-bore rifle to hit a laser-marked target one mile away. The bullet 'includes an optical sensor in the nose to detect a laser beam on a target. The sensor sends information to guidance and control electronics that use an algorithm in an eight-bit central processing unit to command electromagnetic actuators. These actuators steer tiny fins that guide the bullet to the target.' Interestingly, accuracy improves with targets that are further away, because 'the bullet's motions settle the longer it is in flight.'"

Zothecula writes "You don't need to be an expert in occupational safety to know that worker fatigue is one of the leading causes of workplace accidents — this particularly applies to people who operate heavy machinery or drive for a living. While it would be great if all employees simply took a break when fatigue started setting in, it can sometimes be difficult for people to tell just how tired they really are. That, or they decide that they just want to push through and get the job done, drowsiness be damned. An invention from Australia's EdanSafe, however, takes the guesswork out of the picture. It's called the SmartCap, and it measures employee fatigue in real time by monitoring its wearer's brain waves."

cylonlover writes with an excerpt from a Gizmag article: "The cell membrane is one of the most important components of a cell because it separates the interior from the environment and controls the movement of substances in and out of the cell. In a move that brings mankind another step closer to being able to create artificial life forms from scratch, chemists from the University of California, San Diego (UCSD), and Harvard University have created artificial self-assembling cell membranes using a novel chemical reaction. The chemists hope their creation will help shed light on the origins of life." The full paper is available in the Journal of the American Chemical Society (behind a paywall).

Zothecula writes "Facial recognition might be all the rage in giving computer systems the ability to ascertain the identity of individuals — what with most people having different facial features and all. But a team from the Hasso Plattner Institute in Potsdam, Germany, has taken a different approach to identify users of touch-based tabletop computers like Microsoft's Surface. Instead of focusing on the face, the team has looked in the opposite direction to develop a system known as Bootstrapper, which distinguishes between users based on their footwear ."
