+ - "Nano-Pixels" Hold Huge Potential For Flexible, Low-Power, High-Res Screens->

Submitted by Zothecula
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."

+ - Sand-Based Anode Triples Lithium-Ion Battery Performance->

Submitted by Zothecula
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."

+ - Student-Designed Device Reduces Gas Lawnmower Air Pollution By Over 90%->

Submitted by Zothecula
Zothecula (1870348) writes "Gas-powered lawnmowers are notorious polluters. According to the US Environmental Protection Agency, running a new gas mower for one hour produces as much air pollution as would be generated by 11 typical automobiles being driven for the same amount of time. Switching to an electric or reel mower is certainly one option, but for those applications where it's gotta be gasoline, a team of engineering students from the University of California, Riverside are developing another: an attachment that they claim reduces noxious emissions by over 90 percent."

Submitted by Zothecula
Zothecula (1870348) writes "As one of the contenders in the race to win a $100 billion contract from the US 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->

Submitted by Zothecula
Zothecula (1870348) 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->

Submitted by Zothecula
Zothecula (1870348) 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 (KIST) 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."

+ - University of Illinois Demonstrates "Walking" Bio-robot->

Submitted by Zothecula
Zothecula (1870348) 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->

Submitted by Zothecula
Zothecula (1870348) 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."

Submitted by Zothecula
Zothecula (1870348) writes "Virtual reality is all the rage these days. Well, that is, apart from the fact that you can't yet buy any of the most talked-about VR hardware. But if a just so crazy it might work Google project has its way, we might all soon be walking around with homemade VR headsets made on the cheap. Meet Google Cardboard."

+ - World's First Large-Scale Waste-to-Biofuels Facility Opens in Canada->

Submitted by Zothecula
Zothecula (1870348) writes "Thanks to its extensive composting and recycling facilities, the city of Edmonton, Canada is already diverting approximately 60 percent of its municipal waste from the landfill. That figure is expected to rise to 90 percent, however, once the city's new Waste-to-Biofuels and Chemicals Facility starts converting garbage (that can't be composted or recycled) into methanol and ethanol. It's the world's first such plant to operate on an industrial scale, and Gizmag recently got a guided tour of the place."

+ - "Bruise Trousers" Are Designed to Let Disabled Athletes Know When They're Hurt-> 1

Submitted by Zothecula
Zothecula (1870348) writes "Along with the obvious mobility issues faced by athletes who are unable to walk, they also face another challenge – if they're unable to feel their legs, that means they can't always tell when they've been hurt. Severe bruises or broken bones can simply go unnoticed, until they develop into even more of a problem. That's why a group of students at Imperial College London have invented a set of "bruise trousers" that show such athletes when and where they've received a serious impact below the waist."

Submitted by Zothecula
Zothecula (1870348) writes "When we think of wind power, we generally think of huge wind turbines sitting high atop towers where they can take advantage of the higher wind speeds. But Maryland-based Solar Wind Energy, Inc. is looking to turn wind power on its head with the Solar Wind Downdraft Tower, which places turbines at the base of a tower and generates its own wind to turn them."

Submitted by Zothecula
Zothecula (1870348) writes "In what is hailed as a world first for robots, a Canadian robot dubbed "hitchBOT" hopes to be the first to hitchhike across Canada this July. Wearing jaunty red boots and yellow garden gloves (with one in a permanent "thumbing a ride" gesture), hitchBOT is going to try to use his good looks and power of speech to convince people to pick him up and drive him from Halifax, Nova Scotia to Victoria, British Columbia."

+ - New Computer Program Wants to Teach Itself Everything About Any Subject->

Submitted by Zothecula
Zothecula (1870348) writes "Word-picture association is one of the basic mechanisms of human memory. As children, it helps us to learn language by verbalizing what we see, as adults it is an invaluable aid to visualizing broader concepts or perhaps helping those with an LBLD (Language-Based Learning Disability). Now researchers from the University of Washington and the Allen Institute for Artificial Intelligence have created the first fully automated computer program named LEVAN that teaches itself everything there is to know about a visual concept by associating words with images."

+ - New Sensor to Detect Food-Borne Bacteria on Site->

Submitted by Zothecula
Zothecula (1870348) writes "According to the CDC, around 48 million people in the US get sick, 128,000 are hospitalized, and 3,000 die as a result of foodborne illnesses every year. One of the main culprits is listeriosis (or listeria), which is responsible for approximately 1,600 illnesses and 260 deaths. Now researchers at the University of Southampton are trialling a device designed to detect the most common cause of listeriosis directly on food preparation surfaces, without the need to send samples away for laboratory testing."
