Submission + - Potentially Very-Useful "Polymer Opals" Change Color When Stretched (gizmag.com)

Zothecula writes: Some of the most vividly colored materials in nature, including things like butterfly wings, don’t obtain their color from pigment. Instead, their internal structure reflects light at a given wavelength, producing a specific color. Opals are another example of something that utilizes this effect. In collaboration with Germany’s Fraunhofer Institute for Structural Durability and System Reliability, scientists from the University of Cambridge have now copied the colorful nanostructure of the opal. The result is a flexible, colorful material that won’t fade over time, that changes color when stretched, and that could have many applications.

Submission + - Avatars Help Schizophrenics Gain Control of Voices in Their Heads (gizmag.com)

Zothecula writes: Imagine if there was a voice in your head that regularly threatened to harm you or your loved ones, or that even ordered you to do so yourself. Awful as that would be, such auditory hallucinations are one of the most common symptoms of schizophrenia, with approximately one in four sufferers continuing to experience them even once taking anti-psychotic drugs. Fortunately, scientists have recently helped some schizophrenics gain control of their condition, by turning those voices into interactive avatars.

Submission + - Genetically-Engineered Mosquitoes Lose Nose for Humans (gizmag.com)

Zothecula writes: It has long been believed that detecting carbon dioxide was one of the ways that mosquitoes target their human prey. But the fact that mosquitoes tend to favor certain people over others indicates that some other odor also plays a part in the attraction. Researchers at the Howard Hughes Medical Institute (HHMI) have genetically engineered mosquitoes to alter their sense of smell, which could provide the understanding required to block the pesky pests' attraction to humans.

Submission + - Stanford's Flying Fish Glider Bests Ordinary Jumping Robots (gizmag.com)

Zothecula writes: Researchers at Stanford University have developed a small "aircraft" that resembles a flying fish which can jump and glide over a greater distance than an equivalent jumping robot. Using a carbon fiber spring to take off, the jumpglider has a pivoting wing that stays out of the way during ascent, but which locks into place to glide farther on the way down.

Submission + - CurvACE Gives Robots a Bug's Eye View (gizmag.com)

Zothecula writes: Robots are getting down to the size of insects, so it seems only natural that they should be getting insect eyes. A consortium of European researchers has developed the artificial Curved Artificial Compound Eye (CurvACE) which reproduces the architecture of the eyes of insects and other arthropods. The aim isn't just to provide machines with an unnerving bug-eyed stare, but to create a new class of sensors that exploit the wide field of vision and motion detecting properties of the compound eye.

Submission + - Mataerial 3D Printer Builds Gravity-Defying Structures Directly Onto Walls (gizmag.com)

Zothecula writes: Earlier this year, we heard about the 3Doodler, a pen that lets users sketch 3D objects with plastic filament, almost like a 3D printer. It's a fun little gadget, but what if someone made a device that offers similar freedom, except it built objects over 10 times larger? It might look something like the Mataerial 3D printer, which uses a robotic arm and quick-solidifying material to form rigid, free-flowing structures on almost any surface, even vertical ones.

Submission + - IBM's Watson Gets a Job in Customer Service (gizmag.com)

Zothecula writes: IBM’s Watson supercomputer has been riding high for the past couple of years. It won a game of Jeopardy, went to university and did a stint at a cancer lab. But now it’s taking what might seem like a step down with a job in customer service. According to IBM, the current avalanche of information is provoking an oncoming crisis in customer service and the company sees Watson’s advanced learning and data crunching abilities as a solution.

Submission + - Scientists Grow Microscopic Flowers by Controlling Crystal Formation (gizmag.com)

Zothecula writes: When we think of crystals, most of us probably either picture spiky things like snowflakes, or cube-shaped objects like grains of sugar. Researchers from the Harvard School of Engineering and Applied Sciences, however, have recently coaxed barium carbonate crystals to grow into very miniature replicas of soft, curved flowers.

Submission + - Christie's Putting 1950s Vintage Cygan Robot Under the Hammer (gizmag.com)

Zothecula writes: Most modern robots look nothing like those predicted by 1950's era science fiction. But if you’re in the market for a retro-style robot with world-domination-worthy looks you might want to dust off your auction paddle. Christie’s auction house is putting the vintage robot Cygan on the block as part of its Out of the Ordinary sale on September 5.

Submission + - Nanoscavengers Could Be the Next-Gen Water Purifiers (gizmag.com)

Zothecula writes: According to a joint World Health Organization/UNICEF report issued this week, an estimated 768 million people relied on unimproved drinking-water sources in 2011, with 185 million of these relying on surface water to meet their daily drinking-water needs. WHO and UNICEF have set a 2030 target for everyone to have access to a safe drinking-water supply and new water-purifying “nanoscavengers” developed by researchers at Stanford University could help achieve this goal.

Submission + - D-Wave Quantum Computer Matches the Tenth Ranked Supercomputer for Speed (gizmag.com)

Zothecula writes: There have been years of controversy about whether the superconducting quantum annealing computers manufactured by D-Wave are a) quantum computers; and b) fast enough for a) to matter. Now a test of the 512-qubit Vesuvius chip establishes at least that computing based on quantum annealing is, in the words of a computer science professor at Amherst College, "in some cases, really, really fast."

Submission + - Hand-held "Sound Camera" Shows You the Source of Noises (gizmag.com)

Zothecula writes: If you work with machinery, engines or appliances of any type, then you’ve likely experienced the frustration of hearing a troublesome noise coming from somewhere, but not being able to pinpoint where. If only you could just grab a camera, and take a picture that showed you the noise’s location. Well, soon you should be able to do so, as that’s just what the SeeSV-S205 sound camera does.

Submission + - Humans Hack Space in the International Space Apps Challenge (gizmag.com)

Zothecula writes: Given a set of problems related to space exploration and a 48-hour deadline, 9,000 people in 80 locations around the world created over 600 solutions. The International Space Apps Challenge, sponsored by NASA and other international space agencies, offered up massive amounts of data and other resources to teams of hackers who responded with creative solutions. The public now has the chance to view these solutions online and vote for their favorites on each project's official page. Gizmag set out to find the best projects related to data visualization and education, space exploration and satellite inventiveness, green technology, and remotely-operated vehicles.

Submission + - Proba-V Satellite to Track Aircraft Continuously From Space (gizmag.com)

Zothecula writes: When it comes to keeping tabs on the location of aircraft, radar has long ruled the roost. But radar range is limited, and long-haul planes become untraceable when passing over oceans and large deserts or polar regions. By equipping orbiting satellites with instruments that listen in on ADS-B signals, scientists think that it should possible to track aircraft over the course of their entire journey, and with the launch of Proba-V, they're ready to put the idea to the test.
