Submission + - Graphene-Based Audio Devices Allow Communication at Bat Frequencies (gizmag.com)

Zothecula writes: In yet another first for graphene, physicists from the University of California, Berkeley, have employed this versatile material to create ultra-thin, lightweight ultrasonic microphones and speakers that enable high-quality, two-way communication in the audio range normally used by the likes of bats and dolphins.

Submission + - Black Phosphorus Could Spur the Next Wave of Tiny Transistors (gizmag.com)

Zothecula writes: Black Phosphorus Valley, anyone? Scientists searching for a way to cram more transistors onto a chip have been examining the potential of graphene for several years, but graphene isn't the only two-dimensional material on the block. Researchers at McGill University and Université de Montréal have provided insight into another promising candidate that could help chip designers keep pace with Moore's Law – black phosphorus.

Submission + - Optical Device Takes After a Dog's Nose to Sniff Out Disease (gizmag.com)

Zothecula writes: When things in our body go awry, through disease or infection, for example, the types of molecules in our breath can change. These variations have presented researchers around the world with a very real opportunity to detect various conditions, including lung cancer, with unprecedented ease. The latest scientists to start sniffing around this emerging form of medical diagnosis is a team from the University of Adelaide, who are developing a laser instrument inspired by dog's nose that can screen breath samples for signs of unrest.

Submission + - EPFL's CleanSpace One Satellite Will "Eat" Space Junk (gizmag.com)

Zothecula writes: Three years ago, Swiss research institute EPFL announced its plans to build a spacecraft that could grab orbital debris and then carry it back towards Earth, burning up in the atmosphere with it on its way down. Called CleanSpace One, the satellite was depicted at the time as using a claw-like grasping tool. Now, however, EPFL has announced that it will utilize a folding conical net to essentially gobble up bits of space garbage.

Submission + - New Energy Cell Can Store Up Solar Energy for Release at Night (gizmag.com) 1

Zothecula writes: A photoelectrochemical cell (PEC) is a special type of solar cell that gathers the Sun's energy and transforms it into either electricity or chemical energy used to split water and produce hydrogen for use in fuel cells. In an advance that could help this clean energy source play a stronger role within the smart grid, researchers at the University of Texas, Arlington have found a way to store the electricity generated by a PEC cell for extended periods of time and allow electricity to be delivered around the clock.

Submission + - "Nemo's Garden" Grows Terrestrial Crops Underwater (gizmag.com)

Zothecula writes: The stand for the region of Liguria at the Milan 2015 Expo features a project as bizarre-sounding as it is intriguing: an attempt to grow crops underwater, inside air-filled biospheres. It's part of an effort that could prove a low-cost, low-energy solution to grow food in parts of the world where this was not previously possible.

Submission + - 3-D Ultrasonic Fingerprint Scanning Could Strengthen Smartphone Security (gizmag.com)

Zothecula writes: Researchers at the University of California, Davis and Berkeley have managed to miniaturize medical ultrasound technology to create a fingerprint sensor that scans your finger in 3D. This low-power technology, which could improve on the robustness of current-generation capacitive scanners, could soon find its way to our smartphones and tablets.

Submission + - Solar Impulse 2 Breaks Three Records en Route to Hawaii (gizmag.com)

Zothecula writes: Solar Impulse 2 has started smashing records even before the longest leg of its round-the-world flight is complete. At around three quarters of the way to its next touch down in Hawaii, the single-pilot aircraft has broken the world records for longest distance and duration for solar aviation, with the record for longest ever solo flight of any kind thrown in for good measure.

Submission + - Brick-Laying Robot Can Build a Full-Sized House in Two Days (gizmag.com)

Zothecula writes: As robots get smarter, cheaper and more versatile, they're taking on a growing number of challenges – and bricklaying can now be added to the list. Engineers in Perth, Australia, have created a fully working house-building machine that can create the brick framework of a property in just two days, working about 20 times faster than a human bricklayer.

Submission + - Study Suggests That HUD Tech May Actually Reduce Driving Safety (gizmag.com)

Zothecula writes: Cruising at speed down the highway with a heads-up display (HUD) constantly feeding data into your line of sight can make anyone feel like a jet pilot on the road; totally in control of your vehicle and primed to avert any potential danger that comes your way. However, recent studies by the University of Toronto show that the HUD multi-tasking method of vehicle piloting may well not provide the extra margin of safety that we think it does. In fact, according to the researchers, it could be downright dangerous.

Submission + - Robo-mate Exoskeleton Aims to Lighten the Load for Industry (gizmag.com)

Zothecula writes: The development of powered exoskeletons has so far been largely restricted to the laboratory, the military, and areas such as rehabilitation therapy. This kind of technology also has obvious potential in industry, where constant heavy lifting is still very much a part of many working lives. Recently in Stuttgart, the Robo-Mate project unveiled an exoskeleton designed specifically for industrial use that can make 10 kilos feel like 1.

Submission + - Scientists Look at Communicating With Hypersonic Vehicles Using Plasma Resonance (gizmag.com)

Zothecula writes: Returning spacecraft hit the atmosphere at over five times the speed of sound, generating a sheath of superheated ionized plasma that blocks radio communications during the critical minutes of reentry. It's a problem that's vexed space agencies for decades, but researchers at China's Harbin Institute of Technology are developing a new method of piercing the plasma and maintaining communications.

Submission + - Sensor to Detect Earth's Magnetic Field Discovered in an Animal for First Time (gizmag.com)

Zothecula writes: It has been a long-held belief in scientific circles that many creatures navigate across land, through water, and through the skies using the Earth’s magnetic field for guidance. Now scientists and engineers working at The University of Texas at Austin (UT) have finally discovered the organic mechanism responsible for this in an animal. Looking just like a microscopic TV antenna, the structure has been found in the brain of a tiny earthworm that uses it to work out which way to burrow through the soil. This breakthrough may help scientists discover how other species with internal compasses use the magnetic field of our planet to pilot their course.

Submission + - Inkless Printing Manipulates Light at the Nanoscale to Produce Colors (gizmag.com)

Zothecula writes: Using nanometer-size metamaterials, researchers at Missouri University of Science and Technology have developed a technique to print images that uses the manipulation of light, rather than the application of ink, to produce colors. This "no-ink" printing method has been demonstrated by producing a Missouri S&T athletic logo just 50 micrometers wide.

Submission + - Graphene Used to Create World's Thinnest Light Bulb (gizmag.com)

Zothecula writes: Over 130 years ago, Thomas Edison used carbon as the conducting filament in the very first commercial light bulb. Now a team of scientists and engineers have used that very same element, in its perfectly crystalline form of graphene, to create what they claim is the world's thinnest light bulb. Even though just one atom thick and covering an area almost too small to see unaided, the new device is so bright that the light it produces can easily be seen with the naked eye.
