Firms buy specific keywords, including competitors’ brand names, on search engines such as Google or Bing to reach consumers searching for those words. Online advertisements employing such keywords are called search ads. This practice can backfire, however. A new study shows that any large difference in reputation between the two brand names is further magnified in the minds of consumers.
Developmental processes in all living organisms are controlled by genes. At the same time there is a continuous metabolism taking place. Recent research in Austria has analyzed this interaction in flowering plants. For the first time, changes in metabolism were linked to 3-D morphometric data using micro-computed tomography (micro-CT) for the first time.
Scientists in Israel have recently constructed, for the first time, a photonic router that enables routing of single photons by single photons. At the core of the device is an atom that can switch between two states. The state is set just by sending a single particle of light, or photon, from the right or the left via an optical fiber. The innovation could help overcome difficulties in building quantum computers.
A cheap, portable, microchip-based test for diagnosing type-1 diabetes could speed up diagnosis and enable studies of how the disease develops. Handheld microchips distinguish between the two main forms of diabetes mellitus, which are both characterized by high blood-sugar levels but have different causes. Until now, making the distinction has required a slow, expensive test available only in sophisticated healthcare settings.
According to recent research in the U.K. , use of electronic health records to understand the best available treatment for patients, from a range of possible options, is more efficient and less costly for taxpayers than the existing clinical trial process.
Lighting is crucial to the art of photography, but they are cumbersome and difficult to use properly. Researchers at Massachusetts Institute of Technology and Cornell Univ. aim to change that by providing photographers with squadrons of small, light-equipped autonomous robots that automatically assume the positions necessary to produce lighting effects specified through a simple, intuitive, camera-mounted interface.
The South Korean display panel maker LG has developed an 18-inch flexible display that can be rolled into the shape of a thin cylinder, a step toward making a large display for flexible TVs. Although not as sharp as the latest ultra-high definition flat screens, the new display has a resolution of 1200 pixels by 810 pixels and maintains its function when it is rolled up.
The solar panels that Idaho inventor Scott Brusaw has built aren't meant for rooftops. They are meant for roads, driveways, parking lots, bike trails and, eventually, highways. Brusaw, an electrical engineer, says the hexagon-shaped panels can withstand the wear and tear that comes from inclement weather and vehicles, big and small, to generate electricity.

The R&D 100 Awards recognize excellence across a wide range of industries...
Nuclear engineers at Oregon State Univ. have developed a small, portable and inexpensive radiation detection device that should help people all over the world better understand the radiation around them, its type and intensity and whether or not it poses a health risk.
Scientists at Stanford Univ. and the Dept. of Energy (DOE)’s SLAC National Accelerator Laboratory have found a way to estimate uncertainties in computer calculations that are widely used to speed the search for new materials for industry, electronics, energy, drug design and a host of other applications. The technique, reported in Science, should quickly be adopted in studies that produce some 30,000 scientific papers per year.
The Georgia Tech Research Institute’s software-defined, electronically reconfigurable Agile Aperture Antenna (A3) has now been tested on the land, sea and air. Dept. of Defense representatives were in attendance during a recent event where two of the low-power devices, which can change beam directions in a thousandth of a second, were demonstrated in an aircraft during flight tests held in Virginia during February 2014.
First developed five years ago at Rice Univ., silicon oxide memories are a type of two-terminal, “resistive random-access memory” (RRAM) technology that beats flash memory’s data density by a factor of 50. At Rice, the laboratory of chemist and 2013 R&D Magazine Scientist of the Year James Tour has recently developed a new version of RRAM that Tour believes outperforms more than a dozen competing versions.
Police in New York City are concerned that the increasing popularity of drones in such a tightly packed metropolis could carry major risks, even becoming a potential tool for terrorists to conduct surveillance or carry out attacks. Even though it's illegal to fly the devices just about anywhere in New York City without permission, recent incidents and breathtaking videos of Manhattan suggest that the restrictions are being widely flouted.
A team in the U.K. has found that by sandwiching a 7-nm thick layer of a phase change material between two layers of a transparent electrode they could use a tiny current to “draw” images within the sandwich “stack”. The discovery could make it possible to create pixels just a few hundred nanometers across and pave the way for extremely high-resolution and low-energy thin, flexible displays.
Spin current, in which an ultra-short laser pulse generates electrons all with the same spin, is a promising new technology which potentially allows data to be stored 1,000 times as fast as traditional hard drive. Researchers in The Netherlands have recently shown that generated spin current is actually able to cause a change in magnetization, hinting at practical application in the future.
A recent study by researchers at the Univ. of Illinois at Urbana-Champaign provides new insights on the physical mechanisms governing the interplay of spin and heat at the nanoscale, and addresses the fundamental limits of ultra-fast spintronic devices for data storage and information processing.
Too cool and faint, many objects in the universe are impossible to detect with visible light. Now a Northwestern Univ. team has refined a new technology that could make these colder objects more visible, paving the way for enhanced exploration of deep space. The new technology uses a type II superlattice material called indium arsenide/indium arsenide antimonide (InAs/InAsSb).
Cell phone metadata has been in the news quite a bit lately, but the National Security Agency isn’t the only organization that collects information about people’s online behavior. Newly downloaded cell phone apps routinely ask to access your location information, your address book or other apps, and of course, Websites like Amazon or Netflix track your browsing history in the interest of making personalized recommendations.
A decade of research by Rice Univ. scientists has produced a 2-D model to prove how gas hydrate, the “ice that burns,” is formed under the ocean floor. Gas hydrate has potential as a source of abundant energy, if it can be extracted and turned into usable form. It also has potential to do great harm.
A Brown Univ. group has developed a wireless virtual reality system to study a phenomenon that scientists don’t yet understand: How pedestrians interact with each other and how those individual behaviors, in turn, generate patterns of crowd movement. The system, which uses motion capture technology can immerse up to four people in a carefully controlled, realistic virtual crowd.
Researchers in Korea have been working to perfect their two-sided, touchable, transparent display technology called TransWall. Featuring an incorporated surface transducer, TransWall provides audio and vibrotactile feedback to users, enabling people to see, hear, or even touch other people through the wall while enjoying gaming and interpersonal communication.
