Applied physicists at the Harvard School of Engineering and Applied Sciences (SEAS) have created an ultrathin, flat lens that focuses light without imparting the distortions of conventional lenses. Left to right : Francesco Aieta, Federico Capasso, and Patrice Genevet. At a mere 60 nanometers thick, the flat lens is essentially two-dimensional, yet its focusing power approaches the ultimate physical limit set by the laws of diffraction.
Google and Boingo are building on their free Wi-Fi project in New York City , launching the advertising-paid access model in eight malls across the country. Though the project is still in its infancy, it represents a growing trend to make Wi-Fi a free and readily accessible resource, while depending on ad views to pay the bill.
PayPal is confirming reports that it is test-running a new app-based checkout system in McDonald’s restaurants, a pilot program that could push the online payment broker - and the notion of phone-based payments - much further into the consumer shopping experience. It could also add confusing choices and tools to manage in an increasinly fragmented payment landscape.
If Doctor Evil ever lowered his lofty goal of sharks with frickin’ laser beams on their heads to something more manageable, such as lasers on frickin’ tadpoles, the world’s smallest laser might serve him well. Physicists from the University of Texas at Austin working with colleagues in Taiwan and China have created what they claim to be the world’s smallest laser.
I’ve got a riddle for you. What do Blu-ray disks, military radars and LED light bulbs have in common? Chances are, if you work outside of the defense or electronics sectors, you may not easily make the connection. But the common thread is a little-known technology called Gallium Nitride (GaN for short).
The firm's disruptive gallium nitride technology is to be developed for LEDs, laser diodes, and power electronics Soraa, a developer of GaN on GaN solid-state lighting technology, has been selected by Advanced Research Projects Agency-Energy (ARPA-E) to lead a project on the development of bulk GaN substrates.
National Central University (NCU) in Taiwan will use an AIXTRON metal-organic chemical vapor deposition (MOCVD) system to research gallium-nitride-on-silicon (GaN-on-Si) power semiconductors . An existing AIXTRON customer, NCU installed a 1 x 6” AIXTRON Close Coupled Showerhead MOCVD system. They will grow GaN epitaxial structures on 6” silicon substrates, which will be used in R&D of power management devices.

Researchers have developed a self-charging power cell that directly converts mechanical energy to chemical energy, storing the power until it is released as electrical current. By eliminating the need to convert mechanical energy to electrical energy for charging a battery, the new hybrid generator-storage cell utilizes mechanical energy more efficiently than systems using separate generators and batteries.
Whether a material conducts electricity without losses is not least a question of the right temperature. In future it may be possible to make a more reliable prediction for high-temperature superconductors. These materials lose their resistance if they are cooled with liquid nitrogen, which is relatively easy to handle.
Realization of a new type of magnetic phase in devices opens the door to electronics based on topologically non-trivial materials A team of researchers at RIKEN and the University of Tokyo has demonstrated a new material that promises to eliminate loss in electrical power transmission. The surprise is that their methodology for solving this classic energy problem is based upon the first realization of a highly exotic type of magnetic semiconductor first theorized less than a decade ago - a magnetic topological insulator.
Research by Nosang Myung , a professor at the University of California, Riverside, Bourns College of Engineering , has enabled a Riverside company to develop an “electronic nose” prototype that can detect small quantities of harmful airborne substances. Nano Engineered Applications, Inc. , an Innovation Economy Corporation company, has completed the prototype which is based on intellectual property exclusively licensed from the University of California.
Mobile-phone owners are not just spending money on their phones and monthly subscriptions. Sales of mobile-phone accessories shot up 32 percent during the first half of 2012 compared with the same period last year, says a new report from NPD Group. Cases proved the most popular accessory, with sales soaring 70 percent over 2011 despite an average 25 percent increase in case prices.
Everyone complains about email. We’re awash in the stuff. We feel inundated. Overwhelmed. Out of control. Lately there’s been quite a lot of talk about what to do about it. Jordan Cook hates it , MG Siegler tried to quit it , and Alan Henry argues you can’t . People want Gmail to speed up , Yahoo! to catch up , or, someone, anyone, to make something better .
NASA's new robotic lander, the Mighty Eagle When NASA's Mars rover Curiosity began its entry, descent and landing sequence two weeks ago, the success of the mission hinged on what was known as the " 7 minutes of terror " -- a period during which NASA was out of touch with the vehicle, relying on its autonomous landing sequence to successfully touch down on the surface.
A meal isn't a meal without a cell phone. You need to photograph the food and get it onto your Twitter feed, before any of the other diners does the same. It isn't called A Twitter "feed" for nothing, you know. You need to be able to Google "the collected works of Al Green," just in case there's a dispute about who wrote "Let's Stay Together.
Armed with a little more than a hose and high-speed video equipment, researchers have cracked one of science’s wettest problems. As dog-owners know all too well, when their canine companions take a dip in a pond this is swiftly followed by a twisting shake-down that involves an ecstasy of flopping ears and flapping jowls.
Manage lights, TV, refrigerators and more through your phone or tablet when the latest wireless technology rolls into all your home devices Wireless technologies have been transforming domestic life since the availability of home radios in the 1920s. Since then every new kind of wireless technology and every new application has brought more transformative changes to the home.
IBC announces that the IBC2012 Best Conference Paper has been awarded to a group of researchers from the Fraunhofer Institute for Telecommunications Heinrich Hertz Institute. Their paper looks at a critical issue for broadcasters who want to move 3D television into the mainstream: the ability to create the signals for glasses-free 3D displays from two-camera stereoscopic origination.
Not only does your phone know where you are, but it knows where you are going to be. It may even know why you're going there. He calls it the "Interdependence and Predictability of Human Mobility and Social Interactions," but the algorithm researcher Mirco Musolesi and his team recently tested in the UK stirs up thoughts reminiscent of Phillip K.
The system, known as Merchant Customer Exchange, is a retailer-led initiative that would match similar services from Google Inc, which began operating its own system last year on its Android devices. The group of retailers, which accounts for about $1 trillion in annual sales, wants to make sure it has a say as standards for mobile payments are developed, said Terry Scully, Target's president of financial and retail services.
Research in Motion CEO Thorsten Heins said the company is planning to take its new BlackBerry 10 smartphones on a road show to woo carriers, developers and ultimately consumers. In two separate interviews with CNET News' Roger Cheng and ZDNet, Heins outlined RIM's product cadence, roughly six new devices and smartphones that look and feel better than previous efforts.
Slides prepared by startup Modern Meadow pitch 3D-printed meat as a more environmentally friendly approach to dinner. 3D printing has been used to create running shoes , medical implants , and, to the delight of firearm enthusiasts, a .22 caliber handgun .
