Microsoft announced the biggest layoffs in its history Thursday, saying it will cut 18,000 jobs or 14 percent of its workforce as it streamlines its Nokia mobile device business to focus on using the Windows Phone operating system. Although the job cuts had been expected, the extent of them was a surprise.
Scientists in Belgium have recently fabricated the world’s first randomly deformable optical waveguide. This innovative optical link remains functional for bending radii down to 7 mm, and can be stretched to more than a third of its length. A link like this can be used to interconnect optical components within a stretchable system, just like stretchable electrical interconnections.
The doubling of transistors on a microprocessor occurs roughly every two years, and is the outcome of what is called Moore’s Law. In a bid to continue this trend of decreasing transistor size and increasing computation and energy efficiency, chip-maker Intel has partnered with Lawrence Berkeley National Laboratory to design an entirely new kind of photoresist, one that combines the best features of two existing types of resist.
Last year, Massachusetts Institute of Technology researchers discovered that when water droplets spontaneously jump away from superhydrophobic surfaces during condensation, they can gain electric charge in the process. Now, the same team has demonstrated that this process can generate small amounts of electricity that might be used to power electronic devices.
A research team in Illinois has built a new type of tunable nanoscale antenna that could facilitate optomechanical systems that actuate mechanical motion through plasmonic field enhancements.

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.
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.
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.
An international research collaboration has designed a miniscule cooling element that uses spin waves to transport heat in electrical insulators. Although physicists have used spin for cooling purposes before, this is the first time that they have successfully done this in insulating materials. The cooling element could be used to dissipate heat in the increasingly smaller electrical components of computer chips.
Robert Wolkow and his team at the Univ. of Alberta are working to engineer atomically precise computing technologies that have practical, real-world applications. In recent research, he and his team observed for the first time how an electrical current flows across the skin of a silicon crystal and also measured electrical resistance as the current moved over a single atomic step.
Computer simulation has shown Stanford Univ. engineers how to make a crystal that would toggle like a light switch between conductive and non-conductive structures. This flexible, switchable lattice, just three atoms thick, can be turned on or off by mechanically pushing or pulling, and could lead to flexible electronic materials.
An Android update, wearable gadgets, and so-called smart home devices are just some of the innovations Google is likely to show off at its two-day developer conference, which begins today in San Francisco. In recent years, the conference has focused on smartphones and tablets, but this year Google's Android operating system is expected to stretch into cars, homes, and smartwatches.
In work that unmasks some of the magic behind memristors and "resistive random access memory," or RRAM, researchers have shown that the metal particles in memristors don't stay put as previously thought. The findings have broad implications for the semiconductor industry and beyond. They show, for the first time, exactly how some memristors remember.
Rice Univ. scientists have received a grant to develop terahertz-based technology that could enable a dramatic advance in wireless communications and other disciplines. The $1 million grant by the W.M. Keck Foundation will let them tackle some of the knotty problems barring them from using the largely untapped terahertz region of the electromagnetic spectrum. Rice will supplement the grant with a $1.5 million commitment.
Several years ago, Georgia Institute of Technology researchers created a technology-enhanced glove that can teach beginners how to play piano melodies in 45 min. Now they’ve advanced the same wearable computing technology to help people learn how to read and write Braille. The twist is that people wearing the glove don’t have to pay attention. They learn while doing something else.
The more cores a computer chip has, the bigger the problem of communication between cores becomes. For years, Li-Shiuan Peh, a professor of electrical engineering and computer science at Massachusetts Institute of Technology, has argued that the massively multicore chips of the future will need to resemble little Internets, where each core has an associated router, and data travels between cores in packets of fixed size.
Your smartphone’s display glass could soon be more than just a pretty face, thanks to new technology developed by researchers from Corning Inc. The team has created the first laser-written light-guiding systems that are efficient enough to be developed for commercial use.
Organic semiconductors have tremendous potential for complementing conventional, inorganic semiconductors, but energy losses or barriers at the connection interfaces have blocked development efforts. Physicists have now implemented a detailed electrostatic model which is capable of covering the full phenomenological range of interfacial energy-level alignment regimes within a single, consistent framework.
Explosions caused by leaking gas pipes have frequently made headlines in recent years. But while the problem of old and failing pipes has garnered much attention, methods for addressing such failing infrastructure have lagged far behind. Typically, leaks are found using aboveground acoustic sensors. But these systems are very slow, and can miss small leaks altogether. Now researchers have devised a robotic system that can detect leaks.
Researchers have shown how to modify a smartphone so that it can be used to measure a person's walking gait to prevent falls in people with compromised balance, such as the elderly or those with Parkinson's disease. The innovation, being commercialized as SmartGait, is designed as a tool to aid health care officials in assessing a person's risk of falling and identifying ways to avoid injury.
Your eye could someday house its own high-tech information center, tracking important changes and letting you know when it’s time to see an eye doctor. Univ. of Washington engineers have designed a low-power sensor that could be placed permanently in a person’s eye to track hard-to-measure changes in eye pressure.
Altera Corp. of California and Lime Microsystems, a radio frequency transceiver developer in the U.K. have entered into a Strategic Cooperation Agreement focused on jointly developing and promoting programmable solutions for a diverse range of broadband wireless markets. The agreement will result in the development of optimized field programmable radio frequency (FPRF) transceivers and other digital RF solutions.
One might be hidden in a cross on a church lawn. Others are disguised as a cactus in the desert, a silo in farm country or a palm tree reaching into a sunny sky. Whatever the deception, the goal is the same: concealing the tall, slender cellphone towers that most Americans need but few want to see erected in their neighborhoods.
Referees may soon have a new way of determining whether a football team has scored a touchdown or gotten a first down. Researchers from North Carolina State Univ. and Carnegie Mellon Univ., in collaboration with Disney Research, have developed a system that can track a football in 3-D space using low-frequency magnetic fields.
Engineers at the Univ. of Arkansas have designed integrated circuits that can survive at temperatures greater than 350 C—or roughly 660 F. The team achieved the higher performance by combining silicon carbide with wide temperature design techniques.
