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.
Big Websites usually maintain their own “data centers,” banks of tens or even hundreds of thousands of servers, all passing data back and forth to field users’ requests. Like any big, decentralized network, data centers are prone to congestion: Packets of data arriving at the same router at the same time are put in a queue, and if the queues get too long, packets can be delayed.
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.
NIST has issued for public review and comment a draft report summarizing 65 challenges that cloud computing poses to forensics investigators who uncover, gather, examine and interpret digital evidence to help solve crimes. The report was prepared by the NIST Cloud Computing Forensic Science Working Group, an international body of cloud and digital forensic experts from industry, government and academia.
Researchers at RIKEN in Japan, in collaboration with researchers from Purdue Univ., have recently demonstrated the scalability of quantum dot architectures by trapping and controlling four electrons in a single device. Circuits based on quantum dots are one of the most promising practical routes to harnessing the potential of quantum computing.
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.
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.
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.
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.
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.
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 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.
Scientists at the Massachusetts Institute of Technology are developing an audio reading device to be worn on the index finger of people whose vision is impaired, giving them affordable and immediate access to printed words. The so-called FingerReader, a prototype produced by a 3-D printer, fits like a ring on the user's finger, and is equipped with a small camera that scans text.
Fully automated "deep learning" by computers greatly improves the odds of discovering particles such as the Higgs boson, according to a recent study. In fact, this approach beats even veteran physicists' abilities, which now consists of developing mathematical formulas by hand to apply to data. New machine learning methods are rendering that approach unnecessary.
A relic from long before the age of supercomputers, the 169-year-old math strategy called the Jacobi iterative method is widely dismissed today as too slow to be useful. But thanks to a Johns Hopkins Univ. engineering student and his professor, it may soon get a new lease on life. With just a few modern-day tweaks, the researchers say they’ve made the rarely used Jacobi method work up to 200 times faster.
Aerospace engineers from the Univ. of Illinois, Urbana-Champaign are using the National Science Foundation-supported Stampede supercomputer to explore how jets in general, like those on modern aircraft and inside the human body, generate noise. This is important because no simple explanation of how jets generate noise is currently available, and without this understanding making jets quieter is difficult.
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.
Executive functions in your brain are important for making decisions in everyday life when you have to deal with sudden changes in your environment. A recent study by scientists in Singapore showed that adults who played the physics-based puzzle video game Cut the Rope regularly, for as little as an hour a day, had improved executive functions. This marks the first time video games have been shown to deliver such broad improvements.
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.
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.
