Engineers and physicists at Harvard University have managed to capture light in tiny diamond pillars embedded in silver, releasing a stream of single photons at a controllable rate. The advance represents a milestone on the road to quantum networks in which information can be encoded in spins of electrons and carried through a network via light, one photon at a time.
From the moment he saw Steve Wozniak’s homebuilt computer a pattern was set for Steve Jobs’ career. He moved technology from garages to pockets, took entertainment from discs to bytes and turned gadgets into extensions of the people who use them.
Researchers from North Carolina State University and IBM have developed a new, experimental technique to better protect sensitive information in cloud computing—without significantly affecting the system’s overall performance.
Using millions of Twitter subscribers as living "sensors," engineers from Rice University and Motorola Mobility have found a way to monitor fans’ levels of excitement and to keep track of the action in National Football League (NFL) games, without ever switching on a TV.
Rice University physicists have created a tiny "electron superhighway" that could one day be useful for building a quantum computer. The physicists described a new method for making a tiny device called a "quantum spin Hall topological insulator", which is one of the building blocks needed to create quantum particles that store and manipulate data.
The U.S.- and Singapore-based creators of the low-cost I-slate electronic tablet are preparing for full-scale production now that a yearlong series of tests has shown that the device is an effective learning tool for Indian children.
Imaging sensor chips that form the heart of built-in cameras helped engineers at the California Institute of Technology create a "smart" petri dish. The ePetri is a compact, lens-free microscopy imaging platform that does away with the need for bulky microscopes and significantly reduces labor for the researcher.
With a net profit last year was more than five times the combined earnings of five Japanese rivals, including Toshiba, Hitachi, and Sony, Samsung is a surging electronics giant. But the company, despite a reputation for high quality, is still perceived as a follower and has yet to mesmerize customers.
Molecular motion in proteins comes in three distinct classes, according to a collaboration by researchers at Oak Ridge National Laboratory and the University of Tennessee. The research team combined high-performance computer simulation with neutron scattering experiments to understand atomic-level motions that underpin the operations of proteins.
Since 2000, R&D Magazine has annually honored an individual whose research has greatly contributed to the advance of high technology, and whose achievements have helped change society. In 2011, for the first time, the editors recognize the teamwork involved in making possible the most advanced computer-supported intelligence system yet: Watson.
Researchers are developing a new type of computer memory that could be faster than the existing commercial memory and use far less power than flash memory devices. The technology combines silicon nanowires with a "ferroelectric" polymer, a material that switches polarity when electric fields are applied, making possible a new type of ferroelectric transistor.
University of Texas at Austin researchers have discovered how to extract and use information in an individual image to determine how far objects are from the focus distance, a feat only accomplished by human and animal visual systems until now.
A top Samsung executive says the company will take a bolder stance in its patent battle with smartphone and tablet rival Apple, which Samsung claims has been "free riding" on its patented wireless technologies.
Physicists in Germany, working in collaboration with researchers from Grenoble and Tokyo, were able to define two quantum dots, occupied with electrons, in a semiconductor, select a single electron from one of them using a sound wave, and then to transport it to the neighbouring quantum dot. The breakthrough may help achieve complex qubits.
Researchers from Cambridge University's Cavendish Laboratory have moved an individual electron along a wire, batting it back and forth over 60 times, rather like the ball in a game of ping-pong. The technique helps retain coherence, and could be beneficial in the development of quantum computing.
Multiscale complexity is common across all combustion applications—internal combustion engines, rockets, and industrial boilers—and can range from tens of meters to billionths of meters. New techniques being employed at supercomputers covers this huge scale range using fewer computer hours, and could benefit efficiency levels in the combustion industry.
The U.S. Department of Energy's National Renewable Energy Laboratory (NREL) has earned a 2011 Platinum-level Award from the Federal Electronics Challenge (FEC) recognizing NREL's efforts to help the federal government improve its sustainable practices.
Researchers from the Massachusetts Institute of Technology have developed a sophisticated computer model of a corporate information infrastructure, which could help IT managers predict the effects of changes to their networks. In a study funded by Ford Motor Co., the researchers compared their model’s predictions to data supplied by Ford and found that, on average, its estimates of response times for queries sent to company servers were within 5 to 13% of the real times.
NIST has published two new documents on cloud computing: the first edition of a cloud computing standards roadmap and a cloud computing reference architecture and taxonomy. Together, the documents provide guidance to help understand cloud computing standards and categories of cloud services that can be used government-wide.
An Oak Ridge National Laboratory invention able to quickly predict 3D structure of protein could have huge implications for drug discovery and human health. While scientists have long studied protein structure and the mechanism of folding, this marks the first time they are able to computationally predict 3D structure independent of size of the protein.
Enough with the fun and games. Watson is going to work. IBM's supercomputer system, best known for trouncing the world's best "Jeopardy!" players on TV, is being tapped by one of the nation's largest health insurers to help diagnose medical problems and authorize treatments.
Engineers at the University of California, Berkeley, have shown that it is possible to reduce the minimum voltage necessary to store charge in a capacitor, an achievement that could reduce the power draw and heat generation of today's electronics.
Researchers at the Massachusetts Institute of Technology and Harvard University describe an experiment that allows a single photon to control the quantum state of another photon. The result could have wide-ranging consequences for quantum computing and quantum communication, the quantum analog to conventional telecommunications.
Massachusetts Institute of Technology researchers have created a new Urban Network Analysis (UNA) toolbox that enables urban designers and planners to describe the spatial patterns of cities using mathematical network analysis methods. Such tools can support better informed and more resilient urban design and planning in a context of rapid urbanization.
University of California, Santa Barbara physicists have demonstrated a quantum integrated circuit that implements the quantum von Neumann architecture. In this architecture, a long-lived quantum random access memory can be programmed using a quantum central processing unit, all constructed on a single chip, providing the key components for a quantum version of a classical computer.
