Scientists at the Vienna University of Technology have now managed to combine a graphene photodetector with a standard silicon chip. It can transform light of all important frequencies used in telecommunications into electrical signals. The scientific results have now been published in the journal “Nature Photonics”.
Google has acquired Bump, the maker of a smartphone app that allows users to share files by bumping devices together. The two companies did not release financial terms of the deal. In a blog post announcing the acquisition Monday, Bump CEO David Lieb said the company's apps, which also include a photo sharing service, Flock, will keep working for now.
Using premier beams of ultraviolet light at the ALS, a DOE national user facility for synchrotron radiation, the collaboration has reported the first demonstration of high-temperature superconductivity in the surface of a topological insulator – a unique class of advanced materials that are electrically insulating on the inside but conducting on the surface.
In the latest issue of Nature Photonics, researchers at MIT, Columbia University and IBM’s T. J. Watson Research Center describe a promising new application of graphene, in the photodetectors that would convert optical signals to electrical signals in integrated optoelectronic computer chips.
In today's computers, moving data to and from main memory consumes so much time and energy that microprocessors have their own small, high-speed memory banks, known as "caches," which store frequently used data. Traditionally, managing the caches has required fairly simple algorithms that can be hard-wired into the chips.
A daring attempt to graft a rogue piece of hardware onto a computer at a London branch of Spanish bank Santander could have drained millions from its coffers, police said Friday, an indication of the potential for electronic crime to tear huge chunks off financial institutions' balance sheets.
When Twitter started seven years ago as an obscure medium for geeks, critics dismissed it as an exercise in narcissism. Some thought it would be as intriguing as watching people gaze at their bellybuttons. But it quickly matured into a worldwide messaging service used by everyone from heads of state to revolutionaries to companies trying to hawk products.
A new, environmentally-friendly electronic alloy consisting of 50 aluminum atoms bound to 50 atoms of antimony may be promising for building next-generation "phase-change" memory devices, which may be the data-storage technology of the future, according to a new paper published in the journal Applied Physics Letters, which is produced by AIP Publishing.

With love as its starting point, a new startup, BeLuvv has combined wearable devices with software applications and created Guardian, the world’s first wearable designed specifically for children and their safety. Featuring replaceable outer cases, Guardian wearables come in vibrant colors to match children’s clothing. Not only does Guardian represent milestone in children’s safety, it is also a fashion statement.
NASA's Voyager 1 probe has left the solar system, boldly going where no machine has gone before. Thirty-six years after it rocketed away from Earth, the plutonium-powered spacecraft has escaped the sun's influence and is now cruising 11 1/2 billion miles away in interstellar space, or the vast, cold emptiness between the stars, NASA said Thursday.
witter, the short messaging service named after chirping birds, is finally ready to migrate to Wall Street. Fittingly enough, the company resorted to a tweet to titillate its more than 200 million users and a flock of potential investors with its long-awaited plans to pursue an initial public offering of stock.
The Federal Trade Commission is looking into a set of policy changes that Facebook proposed in late August, though the agency says it's part of a routine monitoring of the company's privacy practices. The changes, which have not yet gone into effect, have drawn criticism from privacy groups concerned about how the world's largest online social network uses its members' photos and other information in advertisements.
Under the terms of the agreement, America II will stock and distribute America Semiconductor’s extensive offering of high-power standard, fast and super-fast recovery rectifiers, bridge rectifiers, and low-power semiconductors throughout the U.S., Europe and Asia, with an emphasis on US markets. Additionally covered in the agreement are America Semiconductor’s innovative portfolio of discrete semiconductor parts.
Lantronix announced a marketing and sales partnership with Wyless -- a global M2M wireless connectivity solution provider -- to provide customers with a bundled 3.5G wireless solution.
New FCI Video Explains Maintenance Cost Advantages Of VeriCal In-Situ Calibration with ST100 Flow MeterSeptember 12, 2013 2:55 pm | by Fluid Components International | News | Comments
A video from Fluid Components International illustrates the VeriCal In-Situ Calibration System for the ST100 Series Flow Meter, which enables periodic field validation and verification of a flow meter’s measuring performance without extracting the meter from the pipe or process.
Zain Jordan recently announced that it has selected the Ericsson Charging & Billing in One (CBIO) solution as part of the operator’s ongoing efforts to provide subscribers with additional billing flexibility. This marks a success story with Zain in Jordan to implement Ericsson’s single rating convergence and swapping out five different rating engines.
According to a consumer survey conducted by Usurv immediately after news of the product was released on Monday, 31 percent of existing UK iPhone users say they want the new Apple iPhone 5S. The survey results indicate a drop in enthusiasm for the Apple phone brand since last year, when a similar survey (conducted after the iPhone 5 launch) showed that 44 percent of iPhone users were willing to upgrade straight away.
The Allworld Exhibitions Alliance, whose Asian event experience includes CommunicAsia show in Singapore, is to stage the first ever major telecoms event in Myanmar – providing a showcase for one the world’s largest undeveloped markets to play host to the international telecoms industry.
DfR Solutions announced that the U.S. Department of State, Directorate of Defense Trade Controls (DDTC) has approved its International Traffic in Arms Regulations (ITAR) registration. The U.S. Government requires all manufacturers, exporters, and brokers of defense articles, defense services, or related technical data to be ITAR registered and fully compliant.

Months after he was born, in 1948, Ron McCallum became blind. In this charming, moving talk, he shows how he is able to read -- and celebrates the progression of clever tools and adaptive computer technologies that make it possible. With their help, and that of generous volunteers, he's become a lawyer, an academic, and, most of all, a voracious reader.
AT&T and some other companies learned quickly on Wednesday, the 12th anniversary of the Sept. 11 attacks, that it's sometimes best to stay out of the conversation. Even if everyone else is talking. Twitter was aflutter with American flags, bald eagles, and photos of the New York City skyline on Wednesday, and the hashtag "neverforget" was one of the top trends on the microblogging site all day.
Former Deutsche Bank chief Josef Ackermann said Thursday he was stepping down from the board of Siemens AG following an argument over the appointment of a new CEO at the German industrial conglomerate. The announcement at an event in Berlin came less than a month after Ackermann resigned as chairman of Switzerland's Zurich Insurance Group days over the suicide of its finance chief.
Last year, eager buyers in Beijing waited overnight in freezing weather to buy the iPhone 4S. Pressure to get it — and the profit to be made by reselling scarce phones — prompted some to pelt the store with eggs when Apple, worried about the size of the crowd, postponed opening.
