New optical materials could serve as the nuts and bolts of future ...
This year’s Submarine Cable Map pays tribute to pioneering mapmakers of the Age of Discovery, incorporating elements of medieval and renaissance cartography. In addition to serving as navigational aids, maps from this era were works of art, often adorned with fanciful illustrations of real and imagined dangers. TeleGeography’s 2015 map brings back the lost design aesthetic to provide a view of the network through the lens of a bygone era.

A team of Columbia Engineering researchers has invented a technology — full-duplex radio integrated circuits (ICs) — that can be implemented in nanoscale CMOS to enable simultaneous transmission and reception at the same frequency in a wireless radio. Up to now, this has been thought to be impossible: transmitters and receivers either work at different times, or at the same time but at different frequencies.
Users of an e-mail service backed by the German government will soon be able to rely on strong encryption of the kind that used to be the preserve of geeks and hackers, officials said on March 9, 2015. From April onward De-Mail, an e-mail service available to anyone in Germany, will feature end-to-end encryption based on the Pretty Good Privacy system.

Sci-fi solutions or making friends one at a time? Google and Facebook are taking different routes to expanding Internet use and access among the unconnected in developing countries. The two Internet giants gave updates on their efforts — and differing approaches — at the Mobile World Congress wireless show in Barcelona on March 2, 2015.
Hypertext Transfer Protocol, HTTP, is a key component of the World Wide Web. It is the communications layer through which Web browsers request Web pages from Web servers and with which Web servers respond with the contents of the page. Like much of the internet it’s been around for decades, but a recent announcement reveals that HTTP/2, the first major update in 15 years, is about to arrive.
Cyberspace is the new "Wild West," President Barack Obama said, with everyone looking to the government to be the sheriff. But he told the private sector it must do more to stop cyber attacks aimed at the U.S. every day. Obama signed an executive order aimed at making it easier for private firms to have access to classified information about cyber attacks.
Connecting different kinds of devices, not just computers and communications devices, to the Internet could lead to new ways of working with a wide range of machinery, sensors, domestic and other appliances. Researchers suggest that we are on the verge of another technological revolution, but practicalities and legal obstacles may stymie the development of the so-called Internet of Things (IoT) if they are not addressed quickly.
A new way to process fiber optic signals has been demonstrated, which could double the distance at which data travels error-free through transatlantic sub-marine cables. The new method has the potential to reduce the costs of long-distance optical fiber communications, as signals wouldn’t need to be electronically boosted on their journey, which is important when the cables are buried underground or at the bottom of the ocean.
Much of our reams of data sits in large databases of unstructured text. Finding insights among e-mails, text documents and Web sites is extremely difficult, unless we can search, characterize and classify their text data in a meaningful way. A leading big data algorithm for finding related topics within unstructured text is LDA. But Luis Amaral found that it was neither as accurate nor reproducible as a leading topic modeling algorithm ...
IBM researchers have announced a cloud-based technology that holds potential to help consumers better protect online personal data, including date of birth, home address and credit card numbers. The technology, called Identity Mixer, uses a cryptographic algorithm to encrypt the certified identity attributes of a user in a way that allows the user to reveal only selected pieces to third parties.
Charles H. Townes' inspiration for the predecessor of the laser came to him while sitting on a park bench, waiting for a restaurant to open for breakfast. On the tranquil morning of April 26, 1951, Townes scribbled a theory on scrap paper that would lead to the laser, the invention he's known for and which transformed everyday life and led to other scientific discoveries. The 99-year-old Nobel Prize-winning physicist died January 27, 2015.
Researchers have demonstrated that the 1935 Einstein-Podolsky-Rosen quantum mechanics paradox may be extended to more than two optical systems, paving the way for exploration of larger quantum networks. The experiment also identified properties that may be useful in establishing secure quantum communication networks where shared sequences of numbers created between two parties need to be kept secret from a third party.
