New Record Set for Data-Transfer Speeds

New Record Set for Data-Transfer Speeds

Researchers at IBM have set a new record for data transmission over a multimode optical fiber, a type of cable that is typically used to connect nearby computers within a single building or on a campus. The achievement demonstrated that the standard, existing technology for sending data over short distances should be able to meet […]

How Remote Places Can Get Cellular Coverage by Doing It Themselves

How Remote Places Can Get Cellular Coverage by Doing It Themselves

With Swedish telephone numbers and a tree-bound base station, a remote Indonesian village runs its own telecommunications company.   A four-hour drive from the nearest cellular coverage in the remote highlands of Papua, Indonesia, a new kind of guerilla telecom network is operating, albeit outside the law, using a cheap base station roped into a […]

World Record: Wireless Data Transmission at 100 Gbit/S

World Record: Wireless Data Transmission at 100 Gbit/S

Extension of cable-based telecommunication networks requires high investments in both conurbations and rural areas. Broadband data transmission via radio relay links might help to cross rivers, motorways or nature protection areas at strategic node points, and to make network extension economically feasible. In the current issue of the nature photonics magazine, researchers present a method […]

Magnetic Nanowires: Domain Walls as New Information Storage Medium

Magnetic Nanowires: Domain Walls as New Information Storage Medium

While searching for ever smaller devices that can be used as data storage systems and novel sensors, physicists at Johannes Gutenberg University Mainz (JGU) have directly observed magnetization dynamics processes in magnetic nanowires and thus paved the way for further research in the field of nanomagnetism. Small magnetic domain wall structures in nanowires can be […]

Digital Streak Camera Captures Full-Color Photographs of High-Speed Objects

Digital Streak Camera Captures Full-Color Photographs of High-Speed Objects

Researchers at MetroLaser, Inc., have developed a new design for a digital streak camera that captures full-color images of projectiles traveling up to 3350 m/s, which is 10 times the speed of sound. This system was designed to replace the outdated film-based streak cameras that are still in use at high-speed test tracks.   Film-based […]

Eye-Tracking Could Outshine Passwords If Made User-Friendly

Eye-Tracking Could Outshine Passwords If Made User-Friendly

It’s a wonder we still put up with passwords.   We forget our highly secretive combinations, so we frequently have them reset and sent to our cellphones and alternative email addresses. We come up with clever jumbles of letters and words, only to mess up the order. We sit there on the login screen, desperately […]

Writing Computer Programs Using Ordinary Language: Systems Convert Ordinary Language to Code

Writing Computer Programs Using Ordinary Language: Systems Convert Ordinary Language to Code

In a pair of recent papers, researchers at MIT’s Computer Science and Artificial Intelligence Laboratory have demonstrated that, for a few specific tasks, it’s possible to write computer programs using ordinary language rather than special-purpose programming languages.   The work may be of some help to programmers, and it could let nonprogrammers manipulate common types […]

5-D Optical Memory in Glass Could Record the Last Evidence of Civilization

5-D Optical Memory in Glass Could Record the Last Evidence of Civilization

Using nanostructured glass, scientists at the University of Southampton have, for the first time, experimentally demonstrated the recording and retrieval processes of five dimensional digital data by femtosecond laser writing. The storage allows unprecedented parameters including 360 TB/disc data capacity, thermal stability up to 1000°C and practically unlimited lifetime.   Coined as the ‘Superman’ memory […]

Breakthrough in Internet Bandwidth: New Fiber Optic Technology Could Ease Internet Congestion, Video Streaming

Breakthrough in Internet Bandwidth: New Fiber Optic Technology Could Ease Internet Congestion, Video Streaming

As rapidly increasing demand for bandwidth strains the Internet’s capacity, a team of engineers has devised a new fiber optic technology that promises to increase bandwidth dramatically. The new technology could enable Internet providers to offer much greater connectivity — from decreased network congestion to on-demand video streaming.   Described in the June 28 issue […]

Cities Are a New Kind of Complex System: Part Social Reactor, Part Network

Cities Are a New Kind of Complex System: Part Social Reactor, Part Network

Cities have long been likened to organisms, ant colonies, and river networks. But these and other analogies fail to capture the essence of how cities really function.   New research by Santa Fe Institute Professor Luis Bettencourt suggests a city is something new in nature — a sort of social reactor that is part star […]
