Eighteen months in the works, the top-secret project was announced Saturday in New Zealand, where up to 50 volunteer households are already beginning to receive the Internet briefly on their home computers via translucent helium balloons that sail by on the wind 12 miles above Earth. Google is launching these Internet-beaming antennas into the stratosphere aboard giant, jellyfish-shaped balloons.
To handle large amounts of data from detailed brain models, IBM, EPFL, and ETH Zürich are collaborating on a new hybrid memory strategy for supercomputers. They are exploring how to combine different types of memory—DRAM, which is standard for computer memory, and flash memory that is akin to USB sticks—for less expensive supercomputing performance to help advance the Human Brain Project.
Hours spent at the video gaming console not only train a player's hands to work the buttons on the controller, they probably also train the brain to make better and faster use of visual input, according to Duke Univ. researchers.
After years of quiet and largely unsuccessful diplomacy, the U.S. has brought its persistent computer-hacking problems with China into the open, delivering a steady drumbeat of reports accusing Beijing's government and military of computer-based attacks against America. Officials say the new strategy may be having some impact.
Forget to turn off the lights before leaving the apartment? No problem. Just raise your hand, finger-swipe the air, and your lights will power down. Using the common Wi-Fi signals generated by a commercial router, University of Washington computer scientists have developed gesture-recognition technology that brings this a step closer to reality.
A decade ago, the mere idea of cloud computing was a difficult concept to explain, let alone sell. Today, the technology is spurring a high-stakes scramble to buy some of the early leaders in the cloud-computing movement. The latest examples of the trend emerged Tuesday as two major technology companies announced acquisitions aimed at seeding their own clouds.
Once a science-fiction fantasy, three-dimensional printers are popping up everywhere from the desks of home hobbyists to Air Force drone research centers. The machines, generally the size of a microwave oven and costing $400 to more than $500,000, extrude layer upon layer of materials to create 3-D objects with moving parts. But experts warn this cool innovation could soon turn controversial.
Once uncommunicative industrial robots and machine tools are now beginning to talk turkey, thanks to a prototype application developed by a team of partner companies led by the National Center for Defense Manufacturing and Machining (NCDMM). This application was successfully demonstrated and tested by manufacturing researchers at NIST.
The University of Chicago has recently launched the first secure cloud-based computing system that enables researchers to access and analyze human genomic cancer information, such as the The Cancer Genome Atlas, without the costly and cumbersome infrastructure normally needed to download and store massive amounts of data.
Something unique is happening in Fremont, California, a nondescript suburb of 217,000 tucked in the high-tech region between San Francisco and Silicon Valley: manufacturing. From Tesla Motors, making cutting-edge cars, to Solaria, making solar panels, manufacturers are drawn to Fremont by incentives including a five-year waiver on business taxes, an expedited regulatory process, proximity to Silicon Valley firms and a skilled labor force.
A research team in Europe has created a new keyboard called KALQ that enables faster thumb-typing on touchscreen devices.
