Securing the cloud
June 10, 2013 12:00 am | by Massachusetts Institute of Technology | CommentsHomomorphic encryption is one of the most exciting new research topics in cryptography, which promises to make cloud computing perfectly secure. With it, a Web user would send encrypted data to a server in the cloud, which would process it without decrypting it and send back a still-encrypted result. Sometimes, however, the server needs to know something about the data it’s handling. Otherwise, some computational tasks become prohibit...

Is Big Data turning government into 'Big Brother?'
June 7, 2013 3:08 am | by MICHAEL LIEDTKE - AP Technology Writer - Associated Press | CommentsThe revelations that the National Security Agency is perusing millions of U.S. customer phone records at Verizon Communications and snooping on the digital communications stored by nine major Internet services illustrate how aggressively personal data is being collected and analyzed.
Promising material for lithium-ion batteries
June 6, 2013 3:26 pm | by Technische Universitaet Muenchen | CommentsSo far, the negative electrode typically consists of graphite, whose layers can store lithium atoms. Scientists at the Technische Universitaet Muenchen (TUM) have now developed a material made of boron and silicon that could smooth the way to systems with higher capacities.
Study suggests second life for possible spintronic materials
June 6, 2013 3:16 pm | by EurekAlert! | CommentsTen years ago, scientists were convinced that a combination of manganese and gallium nitride could be a key material to create spintronics, the next generation of electronic devices that operate on properties found at the nanoscale. But researchers grew discouraged when experiments indicated that the two materials were as harmonious as oil and water.
