Computer security: 'Melbourne Shuffle' secures data in the cloud Posted: 10 Jul 2014 08:19 AM PDT Encryption might not be enough for all that data stored in the cloud. Usage patterns -- which files are accessed and when -- can give away secrets as well. Computer scientists have developed an algorithm to sweep away those digital footprints. They call it the Melbourne Shuffle.

Speeding up data storage by a thousand times with 'spin current' Posted: 10 Jul 2014 05:12 AM PDT A hard drive stores bits in the form of tiny magnetic domains. The directions of the magnetic north and south poles of these domains, which are referred to as the magnetization, determine whether they are a 0 or a 1. Data is stored by changing the direction of the magnetization of the associated bits. At present this is done using a write head to create a local magnetic field, which makes a bit change direction.
