| Your next Angry Birds opponent could be a robot Posted: 10 Jul 2014 12:17 PM PDT With the help of a smart tablet and Angry Birds, children can now do something typically reserved for engineers and computer scientists: program a robot to learn new skills. The project is designed to serve as a rehabilitation tool and to help kids with disabilities.  |
| Powerful new source of up-to-date information on economic activity Posted: 10 Jul 2014 11:15 AM PDT Researchers have developed a new data infrastructure for measuring economic activity. The infrastructure uses aggregated and de-identified data on transactions and account balances from Check, a mobile payments app, to produce accurate and comprehensive measures of consumers' spending and income on a daily basis.  |
| Posted: 10 Jul 2014 10:10 AM PDT A breakthrough silicon oxide technology for high-density, next-generation computer memory is one step closer to mass production, thanks to a refinement that will allow manufacturers to fabricate devices at room temperature with conventional production methods.  |
| 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.  |
