Using sensors to make video games immersive is the industry's latest big idea
(PhysOrg.com) -- A new way to hide your secrets has been created, which is good news for both the spies and the generally duplicitous regular people of the world. This new system, instead of relying on traditional methods of hiding data such as encryption to scramble the text, hides information in an entirely different way. The newest thing in covert operations it to manipulate the location of data fragments. Essentially, the data is still being scrambled, but it is in an entirely different way.
(PhysOrg.com) -- Cambridge researchers have created a website that combines the Facebook profiles of fans of companies and public figures with personality testing to create what they are describing as a revolutionary new marketing tool.
The exponentially increasing amount of digital information, along with new challenges in storing valuable data and massive datasets, are changing the architecture of today's newest supercomputers as well as how researchers will use them to accelerate scientific discovery, said Michael Norman, director of the San Diego Supercomputer Center (SDSC) at the University of California, San Diego (UCSD).
Researchers at Carnegie Mellon University's Robotics Institute have leveraged the latest browser technology to create GigaPan Time Machine, a system that enables viewers to explore gigapixel-scale, high-resolution videos and image sequences by panning or zooming in and out of the images while simultaneously moving back and forth through time.

In a chaotic process, it is made completely unreadable. The process can be reversed with an easily remembered password, however. © Sergej Flach / MPI for the Physics of Complex Systems
