Computer Security: ‘Melbourne Shuffle’ Secures Data in the Cloud

  To keep data safe in the cloud, a group of computer scientists suggests doing the Melbourne Shuffle. That may sound like a dance move (and it is), but it’s also a computer algorithm developed by researchers at Brown University. The computing version of the Melbourne Shuffle aims to hide patterns that may emerge as [...]

Future Electronics: Super-Efficient Hard Drives

Future Electronics: Super-Efficient Hard Drives

Researchers from ETH Zurich and the Paul Scherrer Institute PSI demonstrate how the magnetic structure can be altered quickly in novel materials. The effect could be used in efficient hard drives of the future.   Data on a hard drive is stored by flipping small magnetic domains. Researchers from the Paul Scherrer Institute PSI and [...]

Magnet for Fast and Cheap Data Storage

Magnet for Fast and Cheap Data Storage

Professor Rasing, physicist at Radboud University Nijmegen, came up with a new synthetic material for optical data storage.   Optical data storage does not require expensive magnetic materials as synthetic alternatives work just as well. This is the finding of an international team from York, Berlin and Nijmegen, published Thursday February 27 in Applied Physics [...]

New Record Set for Data-Transfer Speeds

New Record Set for Data-Transfer Speeds

Researchers at IBM have set a new record for data transmission over a multimode optical fiber, a type of cable that is typically used to connect nearby computers within a single building or on a campus. The achievement demonstrated that the standard, existing technology for sending data over short distances should be able to meet [...]

Smarter Caching, Better Chip Performance

Smarter Caching, Better Chip Performance

Cleverer management of the local memory banks known as ‘caches’ could improve computer chips’ performance while reducing their energy consumption.   Computer chips keep getting faster because transistors keep getting smaller. But the chips themselves are as big as ever, so data moving around the chip, and between chips and main memory, has to travel [...]
