Supercomputing helps endangered species

A team including researchers from the U.S. Geological Survey (USGS) and the San Diego Zoo Institute for Conservation Research has developed a novel methodology that, for the first time, combines 3-D and advanced range estimator technologies to provide highly detailed data on the range and movements of terrestrial, aquatic, and avian wildlife species. One aspect of the study focused on...

RIKEN connects the dots for quantum supercomputing

RIKEN connects the dots for quantum supercomputing

Arrays of electrons trapped in nanoscale circuitry could form the basis for future scalable quantum supercomputers A single electron trapped in a semiconductor nanostructure can form the most basic of building blocks for a quantum supercomputer. Before practical quantum supercomputers can be realized, however, scientists need to develop a scalable architecture that allows full control over individual electrons in computational...

NASA finds friction from tides could help distant earths survive, and thrive

NASA finds friction from tides could help distant earths survive, and thrive

As anybody who has started a campfire by rubbing sticks knows, friction generates heat. Now, supercomputer modeling by NASA scientists shows that friction could be the key to survival for some distant Earth-sized planets traveling in dangerous orbits. The findings are consistent with observations that Earth-sized planets appear to be very common in other star systems. Although heat can be...

Researchers harness a powerful new source of up-to-date information on economic activity

Researchers at the University of Michigan, University of California Berkeley, and Arizona State University 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. In a paper...

Illinois study advances limits for ultrafast nano-devices

A recent study by researchers at the University of Illinois at Urbana-Champaign provides new insights on the physical mechanisms governing the interplay of spin and heat at the nanoscale, and addresses the fundamental limits of ultrafast spintronic devices for data storage and information processing. "Electrons carry a charge as well as spin-angular momentum. In a typical charge current, electrons' spin-angular-momentum...

Speeding up storage by a thousand times with 'spin current'

Speeding up storage by a thousand times with 'spin current'

TU/e researchers show promising technology in Nature Communications 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...

'Melbourne Shuffle' secures data in the cloud

'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 users access data on cloud servers....

Rice's silicon oxide memories catch manufacturers' eye

Rice's silicon oxide memories catch manufacturers' eye

Use of porous silicon oxide reduces forming voltage, improves manufacturability Rice University's 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. First discovered five years ago, Rice's silicon oxide memories are a type of two-terminal,...
