Paper-and-scissors technique rocks the nano world: Future nanofluidic devices for batteries, water purification systems

Posted: 14 Nov 2012 02:29 PM PST

Sometimes simplicity is best. Researchers have discovered an easy way to make nanofluidic devices: using paper and scissors. And they can cut a device into any shape and size, adding to the method's versatility. Nanofluidic devices are attractive because their thin channels can transport ions -- and with them a higher than normal electric current -- making them promising for use in batteries and new systems for water purification, harvesting energy and DNA sorting.

Bug repellent for supercomputers proves effective

Posted: 14 Nov 2012 10:47 AM PST

Researchers have used the Stack Trace Analysis Tool, a highly scalable, lightweight tool to debug a program running more than one million MPI processes on the IBM Blue Gene/Q-based Sequoia supercomputer.

Scientists 'clone' carbon nanotubes to unlock their potential for use in electronics

Posted: 14 Nov 2012 10:47 AM PST

Scientists have developed a method of "cloning" carbon nanotubes for use as semiconductors in electronics.

In financial ecosystems, big banks trample economic habitats and spread fiscal disease

Posted: 14 Nov 2012 10:46 AM PST

Researchers have applied methods inspired by ecosystem stability and contagion models to banking meltdowns and found that large national and international banks wield an influence and potentially destructive power that far exceeds their actual size. As a result, the capital that current regulations require large banks to maintain should be based on the institution's systemic importance.

Sisyphean task for polar molecules

Posted: 14 Nov 2012 10:40 AM PST

A new cooling method for polyatomic molecules paves the way for the investigation of molecular gases near absolute zero temperature.

Life and death in a star-forming cloud

Posted: 14 Nov 2012 08:38 AM PST

The aftershock of a stellar explosion rippling through space is captured in this new view of supernova remnant W44, which combines far-infrared and X-ray data from ESA's Herschel and XMM-Newton space observatories.

Nanometer-scale diamond tips improve nano-manufacturing

Posted: 14 Nov 2012 08:38 AM PST

One of the most promising innovations of nanotechnology has been the ability to perform rapid nanofabrication using nanometer-scale tips. The fabrication speed can be dramatically increased by using heat. High speed and high temperature have been known to degrade the tip… until now. Researchers have created a new type of nano-tip for thermal processing, which is made entirely out of diamond.

Lost in space: Rogue planet spotted? Orphaned world may help to explain how planets and stars form

Posted: 14 Nov 2012 05:34 AM PST

Astronomers using ESO's Very Large Telescope and the Canada-France-Hawaii Telescope have identified a body that is very probably a planet wandering through space without a parent star. This is the most exciting free-floating planet candidate so far and the closest such object to the Solar System at a distance of about 100 light-years. Its comparative proximity, and the absence of a bright star very close to it, has allowed the team to study its atmosphere in great detail. This object also gives astronomers a preview of the exoplanets that future instruments aim to image around stars other than the Sun.

Metals versus microbes: The biocidal effect of metalloacid-coated surfaces

Posted: 13 Nov 2012 06:46 PM PST

A new study reports of a phenomenon that could help control the spread of hospital-acquired infections: a surface-coating of metalloacids kills off microbial strains, even in multidrug-resistant microorganisms.
