NASA's Swift narrows down origin of important supernova class Posted: 20 Mar 2012 04:58 PM PDT Studies using X-ray and ultraviolet observations from NASA's Swift satellite provide new insights into the elusive origins of an important class of exploding star called Type Ia supernovae.

Cassini sees Saturn stressing out Enceladus Posted: 20 Mar 2012 01:35 PM PDT Images from NASA's Cassini spacecraft have, for the first time, enabled scientists to correlate the spraying of jets of water vapor from fissures on Saturn's moon Enceladus with the way Saturn's gravity stretches and stresses the fissures.

Nuclear fusion simulation shows high-gain energy output Posted: 20 Mar 2012 01:15 PM PDT A computer simulation that shows a release of high-yield fusion energy much greater than previously achieved at Sandia's Z accelerator is being prepared for testing in 2013.

New method for cleaning up nuclear waste Posted: 20 Mar 2012 12:19 PM PDT A new crystalline compound can be tailored to safely absorb radioactive ions from nuclear waste streams, experts say.

Explosive stars with good table manners Posted: 20 Mar 2012 11:20 AM PDT In two comprehensive studies of SN 2011fe -- the closest Type Ia supernova in the past two decades -- there is new evidence that indicates that the white dwarf progenitor was a particularly picky eater, leading scientists to conclude that the companion star was not likely to be a sun-like star or an evolved giant.

Engineers enlist weather model to optimize offshore wind plan Posted: 20 Mar 2012 08:57 AM PDT Using a sophisticated weather model, environmental engineers have defined optimal placement of a grid of four wind farms off the US East Coast. The model successfully balances production at times of peak demand and significantly reduces costly spikes and zero-power events.

A basic -- and slightly acidic -- solution for hydrogen storage Posted: 20 Mar 2012 08:57 AM PDT Sometimes, solutions for hard problems can turn out to be pretty basic. That's especially true researchers where the solution for a hard problem they were working on turned out to be pretty basic ... and also a bit acidic. The hard problem they were working on was how to store hydrogen fuel.

Better organic electronics: Researchers show the way forward for improving organic and molecular electronic devices Posted: 20 Mar 2012 08:56 AM PDT Scientists have provided the first experimental determination of the pathways by which electrical charge is transported from molecule-to-molecule in an organic thin film. These results also show how such organic films can be chemically modified to improve conductance for superior organic electronics.

Super-Earth unlikely able to transfer life to other planets Posted: 20 Mar 2012 08:56 AM PDT While scientists believe conditions suitable for life might exist on the so-called "super-Earth" in the Gliese 581 system, it's unlikely to be transferred to other planets within that solar system.

Detection of cosmic effect may bring universe's formation into sharper focus Posted: 20 Mar 2012 08:56 AM PDT The first observation of a cosmic effect theorized 40 years ago could provide astronomers with a more precise tool for understanding the forces behind the universe's formation and growth, including the enigmatic phenomena of dark energy and dark matter.
