Innovative motion evaluation tool saves patients with back pain X-ray radiation exposure

Posted: 09 Jan 2014 03:03 PM PST

Those who have undergone extensive back surgery and need repeated X-rays to monitor their progress may soon have access to a new technology that skips the X-rays and repeated radiation exposure, opting instead for an innovative, noninvasive, non-X-ray device that evaluates spinal movement, according to a paper.

Battery development may extend range of electric cars

Posted: 09 Jan 2014 02:55 PM PST

Electric cars could travel farther on a single charge and more renewable energy could be saved for a rainy day if lithium-sulfur batteries can last longer. Scientists have now developed a novel anode that could quadruple the lifespan of these promising batteries.

Free code to help build better batteries

Posted: 09 Jan 2014 11:37 AM PST

Lithium-ion batteries, such as those used in electric vehicles, are in high demand, with a global market value expected to reach $33.1 billion in 2019. But their high price and short life need to be addressed before they can be used in more consumer, energy and medical products. Scientists are working to solve this problem buy developing optimal charging profiles for the batteries.

Unravelling the web of a cosmic creeply-crawly

Posted: 09 Jan 2014 10:26 AM PST

This new Hubble image is the best-ever view of a cosmic creepy-crawly known as the Tarantula Nebula, a region full of star clusters, glowing gas, and dark dust. Astronomers are exploring and mapping this nebula as part of the Hubble Tarantula Treasury Project, in a bid to try to understand its starry anatomy.

Astronomers discover new planet in Pisces constellation

Posted: 09 Jan 2014 10:25 AM PST

Astronomers have discovered a new giant planet located in a star system within the Pisces constellation. The planet, perhaps twice the mass of Jupiter, could help researchers learn more about how extrasolar planets are formed.

Fusion instabilities lessened by unexpected effect

Introduction of relatively weak magnetic fields into Sandia's Z machine unexpectedly lessened plasma instabilities that have sunk previous fusion efforts.

Hubble views stellar genesis in the Southern Pinwheel

Posted: 09 Jan 2014 09:49 AM PST

The vibrant magentas and blues in this Hubble image of the barred spiral galaxy M83 reveal that the galaxy is ablaze with star formation. The galactic panorama unveils a tapestry of the drama of stellar birth and death. The galaxy, also known as the Southern Pinwheel, lies 15 million light-years away in the constellation Hydra.

Surprising new class of 'hypervelocity stars' discovered escaping the galaxy

Posted: 09 Jan 2014 09:49 AM PST

Astronomers have discovered a surprising new class of "hypervelocity stars" – solitary stars moving fast enough to escape the gravitational grasp of the Milky Way galaxy.

Ultra-thin flexible transparent electronics can wrap around a hair

Posted: 09 Jan 2014 07:36 AM PST

Researchers are developing electronic components that are thinner and more flexible than before. They can even be wrapped around a single hair without damaging the electronics. This opens up new possibilities for ultra-thin, transparent sensors that are literally easy on the eye.

Magneto-optical nonreciprocal devices in silicon photonics

Posted: 08 Jan 2014 02:05 PM PST

In a paper published, researchers demonstrated the first optical isolator on silicon waveguide platforms.
