NASA investigating the life of Comet ISON Posted: 02 Dec 2013 02:19 PM PST After several days of continued observations, scientists continue to work to determine and to understand the fate of Comet ISON: There's no doubt that the comet shrank in size considerably as it rounded the sun and there's no doubt that something made it out on the other side to shoot back into space.

Scientists build a low-cost, open-source 3-D metal printer Posted: 02 Dec 2013 02:19 PM PST Using under $1,500 worth of materials, scientists have built a 3-D metal printer than can lay down thin layers of steel to form complex geometric objects.

Process holds promise for production of synthetic gasoline from carbon dioxide Posted: 02 Dec 2013 10:48 AM PST A chemical system can efficiently perform the first step in the process of creating syngas, gasoline and other energy-rich products out of carbon dioxide.

Molecular imaging tracers help determine treatment plans for brain metastases Posted: 02 Dec 2013 10:48 AM PST Imaging with the molecular imaging tracer 18F-FDOPA can help distinguish radiation-induced lesions from new tumor growth in patients who have been treated with radiation for brain metastases, according to new research. Using this amino acid tracer, researchers found that physicians could accurately differentiate the two types of lesions 83 percent of the time. Progression-free survival could also be predicted through evaluating the 18F-FDOPA imaging results.

Understanding hearing Posted: 02 Dec 2013 10:48 AM PST Children learning to speak depend on functional hearing. So-called cochlear implants allow deaf people to hear again by stimulating the auditory nerve directly. Researchers are working to overcome current limits of the technology. They are investigating the implementation of signals in the auditory nerve and the subsequent neuronal processing in the brain.

When aluminum outshines gold: Aluminum's valuable plasmonic properties detailed Posted: 02 Dec 2013 10:48 AM PST Aluminum's plasmonic properties may make it far more valuable than gold and silver for certain applications. Researchers provide experimental and theoretical proof of the metal's potential.

Forget the needle; consider the haystack Posted: 02 Dec 2013 09:15 AM PST Computer scientists have developed a method to uncover hidden patterns in huge data collections. Using a mathematical method that calculates the likelihood of a pattern repeating throughout a subset of data, the researchers have been able to cut dramatically the time needed to find patterns in large collections of information such as social networks.

Nanorobot for transporting drugs in the body Posted: 02 Dec 2013 09:15 AM PST The first step has been taken towards developing a nanorobot that -- in the long run -- will enable the targeted transport of medications in the body.

New algorithm finds you, even in untagged photos Posted: 02 Dec 2013 09:12 AM PST A new algorithm has the power to profoundly change the way we find photos among the billions on social media sites such as Facebook and Flickr. The search tool uses tag locations to quantify relationships between individuals, even those not tagged in any given photo.

Amplifying our vision of the infinitely small Posted: 02 Dec 2013 09:10 AM PST Scientists have discovered a method to improve detection of the infinitely small.

New light shed on solar water-splitting process Posted: 02 Dec 2013 08:21 AM PST Scientists have provided new insight into how solar water-splitting cells work. An important and overlooked parameter, they report, is the ion-permeability of electrocatalysts used in water-splitting devices.

Most detailed catalog of galaxies traces evolution of the universe during last 10,000 million years Posted: 02 Dec 2013 08:20 AM PST Astronomers have now identified and classified more than half a million galaxies, after seven years of close observation of the universe.

Sorting good germs from bad, in bacterial world Posted: 02 Dec 2013 06:43 AM PST There are good E. coli and bad E. coli. Some live in your gut and help you keep healthy, others can cause serious disease -- even death. For pathologists, telling them apart has been a long and laborious task sometimes taking days. New technology using microscale electric field gradients now can tell the difference between good and bad bacteria in minutes from extremely small samples.

Novel rehabilitation device improves motor skills after stroke Posted: 02 Dec 2013 05:26 AM PST Using a novel stroke rehabilitation device that converts an individual's thoughts to electrical impulses to move upper extremities, stroke patients reported improvements in their motor function and ability to perform activities of daily living.

Defending against electromagnetic attacks Posted: 02 Dec 2013 05:25 AM PST Electromagnetic radiation is invisible to people, however electromagnetic fields can interfere with or damage electronic devices. A new measuring instrument can now determine the strength, frequency, and direction of the attack.
