Study: Young women with sexy social media photos seen as less competent

Posted: 14 Jul 2014 03:24 PM PDT

Girls and young women who post sexy or revealing photos on social media sites are viewed by their female peers as less attractive and less competent to perform tasks, a new study indicates. One researcher's advice for girls and young women is to select social media photos that showcase their identity rather than her appearance, such as one from a trip or one that highlights participation in a sport or hobby.

Labs characterize carbon for lithion-ion batteries

Posted: 14 Jul 2014 03:24 PM PDT

Researchers have found a universal descriptor of charge-transfer binding properties for carbon-based lithium-ion batteries. The model is based on intrinsic electronic characteristics of materials used as battery anodes. These include the material's quantum capacitance (the ability of the material to absorb charge) and the material's absolute Fermi level, which determines how many lithium ions may bond to the electrodes.

Online advertising: Using competitors' brand name as a keyword can backfire

Posted: 14 Jul 2014 10:39 AM PDT

Buying keywords of a popular competitors' brand names on search engines such as Google and Bing can backfire according to a new study. Firms often buy brand names of better-known rivals' to reach buyers looking for rivals' products or to be seen in the company of more popular companies. However, contrary to common belief, when an inferior brand's ad is seen next to a superior brand's web links, a large difference in reputation is further magnified in the minds of consumers.

Researchers demonstrate novel, tunable nanoantennas

Posted: 14 Jul 2014 09:28 AM PDT

Scientists have developed a novel, tunable nanoantenna that paves the way for new kinds of plasmonic-based optomechanical systems, whereby plasmonic field enhancement can actuate mechanical motion. The team's fabrication process shows for the first time an innovative way of fabricating plasmonic nanoantenna structures under the SEM, which avoids complications such as proximity effects from conventional lithography techniques.

Squishy robots: Phase-changing material could allow even low-cost robots to switch between hard and soft states

Posted: 14 Jul 2014 09:28 AM PDT

In the movie 'Terminator 2,' the shape-shifting T-1000 robot morphs into a liquid state to squeeze through tight spaces or to repair itself when harmed. Now a phase-changing material built from wax and foam, and capable of switching between hard and soft states, could allow even low-cost robots to perform the same feat.

New technology for diagnosis of cancer cells

Posted: 14 Jul 2014 09:28 AM PDT

The type of therapy a cancer patient receives largely depends on the eye of a pathologist. However, human judgment is, by its very nature, subject to variation. To enhance the quality of diagnosis, scientists have developed a software that identifies cell structures and proteins in order to provide reliable diagnoses.

Nano-sized silicon oxide electrode for the next generation lithium ion batteries

Posted: 14 Jul 2014 07:57 AM PDT

A new article reports on an approach with industrial potential to produce nano-sized composite silicon-based powders as negative electrodes for the next generation lithium ion batteries.

3D printed anatomy to mark a new era for medical training

Posted: 14 Jul 2014 07:41 AM PDT

The creators of a unique kit containing anatomical body parts produced by 3D printing say it will revolutionize medical education and training, especially in countries where cadaver use is problematic. The '3D Printed Anatomy Series' is thought to be the first commercially available resource of its kind. The kit contains no human tissue, yet it provides all the major parts of the body required to teach anatomy of the limbs, chest, abdomen, head and neck.

Quantum computers? First photonic router demonstrated

Posted: 14 Jul 2014 07:41 AM PDT

Scientists have demonstrated for the first time a photonic router -- a quantum device based on a single atom that enables routing of single photons by single photons. This achievement is another step toward overcoming the difficulties in building quantum computers.

Technology produces clean-burning hydrogen fuel cheaply using carbon nanotubes

Posted: 14 Jul 2014 07:41 AM PDT

Researchers have developed a technology that could overcome a major cost barrier to make clean-burning hydrogen fuel -- a fuel that could replace expensive and environmentally harmful fossil fuels. The new technology is a novel catalyst that performs almost as well as cost-prohibitive platinum for so-called electrolysis reactions, which use electric currents to split water molecules into hydrogen and oxygen. The Rutgers technology is also far more efficient than less-expensive catalysts investigated to-date.

Internet browsing can improve millennial attention to workplace tasks

Posted: 14 Jul 2014 07:03 AM PDT

A recent research article has empirically test the theory of Workplace Internet Leisure Browsing, its effectiveness in restoring overall attention to workplace tasks, and attitudes toward workplace Internet browsing among differing age groups.  The implication of this dual study is that short breaks that include non-work related Internet browsing can potentially improve younger workers' (under the age of 30) attention to work tasks.

Flashes of light on a superconductor

Posted: 14 Jul 2014 07:03 AM PDT

A new technique has been developed based on applying short flashes of light to observe and analyze the features of a superconductor at high critical temperature, a material with major prospects for technological applications. In addition to providing an explanation for the peculiar behavior of the material, the study also opens to the possibility of controlling its characteristics by means of laser pulses.

Pumping efficiency into electrical motors

Posted: 14 Jul 2014 07:01 AM PDT

Researchers are using new magnetic materials to develop revolutionary electrical motors and generators which promise significant energy savings.

Every full moon, Landsat looks to the moon

Posted: 13 Jul 2014 12:59 PM PDT

Every full moon, Landsat 8 turns its back on Earth. As the satellite's orbit takes it to the nighttime side of the planet, Landsat 8 pivots to point at the moon. It scans the distant lunar surface multiple times, then flips back around to continue its task of collecting land-cover information of the sunny side of Earth below.

Li-fi protocol allows use of the Internet at the speed of light

Posted: 13 Jul 2014 12:54 PM PDT

Sisoft Company in Mexico has developed a technology that can illuminate a large work space, an auditorium or an office, while providing full mobile Internet to every device that comes into the range of the light spectrum.
