Fabrics that can generate electricity from physical movement have been in the works for a few years. Now researchers at Georgia Institute of Technology have taken the next step, developing a fabric that can simultaneously harvest energy from both sunshine and motion.

Combining two types of electricity generation into one textile paves the way for developing garments that could provide their own source of energy to power devices such as smart phones or global positioning systems.

"This hybrid power textile presents a novel solution to charging devices in the field from something as simple as the wind blowing on a sunny day," said Zhong Lin Wang, a Regents professor in the Georgia Tech School of Materials Science and Engineering.

Entitlement--a personality trait driven by exaggerated feelings of deservingness and superiority--may lead to chronic disappointment, unmet expectations and a habitual, self-reinforcing cycle of behavior with dire psychological and social costs, according to new research by Case Western Reserve University.

In a new theoretical model, researchers have mapped how entitled personality traits may lead to a perpetual loop of distress, in a literature review published in the Psychological Bulletin.

"At extreme levels, entitlement is a toxic narcissistic trait, repeatedly exposing people to the risk of feeling frustrated, unhappy and disappointed with life," said Joshua Grubbs, the primary author of the paper and a recent PhD graduate in psychology from Case Western Reserve.

From skeletal remains found among ancient owl pellets, a team of scientists has recovered the first ancient DNA of the extinct West Indian mammal Nesophontes, meaning "island murder." They traced its evolutionary history back to the dawn of mammals 70 million years ago.

The authors, including Selina Brace, Jessica Thomas, Ian Barnes et al., published their findings in the advanced online edition of Molecular Biology and Evolution.

Using software tools developed by the marketing group Near Zero, which has developed open-source software tools to examine where experts agree and disagree and why, a research group hosted by the Carnegie Institution for Science's Department of Global Ecology has completed the largest expert survey yet of wind energy. 

If Canadian parents are going to get their kids to exercise more, they need more than just public awareness campaigns.

Parents exposed to one such national campaign were actually less confident they could increase their children's activity levels, according to a recent UBC study.

"With statistics outside this study showing 88 per cent of parents believe their children exercise enough and only seven per cent of kids meet recommended guidelines, it is clear more needs to be done," says Heather Gainforth, an assistant professor of health and exercise sciences at UBC's Okanagan campus. "While mass media campaigns appear to increase awareness, parents need the support of public policies and programs to help them successfully encourage behaviour change.

There are various hypotheses for the origin of the Moon but a chemistry analysis says it has disproved the leading one - that a low-energy impact left the proto-Earth and Moon shrouded in a silicate atmosphere. Instead, they say, a much more violent impact vaporized the impactor and most of the proto-Earth, expanding to form an enormous superfluid disk out of which the Moon eventually crystallized.

Researchers conducted risk calculation on the influence of the temporary suspension of cervical cancer vaccination based on vaccination rates for female Japanese born between 1993 and 2008. They clarified that the risk of HPV infection varies considerably depending on the birth year. The findings suggest that infection risk may be reduced if vaccination encouragement is resumed and target groups are extended to include those females that were at target vaccination age during the suspension period.

Experts often advise even openly gay and lesbian candidates to downplay their sexual orientation or risk losing votes, but David Niven, an assistant professor of political science at the University of Cincinnati, claimed at the annual meeting of the American Political Science Association in Philadelphia that not only does a gay or lesbian candidate's sexual orientation no longer pose a political disadvantage, but that it may actually help them win office.  

Researchers from the University of Birmingham have shed light onto the cognitive benefits of bilingualism, pointing to an enhanced ability to maintain attention and focus.

The results of the study, published in Bilingualism: Language and Cognition, suggest it is this improved attentional control that provides the 'bilingual advantage', rather than a better-than-average inhibitory control.
