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.

PROVIDENCE, R.I. [Brown University] -- Advertising prescription drugs to consumers is forbidden in most of the world, but since U.S. guidelines were relaxed in 1997, such ads have become nearly ubiquitous in American media. In a newly published review, Brown University researchers examined what has been learned since then about the effect of all that advertising on psychiatric conditions. They found that the data are very limited, but what does exist suggests that ads succeed in driving prescribing with potentially mixed effects on patient care.

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.

DALLAS, Sept. 13, 2016 -- Smoking is associated with thicker heart walls and reduction in the heart's pumping ability, two factors associated with increased risk of heart failure, according to new research in the American Heart Association's journal Circulation: Cardiovascular Imaging.

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. 

Daniel Drucker's unofficial laboratory slogan is "I'd rather be third and right, than first and wrong." After 30 years, he has seen high-profile journal article after article proclaim the beginning of the end for diseases he studies like diabetes, gastrointestinal disease, and obesity, only for the findings to never be discussed again.

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.

A new study increases and strengthens the links that have led some to propose the "transposon theory of aging" centering on the rogue elements of DNA that break free in aging cells and rewrite themselves elsewhere in the genome.

They believe this is potentially creating lifespan-shortening chaos in the genetic makeups of tissues.

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.
