In a survey of online articles about preventing Alzheimer's disease, research finds that many online resources for preventing Alzheimer's disease are problematic and could be steering people in the wrong direction.

There was poor advice and one in five promoted products for sale--a clear conflict of interest, though hucksters like Joe Mercola, D.O., never acknowledge that.

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.
