PHILADELPHIA (February 24, 2014) – The increasing use of expensive medical imaging procedures in the U.S. like positron emission tomography (PET) scans is being driven, in part, by patient decisions made after obtaining information from lay media and non-experts, and not from health care providers.

That is the result from a three-year-long analysis of survey data, and is published in the article , "Associations between Cancer-Related Information Seeking and Receiving PET Imaging for Routine Cancer Surveillance – An Analysis of Longitudinal Survey Data," appearing in the journal Cancer Epidemiology, Biomarkers & Prevention.

When it comes to the names of lipsticks, anyone who has attempted to combine the ‘Presentation of Self’ theories of Erving Goffman and the semiotic modelling methods of Roland Gérard Barthes could well consult the work of professor Debra Merskin (of the School of Journalism and Communication at the University of Oregon, US), who has categorised the names of no less than 1,722 lipsticks.

“The names of lipsticks and how they penetrate women’s psyches as semiotic tools used in branding are the foci of the present study.”

The professor’s study delineated 14 name-categories for the lipsticks, and then allocated the names accordingly – the results are listed here in order of their popularity.

On face value, if you read Anita Clayton's Huffington Post piece entitled “The FDA, Sexual Dysfunction and Gender Inequality,” you could not come to any conclusion other that the FDA is overtly sexist.

People believe that they know what moves them to act; marketers seem to agree.  To learn what people think and feel about a product or message, just ask them, right?

In times of easy access to the Internet and cheap travel, we consider ourselves part of a global society, but how connected this really makes us will surprise many of us.

The criticism of wind farms is that they are expensive, don't product enough electricity to be meaningful and change the weather patterns even a thousand miles away.

That may have a benefit; they may weaken hurricanes before landfall.

Imagine a 2012 US presidential election without New York City media whipping up a "Super Storm" and implying that Republican candidate Mitt Romney would cause hurricanes? He still would have lost but it would have given environmentalists one less reason to be against protecting people by embracing common-sense changes like waterproof subway doors and a seawall.

New research from Queen Mary University of London has discovered 11 new DNA sequence variants in genes influencing high blood pressure and heart disease.

Identifying the new genes contributes to our growing understanding of the biology of blood pressure and, researchers believe, will eventually influence the development of new treatments. More immediately the study highlights opportunities to investigate the use of existing drugs for cardiovascular diseases.

Research led by a team at Women & Infants Hospital of Rhode Island and The Warren Alpert Medical School of Brown University has been published in the February 10, 2014 online edition of Pediatrics, the official journal of the American Academy of Pediatrics. The research indicates that premature babies benefit from being exposed to adult talk as early as possible.

SEATTLE – Pancreas cancer is notoriously impervious to treatment and resists both chemotherapy and radiotherapy. It has also been thought to provide few targets for immune cells, allowing tumors to grow unchecked. But new research from Fred Hutchinson Cancer Research Center shows that pancreas cancer "veils" itself from the immune system by recruiting specialized immune suppressor cells. The research team also found that removing these cells quickly triggers a spontaneous anti-tumor immune response.

The findings, published Feb. 20 in Gut, give hope for future immunotherapy strategies against this deadly and aggressive cancer.

Boy scouts know this, and now we'll let you in on a secret too: if you've run out of drinking water during a lakeside camping trip, there's a simple solution. Break off a branch from the nearest pine tree, peel away the bark, and slowly pour lake water through the stick. This improvised filter will trap any bacteria, producing fresh, uncontaminated water. 

An MIT team has discovered that this low-tech filtration system can produce up to four liters of drinking water a day — enough to quench the thirst of a typical person.
