'Prevent death' message more effective than 'save life' in blood donation campaigns

'Prevent loss' message better than 'provide benefits' to increase volunteerism

2013-03-07
(Press-News.org) Subtle changes in messaging can have a profound impact on the effectiveness of charitable messages such as calls for blood donations, according to research published March 6 in the open access journal PLOS ONE by Eileen Chou from the University of Virginia and co-author Keith Murnighan at Northwestern University.

Though chronic shortages in U.S blood banks could be alleviated by a small increase in the number of blood donors, people are not always motivated enough to help. In the current study, researchers collaborated with the Red Cross to assess the effects of changing the urgency and messaging of a call for blood donations. The scientists found that on a college campus, describing blood donations as a way to "prevent a death" rather than "save a life" significantly increased the rate of donations.

In a second study, the researchers assessed the effects of these slight changes in framing a charitable message on people's emotional motivation for a monetary donation. Here, they found that framing an appeal as "helping people to avoid a loss" rather than "helping people to gain benefits" led to increased intentions to volunteer and more helping behavior. Volunteers presented with such "prevention of loss" messages were also more likely to expect larger donations to their cause. "These findings demonstrated a simple, reliable, and effective method for charities to significantly increase important helping behaviors," Chou said.

Siberian fossil revealed to be one of the oldest known domestic dogs

2013-03-07
Analysis of DNA extracted from a fossil tooth recovered in southern Siberia confirms that the tooth belonged to one of the oldest known ancestors of the modern dog, and is described in research published March 6 in the open access journal PLOS ONE by Anna Druzhkova from the Institute of Molecular and Cellular Biology, Russian Federation, and colleagues from other institutions. Human domestication of dogs predates the beginning of agriculture about 10,000 years ago, but when modern dogs emerged as a species distinct from wolves is still unclear. Although some previous ...

Study: Brain injury may be autoimmune phenomenon, like multiple sclerosis

2013-03-07
Most scientists are starting to agree that repeat, sub-concussive hits to the head are dangerous and linked to neurological disorders later in life. A new collaborative study, though, attempted to find out why – and discovered that damage to the blood-brain barrier and the resulting autoimmune response might be the culprit. Published in journal PLOS ONE by the University of Rochester Medical Center and the Cleveland Clinic, the research suggests a new way of thinking about concussions: That the brain degeneration observed among professional football players (including ...

Salt identified as autoimmune trigger

2013-03-07
For the past few decades, health officials have been reporting increases in the incidence of autoimmune diseases such as multiple sclerosis (MS). Now researchers at Yale School of Medicine, Harvard Medical School and the Broad Institute have identified a prime suspect in the mystery — dietary salt. In the March 6 issue of the journal Nature, Yale researchers showed that salt can induce and worsen pathogenic immune system responses in mice and that the response is regulated by genes already implicated in a variety of autoimmune diseases. In accompanying papers in the ...

Measuring the universe more accurately than ever before

Measuring the universe more accurately than ever before
2013-03-07
Astronomers survey the scale of the Universe by first measuring the distances to close-by objects and then using them as standard candles [1] to pin down distances further and further out into the cosmos. But this chain is only as accurate as its weakest link. Up to now finding an accurate distance to the Large Magellanic Cloud (LMC), one of the nearest galaxies to the Milky Way, has proved elusive. As stars in this galaxy are used to fix the distance scale for more remote galaxies, it is crucially important. But careful observations of a rare class of double star have ...

Folate and vitamin B12 reduce disabling schizophrenia symptoms in some patients

2013-03-07
Adding the dietary supplements folate and vitamin B12 to treatment with antipsychotic medication improved a core symptom component of schizophrenia in a study of more than 100 patients. The study focused on negative symptoms of schizophrenia – which include apathy, social withdrawal, and a lack of emotional expressiveness. While the level of improvement across all participants was modest, results were more significant in individuals carrying specific variants in genes involved with folate metabolism. The report from a team based at Massachusetts General Hospital (MGH) will ...

Feinstein Institute researcher discovers new protein regulator of taste

2013-03-07
MANHASSET, NY – In collaboration with other research institutions, a Feinstein Institute for Medical Research investigator discovered a new protein that controls the sense of taste. The findings are published in the March issue of Nature. In a search for new proteins involved in the progression of Alzheimer's disease, Philippe Marambaud, PhD, an investigator in the Litwin-Zucker Research Center for the Study of Alzheimer's Disease at the Feinstein Institute, discovered the protein calcium homeostasis modulator 1 (CALHM1) in 2008. CALHM1 represents a new family of pore-forming ...

Circuitry of cells involved in immunity, autoimmune diseases exposed

2013-03-07
Cambridge and Boston, MA. Wed. March 6, 2013 – New work from the Broad Institute's Klarman Cell Observatory, Brigham and Women's Hospital, Harvard University, MIT, and Yale University expands the understanding of how one type of immune cell – known as a T helper 17 or Th17 cell – develops, and how its growth influences the development of immune responses. By figuring out how these cells are "wired," the researchers make a surprising connection between autoimmunity and salt consumption, highlighting the interplay of genetics and environmental factors in disease susceptibility. ...

Monell scientists help identify a missing link in taste perception

2013-03-07
PHILADELPHIA (March 6, 2013) -- Working with a multidisciplinary consortium of 19 researchers from nine institutions, Monell scientists have provided critical information to identify CALHM1, a channel in the walls of taste receptor cells, as a necessary component in the process of sweet, bitter, and umami (savory) taste perception. When sweet, bitter and umami molecules reach the tongue, they activate taste receptors in specialized cells called Type II taste cells. "The question that the consortium wanted to answer is, 'how do these taste cells tell the brain that they ...

How the body's energy molecule transmits 3 types of taste to the brain

How the bodys energy molecule transmits 3 types of taste to the brain
2013-03-07
PHILADELPHIA – Saying that the sense of taste is complicated is an understatement, that it is little understood, even more so. Exactly how cells transmit taste information to the brain for three out of the five primary taste types was pretty much a mystery, until now. A team of investigators from nine institutions discovered how ATP – the body's main fuel source– is released as the neurotransmitter from sweet, bitter, and umami, or savory, taste bud cells. The CALHM1 channel protein, which spans a taste bud cell's outer membrane to allow ions and molecules in and out, ...

Study identifies new risk factor for heart disease among kidney dialysis patients

2013-03-07
BOSTON– Kidney failure affects 25 million individuals in the U.S. and many more throughout the world. Loss of kidney function means the majority of these patients must undergo dialysis treatments to remove excess fluids and waste products. Although dialysis therapy coupled with medication has improved the life expectancy for people with kidney failure, for unknown reasons, patients' risk of sudden heart failure and death remains 10 to 20 times greater than average. Now, a study led by researchers at Beth Israel Deaconess Medical Center (BIDMC) and Massachusetts General ...
