Adding new members to group increases distrust among older members, impacts coordination

Changing group members decreases coordination, increases distrust among older group members

2013-01-31
(Press-News.org) Adding a new member to a working group can create distrust between members and hinder group functions, but a new study suggests that the distrust created is between older group members rather than about the newcomers- especially when previous group performance with just the older group members is poor. The results are part of a study published January 30 in the open access journal PLOS ONE by Matthew McCarter and Roman Sheremeta from Chapman University (U.S).

Previous studies report that changing members in an existing group hurts group performance, but the underlying reasons have been unclear. To identify these, the researchers in this study asked participants to play a 4-person coordination game. After a group had played, two members of the group were replaced and the newly formed group asked to repeat the game.

The authors found that replacing old group members with new individuals decreased trust across the group, which caused a drop in the group's performance. This effect was mitigated if the group knew the newcomers' performance history, but only if the new members also knew the older members' history.

Leading by the nose: Star-nosed mole reveals how mammals perceive touch, pain
2013-01-31
The most sensitive patch of mammalian skin known to us isn't human but on the star-shaped tip of the star-nosed mole's snout. Researchers studying this organ have found that the star has a higher proportion of touch-sensitive nerve endings than pain receptors, according to a study published January 30 in the open access journal PLOS ONE by Diana Bautista and colleagues from the University of California, Berkeley and Vanderbilt University. Touch and pain are closely intertwined sensations, but very little is known about how these sensations are detected in our cells. In ...

Tapeworm eggs discovered in 270 million year old fossil shark feces

2013-01-31
A cluster of tapeworm eggs discovered in 270-million-year-old fossilized shark feces suggests that intestinal parasites in vertebrates are much older than previously known, according to research published January 30 in the open access journal PLOS ONE by Paula Dentzien-Dias and colleagues from the Federal University of Rio Grande, Brazil. Remains of such parasites in vertebrates from this era are rare- of 500 samples examined, only one revealed the tapeworm eggs. This particular discovery helps establish a timeline for the evolution of present-day parasitic tapeworms ...

Forsyth scientists gain new understanding of latent tuberculosis

2013-01-31
Scientists at the Forsyth have gained new insight on how Tuberculosis (TB) remains a global epidemic. Although drugs have been available to fight TB for 50 years, the disease still infects nearly 2.2 billion people worldwide and causes 1.7 million annual deaths. This is largely attributed to the bacteria's ability to stay dormant in the human body and later resurface as active disease. The Forsyth team, and its collaborators from Stanford University, has recently discovered that Mycobacterium tuberculosis, the bacteria that causes TB, can lay dormant and thrive within ...

Itching for new help for eczema: Recently identified immune cells possible therapeutic target

Itching for new help for eczema: Recently identified immune cells possible therapeutic target
2013-01-31
PHILADELPHIA - The increasing incidence of allergic skin diseases, and the accompanying economic burden and heightened risk of developing other allergic conditions, have spurred researchers to look for better ways to control these immune system-based disorders. Atopic dermatitis, more commonly called eczema, now affects 10 to 20 percent of children in the United States and direct health-care costs exceed $3 billion, according to the National Institute of Arthritis and Musculoskeletal and Skin Diseases. What's more, up to 50 percent of children with atopic dermatitis ...

Scientists may have received millions in duplicate funding

Scientists may have received millions in duplicate funding
2013-01-31
Big Data computation at the Virginia Bioinformatics Institute at Virginia Tech reveals that over the past two decades funding agencies may have awarded millions and possibly billions of dollars to scientists who submitted the same grant request multiple times — and accepted duplicate funding. An analysis led by Harold R. Garner, a professor at Virginia Tech, not only indicates that millions in funding may have been granted and used inappropriately, it points to techniques to uncover existing instances of duplicate funding and ways to prevent it in the future. The analysis ...

Setting the stage for a new paradigm in treatment of heart failure

Setting the stage for a new paradigm in treatment of heart failure
2013-01-31
CHAPEL HILL, N.C. – Despite a substantial increase in the number of people suffering the debilitating and often deadly effects of heart failure, treatments for the condition have not advanced significantly for at least 10 years. An analysis by researchers at the University of North Carolina School of Medicine shows new breakthroughs could be closer than we thought. The analysis points to striking similarities between heart cells in patients with heart failure and brain cells in patients with Alzheimer's disease, raising the possibility that some treatment approaches being ...

Current evidence does not support selenium for preventing heart disease in well-nourished adults

2013-01-31
A systematic review published today in The Cochrane Library finds that in well-nourished adults current evidence does not support selenium for preventing heart disease. The review suggests that taking selenium supplements does not reduce a person's risk of developing heart disease, although most evidence is currently limited to healthy American adults. Diet is a key factor influencing heart disease risk. Selenium is one dietary element that could potentially play a role in preventing heart disease by protecting against oxidative stress and inflammation. It is a common ...

Brain activity study lends insight into schizophrenia

2013-01-31
Magnetic fields produced by the naturally occurring electrical currents in the brain could potentially be used as an objective test for schizophrenia and help to better understand the disease, according to new research published today. A team of researchers from Plymouth and Spain have used the non-invasive magnetoencephalogram (MEG) technique to find two spectral features that are significantly different in schizophrenia patients compared to healthy control subjects. Furthermore, they found that there were four spectral features in the brain signals of schizophrenia ...
