A new mouthwash developed by a microbiologist at the UCLA School of Dentistry is highly successful in targeting the harmful Streptococcus mutans bacteria that is the principal cause tooth decay and cavities.
In a recent clinical study, 12 subjects who rinsed just one time with the experimental mouthwash experienced a nearly complete elimination of the S. mutans bacteria over the entire four-day testing period. The findings from the small-scale study are published in the current edition of the international dental journal Caries Research. (more…)

Men who ate a low-fat diet with fish oil supplements for four to six weeks before having their prostate removed had slower cancer-cell growth in their prostate tissue than men who ate a traditional, high-fat Western diet, according to a study by researchers at UCLA’s Jonsson Comprehensive Cancer Center.
The researchers also found a change in the composition of cell membranes in both healthy cells and cancer cells in the prostates of men on the low-fat, fish oil–supplement diet. The membranes had heightened levels of omega-3 fatty acids from fish oil and decreased levels of omega-6 fatty acids from corn oil, which may directly affect the biology of the cells, though further studies are needed, said Dr. William Aronson, the study’s first author and a researcher with the Jonsson Cancer Center.

*Bacterial cells have gene mutations that allow them to ‘stick’ to the devices*
New research suggests that some patients develop a potentially deadly blood infection from their implanted cardiac devices because bacterial cells in their bodies have gene mutations that allow them to stick to the devices.
Geoscientists were the major contributors to the finding.
Proceedings of the National Academy of Sciences published the study results online this week. (more…)
*Divorce and remarriage affect beliefs about who should care for elder relatives*
COLUMBIA, Mo. – America’s elderly population will nearly double by 2050, according to a Pew Research report. As baby boomers enter retirement, concern exists as to who will care for them as they age. Traditionally, children have accepted the caregiving responsibilities, but those caregiving roles are becoming blurred as more families are affected by divorce and remarriage than in previous decades. Now, University of Missouri researchers have found that relationship quality trumps genetic ties when determining caregiving obligations.
Lawrence Ganong, a professor and co-chair in the MU Department of Human Development and Family Studies in the College of Human Environmental Sciences (HES), studied how divorce and remarriage affect beliefs about who should care for aging relatives. He found that relationship quality, a history of mutual help, and resource availability influence decisions about who cares for parents and stepparents. (more…)
*Facebook, Twitter and LinkedIn Post Mobile Growth of at Least 50 Percent*
*Majority of Mobile Social Networkers Read Posts from Brands While on Their Device*
RESTON, VA, October 20, 2011 – comScore, Inc., a leader in measuring the digital world, today released results of a study on mobile social media usage based on data from its comScore MobiLens service, which showed that 72.2 million Americans accessed social networking sites or blogs on their mobile device in August 2011, an increase of 37 percent in the past year. The study also provided new insights into how mobile users interact with social media, finding that more than half read a post from an organization, brand or event while on their mobile device.
