Girls have a harder time than boys adjusting socially without a common language

EAST LANSING, Mich. — Girls who don't share a common language may have more difficulty adjusting socially than boys, according to surprising new Michigan State University research looking at language acquisition among young children.

A study of 3- to 6-year-olds attending an international school in Beijing found that in general, girls had more social adjustment problems than boys. The students, representing 16 nationalities, were immersed in both Chinese and English, meaning each child was learning at least one new language.

Receptor could halt blinding diseases, stop tumor growth, preserve neurons after trauma

Montreal, October 6, 2008 – An international team of researchers has discovered what promises to be the on-off switch behind several major diseases. In the advance online edition of today's Nature Medicine, scientists from Sainte-Justine Hospital Research Center, the Université de Montréal and the Institut national de la santé et de la recherche médicale (INSERM) in France report how the GPR91 receptor contributes to activate unchecked vascular growth that causes vision loss in common blinding diseases.

Pediatric study finds alternatives for radiation of low-grade brain tumors

HOUSTON - A multi-institutional study led by researchers at The University of Texas M. D. Anderson Cancer Center has found that using chemotherapy alone and delaying or avoiding cranial radiation altogether can be effective in treating pediatric patients with unresectable or progressive low-grade glioma. The study was presented Sunday at the 40th annual International Society of Pediatric Oncology Meeting in Berlin, Germany.

Landmark discovery of 'engine' that drives cell movement

How a cell assembles its internal machinery required for cell movement has been revealed for the first time. The discovery, by scientists in Singapore, is published in the October 2008 issue of Cell.

This research by Thomas Leung, Ph.D., and his team in the GSK-IMCB Group at the Institute of Molecular and Cell Biology (IMCB), under Singapore's Agency for Science, Technology and Research (A*STAR), is fundamental to the understanding of how a cell responds to its external environment.

Neurotransmitter defect may trigger autoimmune disease

A potentially blinding neurological disorder, often confused with multiple sclerosis (MS), has now become a little less mysterious. A new study by researchers at the Mayo Clinic in Rochester, Minnesota, may have uncovered the cause of Devic's disease. Their new study, which will appear online on October 6th in the Journal of Experimental Medicine, could result in new treatment options for this devastating disease.

Seeing race and seeming racist? Whites go out of their way to avoid talking about race

WASHINGTON – White people – including children as young as 10 -- may avoid talking about race so as not to appear prejudiced, according to new research. But that approach often backfires as blacks tend to view this "colorblind" approach as evidence of prejudice, especially when race is clearly relevant.

Food for thought -- regulating energy supply to the brain during fasting

LA JOLLA, CA—If the current financial climate has taught us anything, it's that a system where over-borrowing goes unchecked eventually ends in disaster. It turns out this rule applies as much to our bodies as it does to economics. Instead of cash, our body deals in energy borrowed from muscle and given to the brain.

Children aware of white male monopoly on White House

AUSTIN, Texas—Challenging the idea that children live in a color or gender blind world, a new study from The University of Texas at Austin reveals most elementary-school-age children are aware there has been no female, African-American, or Hispanic President of the United States. And, many of the children attribute the lack of representation to discrimination.

Viewers will receive greatest benefit in presidential town hall debate

Next Tuesday night, Senators John McCain and Barack Obama will meet on the debate stage for their second presidential debate, but this time they will not be alone. The candidates will be joined by dozens of "undecided" citizens eager to interrogate the two presidential hopefuls. While political strategists and media pundits are busy pondering which candidate is best served by such encounters, Mitchell McKinney, a University of Missouri associate professor of communication and presidential debate expert, says that citizens at home viewing the debate may be the greatest beneficiaries.

Obese diners choose convenience and overeating at Chinese buffets

When dining at Chinese Buffets, overweight individuals serve themselves and eat differently than normal weight individuals. This may lead them to overeat, according to a recent study by Cornell University's Food and Brand Lab. Compared to normal weight diners, overweight individuals sat 16 feet closer to the buffet, faced the food, used larger plates, ate with forks instead of chopsticks, and served themselves immediately instead of browsing the buffet.

Egalitarian revolution in the Pleistocene?

Although anthropologists and evolutionary biologists are still debating this question, a new study, published in the open-access journal PLoS ONE, supports the view that the first egalitarian societies may have appeared tens of thousands of years before the French Revolution, Marx, and Lenin. These societies emerged rapidly through intense power struggle and their origin had dramatic implications for humanity.

The structure of the Mre11 protein bound to DNA

BERKELEY, CA – Repairing breaks in the two strands of the DNA double helix is critical for avoiding cancer. In humans and other organisms, a molecular machine called the MRN complex is responsible for finding and signaling double-strand breaks (DSBs), then launching the error-free method of DNA repair called homologous recombination.

Bullying of teenagers online is common, UCLA psychologists report

Nearly three in four teenagers say they were bullied online at least once during a recent 12-month period, and only one in 10 reported such cyber-bullying to parents or other adults, according to a new study by UCLA psychologists.

Of those who were bullied online, 85 percent also have been bullied at school, the psychologists found. The probability of getting bullied online was substantially higher for those who have been the victims of school bullying.

UCR researchers propose minocycline as a promising drug for patients with Fragile X syndrome

RIVERSIDE, Calif. – A UC Riverside-led team of biomedical scientists has found that a readily available drug called minocycline, used widely to treat acne and skin infections, can be used to treat Fragile X syndrome, the most common inherited cause of mental impairment and the most common cause of autism.

The study's findings have already impacted future therapies, with the approval of a new clinical trial in Toronto, Canada, that will test minocycline in patients with Fragile X.

Survey confirms parents' fears, confusion over autism

Melbourne, Fla. — Oct. 3, 2008 — The first national survey of attitudes toward autism reveals that a small but significant percentage of people still believe the disease is caused by childhood vaccines. The survey of 1000 randomly selected adults was conducted for the Florida Institute of Technology.
