Cell
Antioxidant controls spinal cord development
Researchers at the Johns Hopkins School of Medicine have discovered how one antioxidant protein controls the activity of another protein, critical for the development of spinal cord neurons. The research, publishing this week in Cell, describes a never-before known mechanism of protein control.

Alcoholism: Clinical & Experimental Research
Education and reward genes interact to influence alcoholism among Mexican-Americans
Interaction of gene/gene, gene/environment and environment/environment factors can contribute to alcoholism. New research looks at the influence of gene/environment interaction on alcoholism among Mexican-Americans. Findings show that interaction between education and a polymorphism of the reward gene contribute to severe alcoholism among Mexican-Americans.

Alcoholism: Clinical & Experimental Research
Early age at first drink may modify tween/teen risk for alcohol dependence
People who begin drinking at an early age are more likely to subsequently develop alcohol dependence (AD). A new study has found that age at first drink (AFD) may enhance the role of genetic factors that are already associated with vulnerability to AD symptoms. Heritable influences on AD symptoms were considerably greater in those who reported an AFD younger than 15 years of age.

Alcoholism: Clinical & Experimental Research
Too many bars in rural America linked to high suicide rates instead of idyllic life
A new study has examined the relationship between suicide and number of alcohol outlets. Results show that suicides -- both completed and attempted -- occurred at greater rates in rural community areas with greater bar densities. Completed suicide rates were lower among blacks and Hispanics, and higher among low-income, older whites living in rural areas.

New UAB study examines benefit of internet access, social media networking on seniors' health
Many elderly adults are increasingly isolated and grapple with depression, loneliness and declines in physical health. The UAB Department of Sociology and Social Work will use a five-year, $1.9 million National Institute on Aging grant to study the ability of computer use and social media networking to enhance the quality of life of elderly adults through online social connections and easier access to health information.

Building a complete metabolic model
Investigators at Burnham Institute for Medical Research, University of California, San Diego, the Scripps Research Institute, Genomics Institute of the Novartis Research Foundation and other institutions have constructed a complete model, including 3-D protein structures, of the central metabolic network of the bacterium Thermotoga maritima (T. maritima).

Older Americans: How they are faring in the recession
Older Americans have weathered the financial crisis relatively well, although many now expect to work longer than they did just a year ago, according to a University of Michigan study released on Capitol Hill Sept. 16.

Cell
Gene screen reveals 2-way communication between common biological pathways and body's daily clock
While scientists have known for several years that our body's internal clock helps regulate many biological processes, researchers have found that the reverse is also true: Many common biological processes -- including insulin metabolism -- regulate the clock, according to a new study. The new data suggests that someday physicians may be able to use small molecules that inhibit or stimulate these biological processes in order to influence a person's clock.

UCSF scientists illuminate how microRNAs drive tumor progression
UCSF researchers have identified collections of tiny molecules known as microRNAs that affect distinct processes critical for the progression of cancer. The findings, they say, expand researchers' understanding of the important regulatory function of microRNAs in tumor biology and point to new directions for future study and potential treatments.

Genetic hint for ridding the body of hepatitis C
More than seventy percent of people who contract hepatitis C will live with the virus that causes it for the rest of their lives, and some will develop serious liver disease including cancer. However, 30 to 40 percent of those infected somehow defeat the infection and get rid of the virus with no treatment.

UNC study: Color-coded chart improves parents' understanding of body mass index
A new study shows that parents are more likely to understand a body mass index chart if it's color-coded, like a traffic light, than the standard charts currently in use.

Scientists cure color blindness in monkeys
Writing online in the journal Nature, scientists from the University of Florida and the University of Washington cast a rosy light on the potential for gene therapy to treat adult vision disorders involving cone cells -- the most important cells for vision in people. Scientists used gene therapy to cure two squirrel monkeys of color blindness -- the most common genetic disorder in people.
