Two new studies have found that large structural abnormalities in chromosomes, some of which have been associated with increased risk of cancer, can be detected in a small fraction of people without a prior history of cancer. The studies found that these alterations in chromosomes appear to increase with age, particularly after the age of 50, and may be associated with an increased risk for cancer... The results of the studies were published online May 6, 2012, in Nature Genetics.

NIH study indicates drug safe during pregnancy, but infants smaller at first birthday
Infants born to women who used the anti-HIV drug tenofovir as part of an anti-HIV drug regimen during pregnancy do not weigh less at birth and are not of shorter length than infants born to women who used anti-HIV drug regimens that do not include tenofovir during pregnancy, according to findings from a National Institutes of Health network study. However, at 1 year of age, children born to the tenofovir-treated mothers were slightly shorter and had slightly smaller head circumference — about 1 centimeter each, on average — than were infants whose mothers did not take tenofovir.

Wearing shoes and genomics are tied together in strategy to eliminate podoconiosis
Farmers in the highlands of southern Ethiopia scratch out a subsistence living from the region’s volcanic red clay. The soil supports the farms, but fine-grained, volcanic rock particles in the dirt threaten the farmers and their families. Continual exposure of bare feet to the volcanic soil causes 1 in 20 people to develop a painful inflammation of the lower extremities that, over time, leads to foot disfigurement. ... Now, researchers think they know why some 4 million people in at least 10 countries worldwide develop this incapacitating condition. One-fifth carry genetic variants that cause their immune system to react to the volcanic dust.

Scans reveal how genes alter circuit hub to shape temperament
A personality profile marked by overly gregarious yet anxious behavior is rooted in abnormal development of a circuit hub buried deep in the front center of the brain, say scientists at the National Institutes of Health. They used three different types of brain imaging to pinpoint the suspect brain area in people with Williams syndrome, a rare genetic disorder characterized by these behaviors. Matching the scans to scores on a personality rating scale revealed that the more an individual with Williams syndrome showed these personality/temperament traits, the more abnormalities there were in the brain structure, called the insula.

Infants' faces evoke species-specific patterns of brain activity in adults
Distinct patterns of activity — which may indicate a predisposition to care for infants — appear in the brains of adults who view an image of an infant face — even when the child is not theirs, according to a study by researchers at the National Institutes of Health and in Germany, Italy, and Japan. Seeing images of infant faces appeared to activate in the adult's brains circuits that reflect preparation for movement and speech as well as feelings of reward. The findings raise the possibility that studying this activity will yield insights not only into the caregiver response, but also when the response fails, such as in instances of child neglect or abuse.

For the first time, scientists have tracked the activity, across the lifespan, of an environmentally responsive regulatory mechanism that turns genes on and off in the brain's executive hub. Among key findings of the study by National Institutes of Health scientists: genes implicated in schizophrenia and autism turn out to be members of a select club of genes in which regulatory activity peaks during an environmentally-sensitive critical period in development. The mechanism, called DNA methylation, abruptly switches from off to on within the human brain's prefrontal cortex during this pivotal transition from fetal to postnatal life. As methylation increases, gene expression slows down after birth.
