The more obese a woman is when she becomes pregnant, the greater the likelihood that her newborn baby will have a congenital heart defect, a new study suggests. The finding raises concerns because 1 in 5 women are obese at the start of pregnancy in the United States.
Higher rates of colorectal cancer incidence and death among African-Americans may be driven less by biology and more by differences in health care use, according to a new study.
Scientists have developed a recording device that essentially melts into place, snugly fitting to the brain’s surface. The new technology allows for closer interaction between machines and living tissue, paving the way for more advanced implantable devices.

Taking vitamin C and E supplements starting in early pregnancy does not reduce the risk for pregnancy-associated hypertension and its complications, according to a new study.
The routine "heel-stick" blood test that screens for several disorders in newborns would fail to detect most cases of cytomegalovirus (CMV) infection, a leading cause of hearing loss in children. The new finding highlights the need for rapid, reliable and cost-effective screening methods that can identify the virus early in life.
A large genetic study has identified 3 new genes associated with the blinding eye disease age-related macular degeneration (AMD). Two of the genes are involved in the cholesterol pathway—a formerly unknown biological pathway for AMD disease development. The finding suggests new treatment and prevention approaches.

Some brain mechanisms that contribute to drug addiction in humans also play a role in compulsive eating and the development of obesity in rats, according to a new study. If true in people, the finding may open doors to new approaches for reducing obesity.
The strongest known genetic cause of schizophrenia impairs communication between 2 brain regions and affects working memory, according to a study in mice.
Researchers have identified more than 800 genes that appear to play a role in the male zebra finch's ability to learn elaborate songs from his father. A better understanding of the songbird's communication may lead to insights into human communication.
