Smaller babies perform poorer as teens, study finds - BBC

Babies who are smaller than expected at birth tend to have poorer school performances as teenagers, a study has found. More than 92,000 children were followed from infancy to adolescence, all of whom were born at full term, between 37 and 41 weeks pregnant. The researchers at the University of Warwick found that children who weighed less than most babies of the same sex, born at the same stage of pregnancy, tended to achieve lower scores in subjects like mathematics and reading. The differences were still apparent in adolescence, suggesting that the link between size at birth and academic performance persists well beyond early childhood into mid-teens. "For babies born at term, being small for their stage of pregnancy may indicate adverse effects on the brain that affect learning and last into adolescence," Prof Dieter Wolke said. However, he said the long-term effects of being born small may be altered by parenting home stimulation and school support.

With 302 neurons, 200 of them in their heads, hermaphrodite female roundworms reveal surprising sex-specific differences in the nervous system and how these differences influence behavior, reproduction, and aging. Researchers at Northeastern University compared brain activity in male and hermaphroditic Caenorhabditis elegans, a microscopic worm widely used in biological research to understand how sex wires males and female nervous systems differently.
