Early education and cognitive enrichment programs boosted the adult earnings of impoverished Jamaicans by 25%, according to the first long-term study of this type in a developing country.

The language and cognitive difficulties often seen in autism may be caused in part by an overly connected frontal lobe within the brain, says a new study of children published in Science Translational Medicine.

The research points to a gene called CNTNAP2 as responsible for wiring neurons in the front of the brain. If carrying different versions of CNTNAP2 is found to be a consistent predictor of language difficulties, the findings may help researchers design targeted therapies to assist the brain toward a path of more normative development early on.
