Child development: The first steps
Because infants born into families with autism are more likely to develop the condition, studying them might lead to ways to diagnose people in the general population earlier.
Birth weight predicts brain size later in life, study says
Heavier newborns have larger brains later in life, and a larger cerebral cortex — the brain region responsible for high-level functions such as consciousness and language. The findings, published 19 November in the Proceedings of the National Academy of Sciences, are the first to assess birth weight’s connection to brain development.

Long-term studies chart autism’s different trajectories
Two new studies that follow the development of children with autism suggest that distinct subgroups of the disorder exist early on, and that the severity of symptoms in most of these children remains stable over time.

ABCD Study omits gender-identity data from latest release
The removal counteracts the goals of the longitudinal study by “pretending that some aspects of adolescent brain development don’t exist,” says sex differences researcher Nicola Grissom.

Neuropeptides reprogram social roles in leafcutter ants
The mechanisms that control the labor roles of ants may also be conserved in naked mole rats, a new study shows.

Perspectives from the field: Opinions in autism research
This collection of Spectrum articles from the past 12 months highlights expert perspectives on autism’s heritability and its link to biological sex, the value of transdiagnostic frameworks, and the field’s future, among other topics.
