Blood levels of PTEN protein and associated molecules could eventually help diagnose autism and other neurological conditions — and predict their outcomes.

A new machine-learning tool detects eye contact during recorded face-to-face interactions as accurately as expert observers can.

Autistic children who have difficulty managing their emotions are also likely to take medication and need assistance from emergency responders.

A new open-source software package makes it possible to model changes in human and animal behavior over the course of an experiment.

A Hollywood-inspired video tool that captures movement in three dimensions over extended time periods shows that rats lacking the autism-linked gene FMR1 have different grooming patterns than controls do.

Mutations in the autism-linked gene DNMT3A lead to the behaviors and gene-expression changes seen in different neurodevelopmental conditions.

Autistic children may have a harder time catching a ball than non-autistic children do, possibly because they are less able to predict its trajectory.

Children with autism may have a subtly different set of bacteria in their gut than their non-autistic siblings do.
