Autism is more heritable in boys than in girls
If boys have greater inherited liability for autism, the female protective effect may not fully explain the sex difference in prevalence.

Q&A with John Constantino: Solving the biomarker conundrum
Biological factors that reflect autism’s roots may differ from those that influence how severe the condition is. Failure to make a distinction has stymied the search for biomarkers.

International scientific collaboration is more necessary—yet more challenging—than ever
These partnerships accelerate neuroscience by enabling researchers to share resources and expertise, as well as generate more relevant and reproducible results. But new federal funding restrictions in the United States are putting such collaborations in jeopardy.

Oxytocin shapes both mouse mom and pup behavior
Distressed pups emit distinct cries for help, which depend on oxytocin neurons in their hypothalamus.

Sensory gatekeeper drives seizures, autism-like behaviors in mouse model
The new work, in mice missing the autism-linked gene CNTNAP2, suggests a mechanism to help explain the overlap between epilepsy and autism.
