A re-analysis of data yields an increased estimate for the genetic contribution to autism, how the environment might contribute to autism is hard to pin down, and students on the spectrum describe the benefits of using technology at school.

A small study suggests that baby teeth may afford a way to explore environmental risk factors for autism.

Genes are bigger contributors to autism features than are environmental factors, according to a study of nearly 39,000 twins.

The evidence linking autism and maternal infections grows, special neuron recipes are in development, a CRISPR pioneer envisions unicorns, and 23andMe delivers empathy data.

Women who have raised a child with autism may be well-positioned to spot subtle signs of the condition in their grandchildren. A new study puts their powers to good use.

Identical twins, who have virtually the same genetic material, show highly similar patterns of eye movements when looking at faces, suggesting that social gaze is hardwired.

Studying large numbers of fraternal and identical twins may help tease apart genetic and environmental contributors to autism.

A variant in a gene that regulates immune responses is more common in children with autism than in those without this disorder.

Researchers in Sweden are assembling a large group of identical twin pairs, with only one twin in each pair having autism.

A questionnaire that clinicians can administer in 20 minutes, either in person, by phone or online, correctly distinguishes children with autism from those without the disorder 86 percent of the time.
