The same genetic factors may underlie both autism and autistic people’s tendency to have sleep problems, such as insomnia.

The double empathy theory challenges the idea that social difficulties are specific to autism and suggests that problems arise from a mismatch in perspective between autistic and non-autistic people.

A mutation in the autism-linked gene SHANK3 changes how neurons encode information about social agency in mice.

Researchers can roughly project what autistic children’s lives will look like years down the road. But how good is their crystal ball — and what are its benefits?

How autistic people look at a face may be linked more to alexithymia, a condition marked by difficulties recognizing one’s own emotions, than to autism.

After a study revised a popular measure for alexithymia, it was pulled for copyright infringement because the authors did not pay a $40 fee or obtain permission to use the measure.

The high levels of serotonin seen in the blood of some autistic people have confounded scientists for more than half a century. Despite so little progress, some researchers refuse to give up.

An animated mouse reenacts common behavioral experiments and can be used to train algorithms that automatically track lab animals’ movements.

The recognition of autism independently at different times and across different cultures shows the condition has clear boundaries, despite considerable heterogeneity.

Researchers have defined a change in score on a popular autism rating scale that signifies a meaningful improvement in core traits. The measure could help scientists assess the effectiveness of autism treatments in clinical trials.
