The app relies on artificial intelligence and could help researchers standardize studies of pupil differences in autistic people and in mouse models of autism.

Preliminary results suggested the treatment is no better than placebo at reducing the severity of core autism traits.

The stubborn lack of treatments for fragile X syndrome — a leading cause of inherited intellectual disability and autism — is spurring researchers to revise clinical trial techniques and revisit old drug candidates.

Brain responses to visual stimuli are smaller and weaker in children with Phelan-McDermid syndrome, an autism-linked genetic condition, than in non-autistic children.

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.

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.

The field of neuroimaging will need to combine two strategies before it can find patterns of brain activity or structure unique to autism, the researchers say.

A test of binocular rivalry may distinguish between autism subtypes and help researchers screen the efficacy of certain drugs.

A novel method to evaluate the strength of the evidence linking autism to specific genes could reveal which ones are most useful to screen for.

A mobile phone app that tracks a toddler’s gaze as she watches short videos can distinguish between children who later receive an autism diagnosis and those who do not according to a new study.
