Brain scans of hundreds of infants suggest that up to 80 percent of those with autism have unusual amounts of cerebrospinal fluid. Researchers are studying how this might contribute to the condition.

These scores — composite measures of a person’s autism-linked common genetic variants — cannot predict an autism diagnosis but could help researchers better understand the condition’s underlying biology.

A massive update to the MSSNG dataset gives qualified researchers ready access to explore autism’s genetic architecture on a cloud-based platform.

The male sex bias in autism may in large part be a product of how common diagnostic tools measure traits in boys versus girls at a single point in time, according to a new study.

Inherited genetic factors for autism influence brain development, new studies of autistic children and their younger siblings reveal.

Increased white-matter maturation tracks with stronger language abilities later in childhood, but the relationship with cortical thickness is less clear.

Integrating genetic analyses into studies of babies’ brain development could help us understand how autism-related genes contribute to autism traits.

In this edition of Null and Noteworthy, researchers open the case on acetaminophen and close it on oxytocin.

So-called ‘baby sibs’ watch adults’ faces just as much as children without autistic siblings do, but they don’t understand spoken language as well.

Connections between the cerebellum and brain networks do not seem to contribute substantially to the emergence of autism traits.
