Two researchers balk at talk that Wi-Fi and autism are linked, changes in an autism risk gene are tied to obsessive-compulsive traits in three species, and scientists plan to conduct a census of all of the brain’s cell types.

A gene called TRIO may be a hotbed for autism mutations, an international collaboration focuses on the whole brain and one behavior, and Autism Speaks cuts grant spending.

A new technique allows researchers to generate brain cells called astrocytes and maintain them in culture as they mature.

Some genes linked to autism regulate the production of proteins at neuronal junctions, suggesting that disrupted protein synthesis contributes to the condition.

Monkeys missing the gene SHANK3 have too few neurons in the prefrontal cortex, a brain region involved in planning and social behavior.

Music therapy proves ineffective for autism, brain structures differ with 16p11.2 duplications and deletions, and mice missing NLGN3 may influence the sociability of their littermates.

A large study of minute mutations in people with developmental conditions, including autism, has uncovered 200 potential risk genes.

A drug used to treat type 2 diabetes reverses behavioral and brain abnormalities in a mouse model of fragile X syndrome.

RNA segments that control when and where genes are expressed may be involved in autism.

After a decade of fast-paced discovery, researchers are racing toward bigger datasets, more genes and a deeper understanding of the biology of autism.
