High blood pressure or abnormal bleeding during pregnancy, as well as complications such as cesarean delivery or preterm birth, may all increase the risk of autism, two new studies suggest.
The absence of several interacting genes underlies the developmental problems seen in people missing a segment of chromosome 16, a new study in fruit flies suggests.
Boosting levels of the chemical messenger serotonin makes mice that model autism more social, according to a study published today in Nature.

Blocking an enzyme called ERK prevents some unusual behaviors and brain structure in mice missing a segment of chromosome 16.
The brain’s system for sensing pleasure and reward shows unusual activation patterns in people with autism, according to an analysis of 13 imaging studies.
More than half of people on the spectrum have four or more other conditions. The types of co-occurring conditions and how they manifest varies from one autistic person to the next.
Scientists have for the first time successfully delivered the gene-editing tool CRISPR into mouse brains and altered their behavior.
Rats with a mutation in CACNA1C, a gene linked to autism, make fewer happy squeaks while playing than controls do, and ignore other rats’ requests to play, a new study suggests.
Mice with a mutation in a top autism gene called SHANK3 have altered levels of certain gut bacteria, a new study shows.
People with mutations in SHANK3 have intellectual disability and other features of Phelan-McDermid syndrome, the condition most closely associated with this gene.
Girls with autism traits have fewer problems with social communication than boys do early on, but their skills worsen by adolescence, a new study suggests.
The brains of people with autism show a variety of structural differences from those of controls, according to a large imaging study.
Girls with an autism diagnosis have more severe impairments in social communication than boys with the diagnosis, according to a large population-based study.
Children with autism often have trouble understanding others’ thoughts, and some may compensate for this by creating scripts and using other learned strategies to navigate social si
