Researchers find a surprising link between certain pollutants and reduced autism risk, the world welcomes — and fears — the first primate clones, and new U.S. clinical trial rules reverberate globally.

Black parents are less likely than white parents to report concerns about autism features in their children, human brain organoids in rodent bodies raise ethical concerns, and science graduate programs in the United States have few American students.

Two new gadgets join the gene-editing toolbox, many children with autism get smarter with age, and a survey points to a research reset for Autism Speaks.

People with autism who have rare, damaging mutations tend to have low scores on intelligence tests.

Children with ‘severe autism’ are the most in need of help, yet the most overlooked in research. A new initiative is making them the primary focus.

Children with mutations in a gene called DYRK1A, a leading autism candidate, have a distinct set of features, including intellectual disability, speech delay, motor problems and a small head.

A new database details the genetic mutations associated with Phelan-McDermid syndrome, along with the behavioral outcomes of people with those mutations.

Taking prenatal multivitamins may reduce the risk of having a child who has autism with intellectual disability, another vaccine-autism link study is being retracted, and schizophrenia sometimes accompanies autism.

An epilepsy drug may prevent seizures in infants with tuberous sclerosis and alleviate their autism features, says Martina Bebin.

People with autism aren’t easily surprised, the social camouflage some girls and women with autism use may preclude diagnosis, and autism-related genes are rooted deep in human ancestry.
