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.

Mouse pups exposed to an immune response in the womb show autism-like behaviors and altered gene expression in brain cells called microglia.

Mutations in the Rett syndrome gene MECP2 have different effects on subtypes of neurons.

New initiatives aim to increase brain donations for autism research and maximize what scientists can learn from these precious specimens.

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.

Delivering a fragment of the Rett syndrome gene MECP2 into neurons eases features of the syndrome in a mouse model.

A re-analysis of data yields an increased estimate for the genetic contribution to autism, how the environment might contribute to autism is hard to pin down, and students on the spectrum describe the benefits of using technology at school.

A new technique classifies neurons by surveying chemical tags that turn genes on or off on the neurons’ DNA.

A monkey study suggests facial recognition is not innate, a puzzle piece symbol carries negative connotations, and scientists are using a federal law to snoop on colleagues.

The landscape of chemical modifications on the DNA of people with autism could reveal clues to the condition and lead to treatments.
