Scientists release a list of all randomized controlled trials of autism treatments, China establishes a brain center for an ambitious new project, and people around the world march for science again.

Modified versions of molecules found in fireflies make brain cells glow so brightly they are visible from outside the body.

Some genes associated with autism may influence the thickness of the cerebral cortex, the brain’s outer layer.

A large dataset that catalogs the features of many brain conditions could transform the quest for biomarkers of autism.

Microglia come into frequent contact with synapses, the connections between neurons, but they appear to nibble on them rather than engulf and digest them.

Integrating human-specific genetic elements into mice may provide a permissive, ‘humanized’ environment for studying autism.

Examining the teenage years presents a major opportunity for understanding and treating autism.

Autism is not associated with ultrasound frequency or duration, maternal age and education affect autism odds, and people on the spectrum benefit from their ‘special interests.’

Autism and attention deficit hyperactivity disorder often coincide, but the search for common biological roots has turned up conflicting evidence.

Common genetics may help forge social ties, a nonspeaking woman with autism hosts “The Late Show,” and the mix of bacteria in the gut may relate to brain structure.
