A new computational method sifts true mutations from spurious ones in a single cell’s genome.

A new magnetic resonance imaging machine has the power to reveal the brain’s structure and activity at unprecedented resolution.

Two imaging techniques together reveal architectural features of the brains of preterm infants.

A new parent questionnaire is the first test designed to gauge anxiety in children with autism.

An evaluation of 11 tests of social skills has identified 8 that give credible results in autistic adults.

A pair of maps that depict variation in the human genome may help reveal the genetic roots of autism.

The largest-yet attempt to characterize the global diversity of the human microbiome — the population of microbes that live in our bodies — has found 4,930 species, 77 percent of which were previously unknown.

Autism BrainNet, a repository of postmortem brains, has new tissue from more than 150 brains, including 59 from people with confirmed or possible autism.
