Many people with autism have difficulty falling and staying asleep, but there may be ways to help them.

Sleeping zebrafish show two patterns of neuronal activity that are analogous to those in people.

Researchers have engineered two generations of monkeys with mutations in SHANK3, a top autism gene. The first generation shows traits reminiscent of the condition.

Autistic children may be more likely than their unaffected siblings to carry mutations in genes linked to sleep.

Depression may show up in children with autism in an unusual way — most commonly as insomnia and restlessness.

Heightened sensory perception in toddlers with autism may predict sleep problems at around age 7.

Scientists have created five monkey clones, all carrying an edit to a specific gene.
