A 3D model of a human embryo reveals the biological processes that unfold in early development.

Being anemic while pregnant may increase a woman’s chance of having a child with intellectual disability, autism or attention deficit hyperactivity disorder.

Researchers have created a microscopic particle that traps immune molecules found in a woman that are linked to autism in her child.

The more words autistic children hear as infants — and the more verbal interactions they have with their caregivers — the better their language skills at age 2.

Adults with autism are nearly 50 percent more likely to die in the hospital than their typical peers.

About 81 percent of autism risk comes from inherited genetic factors, according to an analysis of more than 2 million children from five countries.

A cache of about 100 brain organoids grown from human cells is expected to launch into orbit this month.

Many scientists have pointed out possible errors of analysis and interpretation in a high-profile study that suggested microbes can ease autism-like behaviors in mice.

Mice colonized with gut microbes from some autistic boys show behaviors like those of the boys.

Autistic people have unusual responses to ‘affective touch,’ which conveys social and emotional information. Their responses may reveal how autism begins.
