A Tampa clinic goes rogue with fecal transplants, autism’s genetic ancestry traces to our deep past, and the U.S. Supreme Court revives the travel ban.

Large autism-linked mutations tend to be inherited in families with a history of the condition. By contrast, they often arise spontaneously in families with a single affected person.

The specter of the ‘refrigerator mother’ theory continues to haunt the history of autism. New information puts Kanner’s observations of parents into context.

Researchers are launching a new project that aims to collect genetic information from 50,000 people with autism, along with their relatives.

A study of more than 2,500 families that have at least one child with autism has found three factors that predict autism symptoms in an unaffected sibling.

Identifying the factors that protect girls from autism may help us understand and possibly treat the disorder.

Many children with autism have gastrointestinal problems, seizures and sleep disorders. A new study suggests that these seemingly disparate conditions are interconnected and may lead to the children’s behavioral issues.

Children whose older sisters are on the spectrum are at higher risk for autism than are those with affected older brothers, a new study suggests. Younger brothers of children with autism are at greater risk than younger sisters.

Through a clever combination of sequencing genes and tracing family ties, Icelandic researchers have gathered genomic information for nearly one-third of their nation’s population.  

Some newborn horses have features of autism, and researchers argue over who first described the disorder.
