Father’s advanced age feeds autism risk
Are older fathers more likely to have children with autism? A series of epidemiological studies is giving credence to the idea, suggesting that, with age, sperm may accumulate damage that increases risk in the next generation.
Sense of ‘self’ impaired in autism
People with autism struggle to see their own role in social situations. That's the conclusion from the first study to scan individualsʼ brains while they interact with another person - a technique that could lead to a diagnostic tool.

Autism-linked variants converge on two molecular patterns in mouse brains
Gene activity across 17 autism mouse models occurs in either of two opposing transcriptomic states, supporting the idea that diverse genetic changes may converge on a few recurring biological patterns.
