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.

Modern AI is simply no match for the complexity likely required for harboring consciousness, says Jaan Aru
He argues that our brain’s computations are of a completely different nature than any artificial intelligence because they take place across many spatial and temporal scales and are inextricably entwined with biological materials.
