Confidence is “not just a feeling,” according to neuroscientist Adam Kepecs. Finding the confidence-calculating circuitry in our brains has huge implications for the future of psychiatry. hen someone asks you how confident you are about something, you probably don’t offer an answer like “5” or some other number. You’re more likely to say “very,” or...

Autism’s genetic roots are notoriously tricky to untangle, but researchers are beginning to understand how particular genes may contribute to the disorder. Among those researchers is CSHL’s Ivan Iossifov. or some disorders, genetics explains everything. Hemophilia is a good example: the abnormally profuse bleeding associated with it is neatly accounted for by a defect in...
