A woman’s suicide risk may be influenced by the suicidal intention of her female first degree relatives, with sex specific effects of a shared familial environment and possibly other social factors having a key role, finds a large population study published in the online journal BMJ Mental Health. While genetic factors strongly influence a person’s risk of suicide, they don’t fully explain the observed sex differences in suicidal behaviours, whereby males die by suicide more often than females, but females attempt suicide around twice as often as males, say the researchers.

Learning French, reading the latest Andy Weir novel, hanging out with friends for St. Patrick’s Day — language is central to all these everyday activities. Seemingly effortless from childhood, language, it turns out, is quite complex, not constrained to one set of genes or one region in the brain. Cognitive neuroscientists are now using a diverse arsenal of tools, including novel genetic analyses and AI, to gain insights into both healthy and disordered communication across individuals, as will be presented at the annual meeting of the Cognitive Neuroscience Society (CNS) in Vancouver, British Columbia.
