This article presents four short examples of new insights into suicidal acts and innovative treatments. These include the results of cognitive neuroscience studies that have identified hypersensitivity to rejection, exclusion, and injustice signals in suicide attempters, as well as persisting trend for risky choices and insufficient cognitive control.

In addition, artificial intelligence is a source of hope to account for the etiological and phenotypic complexity of suicidal behavior, and to establish more precise algorithms of medical decision-making. Ethical issues are raised at the same time.
