Facebook is using artificial intelligence to spot potentially suicidal members of its community. “The social network has developed algorithms that spot warning signs in users' posts and the comments their friends leave in response,” BBC News reports. “After confirmation by Facebook's human review team, the company contacts those thought to be at risk of self-harm to suggest ways they can seek help.”

As part of its broad hardware ambitions, Snap has reportedly tested a drone. “A drone could help Snap’s users take overhead videos and photographs, and then feed that visual data to the company,” The New York Times, writes. That said, “It is unclear when or if Snap’s drone would become available to consumers.”
