New artificial intelligence, detailed in a paper published today in Nature Human Behavior, has helped researchers to teach machines to spot suicidal tendencies and help identify those at risk, per MIT Technology Review.

Why it matters: The success of the study reveals the great potential there is for AI to aid in psychiatry, in addition to the medical developments that AI has already contributed to, such as in detecting tumors and predicting depressive disorders.

Details of the study, as detailed by MIT Technology Review:

  • Researchers analyzed 34 young adults, even split between suicidal participants and a control group. Each person was sent through a functional magnetic resonance imaging (fMRI) and given three lists of 10 words all relating to suicide (such as "death" or "distressed"), positive effects (such as "kindness" or "innocence"), or negative effects (such as "evil" or "guilty").
  • They studied five specific brain locations that were determined to be the best marks to distinguish the suicidal patients from the controls. Using those locations and words, the machine identified 15 of the 17 patients with suicidal behavior and 16 of 17 control subjects.
  • The suicidal participants were then split into two groups, those who had attempted suicide and those who hadn't, and the machine was trained to distinguish the differences.

Former President Bill Clinton was discharged from the University of California, Irvine Medical Center on Sunday, nearly a week after he was admitted for a non-COVID-related infection, according to his spokesperson Angel Ureña.

What they're saying: "His fever and white blood cell count are normalized and he will return home to New York to finish his course of antibiotics," wrote Dr. Alpesh Amin, who has been overseeing the team of doctors treating Clinton. "On behalf of everyone at UC Irvine Medical Center, we were honored to have treated him and will continue to monitor his progress."

Worth noting: Clinton had a urinary tract infection that spread to his bloodstream, per CNN.

  • The California-based medical team had been administering IV antibiotics and fluids, and was in constant communication with Clinton's New York team, including his cardiologist, according to the former president's physicians.
  • President Biden spoke by phone with Clinton on Friday to see how he was doing, and the catch-up included a discussion of recent politics.

Children were among up to 17 American Christian missionaries and their relatives kidnapped by a gang in Haiti on Saturday, the New York Times first reported.

Details: The missionaries had just left an orphanage and were traveling by bus to the airport to "drop off some members" and were due to travel to another destination when the gang struck in Port-au-Prince, Haitian security officials said, per the NYT.
