Overall self-harm rate among young people in California more than doubled, from 191 to 453 per 100,000 person-years — a public health metric used to track the incidence of disease or other life events. Researchers also found that nearly 73% of adolescents with treated self-harm injuries in California were girls.

White girls between 15 and 19 years old had the highest rate of self-harm in 2005 and have seen rates steadily increase since then. But multiracial adolescents have seen an increase of approximately 75% in self-harm rates since 2016. By 2021, self-harm rates were highest among multiracial teen girls, followed by those who are white.

A groundbreaking study from East China Normal University has leveraged AI to analyze classroom teaching patterns across China, revealing that teacher-centered instruction still dominates. This research utilizes a sophisticated AI-powered classroom intelligent analysis system to assess 1,008 recorded Chinese language classes spanning nine grade levels. Usage of AI enables effective systematic analysis of large volumes of classroom data, reducing time and human intervention.
