Adolescents spend 1.5 hours daily on smartphones during school

In January, New York Governor Kathy Hochul released a report, titled “More Learning, Less Scrolling,” to prohibit smartphone use during the school day. A team of public health and pediatric researchers, led by Lauren Hale, Ph.D., of Stony Brook University, are working to understand not just screen time use by adolescents but the duration and content of that use, particularly during a typical school day (8:00 AM to 2:30 PM). In a new study that monitored smartphone data, they found that adolescents (aged 13 to 18) spent an average of 1.5 hours each school day on their smartphones.

Scientists find more microplastics in human brains than in kidneys and livers—and levels are rising

Tiny plastic particles may accumulate at higher levels in the human brain than in the kidney and liver, with greater concentrations detected in postmortem samples from 2024 than in those from 2016, suggests a paper published in Nature Medicine. Although the potential implications for human health remain unclear, these findings may highlight a consequence of rising global concentrations of environmental plastics.
