Persistent sleeplessness may be far worse than a passing annoyance — gradually unraveling memory and mental sharpness, according to new research. A study published Wednesday in Neurology, the journal of the American Academy of Neurology, identifies a troubling link: Older people who have chronic insomnia appear more likely to experience accelerated aging of the brain. These changes are revealed in both cognitive tests and imaging scans showing the altered structure of the brain. (Eunjung Cha, 9/10)

Pregnancy was a complicated time for Tasha Taylor. The 33-year-old was already managing her bipolar disorder with a psych medication when she got pregnant. Then Taylor learned the prescription drug could hurt her baby. She decided to get off the medication, which led to night terrors. She’d wake up shaking from nightmares of her abusive ex-partner.

In 2023, a group of 16 young Montanans won a much-heralded climate change case that said the state had deprived them of a “clean and healthful environment,” a right enshrined in Montana’s constitution. Their victory in Held v. Montana, later upheld by the state Supreme Court, resounded across the country, showing that young people have a stake in the issue of climate change, advocates say. Yet, state policies to address the causes of climate change in Montana — home to large coal, oil, and natural gas deposits — haven’t changed in the wake of the case. (Robbins, 9/11)
