A new study found that river flow is reduced by an average of 25% within five years and 40% by 25 years after planting trees, with some rivers disappearing completely in a decade. The type of land where trees are planted determines the impact on local water availability.
A systematic review of existing literature found that leaving school and getting a job leads to a decrease in physical activity, while becoming a mother is linked to increased weight gain.

A new study found that Asian people with dementia are less likely to receive anti-dementia drugs and take them for shorter periods than white peers. Black people with dementia prescribed antipsychotic drugs take them for longer, potentially putting them at greater risk of harm.
