As toddlers age into the preschool years, their dependency on their parents usually begins to ebb. However, a new study led by Penn State researchers has revealed that physically or psychologically aggressive parenting, such as spanking or shouting, can disrupt this pattern to the detriment of both child and mother, with the child requiring more external regulation, rather than less, as they age.  

A University of California, Riverside preclinical study is shedding light on a long-observed but poorly understood phenomenon: chronic cannabis users tend to have lower body weight and a reduced risk of developing type 2 diabetes, despite the drug’s well-known tendency to increase appetite.
