Disrupted connectivity of the brainstem ascending reticular activating system nuclei-left parahippocampal gyrus could reveal mechanisms of delirium following basal ganglia intracerebral hemorrhage

Delirium in critically ill patients with basal ganglia intracerebral hemorrhage shows disrupted connectivity between the brainstem's ascending reticular activating system nuclei and the left parahippocampal gyrus. This disruption is linked to delirium occurrence and may serve as a biomarker for prediction.

As Medicaid work requirements loom, U-M study finds links between coverage, better health and higher employment

A University of Michigan study found that Medicaid coverage is linked to employment gains among low-income adults with serious health problems. Employment nearly doubled among enrollees who experienced improved health, from 26% to 47%. This suggests that Medicaid expansion may actually help individuals participate in the workforce.

Concentration‑controlled doping turns a p‑type polymer into its n‑type counterpart

A South Korean research team has discovered a molecular-level mechanism to switch the charge polarity of organic polymer semiconductors by adjusting the concentration of a single dopant. This enables polymers to exhibit both p-type and n-type characteristics, eliminating the need for separate materials or complex device architectures.
