New research suggests that people who live in rural areas may be benefiting from telehealth as a modality for substance use disorder treatment to a greater extent than their urban counterparts. Meanwhile, despite accounting for the vast majority of substance use disorder services, people covered by Medicaid managed care are less likely to use telehealth compared with their counterparts who have Medicare Advantage or are commercially insured.

Researchers have generated the first dataset of water flow beneath the entire Antarctic Ice Sheet, which will lead to more accurate projections of sea level rise. 

The team from the University of Waterloo modeled Antarctica’s subglacial environment. The dataset represents the researchers’ best approximation of what the water flow underneath the ice sheet might currently look like. The results include numerous subglacial lakes developing below ice streams in both East and West Antarctica, and an extensive network of subglacial water channels that discharge large fluxes of water under many major glaciers. 

A research team has found that drugs being sold as fentanyl contain high amounts of the industrial chemical bis(2,2,6,6-tetramethyl-4-piperidyl) sebacate, or BTMPS. This new substance of concern emerged in the illicit drug supply nearly simultaneously in multiple U.S. locations from coast-to-coast.
