A study covered in STAT's Morning Rounds newsletter finds that purer fentanyl will not solve the U.S. overdose death crisis. The result pushes back on the idea that increasing fentanyl purity, by itself, could reduce fatal overdoses.
The same newsletter also carries cautious optimism about the ongoing Ebola outbreak and notes that the FDA is still stymied by DOGE cuts. Because this is a single-source roundup, there are no conflicting reports to compare; it presents these as the latest health updates from the news organization.
