People who follow “new right” media outlets are more than twice as likely to be vaccine-hesitant compared to those who never engage with those outlets, a new Johns Hopkins University study finds.

Researchers surveyed nearly 3,000 adults in 2025, as measles cases hit record highs in the United States, asking participants about their sources for news and health information and how they felt about the measles-mumps-rubella, or MMR, vaccine. The findings revealed how specific media habits are strongly associated with attitudes toward vaccines.

Cheese3D—a new platform developed by Helen Hou, Kyle Daruwalla, and Irene Nozal Martin—enables scientists to capture and analyze high-speed 3D recordings of a mouse’s entire face. The system has now been used to measure anesthesia depth and should have additional applications in health, disease, and development.
