This study describes US-based physicians' online public communication practices, particularly on the social media platform Twitter/X, during the COVID-19 pandemic. We draw on 28 semi-structured interviews to examine how they responded to the unique COVID-19 context with respect to each of the four features of post-normal science (PNS): facts uncertain, values in dispute, stakes high, and decisions urgent. Our analysis reveals that the pandemic shifted what, why, and how physicians used the platform, and with whom they aimed to communicate. We discuss the implications of these changes in their online communication habits, discourses, and representations around social media as a reaction to the context of PNS brought about by the pandemic.

Through 19 interviews with scientists, this study examines scientists' use of media logic and their relationships with journalists using research as the focal point. The authors identified that the scientists shared a basic understanding of media logic classified in three patterns. Two patterns were previously identified by Olesk: 1) adaption (ability to explain research in a simple, engaging fashion but with a reactive approach to journalist interaction) and 2) adoption (proactively create and manage media interactions for strategic aims through a more active use of media logic). The other emerged as a new, third pattern, affiliation (enthusiastic contributors to journalists' production practices and desire to engage in public outreach).
