Jeff Brainard, Associate News Editor at Science, discusses the public's mixed understanding of preprints, particularly during the COVID-19 pandemic. He highlights the need for skepticism in media narratives around these studies. Edward Hurme, a postdoctoral fellow at the Max Planck Institute, shares insights on tracking bat migrations using innovative tagging technology. He details the challenges of monitoring these nocturnal creatures as they traverse long distances and reveals fascinating data about their flight patterns and the impact of environmental changes.
The public's misunderstanding of preprints necessitates improved media communication, as many struggle to grasp their significance and reliability.
Recent advancements in tagging technology have enhanced our understanding of bat migration, revealing how environmental factors influence their migratory patterns.

Public Perception and Coverage of Preprints
The discussion centers on how the public perceives preprint publications and the role of media in reporting them, particularly during the COVID-19 pandemic. Preprints, which are manuscripts that have not undergone peer review, saw increased scrutiny as their importance grew in disseminating urgent scientific findings. Journalists grappled with how to report these findings, balancing the need for timely information with concerns about their reliability. Research indicated that many readers struggle to understand what a preprint is, with only about a third of survey respondents correctly defining the term, leading to calls for better context and disclaimers in news reporting.
Challenges and Innovations in Bat Tracking
Tracking bat migration was historically difficult due to the nocturnal nature of these animals and the logistical challenges of following them. Researchers have recently utilized innovative tagging technology, specifically the Icarus Tiny Fox Bat Tags, which transmit data remotely and reduce the need for manual data retrieval. This advancement allows scientists to monitor 100 tagged bats over extended periods, gathering crucial data on their locations and behaviors during migration. Insights revealed how environmental factors, like wind and temperature, significantly influence migration patterns, demonstrating the bats' adaptability to changing conditions.
Implications for Research and Conservation
The research findings highlight the relationship between bat migration and environmental conditions, suggesting bats may migrate in response to storm fronts. Early and late migrating bats exhibit different energy expenditures, demonstrating trade-offs in their migratory strategies. Furthermore, the study emphasizes the necessity for greater collaboration between researchers and conservation efforts, particularly concerning the impact of human infrastructure on bat populations. With wind turbines posing substantial risks, understanding migration patterns can inform strategies to mitigate threats and enhance the conservation of these species.
First up this week, as preprint publications ramped up during the beginning of the COVID-19 pandemic, so did media attention for these pre–peer-review results. But what do the readers of news reports based on preprints know about them? Associate News Editor Jeff Brainard joins host Sarah Crespi to discuss studies that look at the public perception of preprints in the news and how to inject skepticism into stories about them.
Next, placing tiny tags on bats to follow them across central Europe. Former Science intern Edward Hurme—now a postdoctoral fellow in the Department of Migration at the Max Planck Institute of Animal Behavior—revisits the podcast after 13 years. He discusses the difficulty of tracking bats as they fly long distances at night and what new tagging technology is revealing about their migration patterns.
