Consumers’ Willingness to Buy CRISPR Gene-Edited Tomatoes: Evidence from a Choice Experiment Case Study in Germany

The CRISPR gene-editing (GE) breeding method is used to increase the resilience of high-yielding tomato cultivars against pests and diseases, reducing crop protection requirements. This study investigated consumers’ willingness to buy CRISPR GE tomatoes in a repeated discrete-choice experiment. We observed a strong positive effect of providing information on the CRISPR breeding technology, while the sensory experience of the CRISPR GE tomatoes in a visit to a greenhouse had a rather weak, predominantly negative effect on the participants’ willingness to buy CRISPR GE tomatoes. We found that roughly half of the 32 participants demonstrated constant CRISPR GE tomato choices during the experiments, and these participants were mainly employed as scientists. However, the rest of the participants changed their CRISPR GE tomato choices, with the majority showing an increase in their willingness to buy CRISPR GE tomatoes; these “changers” were dominated by non-scientists. Science communication on CRISPR GE breeding technology should target people with little knowledge about the technology, and consumers of organic tomatoes seem to have more specified, stable preferences regarding the technology. Further, scientific information about the CRISPR GE methodology should preferentially be provided when new technology and information about it are not yet widespread and people have not yet formed a strong opinion about the technology.

FAST principles for preprint feedback

There has been strong interest in preprint commenting and review activities in recent years. Public preprint feedback can bring benefits to authors, readers and others in scholarly communication, however, the level of public commenting on preprints is still low. This is likely due to cultural barriers, such as fear by authors that criticisms on their paper will bias readers, editors and evaluators, and concerns by commenters that posting a public critique on a preprint by a more senior colleague may lead to retribution. In order to help address these cultural barriers and foster positive and constructive participation in public preprint feedback, we have developed a set of 14 principles for creating, responding to, and interpreting preprint feedback. The principles are clustered around four broad themes: Focused, Appropriate, Specific, Transparent (FAST). We describe each of the FAST principles and designate which actors (authors, reviewers and the community) each of the principles applies to. We discuss the possible implementation of the FAST principles by different stakeholders in science communication, and explore what opportunities and challenges lie ahead in the path towards a thriving preprint feedback ecosystem.

Examining science communication on Reddit: From an “Assembled” to a “Disassembling” approach

This study examines science communication within Ask Me Anything sessions hosted by US National Oceanic and Atmospheric Administration scientists on Reddit. In addition to considering a unique social media platform, our work makes an important contribution in revealing the limitations of a traditional approach to studying science communication and modeling an alternative. First, using an “assembled” approach, we qualitatively explore themes in National Oceanic and Atmospheric Administration scientists’ posts and consider how they reflect the goals of “deficit” and “dialogue” models. Second, using a “disassembling” approach, inspired by Davies and Horst and actor-network theory, we more deeply examine our experiences studying the Ask Me Anything sessions. We then demonstrate how this alternative approach identifies “hidden” human and non-human actants that may have shaped science communication as “mediators.” We use these insights to reject the common assumption that science communication on social media occurs solely and directly between scientists and publics.

Mapping mental models of science communication: How academics in Germany, Austria and Switzerland understand and practice science communication

The mental models that individual scholars have of science communication – how it works, what it is supposed to achieve and so on – shape the way these academics actually communicate to the public. But these mental models, and their prevalence among scholars, have rarely been analysed. Drawing on a large-scale, representative web survey of academics at universities in Germany, Austria and Switzerland ( n = 15,778) from 2020, we identify three mental models that are prevalent among scholars, and that correspond to conceptual models found in science communication theory: ‘Public Understanding of Science’, ‘Public Engagement with Science’ and ‘Strategic Science Communication’. The results suggest that the ‘Strategic Science Communication’ model is particularly prevalent among academics in precarious employment and female scholars. Extrinsically motivated academics, that is, those under pressure to win grants, also seem to use science communication more strategically. The ‘Public Engagement’ model is prevalent among older and female scholars, while ‘Public Understanding’ is particularly prevalent among scholars who find their work especially meaningful. Findings also reveal that academics’ mental models largely align with the way they practice science communication.

Scientific Institutions Should Support Inclusive Engagement: Reflections on the AAAS Center for Public Engagement Approach

Scientists’ engagement with society on critical environmental and health issues is essential to reaching positive and equitable long-term outcomes. We argue that stronger institutional support for public engagement is necessary and that inclusive practices should be built into public engagement training and relationships. The American Association for the Advancement of Science (AAAS)’s Center for Public Engagement with Science and Technology provides a model of support for scientists that we believe other scientific institutions can replicate and expand on. This model prioritizes representative and accessible science communication training, resources (e.g., funding and staff and peer support), opportunities to practice engagement, and rewards and incentives for doing engagement. We describe our programs in each of these areas and reflect on how well each builds scientists’ engagement skills and institutional capacity, and whether each embodies and models thoughtful, accessible, and representative engagement. Through these various approaches, the Center communicates to other scientific institutions that engagement by scientists should be valued, celebrated, and supported, and builds capacity for individual scientists to do effective engagement. We argue that these supports can be applied by other scientific institutions to reflect and incorporate society’s diverse needs and concerns, thus truly serving the public and making science and scientific institutions stronger for it.

Incidence of Arterial Hypertension in People With Periodontitis and Characterization of the Oral and Subgingival Microbiome: A Study Protocol

Cardiovascular diseases are the leading cause of morbidity and mortality worldwide. High blood pressure in particular, continues to increase throughout the global population at an increasingly fast pace. The relationship between arterial hypertension and periodontitis has been recently discussed in the context of its origins and implications. Particularly relevant is the role of the periodontal microbiome linked to persistent local and systemic inflammation, along with other risk factors and social determinants of health. The present protocol will investigate/assess the association between periodontal disease and its microbiome on the onset of hypertension, within a cohort from Mexico City. One thousand two hundred twelve participants will be studied during a 60-month period. Studies will include analysis of periodontal conditions, sampling and sequencing of the salivary and subgingival microbiome, interviews on nutritional and lifestyle habits, social determinants of health, blood pressure and anthropometric measurements. Statistical associations and several classic epidemiology and machine learning approaches will be performed to analyze the data. Implications for the generation of public policy—by early public health interventions or epidemiological surveillance approaches—and for the population empowerment—via the establishment of primary prevention recommendations, highlighting the relationship between oral and cardiovascular health—will be considered. This latter set of interventions will be supported by a carefully planned science communication and health promotion strategy. This study has been registered and approved by the Research and Ethics Committee of the School of Dentistry, Universidad Nacional Autónoma de México (CIE/0308/05/2019) and the National Institute of Genomic Medicine (CEI/2020/12). The umbrella cohort was approved by the Institutional Bioethics Committee of the National Institute of Cardiology-Ignacio Chavez (INC-ICh) under code 13-802.
