De-Problematizing 'GMOs': Suggestions for Communicating about Genetic Engineering

Visualizing science: The impact of infographics on free recall, elaboration, and attitude change for genetically modified foods news

Within the theoretical frameworks of the dual coding theory, this study examined how the implementation of infographics would influence audiences' cognitive responses to science news reporting topics of genetically modified food and bioengineering. A total of 280 participants were randomly assigned to view news articles that report genetically modified food information presented via infographics or text. Findings showed that the participants recalled more information, elaborated more message-relevant thoughts, and had more favorable attitude changes toward the genetically modified foods when science news content is presented in infographics compared with text. Theoretical and practical implications are discussed herein.

Establishing a baseline of science communication skills in an undergraduate environmental science course

BACKGROUND

Seminal reports, based on recommendations by educators, scientists, and in collaboration with students, have called for undergraduate curricula to engage students in some of the same practices as scientists-one of which is communicating science with a general, non-scientific audience (SciComm). Unfortunately, very little research has focused on helping students develop these skills. An important early step in creating effective and efficient curricula is understanding what baseline skills students have prior to instruction. Here, we used the Essential Elements for Effective Science Communication (EEES) framework to survey the SciComm skills of students in an environmental science course in which they had little SciComm training.

RESULTS

Our analyses revealed that, despite not being given the framework, students included several of the 13 elements, especially those which were explicitly asked for in the assignment instructions. Students commonly targeted broad audiences composed of interested adults, aimed to increase the knowledge and awareness of their audience, and planned and executed remote projects using print on social media. Additionally, students demonstrated flexibility in their skills by slightly differing their choices depending on the context of the assignment, such as creating more engaging content than they had planned for.

CONCLUSIONS

The students exhibited several key baseline skills, even though they had minimal training on the best practices of SciComm; however, more support is required to help students become better communicators, and more work in different contexts may be beneficial to acquire additional perspectives on SciComm skills among a variety of science students. The few elements that were not well highlighted in the students' projects may not have been as intuitive to novice communicators. Thus, we provide recommendations for how educators can help their undergraduate science students develop valuable, prescribed SciComm skills. Some of these recommendations include helping students determine the right audience for their communication project, providing opportunities for students to try multiple media types, determining the type of language that is appropriate for the audience, and encouraging students to aim for a mix of communication objectives. With this guidance, educators can better prepare their students to become a more open and communicative generation of scientists and citizens.

Promoting Ethically Responsible Use of Agricultural Biotechnology

Growing global demands for food, bioenergy, and specialty products, along with the threat posed by various environmental changes, present substantial challenges for agricultural production. Agricultural biotechnology offers a promising avenue for meeting these challenges; however, ethical and sociocultural concerns must first be addressed, to ensure widespread public trust and uptake. To be effective, we need to develop solutions that are ethically responsible, socially responsive, relevant to people of different cultural and social backgrounds, and conveyed to the public in a convincing and straightforward manner. Here, we highlight how ethical approaches, principled decision-making strategies, citizen-stakeholder participation, effective science communication, and bioethics education should be used to guide responsible use of agricultural biotechnology.

Prospects for potato genome editing to engineer resistance against viruses and cold-induced sweetening

Crop improvement through transgenic technologies is commonly tagged with GMO (genetically-modified-organisms) where the presence of transgene becomes a big question for the society and the legislation authorities. However, new plant breeding techniques like CRISPR/Cas9 system [clustered regularly interspaced palindromic repeats (CRISPR)-associated 9] can overcome these limitations through transgene-free products. Potato (Solanum tuberosum L.) being a major food crop has the potential to feed the rising world population. Unfortunately, the cultivated potato suffers considerable production losses due to several pre- and post-harvest stresses such as plant viruses (majorly RNA viruses) and cold-induced sweetening (CIS; the conversion of sucrose to glucose and fructose inside cell vacuole). A number of strategies, ranging from crop breeding to genetic engineering, have been employed so far in potato for trait improvement. Recently, new breeding techniques have been utilized to knock-out potato genes/factors like eukaryotic translation initiation factors [elF4E and isoform elF(iso)4E)], that interact with viruses to assist viral infection, and vacuolar invertase, a core enzyme in CIS. In this context, CRISPR technology is predicted to reduce the cost of potato production and is likely to pass through the regulatory process being marker and transgene-free. The current review summarizes the potential application of the CRISPR/Cas9 system for traits improvement in potato. Moreover, the prospects for engineering resistance against potato fungal pathogens and current limitations/challenges are discussed.

Genebank genomics bridges the gap between the conservation of crop diversity and plant breeding

Genebanks have the long-term mission of preserving plant genetic resources as an agricultural legacy for future crop improvement. Operating procedures for seed storage and plant propagation have been in place for decades, but there is a lack of effective means for the discovery and transfer of beneficial alleles from landraces and wild relatives into modern varieties. Here, we review the prospects of using molecular passport data derived from genomic sequence information as a universal monitoring tool at the single-plant level within and between genebanks. Together with recent advances in breeding methodologies, the transformation of genebanks into bio-digital resource centers will facilitate the selection of useful genetic variation and its use in breeding programs, thus providing easy access to past crop diversity. We propose linking catalogs of natural genetic variation and enquiries into biological mechanisms of plant performance as a long-term joint research goal of genebanks, plant geneticists and breeders.

Edit at will: Genotype independent plant transformation in the era of advanced genomics and genome editing

The combination of advanced genomics, genome editing and plant transformation biology presents a powerful platform for basic plant research and crop improvement. Together these advances provide the tools to identify genes as targets for direct editing as single base pair changes, deletions, insertions and site specific homologous recombination. Recent breakthrough technologies using morphogenic regulators in plant transformation creates the ability to introduce reagents specific toward their identified targets and recover stably transformed and/or edited plants which are genotype independent. These technologies enable the possibility to alter a trait in any variety, without genetic disruption which would require subsequent extensive breeding, but rather to deliver the same variety with one trait changed. Regulatory issues regarding this technology will predicate how broadly these technologies will be implemented. In addition, education will play a crucial role for positive public acceptance. Taken together these technologies comprise a platform for advanced breeding which is an imperative for future world food security.

The art of talking about science: beginning to teach physiology students how to communicate with nonscientists

The ability to clearly disseminate scientific knowledge is a skill that is necessary for any undergraduate student within the sciences. Traditionally, this is accomplished through the instruction of scientific presentation or writing with a focus on peer-to-peer communication at the expense of teaching communication aimed at a nonscientific audience. One of the ramifications of focusing on peer-to-peer communication has presented itself as an apprehension toward scientific knowledge within the general populace. This apprehension can be seen in a variety of venues, including the traditional media, popular culture, and education, which generally paint scientists as aloof and with an inability to discuss scientific issues to anyone other than other scientists. This paper describes a curriculum designed to teach Introduction to Anatomy and Physiology students the tools necessary for communicating complex concepts that were covered during the semester using approachable language. Students were assessed on their word usage in associated writing activities, the student's ability to reduce complexity of their statements, and performance in an informal scientific presentation to a lay audience. Results showed that this pedagogical approach has increased students' ability to reduce the complexity of their language in both a written and oral format. This, in turn, led to evaluators reporting greater levels of understanding of the topic presented following the presentation.

Engaging the Senses, Understanding Publics: Research Methods, Science Engagement, and Synthetic Biology

Scientists and government actors often fear a 'public rejection' of biotechnology, especially regarding genetic modification. Through a research project aimed at engaging people's senses, we support an alternative way for scientists to consider non-scientists in their research.
