The research carried out with the CNPq Research Groups Directory rescued the research groups in Environmental Communication in Brazil, which were categorized based on numerous factors (date of foundation, constitution, institutional links, lines of research and profile of the group leaders , its training and production in the area). The data obtained in the investigation, of a primarily quantitative nature, highlighted the importance of these groups in the production and dissemination of qualified information, allowing us to conclude that they contribute to subsidizing the construction of public policies, as well as to the training of teachers, researchers and professionals in the environmental field.

In this article, we conducted a comprehensive survey of the publications from "Médicos por la Verdad" (Doctors for the Truth), one of the main anti-vaccine groups in Latin America, on the social media platform Twitter during the COVID-19 pandemic. We categorized their types of reasoning and the content of their messages, and we showed that the existing proposals for the analysis of anti-scientific discourses cannot be applied to this particular case. Consequently, we propose a new categorization and its focused application using tools available for science communicators on one hand, and the non-specialized public on the other.

The main objective of this work is to identify the communicative elements essential to generating effective communication of health and its relationship with health policies, actions, and strategies. To do this, based on a case study, interviews were carried out with doctors and researchers in Type 2 Diabetes Mellitus in Mexico. We realized an analysis of how medical and scientific communities relate to society, from their participation in spaces within scientific communities and openness to the dialogues and challenges they face. Finally, we proposed communicative elements to establish effective health communication.

Se busca conformar un panorama general de la comunicación pública de la arqueología en México, específicamente desde experiencias en uno de sus estados costeros, a través de un diagnóstico generado desde una revisión bibliográfica y mediática, así como con entrevistas a arqueólogos y arqueólogas. Lo anterior a partir de una conceptualización desde la apropiación social de la ciencia, además de una postura pluralista que invita a considerar las particularidades de las disciplinas científico sociales dentro de los estudios en comunicación pública de la ciencia y la tecnología.

This paper shares advances of an ongoing research that investigates the meanings in relation to the communication of science and technology (CPCyT) by researchers at the National University of Misiones. We are interested in reflecting on the central role of social communication in the production and communication of scientific and technological knowledge. Our study investigates the formats and media used by researchers to communicate the results of their productions. In this article, we will focus on identifying, describing and analysing proposed CPCyT products in projects at the mentioned University during 2018-2020.

We investigated main points about Alzheimer's disease in Brazilian science blogs. Main subjects were explanations about the disease, besides fighting and preventing it. More scientific communication activities on the subject are recommended.

The article presents the results of an exploratory study conducted through the application of an online questionnaire to Twitter users close to three active scientific dissemination networks during the pandemic in Ecuador (Kuna Ecuador, Red Ecuatoriana de Mujeres Científicas, and Red DivulgaCiencia). The main objective is to propose specific strategies for the use of the digital platform to disseminate science and persuade public opinion, starting with an understanding of the perception regarding the concepts used to refer to the communicative interaction between the scientific community and society.

This study analysed news stories from the newspaper Folha de S.Paulo in three time periods during the first year of the pandemic in Brazil. Through content analysis, in the context of a theoretical framework that includes elements of public communication of science, community health and critical epidemiology, we sought to identify trends and changes in the topics reported and concluded that there is a change of focus with the evolution of the pandemic and limitations are observed to address scientific issues.

Through discourse analysis, the human-technology relationship in the Marvel Cinematic Universe is explored and the construction of a scenario based on apparently rational rules is discovered, where science, magic and mythology seem to be the same thing. The technology is presented as an invasion to the human, who is forced to adapt to understand the technology that invaded him. Finally, when the human learns not to question the invasion and to use technology to protect and improve himself, the new technology (previously an invader) and the human, integrate until they merge.

Some research and surveys conducted in Mexico show that there is still a lack of knowledge on how to increase public engagement with science. Because of this, a study was carried out using conceptual frameworks of Science Communication for a Centre for Science Communication. Three axes are outlined: modalities WITH, FOR and BETWEEN the public; public engagement with science and science capital. At the same time, programmes are proposed to carry out activities and encourage awareness, interest, intrinsic motivation, enjoyment and understanding in order to contribute to scientific culture.
