The role of education and communication is crucial to achieving the transition toward a circular economy (CE). Achieving cognitive, attitude and behavioural changes in the consumer and general population is a very complex process which requires mature scientific knowledge created by specialists. The current study aims to evaluate the degree of maturity of research on CE and bioenergy carried out from the areas of education and communication which are published in scientific literature between 2009 and 2019. The object of study have been scarcely approached from epistemological and methodological point of view, which is the novelty value of this study. To achieve the goal a systematic literature review (SLR) has been carried out on 74 peer reviewed scientific articles and conference papers. The records have been subjected to a clustering process (qualitative analysis) and a subsequent univariable (frequencies and vertical percentages) and multivariable quantitative analysis (comparison of column proportions). The studies' theoretical approaches were identified and the levels of formalisation, the predominant objectives and the hypothesis were analysed. In addition, the analysis of the research areas of studies reveals the epistemological process and outcomes of the literature. Several conclusions are drawn such as the scientific literature in this field is limited in scope. Moreover, from an epistemological perspective, descriptive studies are predominant, mainly addressed from the field of engineering, as well as analytical studies, which are mainly undertaken from Social and Legal Sciences. There are two main groups of articles based on their purpose: those which seek to describe, detail or define; and those which are more innovative, which analyse, establish or deconstruct the phenomenon. The results also show that the level of methodological and theoretical formalisation is limited, which indicates that research is in an initial stage. The foregoing results lea

"Distinct rhetoric and approaches are used to communicate the facts and possibilities of the climate crisis and energy transitions. To better understand climate and energy-related communication practices and objectives at the national level, this research applies grounded theory analysis to transcripts of semi-structured interviews with intermediaries in Spain. The intermediaries interviewed include researchers, engineers, professionals with energy-related roles in government, and coordinators of electricity cooperatives. Our analysis produced two overarching results: (1) communication is seen as a means to raise awareness, change behavior, and engage the public, and each of these means is seen as a method to empower citizens; (2) the language of systemic change is used broadly to refer to changing political, economic, or technological systems; however, some systemic changes seem incomplete or incompatible with other systems. Further research is required to test these hypotheses and show how distinct communication approaches might be reconciled in energy transition policy and initiatives. "

"Videos featuring research results, laboratory tutorials, and online webinars are fundamental tools for disseminating science and boosting scientific impact. However, extended reality (XR) video technologies, which include virtual reality (VR), represent new challenges for scientists and science communicators. XR and VR can enhance, bend, or distort the reality surrounding scientific facts. The London Charter and Seville Principles are standards for computer-based visualization and reconstruction in a virtual reproduction of heritage sites and research in domains such as archaeology. Here, we develop a similar set of standards for the representation of scientific results in XR and VR and clarify the use of implicit XR and VR elements such as storytelling, setting, agency, interactivity, and other factors. Finally, the authors propose a framework XR/VR Model of Science Representation and Communication, derived from the context and other frameworks for representing information in virtual environments."
