A short outline of the evolution of communications at CERN since 1993 and the parallel growth of the need both for professional communications and, at the same time, the need for training in more and more complex competencies for the new profession.

This commentary seeks to spark further discussion on the continuing professional development in science communication, presenting comments from practitioners who were asked to reflect on the competences and skills their profession requires, and to envisage what kind of training might provide them. This introduction presents some common issues that emerge within the comments: the necessity to face rapidly evolving professional landscapes, to answer to new missions and roles, to consider the growing impact and potential of new technologies. Alternative training methods are also discussed.

In respect of the different modes of science communication including journalism, radio, online, I would propose that the process of making exhibitions and centres dedicated to science & technology is one of the hardest creative typologies. It also provides a very different type of engagement to other modes, in that it works in real time and space with real tangible objects and responsive media. The power of the real is also extended through the direct and collective involvement of people, providing a refreshing antidote to the potential alienating nature of social media and the ever-growing obsession with the virtual. In this paper I will discuss the skills required by a designer in order to solve the challenges contained within the client brief (the project document provided by the client), and therefore the skills a proper exhibition designer training programme should deliver.

This commentary considers the topics of humour and online settings. Both have received increasing attention amongst researchers and practitioners of science communication, and both raise numerous questions around the role of informality and enjoyment in the spread of information. However, online settings also provide a great range of data with which to address these questions. Here I suggest that close consideration of technical infrastructure plays an important role in this data collection. I shall do so using case studies drawn from two popular participatory websites, reddit and Facebook, which display contrasting attitudes towards using humour. I argue that these attitudes are partly products of the different tools provided by the pages for users to show appreciation, which affect the appearance of content on the websites. I also suggest that these tools allow users to appreciate jokes in multiple ways, and by extension might provide researchers with methods for assessing different forms of engagement.

Science, research and emerging technologies often play a key role in many modern action movies. In this contribution we suggest to use genre analysis of folk narratives as an innovative and useful tool for understanding science and technology in action movies. In this contribution we outline our approach using illustrative examples and detail how understanding action movies as modern fairy tales can benefit the study of science, research and technology in popular culture.

Interest in the possible role for comedy as a medium for communicating and engaging the public in science is growing. However, current research has so far been restricted to exploring whether the content of scientific knowledge is accurate and precise within comedy, and whether the public might be said to understand science better for having watched it. In this commentary, I suggest that this approach neglects the diversity with which scientific ideas and images are used in comedy, particularly when comedy is written without the explicit goal of communicating science. I present my current research on the American animated comedy South Park, which suggests a different story: science serves to expose the hypocrisy and self-interest that governs the town. I suggest that examples such as South Park might benefit the analysis of comedy and science, by seeking to explain the very presence of science in comedy and in doing so, explore the values attributed to science within popular culture.

The prevalent lack of research on the interrelations between science, research and popular culture led to the organization of the first International Conference on Science and Research in Popular Culture #POPSCI2015, which took place at Alpen-Adria-Universität in Klagenfurt, Austria, from 17--18 September 2015. The aim of the conference was to bring together not only science communication researchers with an interest in popular culture, but also other scholars, scientists and researchers, artists, media professionals and members from the general public. In this issue of JCOM we present four invited commentaries which are all based on presentations at the conference.

While the use of scientific visualisations (such as brain scans) in popular science communication has been extensively studied, we argue for the importance of popular images (as demonstrated in various talks at #POPSCI2015), including pictures of everyday scenes of social life or references to pictures widely circulating in popular cultural contexts. We suggest that these images can be characterised in terms of a rhetorical theory of argumentation as working towards the production of evidentiality on the one hand, and as aiming to link science to familiar visualities on the other; our example is da Vinci's "Vitruvian Man".

For decades, particle physicists have been using open access archives of preprints, i.e. research papers shared before the submission to peer reviewed journals. With the shift to digital archives, this model has proved to be attractive to other disciplines: but can it be exported? In particle physics, archives do not only represent the medium of choice for the circulation of scientific knowledge, but they are central places to build a sense of belonging and to define one's role within the community.

Open Science may become the next scientific revolution, but still lingers in a pre-paradigmatic phase, characterised by the lack of established definitions and domains. Certainly, Open Science requires a new vision of the way to produce and share scientific knowledge, as well as new skills. Therefore, education plays a crucial role in supporting this cultural change along the path of science. This is the basic principle inspiring the collection of essays published in this issue of JCOM, which deals with many subjects ranging from open access to the public engagement in scientific research, from open data to the social function of preprint servers for the physicians' community. These are issues that go along with the targets of the FOSTER project (Facilitate Open Science Training for European Research) funded by the European Union, which has provided interesting food for thought in order to write this commentary.
