This article provides a starting position and scene-setter for an invited commentary series on science communication and public intellectualism. It begins by briefly considering what intellectualism and public intellectualism are, before discussing their relationship with science communication, especially in academia. It ends with a call to science communication academics and practitioners to either become more active in challenging the status quo, or to help support those who wish to by engendering a professional environment that encourages risk-taking and speaking-out in public about critical social issues.

Reflecting on the public role of academics, this issue of JCOM includes a set of commentaries exploring public intellectuals and intellectualism. The commentaries explore the role of academics in public debates, both as bringers of facts and passion. These pieces, together with past commentaries and letters to JCOM raise interesting questions about the role of academics in public debates that are, perhaps not those usually trodden in the academic literature.

While science communication has become increasingly professionalised, philosophers have been far less active in, and reflective about, how we talk to the public. In thinking about the relationship between the ‘public intellectual’ and science communication, however,  philosophy has some important contributions to make, despite the differences of content and disciplinary approach. What, then, can both these professions learn from each other about how to engage with the public - and the risks that this might involve?

Arthur Dent's reluctant hitchhike through the Milky Way would not have been possible without the babelfish, which was nourished by his brain waves and in return decoded foreign languages for him. In much the same way, public intellectuals serve as science and technology academia's babelfish for the non-STEM savvy. While STEM academics continue to push back the frontiers of knowledge, public intellectuals equip the community with the knowledge we need to make big decisions, both for our own individual lives and for our society.

In an information free-for-all why should scientists bother to add their voice? In this commentary piece I argue there is an increasingly important role for scientists amongst the growing ranks of public intellectuals and the many who style themselves as such. First, we must become the sifters and sorters. We need to be willing to use our research and analytical skills to identify what is valuable amongst all the noise, and, if necessary, to volubly reject what is not. And, second, we need to create and defend the space everyone needs for deep thought and consideration. We need to influence ongoing debates by seeking to push them towards evidence-based arguments and areas of scientific consensus. To sift out the deliberately distracting stories and to counter fake news.

This commentary is both a case study of the evolution of one public intellectual, and an analysis of how he has broadened his voice beyond the standard academic bubble. His story gives a perspective on the question of, “How do public intellectuals get their start?” They almost certainly begin as “mere” intellectuals — the public part comes later. But how? How does a studious academic go from following the media to being part of the media?

van den Sanden and Vries curate reflections and insights about the shared goals, practices and processes which bring together academics and practitioners in science education and communication. The book spotlights areas of productive overlap but is just the beginning for meaningful collaboration.

This paper briefly describes a new academic discussion project first presented on November 29th, 2016, at the "Universum Sciences Museum" in Mexico City. Interdisciplinary professionals comprise the Museological Reflections Group (MRG), whose aim is to think and explore new possibilities for science museums. The group's first edition, offered the theme "The Sciences behind Showcases: Anthropological and Archaeological Processes".

Englehard et al. provide a wide-ranging look at synthetic biology, from discussion of how one might classify different synthetic approaches to consideration of risk and ethical issues. The chapter on public engagement considers why synthetic biology seems to sit below the public radar.

This letter reflects on how the role of science in society evolved in 2016. While there were plenty of groundbreaking scientific discoveries, the shifting political landscape cultivated a tempestuous relationship between science and society. We discuss these developments and the potential role of the science communication community in political activism.
