We have published this issue of JCOM while the call for papers is open for the twelfth Public Communication of Science and Technology conference. The biennial meeting will be held in April 2012 and for the first time in Italy: the hosting city in Florence. The 2012 edition of the PCST conference is being held after more than twenty years of growth of the network of scholars that founded it and the expansion of its boundaries outside the European context from which it was created. JCOM is a part of this network, made up not only of individuals but also of organisations, university departments, journals, national conferences and so on.

What role and citizenship has the scientific thought on the web, or rather on the social side of the web? Does it benefit from the debate between peers and with the general public, or else does it only risk to become a monologue? How to deal with the number of instruments the Internet is able to provide in making, discussing and disseminating research? These are some of the questions tackled by the reflections from scholars and experts which were the basis for our debate.

The Internet has become a worldwide phenomenon. It is undeniable that the Net has forcefully entered everyday life, ceasing to be a useful tool only for a small circle of researchers and academics, to become a new and versatile means of mass communication. And measuring Internet access and calculating the number of Internet users is not easy. By using the domain names registered in the “.it” as an endogenous metric, the Institute of Informatics and Telematics of the Italian National Research Council (IIT-CNR) carried out a research on Internet diffusion in Italy taking into account some major categories of users (enterprises, non-profit organizations, individuals, professionals and public bodies) and territorial distribution (nation, macro-area, region and province). This research has made it possible to carry out an initial analysis of the digital divide in Italy.

A significant number of mass media news stories on climate change quote scientific publications. However, the journalistic process of popularizing scientific research regarding climate change has been profoundly criticized for being manipulative and inaccurate. This preliminary study used content analysis to examine the accuracy of Danish high quality newspapers in quoting scientific publications from 1997 to 2009. Out of 88 articles, 46 contained inaccuracies though the majority was found to be insignificant and random. The study concludes that Danish broadsheet newspapers are ‘moderately inaccurate’ in quoting science publications but are not deliberately hyping scientific claims. However, the study also shows that 11% contained confusion of source, meaning that statements originating from press material or other news outlets were incorrectly credited to scientific peer-reviewed publications.

Regenerative medicine (RM) has the potential to strongly impact on society. To determine non-experts’ impressions of RM, we analyzed opinions obtained from workshops in which participants freely discussed RM. Three major features were apparent. First, non-experts were most concerned with the possible effects of RM after it has been fully realized in society. Second, non-experts expressed concerns not only about RM itself, but also about the governance and operation of the technology. Third, non-experts were not only concerned about direct influences of RM, but also about its potential indirect influences. These identified features are likely to be controversial issues when RM is introduced into society. It is important to promote early discussion of these issues by society as a whole.

In colonial times in New Zealand the portrayal of science to the public had a sense of theatre, with nineteenth and early twentieth century grand exhibitions of a new nation’s resources and its technological achievements complemented by spectacular public lectures and demonstrations by visitors from overseas and scientific ‘showmen’. However, from 1926 to the mid-1990s there were few public displays of scientific research and its applications, corresponding to an inward-looking science regime presided over by the Government science agency, the Department of Scientific and Industrial Research. The subsequent development of science centres with their emphasis on visitor participation has led to an increase in the audience for science and a revival of theatricality in presentation of exhibitions, demonstration lectures, café scientifiques, and science-related activities.

The interview concerns the role of scientific books in the Italian society from the 19th century until today. Having played an important role in the formation of a national scientific community, science popularization has offered a ceaseless high-quality production during the past two centuries. On the other hand, even today scientific publications do reach only a narrow élite. In the author’s opinion, only the school system has the power to widen the public for science in Italy.

The interview presents an overview on the role of scientific publications during some key periods in United States history. It describes the developing of a culture scientifique in the late XIX century and the increasing relevance of the US within the scientific world, intertwined with a new public demand for science stories; only during the Cold War some books begin to question science. The author here argues that scientific books are a key marker of the way science fits the American culture.

Catechism, a literary genre of a religious origin, was once employed in the teaching of ‘lay’ subjects, especially of a technical nature. This is a review of this past editorial tradition which illustrates the potentialities and the limitations of agrarian catechisms, with a special focus on their spreading across Southern Italy in the late Enlightenment. This paper reflects on whether a book was the best instrument to hand down procedures and notions to people who supposedly were illiterate or unschooled.

The interview portrays the role of scientific books during the Renaissance. Books written within the tradition of skilled technical and intellectual practice shaped the way that led to the birth of modern science. Rooted in a panorama characterized by the multiplicity of cultural authorities, scientific books deeply influenced Renaissance culture and created networks interlaced with the existing trade channels. Big single-authored works, typical in the Renaissance, thereafter would be replaced by smaller-scale publications.
