In their contributions to this special issue, the British science writer Jon Turney and the American scholar Bruce Lewenstein discuss the validity of the book as a means for science communication in the era of the Internet, whereas the article by Vittorio Bo deals with scientific publishing in a broader sense.

What pushed His Excellency Enrico Fermi, acclaimed Academician of Italy entitled to a state car and driver, to leave Italy all of a sudden in December 1938 in order to reach New York, after a short stop in Stockholm for the ceremony that celebrated him as a Nobel laureate for physics, and to accept a job as a simple physics lecturer at the Columbia University?

A physicist. That is what John Ziman was in the beginning. As he tells us in “On being a physicist,” this implies a kind of nationality, that is, a laboriously learned identity that, at the end of the day, becomes natural. Physics was for him a way of seeing and a way of thinking, inextricably embedded in his own being: “a deeply rooted mode of personal existence.”

An effective communication of astronomy cannot take place without considering the view the general public has on the universe. Through a number of narrative interviews with non-experts, a research was carried out on personal cosmologies, to outline the public’s heterogeneous astronomical imagery. The result is a bundle of conceptions, perceptions and attitudes which are useful to interpret the difficulties the public experiences when facing the contents of astrophysics, and to establish an ongoing dialogue.

This article presents some of the challenges faced in developing an interactive exhibit on nanoscience and nanotechnology in Brazil. Presenting a scientific-technological area which is still in formation and which is little known by the population leads to a (re)consideration of the role of museums and science centers in the conformation and consolidation of scientific practice itself. Museographically, the exhibit deals with the challenge of making matter visible in an expression which is distant from the human perception. Some reflections are presented here on the option of musealization chosen which come from a broader evaluation of the exhibit.

John Ziman with his old-fashioned ways, was a real British gentleman of the colonies. Born and raised in New Zealand, Ziman belonged to that large group of men and women that went back to their fathers’ land in the last century from the Commonwealth countries. In many cases, they were individuals with an outstanding intellect and, therefore, a real tresure trove for Great Britain, which drew from those remote places not only gems, tea, perfumes and raw materials, but also enlightened minds and reliable personalities.

One can no longer rely on the presumption that scientists comply with the Mertonian value of disinterest and assume that they always tell the truth when spreading the results of their research projects. This can be rightly considered as the gist of the four-page report submitted to the board of the American journal Science by the committee chaired by the chemist John Brauman, from the Stanford University, and comprising three members from the Senior Editorial Board of the same journal, two eminent biologists specialised in stem cell research and a top editor from the other major general press medium of the Republic of Science, the British journal Nature.

When thinking about this contribution, an homage to John Ziman, one question occurred to me repeatedly: what would John have made of the European Research Council? Here is a newly established institution with the sole objective to fund ‘frontier research’ at EU level, based exclusively on scientific excellence and subject to pan-European competition of the best researchers. Would he have interpreted it as a vindication of academic science as a culture, a deliberate turning away from ‘post-academic science’ or even of overcoming it? Or, would he have seen it as the establishment of a small niche, to be recognized (and praised) for its respect for the norms of academic science, whose wider impact still has to be seen?

If Europe is to become a knowledge–based economy1 knowledge must be freely available in Europe. The results of research across Europe can not be left inside laboratories and libraries. It has to available to the citizens, young people and commerce of Europe. And the main source of information for all these groups is the mass media, yet large parts of European research do not allocate sufficient importance to media relations.

The attacks of September 11 2001 and in particular, the sending of letters containing anthrax spores the following October had a profound effect on society, and at the same time on science and its communicative mechanisms. Through a quanto-qualitative analysis of articles taken from four publications: two daily newspapers, the Corriere della Sera from Italy and the New York Times from the United States and two science magazines, Science and Nature, we have shown how the aforementioned events provoked the emergence of media attention regarding bioterrorism. A closer reading of the articles shows that today, science – including that found in science magazines – is closely related to politics, economics and the debate over the freedom to practice communicate. The very mechanisms of communication between scientists were changed as a result of this debate, as can be seen from the signing of the Denver Declaration in February 2003, which brought about the preventative self-censorship of publication of biomedical research findings.
