The digitalization process of historical archives, which has been taking place over the past few years, shows that the study of history of science is undergoing major changes. Easier access to online resources (manuscripts, catalogues of scientific machinery and tools that would otherwise be virtually impossible to consult) has spurred and created the preconditions for the development of new quantitative methodologies in the study of history of science as well as the creation of international research groups.

Since the first pioneering balloon flight undertaken in France in 1783, aerial ascents became an ordinary show for the citizens of the great European cities until the end of the XIX century. Scientists welcomed balloons as an extraordinary device to explore the aerial ocean and find answers to their questions. At the same time, due to the theatricality of ballooning, sky became a unique stage where science could make an exhibition of itself. Namely, ballooning was not only a scientific device, but a way to communicate science as well. Starting from studies concerning the public facet of aerial ascents and from the reports of the aeronauts themselves, this essay explores the importance of balloon flights in growing the public sphere of science. Also, the reasons that led scientists to exploit “the show of science aloft” (earning funds, public support, dissemination of scientific culture…) will be presented and discussed.

In the Rafael Nieto Auditorium of the National Autonomous University of San Luis Potosi Mexico, few chairs are empty. The room is full of Astrophysics professors, Solid State of Matter, Elementary Particles, Fluid Mechanics, etc. It is the 49th National Congress of Physic. Today ­extraordinarily- it has slip into the program an analysis round table about the new outlines in science museums in Mexico.

The Scientific Communications Act of 2007 (HR 1453) was introduced by the US House of Representatives on 9th March. The National Science Foundation, an independent United States Government agency that supports fundamental research and education, has thus been allowed to spend ten million dollars for each of the fiscal years 2008 through 2012 to provide communications training to improve the ability of scientists to engage in public dialogue.

ECSITE is the European network of science centres and museums (www.ecsite.net). The ECSITE Annual Conference, attended every year by several hundreds of professionals in science museums and science centres (870 at the last edition), and the ECSITE director forum, where full members of the association discuss on focused topics, are excellent observation points. Looking at what goes on in these meetings allows to track what is high on the agenda of the science-centre community, how the focus of interest moves, what are the main concerns of museum professionals.

What is the role of science museums nowadays? If we want to answer this question, we need to understand the historical period we are living and what role(s) museums can play. We are undoubtedly at the beginning of a new age based on a new relation between science and society, a concept which has been explained and repeated by sociologists and economists over and over again and is confirmed by statistics.

Being aware of the fact that science is a decisive factor for development and individual well being and a citizen's right, no less important than all his other rights, Tunisia's new-Era initiated its Science City on 10 April, 1992. The purpose of such an institution is to disseminate science throughout the whole of Tunisia for the different categories of citizens and to help, in the context of dovetailing with the educational sector, youngsters get, from their earliest years, interested in science and its use.

In a meta-analysis carried out in 2002, the two main associations of science centres and museums (ASTC, mainly US-centered, and ECSITE, mainly European) gathered all studies analysing the impact of science centres and museums on their local communities1. Four types of impact were identified: personal, social, political and economical. It was noticed that the vast majority of studies concentrated on the personal impact (that is, learning outcome, visitor satisfaction, etc.), while the latter three were largely neglected. The very fact of pointing this out, and many recent experiences - some of which are included in this commentary - show that there is now a shift of attention.

Scientific publishing, here to be considered in a broader sense, as publishing of both specialised scientific journals and science popularisation works addressed to a wider audience, has been sailing for some years on troubled waters. To gather some possible food for thought is the purpose of this brief article.

We inhabit an age in which economic progress in the European Union is equalized to more European research and better communication of that European research to the public. In highly developed Western democracies this implies an important role for the public as well as the mass media, both actors in a transforming public sphere. Beyond a call for more communication and more scientific literacy, the discourse has shifted to a call for more engagement and more participation on behalf of the citizen. There is a widespread sentiment however that the discipline of science communication is at a crossroads. In this paper it is argued that in a context of life politics and an increasing displacement of politics, one has to account for the trajectories of issue formation and the detours of public-ization to understand the dynamics of techno-scientific issues.
