The problem of accessing data is as old as science itself. Complete popularisation of scientific data (of a theoretical model), and even more so of the methods and materials used during an experimental process and of the empirical data amassed, has always been considered an essential part of the process of authentication, duplication and filing of scientific knowledge. It is also true, however, that this theory has always been a complex riddle with no simple solution. Strangely enough, in today's era of instant communication, the challenge of information access seems to be facing new, daunting obstacles, some of which have the same name and characteristics they had 100 or 300 years ago, but which have been intensified by new dimensions and unexpected corollaries. Others have a new core, an example being, the problem related to disclosure, which implies the (more or less) complete popularisation of the data, procedures, and tools used during research. This is a subject which, although ancient in form, has recently taken on new, far-reaching implications. The scientific community now has to face a problem which originated, first, with the sequencing of the human genome and, later, with that of certain types of rice; a problem which could redefine certain aspects of the epistemological practice and nature of science.

Halliday has demonstrated that changes in discourse function covary with changes in the grammatical resources a language makes available to construe discourse. Specifically, he outlined the ways in which nominalisation evolved as a resource for construing scientific reality as a world of logical relations among abstract entities. In the present article,

The use of photography in the field of psychiatry is an eloquent example of the complex evolution of the relationship between science, communication and society. The research that follows analyses the development of such a relationship in a crucial period of the history of psychiatry: the 1970s. That was the time that witnessed the revolution of a science which admitted the failure of its methods and "instruments", mental hospitals. That was also the time when a profound change took place in the communicative methods of photography related to this uncertain field of knowledge. A group of photographers, driven by the political situation of the time, covered the end of mental hospitals.

On 15 September 2001, thirteen major international journals, coordinated by the International Committee of Medical Journals Editors (ICMJE), published a joint editorial titled "Sponsorship, authorship, and accountability". Unfortunately, only four days from the tragedy of 9-11, there is no room in the media for other news. In the scientific world, however, the content of that editorial sets off an alarm: the conflict of interest undermines the objectivity of biomedical research and the credibility of international journals vouchsafeing the quality of that research.

Analysis of popular science magazines can offer a significant contribution to the study of the history of science popularisation and the relation between the language of science and everyday language in Italy. This paper reconstructs the history of science popularisation through analysis of popular science magazines published in Italy from 1788 to date. The material examined consists of 80 popular science magazines covering various scientific disciplines, reporting current issues and targeted at a non-specialist public. Such material had never been gathered and organised in a systematic way before. The analysis did not take into account academic scientific journals which generally cover a single discipline and use technical language or high-quality science popularisation journals which also use specialist language. The element that all 80 magazines have in common is the use of non-technical, easily understandable language for a public that does not possess any specialist scientific knowledge. The analysis of the material offers an overview of the scientific disciplines that have been covered more extensively in popular science magazines from the end of the 18th century to date. In addition, it shows how priorities in coverage changed in different historical periods and how a variety of science communication modes have been established over time.

On 16 January 2004, the United Nations Secretary-General and Nobel Peace Prize winner Kofi Annan launched a Global Media Aids Initiative, with the aim of convincing the press, radio, television and Internet to join the fight against what has been called the "forgotten disease of the forgotten continent". Throughout the world, over 40 million people have the Hiv virus. In 2003 there were 5 million new infections and 3 million deaths were caused by Aids.
