In the summer of 2003, a survey was carried out at the At-Bristol Science Centre (UK) to determine the effectiveness of the hands-on activities of "Explore". The section evaluated included 43 interactive experiences divided into two themes. The first, "Get Connected", consisted of examples of the latest digital technologies, such as a television studio, virtual volleyball, and radars. The second, "Curiosity Zone", was dedicated to natural phenomena and subdivided into three additional groups: "Natural Forces" which presented various forces of nature, "Focus on Light", which dealt with the wonder of light, and "Sound Space", reserved for the science of sound. The survey was divided into two phases: the first consisted in observing the public's interaction with the hands-on activities; the second, in consulting the staff. The methods adopted helped determine the effectiveness of the exhibitdesign and the evaluation itself highlighted the role of a promoter of science as an evaluator.

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.

Free information works. In the sense that Open Access Journals, scientific journals which can be accessed at no cost, thereby guaranteeing free access to everyone, are at the same time able to guarantee the same quality as –or even better than- that of traditional journals, which can only be read by those willing to pay a price, be it the cover price or a subscription.

On September 15, 2001, a joint editorial simultaneously published in thirteen medical journals, pointed an accusing finger at the increasing pressures coming from the pharmaceutical industry. During past decades, a key role in trial design and conduct was played by independent clinical investigators working in academic medical centres. They were also able to vouchsafe the quality of their research, which might not, however, be the case in the future.

At the beginning of the new millennium, science is not only a neutral system or an objective methodology of knowledge, but also the implicit basis of the totality of our culture. Though science and its derivates are omnipresent in daily life, its basic ideologies and functional mechanisms are in most cases not fully visible to the subject. In using the most evolved systematical-critical model of psychoanalysis provided by the French thinker Jacques Lacan (1901-1981), an enlightening analysis of western science can be made, which contributes not only to a better understanding of its own psychology, but also of the hidden ties between science and its current socio-cultural background.

There is a substantial divergence between the standards of integrity associated with "good science" and the problems imposed by the conflict of interest on research, specially in the biomedical field. There are at least as many ways in which information may be altered and the production of new scientific knowledge may be affected as there are links that can be established between researchers, private companies, and editors and staff of the specialized press. The pressures resulting from this high number of connections can affect all stages of research, from trial design to data analysis, from result publishing and dissemination to who will be the author of the articles.
