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.

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.

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.

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.

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.

Some recent events have brought to the attention of the general public the issue of free access to scientific information. On many occasions basic scientific information has been said to be constantly available to scientists. In truth, a group of scientists (those who live in the developing countries) have long remained on the fringes of the international research community and in part still are, mainly because of the existing difficulties in accessing scientific publications. However, this fact has never been as blatant as it was with the Human Genome Project. Indeed, the project saw an attempt to conceal and privatize the results of advanced basic research. On that occasion, the fear of a private exploitation of scientific results became a real threat.

In the midst of a debate on access to information, the World Health Organization and the FAO have decided to develop a strategy to guarantee the right of poor countries to have free access to scientific publications. This right is often denied, mainly because of high subscription costs. For this reason, universities and research centres in southern countries must forego buying magazines, which are a valuable instrument for updating, and exchanging information on research and scientific issues. This choice has been made in an historical period when the industrialized world is marked by a knowledge-based economy.
