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 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.

Science was born when knowledge was no longer kept secret and became public. Its development is inextricably tied to the possibility that researchers continue to share the results of their discoveries as easily as possible. These are the points on which the concept of access to scientific information is based and on which the scientific community has founded its model of communication. However, there are currently numerous obstacles, mostly economic, preventing researchers from being real actors in the creation, control and verification process of scientific knowledge. Despite the technologies made available by the Internet, free access to scientific information continues to be limited by the cost of magazines and the opposition by the publishers. Hence, scientists have promoted an increasing number of initiatives with a view to re-confirming the principles of open access.

Scientific communication in court is particularly important for the understanding of the process of post-academic science communication. The purpose of this study, carried out through a qualitative approach, is: 1) verify whether and how the dynamics of an expert`s science communication in court can be traced back to the problem of public science communication. 2) underline specific characteristics of science communication in court. 3) propose a sample of a "general table on science communication", in order to be a ble to a nalyse every possible communication between the different parties of a legal proceeding.

The incident of Scanzano Jonico, in Italy's Basilicata region, has been something more than a lesson for those who handle the relationships between science and society. During November and December 2003 in this small southern Italian town a theory has been proven false. According to this theory, in the modern world, the best way to solve the problems put before society by science and technology would be for the experts to discuss them behind closed doors.

A ghost is wandering around the web: it is called open access, a proposal to modify the circulation system of scientific information which has landed on the sacred soil of scientific literature. The circulation system of scientific magazines has recently started faltering, not because this instrument is no longer a guarantee of quality, but rather for economic reasons. In countries such as Great Britain, as shown in the following chart, the past twenty years have seen a dramatic increase in subscription fees, exceeding by far the prices of other publishing products and the average inflation rate. The same trend applies to the United States.
