The objective of this article is to present a panorama of the way in which journalistic coverage of science and technological themes is being carried out in Latin America, having as a case study seven newspapers of significant impact in the region. We analyzed all stories published by the science section during all the month of April 2004, in the following newspapers: La Nación, Argentina; El Mercurio, Chile; Mural, Mexico; El Comercio, Ecuador; O Globo, Folha de S. Paulo and Jornal do Commercio/Pernambuco, Brazil. A total of 482 texts were collected. The methodology joins quantitative and qualitative analysis. There are very few studies on science journalism in Latin America and even fewer that seek to explore a comparison among countries. We believe that studies such as ours can provide subsidies to stimulate the improvement of journalistic coverage of scientific and technological issues.

How does knowledge sharing affect scientists' everyday work in developing countries? And how important is it for the development not only of new scientific research, but also for improving the living conditions of local inhabitants? These are the questions that a group of scientists met to discuss during an international workshop on Knowledge Sharing for Local Development in the South held in Trieste, Italy (4-6 July 2005). Based on their personal experiences, their thoughts and opinions create an interesting insight into new practices for the public communication of science, medicine and technology from a point of view that is often under-estimated: the one of the scientists themselves. The workshop, organized by the Third World Network of Scientific Organizations (TWNSO) and the United Nations Development Programme's Special Unit for South-South Cooperation (UNDP-SSC), showcased 15 case studies that utilized a variety of knowledge sharing methods, and, in doing so, highlighted the critical role that knowledge sharing plays in sustainable development.

The historian Marshall Berman wrote that living in modern times means "to find ourselves in an environment that promises us adventure, power, joy, growth, transformation [...] and, at the same time, that threatens to destroy everything we have, everything we know".

Science and technology: these are the mainstays China wants to concentrate on in order to stabilise its future as an emerging world power. Beijing plans to have the whole, enormous Chinese population literate in the scientific field within a few years. Scientific popularization is the key to what now, due to political influences and deep social disparities, seems remote.

The image and perception of science and of scientists is a crucial topic, above all with regards to younger generations, the human capital of the future. For this reason, the National Research Council (CNR), in 2004, asked the IRPPS institute (Istituto di ricerche sulla popolazione e le politiche sociali) to carry out a sample survey of 800 people between the ages of 18 and 29 on the topic. Science and new technology emerged as the topics of most interest, in addition to medicine, history and economics. Scientific content in the mass media is considered to be satisfactory, whereas education in the field of science is considered to be less than satisfactory, above all in relation to the work environment. However, if research in Italy seems weak in the eyes of young people, scientists are not seen the same way but are considered society's second most important profession after that of the entrepreneur. The problem of trust in science is due, above all, to the politics of research, which do not encourage adequate investment in public and private sectors. A factor analysis technique was applied in order to identify models of attitude towards science of various subgroups within the population.

While knowledge-society is developing all around the world, science seems to be loosing its historical prestige in public perception, scientific vocations are declining among young people, "limit" on science is common subject of daily politics, research freedom is questioned in front of public good, scientists are dragged in front of public opinion. As a consequence, scientists are to be skilled in science communication. But communicating science is no more matter of "translating" scholar knowledge into lay language (popularization); it is mainly matter of crossing barriers of fundamental attitudes, understanding daily-life ends, sharing future scenarios and cultural values, becoming responsible for the societal dimension of science. Moreover, while confronting the coming Big Convergence (among nanosciences, bio-medical sciences, information and communication-sciences, neuro-cognitive sciences), science itself is called to cross barriers among disciplines, distinctions between pure and applied science, academic and industrial research, science and technology, etc. However, such crossovers are challenging for present education of scientists. The governance of the democratic knowledge-society not only demands more scientific education among citizens, but also a general revision of highest scientific curricula. What are the goals for educating scientists to public responsibility and participation? What are conceivable ways for joining the "two cultures" and integrating curricula? What cross-fertilizations are conceivable between natural and social sciences, scientific and humanistic education, specialised and more general formation?

The death of Pope John Paul II, the "Polish pope", in Rome and the subsequent election of Benedict XVI, the "German pope", have been two great events gaining world-wide media coverage and affecting the whole world. This was due to Karol Wojtyla's ability to reach everyone's heart ­ thus once dubbed the "Great Communicator" ­ and to the Vatican's spiritual, cultural, and political influence all over the world. The death of Pope John Paul II and the election of Benedict XVI also concern science and science communication issues.

The article proposes a reflection on science communication and on the communicative processes characteristic to the production of new-found knowledge. It aims to outline the role that sociology can play within this frame for greater understanding. The article first defines the main evolutionary trends in scientific research in recent decades, with particular reference to the emergence of new social actors. Following on from this, it will look at some of the epistemological conditions that may strengthen the sociologist's role in the cognition of scientific production. Using this as a premise, we will look at a typology for science communication and its components, as well as some of its governing principles. The conclusion of the article indicates the added value that can be gained from the use of such a model, with the particular aim of identifying indicators that allow the evaluation of scientific research in sociological terms as well as those already in existence.

Many lives could have been saved on 26 December 2004, when the tsunami unleashed by an earthquake of magnitude 9.0 off the coast of the Indonesian island Sumatra struck a dozen coastal villages along the Indian Ocean. Those lives could have been saved if, on that day, science communication had not resulted in a complete failure to communicate scientific information adequately in many cases, in different places and at different levels. A long time passed between the violent shock and the devastation caused by the tsunami waves ­ in most cases, many hours.
