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.

A wide gap exists between what scientists and rural farmers know. The rapid advancements in digital technology are likely to widen this gap even further. At the farmers' level, this knowledge gap often translates into poor and inefficient management of resources resulting in reduced profits and environmental pollution. Most modern rice cultivars can easily yield more than 5 tons per hectare when well managed, but millions of farmers often get less than 5 tons using the same production inputs.

Florence's La Specola Museum stirs up strong emotions. Among its collections, the valuable anatomical wax models created between the end of 17th and the beginning of 18th century stand out owing to their marvellous and provocative nature. The aim of this essay is to analyse the communication models epitomised by some of these works by means of historical semiotics, to nourish the widespread, but often underestimated assumption that science and the means used to spread it have always been influenced by intellectual suppositions and constantly interact with contemporary culture.

"Knowledge and information are essential for people to respond successfully to the opportunities and challenges of social, economic and technological changes (...). But to be useful, knowledge and information must be effectively communicated to people", says the Food and Agricultural Organization. India is home to a number of ICT-enabled development initiatives, and we will look at one of them to learn how an effective communication strategy is used.

As recognized by United Nations Secretary General Kofi Annan, the human community has reached a point in which it is faced with an array of choices that will determine the quality of our lives and the state of the global environment for present and future generations. One possibility is that at long last we will pave a path toward environmental stewardship and sustainable development. But it is also quite possible that we will travel a less enlightened course, running down the earth's natural capital and severely limiting the choices our descendants will face.

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.

All science undergraduates should do at least one philosophy course as part of their curriculum to augment their communication skills. This article sets out the arguments and the wider benefits for students of such courses.

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 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.
