The world is facing an unprecedented situation in health management as fast transport and travel lead to spread of diseases at a rate that has not been seen before and into countries that had once conquered them. This is even more evident with infectious diseases which do not respect geopolitical barriers or economic progress. It is becoming increasingly clear that control of such diseases and good practices for public health need global sharing of knowledge and international cooperation. In addition networking of institutions involved in health care with the communities that they serve is fundamental to containing diseases and promoting good health. For reasons as yet unclear even non infectious diseases such as obesity, hypertension and diabetes are also increasing at an alarming rate globally. The advantages of international networking and timely communication which contained three diseases will be discussed in this article.

If we wish to attempt an initial analysis of the inquiry on the communication of science in Brazil, India and China that JCOM proposed in its three most recent issues, we should paraphrase Chinese science and science-fiction writer, Yan Wu: even though these three countries are emerging in the fields of economy and science, and are now part of a wide group of communicators, promoting numerous methods to divulge information, they don't yet have a sound theory on the communication of science to the public. This is not an insignificant problem because according to David Dickson, the director of SciDev.Net, democratic dialogue on scientific matters is crucial to modern societies. However, it is difficult to propose the highest possible level of democratic dialogue on science topics without having a sound theory about the communication of science. In addition, the difficulties increase in those countries where developing economies and systems of science are both new and impetuous, as is the case of Brazil, India and China.

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.

"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.

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".

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.

I have been involved in College education since my days as a student in the Universidad de Buenos Aires. At that time, 1960, I helped to teach the course of Scientific Russian given in the Faculty of Sciences; strange as it might seem, the aim of the course was to allow the students to use scientific books especially in the area of Physics and Mathematics.

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.
