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.

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.

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.

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.

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.
