In a brief article published by Science1 last October, British scientists stated that the expression "Public Understanding of Science" (PUS), which was traditionally employed in Anglosaxon societies to refer to the issue of the relationship between science, technology and society, is out-of-date. It should be replaced by "Public Engagement with Science and Technology" (PEST), a new acronym that clearly invites to reconceptualise the relationship between science and the public. The new approach involves the engagement of the public or rather the publics of science, through dialogue, in particular through an open and equal-to-equal discussion between scientists and non-experts that would enable non-experts to become the actual protagonists in the scientific decisions producing social effects.

In recent weeks, Britain's Better Regulation Task Force report on scientific research regulation asked the Government to evaluate the risks associated with the development of Nanosciences and Nanotechnologies. The Government was also asked to prove its implementation of a specific policy to protect human, animal and environmental safety, were it to be threatened by the development of this emerging field of knowledge. These requests may sound rather alarming.

Terms such as gmo, genetic tests and pharmacogenomics, which were once used only by experts, belong today to everyday language. The new vocabulary of molecular biology shows an increase in the interest of society in scientific problems, and in particular the recent cultural supremacy of molecular biology. For all of us, the gene symbolizes progress and power, the hope of fighting incurable diseases, and the fear of terrifying genetic manipulations. These aspects become real events and characters in the Human Genome Project. But this great international project has also shown that the relation between science and society is changing. This event can actually be seen as a metaphor of science leaving academic laboratories to settle new areas of society. From economics to sociology, from epistemological discourse to bioethical debate, from medicine to basic research, in all these fields genome becomes the main topic of discussion and food for thought. Public attention to this international project has grown constantly throughout its development, and it peaked when science came into contact with the press.

In the last few years, a continuous series of food alerts have caught the attention of the media and the public in Europe. First, eggs and pork contaminated with dioxins; then, "mad cow" disease, while, all along in the background, a battle against genetically modified plants has been in progress. These food alerts have had complex repercussions on the perception of risks associated with food production. Experts have often been divided over these issues, and the uncertainty of scientific data has been indicated on more than one occasion as one of the factors that influence risk perception. However, the most important factor seems to be undoubtedly the way in which the risk has been communicated (or not communicated) to the public. Therefore, risk communication analysis offers an excellent opportunity to understand the profound changes that are taking place in relations among the scientific community, mass media and other members of civil society now that they are fully aware that scientific and technological innovation, the real driving force of modern industrial society, is a source of development but also a source of risks which are not always acceptable. Within this different context, a debate open to all interested parties appears to have become a dire necessity for the "risk society", especially as far as food is concerned because food has extremely important psychological, ethical and cultural values.

Enrico Fermi's work gave birth to a real cultural revolution in the Italian scientific scenario. His scientific studies concerned almost every field in physics and had far-reaching effects of which virtually everybody, above all in Italy, is still taking advantage. Two important "by-products" of Fermi's ideas and initiatives will be here taken into consideration: the new way of carrying out research and communicating science invented by Fermi and his group and his publications for the general public, which often stood for high examples of scientific popularisation. Then the focus will shift on Ettore Majorana's role to try to understand why his work in the field of communication within the School of Physics of Rome was basically non-existent despite the excellent communicative skills he demonstrated both during his university lectures ­ also published in this magazine ­ and in his article "Il valore delle leggi statistiche nella fisica e nelle scienze sociali", the only one which does not deal with pure physics issues and which will be also taken into account in this paper.

This paper is concerned with the interactions between information technology and the humanities, and focuses on how the humanities have changed since adopting computers. The debate among humanists on the subject initially focuses on the alleged methodological changes brought about by the introduction of computing technology. It subsequently analyses the changes in research that were caused by IT not directly but indirectly, as a consequence of the changes effected on society as a whole. After briefly summarising the history of the interactions between information technology and the humanities, the paper draws on literature to examine the way humanists have perceived the evolution of their disciplines. The paper concludes by fitting the phenomenon into a model of scientific revolution.

This work analyses how the theme of the creation of thinking machines by man, particularly through artificial intelligence, is dealt with on stage, with reference to three plays addressing different topics and characterised by different types of performance. This analysis reveals the particular effectiveness of plays dealing with scientific topics, when the relationship between theatre and science results in reflections transcending the boundaries of its contents to address man and his essence and gives voice to the ancient question of the sense of the world.
