Martin W. Bauer is right, two evolutionary processes are under way. These are quite significant and, in some way, they converge into public science communication: a deep evolution of discourse is unfolding, along with an even deeper change of the public understanding of science.

The world, all at once, has become a small world. Not only owing to TV, satellites and the Internet that allow us to jump from side to side of our planet in a click. But also owing to a phenomenon that evokes dry lands, devastating rains, tsunamis and hurricanes, torrid summers and melting glaciers: global warming. In the heated argument on this issue with so many people talking, in the past few years also artists have made their rising voice be heard. Artists-popularisers, aware of their role and of the considerable communication potential of the art medium. Because “One salient image, sculpture or event can speak louder than volumes of scientific data”.

Oficina Desafio, Challenge Workshop, is a project of UNICAMP Exploratory Science Museum – the Science Center of the State University of Campinas (Brazil). It is an outreach project, consisting of a fully - equipped mobile workshop constructed on a truck, which visits schools and gives the students open solution real problems challenging them to “design, construct and operate a device” capable of solving the challenge. Analysis of the evaluation forms answered by school students reveals that participants of the challenges perceive it as a “learning opportunity”, in the sense they identify school related capabilities as conditions that increase the chance of facing the challenges successfully.

In January 2006, my wife Susannah Sayler and I set out to photograph landscapes around the world that were being transformed by global warming. We called our work The Canary Project. From the beginning, as now, we had both activist aims and artistic ambitions. These two types of motivation overlap in places and in other places feel completely distinct. In general, we feel as though are carrying forward a torch that science cannot carry any further. Following are some thoughts on our role as activists and as artists and as collaborators with the scientific community.

Artists have used the environment as a subject forever and there is a long history of artists whose works affect peoples’ awareness of and perceptions of their natural environments. But only relatively recently have other artists become part of the modern environmental movement and of efforts to educate college students and the population at large about environmental issues. Environmental studies programs need to take advantage of this increased interest on the part of artists, and global warming provides a perfect vehicle.

“Web 2.0” is the mantra enthusiastically repeated in the past few years on anything concerning the production of culture, dialogue and online communication. Even science is changing, along with the processes involving the communication, collaboration and cooperation created through the web, yet rooted in some of its historical features of openness. For this issue, JCOM has asked some experts on the most recent changes in science to analyse the potential and the contradictions lying in online collaborative science. The new open science feeds on the opportunity to freely contribute to knowledge production, sharing not only data, but also software and hardware. But it is open also to the outside, where citizens use Web 2.0 instruments to discuss about science in a horizontal way.

The rapid spread of technologies involving the application of “Genetic Modification (GM)” raised the need for science communication on this new technology in society. To consider the communication on GM in the society, an understanding of the current mass media is required. This paper shows the whole picture of newspaper discourses on GM in Japan. For the Japanese public, newspapers represent one of the major sources of information on GM. We subjected the two Japanese newspapers with the largest circulation, the Asahi Shimbun and Yomiuri Shimbun, to an analysis of the full text of approximately 4000 articles on GM published over the past to perform an assessment of the change of reportage on GM. As for the most important results, our analysis shows that there are two significant shifts with respect to the major topics addressed in articles on GM by Japanese newspapers.

Those studying the public understanding of science and risk perception have held it clear for long: the relation between information and judgment elaboration is not a linear one at all. Among the reasons behind it, on the one hand, data never are totally “bare” and culturally neutral; on the other hand, in formulating a judgment having some value, the analytic component intertwines – sometimes unpredictably – with the cultural history and the personal elaboration of anyone of us.

Basing mainly on author's direct involvement in some science communication efforts in India, and other reports, this contribution depicts and analyses the present science communication/ popularization scenario in India. It tries to dispel a myth that rural people don't require or don’t crave for S&T information. It discusses need for science and technology communication, sustaining curiosity and creating role models. Citing cases of some natural, 'unnatural' and organized events, it recounts how S&T popularization efforts have fared during the past decade and a half. It's made possible using print, AV and interactive media which, at times, require lot of financial inputs. However, this contribution shows that a number of natural and other phenomena can be used to convince people about power of S&T and in molding their attitude. The cases cited may be from India, but, with a little variation, are true for most of the developing and under- developed societies.

Internet and the new media have been dramatically affecting the communication scenario. They are changing the role played by traditional media in the information processes, are creating new public spaces for dialogue and participation, and are triggering a short circuit among those producing and those receiving information. Even science communication is not stranger to the changes brought about by the new way of using and populating the web. An epitome of this process of change is the scientific podcast. This article will provide a brief review on the spreading and the purposes of podcasts in science communication, coming from a survey implemented as an activity of the course Science via podcast addressed to the second-year students of the Master in Science Communication of SISSA of Trieste.
