In 1995, journalist Dava Sobel's Longitude caused an earthquake in the history of science community. The present article analyses how only recently historians of science have fully realized the novelty the book represented. In the meantime, the international success of popular books by journalists on the history of science has become a well-known phenomenon. The author suggests that the huge publishing success of Sobel's book ­ the "Sobel Effect" ­ has provoked three main kinds of reaction among historians: rejection, detachment, and imitation. Which of the three strategies is the best, for both public and authors?

Most universities in the United States have little or no idea about how the public perceives the importance of research done at these institutions. Learning whether the public believes academic research is valuable, meaningful, and practical has implications for higher education, if the public believes that university research is of little worth. This project utilized naturalistic and qualitative methods to learn how alumni perceived the importance of research at a major public university with a heavy concentration in research (Texas A&M University). Long interviews using open-ended questions were conducted with 133 alumni at 33 locations in Texas. Interviews were transcribed, unitized, and coded using qualitative methods, and themes were identified. Findings provide insights into whether the public believes university research is important, how the public learns about research, whether public relations programs are effective, the importance of research and teaching, and the types of research the public wants universities to pursue. A framework is proposed to learn about how well the public understands science and to measure the effectiveness of media and education programs to raise both science awareness and understanding of science.

Historical background The BBC Radio Science Unit has its roots in two radio networks, going back more than 40 years. In the late 1950s, BBC External Services (now World Service), appointed a science correspondent and began a weekly science magazine programme. Initially called `Science and Industry', it changed its name in about 1964 to `Science in Action'. It is still running today, after more than 2000 editions, probably making it the longest running science show on radio.

The Radio is an instrument of communication that has percolated to all the strata of the diverse Indian society. Its position has been consolidated through history as a regular companion and a source of information and entertainment. Its affordability, accessibility and non-reliance on costly resources have ensured its presence in almost all the households. It has become indispensable from kitchens, family rooms and even workspaces. It is one of the few or rather the only medium of communication after the print media wherein information dissemination still is primary and entertainment a secondary requirement, especially the rural areas.

The question was raised in the 4th November copy of The New York Times when it entitled the editorial of Garry Wills (political and cultural historian), regarding the re-election of George W. Bush, "The Day the Enlightenment Went Out". Wills' theory, with which the directors of the newspaper palpably concur, is that Bush was re-elected because "many more Americans believe in the Virgin Birth than in Darwin's theory of evolution".

The international symposium "Science on air: the role of radio in science communication" was held in Trieste on 1 and 2 October, 2004. To our knowledge, it is the first conference ever specifically held on science on radio, and it is certainly the first time science radio journalists, researchers, and media experts from 16 different countries met to discuss their journalistic practice and the role of radio in science communication. The main results are presented in this article.

The scientific institution in Brazil is marching to a good rhythm. Despite problems in funding (and in the very irregular distribution of such funds), universities and private research centers changed and grew over the last few years. In 1999, Brazil (whose external debt is over 50% of GDP), invested 0.87% of GDP in Research & Development: a percentage comparable to that of several Mediterranean countries.

Internal scientific communication and public communication of science and technology are growing in Brazil at a good pace, along with scientific productivity. In this Focus we will try to analyze the debate on standard or alternative models of communication of science that can be seen in the practice of science journalism and popular science in Brazil.

What makes a science story? Behind the scene there are many choices: what, how and when to broadcast. Decisions are made according to the general criteria of news values to which we add two groups: personal and emerging criteria. General criteria of choices are news values for the science stories. According to Tonner, stories containing human interest are important in everyday life, report less complicate discoveries and science as a part of the broader subject comes to the media easily.
