John Maynard Smith (1920–2004) was one of Britain's most eminent evolutionary biologists. For over forty years, from 1954 onwards, he also regularly appeared on radio and television. He primarily acted as a scientific expert on biology, but in the late 1960s and the 1970s he often spoke on the implications of science (biology and more generally) for society. Through four case studies, this paper analyses Maynard Smith's scientific broadcasting against developments within the BBC as well as the relation between science and society in Britain. It finds that while Maynard Smith acknowledged and accepted increasing mediation through the BBC and its producers, he stayed publicly and privately critical of both format and content decisions in his reflections on the science–media relationship. At the same time, we find that over a decade before the 1985 report by the Royal Society on the public understanding of science, Maynard Smith came to think of engagement with the public via the media as scientists’ responsibility.

This essay explores how hormone treatments were used to optimize and normalize individuals under Italian Fascism. It does so by taking the activities of the Biotypological Orthogenetic Institute − an Italian eugenics and endocrinological centre founded by Nicola Pende in 1926 − as the prime example of a version of eugenics, biotypology, which was based on hormone therapies. This essay first demonstrates that Italian Fascist biopolitics was not only concerned with increasing the size of the Italian population, but also with improving its quality. It suggests that under the Italian Fascist regime hormone therapies became eugenic tools of intervention to improve the Italian race. Second, while Pende's institute purportedly enhanced men and women, its activities show the extent to which the ‘techniques of normalization’ pursued by the Fascist regime were both systematic and invasive.

This article, through a case study of the Royal Dublin Society (RDS), traces the reception, experimentation with, and uses of radium in early twentieth-century Ireland. Throughout the nineteenth century there was increasing state intervention in the provision of scientific and technical education in Ireland. This culminated in the loss of the RDS's traditional role in this area. The article demonstrates that the RDS was forced to re-envisage its role as a scientific institution by actively seeking to support experimental research. Using radium as a case study, the article argues for the success of this tactic. It demonstrates that radium played a central role within the RDS as a nexus for the maintenance of an experimental and philanthropic culture that permeated much of the society's scientific output in this period. In doing this it highlights the importance of sociability in the promotion of science in Ireland in the early twentieth century. In addition, it explores the role of the RDS as an arbiter of scientific authority.

In the context of the telegraphic distribution of Greenwich time, while the early experiments, the roles of successive Astronomers Royal in its expansion, and its impacts on the standardization of time in Victorian Britain have all been evaluated, the attempts of George Biddell Airy and his collaborators in constructing the Royal Observatory's time signals as the authoritative source of standard time have been underexplored within the existing historical literature. This paper focuses on the wide-ranging activities of Airy, his assistant astronomers, telegraph engineers, clockmakers and others, which served to increase the reliability of the Royal Observatory's time service between the 1850s and 1870s. Airy and his collaborators aimed to mechanize and automate their telegraphic time distribution system in order to improve its accuracy and reliability. The accomplishment of such technological innovations was disseminated via public lectures, journal articles and correspondence with experts, secondary distributors of standard time and the general public. These communications were used to build public trust in the Greenwich time service. However, the unexplored archival material used in the present paper provides fresh insight into the unstable nature of the Greenwich time system, including its clear limits in terms of its scale of automation and degree of accuracy.
