Bacteriophages are viruses that utilise bacterial cells as factories for their own propagation and as safe havens for their genomic material. They are capable of equipping bacteria with properties that bestow environmental advantages. They are also capable of specifically and efficiently killing bacteria.Bacteriophages are resilient in a wide diversity of environments, presumed to be as ancient as life itself, and are estimated to be the most numerous biological entities on the planet. Their overarching capacity to survive via molecular adaptation is supported by an arsenal of encoded enzymatic tools, which also enabled biotechnology. This volume includes contributions that describe bacteriophages as nanomachines, genetic engineers, and also as medicines and technologies of the future, including relevant production and process issues.

Crick and Watson's discovery of the structure of DNA fifty years ago marked one of the great turning points in the history of science. Biology, immunology, medicine and genetics have all been radically transformed in the succeeding half-century, and the double helix has become an icon of our times. This fascinating exploration of a scientific phenomenon provides a lucid and engaging account of the background and context for the discovery, its significance and afterlife, while a series of essays by leading scientists, historians and commentators offers uniquely individual perspectives on DNA and its impact on modern science and society.

Conservative Reductionism sets out a new theory of the relationship between physics and the special sciences within the framework of functionalism. It argues that it is wrong-headed to conceive an opposition between functional and physical properties (or functional and physical descriptions, respectively) and to build an anti-reductionist argument on multiple realization. By contrast, (a) all properties that there are in the world, including the physical ones, are functional properties in the sense of being causal properties, and (b) all true descriptions (laws, theories) that the.
In 1949, Ireland left the Commonwealth and the British Empire began its long fragmentation. The relationship between the new Republic of Ireland and Britain was a complex one however, and the traditional assumption that the Republic would universally support self-determination overseas and object to 'imperialism' does not hold up to historical scrutiny. In reality, for economic and geopolitical reasons, the Republic of Ireland played an important role in supporting the Empire- demonstrated clearly in Ireland's active involvement in the Cyprus Emergency of the 1950s. As Helen O'Shea reveals, while the IRA formed immediate links with EOKA and the Cypriot rebels, the Irish government and the Irish Church supported the British line- which was to retain Cyprus as the Middle-Eastern base of the British Empire following the loss of Egypt. Ireland and the End of the British Empire challenges the received historiography of the period and constitutes a valuable addition to our understanding of Ireland and the British Empire.
