The scientific, ethical, and policy issues raised by research involving the engraftment of human neural stem cells into the brains of nonhuman primates are explored by an interdisciplinary working group in this Policy Forum. The authors consider the possibility that this research might alter the cognitive capacities of recipient great apes and monkeys, with potential significance for their moral status.

The prospect of using genome technologies to modify the human germline has raised profound moral disagreement but also emphasizes the need for wide-ranging discussion and a well-informed policy response. The Hinxton Group brought together scientists, ethicists, policymakers, and journal editors for an international, interdisciplinary meeting on this subject. This consensus statement formulated by the group calls for support of genome editing research and the development of a scientific roadmap for safety and efficacy; recognizes the ethical challenges involved in clinical reproductive (...) applications of genome editing but, importantly, rejects the idea that human reproductive germline modification is necessarily morally unacceptable; and highlights the importance of meaningful engagement in discussions of genome editing and the development of regulation and oversight mechanisms to govern future uses of such technologies.

This paper examines the stability of the concept of rumor in the past century. It is suggested that not only do models of explanation change, but rumors themselves also change - not only in content, but perhaps in the way they are believed or disbelieved. Social scientific interest in rumors begins with the birth of modern psychology in the 19th century, shifts to social psychology and sociology in mid-20th century, prompted by governmental concern over subversion through rumor during the Second (...) World War, and is finally revived by folklorists in more recent decades. A central assumption emerged that ambiguous situations create a vacuum which rumor fills. By the late 1960s, despite a decline in social scientific interest in the topic, a handful of significant empirical and theoretical challenges emerge from scattered studies. The discipline of folklore begins to take more interest in contemporary rumor in the 1970s, and by the early 1990s the rubric of the rumor is almost entirely supplanted in English language scholarship by the ‘urban legend’. It is argued that particular attention can and should be paid, in contemporary analysis, to the general information environment, the politics of belief, and cultural shifts in ideas about truth and falsity.
