Racial and ethnic categories have appeared in recent scientific work in novel ways and in relation to a variety of disciplines: medicine, forensics, population genetics and also developments in popular genealogy. Once again, biology is foregrounded in the discussion of human identity. Of particular importance is the preoccupation with origins and personal discovery and the increasing use of racial and ethnic categories in social policy. This new genetic knowledge, expressed in technology and practice, has the potential to disrupt how race and ethnicity are debated, managed and lived. As such, this volume investigates the ways in which existing social categories are both maintained and transformed at the intersection of the natural (sciences) and the cultural (politics). The contributors include medical researchers, anthropologists, historians of science and sociologists of race relations; together, they explore the new and challenging landscape where biology becomes the stuff of identity.

Psychologists have done a great deal of research on the effects of trauma on the individual, revealing the paradox that violent experiences are often secreted away beyond easy accessibility, becoming impossible to verbalize explicitly. However, comparatively little research has been done on the transgenerational effects of trauma and the means by which experiences are transmitted from person to person across time to become intrinsic parts of the social fabric. With eight contributions covering Africa, Central and South America, China, Europe, and the Middle East, this volume sheds new light on the role of memory in constructing popular histories - or historiographies - of violence in the absence of, or in contradistinction to, authoritative written histories. It brings new ethnographic data to light and presents a truly cross-cultural range of case studies that will greatly enhance the discussion of memory and violence across disciplines.

African Americans and others in the African diaspora have increasingly "come home" to Africa to visit the sites at which their ancestors were enslaved and shipped. In this nuanced analysis of homecoming, Katharina Schramm analyzes how a shared rhetoric of the (Pan-)African family is produced among African hosts and Diasporan returnees and at the same time contested in practice. She examines the varying interpretations and appropriations of significant sites (e.g. the slave forts), events (e.g. Emancipation Day) and discourses (e.g. repatriation) in Ghana to highlight these dynamics. From this, she develops her notions of diaspora, home, homecoming, memory and identity that reflect the complexity and multiple reverberations of these cultural encounters beyond the sphere of roots tourism.
