Molecular archaeology of Flaviviridae untranslated regions: duplicated RNA structures in the replication enhancer of flaviviruses and pestiviruses emerged via convergent evolution.

RNA secondary structures in the 3'untranslated regions (3'UTR) of the viruses of the family Flaviviridae, previously identified as essential (promoters) or beneficial (enhancers) for replication, have been analysed. Duplicated enhancer elements are revealed as a global feature in the evolution of the 3'UTR of distantly related viruses within the genera Flavivirus and Pestivirus. For the flaviviruses, duplicated structures occur in the 3'UTR of all four distantly related ecological virus subgroups (tick-borne, mosquito-borne, no known vector and insect-specific flaviviruses (ISFV). RNA structural differences distinguish tick-borne flaviviruses with discrete pathogenetic characteristics. For Aedes- and Culex-associated ISFV, secondary RNA structures with different conformations display numerous short ssRNA direct repeats, exposed as loops and bulges. Long quadruplicate regions comprise almost the entire 3'UTR of Culex-associated ISFV. Extended duplicated sequence and associated RNA structures were also discovered in the 3'UTR of pestiviruses. In both the Flavivirus and Pestivirus genera, duplicated RNA structures were localized to the enhancer regions of the 3'UTR suggesting an adaptive role predominantly in wild-type viruses. We propose sequence reiteration might act as a scaffold for dimerization of proteins involved in assembly of viral replicase complexes. Numerous nucleotide repeats exposed as loops/bulges might also interfere with host immune responses acting as a molecular sponge to sequester key host proteins or microRNAs.

Reflections: 50 Years of Medieval Archaeology, 1957-2007

This volume celebrates the 50th anniversary of the Society for Medieval Archaeology (established in 1957), presenting reflections on the history, development and future prospects of the discipline. The papers are drawn from a series of conferences and workshops that took place in 2007-2008, in addition to a number of contributions that were commissioned especially for the volume. They range from personal commentaries on the history of the Society and the growth of the subject, to historiographical, regional and thematic overviews of major trends in the evolution and current practice of medieval archaeology in Britain. Critical overviews are presented of the archaeology of medieval landscapes, buildings and material culture; new developments in the scientific study of medieval health, diet and materials; and innovations in social approaches to medieval archaeology. A series of papers on southern Europe provide a comparative perspective, featuring overviews on medieval archaeology in Italy, Spain and southeastern Europe.

Scales and voices in World Historical Archaeology

This paper briefly sets the scene for the articles that follow, introducing some key debates that have characterized the recent practice of historical archaeology. The definition of historical archaeology is explored according to parameters of chronology and methodology, drawing a distinction between New World traditions that define the subject as 'post-Columbian' and Old World approaches that establish broader connections with the 'documentary archaeology' of all literate societies. Current issues in European and American historical archaeology are highlighted, including the gradual breakdown of the medieval/post-medieval divide and the call for a global 'modern-world archaeology' to address the 'grand historical narratives' of the period, such as capitalism, economic improvement, and consumerism. The resistance to this global research agenda is explored with reference to archaeologies of diaspora and postcolonialism, which demand local perspectives to explore diversity and meaning. Finally, the innovative use of community archaeology and multi-vocality is introduced, with particular reference to the experimental narratives pursued by American historical archaeologists, in their new role as 'storytellers'.

The British Lower Palaeolithic of the early Middle Pleistocene

The archaeology of Britain during the early Middle Pleistocene (MIS 19–12) is represented by a number of key sites across eastern and southern England. These sites include Pakefield, Happisburgh 1, High Lodge, Warren Hill, Waverley Wood, Boxgrove, Kent's Cavern, and Westbury-sub-Mendip, alongside a ‘background scatter’ lithic record associated with the principal river systems (Bytham, pre-diversion Thames, and Solent) and raised beaches (Westbourne–Arundel). Hominin behaviour can be characterised in terms of: preferences for temperate or cool temperate climates and open/woodland mosaic habitats (indicated by mammalian fauna, mollusca, insects, and sediments); a biface-dominated material culture characterised by technological diversity, although with accompanying evidence for distinctive core and flake (Pakefield) and flake tool (High Lodge) assemblages; probable direct hunting-based subsistence strategies (with a focus upon large mammal fauna); and generally locally-focused spatial and landscape behaviours (principally indicated by raw material sources data), although with some evidence of dynamic, mobile and structured technological systems. The British data continues to support a ‘modified short chronology’ to the north of the Alps and the Pyrenees, with highly sporadic evidence for a hominin presence prior to 500–600 ka, although the ages of key assemblages are subject to ongoing debates regarding the chronology of the Bytham river terraces and the early Middle Pleistocene glaciations of East Anglia.
