Gesture politics and the art of ambiguity: the Iron Age statue from Hirschlanden

NoThe discovery of the extraordinary Hirschlanden figure was reported in this journal in 1964. Since then the statue has featured in numerous discussions of Iron Age art and society, to the extent that it has become one of the iconic images of the European Iron Age. It has become almost taken for granted that the Hirschlanden figure is an `intensely masculine¿ warrior statue representing the heroised dead. However, certain aspects of the figure suggest a rather deeper, more ambiguous symbolism. The authors use their up-to-date critique to raise questions about the eclectic character of Iron Age spirituality

Death and Display in the North Atlantic: The Bronze and Iron Age Human Remains from Cnip, Lewis, Outer Hebrides

YesThis paper revisits the series of disarticulated human remains discovered during the 1980s excavations of the Cnip wheelhouse complex in Lewis. Four fragments of human bone, including two worked cranial fragments, were originally dated to the 1st centuries BC/AD based on stratigraphic association. Osteoarchaeological reanalysis and AMS dating now provide a broader cultural context for these remains and indicate that at least one adult cranium was brought to the site more than a thousand years after the death of the individual to whom it had belonged

Allosteric modulation of beta1 integrin function induces lung repair in animal model of emphysema.

Emphysema is a progressive lung disease characterised by loss of lung parenchyma with associated functional changes including decreased tissue elastance. Here we report beta1 integrin is a novel target for tissue repair and regeneration in emphysema. We show a single dose of a monoclonal antibody against beta1 integrin induced both functional and structural reversal of elastase-induced lung injury in vivo, and we found that similar matrix remodelling changes occurred in human lung tissue. We also identified a potential mechanism of action as this allosteric modulation of beta1 integrin inhibited elastase-induced caspase activation, F-actin aggregate formation and changes in cellular ATP levels. This was accompanied by maintenance of beta1?integrin levels and inhibition of caveolin-1 phosphorylation. We propose that allosteric modulation of beta1 integrin-mediated mechanosensing prevents cell death associated with lung injury and progressive emphysema, thus allowing cells to survive and for repair and regeneration to ensue

Le Castellan (Istres, Bouches-du-Rhône) : resultats de prospections géophysique

YesTwo seasons of geophysical prospection (magnetic, resistance and ground-penetrating radar) were conducted at the Iron Age oppidum of Le Castellan, Istres, Bouches-du-Rhône, in order to determine the utility of these techniques for sites in this region. The survey revealed numerous strong anomalies, of which many ran parallel or perpendicular to one another. These are the sorts of responses one might expect from the remains of buried stone wall foundations; this interpretation is supported by the presence, on the west side of the site, of exposed walls on the same alignment as certain of the geophysical anomalies. Overall, the evidence suggests a network of buried buildings and road-ways across the oppidum. One particularly substantial building was identified towards the centre of the site, through the presence of a strong resistance anomaly of distinctly rectilinear form. It appears to represent the remains of a buried stone building with three rooms. In conclusion, the results provide strong encouragement for the further application of geophysical survey in this regio

Atlas Toolkit: Fast registration of 3D morphological datasets in the absence of landmarks

Image registration is a gateway technology for Developmental Systems Biology, enabling computational analysis of related datasets within a shared coordinate system. Many registration tools rely on landmarks to ensure that datasets are correctly aligned; yet suitable landmarks are not present in many datasets. Atlas Toolkit is a Fiji/ImageJ plugin collection offering elastic group-wise registration of 3D morphological datasets, guided by segmentation of the interesting morphology. We demonstrate the method by combinatorial mapping of cell signalling events in the developing eyes of chick embryos, and use the integrated datasets to predictively enumerate Gene Regulatory Network states

Archaeological signatures of landscape and settlement change on the Isle of Harris

Between 2004 and 2011, a programme of archaeological investigation by the University of Birmingham on the Isle of Harris, a distinctive island forming part of the Western Isles of Scotland, has allowed the archaeological remains of this enigmatic place to be further characterised and understood. Despite intensive archaeological interest in the archipelago for a number of decades, the Isle of Harris has been overlooked and only now are we beginning to identify the archaeological resource and make comparisons to the wealth of published data from islands such as the Uists, Barra and Lewis. This paper highlights some generic overall patterns of archaeological signatures on the Isle which has been identified through a range of archaeological methods including field walking, intrusive excavation, aerial reconnaissance, geophysical and topographical survey, and documentary research. Several key case studies will be introduced including upland shieling complexes and mulitperiod settlement sites on the west coast machair systems. The purpose of the paper is not to present a gazetteer of the results of the work to date, but to highlight some of the key findings with a view to demonstrating that the Isle of Harris is directly comparable with the archaeologically rich landscapes of the other islands
