Extinct species identification from late middle Pleistocene and earlier Upper Pleistocene bone fragments and tools not recognizable from their osteomorphological study by an enhanced proteomics protocol

Ancient preserved molecules offer the opportunity of gaining a deeper knowledge on their biological past. However, the development of a proteomic workflow remains a challenge. The analysis of fossils must involve a low quantity of material to avoid damaging the samples. In this study an enhanced proteomic protocol was applied to 5-milligram samples of about 130,000-year-old mammalian bones ranging from the end of the Middle Pleistocene up to the earlier Upper Pleistocene, excavated from Scladina Cave (Sclayn, Belgium). Using sequence homology with modern sequences, a biological classification was successfully achieved and the associated taxonomic ranks to each bone were identified consistently with the information gained from osteomorphological studies and palaeoenvironmental and palaeodietary data. Amino acid substitutions on collagens were identified, thus providing new information on extinct species sequences and helping in taxonomy-based clustering. Considering samples with no osteomorphological information, such as two fragments of bone retouchers, proteomics successfully identified the families providing paleontologists new information on these objects. Combining osteomorphology studies and amino acid variations identified by proteomics, one of the retouchers was potentially identified as belonging to the Ursus spelaeus species.     

‘It’s a horrible,horrible feeling’: ghosting and the layered geographies of absent–presence in the prison visiting room

This paper advances geographies of absence by considering the multiscalar, overlapping, ambiguous and reciprocal absences inherent in incarceration, and the compound nature of the experiential and embodied absences characteristic of prison visiting. It progresses extant literatures by considering as absent a group which differs from those previously thus conceptualised, and by postulating absence even when whereabouts are known and co-presence is possible. Drawing on a major RCUK-funded study of the socio-spatial context of prison visitation in the U.K., it brings carceral geographies and geographies of absence into productive dialogue, demonstrating that attention to the felt presence of absence in the context of prison visiting is highly revealing of the poignant and bittersweet nature of family contact during incarceration.     

Budgie smuggling or doing bird? Human-animal interactions in carceral space: prison(er) animals as abject and subject

Carceral geography, whilst in dialogue with many aspects of theory-building in contemporary human geography, including notions of affect, mobility and embodiment, has yet to meaningfully engage with animal geographies to consider the nonhuman dimension of carceral experience. Likewise, criminological scholarship of human-animal carceral co-presence has yet to progress far beyond the consideration of animals as mere ‘signifiers’ of human endeavour and meaning. Further, the study of prison animals has thus far considered only those nonhumans intentionally present in carceral space, such as therapeutic animals, eliding completely those considered ‘vermin’. This paper broadens the scope of extant scholarship, considering the parallels between the discourses of the ‘rehabilitation’ both of prisoners and prison animals during incarceration, and of both the prisoner and the prison animal as abject.
