Salted fish products from the Coptic monastery at Bawit, Egypt: evidence from the bones and texts

Fish bone assemblages are described that were recently discovered in the storage area of two rooms, dated to the 7th century AD, from the monastery of Bawit, Egypt. The species composition, the reconstructed sizes of the fish and the find contexts show that this material represents pickled fish (salsamenta). This product was made in one case of medium-sized Clarias catfish, whereas another assemblage, found inside an amphora, consisted of small-sized fish, mainly cyprinids and alestiids. The latter product was stored in a Late Roman Amphora 5/6 of Palestinian origin, traditionally considered as a container for wine. The amphora was clearly re-used since the fish found in it are Nilotic species which excludes that the salsamenta came from outside Egypt. A few additional finds of fish inside amphorae were available, but due to the low number of bones it was unclear if salted fish products were stored in them. Textual information provided by ostraca and papyri from the same site shows that the monks exerted fishing activities themselves and also suggests that the production of pickled fish took place locally. One of the two Nilotic fish taxa (Labeo) that is specifically mentioned by written evidence is the most common ingredient found in the amphora with abundant fish remains. The paper ends with a brief summary of other faunal evidence for salted fish products from monastic and other historic sites in Egypt.

The body language: The spontaneous influence of congruent bodily arousal on the awareness of emotional words

Nowadays, the idea of a reciprocal influence of physiological and psychological processes seems to be widely accepted. For instance, current theories of embodied emotion suggest that knowledge about an emotion concept involves simulations of bodily experienced emotional states relevant to the concept. In line with this framework, the present study investigated whether actual levels of physiological arousal interact with the processing of emotional words. Participants performed 2 blocks of an attentional blink task, once after a cycling session (increased arousal) and once after a relaxation session (reduced arousal). Concretely, participants were instructed to detect and report 2 target words (T1 and T2) presented among a series of nonword distractors. T1 and T2 were either neutral, high arousal, or low arousal words. Results revealed that increased physiological arousal led to improved reports of high arousal T2 words, whereas reduced physiological arousal led to improved reports of low arousal T2 words. Neutral T2 remained unaffected by the arousing conditions. These findings emphasize that actual levels of physiological arousal modulate the cognitive access to arousal (in-)congruent emotional concepts and suggest a direct grounding of emotion knowledge in our bodily systems of arousal.

Evidence of various mechanisms of Cd sequestration in the hyperaccumulator Arabidopsis halleri, the non accumulator Arabidopsis lyrata and their progenies by combined synchrotron-based techniques

Arabidopsis halleri is a model plant for Zn and Cd hyperaccumulation. The objective of this study was to determine the relationship between the chemical forms of Cd, its distribution in leaves, and Cd accumulation and tolerance. An interspecific cross was carried out between A. halleri and the non-tolerant and non-hyperaccumulating relative A. lyrata providing progenies segregating for Cd tolerance and accumulation. Cd speciation and distribution were investigated using X-ray absorption spectroscopy and microfocused X-ray fluorescence. In A. lyrata and non-tolerant progenies, Cd was coordinated by S atoms only or with a small contribution of O groups. Interestingly, the proportion of O ligands increased in A. halleri and tolerant progenies, and they were predominant in most of them, while S ligands were still present. Therefore, the binding of Cd with O ligands was associated with Cd tolerance. In A. halleri, Cd was mainly located in the xylem, phloem, and mesophyll tissue, suggesting a reallocation process for Cd within the plant. The distribution of the metal at the cell level was further discussed. In A. lyrata, the vascular bundles were also Cd enriched, but the epidermis was richer in Cd as compared with the mesophyll. Cd was identified in trichomes of both species. This work demonstrated that both Cd speciation and localization were related to the tolerance character of the plant.
