We present the case of a 52-year-old female born in the Sahara, who came to emergency services because of a cervical mass that had been growing progressively for the past 7 months (Fig. 1A). The patient presented moderate-effort dyspnea and dysphagia, without fever. Relevant personal antecedents included intervention for multinodular goiter a year earlier in Mauritania. Physical examination rev...

We investigated the crystal and structural behavior of several Cr-bearing spinels from the Archean chromitites of Amsaga (Mauritania). The chemical and structural data testified a retrograde metamorphism from amphibolite to greenschist facies, witnessed by relative changes in the amount of all the major oxides (Cr, Al, Mg, Fe2+, Fe3+), the relative proportion of Fe/Fetot as well as the structur...

The challenge of understanding refugee movements is huge and affects countries worldwide on a daily basis. Yet, in terms of simulation, the challenge appears to have been largely ignored. I argue that we as researchers can, and should, harness our computational skills to better understand and predict refugee movements. I reflect on the computational challenges of modelling refugees, and present...

In this paper, two new species of the genus Rosalinda found growing on bivalves from West African cold-water coral mounds are described. nowaldi sp. nov. was Acesta angolensis (Adam & Knudsen, 1955) off northern Angola, and lundalvi excavata (Fabricius, 1779) Mauritania. Both have a similar cnidome, but they can be easily differentiated by structure their hydrorhizae number tentacles hydranths....

Rift Valley fever virus (RVFv) is capable of causing dramatic outbreaks amongst economically important animal species and is capable of causing severe symptoms and mortality in humans. RVFv is known to circulate widely throughout East Africa; serologic evidence of exposure has also been found in some northern African countries, including Mauritania. This study aimed to ascertain whether RVFv is...

[1] By combining reconstruction of airmass backtrajectories from dust deposition sites in Europe and measurements of the (Nd) isotopic composition of deposited dust particles, potential sources of different Saharan dust events can be identified. The study of ‘‘red dust’’ events collected in France allowed us to identify distinct North African source areas (e.g. Lybia vs. Mauritania). Surprising...
