This synthesis presents the most important disruptions of conceptions about the thymus since its discovery in Antique Greece. For centuries, the thymus has been considered as a vestigial organ, and its role in T-lymphocyte differentiation has been proposed only in the 1960’s. Most recent studies attribute to the thymus an essential and unique role in the programming of central immunological self-tolerance. The basal mechanism implicated in this function is the transcription in thymic epithelium of genes encoding precursors of self-antigens. Processing of these latters leads to presentation of self-antigens by the major histocompatibility complex (MHC) machinery expressed by thymic epithelial and dendritic cells. During fetal life, this presentation drives negative selection of T-cell clones harboring receptors with high affinity for these complexes MHC/self-antigen. After birth, this presentation promotes the generation of regulatory T cells specific for these complexes. A number of studies, as well as the identification of Aire and Fezf2 genes, have shown that a thymus dysfunction plays a crucial role in the development of organ-specific autoimmunity. [less ▲]

Lorsque Spacewar!, considéré comme un des premiers jeux vidéo, voit le jour en 1962 dans les salles du Massachussets Institute of Technology, il marque le début d’une longue relation entre ce médium et la science-fiction. À l’heure où l’informatique est encore fort peu micro, la thématique spatiale que ce précurseur exploite présente en effet un avantage certain : celui de déployer à l’écran un « espace dont la principale caractéristique est le vide [...] un lieu qui exige moins de puissance de calcul » (Triclot, 2011). De l’émergence de cette culture hacker dans les années 1960 à la production actuelle, le jeu vidéo a constamment puisé dans les ressorts propres à la science-fiction – que ce soit les accents cyberpunk d’un Deus Ex : Human Revolution (Square Enix, 2011), l’uchronie d’un Wolfenstein : The New Order (Bethesda Softworks, 2014) ou encore la dystopie constitutive d’un Bioshock (2K Games, 2007). Cette richesse spécifique a pourtant été peu interrogée. [less ▲]

A stumbling block to the adoption of silvoarable agroforestry systems is the lack of quantitative knowledge on the performance of different crops when competing for resources with trees. In North-Western Europe, light is likely to be the principal limiting resource for understorey crops, and most agronomic studies show a systematic reduction of final yield as shade increases. However the intensity of the crop response depends on both the environmental conditions and the shade characteristics. This study addressed the issue by monitoring winter wheat (Triticum aestivum L.) growth, productivity and quality under artificial shade provided by military camouflage shade-netting, and using the Hi-sAFe model to relate the artificial shade conditions to those applying in agroforestry systems. The field experiment was carried out over two consecutive years (2013–14 and 2014–15) on the experimental farm of Gembloux Agro-Bio Tech, Belgium. The shade structures recreated two shade conditions: periodic shade (PS) and continuous shade (CS), with the former using overlapping military camouflage netting to provide discontinuous light through the day, and the latter using conventional shade cloth. The experiment simulated shading from a canopy of late-flushing hybrid walnut leaves above winter wheat. Shading was imposed 16 (2013–14) and 10 (2014–15) days before flowering and retained until harvest. The crop experienced full light conditions until the maximum leaf area index stage (LAImax) had been reached. In both years, LAI followed the same dynamics between the different treatments, but in 2013–2014 an attack of the take-all disease (Gaeumannomyces graminis var. tritici) reduced yields overall and prevented significant treatment effects. In season 2014–15 the decrease in global radiation reaching the crop during a period of 66 days (CS: – 61% and PS: – 43%) significantly affected final yield (CS: – 45% and PS: – 25%), mainly through a reduction of the average grain weight and the number of grain per m2. Grain protein content increased by up to 45% under the CS treatment in 2015. Nevertheless, at the plot scale, protein yield (t/ha) did not compensate for the final grain yield decrease. The Hi-sAFe model was used to simulate an agroforestry plot with two lines of walnut trees running either north-south or east-west. The levels of artificial shade levels applied in this experiment were compared to those predicted beneath trees growing with similar climatic conditions in Belgium. The levels used in the CS treatment are only likely to occur real agroforestry conditions on 10% of the cropped area until the trees are 30 years old and only with east-west tree row orientation.

Assorti d’une série de textes inédits, cet ouvrage monographique vise à faire connaître dans le milieu francophone les écrits d’Aby Warburg (1866-1929), en particulier ceux rédigés dans les dernières années de sa vie. Peu connus, ces textes datent de la période d’élaboration de l’Atlas d’images Mnemosyne – Atlas dont le succès grandissant auprès des artistes et des théoriciens de l’art n’est plus à démontrer . Mais si Mnemosyne attire de plus en plus les spécialistes des images de tous horizons, on accorde encore peu d’intérêt aux textes et aux notes rédigées par son auteur dans les années 1926-1929. Ces textes auraient du accompagner les planches de l’Atlas si le projet avait abouti. Or, les manuscrits inédits conservés au Warburg Institute (Londres) montrent la portée philosophique des recherches tardives d’Aby Warburg. Il y développe une théorie culturelle de l’image pour le moins originale et qui a profondément influencé certaines démarches plus contemporaines (dans les domaines de l’histoire de l’art, de l’anthropologie du visuel, de la Bildwissenschaft allemande ou des Visual Studies anglo-saxonnes). À l’occasion d’un débat avec les pensées de Nietzsche et de Burckhardt, Warburg élabore une conception nouvelle de la Kultur. [less ▲]
