RNA interference and nonviral targeted gene therapy of experimental brain cancer
According to isotopic labeling experiments, most of the carbon used by truffle (Tuber sp.) fruiting bodies to develop underground is provided by host trees, suggesting that trees and truffles are physically connected. However, such physical link between trees and truffle fruiting bodies has never been observed.We discovered fruiting bodies of Tuber aestivum adhering to the walls of a belowground quarry and we took advantage of this unique situation to analyze the physical structure that supported these fruiting bodies in the open air. Observation of transversal sections of the attachment structure indicated that it was organized in ducts made of gleba-like tissue and connected to a network of hyphae traveling across soil particles.Only one mating type was detected by PCR in the gleba and in the attachment structure, suggesting that these two organs are from maternal origin, leaving open the question of the location of the opposite paternal mating type

Émile Gallé, botaniste et scientifique
Une des sources essentielles de l’inspiration artistique d’Émile Gallé a été la flore à laquelle il vouait un véritable culte. L’idée de s’inspirer de modèles botaniques n’est pas nouvelle dans l’histoire de l’art. Mais Émile Gallé a renouvelé l’art décoratif en étudiant la nature en savant, en artiste et en poète. Jusqu’à sa mort, il a tenté de percer les secrets de la vie en l’analysant avec la rigueur du scientifique. Ayant ainsi compris sa complexité et sa beauté, l’artiste l’a contemplée mieux que tout autre avec des yeux d’amant. Gallé, le poète, a transcendé la nature par le verbe et lui a donné une nouvelle forme en pétrissant la terre, en maîtrisant le verre et en façonnant le bois
