This paper focuses on new paleontological discoveries that have come to light while working on a Permian "paieobotanical" transect. from Oman to Central Morocco, In the Huqf area, the continental plant bearing "Gharif" Formation is bracketed by two welt dated marine Formations, providing new age constraint for the discovered "mixed" paleoHora, The newly named KubergarH;Jian'Murgabian "Gharif Paleoflora" is of outstanding paleogeographic .ignificance, Gondwanan, Cathaysian and Euramerian elements are found to be associated, The understanding of the kinematics of the Permian vegetal cover lead us to test the proposed Peri-Tethyan paleogeographical contours

The emergence of omics technologies allowing the global analysis of a given biological or molecular system, rather than the study of its individual components, has revolutionized biomedical research, including cardiovascular medicine research in the past decade. These developments raised the prospect that classical, hypothesis-driven, single gene-based approaches may soon become obsolete. The experience accumulated so far, however, indicates that omic technologies only represent tools similar to those classically used by scientists in the past and nowadays, to make hypothesis and build models, with the main difference that they generate large amounts of unbiased information. Thus, omics and classical hypothesis-driven research are rather complementary approaches with the potential to effectively synergize to boost research in many fields, including cardiovascular medicine. In this article we discuss some general aspects of omics approaches, and review contributions in three areas of vascular biology, thrombosis and haemostasis, atherosclerosis and angiogenesis, in which omics approaches have already been applied (vasculomics).

Geographical scale is not merely a technical question. The learning of geographical scale goes beyond geometricunderstanding; it implies the etymological comprehension of the concept, the recognition of the importance of scale in theelaboration of the geographical discourse. It implies placing oneself in the centre of the teaching and learning of Geographyand asking oneself, what scale? Why this scale? What progression of scales? The answer to these questions puts in doubtthe scientific discourse that is presently taught in schools especially on the scale of analysis, the sequencing of studiedspaces and the false dichotomy local and global
