The Indian subcontinent was the scene of dramatic upheavals a few thousand years ago. The Northwest region entered an arid phase, and erosion coupled with tectonic events played havoc with river courses. One of them disappeared. Celebrated as -Sarasvati' in the Rig Veda and the Mahabharata, this river was rediscovered in the early nineteenth century through topographic explorations by British officials. Recently, geological and climatological studies have probed its evolution and disappearance, while satellite imagery has traced the river's buried courses and isotope analyses have dated ancient waters still stored under the Thar Desert. In the same Northwest, the subcontinent's first urban society"the Indus civilization"flourished and declined. But it was not watered by the Indus alone: since Aurel Stein's expedition in the 1940s, hundreds of Harappan sites have been identified in the now dry Sarasvati's basin. The rich Harappan legacy in technologies, arts and culture sowed the seeds of Indian civilization as we know it now. Drawing from recent research in a wide range of disciplines, this book discusses differing viewpoints and proposes a harmonious synthesis"a fascinating tale of exploration that brings to life the vital role the -lost river of the Indian desert' played before its waters gurgled to a stop.
For thousands of years, political leaders have unified communities by aligning them against common enemies. However, today more than ever, the search for “common” enemies results in anything but unanimity. Scapegoats like Saddam Hussein, for example, led to a stark polarization in the United States. Renowned neuropsychiatrist and psychologist Jean-Michel Oughourlian proposes that the only authentic enemy is the one responsible for both everyday frustrations and global dangers, such as climate change—ourselves. Oughourlian, who pioneered an “interdividual” psychology with René Girard, reveals how all people are bound together in a dynamic, contingent process of imitation, and shows that the same patterns of irrational mimetic desire that bring individuals together and push them apart also explain the behavior of nations.
In the past few years, growing attention has been devoted to the study of the interactions taking place in mixed systems of phospholipid membranes and inorganic nanoparticles. This is an important issue with regard to using nanoparticles in nanomedicine but also in the related field of nanotoxicology. However, the nature of the interactions in such mixtures is rather complex and may lead to the formation of different colloidal structures. Focusing on the case of liposomes and silica nanoparticles, the study presented here aims at improving our understanding of the interactions in such mixed systems and at obtaining a detailed picture of the hybrid structures they result in. Drawing a parallel between different systems, this work offers not only interesting features on the internalization process of nanoparticles and on the stability of nanoparticle–decorated vesicles but also comprehensive insights into the influence of the bilayer state (liquid, gel) on the nanoscale structures of hybrid liposome/nanoparticle complexes.
