Faire le lien entre la chimie et la biologie : conférence les 31 Juin et 1er Juillet à Paris

30 juin – 1 juillet 2011

Conférence organisée par : Centre François Viète, Centre Koyré, Centre Cavaillès, et IHPST
Une initiative du programme interdisciplinaire du CNRS « Environnements Planétaires et Origines de la Vie »
Lieu: Ecole Normale Supérieure, Salle Dussane,  45 rue d’Ulm, 75005 Paris

Contexte : « Chemistry and biology stand on two-sides of a great divide marked by the still un-explained phenomenon of life. Despite the advent of an increasingly chemical biology, especially since the rise of molecular biology in the 1950s, and of an increasingly biological chemistry as shown by the developments of biochemistry, both disciplines remain apart as the transition from non-living to living matter is yet to be solved. Not only is the very nature of life unaccounted for in chemical terms, but the evolutionary processes by which inanimate matter turned into life are still largely unknown. By bringing together a balanced group of scientists, historians and philosophers of science, it is the aim of this conference to explore ways in which the search for the origins of life has helped and is still helping, build bridges in between chemistry and biology ».

Comité d’organisation : Puri Lopez (Université Paris Sud), Christophe Malaterre (IHPST), Michel Morange (Centre Cavaillès), Florence Raulin-Cerceau (Centre Koyré), Stéphane Tirard (Centre François Viète)
