We are pleased to announce you that CENTURI 2021 Scientific meeting (CSM2021) will be devoted to “Information networks in biological systems”. It will take place from October 18 to October 22, 2021, at the Institut d'Études Scientifiques de Cargèse in Corsica, France. Each year, CENTURI gathers leading scientists from all over the world to tackle interdisciplinary and contemporary challenges in biology, physics, mathematics and computer science. CENTURI 2021 Scientific meeting will focus on how information networks underlie the organisation and dynamics of biological systems with examples in the fields of cell and developmental biology, neuroscience, immunology and social behaviour. Research in the past couple of decades have shown that biological information can be encoded not only biochemically but also in the mechanics of a system. Length and time scales of a system can emerge from cross-talk between its physical and biochemical properties. Moreover, the geometry of the space in which mechano-chemical information flows is itself informative: networks of information are spatially defined, which may dictate how molecules, cells and organisms self-organise. This conference will bring together a diverse set of scientists in biology, physics and computer science to discuss these questions. We believe that our conference is a unique opportunity to foster new collaborations and exchange about a wide range of topics in life sciences and we would be glad to welcome you there.
