Simple self-replicators: growth via self-assembly and fissioning via bursting bubbles
We explore the principles of and experimentally demonstrate an autonomousand natural scheme for molecular self-replication. The talk will discuss a design for a simple DNA self-replicator that in principle exhibits...

A blueprint for actomyosin assembly and disassembly during pulsed contractions: imaging single molecules in a developing embryo
Actomyosin-based pulsed contractions are a widespread and highly dynamic form of self-organized contractility that underlies numerous morphogenetic events during early development. However the mechanisms that govern...

Efficient coding in recurrent networks
Cortical responses are hugely variable and heterogeneous. Moreover, the brain is amazingly robust, able to withstand lesions and neural deaths with minimal impact on behavior. But does that really matter, given than...

The biophysical basis of morphogenesis: symmetry breaking and elongated forms in plants and fungi
Despite extensive research, we are far from a comprehensive answer to the question of how cells and organisms adopt well-defined shapes. We addressed this question in the context of symmetry breaking and stationary...

IN VITRO STUDY OF LEUKOCYTES RECRUITMENT EVENTS
During the immunological response, circulating leukocytes are recruited from the blood system towards inflammatory zones via a complex cascade of events: after exiting the capillary bed, leukocytes stop by adherence...

Intrinsic and extrinsic determinants of axon growth and lamination in retinal ganglion cells
Retina Ganglion Cells axons project from the eye to the contralateral optic tectum. We will present data illustrating the importance of axonal transport to regulate axon growth via an homeostatic. We have analyzed...

Mécano-sensibilité des cellules vivantes: rôle de la rigidité de l'environnement sur la migration cellulaire.
Les forces mécaniques jouent un rôle important dans la croissance et la formation des tissus et des organes qui composent notre corps. La perception qu'ont les cellules vivantes de leur environnement mécanique...
