  1. 8. Structure and Dynamics of Interphase Chromosomes
    Prof. Ralf Everaers (Laboratoire de Physique et Centre Blaise Pascal, ENS-Lyon et CNRS)

    Matiere molle/Biophysique
    During interphase chromosomes decondense, but fluorescent in situ hybridization experiments reveal the existence of distinct territories occupied by individual chromosomes inside the nuclei of most eukaryotic cells. We use computer simulations to show that the existence and stability of territories is a kinetic effect that can be explained without invoking an underlying nuclear scaffold or...

    Cell adhesion has attracted the attention of physicists and engineers since it has become apparent that (i) managing it is a prerequisite to organize cells in a synthetic matrix for bioengineering applications, and (ii) that it could not be described with theories designed for dead matter, albeit sophisticated they are. The adhesion of cells to their surrounding medium begins with the...

  3. 10. Proteins in the light of evolution

    Matiere molle/Biophysique
    I will present work aimed at deciphering the relation between the sequence and function of proteins based on the principle of co-evolution. By analyzing statistically large numbers of related sequences, we can infer from this principle the patterns of functional couplings between amino acids in a protein. This analysis reveals a decomposition of proteins into evolutionary units that differs...

  4. 11. Graphs and statistics for protein interfaces.
    Dr Giovanni FEVERATI (Laboratoire d'Annecy de physique théorique, CNRS et Université de Savoie)

    Matiere molle/Biophysique
    Living organisms are made of nucleotides (DNA and RNA), lipids and proteins. All biological activities consist in interactions between those different entities. Identifying and rationalizing the interaction modes between partners is therefore crucial for investigating any biological problem. The interactions are encoded by patterns that are not easily inferred due to the large number of...
