Description
This session will focus on applications of soft matter concepts and other methods from statistical physics to problems of biological interest, from cell adhesion to chromosome dynamics or protein structures.

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...

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...

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...
