Linking lineage and population observables in growing cell populations
The question of how a cell controls its size is an one, which despite decades of research is still timely because the old experiments have been unable to measure the heterogeneity of cell populations which can be...
Benoît Sorre (MSC)
Microfabricated tools to study embryonic patterning in vitro
One of the most striking features of embryonic development is that differentiation is happening in a spatially ordered fashion: tissue self-organize to form well-defined patterns that pre-figure the body plan. During...
Philippe Nghe (ESPCI)
Natural selection of compartmentalized autocatalytic chemical reactions
Natural selection, the differential reproduction and survival (differential fitness) of individuals due to differences in phenotype, is an essential component of evolution in biological systems. Understanding how...

Emerging order, from crystals of colloids to fish schools
Living systems constantly exploit active fluctuations in their processes, to boost transport or assist assembly. Self-propelled colloids, that consume energy to move hold the same potential for man-made assembly of...
Barbara Bravi (ENS)
Modelling and predicting antigen presentation with Restricted Boltzmann Machines
Immune recognition of infected and malignant cells requires presentation on their surface of antigens (i.e. short peptides) by human leukocyte antigen class I (HLA-I) proteins, which are coded by one of the most...

Soft Matter for the Origin of Life: Liquid Crystals, Phase Transitions and the Prebiotic Emergence of Biopolymers
The abiotic formation of biopolymers from their monomeric building blocks and the emergence of cellular structures are still unsolved problems in the origin of life investigation. In this frame soft matter concepts...
Olivier Marre (Institut de la vision)
Retinal computations and circuits integrating contextual information
At the retinal output, a common assumption is that ganglion cells of a single type extract a single stimulus feature from the visual scene to form a feature map. Yet they can also respond to very distant...
Florence Débarre (Sorbonne Université)
Can a population targeted by an artificial gene drive be rescued?
Gene drive, a type of genetic control, consists in using selfish genetic elements to modify or eradicate populations. The idea is not new, but has only recently become feasible, thanks to the development of...
Sandrine Etienne-Manneville (Pasteur)
Cytoskeletal crosstalk during cell migration
Cell migration requires a dramatic and coordinated reorganization of the different elements of the cytoplasmic cytoskeleton, composed of three types of filamentous structures: actin microfilaments, microtubules and...
