Our paper on the adaptation of populations in a fluctuating environment is out. In it, we study a generic Pareto-optimal trade-off, between the risk of extinction and the average growth of the population : biorxiv.org/content/10.110…

Here, we provide more details on our scenario on the emergence of homochirality in complex chemical networks (see PNAS 2021). Using various methods (in particular random matrices), we argue that the transition should be robust : royalsocietypublishing.org/doi/10.1098/rs…

pretty cool article on OoLEN member Ryo Mizuuchi (水内 良)’s March paper on the #OriginOfLife by Quanta Magazine Yasemin Saplakoglu ! quantamagazine.org/in-test-tubes-…

Our paper on the adaptation of populations to fluctuating environments is now out in J. Stat. Mech. In it, we study a general trade-off between the risk of population extinction and the growth of the population : doi.org/10.1088/1742-5… via IOPscience

Tomorrow, I give a talk on 'Stochastic thermodynamics of cell division' at a Stochastic Thermodynamics conference organized in Bangalore in memory of the great Prof. Jayannavar : icts.res.in/discussion-mee…

This is a complete and pedagogical account of the recent progresses made in Non-equilibrium Thermodynamics, which hopefully will contribute to make this difficult but important topic more accessible : cambridge.org/core/books/sta…

Very happy to announce that my PhD student Arthur Genthon will defend his thesis next Friday Oct 14th on "Fluctuations in cell lineages and population tree: a thermodynamic perspective". The thesis will be broadcasted on zoom at 3pm from ESPCI Paris.

Our paper on adaptive strategies in Kelly's model is now out. In it, we show how a gambler can exploit past race results and information provided by the bookmaker to build an optimal strategy. We discuss some implications for evolutionary biology. iopscience.iop.org/article/10.108…

Very please to announce that my PhD student (co-supervised with U. Gerland) Gabin Laurent will defend soon his thesis "A statistical view on the origin of homochirality". The thesis will be broadcasted on zoom on Nov 9th at 2pm from ESPCI Paris.

Our preprint on the impact of incomplete lineages on the statistical analysis of cell lineages is out : arxiv.org/abs/2305.05406 In it, we also show how to estimate fitness and death rate or quantify selection from experimental data of cell lineages.

I am pleased to advertise this workshop on climate issues organized near Paris mainly for students, which can be followed online (but the deadline to register is today) indico.ijclab.in2p3.fr/event/9336

Actually, the registration will be opened after today.

Our preprint on the thermodynamics of autocatalytic chemical networks is out now: arxiv.org/abs/2306.02366 In it, we show that there is a minimal topology-dependent energetic cost for running an autocatalytic network.

How to analyse population experiments in which some lineages end prematurely ? Can we disentangle selection effects from survival effects ? To find out, see our recent paper now out in PRX Life : journals.aps.org/prxlife/abstra…

How is the emergence of biological asymmetry related to that of the first polymers ? Here, we propose a scenario where homochirality is assisted by template-directed ligation and polymerization in a non-equilibrium RNA reactor: arxiv.org/abs/2311.04677

What is the risk-return trade-off in Kelly's gambling and why is it relevant to understand the process of growth and adaptation of biological systems in an uncertain environment ? To find out, check our latest preprint : biorxiv.org/content/10.110…

We are organizing a week of lectures on March 4th at ESPCI "Some basic science questions raised by adaptation to climate change". Program and registration for students of PSL university at psl-week.psl.eu/LISTE-DES-PSL-… . Lectures in french can be followed remotely upon request.

Pleased to participate in a concert-conference on the Music of science on May 13th at 8pm. The concert is the result of a collaboration between 4 researchers and 4 composers, and will feature original music composed for this event: sites.google.com/view/muse-ic.

We are organizing a colloquium to celebrate the 200th anniversary of Sadi Carnot's publication on the second law of thermodynamics. This will take place at the Ecole Polytechnique from September 16 to 18, 2024 (registration required before August 31th) : carnot-legacy.sciencesconf.org
