L’intestin est une pompe et un réacteur biochimique. Sa longueur (7 m chez l’adulte) garantit une surface d’absorption importante des nutriments et permet de compartimenter la digestion; des mouvements autonomes de...

The pulmonary airway system is a highly hierarchical tree-like 3D network in charge of transferring oxygen from the upper airways down to the alveolar region where the gas exchange occurs between air and blood. It is...

Fungi are ubiquitous in our environment. They are part of the so-called “rare biosphere” of the human microbiota, representing less than 0.1% of the microbiome in healthy individuals. However, fungi may take...

Even though biological tissues are highly dynamic at many different scales, traditional optical microscopes can often enable to track only a portion of them. While the optical diffraction limit prevents the detection...

Variation and selection are the core principles of Darwinian evolution, but quantitatively relating the diversity of a population to its capacity to respond to selection is challenging. Here, we examine this problem...

Shigella is an enteroinvasive bacterium that induces human bacillary dysentery. The delivery of 30 bacterial effectors inside host cells allows the bacteria to invade colon epithelial cells, lyse the membrane of its...

Calcium plays a critical role in several synaptic transduction pathways. We report and discuss here fast calcium transients and how they are possible in dendritic spines. The talk will discuss fast calcium transients...
Sophie Marbach (LPS/ENS)
Filtering specific molecules is a challenge faced for several vital needs: from biomedical applications like dialysis to the intensive production of clean water. The domain has been boosted over the last decades by...

Collective action occurs when individuals work together to provide a collective good. Examples abound in the social and natural sciences: humans collectively build houses, roads, and walls; lions work together to...

Microbes are the most abundant living entities on earth and are key engines that drive earth's biogeochemical cycles. I will first briefly illustrate some of our research activities for better harnessing microbial...
