L'équipe Minc a publié un nouvel article dans Current Biology : Cell division: Size-scaling cytoplasmic flows transport chromosomes to the right spot   Résumé : Early embryos undergo rounds of division, producing cells of reducing sizes that must scale the distance chromosomes segregate. A new study shows that this scaling results from a cell-size-dependent dampening of cytoplasmic flows…

L'équipe Minc a publié un nouvel article dans Journal of the royal society interface : Dynamic clamping induces rotation-to-beating transition of pinned filaments in gliding assays Résumé : We used numerical simulations to investigate how properties of motor proteins control the dynamical behaviour of driven flexible filaments. A filament on top of a patch of anchored motor proteins…

La plateforme ProtéoSeine a contribué à la publication d'un nouvel article dans Rapid Communications in Mass Spectometry : Electron Transfer Dissociation and Synchrotron UV Photodissociation of Trapped Sodiated Ions Produced From Polyacrylates by Electrospray Ionization   Résumé : Rationale Poly (acrylates)s can be distinguished from one another by the nature of their side chains. From model poly (acrylates)s, the…

L'équipe Ladoux/Mege a publié un nouvel article dans PNAS : Flocking and giant fluctuations in epithelial active solids Significance During embryonic development and wound healing, epithelial cells usually display in-plane polarity over large spatial scales and move coherently. However, most in vitro studies have examined the fluid-like chaotic dynamics of epithelial cells, in which collective cellular flows…
