Systematic mapping of cell wall mechanics in the regulation of cell morphogenesis
Abstract: Walled cells of plants, fungi, and bacteria come with a large range of shapes and sizes, which are ultimately dictated by the mechanics of their cell wall. This stiff and thin polymeric layer encases the plasma membrane and protects the cells mechanically by opposing large turgor pressure derived mechanical stresses.

Modulation of tissue growth heterogeneity by responses to mechanical stress
Publication from the Laboratoire Reproduction et développement des plantes (RDP) in the journal Proceedings of the National Academy of Sciences USA (PNAS) on January 23, 2019. Abstract:  Morphogenesis often yields organs with robust size and shapes, whereas cell growth and deformation feature significant spatiotemporal variability.

A model for describing the hydrodynamics of crowds
By studying the movement of runners at the start of marathons, researchers from the Laboratoire de physique (CNRS/ENS de Lyon/UCBL) have just shown that the collective movements of these crowds can be described as liquid flows. Their results, published in Science on January 4, 2019, have enabled them to predict how fluctuations in speed and density are transmitted through massive crowds.
