[Biophysics seminar] Clement Zankoc: “Active Instability and Nonlinear Dynamics of Cell-Cell Junctions”
ZoomActive cell-junction remodeling is important for tissue morphogenesis, yet its underlying physics is not understood. We study a mechanical model that describes junctions as dynamic active force dipoles. Their instability can trigger cell intercalations by a critical collapse. Nonlinearities in … Read More
[Biophysics seminar] Toshikaze Chiba: “Deformation and rearrangement of membranes in adhering vesicles”
ZoomVesicle is a molecular assembly configuring lipid bilayer shell, and investigated as a model system of biological cell. Using both experimental observation and minimising the total energy, we study the morphology of lipid vesicle doublet and triplet. We demonstrate that … Read More

[Biophysics seminar] Urška Andrenšek: “The continuum approximation of the vertex model”
ZoomThe continuum-mechanics approach to the vertex model is useful to understand the phenomenology of tissue deformations during morphogenesis. I will review the past attempzs to derive the continuum theory and compare the theoretical results to the results of numerical simulation. … Read More
[Biophysics seminar] Tomer Stern: “Deconstructing Gastrulation at Single-Cell Resolution”
ZoomGastrulation movements in all animal embryos start with regulated deformations of patterned epithelial sheets. Current studies of gastrulation use a wide range of model organisms and emphasize either large-scale tissue processes or dynamics of individual cells and cell groups. In … Read More
[Biophysics seminar] Jaffar Hasnain: “Spontaneous emulsification induced by nanoparticle surfactants”
ZoomMicroemulsions, mixtures of oil, water, and surfactant, are thermodynamically stable. Unlike conventional emulsions, microemulsions form spontaneously, have a monodisperse droplet size that can be controlled by adjusting the surfactant concentration, and do not degrade with time. To make microemulsions, a … Read More
[Biophysics seminar] Gregor Posnjak: “From DNA origami to photonic crystals”
ZoomThe idea of using the predictable base pairing of DNA nucleobases for programmable assembly on the nanoscale dates back to the 1980s when the recently deceased Ned Seeman had the idea of using it to crystalize proteins on a DNA-based … Read More
