Super happy to see my first PhD work out in @PNASNews, describing analytically how geometry affects gliding motility! Big thanks to everyone, especially my supervisor @SchwarzUlrich (read his thread!) and Mirko and Freddy from @FrischknechtLab. Read here: doi.org/10.1073/pnas.2…

New paper out in @PNASNews: how is gliding motility of microorganisms like malaria parasites determined by cell shape and surface flow? Great work by fabulous PhD-student @LeonLettermann, with Falko Ziebert and inspiration by @FrischknechtLab, @clhueschen and @TardieuXlab. 1/9

A phase field model of a crawling cell captures cell motility patterns observed experimentally on confined substrate geometries. It describes how larger, softer epithelial cells hop more persistently while smaller, stiffer cells remain bistable. 🔗 go.aps.org/4gLVi3O

Happy to share the latest work from @DrPreetiSahuPhD, with @ASanchezDanes on the biomechanics of cell fate choices during tumor initiation! We implement/test a 3D vertex model with proliferation and fate choices for multilayered tissues! 🧵below (1/n) bit.ly/3ZXxJzk

Made with #blender, very handy for shiny visualization of complex (e.g. 3D) data, here the trajectories of malaria sporozoites moving through a hydrogel! Great experiments by Mirko Singer at @FrischknechtLab , we tracked the sporozoites and rendered the resulting trajectories!

The 2025 calendar of the German Research Foundation (DFG) is out dfg.de/de/aktuelles/p… Congrats to @LeonLettermann, whose picture of malaria parasites was selected for November. Imaging data from @FrischknechtLab, funding from DFG priority programme 2332 @ParasitePhysics.

Analytical calculations and numerical sampling reveals the effects of spatially disordered growth on buckling instability of elastic rods, showing how biological systems could trigger or avoid buckling and thereby control a key driver of morphogenesis. 🔗 go.aps.org/4f6C2xr

Hot off the press: In a collaboration between Stefan Karpitschka's group and several people from @LivMatPhys, we show how filament motility, reversals at illumination boundaries and filament interactions work together to create emergent structures. @Lei_La_ @RGolestanian @mpids
Nature Communications@NatureComms

Kurjahn et al. show that filamentous #cyanobacteria use light gradients and boundary curvature of light stimuli to form to form ordered, entangled #aggregates, revealing how these dynamics could influence adaptive colony architectures #microorganisms nature.com/articles/s4146…

A general mechanism of left-right symmetry breaking is observed in epithelial spheres, highlighting the subtle interplay between geometry, topology, and collective dynamics in living #tissue. Read the paper: go.aps.org/3ysH3Ar

Paper alert: nature.com/articles/s4156… @NatureMaterials introduces the “Mean Back Relaxation” which quantifies non-equilibrium from simple passive particle trajectories. Amazing theory (M. Krüger, G.Knotz) and experiments @MunkerTill to obtain cell mechanics by simple observation🧐
