Some sound advice on mask efficacy from our friends at the MPI-DS LFBP department! pnas.org/content/118/49… They're passionate about keeping the MPI staff safe and healthy.

A study of our colleague Eberhard Bodenschatz and his group on the effect of masks on coronavirus transmission. Great to see this published in its fully glory after seeing many pieces of it over the last year. pnas.org/content/118/49…

My first preprint: How self-buckling reveals gliding forces of filamentous cyanobacteria. arXiv.org arxiv.org/pdf/2202.13658…

We congratulate our #mattertolife PhD graduate Leila Abbaspour for successfully defending her #phdthesis “Dynamics and Self-organization of Crowded Active Systems”! 🎓🎉 Leila completed her doctorate at Uni Göttingen under the supervision of Stefan Klumpp ‍👏

Leila Abbaspour Rituparno Mandal Active matter exhibits long-range velocity correlations without explicit interactions that align velocities. Here we show (using simulations and analytical arguments) that the same happens in passive matter if it is doped with a small fraction of active particles.

Can an active dopant induce long-range velocity correlations in passive matter?This is the intriguing question we explore in our latest research paper.Rituparno Mandal Stefan Klumpp Check out arxiv.org/abs/2302.13131

Interested in #3Dprinting, #Rheology, and #FluidMechanics ? Our new Journal of Fluid Mechanics article is out today, explaining the deposition of a viscoplastic filament on a surface. we show how yield stress determines the final shape of the printed filament. cambridge.org/core/journals/…

Exciting news! Our paper on how directional reversal affects pattern formation of active filaments is out now in Physical Review Research . Check it out for more information! journals.aps.org/prresearch/abs…. Special thanks to Ali Malek, Stefan Karpitschka and Stefan Klumpp Max Planck School Matter to Life

If you are interested in a generic phase-space description of active particles that will enable accurate implementation of multiplicative noise (i.e. spatial modulation of the strength of noise or fluctuations) this recent work might be something you'd like to look up.

Happy to announce that my latest work got published in Nature Physics. For the first time, we show how a RG calculation gives consistent predictions with experimental data on living systems. You can find the paper here rdcu.be/daCHh.

Excited to share our latest work on the captivating "Interfacial activity dynamics of confined active droplets" now published Journal of Fluid Mechanics A great collaboration with ASM group, Arnold Mathijssen, and Mitya Pushkin. cambridge.org/core/journals/… Physics of Fluids @ UTwente Max Planck Society

Now online: We quantified the gliding forces of filamentous cyanobacteria by self-buckling experiments in microfluidic devices, which led to valuable insight into the still unsolved gliding mechanism. doi.org/10.7554/eLife.… eLife - the journal MPI-DS Göttingen

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…

Hot off the press: In a collaboration between Stefan Karpitschka's group and several people from Living Matter Physics, we show how filament motility, reversals at illumination boundaries and filament interactions work together to create emergent structures.
