From biting to engulfment: Target mechanics determines modes of phagocytosis through curvature--actin coupling
Shubhadeep Sadhukhan, Caitlin E. Cornell, Mansehaj Kaur Sandhu +10
Phagocytosis is a core innate immune process that clears targets spanning a wide range of mechanical properties, yet the role of target mechanics in recognition and engulfment rema…
Mode-coupling theory for aging in active glasses: relaxation dynamics and evolution towards steady state
Soumitra Kolya, Nir S. Gov, Saroj Kumar Nandi
Aging refers to the evolution of system properties with waiting time . It is a key feature of glassy dynamics. Recent experiments have demonstrated aging in biological systems…
Phototactic Decision-Making by Micro-Algae
Shantanu Raikwar, Adham Al-Kassem, Nir S. Gov +3
We study how simple eukaryotic organisms make decisions in response to competing stimuli in the context of phototaxis by the unicellular alga . While neg…
Coupling Anisotropic Curvature and Nematic Order: Mechanisms of Membrane Shape Remodeling
Yoav Ravid, Samo PeniÄ, Luka Mesarec +4
This study theoretically investigates how anisotropic curved membrane components (CMCs) control vesicle morphology through curvature sensing, nematic alignment, topological defects…
Maximal response to a mechanical leader at critical group size in ant collectives
Atanu Chatterjee, Tom Tzook, Nir Gov +1
It is widely recognized that biological collectives operate near criticality to amplify their capability of collective response. The peak in susceptibility near criticality renders…
Chemotaxis-Driven Instabilities Govern Size, Shape and Migration Efficiency of Multicellular Clusters
Monika Sanoria, Gema Malet-Engra, Giorgio Scita +2
The collective chemotaxis of multicellular clusters is an important phenomenon in various physiological contexts, ranging from embryonic development to cancer metastasis. Such clus…
