Micron-sized spherical shells made up of a few hundred cells spontaneously rotate when embedded in a gel. New research explains why, and it could lead to better understanding of other collective cell movements. go.aps.org/46GKfov

How do #bacteria navigate tight spots? Coordinated #flagella movement — like a tug-of-oars on the opposite ends of the bacteria — enables efficient navigation in constrained environments, this study suggests. Dive into the paper: go.aps.org/4deN4zi

How Migration May Stabilize the Diversity of Ecosystems physics.aps.org/articles/v17/1… My Physics Magazine "Viewpoint" on work by Giulia Lorenzana, Ada Altieri, and Giulio Biroli in PRX Life

Tools from statistical physics shed light on important ecology problem: how complex ecosystems maintain their stability. Work by Giulio Biroli, Ada Altieri, and Giulia Lorenzana. go.aps.org/3WM3ybG

Stationary, crescent, or... lightning? ⚡ This study used #quantitative cost analysis to show that Physarum polycephalum, a network-forming #microorganism, reorganizes into a new lightning-shaped state adapted to balance building versus transport costs. go.aps.org/3YpJTAz

Measuring actin filament dynamics in #microfluidics experiments reveals the molecular processes of filament breakdown. Profilin and cofilin bind simultaneously to accelerate filament breakdown, while twinfilin competes with profilin but not cofilin. 📝 go.aps.org/4f4uSKm

#DYK that pancreas-derived #organoids show persistent rotation, axis drift, and arrest? The theoretical analysis, combined with live #microscopy, reveals the biophysical mechanisms behind this left-to-right #symmetry breaking. Check it out: go.aps.org/3ysH3Ar

Scientists uncovered universal features in homing trajectories by studying a self-propelled robot. In their experiments and models, the robot reoriented several times before homing time stabilized, showing the robustness of this #AnimalBehavior. 🔗 go.aps.org/3M2ILeL

This study presents a new mechanism of long-distance #GeneRegulation. In this proposed model, insulators bind weakly to nearby chromatin, preventing enhancers from randomly activating unwanted genes. Read the paper: go.aps.org/3AwmVOy
