  • Interaction of active matter with geometrical and topological constraints is a topic of intense research in the recent few years due to its potential for design and control of active flow patterns. Here, the authors experimentally study the growth and expansion of cell aggregates interleaved by passive colloidal particles, showing that inert particles can reshape the collective pattern formation in cellular aggregates.

  • Meningococci remodel the plasma membrane of host cells during infection. Here, Charles-Orszag et al. show that plasma membrane remodeling occurs independently of F-actin, along meningococcal type IV pili fibers, by a physical mechanism that they term ‘one-dimensional’ membrane wetting.

  • Condensates with a shell can be formed by liquid-liquid phase separation and can burst like viscous bubbles by nucleation and growth of a hole in the shell surrounded by a rim. The authors develop a model to extract a broad range of rheological properties for spherical shells to understand the conditions for bursting.
