• Author(s): Rodrigo Soto, Martín Pinto, and Ricardo Brito Active Brownian particles can be described by a Boltzmann–Enskog-like kinetic theory in which a motility-induced phase separation could arise from a reduced effective velocity of particles.

Krastev, Giovanni Polverino, Sauro Succi, and Maurizio Porfiri A deep-sea sponge’s intricate skeleton converts the horizontal flow of ocean currents into a vertical flow through the sponge’s body—a mechanism that helps with the sponge’s filter feeding.

Ediger The structural and segmental relaxation times in a deformed polymer glass are similar, indicating a connection between segmental mobility and structural relaxation. [Phys. Rev.

  • Author(s): Chinmay Katke, Peter A. Korevaar, and C. Nadir Kaplan Acid-induced release of stored ions from polyacrylic acid hydrogels (with a free surface fully permeable to the ion and acid) was observed to increase the gel osmotic pressure that leads to rapid swelling faster than the characteristic solvent absorption rate of the gel. The subsequent equilibration… [Phys. Rev. Lett. 132, 208201] Published Wed May 15, 2024
  • Author(s): Omkar Hegde, Tianhao Li, Anjali Sharma, Marco Borja, William M. Jacobs, and W. Benjamin Rogers In many biopolymer solutions, attractive interactions that stabilize finite-sized clusters at low concentrations also promote phase separation at high concentrations. Here we study a model biopolymer system that exhibits the opposite behavior, whereby self-assembly of DNA oligonucleotides into finit… [Phys. Rev. Lett. 132, 208401] Published...
  • Author(s): Shao-Zhen Lin, Rishita Changede, Aaron J. Farrugia, Alexander D. Bershadsky, Michael P. Sheetz, Jacques Prost, and Jean-François Rupprecht Cell adhesion receptors are transmembrane proteins that bind cells to their environment. These proteins typically cluster into disk-shaped or linear structures. Here, we show that such clustering patterns spontaneously emerge when the receptor senses the membrane deformation gradient, for example...
  • Author(s): Ryan R. Keogh, Timofey Kozhukhov, Kristian Thijssen, and Tyler N. Shendruk While bacterial swarms can exhibit active turbulence in vacant spaces, they naturally inhabit crowded environments. We numerically show that driving disorderly active fluids through porous media enhances Darcy’s law. While purely active flows average to zero flux, hybrid active/driven flows display … [Phys. Rev.
