Author(s): Takahiro Sakaue and Enrico Carlon Active polymers are ubiquitous in nature, and often kicked by persistent noises that break detailed balance. In order to capture the out-of-equilibrium dynamics of such active polymers, we propose a simple yet reliable analytical framework based on a compounding formula. Connecting polymeric dynamic… [Phys.

Author(s): Yafei Zhang, Michael Moshe, and Eran Sharon Geometric incompatibility, the inability of a material’s rest state to be realized in Euclidean space, underlies shape formation in natural and synthetic thin sheets. Classical Gauss and Mainardi-Codazzi-Peterson incompatibilities explain many patterns in nature, but they do not exhaust the mechanis… [Phys. Rev. Lett. 137, 058201] Published Tue Jul 28, 2026

Author(s): K. R. Prathyusha, Paulami Sarkar, Justin Xu, and Saad Bhamla Living organisms employ diverse strategies to navigate confined environments. Inspired by translocation observations on California blackworms (Lumbriculus variegatus), we combine biological experiments and active-polymer simulations to examine how confinement and stiffness govern translocation. Acti… [Phys. Rev. Lett. 137, 058302] Published Tue Jul 28, 2026

Author(s): Takehiro Tottori and Tetsuya J. Kobayashi Organisms adapt to volatile environments by integrating sensory information with internal memory, yet their information processing is constrained by resource limitations. Such limitations can fundamentally alter optimal estimation strategies in biological systems. For example, recent experiments sug… [Phys. Rev. Lett. 137, 058401] Published Tue Jul 28, 2026

Author(s): Marta Grasa, Laciel Alonso-Llanes, Angel Garcimartín, and Iker Zuriguel We present experimental results of the flow of programmable robots through a bottleneck. With these agents, velocity and force can be decoupled—a unique feature allowing us to show that, in the absence of physical contact and pushing from behind, and despite the development of clogs, moving faster a… [Phys.

Author(s): Alessandra Lucchetti, Lukas H. Kristensen, Mogens H. Jensen, and Mathias S. Heltberg Oscillations constitute a defining feature of nonequilibrium processes of life. We analyze a minimal degradation-mediated negative feedback loop, in which the final species in a linear cascade enzymatically degrades the first component. By coupling mean-field ordinary differential equations with a p… [Phys. Rev. Lett. 137, 048401] Published Wed Jul...

Author(s): Yichen Yan (颜逸辰) and Jie Lin (林杰) The relationship between protein and messenger RNA (mRNA) levels is a key aspect of gene expression. Although a strong mRNA-protein correlation is widely observed, the evolutionary force driving the correlation remains poorly understood, undermining the reliability of using mRNA abundance as a proxy… [Phys.
