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): 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.

Author(s): Yongming Zhang, Qingyu Qu, Qian-Yuan Tang, and Xiaoguang Ma By extracting spin configurations directly from a colloidal monolayer mimicking a 2D Ising lattice, entropy scaling laws for liquids and glasses are extended to the domain of spin systems, revealing a universal exponential relationship between configurational entropy and spin relaxation time.

Author(s): Alex Chen Yi Zhang, Pablo Mateu Hoyos, David Brückner, and Gašper Tkačik In many developmental systems, cells differentiate into a tissue by reading out morphogen concentration fields, a process fundamentally limited by noise. How much can the precision of this process be improved by nonlocal information, e.g., via cell-cell communication? Using a Bayes-optimal framework… [Phys. Rev.

Author(s): Md. Shahriar Hossain Shuvo, Xing He, Mithun Ghosh, and Ding-Shyue Yang We report dynamic energy transport across multicomponent molecular junctions observed at the atomic level. A clear temporal sequence of energy transfer is revealed at early times following photoexcitation of Au(111) bonded with self-assembled monolayers of alkanethiols: from the gold surface layer t… [Phys.
