Author(s): Victor Murcia, Obaid Alqahtani, Harlan Heilman, and Brian A. Collins Local molecular orientation and conformation within nanostructures is central to their behavior in devices, emergent quantum states, and biological processes. X-ray microscopy and scattering at the carbon absorption edge is uniquely sensitive to these phenomena, through transition dipole moments enc… [Phys. Rev.

Author(s): Mengfei He, Sungkyu Cho, Gianna Dafflisio, Sitaram Emani, and L. Mahadevan A simplified model of the heart’s mitral valve shows that flow fluctuations can cause a soft valve to close at about one-tenth the pressure required under steady flow. [Phys. Rev.

Author(s): Sergi G. Leyva, Ahis Shrestha, and Monica Olvera de la Cruz Biological systems rely on autonomous modes of charge transport to transmit signals. Instead, conventional synthetic systems typically depend on external fields, such as voltage or pressure gradients, to induce transport, which limits their applicability. Here, we investigate nanochannels in which a… [Phys. Rev. Lett. 137, 148202] Published Wed Sep 30, 2026

Author(s): Shunsuke Saita, Finn Bastian Molzahn, Clara Delahousse, Julien Husson, and Charles N. Baroud Many biological, culinary, and engineering processes lead to the coencapsulation of several soft particles within a liquid interface. In these situations the particles are bound together by the capillary forces that deform them and influence their biological or rheological properties. Here, we intro… [Phys. Rev.

Author(s): C. Reichhardt and C. J. O. Reichhardt Transitions from reversible to irreversible or fluctuating states above a critical density and shear amplitude have been extensively studied in nonthermal cyclically sheared suspensions and amorphous solids. Here, we propose that the same type of reversible to irreversible transition occurs for a sy… [Phys. Rev. Lett. 137, 148201] Published Tue Sep 29, 2026

Author(s): Aranyak Sarkar, Pooja Yadav, and Matthias Weiss The cytoplasm of eukaryotic cells is a complex fluid that harbors a variety of membrane-enveloped organelles with distinct spatial distributions and duties. Peroxisomes, for example, are vesicular entities with radii in the sub-micron range, dispersed all over the cytoplasm to provide oxidative reac… [Phys. Rev.

Author(s): Manh-Quan Nguyen, Alberto Dinelli, Gianmarco Spera, and Julien Tailleur Long-range interactions are ubiquitous in nature, where they are mediated by diffusive fields at the cellular scale or by visual cues for groups of animals. Short-range forces, which are paradigmatic in physics, can thus often be neglected when modeling the collective behaviors of biological systems… [Phys. Rev.
