Author(s): Shihe Zhang, Huihan Bao, and Heng Xu Understanding stochastic gene transcription requires distinguishing between intrinsic molecular randomness and extrinsic environmental variability. Traditionally, these components are identified as the independent and correlated fluctuations between identical gene copies within the same cell. Howeve… [Phys. Rev.

Author(s): Lishuai Jin and Martin van Hecke Avalanches are rapid cascades of rearrangements driven by cooperative flipping of hysteretic local elements. Here, we show that flipping dynamics and race conditions—where multiple elements become unstable simultaneously—give rise to dynamic avalanches that cannot be captured by static models of int… [Phys.

Author(s): Luc Zorrilla, Antoine Allard, Krish Desai, and Marco Polin Using a tipless AFM cantilever to selectively block hydrodynamic coupling between flagella of a single cell reveals a subtle balance of the intracellular forces and hydrodynamic interactions that underlies the coordination of flagella within a single-cell microswimmer.

Author(s): Dalin Zhang, Yan Feng, Xiaona Xu, Keqiang Jia, Ramya Emusani, Zhao-Yang Zhang, Jieyi Zhang, Xin Zuo, Zhibin Zhao, Tao Li, Liang Ma, and Dong Xiang Photoisomeric azobenzene derivatives with distinguished conductance in trans and cis states have gained extensive attention for their potential application in fabricating light-controlled electronic switches, which, however, faces great challenges due to the quenching effect once they are...

Author(s): Matthew Reynolds, Daniel L. Baker, Peter D. Olmsted, and Johan Mattsson We show how dynamic heterogeneities (DHs), a hallmark of glass-forming materials, depend on chain flexibility and chain length in polymers. For highly flexible polymers, a relatively large number of monomers (${N}_{c}∼500$) undergo correlated motion at the glass transition temperature (${T}_{g}$), i… [Phys. Rev.

Author(s): Lila Séguy, Axel Huerre, and Suzie Protière We performed experiments to directionally freeze agar hydrogel drops on a copper substrate maintained at low temperature. Unlike the water droplets studied in the literature, where the liquid part can reorganize during freezing, these droplets present a strictly vertical expansion. This is due to th… [Phys. Rev.
