Lymphocyte-specific protein 1 regulates mechanosensory oscillation of podosomes and actin isoform-based actomyosin symmetry breaking OPEN
Pasquale Cervero, Christiane Wiesner, Anais Bouissou, Renaud Poincloux & Stefan Linder

The actomyosin cytoskeleton plays an important role in polarised cell migration. Here the authors identify lymphocyte-specific protein (LSP)-1 as a regulator of actomyosin contractility in macrophages, by competing with supervillin for myosin IIA activators acting specifically on the β-actin isoform.

Evidence of a one-dimensional thermodynamic phase diagram for simple glass-formers OPEN
H. W. Hansen, A. Sanz, K. Adrjanowicz, B. Frick & K. Niss

Glass formers show dynamics over a broad range of timescales, presenting a hurdle to understanding the glass transition. Here, the authors find that the dynamics of glass-forming liquids are governed by the same mechanisms over different timescales, effectively reducing the phase diagram from two to one dimension.

Higher-generation type III-B rotaxane dendrimers with controlling particle size in three-dimensional molecular switching OPEN
Chak-Shing Kwan, Rundong Zhao, Michel A. Van Hove, Zongwei Cai & Ken Cham-Fai Leung

The complexity of rotaxane dendrimers poses a great synthetic challenge and the synthesis of higher generation rotaxane dendrimers has therefore rarely been reported. Here the authors report the synthesis of acid-base switchable rotaxane dendrimers up to generation 4 and demonstrate the uptake and release of guest molecules.

Elucidation of the origin of chiral amplification in discrete molecular polyhedra OPEN
Yu Wang, Hongxun Fang, Ionut Tranca, Hang Qu, Xinchang Wang, Albert J. Markvoort, Zhongqun Tian & Xiaoyu Cao

The sergeants-and-soldiers effect, in which a few chiral units induce chirality in a large number of achiral molecules, is difficult to quantify at the molecular level. Here, the authors devise an elegant strategy—combining theory and a system of pure organic polyhedra with chiral and achiral vertices—to understand the mechanism of chiral amplification in discrete molecular assemblies.
