Actomyosin machinery endows cells with contractility at a single-cell level. However, within a monolayer, cells can be contractile or extensile based on the direction of pushing or pulling forces exerted by their neighbours or on the substrate. It has been shown that a monolayer of fibroblasts behaves as a contractile system while epithelial or neural progentior monolayers behave as an extensile system

Self-repair protects microtubules from destruction by molecular motors Nat. Mater. (IF 38.663) Pub Date : 2021-01-21 Sarah Triclin; Daisuke Inoue; Jérémie Gaillard; Zaw Min Htet; Morgan E.

Microtubule instability stems from the low energy of tubulin dimer interactions, which sets the growing polymer close to its disassembly conditions. Molecular motors use ATP hydrolysis to produce mechanical work and move on microtubules. This raises the possibility that the mechanical work produced by walking motors can break dimer interactions and trigger microtubule disassembly. We tested this hypothesis

Dissipationless currents from topologically protected states are promising for disorder-tolerant electronics and quantum computation. Here, we photogenerate giant anisotropic terahertz nonlinear currents with vanishing scattering, driven by laser-induced coherent phonons of broken inversion symmetry in a centrosymmetric Dirac material ZrTe5. Our work suggests that this phononic terahertz symmetry switching

Hexagonal metal oxide monolayers derived from the metal–gas interface Nat. Mater. (IF 38.663) Pub Date : 2021-01-18 Bao Yue Zhang; Kai Xu; Qifeng Yao; Azmira Jannat; Guanghui Ren; Matthew R. Field; Xiaoming Wen; Chunhua Zhou; Ali Zavabeti; Jian Zhen Ou
Two-dimensional (2D) crystals are promising materials for developing future nano-enabled technologies1,2,3,4,5,6. The cleavage of weak, interlayer van der Waals bonds in layered bulk crystals enables the production of high-quality 2D, atomically thin monolayers7,8,9,10. Nonetheless, as earth-abundant compounds, metal oxides are rarely accessible as pure and fully stoichiometric monolayers owing to

Direct imaging of atomistic grain boundary migration Nat. Mater. (IF 38.663) Pub Date : 2021-01-11 Jiake Wei; Bin Feng; Ryo Ishikawa; Tatsuya Yokoi; Katsuyuki Matsunaga; Naoya Shibata; Yuichi Ikuhara
Grain boundary (GB) migration plays an important role in modifying the microstructures and the related properties of polycrystalline materials, and is governed by the atomistic mechanism by which the atoms are displaced from one grain to another. Although such an atomistic mechanism has been intensively investigated, it is still experimentally unclear as to how the GB migration proceeds at the atomic
