Electrical signaling in biology is typically associated with action potentials, transient spikes in membrane voltage that return to baseline. Hodgkin-Huxley and related conductance-based models of electrophysiology belong to a more general ...
Large and reversible myosin-dependent forces in rigidity sensing [0.03%]
肌动蛋白踏车和肌球蛋白-II对细胞刚性感应的作用力及其可逆变化
James Lohner,Jean-Francois Rupprecht,Junquiang Hu et al.
James Lohner et al.
Cells sense the rigidity of their environment through localized pinching, which occurs when myosin molecular motors generate contractions within actin filaments anchoring the cell to its surroundings. We present high-resolution experiments ...
Stress relaxation in epithelial monolayers is controlled by the actomyosin cortex [0.03%]
上皮单层的应力松弛由肌动蛋白肌球蛋白皮层控制

Epithelial monolayers are one-cell thick tissue sheets that line most of the body surfaces, separating internal and external environments. As part of their function, they must withstand extrinsic mechanical stresses applied at high strain r...
Sixfold enhancement of superconductivity in a tunable electronic nematic system [0.03%]
可调电子各向异性系统中凝聚态物理奇异现象：超导性六倍增强

The electronic nematic phase-in which electronic degrees of freedom lower the crystal rotational symmetry-is commonly observed in high-temperature superconductors. However, understanding the role of nematicity and nematic fluctuations in Co...

Most physical and other natural systems are complex entities composed of a large number of interacting individual elements. It is a surprising fact that they often obey the so-called scaling laws relating an observable quantity with a measu...
Cell swelling, softening and invasion in a three-dimensional breast cancer model [0.03%]
三维乳腺癌模型中的细胞肿胀，软化和入侵

Sculpting of structure and function of three-dimensional multicellular tissues depend critically on the spatial and temporal coordination of cellular physical properties, yet the organizational principles that govern these events, and their...
The way ahead for fusion [0.03%]
通向聚变的道路
As the construction of the ITER tokamak enters its next phase - the machine assembly - now is a good time for a recap of the history and current status of nuclear fusion research. ...

Spin liquids are highly correlated yet disordered states formed by the entanglement of magnetic dipoles1. Theories define such states using gauge fields and deconfined quasiparticle excitations that emerge from a local constraint governing ...
The energy cost and optimal design for synchronization of coupled molecular oscillators [0.03%]
耦合分子振子同步的能耗及最优设计
Dongliang Zhang,Yuansheng Cao,Qi Ouyang et al.
Dongliang Zhang et al.
A model of coupled molecular biochemical oscillators is proposed to study nonequilibrium thermodynamics of synchronization. We find that synchronization of nonequilibrium oscillators costs addition energy to drive the exchange reaction (che...
The role of single cell mechanical behavior and polarity in driving collective cell migration [0.03%]
单细胞机械行为和极性在集体细胞迁移中的作用
