Combining micropatterning, traction force microscopy, and optogenetics, it is shown that epithelial cells actively respond to mechanical signals from neighboring cells.

A fly larval mechanical nociceptor develops dedicated neuronal mechanisms to support its sensory preference in detecting localized poking forces, and this sensory feature well supports the physiological function of the nociceptor in sensing the physical attack of its natural enemy.

Cell culture adaptation of SARS-CoV-2 is prevented on human airway cells with an active serine protease-mediated entry pathway, allowing the production of genetically stable virus stocks for laboratory experiments.

Detailed studies of excitation contraction coupling allowed determination of quantitative relationships between resting potential, generation of action potentials, conduction of action potentials, and generation of Ca²⁺ transients in individual mouse skeletal muscle fibers.

Purinergic signaling controls mammalian sperm transport.

Laser trap measurements show that mechanical work output from curling protofilaments is enhanced by adding magnesium, and that yeast microtubules generate larger and more energetic working strokes than bovine microtubules.

Precise control of microtubule architecture greatly increases the force that the spindle can exert on chromosomes.

Studies of bacterial chemotaxis reveal how limitations in single-cell sensing of stimuli influence large-scale population morphology.

Increasing muscle length, rather than increasing stretch amplitude, contributes more to residual force enhancement during submaximal voluntary contractions of the human quadriceps.

Advanced machine learning based brain signal decoding of grip-force as a proxy for movement vigor shows Parkinson's disease related performance reduction, suggestive of a loss of cortical vigor encoding in the absence of dopamine.
