Embryo‐like structures (stembryos) are an innovative tool, but they are hindered by experimental variability and limited developmental potential. DNA methylation is crucial for mammalian development, but its status in stembryo models is poorly characterized.

The effects of channel noise upon sub-threshold and graded voltage signals.
A. The standard deviation of the voltage of the spiking neuron model (stochastic voltage-gated Na+ and K+ channels), a modified model with stochastic voltage-gated Na+ and deterministic voltage-gated K+ channels, a modified model with deterministic ...

Design of two low-voltage sample and hold circuits
In the resent years, there is a trend of reducing the supply voltage of integrated circuits (ICs) due to the decrease in the feature size of complementary metal-oxide-semiconductor (CMOS) process. Reducing the supply voltage is required for reliability issue in advanced CMOS process. Nevertheless, it can also reduce power dissipation.

pH‐mediated activation of the lysosomal arginine sensor SLC38A9
Cells monitor nutrient levels via the lysosomal transporter SLC38A9 to activate the mechanistic target of rapamycin complex 1 (mTORC1). This study reveals that SLC38A9 function is regulated by pH. We identified histidine 544 as a critical pH sensor that undergoes conformational changes to control amino acid efflux from lysosomes; therefore, it ...

Air-independent polymer electrolyte membrane fuel cells (PEMFCs) operate with pure O2 in closed systems, subjecting membrane-electrode assemblies (MEAs) to high O2 activity, prolonged high-voltage idling, and humidity or pressure transients.

Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...
