The diguanylate cyclase activity of SiaD is activated by its binding partner SiaC thourgh a dynamic mechanism of promoting the formation of active SiaD dimers.
The readiness potential—a long-established neural precursor of voluntary action claimed to precede the onset of the conscious decision to move—is absent, or at least significantly reduced, for deliberate decisions.
Smad and Schnurri transcription factors engage in context-dependent interactions as well as independent genomic activities, leading to regulation of collagen secretion to mediate body size regulation in C. elegans.
Phosphorylation of the phosphatase SHP-1 by PKC-θ in natural killer (NK) cells induces SHP-1 inhibition, revealing a novel molecular pathway that sustains NK cell activation threshold.
Sensory activity within the superior colliculus is read out by downstream motor structures and contributes to individual saccade kinematics with single spike precision.
Slow, continuous changes in eye position when gaze is fixed, previously believed to be random drifts, are shown to exhibit highly systematic and short-latency response characteristics to visual stimuli.

A simple way to create larger volumes of fat tissue for food purposes may be to grow individual fat cells and mechanically combine them together (rather than directly growing the full tissue).

Electron paramagnetic resonance spectroscopy quantitatively correlates structural damages of serum albumin with COVID-19 severity and mortality thus suggesting albumin replacement therapy as a strategy to rescue patients at risk of mortality.
