A model of signalling pathways interacting with proneural gene expression explains the sequential patterning of the largest visual processing centre in the developing Drosophila brain.
Realistic reaction-diffusion signaling networks that include cell-autonomous factors can robustly form self-organizing spatial patterns for any combination of diffusion coefficients without requiring differential diffusivity.
The powerful computational operation of sequence recognition on behavioral timescales of approximately 1 s may emerge from synaptic activity-triggered build-up of biochemical waves in short 20 micron zones on dendrites.

A cell-sized fully confined space significantly controls the emergence and stability of a protein wave, resulting in intracellular spatiotemporal regulation driven by a reaction-diffusion mechanism.
Genetic, biochemistry and modeling approaches reveal elements of a Turing-type reaction-diffusion system to control pattern formation in differentiating cyanobacterial filaments.

A quantitative analysis of glucose-dependent transport regulation indicates that mitochondrial accumulation in regions of high nutrient availability can enhance metabolism in neuronal axons under physiologically relevant conditions.
The geometry selection rules of dynamic Min protein patterns are determined in fully confined fluidic chambers, showing that both oscillations and running waves are derivatives of spiral rotations that are established as the majority pattern.
Theoretical study shows how enzymes can achieve substrate proofreading by taking advantage of existing molecular gradients in the cell while not being endowed with structural features typically required for proofreading.
Investigations of the reaction center (RC)-light harvesting (LH) complex from an ancient chlorosome-less anoxygenic phototroph Roseiflexus castenholzii reveal the structural basis by which carotenoids assembly regulates the architecture and quinone exchange of bacterial RC-LH complex.
Theoretical analysis and in vitro reconstitution of a biological reaction-diffusion system identify key functional motifs as well as underlying principles and enable rebuilding pattern formation in a modular fashion.
