Quantitative analysis in quasi-3D reveals apically driven cell behaviours that are closely coordinated across the tissue to allow ordered tube invagination through a focal point.
A continuum of genome relationships is discovered through comparative genomics of 627 sequenced mycobacteriophages isolated and characterized in an integrated research/education initiative.
Low-field single-sided magnetic resonance diffusion methods detect and measure permeability of sub-micron compartments which likely include cell processes, organelles, and cellular vesicles within ex vivo mouse spinal cords.
Optogenetic control of Cdc42 activation during polarization of budding yeast demonstrates a cell cycle regulated switch between two distinct modes of positive feedback.
Experimental evolution shows that when selection acts on two traits constrained by a trade-off, the direction of phenotypic evolution depends on the environment.
Spontaneous fusion of vesicles at synapses is regulated independently of fusion triggered by action potentials, adding to evidence that the two types of fusion have distinct functions.
A near-complete flux balance analysis model of a minimal cell demonstrates the high essentiality of its metabolic genes, agrees well with experimental essentiality data and suggests some further gene removals.
Primary-cilia-mediated processing of the Gli3 transcription factor enables the formation of subtypes of projection neurons in appropriate numbers during the development of the cerebral cortex.
