Purification of two conserved protein complexes, the γ-TuRC and Augmin, using a simple affinity technique, demonstrates that they are necessary and sufficient for the essential phenomenon of branching microtubule nucleation.
Three-dimensional imaging was used to identify structural and quantitative features of developing lymphatics in the kidneys of mice, humans and in a genetic mouse model of polycystic kidney disease.

The complete elimination of a transient superficial population of neurons, and associated immature circuits, is required for the emergence of functional properties in the mature cerebral cortex.
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.
The first successful de novo design of a homo-trimeric protein that binds a C3 symmetric small molecule larger than a metal ion is an advance for computational protein design.

Jumping of transposable elements provides DNA-binding sites for the MADS-box transcription factor PHERES1, allowing the regulation of imprinted genes and other key endosperm development genes.
By performing 15N pulse-labeling of mice, the turnover of hundreds of proteins in eye tissues was measured by mass spectrometry that revealed long-lived metabolic enzymes in the lens.

Optogenetically induced motor disruption can evoke plasticity in the mouse frontal cortex that compensates for the motor deficits, accompanying changes in inter-hemispheric motor representation.

Sperm production and male fertility in Drosophila melanogaster depend on transcripts generated from the AAGAG(n) repeated satellite DNA within primary spermatocytes.
