Boundary:boundary pairing generates either stem-loop or circle-loop TADs, and these loop topologies differ in how they impact chromosome structure and genetic activities.

Fruit fly chromosomes are divided into discrete structural domains by regions of decompacted chromatin, suggesting a novel model for the formation of a known class of genetic elements.
Cranial endocasts of fossil and extant lungfish, analysed via tomography and novel principle component analyses designed for use with missing data, show that lungfish forebrain and inner ear regions show the most variation in brain shape evolution through time.
A novel mechanism of gene regulation is discovered wherein a specific long non-coding RNA abolishes the blocking activity of chromatin insulator in the Drosophila HOX gene cluster.

Combining micropatterning, traction force microscopy, and optogenetics, it is shown that epithelial cells actively respond to mechanical signals from neighboring cells.
The molecular identity of bi-fated tendon-to-bone attachment cells, which display a mixture of transcriptomes of two neighboring cell types, enables the formation of the unique transitional tissue of the enthesis.
