A Mechanism of Cohesin-Dependent Loop Extrusion Organizes Zygotic Genome Architecture

, 2017
SUMMARYFertilization triggers assembly of higher-order chromatin structure from a naïve genome to generate a totipotent embryo. Chromatin loops and domains are detected in mouse zygotes by single-nucleus Hi-C (snHi-C) but not bulk Hi-C.

Exuberant long noncoding RNA expression may sculpt Igh locus topology

Frontiers in Immunology
Diverse Igh repertoires require successful V(D)J recombination allowing B cell receptor expression and Ig secretion for humoral immune responses. Igh locus contraction has been implicated in generating spatial proximity between distal VH segments and the

Liquid Crystalline Elastomers in Soft Robotics: Assessing Promise and Limitations

Advanced Robotics Research, EarlyView.
Liquid crystalline elastomers (LCEs) are programmable soft materials that undergo large, anisotropic deformation in response to external stimuli. Their molecular alignment encodes directional actuation in a monolithic structure, making them long‐standing candidates for soft robotic systems.

A Soft Robotic Device for Targeted Massage Therapy of Residual Limbs

Advanced Robotics Research, EarlyView.
Residual limb edema after amputation can hinder recovery and delay prosthetic fitting. This study presents a soft‐robotic wearable device that delivers sequential compression through pneumatic McKibben actuators. By replicating the principles of manual lymphatic drainage, the device generates controlled mechanotherapeutic pressure patterns, providing a
