A New Paradigm for Understanding the Rheology and Processability of Poly(p‐Phenylene Terephthalamide) Liquid‐Crystalline Solutions

Journal of Applied Polymer Science, EarlyView.
Kevlar is traditionally modeled as a rigid‐rod polymer, yet rheological behavior deviates from this assumption. The review introduces a novel “twist‐tie” entanglement theory for aramid polymer chains in the nematic liquid crystal state, providing a molecular explanation for deviations from rigid‐rod models. Understanding twist‐tie entanglement dynamics

Finite element analysis of feeding in red and gray squirrels (Sciurus vulgaris and Sciurus carolinensis)

The Anatomical Record, EarlyView.
Abstract Invasive gray squirrels (Sciurus carolinensis) have replaced the native red squirrel (Sciurus vulgaris) across much of Great Britain over the last century. Several factors have been proposed to underlie this replacement, but here we investigated the potential for dietary competition in which gray squirrels have better feeding performance than ...

Born this way: Does variation in perinatal limb bone morphology predict adult locomotor repertoire in primates?

The Anatomical Record, EarlyView.
Abstract Primates show a high degree of locomotor diversity that engenders similar variance in limb bone cross‐sectional geometry and bending strength: leaping primates have stronger hindlimb bones whereas suspensory species have stronger forelimb bones.

Drivers of tail evolution in squamates and their implications for the fossorial origin of snakes

The Anatomical Record, EarlyView.
Abstract The axial skeleton serves as the primary structural support in all vertebrates and is subdivided into five distinct regions: cervical, thoracic, lumbar, sacral, and caudal. Relaxation of constraints acting on the terminal end of the axial skeleton has led to remarkable variation in caudal vertebrae number across Squamata.

Sheep Horn Development Revealed by Multi‐Tissue and Cross‐Species Transcriptomic Analysis

Animal Research and One Health, EarlyView.
Multi‐tissue and cross‐species transcriptomics with allele‐specific expression show sheep horns are a composite organ integrating epidermal and osteogenic programs. Conserved horn gene modules and cis‐regulatory variation fine‐tune expression networks underlying horn development and size (small scurs vs. large spiral horns).

The quality of interaction with children in collective play: Children's agency

British Educational Research Journal, EarlyView.
Abstract There is a growing body of studies on increasing the quality of infant–toddler education and care. Yet little attention has been directed towards how to bring toddlers' agency and perspective to their personally meaningful learning in collective play.
