Cursorial ground birds are paragons of bipedal running that span a
500-fold mass range from quail to ostrich. Here we investigate the
task-level control priorities of cursorial birds by analysing how they
negotiate single-step obstacles that create a conflict between body
stability (attenuating deviations in body motion) and consistent leg...
The role of nanotopographical extracellular matrix (ECM) cues in vascular endothelial cell (EC) organization and function is not well-understood, despite the composition of nano- to microscale fibrillar ECMs within blood vessels. Instead, the predominant modulator of EC organization and function is traditionally thought to be hemodynamic shear stress, in which...
