Evolutionary constraints permeate large metabolic networks

Abstract Background Metabolic networks show great evolutionary plasticity, because they can differ substantially even among closely related prokaryotes.Any one metabolic network can also effectively compensate for the blockage of individual reactions by rerouting metabolic flux through other pathways.These observations, together with the continual

Viscoelastic circular cell honeycomb helmet liners for reducing head rotation and brain strain in oblique impacts

Rotational head motion is one of the major contributors to brain tissue strain during head impacts, which damages axons and vessels Medium Weight and leads to traumatic brain injury.Helmet technologies have come to market promising enhanced protection against such rotational head motion.We recently introduced novel air-filled viscoelastic cell arra
