Several interacting molecular and biochemical processes are vital to establishing cell polarity. In a recent study, researchers at the Indian Institute of Science, Bengaluru, studied some of these signals in the centrosome—an organelle in the cell responsible for cellular organisation—of a single-cell embryo.
A unique material, chromium antimonide (CrSb), defies conventional rules by conducting electricity like two different materials in one, dominated by electrons in one direction and holes in another, a phenomenon called DDCP.
