Scientists discover the molecular switch for nerve cells' insulating jelly rolls
...f myelin, producing the biological equivalent of a jelly roll. Using a sophisticated system for growing nerve cells in laboratory dishes, the team identified a gene called neuregulin as the myelin signal. This signal directs Schwann cells, the nervous system's cellular architects, to build elaborate sheat...A new look at the state of the oceans
