More biologic complexity in cell research. It seems exosomes, little globules released from cells are not just garbage collectors as first proposed. They contain RNA (!) and can affect other cells at a distance. A whole new area of research has opened up and turns out to be highly complex. I'm not surprised. I predict Life will turn out to be so complex at the current levels which we study, that we will have to conclude that original life was extremely complex also. Otherwise the road from 'now' back to 'then' could not conceivably been traveled.-http://the-scientist.com/2011/07/01/exosome-explosion/
