Those interested in issues of communication at the nanoscale will be interested to learn that the first volume of the new journal Nano Communication Networks, from Elsevier, edited by Ian Akyildiz, is available free of charge. The volume comprises four issues dated March through December of 2010. Just to pick one article out of dozens available, I found “A brief review of molecular information theory” by Thomas D. Schneider useful. His analysis, in terms of Claude Shannon’s information theory, of the control of gene expression by proteins binding to specific sites on DNA leads him to conclude that “we should be able to build molecular communications that are just as robust as our macroscopic ones.”
