Interesting link, Howard. Thanks.
The first paragraph on the first page jumped out at
me:
Signal
transduction is the study of how cells control their own and each
others' behaviors through chemical signals. Signal transduction research is an
intensely active field of biomedical research and is of interest to a broad
array of scientists. Science's STKE should be useful to the scientists
who specialize in signal transduction, as well as the many scientists who need
to follow and apply the current findings of this field even though their primary
interest may not be in signal transduction mechanisms themselves.

Why do they assume that there are only chemical signals? Medical
science has demonstrated, for instance, that there are also electrical signals
(which is how heart cells are able to beat in unison with each other). So if
there are two modes of communication between cells, there's a good possibility
that there are more.
