Query: On the physical basis of biological signaling by interface pulses   Currently, biological signaling is envisaged as a combination of activation
and movement, triggered by local molecular interactions and molecular
diffusion, respectively. However, we here suggest, that other fundamental
physical mechanisms might play an at least equally important role. We have
recently shown that lipid interfaces permit the excitation and propagation of
sound pulses. Here we demonstrate that these reversible perturbations can
control the activity of membrane-embedded enzymes without a requirement for
molecular transport. They can thus facilitate rapid communication between
distant biological entities at the speed of sound, which is here of the order
of 1 m/s within the membrane. The mechanism described provides a new physical
framework for biological signaling that is fundamentally different from the
molecular approach that currently dominates the textbooks.
