Cyanobacteria use an AM radio-like mechanism to regulate their genes, with the cell division cycle acting as a “carrier wave” and their circadian clock modulating the pulse strength to integrate signals from these two rhythms. This discovery explains how cells coordinate these oscillatory processes and may have applications in biotechnology and synthetic biology. Credit: SciTechDaily.com Cyanobacteria use an AM radio-like principle to coordinate cell division with circadian rhythms, encoding information through pulse amplitude modulation. Cyanobacteria, an ancient group of photosynthetic bacteria, have been discovered to regulate their genes using the same physics principle used in AM radio transmission. New research...
