Study suggests marine cyanobacteria communicate via membrane nanotubes

Three years ago, María del Carmen Muñoz, a researcher at the University of Cordoba, was peering into an electron microscope to study the vesicles of marine cyanobacteria and found, almost accidentally, something she did not expect: structures that, although they had already been discovered years ago in other bacteria, had never been found in this type of living being, responsible for producing more than half of the oxygen on Earth.
