title: The Fading Electricity Theory of Ageing: the missing biophysical principle?
abstract: Since a few years convincing data are accumulating showing that some of the premises of the master integrative theory of ageing, namely Harman's Reactive Oxygen Species or free radical theory, are less well founded than originally assumed. In addition, none of the about another dozen documented ageing mechanisms seems to hold the final answer as to the ultimate cause and evolutionary significance of ageing. This review raises the question whether, perhaps, something important has been overlooked, namely a biophysical principle, electrical in nature. The first cell on earth started to be alive when its system for generating its own electricity, carried by inorganic ions, became operational. Any cell dies at the very moment that this system irreversibly collapses. In between birth and death, the system is subject to wear and tear because any cell's overall repair system is not 100 percent waterproof; otherwise adaptation would not be an option. The Fading Electricity Theory of Ageing has all necessary properties for acting as a universal major integrative concept. The advent of novel methods will facilitate the study of bioelectrical phenomena with molecular biological methods in combination with optogenetics, thereby offering challenging possibilities for innovative research in evo-gero.
