Quantum mechanics: A breakthrough into biological system dynamics

Superconductive and Josephson junction behaviour may be present in living cells. Positive experimental evidence is discussed. It is shown that the ''Josephson junction paradigm'' makes the connection possible between many different experimentally observed properties of living matter, allowing a further step towards a unitary framework for both physical and biological systems. Electromagnetic interaction plays a fundamental role. Superconductivity in biological systems can be demonstrated on theoretical grounds starting from a quantum microscopic approach to their dynamics. Josephson-like behaviour can be expected (and is observed) in single cells at cytokinesis or for two nearby cells. Electromagnetic interaction between cells is a well-endowed candidate for driving intercellular communication and for organizing the transport of material through gap junctions established between adjacent cells.
