In this study we show a reproduction of the Zhadin experiment, which consists of the transient increase of the electrolytic current flow across an aqueous solution of L-arginine and L-glutamic acid induced by a proper low frequency alternating magnetic field superimposed to a static magnetic field of higher strength. We have identified the mechanisms that were at the origin of the so-far poor reproducibility of the above effect: the state of polarization of the electrode turned out to be a key parameter. The electrochemical investigation of the system shows that the observed phenomenon involves the transitory activation of the anode due to ion cyclotron frequency effect, followed again by anode passivation due to the adsorption of amino acid and its oxidation products. The likely occurrence of similar ion cyclotron resonance (ICR) phenomena at biological membranes, the implications on ion circulation in living matter, and the consequent biological impact of environmental magnetic fields are eventually discussed.

Background: isosbestic (equal absorption) points in the IR and NIR spectra of liquid water are a well-known feature and they witness the existence of two populations of oscillators in the probed system. Despite it is a well-known experimental fact, in the mainstream molecular dynamics approach the proposed theoretical explanations for it are not able to elucidate which is the physical reason why such a "cut-off frequency" (at the isosbestic point) does exist. Methods: We investigate pure Milli-Q water on increasing the temperature in the vis-NIR range (400-2500 nm). We specifically payed attention to the first overtone region (1300-1600 nm) of the OH-bond stretching-mode where an isosbestic point has been observed. Results: A second derivative analysis clearly shows two modes, which can be assigned to water molecules involved in different "hydrogen bonding" configurations whose relative abundance is controlled by the temperature. We have also observed that the ratio of these modes follows a van't Hoff behavior supporting that their energy difference (energy gap) is independent on the temperature. Furthermore, a log-log plot shows a scale invariance of the population ratio with respect to the perturbation (temperature), confirming the existence of a long-range correlated dynamics in the liquid. Conclusions: We show that the two phases differences between energy and entropy estimated from the experimental data can be compared with the prediction of Quantum Electro Dynamics (QED) showing a remarkable agreement.

Oxhydroelectric Effect, that is the extraction of electricity from an aqueous electrolytic solution by twin Platinum (Pt) electrodes, mediated by oxygen molecules, has been detected for the first time in bi-distilled water (electric conductivity of 1.2 microSiemens/cm). A dc power of the order of tenths of microW, lasting for many hours, was measured through a resistor (47 kOhm) connected to twin Pt electrodes immersed into bi-distilled water, after the addition of some pieces of Nafion® in one semi-cell and of a very small amount of hydrogen peroxide (H2O2) - as a source of oxygen - in both semi-cells.
