ABSTRACT Except for relatively few polarity reversals the magnitude of the magnetic dipole moment of the earth has remained constant since life first began, allowing evolutionary processes to integrate the geomagnetic field (GMF) into several biological functions. One of these, bearing the classical signature of an ion cyclotron resonance (ICR)-like interaction, results in biological change associated with enhanced proton transport. The wide range of cation masses over which this effect is found suggest a fundamental biological dependence on the GMF, one that functions equally well for electric as well as magnetic fields. Such generalization of ICR requires two things: transparency of tissues to the GMF and suitably tuned ELF resonant magnetic or electric fields. To complement the widely reported ICR responses to applied AC magnetic fields, we hypothesize the existence of weak endogenous ICR electric field oscillations within the cell. This equivalence implies that even in the absence of applied AC magnetic fields, biological systems will exhibit intrinsic GMF-dependent ion cyclotron resonance intracellular interactions. Many ICR effects that have been reported appear as antagonist pairs suggesting that the characteristics of the GMF have not only been incorporated into the genome but also appear to function in an endocrine-like manner.

离子回旋共振：生命系统的地磁策略？

摘要 除了相对较少的极性反转外，地球磁偶极矩的大小自生命开始以来一直保持不变，这使得进化过程可以将地磁场 (GMF) 整合到多种生物功能中。其中之一，带有离子回旋共振 (ICR) 样相互作用的经典特征，导致与增强的质子传输相关的生物变化。发现这种效应的各种阳离子质量表明对 GMF 的基本生物学依赖性，一种在电场和磁场中同样发挥作用的物质。ICR 的这种概括需要两件事：组织对 GMF 的透明度和适当调谐的 ELF 共振磁场或电场。为了补充广泛报道的对施加的交流磁场的 ICR 响应，我们假设细胞内存在弱的内源性 ICR 电场振荡。这种等效性意味着即使没有施加交流磁场，生物系统也会表现出固有的 GMF 依赖性离子回旋共振细胞内相互作用。已报道的许多 ICR 效应表现为拮抗剂对，这表明 GMF 的特征不仅已整合到基因组中，而且似乎以类似内分泌的方式发挥作用。
