本文探讨人类多行星定居背景下,磁场等环境因素对生物系统的长期影响,提出自由基对机制作为弱磁场作用的可能量子生物学解释,并综述其研究进展。

摘要:

人类历史上首次有可能开始将自己想象为多行星物种。这一目标将需要在多个领域进行技术创新,包括医疗保健领域。地球上所有生命都共享着与特定环境条件(包括引力场和磁场)耦合的演化过程。虽然人体或许能够适应太空飞行期间这些场的短期干扰,但任何长期定居都必须考虑不同场对生物系统的影响,这种影响不仅限于个体一生,还会跨越世代。例如,磁场影响再生过程中干细胞的生长。昼夜节律深受磁场影响,这一事实可能对心理和身体健康都会产生影响。甚至大脑也会对这一场的微小扰动做出反应。弱磁场对生物系统影响的一种可能机制被认为是自由基对机制。自由基对机制起源于自旋化学领域,用于描述磁场如何影响化学反应的产率。该机制随后被纳入量子生物学领域。量子生物学,最广义地说,是研究非平凡的量子效应是否在生物系统中发挥任何有意义的作用。自由基对机制在此背景下最常被用于描述鸟类指南针。然而,最近许多研究调查了自由基对可能发挥作用的其他生物情境,从麻醉剂和抗抑郁药的作用,到微管发育和昼夜节律钟的正常功能……(完整摘要见手稿)

英文摘要:

For the first time in history, humankind might conceivably begin to imagine itself as a multi-planetary species. This goal will entail technical innovation in a number of contexts, including that of healthcare. All life on Earth shares an evolution that is coupled to specific environmental conditions, including gravitational and magnetic fields. While the human body may be able to adjust to short term disruption of these fields during space flights, any long term settlement would have to take into consideration the effects that different fields will have on biological systems, within the space of one lifetime, but also across generations. Magnetic fields, for example, influence the growth of stem cells in regenerative processes. Circadian rhythms are profoundly influenced by magnetic fields, a fact that will likely have an effect on mental as well as physical health. Even the brain responds to small perturbations of this field. One possible mechanism for the effects of weak magnetic fields on biological systems has been suggested to be the radical pair mechanism. The radical pair mechanism originated in the context of spin chemistry to describe how magnetic fields influence the yields of chemical reactions. This mechanism was subsequently incorporated into the field of quantum biology. Quantum biology, most generally, is the study of whether non-trivial quantum effects play any meaningful role in biological systems. The radical pair mechanism has been used most consistently in this context to describe the avian compass. Recently, however, a number of studies have investigated other biological contexts in which the radical pair might play a role, from the action of anaesthetics and antidepressants, to microtubule development and the proper function of the circadian clock...
