A large number of magnetic sensors, like superconducting quantum interference devices, optical pumping, and nitrogen vacancy magnetometers, were shown to satisfy the energy resolution limit. This limit states that sensitivity sensor, when translated into a product with time, is bounded below by Planck's constant, ℏ. bound implies fundamental limitation as what can be achieved in sensing. Here we explore biological particular three magnetoreception mechanisms thought underly animals' geomagnetic field sensing: radical-pair, magnetite, MagR mechanism. We address question how close these approach At quantitative level, utility it informs workings sensing model-independent ways thus provide subtle consistency checks for theoretical models estimated or measured parameter values, particularly needed complex systems. qualitative closer ℏ, more “quantum” sensor. offers an alternative route towards understanding biology magnetoreception. It also quantifies room improvement, illuminating nature has achieved, stimulating engineering biomimetic sensors exceeding nature's performance. Published American Physical Society 2025

Electromagnetic fields regulate iron metabolism: From mechanisms to applications

Journal of Advanced Research, Journal Year: 2025, Volume and Issue: unknown

Published: April 1, 2025

Electromagnetic fields (EMFs), as a form of physical therapy, have been widely applied in biomedicine. Iron, the most abundant trace metal living organisms, plays critical role various physiological processes, and imbalances its metabolism are closely associated with development progression numerous diseases. Numerous studies demonstrated that EMF exposureinduces significant changes both systemic cellular iron metabolism. This review aims to summarize evidence potential biophysical mechanisms underlying EMFs regulating metabolism, thereby enhancing understanding their biological expanding applications biomedical fields. In this review, we synthesized research findings proposed hypothesis regulate involve special electromagnetic properties iron-containing proteins iron-enriched tissues, well modulation membrane structure function, ion channels, generation activity Reactive Oxygen Species (ROS). Then, summarizes latest advances effects on safety, impact immunoregulation, cardiovascular diseases, neurological orthopedic diabetes, liver injury, cancer.
