This theoretical biophysics study models the radical pair mechanism as an open quantum system to derive an explicit dependence of magnetic-field effects on the spin coherence relaxation time (τ) and chemical kinetics (k). It reports a condition under which RPM effects become significant and estimates τ in cryptochrome-like proteins to be on the order of units to tens of nanoseconds. The paper also reports that nanoTesla-level radio-frequency fields have minor influence and are unlikely to disrupt RPM patterns under the modeled decoherence.

This 2025 review examines claims of biological effects from weak, nonthermal RF magnetic fields and evaluates whether such effects could be mediated by the radical pair mechanism (RPM). It reports that aligning RPM theory with low-level experimental observations remains difficult and that many experimental findings are limited by reproducibility, statistical robustness, and dosimetry issues. The authors conclude a tangible but incompletely understood link may exist and emphasize the need for more rigorous, standardized, interdisciplinary work.

This article is a commentary on how emotions and community dynamics can bias scientific reasoning when a favored hypothesis becomes a "ruling hypothesis." Using animal magnetoreception as an example, it argues that radical-pair/cryptochrome-centered frameworks may sometimes be treated as dominant, potentially leading to selective interpretation of evidence. The authors call for separating individual intent from community-wide bias and offer recommendations to mitigate these risks.

This in vitro study reports that a static magnetic field (SMF) combined with paramagnetic calcium-polypyrrole nanoparticles (Ca-PPy) markedly increases bactericidal activity against E. coli and S. aureus. The authors attribute the enhanced killing to increased reactive oxygen species generation and associated membrane disruption, with computational analysis suggesting altered radical-pair transitions under magnetic fields. The abstract frames SMF as potentially biocompatible and useful for bactericidal applications, while also noting broader biological impacts of electromagnetic fields.

This mini-review discusses the radical pair mechanism as a plausible biophysical route by which external magnetic fields could influence biochemical processes in living systems. It is intended as a primer for magneto-oncology researchers to assess whether observed magnetic-field-related biomedical effects may be explained by radical pair biochemistry. The article also notes the value of this framework for refining therapeutic protocols and for identifying potential experimental artifacts in oncology-related magnetic field research.
