The radical pair mechanism of biological effects on hypomagnetic fields and one method to verify it
, 2023 The biological effects due to a hypomagnetic field (HMF) is a very important subject not only for aerospace traveling and space station living but also for some magnetic shielding conditions on the ground just like the underground bunkers and etc ...

Magnetic isotope effects: a potential testing ground for quantum biology
Frontiers in Physiology, 2023 One possible explanation for magnetosensing in biology, such as avian magnetoreception, is based on the spin dynamics of certain chemical reactions that involve radical pairs.

Magnetic Field Intervention Enhances Cellular Migration Rates in Biological Scaffolds
Bioengineering, 2023 The impact of magnetic fields on cellular function is diverse but can be described at least in part by the radical pair mechanism (RPM), where magnetic field intervention alters reactive oxygen species (ROS) populations and downstream cellular signaling.

Direct Interaction of Avian Cryptochrome 4 with a Cone Specific G-Protein
Cells, 2022 Background: Night-migratory birds sense the Earth’s magnetic field by an unknown molecular mechanism. Theoretical and experimental evidence support the hypothesis that the light-induced formation of a radical-pair in European robin cryptochrome 4a ...

How Important Are Radical Mechanisms in Frustrated Lewis Pair Chemistry? [PDF]
Chem, 2017 Reaction mechanism is the foundation of understanding chemical reactivity. In this issue of Chem , Stephan and co-workers overturn long-held assumptions regarding the reactivity of frustrated Lewis pairs by providing compelling evidence that radical mechanisms might operate in some cases.

Quantum measurement corrections to CIDNP in photosynthetic reaction centers
New Journal of Physics, 2013 Chemically induced dynamic nuclear polarization is a signature of spin order appearing in many photosynthetic reaction centers. Such polarization, significantly enhanced above thermal equilibrium, is known to result from the nuclear spin sorting inherent

The Innovation, 2022 How animals sense the geomagnetic field remains a mystery today. A remarkable diversity has been revealed in animal magnetoreception and several sophisticated models have been put forward in the past few decades, but none have been commonly accepted yet.

Avian magnetoreception model realized by coupling a magnetite-based mechanism with a radical-pair-based mechanism [PDF]
Chinese Physics B, 2013 Many animal species were verified to use geomagnetic field for their navigation, but the biophysical mechanism of magnetoreception has remained enigmatic. This paper presents a special biophysical model that consists of magnetite-based and radical-pair-based mechanisms for avian magnetoreception. The amplitude of the resultant magnetic field around the

Upper bound on the biological effects of 50/60 Hz magnetic fields mediated by radical pairs
eLife, 2019 Prolonged exposure to weak (~1 μT) extremely-low-frequency (ELF, 50/60 Hz) magnetic fields has been associated with an increased risk of childhood leukaemia.
