Advances in animal magnetoreception have been limited by a lack of tractable vertebrate laboratory models. Here, the authors demonstrate light-independent magnetoreception in mature zebrafish and medaka, as well as magnetosensitive locomotion in juvenile

Multi-modal imaging and analysis in the search for iron-based magnetoreceptors in the honeybee Apis mellifera [PDF]
The honeybee Apis mellifera is one of many animal species for which empirical evidence of a magnetic sense has been provided. The underlying mechanisms postulated for magnetoreception in bees are varied, but most point towards the abdomen as the most ...

Approaching the Quantum Limit of Energy Resolution in Animal Magnetoreception [PDF]
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.

Role of chiral-induced spin selectivity in the radical pair mechanism of avian magnetoreception. [PDF]
In this paper, we investigate the effect of chiral-induced spin selectivity (CISS) on the radical pair mechanism of avian magnetoreception. We examine the impact of spin selectivity on the avian compass sensitivity. In this analysis, we also consider the

Magnetoreception in birds [PDF]
Birds can use two kinds of information from the geomagnetic field for navigation: the direction of the field lines as a compass and probably magnetic intensity as a component of the navigational ‘map’. The direction of the magnetic field appears to be sensed via radical pair processes in the eyes, with the crucial radical pairs formed by cryptochrome ...

The avian magnetic compass allows orientation during migration and is shown to function properly under short-wavelength but not long-wavelength visible light.

Mitohormesis is a process whereby mitochondrial stress responses, mediated by reactive oxygen species (ROS), act cumulatively to either instill survival adaptations (low ROS levels) or to produce cell damage (high ROS levels).

Virtual magnetic displacements are used to examine the magnetoreceptive ability of animals by changing the local magnetic field to emulate one that exists elsewhere. This technique can be used to test whether animals use a magnetic map.

The Magnetic Compass of Birds: The Role of Cryptochrome
The geomagnetic field provides directional information for birds. The avian magnetic compass is an inclination compass that uses not the polarity of the magnetic field but the axial course of the field lines and their inclination in space.

To navigate between breeding and wintering grounds, night-migratory songbirds are aided by a light-dependent magnetic compass sense and maybe also by polarized light vision.
