Magnetoreception in Microorganisms [PDF]
Magnetoreception is the sense whereby organisms geolocate and navigate in response to the Earth's magnetic field lines. For decades, magnetotactic bacteria have been the only known magnetoreceptive microorganisms. The magnetotactic behaviour of these aquatic prokaryotes is due to the biomineralization of magnetic crystals.

C. elegans is not a robust model organism for the magnetic sense
Attempts to replicate studies proposing a magnetoreceptive capacity of C. elegans were unsuccessful, suggesting it is not a suitable organism for the study of the magnetic sense.

Biological Effects of Space Hypomagnetic Environment on Circadian Rhythm
The intrinsic earth magnetic field (geomagnetic field, GMF) provides an essential environmental condition for most living organisms to adapt the solar cycle by rhythmically synchronizing physiological and behavioral processes. However, hypomagnetic field

Biological effects of the hypomagnetic field: An analytical review of experiments and theories. [PDF]
During interplanetary flights in the near future, a human organism will be exposed to prolonged periods of a hypomagnetic field that is 10,000 times weaker than that of Earth's.

: Cryptochromes are blue-, or ultraviolet-, light-absorbing proteins involved in the circadian clock, blue/ultraviolet light perception and potentially magnetoreception. At least 4 separate cryptochrome genes have been identified in avian species.

An assay to investigate factors influencing initial orientation in nocturnally fledging seabirds
The first solitary migration of juvenile birds is difficult to study because of a low juvenile survival rates and sometimes long delays in return to the breeding grounds.

Direct Interaction of Avian Cryptochrome 4 with a Cone Specific G-Protein
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 ...

Magnetic alignment enhances homing efficiency of hunting dogs
Despite anecdotal reports of the astonishing homing abilities in dogs, their homing strategies are not fully understood. We equipped 27 hunting dogs with GPS collars and action cams, let them freely roam in forested areas, and analyzed components of ...

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 ...

In night-migratory songbirds, neurobiological and behavioral evidence suggest the existence of a magnetic sense associated with the ophthalmic branch of the trigeminal nerve (V1), possibly providing magnetic positional information. Curiously, neither the
