C. elegans is not a robust model organism for the magnetic sense

Communications Biology, 2023
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

Frontiers in Physiology, 2021
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

Magnetoreception in cryptochrome enabled by one-dimensional radical motion [PDF]

AVS Quantum Science, 2023
A popular hypothesis ascribes magnetoreception to a magnetosensitive recombination reaction of a pair of radicals in the protein cryptochrome. Many theoretical studies of this model have ignored inter-radical interactions, particularly the electron ...

Biological effects of the hypomagnetic field: An analytical review of experiments and theories. [PDF]

PLoS ONE, 2017
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.

An assay to investigate factors influencing initial orientation in nocturnally fledging seabirds

Journal of Avian Biology, 2021
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.

In Search for the Avian Trigeminal Magnetic Sensor: Distribution of Peripheral and Central Terminals of Ophthalmic Sensory Neurons in the Night-Migratory Eurasian Blackcap (Sylvia atricapilla)

Frontiers in Neuroanatomy, 2022
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

Long-term inhibition of ferritin2 synthesis in trophocytes and oenocytes by ferritin2 double-stranded RNA ingestion to investigate the mechanisms of magnetoreception in honey bees (Apis mellifera).

PLoS ONE, 2021
Behavioral studies indicate that honey bees (Apis mellifera) have a capacity for magnetoreception and superparamagnetic magnetite is suggested to be a magnetoreceptor.

Hypomagnetic Conditions and Their Biological Action (Review)

Biology, 2023
The geomagnetic field plays an important role in the existence of life on Earth. The study of the biological effects of (hypomagnetic conditions) HMC is an important task in magnetobiology. The fundamental importance is expanding and clarifying knowledge

Magnetic alignment enhances homing efficiency of hunting dogs

eLife, 2020
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 ...

Research Note: Retinal cryptochrome gene expression is not altered by presence of light in incubators

Poultry Science, 2023
: 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.
