Drosophila melanogaster Sperm under Simulated Microgravity and a Hypomagnetic Field: Motility and Cell Respiration. [PDF]

Int J Mol Sci, 2020
The role of the Earth’s gravitational and magnetic fields in the evolution and maintenance of normal processes of various animal species remains unclear. The aim of this work was to determine the effect of simulated microgravity and hypomagnetic conditions for 1, 3, and 6 h on the sperm motility of the fruit fly Drosophila melanogaster.

A Current Overview of the Biological Effects of Combined Space Environmental Factors in Mammals [PDF]

Frontiers in Cell and Developmental Biology, 2022
Distinct from Earth’s environment, space environmental factors mainly include space radiation, microgravity, hypomagnetic field, and disrupted light/dark cycles that cause physiological changes in astronauts. Numerous studies have demonstrated that space

Biological Effects of Space Hypomagnetic Environment on Circadian Rhythm [PDF]

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

The radical pair mechanism of biological effects on hypomagnetic fields and one method to verify it [PDF]

Journal of Life Sciences Research, 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 ...

Renaissance for magnetotactic bacteria in astrobiology. [PDF]

ISME J, 2023
Capable of forming magnetofossils similar to some magnetite nanocrystals observed in the Martian meteorite ALH84001, magnetotactic bacteria (MTB) once occupied a special position in the field of astrobiology during the 1990s and 2000s.

Hypomagnetic field effects as a potential avenue for testing the radical pair mechanism in biology

Frontiers in Physics, 2023
Near-zero magnetic fields, called hypomagnetic fields, are known to impact biological phenomena, including developmental processes, the circadian system, neuronal and brain activities, DNA methylation, calcium balance in cells, and many more.

Effects of hypomagnetic field on adult hippocampal neurogenic niche and neurogenesis in mice

Frontiers in Physics, 2022
The elimination of geomagnetic field (GMF), also called hypomagnetic field (HMF), is one of the major environmental hazards faced by deep-space astronauts and the workers in magnetically shielded rooms on Earth.

Planarian regeneration in space: Persistent anatomical, behavioral, and bacteriological changes induced by space travel [PDF]

Regeneration, Volume 4, Issue 2, Page 85-102, April 2017., 2017
Regeneration is regulated not only by chemical signals but also by physical processes, such as bioelectric gradients. How these may change in the absence of the normal gravitational and geomagnetic fields is largely unknown.

The effects of different durations of exposure to hypomagnetic field on the number of active mitochondria and ROS levels in the mouse hippocampus [PDF]

Biochemistry and Biophysics Reports
Reactive oxygen species (ROS) are one of the potential molecules in response to a hypomagnetic field (HMF), and exposure to an HMF for eight weeks led to an increase in ROS levels in the whole hippocampus area in mice.
