Transcriptional Homeostasis of Oxidative Stress-Related Pathways in Altered Gravity [PDF]
, 2018 Whereby several types of cultured cells are sensitive to gravity, the immune system belongs to the most affected systems during spaceflight. Since reactive oxygen species/reactive nitrogen species (ROS/RNS) are serving as signals of cellular homeostasis,

The Influence of Altered-Gravity on Bimanual Coordination: Retention and Transfer
Frontiers in Physiology, 2022 Many of the activities associated with spaceflight require individuals to coordinate actions between the limbs (e.g., controlling a rover, landing a spacecraft).

Challenges to the Vestibular System in Space: How the Brain Responds and Adapts to Microgravity
Frontiers in Neural Circuits, 2021 In the next century, flying civilians to space or humans to Mars will no longer be a subject of science fiction. The altered gravitational environment experienced during space flight, as well as that experienced following landing, results in impaired ...

Interaction Network Provides Clues on the Role of BCAR1 in Cellular Response to Changes in Gravity
Computation, 2021 When culturing cells in space or under altered gravity conditions on Earth to investigate the impact of gravity, their adhesion and organoid formation capabilities change. In search of a target where the alteration of gravity force could have this impact,

The Sensitivity of an Immature Vestibular System to Altered Gravity
Journal of Experimental Zoology Part A: Ecological Genetics and Physiology, 2012 ABSTRACTStimulus deprivation or stimulus augmentation can induce long‐lasting modifications to sensory and motor systems. If deprivation is effective only during a limited period of life this phase is called “critical period.” A critical period was described for the development of the roll‐induced vestibuloocular reflex (rVOR) of Xenopus laevis using ...

, 2023 The four basic fundamental physical forces that exist in nature are: weak nuclear force, strong nuclear force, electromagnetic force, and gravity. Out of all these forces, gravity is the weakest. It is a force that is always present. It pulls objects toward each other. It helped shape the universe. It also affects life on Earth.
