Theoretical model of interstitial diffusion in solid solution under hypergravity conditions

AIP Advances
Diffusion of atoms and molecules is usually driven by concentration gradients, with the influence of gravitational energy being negligible. However, for alloying components operating at exceptional rotational speeds, such as engine blades, the resulting ...

Hypergravity as a Tool for Cell Stimulation: : Implications in Biomedicine

Frontiers in Astronomy and Space Sciences, 2016
Gravity deeply influences numerous biological events in living organisms. Variations in gravity values induce adaptive reactions that have been shown to play important roles, for instance in cell survival, growth, and spatial organization. In this paper,

Hypergravity Increases Blood–Brain Barrier Permeability to Fluorescent Dextran and Antisense Oligonucleotide in Mice

Cells, 2023
The earliest effect of spaceflight is an alteration in vestibular function due to microgravity. Hypergravity exposure induced by centrifugation is also able to provoke motion sickness.

Integration of the arts and biomedical engineering in innovative interdisciplinary anatomy education: The synthetic anatomy module

Anatomical Sciences Education, Volume 19, Issue 9, Page 1533-1545, September 2026.
Abstract The intersection of science and art has historically fostered innovation, yet the integration of creative arts into anatomy education remains limited. The Synthetic Anatomy module was designed to bridge anatomy teaching with creative design for bioscience and biomedical engineering students. This study evaluates the module's educational impact

Women in space: A review of known physiological adaptations and health perspectives

Experimental Physiology, Volume 111, Issue 9, Page 3944-3967, 1 September 2026.
Abstract Exposure to the spaceflight environment causes adaptations in most human physiological systems, many of which are thought to affect women differently from men. Since only 11.5% of astronauts worldwide have been female, these issues are largely understudied.

MCA1 and MCA2 Are Involved in the Response to Hypergravity in Arabidopsis Hypocotyls

Plants, 2020
Plants respond to and resist gravitational acceleration, but the mechanism of signal perception in the response is unknown. We studied the role of MCA (mid1-complementing activity) proteins in gravity perception by analyzing the expression of the MCA1 ...

50% body weight loading reduces stature increases and lumbar disc expansion from 4 h hyper‐buoyancy floatation versus 15 min sitting upright

Experimental Physiology, Volume 111, Issue 9, Page 4126-4139, 1 September 2026.
Abstract Microgravity is associated with stature increases, back pain and post‐flight intervertebral disc (IVD) herniation. This study aims to determine whether 30 s seated 50% body weight (BW) axial loading is comparable to 15 min sitting upright in 1 g upon changes in stature, anterior lumbar IVD height (via ultrasound), passive vertebral stiffness ...

An experimentally informed computational model of neurovestibular adaptation to altered gravity

Experimental Physiology, Volume 111, Issue 9, Page 4195-4208, 1 September 2026.
Abstract Transitions to altered gravity environments result in acute sensorimotor impairment for astronauts, leading to serious mission and safety risks in the crucial first moments in a new setting. Our understanding of the time course and severity of impairment in the early stages of adaptation remains limited and confounded by unmonitored head ...

Hyper‐buoyancy flotation increases cervical disc height and reduces vertebral stiffness, with only partial reversal after acute 1 g axial loading

Experimental Physiology, Volume 111, Issue 9, Page 4166-4178, 1 September 2026.
Abstract Exposure to microgravity is associated with stature increases, moderate‐to‐severe back/neck pain and elevated lumbar and cervical intervertebral disc (IVD) herniation risk post‐flight. Whilst lumbar pathophysiology has been investigated, little attention has been placed on the cervical spine.
