Bone marrow adiposity modulation after long duration spaceflight in astronauts

Nature Communications, 2023
Space travel requires metabolic adaptations from multiple systems. While vital to bone and blood production, human bone marrow adipose (BMA) tissue modulation in space is unknown.

The Unresolved Methodological Challenge of Detecting Neuroplastic Changes in Astronauts

Life, 2023
After completing a spaceflight, astronauts display a salient upward shift in the position of the brain within the skull, accompanied by a redistribution of cerebrospinal fluid.

Radiation Risks in a Mission to Mars for a Solar Particle Event Similar to the AD 993/4 Event

Aerospace, 2021
Within the past decade, evidence of excess atmospheric 14C production in tree rings, coupled with an increase in annually resolved measurements of 10Be in Arctic and Antarctic ice cores, have indicated that an extremely large solar particle event (SPE ...

The effect of prolonged spaceflight on cerebrospinal fluid and perivascular spaces of astronauts and cosmonauts

Proceedings of the National Academy of Sciences of the United States of America, 2022
Long-duration spaceflight induces changes to the brain and cerebrospinal fluid compartments and visual acuity problems known as spaceflight-associated neuro-ocular syndrome (SANS).

Psycho-Religious Experiences in Deep Space History: Astronaut’s Latent Countermeasures for Human Risk Management

Aerospace, 2023
Current scientific developments have reached the stage where human aspirations of space exploration are not science fiction but a reality involving travelling to the Earth’s orbit, the Moon and Mars.

Time-resolved molecular measurements reveal changes in astronauts during spaceflight

Frontiers in Physiology, 2023
From the early days of spaceflight to current missions, astronauts continue to be exposed to multiple hazards that affect human health, including low gravity, high radiation, isolation during long-duration missions, a closed environment and distance from

Sleep deficiency in spaceflight is associated with degraded neurobehavioral functions and elevated stress in astronauts on six-month missions aboard the International Space Station.

Sleep, 2022
Astronauts are required to maintain optimal neurobehavioral functioning despite chronic exposure to the stressors and challenges of spaceflight. Sleep of adequate quality and duration is fundamental to neurobehavioral functioning, however astronauts ...
