Other documented effects of space travel include bone and muscle atrophy, cardiovascular changes, issues with the balance system in the inner ear and a syndrome involving the eyes.

The study, funded by the Canadian Space Agency, follows NASA-funded research published on June 8 that detailed brain changes in astronauts - expansion of spaces in the brain containing fluid that cushions it to protect against sudden impact and remove waste products. It also has been shown that astronauts in space shed more viral particles in their biological fluids - saliva and urine - increasing the risk of spreading pathogens to other astronauts whose own immune systems may be weakened. This has included reactivation of latent viruses such as: Epstein-Barr, responsible for infectious mononucleosis varicella-zoster, responsible for shingles and herpes simplex 1, responsible for cold sores. 1 Their father is HIV positive their mother, the. Scientists previously documented astronauts experiencing immune dysfunction in space. The world’s first known CRISPRed babies, Chinese twin girls, were born in October 2018 after researcher He Jiankui used clustered regularly interspaced short palindromic repeat (CRISPR) technology to disable a gene called CCR5 in their genomes so as to render the babies immune to HIV. 'New and specific countermeasures will be needed,' Trudel said. It is unlikely that greater solar radiation exposure in space was the culprit, they added. This altered behavior, the researchers said, may result from a phenomenon called 'fluid shift' in which blood in the absence of Earth's gravitational pull is redistributed from the lower to the upper part of the body. Discovering altered gene behavior in leukocytes is 'a significant step toward understanding human immune dysregulation in space,' Trudel added.
