A team of scientists from Russia and Canada has analyzed the effect of space conditions on the protein composition in blood samples of 18 Russian cosmonauts. The results indicate many significant changes in the human body are caused by space flight. These changes are intended to help the body adapt and take place in all major types of human cells, tissues and organs. The results of the research have been published in the prestigious scientific journal Scientific Reports. Skoltech and MIPT Professor Evgeny Nikolaev led the study and is a corresponding author.
