A new study of the ISS will help create a medicine for the treatment of muscles and bones

Being a long time in zero gravity,cosmonauts cause great harm to their health. In particular, their muscles and bones become very weak, and at the moment they can only reduce damage by regular exercise, and then undergo a lengthy recovery process on Earth. It seems that rehabilitation will speed up soon - the ISS crew will conduct an experiment, the results of which will help to create a medicine for treating the effects of being in zero gravity.

Scientists know that the greatest harm to the bodycosmonauts are applied by oxidative processes occurring in their organisms. Under the conditions of the International Space Station, they want to find out how weightlessness affects the production of reactive oxygen species that can damage DNA and protein molecules. Based on the results obtained, antioxidants will be developed to prevent oxidation.

According to the press release of the European SpaceAgency ESA, materials for the new study were delivered to the ISS inside the cargo capsule SpaceX Dragon. During the experiment, the station crew will take samples of living cells and add ceramic nanoparticles, called nanoceriums, to them. They will be kept at a 30-degree temperature for six days - it is expected that the added components will protect cells from the effects of oxidative processes.

It is noteworthy that the cells will be divided into twoGroups: one will be in conditions of weightlessness, and the other - to be exposed to artificial gravity inside the centrifuge. The control group of cells with ceramic nanoparticles will be on Earth - by comparing all groups, scientists will find out the effectiveness of nanoparticles as antioxidants.

According to representatives of the space agency ESA, the study can give rise to the development of a method of stimulating cells not only to prevent the effects of weightlessness, but also to slow down aging.
