Space is radioactive. And this could put a hold on deep-space missions. 🌏 engineering
Near Earth, unconscionable levels of ionizing radiation swarm around our tenuous atmosphere, protected only by our magnetosphere. It comes largely from galactic cosmic radiation, fueled by the seemingly endless activity of the Milky Way.
However, scientists haven't had bountiful opportunities to grasp this problem, mainly because of safety and technical issues. But the can provide a model to safely and accurately generate double-strand breaks in eukaryotes, the kind of cells humans use. The study's findings are the first-ever expansion of scientists' molecular biology"toolkit" aboard the International Space Station.Beyond the protective shield of the Earth's magnetosphere, ionizing radiation places any present astronauts at risk of extensive DNA damage.
, causing clustered and complex DNA damage that is not easy to repair. This means knowing which of the two repair pathways mentioned above is optimal is crucial to mitigate damage in astronauts exposed to space radiation.Earlier studies have shown that the DNA repair mechanism pathway may be influenced in conditions under a measure of microgravity.
