Medical scientists have underlined that cosmic radiation has the capacity to harm the brains of astronauts in deep space by accelerating the development of Alzheimer's disease. Basically, the scientists have discovered that a specific kind of space radiation known as highmass, high-charged particles highly threatened the health of astronauts. In fact, these cosmic radiations are the outcome of exploding stars which move in space at very high speeds and while punching through solid objects such as a spacecraft. Besides, the galactic cosmic radiation consists of iron particles. In-depth research have revealed that it is the first time that exposure to radiation levels have proved to produce cognitive problems and speed up changes in the brain! The study team wanted to see if radiation had the potential to accelerate Alzheimer's in those who were genetically vulnerable...
