Reported in April 2019 local time, NASA astronaut Shikaote waited for 340 days in international space station, is the scientist very curious whether does his body state have occurrence change? Search to undertake comparing is opposite with the twin brother mark with his same gene then, the result discovers Shikaote " immune system and DNA rehabilitate function " occurrence mutation, from the point of the angle of genetic gene, it is the permanent loss that cannot recover. (the picture comes from IC Photo)According to " science " the research report of periodical, after Shikaote of 55 years old returns the earth 3 years, the scientist spreads out systemic examination to him, discover he is waited for in aerospace this paragraph during carotid become light with retinal thickening, weight, alvine path is microbial grow in quantity, and cognitive ability drops, nevertheless, these symptoms are in mostly return the earth disappear gradually after 6 months, only alone the change of the 8.7 ％ in gene still did not restore up to now. (the picture comes from IC Photo)Shikaote expresses, a few days that when just returned the earth are very afflictive, have very long period of time quite tired out without vigor, "I still think I got flu " . (the picture comes from IC Photo)Saidele says scientist of nerve of Florida university acknowledge, "These gene mutation won't create immediate risk to astronaut, but do not eliminate to be able to increase them to did not suffer from cancered risk. " (the picture comes from IC Photo)The Li of cancer biologist shellfish that division collect pulls much city to establish an university expresses, human chromosome extreme has cry " upright bead " part, as the age normally growth can shorten gradually, radiation, pollution, pressure waits an element a moment to bring about it likely to shorten quickly, what Dan Ji blames is, shikaote goes after aerospace, upright bead did not shorten actually, before be being compared instead longer, exchange a word for namely " his cell is younger than before " , it is likely very " aerospace wakes up him inside body cell of some part sleep deeply " . (the picture comes from IC Photo)Nevertheless, researcher points out, gene generation mutation has Shikaote 5 kinds likelihood, include the impact that manage of opposite of aerospace radiate, 0 gravitational environments brings among them. (the picture comes from IC Photo)The outer space that needs at the outset because of Shikaote stands, as it happens is in radiate of Fan Ailun of high-energy and electrified particle to take lower part, radiation measures 48 times be the earth, soma will be so busy all the time repair radiation is harmed, just can appear this kind is choppy.
