Kosmoses on astronautidega liitunud palju erinevaid olendeid. Nagu inimestelgi, on enamikul neist raske kaaluta olekuga kohaneda. \u00dcks erand on pisike uss, mida tuntakse nimega C. elegans ja kes tundub orbiidil paremini hakkama saavat kui Maal.<\/p>\n<\/div>\n

Kui ESA astronaut Andr\u00e9 Kuipers l\u00e4ks 2004. aastal esimest korda Rahvusvahelisse Kosmosejaama (ISS), valiti tema kaaslaseks C. elegans. Need mikroskoopilised ussid valiti v\u00e4lja seet\u00f5ttu, et nad olid esimesed keerukad elusolendid, kelle k\u00f5ik geenid (keha rakkude ehituskivid) olid kaardistatud.<\/p>\n

Hiljem avastasid teadlased, et seitse usside geeni olid kosmoses v\u00e4hem aktiivsed. \u00dcllatuslikult n\u00e4is, et ussid toimisid ilma nendeta paremini. Tulemused viitasid sellele, et nende lihased kohandusid kosmosetingimustega. Kas kosmoselend v\u00f5iks aeglustada lihaste vananemist?<\/p>\n

Laborikatsed kinnitasid, et ka teistel ussidel, keda kasvatati ilma nende seitsme geenita, oli pikem ja tervem elu. Kuna inimestel on C. elegansiga \u00fchiseid geene umbes 55%, oli j\u00e4rgmiseks sammuks v\u00e4lja selgitada, kuidas inimese lihased reageerivad kosmoselennule.<\/p>\n

Oma teise ISS-i missiooni ajal, mis l\u00f5ppes 1. juulil, v\u00f5ttis Andr\u00e9 kaasa veel usse j\u00e4reluuringu jaoks. Kuid seekord uuriti ka astronauti ennast. Enne missiooni algust v\u00f5eti \u00fchest tema jalast v\u00e4ike lihasproov, mis s\u00e4ilitatakse anal\u00fc\u00fcsimiseks. Teadlased ootavad n\u00fc\u00fcd p\u00f5nevusega, kuidas see proov v\u00f5rdub lihastega, mis on veetnud kuus kuud kaaluta olekus. Erinevalt ussidest antakse Andr\u00e9le aga paar n\u00e4dalat aega, et ta saaks v\u00e4sitavast reisist toibuda, enne kui tema lihased mikroskoobi alla satuvad.<\/p>","protected":false},"excerpt":{"rendered":"
