Let do vesm\u00edru je vzru\u0161uj\u00edc\u00ed dobrodru\u017estv\u00ed, ale pro astronauty jsou n\u011bkter\u00e9 v\u011bci velmi n\u00e1ro\u010dn\u00e9. Udr\u017eet si kondici a dobrou svalovou s\u00edlu je opravdov\u00e1 v\u00fdzva, proto\u017ee svaly a kosti maj\u00ed ve stavu bezt\u00ed\u017ee tendenci sl\u00e1bnout. Vzn\u00e1\u0161et se po Mezin\u00e1rodn\u00ed vesm\u00edrn\u00e9 stanici je sice velk\u00e1 z\u00e1bava, ale pokud tam str\u00e1v\u00edte mnoho m\u011bs\u00edc\u016f, nen\u00ed to pro zdrav\u00ed zrovna dobr\u00e9!<\/p>\n<\/div>\n

V\u011bdci z ESA se sna\u017e\u00ed astronaut\u016fm pomoci tento probl\u00e9m p\u0159ekonat. Vyu\u017e\u00edvaj\u00ed k tomu \u010derva s chytlav\u00fdm n\u00e1zvem Caenorhabditis elegans<\/i> (C. elegans <\/i>(zkr\u00e1cen\u011b) jim pomoci. Zjistili, \u017ee svaly v C. elegans<\/i> v bezt\u00ed\u017en\u00e9m stavu se m\u011bn\u00ed velmi podobn\u011b jako lidsk\u00e9 svaly.
