Ohranjanje telesne pripravljenosti in dobre mi\u0161i\u010dne mo\u010di je pravi izziv, saj se mi\u0161ice in kosti v brezte\u017enostnih razmerah ponavadi oslabijo. Plavanje po Mednarodni vesoljski postaji je sicer zelo zabavno, vendar ni dobro za zdravje, \u010de si tam ve\u010d mesecev!<\/p>\n<\/div>\n<p>Znanstveniki iz ESA si prizadevajo astronavtom pomagati pri re\u0161evanju te te\u017eave. Pri tem uporabljajo \u010drva z zanimivim imenom <i>Caenorhabditis elegans<\/i> (<i>C. elegans <\/i>(skraj\u0161ano) jim je pomagal. Ugotovili so, da so mi\u0161ice v <i>C. elegans<\/i> se v brezte\u017enosti spreminjajo na zelo podoben na\u010din kot \u010dlove\u0161ke mi\u0161ice. Morda bi se ti drobni \u010drvi \u2013 vsak dolg manj kot 1 mm \u2013 lahko uporabili v okviru vesoljskih poskusov, da bi pripomogli k tej raziskavi?<\/p>\n<figure class=\"wp-block-image size-large\" data-width=\"4928\" data-credit=\"ESA\/NASA\" data-detail-url=\"https:\/\/www.esa.int\/ESA_Multimedia\/Images\/2015\/09\/Samantha_running_in_space\" data-licence=\"ESA Standard Licence\" data-licence-url=\"https:\/\/www.esa.int\/ESA_Multimedia\/Terms_and_conditions_of_use_of_images_and_videos_available_on_the_esa_website\"><img decoding=\"async\" loading=\"lazy\" style=\"max-width:100%;height:auto\" src=\"https:\/\/www.esa.int\/var\/esa\/storage\/images\/esa_multimedia\/images\/2015\/09\/samantha_running_in_space\/15629558-1-eng-GB\/Samantha_running_in_space.jpg\" alt=\"Samantha running in space\"><figcaption>Samantha te\u010de v vesolju<\/figcaption><\/figure>\n<p>Tim Etheridge je vi\u0161ji predavatelj na Univerzi v Exeterju v Veliki Britaniji.

Nato so jih nalo\u017eili na vesoljsko plovilo \u00bbDragon\u00ab in jih izstrelili na Mednarodno vesoljsko postajo! Astronavt ESA Alexander Gerst je \u010drve postavil v inkubator, zasnovan tako, da jim pomaga hitro in varno rasti. Manj kot teden dni kasneje so bili \u017ee v celoti odrasli, vse to v brezte\u017enostnih razmerah. \u010crvi so bili nato zamrznjeni, pripravljeni za vrnitev na Zemljo za nadaljnje raziskave. Medtem so bile druge skupine \u010drvov vzrejene v normalnih razmerah na Zemlji, da bi lahko primerjali razlike.<\/p>\n<p>Znanstveniki misije upajo, da nam bo poskus pomagal izvedeti ve\u010d tudi o mo\u017enem vzroku sladkorne bolezni ter o bolezni, imenovani mi\u0161i\u010dna distrofija, pri kateri se mi\u0161ice oslabijo in razgradijo.
