Tartigrade superv\u00f5imed on kogu maailmas trendikas teema. Kuid just siis, kui sa arvasid, et loodus ei saa enam hullumeelsemaks muutuda, \u00fcllatab ta sind j\u00e4lle.<\/p>\n

Tartigrade tuntakse juba praegu kui k\u00f5ige vastupidavamaid loomi Maal. Nad said selle sildi t\u00e4nu oma vastupidavusele kiirgusele, k\u00f5rgele survele ja \u00e4\u00e4rmuslikele temperatuuridele. Pole \u00fcllatav, et see v\u00e4ike loom vallandas hulga uusi k\u00fcsimusi selle kohta, kuidas evolutsioon v\u00f5is toimuda.<\/p>\n

\"Tartigrade<\/a><\/p>\n

Sel n\u00e4dalal, uus uurimus, mis on avaldatud ajakirjas Nature<\/a>, selgus palju rohkem tartigrade \u00fcliv\u00f5imete kohta.<\/p>\n

P\u00e4rast tartigrade genoomi sekveneerimist tuvastasid Takekazu Kunieda ja tema teadlaste meeskond valgu, mis kaitseb DNA-d, kui seda kiirgusega kokku puutub. Seda valku leidub ainult tartigrades. Praegu uurib Kunieda aga, kuidas sama valku saaks viia inimestesse ja kaitsta inimese DNA-d.<\/p>\n

\u00a0\"On h\u00e4mmastav n\u00e4ha, et \u00fchestainsast geenist piisab, et parandada inimrakkude kultuuris nende tolerantsust kiirguse suhtes. Me arvame, et see valk v\u00f5ib toimida f\u00fc\u00fcsilise kilbina, mis kaitseb inimese DNA-d r\u00fcnnakute eest.\"<\/p><\/blockquote>\n

Tartigrade superv\u00f5ime saladus on nende v\u00f5ime taluda \u00e4\u00e4rmuslikku kuivamist. Tartigrade suudavad ellu j\u00e4\u00e4da vaid 1% veega ja siis tagasi ellu tulla, nagu poleks midagi juhtunud. Kunieda s\u00f5nul jagavad tartigradid oma DNA-d v\u00e4ikesteks t\u00fckkideks ja langetavad oma eluaktiivsuse 0,01%-ni. Kui nad on uuesti peidetud, parandab DNA end ise ja nende eluaktiivsus t\u00f5useb taas 100%-ni.<\/p>\n

Genoomi sekveneerimine viitab ka sellele, et enamik tartigrade'i geenidest on p\u00e4rit teistelt loomadelt protsessi kaudu, mida nimetatakse \"horisontaalseks geeni\u00fclekandeks\". Siin on infograafiline kokkuv\u00f5te Kunieda uuringutest:<\/p>\n

\"Tartigrade<\/a><\/p>\n

Tartigrade ei pruugi tunduda huvitava uurimisobjektina. Kui aga k\u00fcsida \u00f5iget k\u00fcsimust, v\u00f5ib leida midagi h\u00e4mmastavat, n\u00e4iteks loomade superv\u00f5imed.<\/p>\n

Tunneb p\u00f5nevust Kunieda teadust\u00f6\u00f6 \u00fcle? Noh, veenduge, et ka teadlased on teie teadust\u00f6\u00f6st vaimustuses!<\/p>\n
