De superkrachten van de tartigrades zijn een trending topic over de hele wereld. Maar net als je dacht dat de natuur niet gekker kon worden, verrast ze je weer.<\/p>\n

Tartigrades staan al bekend als de meest resistente dieren op aarde. Ze kregen dit label vanwege hun weerstand tegen straling, hoge druk en extreme temperaturen. Het is geen verrassing dat dit diertje een reeks nieuwe vragen heeft losgemaakt over hoe de evolutie heeft kunnen plaatsvinden.<\/p>\n

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

Deze week, een nieuw onderzoek gepubliceerd in Nature<\/a>onthulde veel meer over de tartigrades superkrachten.<\/p>\n

Na sequentiebepaling van het genoom van tartigrades hebben Takekazu Kunieda en zijn team wetenschappers een eiwit ontdekt dat het DNA beschermt bij blootstelling aan straling. Dit eiwit komt alleen voor bij tartigrades. Kunieda bestudeert momenteel echter hoe hetzelfde eiwit bij mensen kan worden ingebracht en het menselijke DNA kan beschermen.<\/p>\n

\u00a0\"Het is verbazingwekkend dat een enkel gen voldoende is om in een cultuur van menselijke cellen hun tolerantie tegen straling te verbeteren. We denken dat dit eiwit kan functioneren als een fysiek schild om menselijk DNA te beschermen tegen aanvallen.\"<\/p><\/blockquote>\n

Het geheim van de tartigrades superkrachten is hun vermogen om extreme droogte te weerstaan. Tartigrades kunnen overleven met slechts 1% water en dan weer tot leven komen alsof er niets is gebeurd. Volgens Kunieda delen tartigrades hun DNA in kleine stukjes en daalt hun levensactiviteit tot 0,01%. Eenmaal weer ondergedompeld, repareert het DNA zichzelf en gaat hun levensactiviteit terug naar 100%.<\/p>\n

De genoomsequencing suggereert ook dat de meeste genen van tartigrades afkomstig zijn van andere dieren via een proces dat \"Horizontale Genoverdracht\" heet. Hier is een infographic die het onderzoek van Kunieda samenvat:<\/p>\n

Tartigrades lijken misschien geen interessant studieobject. Maar als je de juiste vraag stelt, kun je iets verbazingwekkends vinden, zoals superkrachten van dieren.<\/p>\n

Ben je enthousiast over Kunieda wetenschappelijk artikel? Nou, zorg ervoor dat wetenschappers ook enthousiast worden over jouw onderzoek!<\/p>\n
