Thomas Pesquet: Feeding the tardigrades! Researchers are investigating the effects of microgravity on these microscopic creatures, also known as water bears, through an experiment called Cell Science 4.
#DYK the largest tardigrade species is just over 1mm in length and they’re incredibly hardy – surviving extreme environments in space and on Earth. In this case, researchers want to characterise the genes that allow tardigrades to survive during short and long periods in space, then assess how the use of these genes changes across generations Maybe we can harness their secrets!<\/p>\n

Profession gardien de Zoo \u00e0 mi-temps, il faut assurer le repas bi-hebdomadaire des tardigrades de l’exp\u00e9rience Cell Science 4 ?. Les chercheurs \u00e9tudient les effets de l’impesanteur et de l’environnement spatial sur ces cr\u00e9atures microscopiques qu’on surnomme parfois oursons d’eau. L’esp\u00e8ce la plus grande peut mesurer jusqu’\u00e0 1 mm de long, mais en g\u00e9n\u00e9ral ils sont microscopiques… Ces cr\u00e9atures sont incroyablement r\u00e9sistantes, capables de survivre \u00e0 des environnements extr\u00eames sur Terre comme dans l’espace : certains sont revenus de plusieurs jours \u00e0 l’ext\u00e9rieur, dans le vide, avec des temp\u00e9ratures de +100 \u00e0 -100 degr\u00e9s, sans un dommage… Dans le cas de Cell Science 4, les scientifiques essayent d’identifier les g\u00e8nes qui leur permettent de survivre durant des s\u00e9jours plus ou moins longs dans l’espace, et d’\u00e9valuer comment l’utilisation de ces g\u00e8nes change au cours des g\u00e9n\u00e9rations dans le but d’exploiter pour les humains les secrets de leur incroyable r\u00e9silience !<\/p>\n
