Tardigrades: Microscopic ‘Water Bear’ Can Live On Nearly Some Thing

And no matter what inquiring scientists put them through in the name of science, tardigrade life finds a way.
Instead, tardigrades turn on certain genes to replace the water loss in their cells with proteins that essentially preserve their structure until water is returned.
Japanese scientists did this in 2016 by defrosting and soaking moss containing tardigrades in water.
