SPOILERS: It's from the Three Body Problem TV series, where the aliens on a planet in that three-body star system have to survive very extreme changes as their planet gets thrown out far from the suns temporarily. So they can desiccate and be reanimated as a survival feature. They don't really look like humans, but it was translated into human representation to explain it to the humans in the TV series in a kind of VR simulation. So I guess the link to tardigrades is the reanimation after desiccation.

[@LightbringerDesigns]

The biggest problem I see is that all of these protective mechanisms require dessication & inactivity - the special proteins typically float around & let DNA act normally. That would imply that for this to potentially work for humans, we'd need to simultaneously dry all of our cells out during the time exposed to these hazards, then reverse the process. I'd expect that different soft tissues would contract different amounts when dried, & bones least of all, so it would tear your body to pieces. So, MAYBE it could work with a stasis-state, but if we're conscious, we'd be vulnerable to radiation etc again. DNA needs to temporarily "unzip" to create RNA molecules that manufacture proteins in order to function, so even if you COULD trigger them to work without drying, again you'd be unable to move or think or anything else.

They look extraordinary just from our narrow persppective. Every single known life form has developed their own set of remarquable set of survival skills. Otherwise they would not exist anymore. The level of these skills of course vary from one species to another. The tardigrades skills are perhaps rhe most extreme one - on Earth. There has to be a most extreme one, if the tardigrades would not exist the current number 2, whatever it is, would be the most extreme one.

Great video on going relatively in-depth into our knowledge and the history of that knowledge about tardigrades.

[@nemonomen3340]

It’s worth mentioning that, while tardigrades have been shown to survive extreme cold, extreme dehydration, extreme radiation, and other such extremes, there are actually many, _many_ species of unique tardigrade and not all are as well adapted to surviving certain conditions as others. (Basically there isn’t a single tardigrade that is excellent at all of these so far as we know)

[@VMK86x]

That is correct. There are over 1000 species of Tardigrade. (It's actually a phylum, on the same level as "Chordate" is, which includes everyone from Fish to Mamals, though as mentioned, Tardigrades are not nearly as numerous)
