We have a ” did you know” rubric about Tardigrades (water-bears):

I liked biologist Joe Hanson’s humour which inspired me to write this article and quote him:
“Eat Your Tardigrades or You Don’t Get Dessert!”
You’ve probably eaten them. It looks such as these creatures (0.5 mm long) “live not only on wild mosses and wet plants, but on grocery store produce like lettuce and spinach.” Do you think that a rinse or shake under the water (or even cooking) is enough to dislodge a “radiation-eating” creature? It might be.
Don’t worry if you’ve eaten them, though. It seems they’re harmless. They don’t resist the stomach acid.
You can imagine that ” when you eat them, you absorb their power, and become a little bit mightier.”
So….. “For strength, eat your vegetables and eat your tardigrades!”
Just food for thought or..for dreaming:
Perhaps in order for people to colonize other planets , it will be useful to dig into the study of this kind of creatures which are able to convert radiation into food!!
What do you think about it? Interesting enough? if yes, write about other microorganisms – relatives of tardigrades or not – and explain shortly the Physics involved here.
