The microworld

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

Water bear. Coloured scanning electron micrograph (SEM) of a water bear (Paramacrobiotus craterlaki) in moss. Water bears (or tardigrades) are tiny invertebrates that live in aquatic and semi-aquatic habitats such as lichen and damp moss. Paramacrobiotus craterlaki is a carnivorous species that feeds on nematodes and rotifers. Water bears are found throughout the world, including regions of extreme temperature, such as hot springs, and extreme pressure, such as deep underwater. They can also survive the high levels of radiation and vacuum of space. Magnification: x330 when printed at 10 centimetres wide.

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.

Please, don’t stop eating vegetables! Just wash them well!
