Tardigrades: Now Even Weirder!

 I like tardigrades, the microscopic "water bears" that are most famous for being hard to kill. (You may recall some survived in a habitat stuck on the outside of the International Space Station. Vacuum, extreme temperatures, cosmic rays... yawn.)   A newly discovered species glows blue in ultraviolet (UV) light.  One of the effects of this is that UV light levels used to sterilize surfaces, able to wipe out bacteria, virus, nematode worms, etc.) don't kill it.  It seems you're just giving it a spin in a tanning bed.
