Welcome to Sci-Friday!  Every week, we’ll help you head into the weekend by collecting some links from the best real-life science news that happened throughout the week, so you can mix a little reality into your fantasy.

Multiple Studies Confirm There is Water on the Moon

Well, this is certainly where reality meets a long-time science fiction premise in a head-on collision!  The scientific journal Nature Astronomy has published not one but two different studies that found evidence of water molecules and likely water ice on the shadowed side of the Moon.

A Mind-Bogglingly Tiny 3D-Printed USS Voyager That Moves Under its Own Power

Okay, this is just downright geeky cool – a team at Leiden University in The Netherlands have 3D-printed the smallest microscopic self-propelled objects ever, and one of the objects they created was the USS Voyager (well, an unmarked Intrepid-class starship, anyhow).  With the ability to move provided by chemical reaction, the starship measures in at 15 micrometers, so small that it could remain comfortably balanced on a single piece of human hair.

Escaped Cloned Female Mutant Crayfish Take Over Belgian Cemetery

I couldn’t write that headline any better than it was originally written, so that’s a direct quote from the New Zealand Herald, who reported well on this crazy-sounding story.  The self-replicating crustaceans (who are always female) dig deep into the ground to live their lives under the surface, which makes them exponentially more difficult to find and remove.  A group of them – which are technically banned in the European Union – have escaped a scientific breeding program and holed themselves up in the Schoonselhof Cemetery in Antwerp.
