Couple things that came across my radar this week, despite being a few years old.
1) Doggie DNA testing service.
Unsure of the pedigree of that mutt you got at the point? Test their DNA and get a family tree of breeds.
2) Genetically-modded fish, trademarked, owned, and available for purchase as pets!
I was at the petstore with the kids and saw some day-glow (tropical looking) freshwater fish for sale. I noticed a (r) beside the name, Glofish, and thought, hmm, maybe they are GMO fish? Sure enough, yes.
