Institutions have already been amassing huge DNA collections to catalog the world's creatures, but Moscow State University might just top them all. It's planning to build "Noah's Ark," a repository for the genes of every creature, living or extinct -- as long as the genes are readable, they'll either be cryogenically frozen or stored as pure data. Not surprisingly, it's going to be a massive undertaking in more ways than one. The Russian government is spending the equivalent of $194 million on the facility, which should occupy an enormous 166 square miles when it's finished in 2018.
