I recently interviewed the founders of the Rejuvenation Science Institute in Brazil. This is a recent non-profit effort founded by Nicholas Chenovsky and Nina Torres-Zanvettor.
They are undertaking an ambitious effort to reproduce Dr. Harold Katcher's rejuvenation experiment in mice. Replication is VERY important and they are raising money to fund this effort.
