By Rachel Nowak in Melbourne HEALTHY mice have been cloned from the dead brain cells of animals frozen 16 years ago. The stored mice had been chilled using no elaborate cryogenic techniques, so the hope is that populations of endangered species such as the Northern white rhino (pictured) could one day be boosted using cells extracted from carcasses simply tossed into freezers. Teruhiko Wakayama of the RIKEN Center for Developmental Biology in Kobe, Japan, and colleagues modified a technique Wakayama pioneered in 1998,
