Has a cryopreserved human or other mammal been revived ?
Only as embryos. Current science cannot reanimate cryopreserved humans − or other adult mammals − but future science may be able to, by the use of molecular repair technology (including nanotechnology). Although direct evidence does not exist that such technology will ever exist, there is indirect evidence such as increasing understanding molecular biology and increasing control over molecules and atoms in computer chip fabrication. There is no direct evidence that human beings may someday be able to travel to Mars, but there is much indirect evidence that travel to Mars is possible.
