Japanese scientists have done it with mice that had been frozen for 16 years..
Will extinct species be next? The article quite properly expresses daunting reservations, but I remember when freezing supposedly did irreversible damage to cells.
The prospect of restoring the mammoths gives me chills.
Addendum. According to the NYT, a mammoth might be (re)created for as little as $10M. A Neanderthal might be possible although the means currently available, if I understand the article correctly, exacerbate the serious ethical issues.
