Japanese scientists have cloned healthy mice from bodies kept in deep freeze for 16 years.

The breakthrough increases the possibility of "resurrecting" extinct animals such as mammoths from their frozen remains.

Until now Dolly the Sheep-style cloning has only been achieved using live donor cells, from which DNA is transferred to recipient eggs.

Cloning from thawed frozen cells was thought to be difficult, if not impossible, because their DNA would be damaged by ice crystals.

This presented a major obstacle to hopes of raising mammoths and other extinct animals preserved in ice from the dead.

But a team of scientists from the Centre for Developmental Biology in Kobe, Japan, has now overcome the problem by successfully producing mouse clones from mice frozen at minus 20C for up to 16 years.

After thawing out the dead mice, the researchers collected nuclei from cells in their brain tissue.

These were injected into empty eggs whose own DNA had been removed, to generate cloned embryos.

Stem cells taken from the embryos were then used in a second round of cloning. Their genetic material was inserted into denucleated eggs, to produce embryos that grew into four mouse clones.

Voted COLD. LMFAO.
I'd bring back Robert Maxwell and ask him why he did what he did to those poor pensioners.

I think there barking mad , when there is so many serious ilness's about . ie Cancer , Parkingsons etc and theres scientists somewhere working on how to bring back dinasaurs ,crossing some animal with another , growing ears on mices backs ,trying to find out what caused the Big Bang .
I wish they would use there expertize on something valid , like trying to find the Iceberg that sank the Titanic etc .

Awesome!!!

It is good in away but i think its stupid wasting money doing these kind of experiments insted of using that money to help humans and animls that are alive and not extinct
