Bringing Mammoths Back from Extinction?

John also passes this along:

Bone marrow and muscle tissue were extracted from the remains of a mammoth named Yuka that had been frozen in Siberian permafrost for 28,000 years in the study, published online in the journal Scientific Reports. Genomic DNA was compared against that of elephants, and the researchers confirmed that Yuka's DNA overlapped with the DNA and proteins specific to mammoths.

The team injected cell nuclei from the muscle tissue into mouse egg cells and observed the forming of structures that appear just before cell division starts. The researchers also found possible signs of repair to damaged mammoth DNA.

This marks a "significant step toward bringing mammoths back from the dead," said researcher Kei Miyamoto, one of the study's authors.
