Scientists have managed to overcome an incredible hurdle that has confounded researchers since Dolly 15 years ago. But researchers from Oregon seem to have finally confirmed (it's not a South Korean hoax this time!) that they have advanced a cloned cell past the stymied 6-12 stage into a 150 cell blastocyst which is enough to serve as a source/reservoir for embryonic stem cells. This is an extraordinary development, and I for one am excited!
