Brutish and short? DNA ‘switch’ sheds light on Neanderthals

NEW YORK (Reuters) – How can creatures as different in body and mind as present-day humans and their extinct Neanderthal cousins be 99.84 percent identical genetically?

Four years after scientists discovered that the two species’ genomes differ by a fraction of a percent, geneticists said on Thursday they have an explanation: the cellular equivalent of “on”/”off” switches that determine whether DNA is activated or not.

In a cloning first, scientists create stem cells from adults

NEW YORK (Reuters) – Scientists have moved a step closer to the goal of creating stem cells perfectly matched to a patient’s DNA in order to treat diseases, they announced on Thursday, creating patient-specific cell lines out of the skin cells of two adult men.

The advance, described online in the journal Cell Stem Cell, is the first time researchers have achieved “therapeutic cloning” of adults. Technically called somatic-cell nuclear transfer, therapeutic cloning means producing embryonic cells genetically identical to a donor, usually for the purpose of using those cells to treat disease.
