Researchers at Johns Hopkins have made a breakthrough in returning cells to pristine form, perhaps making possible an endless summer, a fountain of youth. What will it be like when we have all the time in the world? From the press release:

“Johns Hopkins scientists have developed a reliable method to turn the clock back on blood cells, restoring them to a primitive stem cell state from which they can then develop into any other type of cell in the body.

The work, described in the Aug. 8 issue of the journal Public Library of Science (PLoS), is ‘Chapter Two’ in an ongoing effort to efficiently and consistently convert adult blood cells into stem cells that are highly qualified for clinical and research use in place of human embryonic stem cells, says Elias Zambidis, M.D., Ph.D., assistant professor of oncology and pediatrics at the Johns Hopkins Institute for Cell Engineering and the Kimmel Cancer Center.

‘Taking a cell from an adult and converting it all the way back to the way it was when that person was a 6-day-old embryo creates a completely new biology toward our understanding of how cells age and what happens when things go wrong, as in cancer development,’ Zambidis says.”
