Gene editing probably isn’t the first method that comes to mind for keeping your brain young. However, recent research suggests that the DNA-modification technology known as CRISPR has the potential to rejuvenate our stem cells and reverse ageing. Stem cells are unspecialised cells that are capable of dividing and renewing into specific, differentiated cells.
While the technology is a long way from being used in humans, fresh breakthroughs could prove significant in fundamental biology. Specifically, scientists may have found a way to boost the ability of old stem cells in your brain to produce young new cells, rejuvenating the organ.
