Technology that may let you edit the DNA of your own living cells. MIT and Harvard researchers have developed technologies that could be used to rewrite the genetic code of a living cell, allowing them to make large-scale edits to the cell’s genome. Such technology could enable scientists to design cells that build proteins not found in nature, or engineer bacteria that are resistant to any type of viral infection. The technology can overwrite specific DNA sequences throughout the genome, similar to the find-and-replace function in word-processing programs. Using this technology, researchers can make hundreds of targeted edits to the genome of a cell without disrupting the cells’ function.
