Scientists have revealed plans to bring back the extinct Island rat, 119 years after it was wiped out. In a new paper, an international team of academics outline how the use of CRISPR - a gene editing technique which can 'cut and paste' small sections of DNA, deleting or repairing flawed genes - could lead to the rat's 'de-extinction'. Scientists would use CRISPR to edit the DNA of a living rat species to match that of the Christmas Island rat, although the new creation may have some differences compared to the original species.
