Powerful whole-species gene editing tool fails first tests in mice
When it comes to mammals, both the optimism and the fears about gene drives are overblown. So say a team who have tested the concept in mice for the first time. Their studies in mice suggests that existing gene drives don’t work nearly well enough to be used to eliminate mammalian pests – invasive rodents on islands, for instance. On the flip side, this means that gene drives would pose little danger to, say, wild mice if one somehow got out of a lab.
